Apply for a Building Permit

Thin Pic Build

Before you apply for a building permit we recommend reading the First Time Applying for a Building Permit page to familiarize yourself with our permit process. Additionally we recommend reading the Construction Documents page to get a sense of what construction documents will be required prior to permit issuance.

Projects such as new construction of a single family home, home remodels, accessory dwelling units (ADUs), re-roofs, tenant improvements, commercial, etc. require a Regular Building Permit. Some minor projects qualify for an Fast Track Permit. Simple solar projects can use the SolarAPP+ for same day permit issuance.

Special Structures. Structures such as Alternative-Owner Builder (AOB) residences, ag-exempt greenhouses, and manufactured homes should all be applied for via the Regular Building Permit process. See our First Time Applying for a Building Permit page for more information about special structures.

Please read all the instructions below before you submit for a regular building permit application.
