RESIDENTIAL CONSTRUCTION – Frequently Asked Questions
WHY do I need a permit?
When you obtain the proper permits for your construction work, you are protecting your home and family. The City of Nampa wants to ensure that your home is structurally sound, free of fire hazards and safe to occupy. Requiring permits provides a permanent record of the work performed and the inspections conducted on the project.
Homeowners are encouraged to request a conference with the inspector before starting work.
Can I do the work myself?
Homeowners may apply for building, mechanical, electrical or plumbing permits on their primary or secondary residence without registering as a contractor with the State of Idaho if you plan on living in the residence within 12 months after completion of the project. The owner must self perform all work under a homeowner's permit. If you’re not performing the work yourself (such as building, electrical, plumbing and mechanical work), the contractor performing the work must be a State of Idaho registered building contractor or a licensed sub-contractor in that trade and must pull permit a permit and perform the work.
Homeowners should require that contractors working for them obtain all necessary permits for the job.
