Small ground-level decks and patios in Sacramento County may be exempt from permits under certain conditions. Elevated decks over 30 inches above grade require building permits. Guardrails are required on decks 30+ inches above grade.
Under the California Building Code as adopted by Sacramento County, certain decks are exempt from building permits: those under 200 square feet, less than 30 inches above the adjacent grade, not attached to the dwelling, and not serving a required exit door. Concrete patios at grade level generally do not require permits. Elevated decks exceeding any of these thresholds require a building permit with construction drawings showing structural details. Guardrails are required when the deck surface is 30 or more inches above the adjacent grade, and must be at least 42 inches high under the current California Building Code. Deck footings must comply with structural requirements and setback regulations for the property's zoning district. The Sacramento County Building Permits and Inspection Division handles permit applications, which can be submitted at their offices. Plans may need to be prepared by a licensed architect or engineer for larger or more complex deck projects. Covered patios and pergolas may have additional requirements depending on the size and whether they are attached to the house.
Unpermitted elevated decks are building code violations subject to retroactive permitting or removal. Missing guardrails on elevated decks are safety violations. Setback violations are zoning enforcement matters. Covered structures without permits may receive stop-work orders.
