Deck Construction · Modoc County, California
In California, a Deck Construction requires a building permit.
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit. Plans are reviewed under the Statewide (CA Codes) code (IRC 2024); apply through Modoc County Building Inspector before work begins.
