Decks over 30 inches above grade require building permits in Tuolumne County per California Building Code. Covered patios and any structure attached to the house also require permits. Snow load design is required at higher elevations.
Tuolumne County requires building permits for decks that are more than 30 inches above adjacent grade at any point, per the California Building Code. Covered patios, pergolas with solid roofs, and any structure attached to the dwelling require permits. Ground-level patios (concrete slabs at grade) generally do not require building permits but must comply with zoning setbacks. The county's mountain communities (Twain Harte, Long Barn, Pinecrest) require snow load design calculations for decks and covered structures — snow loads can exceed 40 psf at higher elevations. Deck permits include structural, connection, and railing inspections.
Deck without required permit: stop work order, retroactive permit with penalty fees. Safety deficiencies: correction notice.
