Full Breakdown
Under the Residential Building Permit Fees schedule at Sec. 20.04.110, a new accessory structure without utilities -- the code lists carport, deck, fence, or shed as examples -- larger than 150 square feet triggers an $85 base permit fee covering one inspection. Decks and patios must also meet the yard setbacks for Established or New Neighborhoods set out in Subsection 25.03.090.2, and ground-level decks may come within three feet of interior side and rear property lines. A structure built with utilities, such as a deck wired for outdoor power, instead falls under the higher $195 accessory-structure-with-utilities fee category.
Violations & Fines
Building a deck or patio without the required permit, or outside the setbacks in Subsection 25.03.090.2, is a municipal infraction under Sec. 25.06.160.3, carrying a $100-$750 civil fine (Sec. 1.04.100) plus a correction order.
