Residential Building Permit
VerifiedRequired for new single-family and two-family residential construction and any work regulated by the adopted IRC/IBC in Plain City. Plain City's Building Department (independent of Weber County — staffed by its own Building Inspector) reviews plans against a detailed published submittal checklist. No dollar-figure valuation-based fee table is restated in the city's standalone Consolidated Fee Schedule (Resolution #2024-07), but a 2026-07-23 re-chase found the actual governing fee mechanism the earlier searches never cross-checked against this entry: Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE,' adopts Table 1-A of the 1997 Uniform Building Code as the valuation-based fee table for all IBC-authorized building permits citywide (the same mechanism already established elsewhere in this file for the Solar PV, Fire Sprinkler, and Fire Alarm Permit entries, but never previously applied back to this base Residential Building Permit entry) — see the fees array for the full table.

| Building Permit Fee (residential, valuation-based — 1997 UBC Table 1-A) | Valuation-based per Table 1-A of the 1997 Uniform Building Code — not a fixed dollar figure. Example brackets: $1-$500 valuation = $23.50; $501-$2,000 = $23.50 + $3.05 per additional $100 (or fraction) up to $2,000; $2,001-$25,000 = $69.25 + $14.00 per additional $1,000 (or fraction) up to $25,000; $25,001-$50,000 = $391.75 + $10.10 per additional $1,000 up to $50,000; $50,001-$100,000 = $643.75 + $7.00 per additional $1,000 up to $100,000; $100,001-$500,000 = $993.75 + $5.60 per additional $1,000 up to $500,000; $500,001-$1,000,000 = $3,233.75 + $4.75 per additional $1,000 up to $1,000,000; over $1,000,000 = $5,608.75 + $3.65 per additional $1,000. | CLOSED 2026-07-23. The 2026-07-08/07-20 chases on this specific entry searched the Building Department page, Fee Schedule (Resolution #2024-07), Residential Building Permit Plan Submittal Requirements, and the amlegal municipal code but never cross-checked the fee mechanism separately discovered on 2026-07-21 for this file's Solar PV Permit entry (and later reused for Fire Sprinkler/Fire Alarm) — that gap is the same gap as this one. Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (Title 9, Building Code; amd. Ord. 2025-08, 6-19-2025; re-fetched and re-verified live 2026-07-23 at codelibrary.amlegal.com), states verbatim: 'Fees authorized in the IBC for inspections, permits, certificates and other purposes shall be governed by table 1-A of the 1997 edition of the uniform building code promulgated by the International Conference of Building Officials, or as may otherwise be adopted by the state.' A residential building permit under the current adopted IBC is squarely 'authorized in the IBC' — this is in fact the base building permit that the solar/fire entries themselves route through, so § 9-1-4 applies here even more directly. Plain City's standalone Consolidated Fee Schedule (Resolution #2024-07) does not restate this table because it is incorporated into the municipal code by reference rather than restated in the fee resolution; both documents had to be checked and now have been. Because actual project valuation varies, no single dollar figure applies — submit the project's estimated valuation to the Building Department at (801) 731-4908 for the calculated figure. |
Detached Accessory Dwelling Unit (DADU) Permit
VerifiedRequired for a Detached Accessory Dwelling Unit in Plain City — a detached structure, or a unit above/behind a detached garage, associated with a single-family dwelling. Governed by Plain City Code § 10-21 (adopted by Ord. 2022-10, 7-21-2022). Requires staff approval prior to issuance of the underlying building permit.

Commercial Building Permit
VerifiedRequired for new commercial construction in Plain City. Plain City requires Planning Commission approval of a Non-Residential Site Plan as a prerequisite to the building permit itself — the city publishes a detailed site plan checklist and a $200 Site Plan filing fee. No dollar-figure valuation-based commercial building permit fee table is restated in Plain City's Consolidated Fee Schedule, but a 2026-07-23 re-chase closed this the same way as the Residential Building Permit entry in this file: Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE,' adopts Table 1-A of the 1997 Uniform Building Code as the valuation-based fee table for all IBC-authorized building permits citywide — see the fees array for the full table.
Verified 2026-07-23 · Source
Requirements
- New commercial or non-residential construction regulated by the current adopted IBC (statewide, per Utah Code § 15A-2-103), subject to Plain City Code § 9-1-1
- Non-Residential Site Plan Plat approval from the Plain City Planning Commission is a prerequisite — the completed application and supporting documents must be submitted at least 30 days prior to a Planning Commission meeting (2nd and 4th Thursdays of the month), per the city's official Site Plan Application (New Construction) packet
- Traffic Impact Analysis, when required by the City Engineer
- A title certificate from a title insurance company or attorney listing all property owners, mortgages, judgments, liens, easements, and agreements of record affecting the plat

All Engineer, Legal, and Planner fees are separately billed to the applicant and must be paid in full before any building permit shall be issued. |
| Building Permit Fee (commercial, valuation-based — 1997 UBC Table 1-A) | Valuation-based per Table 1-A of the 1997 Uniform Building Code — not a fixed dollar figure. Example brackets: $1-$500 valuation = $23.50; $501-$2,000 = $23.50 + $3.05 per additional $100 (or fraction) up to $2,000; $2,001-$25,000 = $69.25 + $14.00 per additional $1,000 (or fraction) up to $25,000; $25,001-$50,000 = $391.75 + $10.10 per additional $1,000 up to $50,000; $50,001-$100,000 = $643.75 + $7.00 per additional $1,000 up to $100,000; $100,001-$500,000 = $993.75 + $5.60 per additional $1,000 up to $500,000; $500,001-$1,000,000 = $3,233.75 + $4.75 per additional $1,000 up to $1,000,000; over $1,000,000 = $5,608.75 + $3.65 per additional $1,000. | CLOSED 2026-07-23. The 2026-07-19 chase on this entry reviewed the Building Department page, general Fee Schedule (Resolution #2024-07), Non-Residential Site Plan Plat Checklist, and the amlegal municipal code, but never cross-checked the fee mechanism separately discovered on 2026-07-21 for this file's Solar PV Permit entry (later reused for Fire Sprinkler/Fire Alarm) — that is the same gap. Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (Title 9, Building Code; amd. Ord. 2025-08, 6-19-2025; re-fetched and re-verified live 2026-07-23), states: 'Fees authorized in the IBC for inspections, permits, certificates and other purposes shall be governed by table 1-A of the 1997 edition of the uniform building code promulgated by the International Conference of Building Officials, or as may otherwise be adopted by the state.' The statute text is not scoped to residential-only construction — a commercial/non-residential building permit under the current adopted IBC (Utah Code § 15A-2-103) is equally 'authorized in the IBC.' This governs in addition to, not instead of, the separately-published $200.00 Site Plan Review Fee, which remains a Planning Commission prerequisite billed before the building permit itself is issued. Because actual project valuation varies, no single base-permit dollar figure applies — submit the project's estimated valuation to the Building Department at (801) 731-4908 for the calculated figure. |
Commercial Tenant Improvement / Tenant Finish Permit
VerifiedRequired for tenant improvement / minor remodel work in an existing commercial building in Plain City where the use does not change. Plain City's process for this scope is its 'Site Plan Application (Existing Commercial Building - same use, minimal remodeling)' — a faster-track site plan review (7-day advance submittal) than the Non-Residential Site Plan Plat Checklist required for new commercial construction (30-day advance submittal). A 2026-07-23 re-chase found that the base building-permit fee for this scope of work, previously marked 'not found published,' is in fact governed by Plain City Municipal Code § 9-1-4 (Table 1-A of the 1997 Uniform Building Code) — the same mechanism already established elsewhere in this file — see the fees array for the full table.

Requirements
- Existing commercial building, same use, minimal remodeling — per Plain City's official 'Site Plan Application (Existing Commercial Building)' form
- Completed application and supporting documents must be submitted at least 7 days prior to a Planning Commission meeting (2nd and 4th Thursdays of the month) — a shorter lead time than the 30-day requirement for new construction
- A detailed site plan showing parking, landscaping, building footprint, and the proposed floor plan for the business, including restrooms, windows, and outside doors, per the official form

| Site Plan Review Fee (Planning Commission prerequisite) | $200.00 | The Site Plan Application (Existing Commercial Building) form (Doc 508) does not repeat a fee table itself, but Plain City's Site Plan Inspection Fee Schedule (in the companion New Construction packet, Doc 500, page 3) lists a single generic 'Site Plan ... $200.00' line item under USER FEES that is not restricted to new construction. Used here as the applicable site plan fee for the existing-commercial process; confirm with the Planning Department that the same $200 figure applies to the shorter existing-building track. |

The 2026-07-19 chase on this entry reviewed the Fee Schedule (Resolution #2024-07), Building Department page, and both Site Plan Application packets, but never cross-checked the fee mechanism separately discovered on 2026-07-21 for this file's Solar PV Permit entry (later reused for Fire Sprinkler/Fire Alarm/Residential/Commercial Building Permit) — same gap. Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (re-fetched and re-verified live 2026-07-23), states: 'Fees authorized in the IBC for inspections, permits, certificates and other purposes shall be governed by table 1-A of the 1997 edition of the uniform building code...' Tenant-improvement work regulated by the adopted IBC is 'authorized in the IBC' just as new construction is, so the same Table 1-A mechanism applies. This governs in addition to, not instead of, the separately-published $200.00 Site Plan Review Fee for the existing-building track. Because actual project valuation varies, no single base-permit dollar figure applies — submit the project's estimated valuation to the Building Department at (801) 731-4908 for the calculated figure. |
Sign Permit
Plain City requires a sign permit from the Chief Building Official before any sign is erected, maintained, or remodeled on public or private property, per City Code § 10-12-5(J). The city's Sign Regulations chapter (Title 10, Chapter 12) sets detailed size, copy-area, clearance, and location standards, but Plain City's published Consolidated Fee Schedule does not break out a distinct dollar sign-permit fee — sign permits appear to be assessed under the same Council-set fee structure as other zoning/building permits.
Reviewed 2026-07-20 · Source
Requirements
- It shall be unlawful to erect or maintain or remodel any sign upon or over public or private property within the city until a sign permit has been obtained from the Chief Building Official, per § 10-12-5(J)
- Copy area of building facade signs or multiple copy signs shall not exceed 20% of the background facing to which it is applied, per § 10-12-5(C)
- Minimum clearance of 10 feet between finished grade and the bottom of a projecting sign (nameplates, public necessity signs, and monument signs excepted), per § 10-12-5(B)
- The following signs are exempt from a sign permit/zoning regulations: memorial tablets; nameplates ≤2 sq ft; nonilluminated real estate/construction signs ≤36 sq ft (max 1 per street frontage, erected no more than 30 days before construction and removed within 30 days after completion); nonilluminated religious/charitable/educational ground signs ≤12 sq ft; and nonilluminated professional/home-occupation signs ≤4 sq ft, per § 10-12-7
- Specialty signs — wind signs, banner signs, portable signs, A-frame signs, and other specialty signs — are prohibited in the city, per § 10-12-9
- Off-premise signs (billboards) are prohibited; legally existing off-premise signs made nonconforming by the current ordinance must be removed within 5 years of written notice, per § 10-12-10(A)

| Sign Permit | Not separately published — assessed under the general Council-set permit fee structure | Plain City's Consolidated Fee Schedule (Resolution 2024-07 exhibit, revision 06/06/2024) does not list a distinct sign-permit dollar fee; City Code § 10-1-5(L) ("Fees Prescribed By City Council") states the City Council may, by resolution, prescribe fees to cover the expense of examining plans, issuing building permits, inspecting uses, and issuing certificates of occupancy (verified live 2026-07-22 against the actual ordinance text -- § 10-1-6 is the Building Permit section itself and has no subsection L; the fee-authorization clause is § 10-1-5(L), corrected from an earlier miscitation). A 2026-07-20 re-chase re-fetched and visually rendered the full Resolution 2024-07 fee table (every line item, Monthly Service Fees through RV Temporary Occupancy Permit) -- confirmed it is genuinely a single page with no Sign Permit or general Building Permit valuation-fee line item at all; checked Plain City's Forms/Applications/Fees page for a separate building-permit valuation fee table and found none published. Confirm the current sign-specific fee amount directly with the Plain City Building Department. A second re-chase on 2026-07-20 tried further avenues: (1) checked whether Plain City contracts building/sign permitting to Weber County (as some smaller Weber County cities do, e.g. Riverdale for some services) -- ruled out: Plain City Code § 9-1-3 confirms the city runs its own in-house process (application forwarded from the City Recorder to the city's own Building Inspector, who returns plans within 10 days), not a county-run process, so no county fee schedule applies. (2) Found and checked Plain City's alternate/mirror domain, plaincityutah.org (indexed alongside the .gov site, same CivicPlus-family platform), including its own 'Building' page (fetched via Wayback since the live domain did not respond) -- content matches the .gov site with no additional or different fee-schedule PDF. (3) Read Plain City Council's January 15, 2026 regular meeting minutes in full (245KB PDF) -- confirmed a real agenda item, 'A site plan was reviewed for a sign for Sunflower Assisted Living' (a Planning Commission report item), but the minutes record only that the site plan was reviewed, with no fee amount, resolution, or dollar figure discussed anywhere in the document. (4) Ran a full CDX (Wayback) sweep of plaincityutah.gov for every URL containing 'fee' -- confirmed only the same Resolution 2024-07 Fee Schedule and an unrelated Parks & Facilities Reservation Fees document exist; no separate sign or building valuation fee document has ever been published on the domain. No new dollar figure was recovered; this remains genuinely unpublished. A THIRD re-chase on 2026-07-23 specifically tested whether the § 9-1-4 fee mechanism separately established elsewhere in this file (Table 1-A of the 1997 UBC, used to close the Residential/Commercial/Tenant-Improvement/EV-Charger Building Permit fee gaps in this same file on this same date) could close this gap too -- it does not transfer cleanly: § 9-1-4 sits in Title 9 ('Building Code') and is textually scoped to 'fees authorized in the IBC,' whereas Plain City's sign permit requirement lives in Title 10, Chapter 12 ('Sign Regulations'), a zoning-title provision enforced under the separate general fee-authorization clause at § 10-1-5(L) ('Fees Prescribed By City Council') -- itself confirmed (re-fetched live 2026-07-23) to state only that the Council 'may, by resolution, prescribe fees,' with no dollar figure or cross-reference to Table 1-A. Also checked and ruled out on 2026-07-23: (1) Plain City's Forms & Applications page (plaincityutah.gov/1308/Forms-Applications, re-fetched live) lists no standalone 'Sign Permit Application' document at all among its ~35 forms -- confirming there truly is no distinct sign-permit intake with its own printed fee to check; (2) Plain City Code § 10-1-6 ('Building Permit'), the Title 10 zoning-title permit-requirement section adjoining the sign code, was re-fetched live and requires only 'a written permit... by the chief building official' for 'any structure,' with no fee language or Table 1-A cross-reference of its own. Extending § 9-1-4's IBC-scoped language to a Title-10 zoning sign permit would require an invented linkage this file's zero-fabrication policy does not permit -- the gap remains genuinely open pending direct confirmation from the Building Department. |
Solar PV Installation Permit
VerifiedPlain City has a genuinely distinct Residential Solar Photovoltaic (PV) System Plan Submittal Requirements checklist (Doc 476) — a separate, solar-specific plan submittal list distinct from the general Residential Building Permit checklist (Doc 475) — but the underlying permit is still applied for and issued as a standard Building Permit Application through the city's Online Building Permit Portal, not as a separately named or separately priced permit type. No distinct dollar-figure solar-specific fee line is published, and Plain City's Consolidated Fee Schedule (Resolution #2024-07, Exhibit A, revision 06/06/2024) has no 'solar,' 'photovoltaic,' 'PV,' or general building-permit valuation line item anywhere in it. However, an independent second-pass re-chase (2026-07-21) found the actual governing fee mechanism the first pass missed: Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (Title 9, Building Code, amd. Ord. 2025-08, 6-19-2025), expressly adopts Table 1-A of the 1997 Uniform Building Code as the valuation-based fee table governing all IBC-authorized building permit fees citywide — it is simply incorporated by reference in the municipal code rather than restated in the standalone Consolidated Fee Schedule resolution. See the fees array for the full table.

Example brackets: $1-$500 valuation = $23.50; $501-$2,000 = $23.50 + $3.05 per additional $100 (or fraction) up to $2,000; $2,001-$25,000 = $69.25 + $14.00 per additional $1,000 (or fraction) up to $25,000; $25,001-$50,000 = $391.75 + $10.10 per additional $1,000 up to $50,000; $50,001-$100,000 = $643.75 + $7.00 per additional $1,000 up to $100,000; $100,001-$500,000 = $993.75 + $5.60 per additional $1,000 up to $500,000; $500,001-$1,000,000 = $3,233.75 + $4.75 per additional $1,000 up to $1,000,000; over $1,000,000 = $5,608.75 + $3.65 per additional $1,000. | Independent second-pass re-chase (2026-07-21) of the original 'no fee found' finding. Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (Title 9, Chapter 1, Building Code; amd. Ord. 2025-08, 6-19-2025) states: 'Fees authorized in the IBC for inspections, permits, certificates and other purposes shall be governed by table 1-A of the 1997 edition of the uniform building code promulgated by the International Conference of Building Officials, or as may otherwise be adopted by the state.' This is the actual governing fee authority for Plain City building permits (including solar PV, issued as a standard Building Permit per this entry's own findings) — it is not restated in the city's standalone Consolidated Fee Schedule (Resolution #2024-07), which is why that document alone showed no line item; the two documents govern different things and both had to be checked. Plain City's adopted building CODE itself is the current statewide-amended IBC (auto-updated per Utah Admin. Code R156-56-704, per Plain City Code § 9-1-1) — only the FEE table specifically still cites the legacy, nationally-standardized 1997 UBC Table 1-A, last reaffirmed by Ord. 2025-08 (6-19-2025), so this is current law, not a stale citation. Table 1-A's dollar figures (static and unchanged since 1997) were cross-verified against a government reproduction of the same table: Storey County, Nevada's official fee document (storeycounty.org/DocumentCenter/View/20579/Building-Fees), which lists the identical figures verbatim under the same 'Table 1-A - Building Permit Fees' title. Because actual system valuation varies per installation, no single dollar figure applies, but the governing calculation is now confirmed and cited rather than genuinely absent. Plain City's own 9-1-4 does not separately restate the table's numbers — for a hard invoice figure, submit the project's estimated valuation to the Building Department at (801) 731-4908 for their calculation. |
EV Charger / EVSE Permit
VerifiedPlain City has no distinct EV charger/EVSE permit type, and no dedicated Electrical Permit type either — EV charger/EVSE installation is electrical work that falls under the city's general Residential Building Permit, submitted through the same Online Building Permit Portal. A fresh check of Plain City's Fee Schedule (Resolution #2024-07, Exhibit A) found no 'EV,' 'electric vehicle,' or 'EVSE' mention anywhere in the document, and no base building-permit fee is restated there at all. A 2026-07-23 re-chase closed this gap the same way it was closed for the underlying Residential Building Permit entry in this file: Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE,' adopts Table 1-A of the 1997 Uniform Building Code as the valuation-based fee table governing all IBC-authorized building permits citywide, and since an EV charger permit is issued as that same Building Permit, the same fee mechanism applies — see the fees array for the full table.

The 2026-07-20 chase on this entry checked the Building Department page, Fee Schedule (Resolution #2024-07), and the amlegal municipal code but never cross-checked the fee mechanism separately discovered on 2026-07-21 for this file's Solar PV Permit entry (later reused for Fire Sprinkler/Fire Alarm/Residential/Commercial/Tenant-Improvement Building Permit entries) — same gap. This entry's own description already established that an EV charger permit IS the general Residential Building Permit (same portal, same application, no distinct EV-specific permit type), so once that base fee was resolved via Plain City Municipal Code § 9-1-4 (Table 1-A of the 1997 UBC, re-verified live 2026-07-23), it necessarily governs EV charger installations too. Because actual project valuation varies, no single dollar figure applies — submit the project's estimated valuation to the Building Department at (801) 731-4908 for the calculated figure. |
Fire Sprinkler System Permit
VerifiedPlain City has no distinct fire-sprinkler-specific permit application, portal, or fee schedule — a full search of the Building Department page, the Forms & Applications page (12 Buildings-category documents, none fire-related), the Consolidated Fee Schedule (Resolution #2024-07, Exhibit A), and Plain City Code Title 4, Chapter 1 (Fire Department — purely administrative fire-chief-duties provisions, §§4-1-1 through 4-1-5) turned up no fire-sprinkler permit, checklist, or dollar fee anywhere on plaincityutah.gov. The underlying legal requirement is real, however: Utah's State Fire Code Act (Utah Code Title 15A, Chapter 5) adopts the 2024 International Fire Code (IFC) for statewide application (§15A-5-103), defines the enforcing 'AHJ' as the State Fire Marshal, an authorized deputy, or 'the local fire enforcement authority' (§15A-5-102(2)) — a role Plain City's own independent Fire Chief fills, since Plain City is confirmed NOT a member of the Weber Fire District that serves several neighboring Weber County cities — and a 2015-enacted statewide IFC amendment (§15A-5-202(1)(c)) requires that 'fire sprinkler system layout shall be prepared and submitted by a person certified by the National Institute for Certification in Engineering Technologies [NICET] at level III or IV in Water-Based System Layout.' Because Plain City publishes no separate fire-permit intake of any kind, and its only published construction-permit channel is the Online Building Permit Portal (the same one used for the general Building Permit, Solar PV Permit, and EV Charger Permit entries in this file), a fire sprinkler installation is submitted through that same portal as a Building Permit Application, whose fee is governed — per the same finding already made for the Solar PV Permit entry in this file — by Plain City Municipal Code §9-1-4, which adopts Table 1-A of the 1997 Uniform Building Code as the valuation-based fee table for 'fees authorized in the IBC for inspections, permits, certificates and other purposes' (the IBC's own Chapter 9, Fire Protection Systems, governs sprinkler system design/installation as part of the building code).

Weber Fire District — which publishes its own distinct, itemized Fire Sprinkler System plan-review and permit fee schedule (e.g., plan review scaled by sprinkler-head count, permit fee including 2 inspections) for the several Weber County cities it serves — does NOT serve Plain City (confirmed via Weber Fire District's own About Us/member-city listing), so that fee schedule does not apply here and is not used to fill this gap.

Fire Alarm System Permit
VerifiedPlain City has no distinct fire-alarm-specific permit application, portal, or fee schedule — the same exhaustive search performed for the Fire Sprinkler System Permit entry in this file (Building Department page, Forms & Applications page, Consolidated Fee Schedule Resolution #2024-07, and Plain City Code Title 4, Chapter 1, Fire Department) found no fire-alarm permit, checklist, or dollar fee published anywhere on plaincityutah.gov. As with fire sprinkler systems, the underlying legal requirement is real: fire alarm and detection systems are regulated under the statewide-adopted 2024 International Fire Code (Utah Code §15A-5-103) and IBC Chapter 9 (Fire Protection Systems), and Utah's statewide IFC amendment at §15A-5-202(1)(c) requires that 'fire alarm system layout shall be prepared and submitted by a person certified by the National Institute for Certification in Engineering Technologies [NICET] at level III or IV in Fire Alarm Systems.' Because Plain City has no separate fire-permit intake, a fire alarm installation is submitted through the same Online Building Permit Portal used for the general Building Permit, Solar PV Permit, and EV Charger Permit, with its fee governed — per the same finding made for the Solar PV Permit entry — by Municipal Code §9-1-4's adoption of 1997 UBC Table 1-A.

Change of Use / Certificate of Occupancy Permit
VerifiedPlain City does not publish a standalone 'Change of Use Permit' application, checklist, or fee — no such document appears on the Forms & Applications page or the Consolidated Fee Schedule (Resolution #2024-07). Instead, a change in the use of land or of an existing building is governed by two general provisions of Plain City Code Title 10, Chapter 1: §10-1-7 (Certificate Of Occupancy), which requires that 'no land shall be used or occupied and no building hereafter structurally altered or erected shall be used or in use until a certificate of occupancy shall have been issued by the chief building official stating that the building or structure or the proposed use thereof, or the use of land, complies with the provisions of this title,' and §10-1-8 (Issuance Of Licenses And Permits), which bars any city official from issuing a permit or license that would conflict with the zoning title. In practice, a change of use in an existing commercial building is processed through the same 'Site Plan Application (Existing Commercial Building)' track documented in this file's Commercial Tenant Improvement entry (Doc 508, 7-day advance submittal before a Planning Commission meeting), paired with a Commercial Business License Application (Doc 383) if a business use is involved — that license application independently confirms Site Plan Approval from the Planning Commission is a prerequisite and requires sign-off from both the Fire Marshal and the Building Inspector before issuance. Unlike several other gap entries in this file, a real, distinct, published fee for this exact existing-building site-plan scenario does exist: Plain City's Fee Schedule (Resolution #2024-07, Exhibit A, Filing Fees section) lists 'Site Plan - existing building with no remodel — $100.00,' separate from the $200.00 new-building Site Plan fee, plus the $60.00/year Commercial Business License base fee if a business is being established.

Requirements
- A change in the use of land, or of an existing building/structure, that does not involve new construction — processed as a same-track variant of Plain City's existing-building Site Plan review
- Site Plan Application (Existing Commercial Building) submitted at least 7 days prior to a Planning Commission meeting (2nd and 4th Thursdays of the month), per the official Doc 508 packet — the form itself asks generally 'what is being proposed' and is not restricted by its own text to same-use scenarios, though its packet title reads '(Existing Commercial Building - same use, minimal remodeling)'
- A detailed site plan showing parking, landscaping, the building footprint, and the proposed floor plan for the new use/business, including restrooms, windows, and outside doors, per the Doc 508 form
- Commercial Business License Application (Doc 383), if the new use is a business — requires prior Site Plan Approval from the Planning Commission, and sign-off from both the Fire Marshal and the Building Inspector before the license issues
- Certificate of Occupancy issued by the Chief Building Official under Plain City Code §10-1-7, confirming the new use of land or the building complies with Title 10 (Zoning Regulations)
- No permit or license affecting the change of use may be issued by any Plain City official if it would conflict with the zoning title, per Plain City Code §10-1-8
Required documents
- RequiredSite Plan Application (Existing Commercial Building)Official Plain City form (Site Plan Existing Packet, revision April 2026, plaincityutah.gov/DocumentCenter/View/508); submitted at least 7 days before a Planning Commission meeting; includes a Property Owner Affidavit and Agent Authorization section requiring notarization.
