General Requirements
Building permits are required for new construction of any structure (residential or commercial), additions to existing structures, structural alterations, placement of manufactured/modular homes, and accessory structures above a threshold size. Fences, demolition, and placement of temporary structures may also require permits depending on type and size.
Required Documents
- Completed county building permit application form
- Site plan showing property boundaries, setbacks, structure location, and utilities
- Construction drawings (floor plan, elevations, foundation plan, framing details)
- Proof of legal access and/or road approach permit if accessing a county road
- Water supply documentation (well permit from Wyoming State Engineer's Office, or water district connection approval)
- Wastewater/septic documentation (Wyoming DEQ permit or documentation of connection to a public sewer system)
- Floodplain determination (contact Fremont County Floodplain Administrator if property is in or near a FEMA Special Flood Hazard Area)
- For manufactured/modular homes: HUD data plate, installation specifications, and foundation engineering if required
- Building code
- Fremont County has historically adopted the International Building Code (IBC) for commercial construction and may reference the International Residential Code (IRC) for residential. Wyoming has no statewide mandate to adopt a residential code, so county adoption and the specific edition in effect should be confirmed directly with the department.
- Owner-builder
- Wyoming does not require a state general contractor license, so property owners may generally perform their own construction work. An owner-builder is still required to obtain all applicable building permits and pass all required inspections. For electrical and plumbing work, licensed specialty contractors are required unless the owner-builder qualifies for an owner-occupant exemption under Wyoming Division of Labor and Wyoming Plumbing Board rules.
- Contractor requirements
- No general contractor license required at the state or county level. Electricians must be licensed through the Wyoming Division of Labor. Plumbers must be licensed through the Wyoming State Plumbing Board.
Fees
- Permit fee formula
- Fremont County building permit fees are typically valuation-based (calculated as a percentage of the estimated construction cost or by a per-square-foot table). Residential new construction typically ranges from $0.10 to $0.30 per square foot of conditioned area at a minimum, or a valuation-based formula.
- Payment note
- Fees are typically due at time of permit issuance or application; confirm accepted payment methods with the department.
Work That Does NOT Require a Permit
- Agricultural exemptions: Wyoming law generally exempts farm and ranch buildings used for agricultural purposes from building permit requirements in unincorporated areas, provided they are not used for human habitation. Confirm the specific scope of Fremont County's agricultural exemption with the department.
- Small structures: Sheds and accessory structures below a certain square footage may be exempt from building permits. The threshold varies; contact the department for the current Fremont County threshold.

How to Schedule
