Who handles permitting for this jurisdiction?
Park County Planning and Zoning Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
No verified online portal was located in the reviewed public materials. Contact 307-527-8540; Powell line: 307-754-8540 and request the current application route before preparing a final submittal.
How long might review take?
The Planning and Zoning Director must approve or deny a complete Building/Zoning Permit application within 14 days. Construction must begin within one year, and a project not completed within three years requires a new permit.
How are inspections scheduled?
Park County does not conduct general building-code inspections or issue certificates of occupancy/completion. A small-wastewater installation must be inspected before backfill; arrange that inspection through Planning and Zoning at 307-527-8540 or 307-754-8540. For state electrical inspection in Park County, contact Wyoming inspector Patrick Street at 307-421-0437 after obtaining the required wiring permit. State Fire Marshal-reviewed projects have separate inspection requirements.
Which codes and exemptions should I review?
Unincorporated Park County has not adopted a building code, performs no general structural building-code inspection and does not issue certificates of occupancy or completion; it encourages reference to the International Building Code and uses IBC 2003 snow-load guidance of 20-30 psf with higher-elevation case-study areas. County Building/Zoning Permits enforce the 2025 Development Standards and Regulations. Projects within Wyoming State Fire Marshal jurisdiction are additionally governed by the state's adopted 2024 IBC, IFC, IFGC, IMC and IEBC, and the 2026 NEC is effective July 1, 2026. The County permit is a zoning/use approval rather than a structural-code permit. It is required to locate, relocate, erect or construct a building or structure; enlarge exterior dimensions; reconstruct a structure in the designated floodplain; change a building's use; increase sewage design flow through an occupancy/use change; or occupy an RV/camper more than 90 days per year. Work outside those triggers, such as ordinary interior cosmetic maintenance that does not enlarge a structure, change its use, affect a floodplain structure or increase sewage design flow, is not identified as requiring the County Building/Zoning Permit. State electrical and fire-plan-review requirements remain separate.
