Do I need a permit for basement finishing in Post Falls?

Permit likely required

Most likely yes. Basement finishing usually requires a permit in Idaho. Confirm the specifics with Post Falls.

Idaho's amended residential energy code sets basement wall insulation at R-15 continuous or R-19 cavity in climate zones 5 and 6 (IDAPA 24.39.30.600.06.b). Idaho deletes Exception 2 of R314.2.2 and R315.2.2, which concern smoke and carbon monoxide alarms in alterations (IDAPA 24.39.30.600.03.k, l); ask the plan reviewer what alarms are required. Electrical, plumbing and HVAC work needs its own permit from DOPL or the local program even where no building permit exists (Idaho Code 54-1005, 54-2620, 54-5016). A permit cannot require upgrades to unaffected existing parts that complied with the code when built, unless the building official proves a specific substantial safety hazard (Idaho Code 39-4111(3)).
