Plain City building permits

Plain City, Utah — as published 2026-08-25.

Reviewed 2026-07-23 · Source

Codes adopted

International Building Code (IBC) — adopted per Plain City Code § 9-1-1(A) pursuant to Utah Code Annotated § 58-56-4(2) and Utah Administrative Code R156-56-701, as modified by chapter 11 of the supplement to the IBC promulgated by the International Code Council, and amended per statewide amendments in Utah Administrative Code R156-56-704 (automatically updated per § 9-1-1(C) whenever the Division of Occupational and Professional Licensing/Uniform Building Code Commission adopts new statewide amendments). Per Utah Code § 15A-2-103, the statewide-adopted edition is the 2024 IBC (including Appendices C and J), which took effect July 1, 2026 and supersedes the prior 2021 IBC edition (effective July 1, 2023 through June 30, 2026) — Plain City's automatic-adoption clause carries this forward without any local ordinance action required.International Residential Code (IRC) — adopted by reference within IBC standards per Plain City Code § 9-1-1(A) ('...together with standards incorporated into the IBC by reference, including...the international residential code (IRC) promulgated by the International Code Council'). The statewide-adopted edition is the 2021 IRC per Utah Code § 15A-2-103; the 2026-07-01 statewide IBC transition to the 2024 edition did NOT carry the IRC forward, so 2021 remains current.International Energy Conservation Code (IECC) — adopted by reference within IBC standards per Plain City Code § 9-1-1(A). Utah Code § 15A-2-103(1)(h) specifies the current statewide-adopted edition as the 2024 IECC. Plain City's Residential Building Permit Plan Submittal Requirements (Doc 475) additionally requires a REScheck energy analysis report showing compliance with the model energy code, passing by a minimum of 3% if using the Utah Energy Conservation Method.Statewide plumbing, mechanical, and electrical codes (IPC/IMC/NEC) apply uniformly across Utah municipalities under the State Construction Code (Utah Code Title 15A), and Plain City's own municipal code does not separately codify them. Plain City's plan submittal checklists (Docs 475, Accessory Building Doc) require electrical, plumbing, and mechanical plans as part of the IRC-governed construction drawings, consistent with statewide adoption rather than a distinct local ordinance.

Permit types & fees

Residential Building Permit

Verified

Required 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); the actual governing fee mechanism is Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE,' which 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 that governs the Solar PV, Fire Sprinkler, and Fire Alarm Permit entries — see the fees array for the full table.

A residential building permit under the currently adopted IBC is squarely 'authorized in the IBC', and it is the base building permit that the Solar PV and Fire Sprinkler/Fire Alarm entries route through, so § 9-1-4 governs here too. 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 — check the code, not only the fee resolution. Because 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.

Required 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

Verified

Required 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; instead — as with the Residential Building Permit 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 — see the fees list for the full table.

That text is not scoped to residential-only construction — a commercial/non-residential building permit under the currently adopted IBC (Utah Code § 15A-2-103) is equally 'authorized in the IBC.' The same fee mechanism governs the Solar PV Permit and Fire Sprinkler/Fire Alarm entries. It applies 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 project valuation varies, no single base-permit dollar figure applies — submit your estimated valuation to the Building Department at (801) 731-4908 for the calculated figure.

Commercial Tenant Improvement / Tenant Finish Permit

Verified

Required 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). The base building-permit fee for this scope of work is governed by Plain City Municipal Code § 9-1-4 (Table 1-A of the 1997 Uniform Building Code) — the same mechanism as the jurisdiction's other building-permit fees — see the fees array for the full table.

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)

The Resolution 2024-07 fee table is genuinely a single page (every line item, Monthly Service Fees through RV Temporary Occupancy Permit) with no Sign Permit or general Building Permit valuation-fee line item at all, and Plain City's Forms/Applications/Fees page publishes no separate building-permit valuation fee table. Plain City does not contract building/sign permitting to Weber County (as some smaller Weber County cities do, e.g. Riverdale for some services): Plain City Code § 9-1-3 establishes an in-house process — the application is forwarded from the City Recorder to the city's own Building Inspector, who returns plans within 10 days — so no county fee schedule applies. The city's alternate/mirror domain, plaincityutah.org (same CivicPlus-family platform), including its own 'Building' page, matches the.gov site with no additional or different fee-schedule PDF. The City Council's January 15, 2026 regular meeting minutes include a Planning Commission report item, 'A site plan was reviewed for a sign for Sunflower Assisted Living,' but record no fee amount, resolution, or dollar figure anywhere in the document. The only fee documents published on the city's domain are the Resolution 2024-07 Fee Schedule and an unrelated Parks & Facilities Reservation Fees document; no separate sign or building valuation fee document exists. The § 9-1-4 fee mechanism (Table 1-A of the 1997 UBC, which governs the Residential, Commercial, Tenant-Improvement, and EV-Charger Building Permit fees) does not transfer cleanly to sign permits: § 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'), which states only that the Council 'may, by resolution, prescribe fees,' with no dollar figure or cross-reference to Table 1-A. Plain City's Forms & Applications page (plaincityutah.gov/1308/Forms-Applications) lists no standalone 'Sign Permit Application' document among its ~35 forms — there is no distinct sign-permit intake with its own printed fee — and § 10-1-6 ('Building Permit'), the Title 10 zoning-title permit-requirement section adjoining the sign code, 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. The current sign-specific fee amount is unpublished; confirm it directly with the Plain City Building Department.

Solar PV Installation Permit

Verified

Plain 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. The actual governing fee mechanism sits in the municipal code instead: 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.

Plain City Municipal Code § 9-1-4, 'FEE SCHEDULE' (Title 9, Chapter 1, Building Code; Show full citationHide 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, which is issued as a standard Building Permit) — it is not restated in the city's standalone Consolidated Fee Schedule (Resolution #2024-07), which is why that document alone shows no line item; the two documents govern different things. 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) match 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 confirmed and cited rather than 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

Verified

Plain 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. Plain City's Fee Schedule (Resolution #2024-07, Exhibit A) contains no 'EV,' 'electric vehicle,' or 'EVSE' mention anywhere in the document, and no base building-permit fee is restated there at all. 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.

Fire Sprinkler System Permit

Verified

Plain 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 record), 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 record — 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).

Change of Use / Certificate of Occupancy Permit

Verified

Plain 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 the 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 record, 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.
