Building a Deck

Quick Reference

Deck construction is considered an addition to a home and therefore requires permits and inspections in order to ensure that it is safe for your enjoyment. We encourage you to review our compliance guidelines for decks before applying for a permit. Other documents you might find helpful include our examples of a deck cross section, deck floor framing, deck cross section with shed-type roof, a front view of a deck with a shed-type roof, a deck cross-section with a gable roof, and deck floor framing with a gable roof.

Permits Required

Your deck will require a building permit. If your deck will feature a hot tub, spa, or other permanent electric-powered component, you will also need an electrical permit. If your deck will feature running water, such as for a sink, or gas piping to feed a gas line directly into a grill, you will also need a plumbing/gas permit. Please gather the construction documentation specified below and submit a building permit/zoning application and an owner / contractor affidavit. After the building permit application is filed, if applicable, 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.

Building Inspections
