Residential Building Permits

Header Image

Residential building permits cover projects involving one- and two-family dwellings. (See commercial building permits for projects involving multifamily-residential buildings that contain more than two residential units.)

Before you begin any construction project, check with us to see if a permit is required. In general, construction projects where a building or structure is erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished require a permit.

We also offer an Earthquake Home Retrofit Program to assist you in upgrading the structural safety of your wood-framed house.

Examples of projects that require a building permit include:

  • Building a new house
  • Adding on a deck that is taller than 30 inches above grade
  • Enclosing a carport or garage
  • Changing the pitch of a roof
