Twin Falls building permits and plan review
The City issues permits for new construction, additions, alterations, commercial work, trade work, pools, fences, accessory structures, signs, and other regulated projects. Twin Falls warns that work must not begin until permits are issued. The Building Safety Department publishes applications, permit information, code guidance, and current plan-review timelines for residential and commercial projects.
Residential permit applications are available through the City’s online Building Permit Portal. Use the City’s applications and forms page for commercial, residential, demolition, manufactured-home, temporary-structure, and related submittals. Check setbacks, easements, historical-preservation requirements, and zoning before submitting.
Twin Falls inspections and certificates of occupancy
Building inspections can be requested through the Cityworks portal or by calling (208) 735-7333. The City says portal requests made by 7:00 a.m. may receive same-day scheduling. Have the permit number, property address, contact information, and inspection type ready when calling.
Twin Falls requires the applicable rough and final mechanical, electrical, plumbing, fire, and building inspections before the final building inspection. The City issues certificates of occupancy in the order received and says processing can take up to three business days after required approvals.
Twin Falls zoning and development review
Planning & Zoning inspections can be reached at (208) 735-7267. Projects in the historical preservation district may require commission review before the permit is issued.

Field work & closeout
Building Inspections & Code Compliance in Twin Falls
Most permitted work must remain accessible for inspection at defined stages. Before scheduling, check your permit record for the required inspection sequence and make sure the site is safe and ready. Final inspections can be especially important for code compliance and a certificate of occupancy.
Helpful preparation
Keep the permit card or approval number available, confirm the property address, and ask the official office about lead times or reinspection fees.
Planning & review
Zoning and Plan Review Requirements
A building permit is not always the only approval your project needs. Zoning guidelines may affect use, setbacks, height, parking, signage, or lot coverage. Residential and commercial building permits can also follow different plan review tracks, so confirm the correct path before investing in a full plan set.
For a project in Twin Falls, start with the official department below and ask which zoning, planning, conservation, or fire review approvals apply to your address.
