Building Permit (Sheridan County Building Standards Area ONLY)
VerifiedA true structural building-code permit under the adopted 2021 I-Codes package IS required, but ONLY for structures within the mapped 'Sheridan County Building Standards Area' (a zone around/adjoining the City of Sheridan — see Appendix A Planning Map), specific legacy subdivisions the BOCC already imposed permitting/inspection on before Dec. 5, 2006, all subdivisions approved after Dec. 5, 2006, and any structure built under a Conditional Use Permit. Outside that defined area, unincorporated Sheridan County generally has NO county building permit for private construction. COMMERCIAL SCOPE: this single permit covers COMMERCIAL construction too. In the recorded Building Standards ordinance, Article I, Sec. 3(a) applies the rules to 'all structures' in the covered areas with no commercial/residential distinction, Article III, Sec. 1 requires the permit for 'any building or structure' valued over $5,000, and the 2021 International Building Code (the commercial code) is adopted in whole under Article II, Sec. 1. Sheridan County has NO separate commercial building permit, commercial fee line, or commercial-specific process anywhere in the county — neither the ordinance, nor the county's Building in the County page, nor its Required Permits page distinguishes commercial from residential. Commercial projects OUTSIDE the covered areas get no county structural permit at all; they are governed by the countywide Zoning Permit plus, for qualifying occupancies, mandatory Wyoming State Fire Marshal fire/life-safety plan review and a state Permit to Construct under W.S. § 35-9-108 (see tips).

Requirements
- Required before construction of any building or structure valued over $5,000 (new construction, remodeling, repair, additions, or demolition) — ONLY for parcels within the mapped Building Standards Area, qualifying legacy/post-2006 subdivisions, or Conditional Use Permit structures
- All construction, regardless of value, must conform to the adopted codes if the parcel is within scope
- Codes adopted (per 'Building Standards, Sheridan County, Wyoming,' filed as County Clerk doc. #2023-785780, effective May 30, 2023, Article II and the Exhibit 1 revision table): 2021 International Building Code, 2021 International Residential Code, 2021 International Mechanical Code, 2021 International Fuel Gas Code, 2021 International Plumbing Code, 2022 National Electrical Code, 2021 International Fire Code, and the Uniform Code for the Abatement of Dangerous Buildings, plus the current International Code Council Building Valuation Data
- Farms/ranches on 40+ deeded acres, county hospitals, mines/oilfield/refinery facilities, and railway buildings/equipment are exempt from these codes even within the mapped area
- Commercial buildings are covered by this SAME permit within the covered areas — Article I, Sec. 3(a) applies to 'all structures' and Article III, Sec. 1 to 'any building or structure' over $5,000, with the 2021 IBC adopted in whole; unincorporated Sheridan County has no separate county commercial permit, application, or fee (recorded ordinance, pages 6 and 9 of County Clerk doc. #2023-785780)
- Commercial projects ANYWHERE in unincorporated Sheridan County (inside or outside the Building Standards Area) that meet W.S. § 35-9-108 thresholds additionally require Wyoming State Fire Marshal plan review and a state Permit to Construct BEFORE work begins: state/local government owned or leased buildings, schools, buildings over 5,000 sq ft total area with public access (such as a business), child care centers for more than 10 children, multi-story buildings, places of assembly regardless of size, and alterations/remodels of any of those valued at $40,000+ (per ICC Building Valuation Data) — per wsfm.wyo.gov/fire-prevention/plan-review, fetched 2026-08-01

Building Permit (Commercial New Construction, Additions, Remodels & Tenant Improvements)
VerifiedSheridan County publishes no separate commercial building permit, application, or fee. Within the mapped Sheridan County Building Standards Area (Appendix A Planning Map to Building Standards, Sheridan County, Wyoming, County Clerk doc. #2023-785780), qualifying legacy subdivisions the county already permits, all subdivisions approved after December 5, 2006, and Conditional Use Permit structures, a commercial building or structure valued over $5,000 uses the same Building Permit issued for residential construction: the ordinance applies to 'all structures' (Article I, Sec. 3(a)), requires a permit for 'any building or structure' over $5,000 (Article III, Sec. 1), and adopts the 2021 International Building Code in whole (Article II, Sec. 1) alongside the county's other 2021-2022 codes. The county's own Building & Zoning Permit Plan Submittal Requirements add one commercial-specific condition: plans for a structure intended for business, commercial, or industrial use must be designed and certified by an engineer or architect licensed in the State of Wyoming. Outside the mapped area, outside those subdivisions, and absent a Conditional Use Permit, the county issues no structural building permit for commercial construction at all; the project instead needs the countywide Zoning Permit and, for an occupancy meeting Wyoming State Fire Marshal thresholds under W.S. § 35-9-108, a separate state fire/life-safety plan review and Permit to Construct.

- Reviewed under the 2021 International Building Code, adopted in whole by Article II, Sec. 1 of the same ordinance, together with the 2021 International Residential, Mechanical, Fuel Gas, and Plumbing Codes, the 2022 National Electrical Code, and the 2021 International Fire Code, except where Article IV County Amendments specifically modify a section
- Plans for a structure intended for business, commercial, or industrial use must be designed, drawn, and certified as code-compliant by an engineer and/or architect licensed in the State of Wyoming, per the Building & Zoning Permit Plan Submittal Requirements (rev. 5/1/2026); this certification is not required of ordinary residential plans

- A plan review fee is charged in addition to the building permit fee, set at 47 percent of the building permit fee per the Land Use Fee Schedule (adopted June 6, 2023) — within the up-to-67-percent ceiling Article IV sets for the amended 2021 IBC Section 109.3
- Farms and ranches on 40 or more deeded acres, county hospitals, mines and oilfield/refinery facilities, and railway buildings are exempt from these codes even within the mapped area, per Article I, Sec. 3(b)

Solar PV Permit
VerifiedSheridan County has no dedicated solar permit or fee category. A residential rooftop or ground-mounted PV installation is processed under the same baseline Zoning Permit ($150) required countywide for any new construction or accessory structure, verifying setbacks and zoning-district compliance — no solar-specific accessory-use classification or setback distance was found published in the county's zoning materials. A true structural building-code permit additionally applies ONLY if the parcel falls within the mapped Sheridan County Building Standards Area (near the City of Sheridan), a pre-2006 legacy subdivision the county already permits, a post-2006 subdivision, or a Conditional Use Permit structure — otherwise the county has no structural building-code review at all for private construction. Electrical interconnection is handled by the Wyoming State Fire Marshal's Office (WSFM) — Dept. of Fire Prevention & Electrical Safety, not the county, per the same statewide mechanism documented in this jurisdiction's Electrical Permit entry.

EV Charger / EVSE Permit
VerifiedUnincorporated Sheridan County does not run its own electrical inspection program — electrical wiring permits are issued by the Wyoming State Fire Marshal's Office (WSFM), Dept. of Fire Prevention & Electrical Safety, under W.S. § 35-9-119, confirmed by the county's own Zoning Permit application, which routes new electrical work to the state program. An EV charger/EVSE installation therefore requires a State of Wyoming Electrical Wiring Permit through WSFM, not a county permit. WSFM publishes no distinct EV charger/EVSE fee line; a residential EVSE circuit is billed under the same standard wiring permit and residential service inspection fee structure used for all electrical work.

Sign Permit (WYDOT Outdoor Advertising Permit — no county-level sign permit)
Sheridan County's own official Required Permits page (which lists only Building & Zoning, Driveway, Septic, and Flood Plain permits) and its Land Use Fee Schedule (adopted Oct. 4, 2011) contain no county-issued sign permit or sign-specific fee line. A sign large enough to qualify as new construction or an accessory structure would fall under the same baseline countywide Zoning Permit ($150, documented in this jurisdiction's Zoning Permit entry). The one confirmed, distinct sign permit that DOES apply is the Wyoming Department of Transportation (WYDOT) Outdoor Advertising Permit, a state-level permit required for off-premise advertising signs (billboards) visible from a state highway or interstate — separate from, and not administered by, Sheridan County.

Installation, addition, or alteration of a fire alarm, fire sprinkler, fire suppression, or special hazard system anywhere in Wyoming — including unincorporated Sheridan County — is permitted and inspected by the Wyoming State Fire Marshal's Office (WSFM), Dept. of Fire Prevention & Electrical Safety, the same state agency that runs the electrical wiring permit program already documented in this jurisdiction's Electrical Permit entry.

Requirements
- State of Wyoming fire protection system plan review and Permit to Construct required through WSFM for installation, addition, or alteration of a fire alarm, fire sprinkler, fire suppression, or special hazard system — required 'regardless of size or valuation' per WSFM's Plan Review program page
- Apply through the WSFM eLicensing, ePermit, and ePayment Portal
- Plans are accepted or rejected within 5 business days of receipt
- Complete submittals are reviewed within 21 further business days of acceptance; if WSFM requests additional information, review completes within 10 business days of receiving it or the original 21-day window, whichever is later
- Review fees are calculated from the fee schedule in Dept. of Fire Prevention & Electrical Safety Rules, Chapter 2, Section 3; the applicant is notified of the exact fee once plans are accepted, and payment is due before the Permit to Construct is issued
- Upon completion and passing of all required inspections, WSFM issues a Certificate of Occupancy or Letter of Compliance
- None of the six rural fire protection districts serving unincorporated Sheridan County administer their own sprinkler/alarm permitting or plan review — confirmed on Sheridan County's own Fire Protection Districts page, which lists only district governance/meeting contacts, not a permitting function

Change of Use / Certificate of Occupancy
VerifiedSheridan County does not operate a separate, standalone 'change of use' permit or issue its own Certificates of Occupancy for private construction. The county's own official Required Permits page folds change of use directly into the existing Building Permit & Zoning Permit line item — 'Construction of any new building, or addition to, or change of use of existing building' — meaning a change of use is processed through the SAME Zoning Permit ($150, documented in this jurisdiction's Zoning Permit entry) required countywide for new construction, or through the Building Permit (documented in this jurisdiction's building-permit-limited-area entry) if the parcel falls within the mapped Building Standards Area, a qualifying subdivision, or a Conditional Use Permit structure. Where a true Certificate of Occupancy or Letter of Compliance IS issued for a structure in unincorporated Sheridan County — i.e. one subject to Wyoming State Fire Marshal fire/life-safety plan review, such as a public building or a structure with a permitted fire alarm/suppression system — WSFM itself issues that certificate upon completion and passing of all required inspections, the same state mechanism documented in this jurisdiction's Fire Sprinkler/Alarm Permit entry.

Requirements
- No standalone 'change of use' permit exists in unincorporated Sheridan County — per the county's own Required Permits page, a change of use of an existing building is processed under the same Building Permit & Zoning Permit line item used for new construction
- Where the parcel is OUTSIDE the mapped Building Standards Area (the large majority of unincorporated Sheridan County), a change of use is processed through the baseline Zoning Permit ($150) — same requirements, plot plan, and proof of ownership documented in this jurisdiction's Zoning Permit entry
- Where the parcel is INSIDE the mapped Building Standards Area, a qualifying pre-2006/post-2006 subdivision, or a Conditional Use Permit structure, a change of use is instead processed through the county Building Permit documented in this jurisdiction's building-permit-limited-area entry
- Sheridan County does not itself issue a separate 'Certificate of Occupancy' document for ordinary private construction — no such form or process is published on the county's Required Permits page, Building in the County page, or Land Use Fee Schedule
- Where a Certificate of Occupancy or Letter of Compliance IS issued in unincorporated Sheridan County, it is issued by the Wyoming State Fire Marshal's Office upon completion and passing of all required fire/life-safety plan-review inspections — applicable to public buildings and structures with a permitted fire alarm/sprinkler/suppression system, per WSFM's Fire Prevention program page
Required documents
- RequiredSheridan County Zoning Permit Application (revised 5/1/2026)Used for a change of use with no new construction outside the mapped Building Standards Area — same form documented in this jurisdiction's Zoning Permit entry
- OptionalBuilding App & Submittal Requirements (rev. 5/1/2026)Used instead for a change of use within the mapped Building Standards Area, a qualifying subdivision, or a Conditional Use Permit structure — same form documented in this jurisdiction's building-permit-limited-area entry
Fee schedule
| Fee type | Amount | Notes |
|---|---|---|
| Change of use fee | No distinct fee — billed as a Zoning Permit ($150.00) or, within the mapped Building Standards Area, as a Building Permit | Sheridan County Land Use Fee Schedule (adopted Oct. 4, 2011) lists only a single 'Zoning Certificate' fee ($150.00) plus the separate Building Permit valuation table; no distinct change-of-use or certificate-of-occupancy line item exists. |
