Quick answer
Do You Need a Site Plan for a Permit in Idaho?
Yes, most building permits in Idaho need a site plan: a scaled drawing of the lot, existing buildings and the new work, with distances to the property lines. In Idaho, cities issue building permits inside their limits and the county issues them in unincorporated areas. Your address decides which office reviews your plans. We check that office’s requirements before quoting.

- Snow loadsMountain and northern parts of Idaho carry heavy ground snow loads, which drive roof design for garages, carports, sheds and covered porches. Large spans may need an engineer.
- Earthquake designParts of Idaho fall in higher seismic design categories, so foundations, retaining walls and additions can draw extra structural review.
- Wildfire-risk areasHomes near wildland in Idaho may be in wildfire-risk zones, where defensible space, vents and noncombustible materials can be checked.
- Deep frost linesCold winters push frost deep into the ground in Idaho, so deck, porch and garage footings must reach below the frost depth your county sets.
