Finishing a Basement or Interior Renovation

Your finished basement or interior alteration requires permits and inspections in order to ensure that it is safe for your enjoyment. We encourage you to review our compliance guidelines for finished basements before applying for a permit.

Permits Required

Your finished basement or interior alteration will require a building permit, and if wired with electricity, an electrical permit. If new plumbing elements will be installed, a plumbing permit will also be required. Please gather the construction documentation specified below and submit a building permit application. After the building permit is filed, have your licensed electrician submit an electrical permit application and/or have your licensed plumber submit a plumbing permit application.

Permit Process
Many factors affect the speed with which your application(s) are approved. For best results, it is critical that you carefully review your application and design documents prior to submission to ensure that all necessary documents are included and that the design is compliant with the county code. Normally, permits can be issued within 10-15 business days if the application is complete, accurate, and code-compliant.

Construction Document Requirements

Submitted documents must contain sufficient information for the plan reviewer to be able to review the proposed construction.
