Do I need a permit? 

Many projects and additions in and around your home require city approval. Permits are required to ensure the integrity of the work and the safety of your home. Inspections (roughs and finals) should be scheduled with our office as work progresses and when the work has been completed. Inspections protect you by verifying any finished work is safe and meets statewide statutes and city ordinances. Completing and passing final inspections is the only way to close a permit on your property.
