Permit checklist for building in Las Vegas and surrounding towns

Requirements differ town by town. Use this checklist with your local building, zoning and health departments, and include what you learn in your design instructions. We'll draw to it.

1. 01Find who issues permitsIncorporated towns and cities usually have a building department. In unincorporated areas it's the county building or planning office, or a state agency, or in some rural areas nobody. Call before you buy the lot.
2. 02Zoning & setbacksCheck the zoning district for minimum lot size, front, side and rear setbacks, maximum height, lot coverage and whether barndominiums, ADUs or metal buildings are allowed.
3. 03HOA & deed restrictionsSubdivisions often restrict minimum square footage, exterior materials, roof pitch, garage orientation and outbuildings. These can be stricter than the town code.
4. 04Septic & well permitsWithout city sewer or water, you'll need a percolation (perc) test and a septic permit from the county health department, plus a well permit.
5. 05Driveway & culvert permitConnecting to a public road usually needs a driveway or culvert permit from the town, county or state DOT.
6. 06Floodplain development permitIf any part of the lot is in a FEMA flood zone, you'll need a floodplain permit and an elevation certificate, and the lowest floor must be at or above the Base Flood Elevation plus any local freeboard.
7. 07Energy code complianceMost jurisdictions require an energy compliance report (REScheck or similar) showing insulation, windows and HVAC meet the adopted energy code.
8. 08Engineering stampMany building officials require a licensed engineer's seal for foundations, beams, trusses, or high wind, snow or seismic zones. Add our Engineer Stamp option at checkout.
