Residential Remodel, New, and Addition

What is it?

You need a New Residential or Addition Permit to build a new home or duplex or add to an existing home or duplex. This permit is for the creation of one or two family dwelling units that are attached and reside on the same lot or share detached and share the same parcel number. This permit type is also for detached single family homes having its own parcel number.  New structures that are accessory to a home, such as carports or gazebos, are considered residential accessory structures. Permits for these are required when they have a roof area over 200 square feet in size.
Examples of projects that require a New Residential or Addition Permit:
  • Construction of a new Single Family House.
  • An addition involving changes to the building square footage, whether or not this adds interior or exterior floor area
  • Converting a garage or covered porch into a living space and/or converting a crawl space to living area  

How Much Does it Cost?

Fees are based on the value of your project. You pay a plan review fee when you submit your plans and the rest when you pick up your permit. Use our fee estimator to estimate how much your permit will cost; there may be Capital Facility Charges and Impact Fees on these permit types. See the Fee Schedule (A-Z) page to download the Residential Fee Schedule for fee related information.

How Long Does It Take?

We try to finish our initial review of new and additions permit in 21 calendar days from submittal. The time it takes to issue the final permit depends on how complex your project is and how many corrections, if any, you may need.
