Do I need a permit for addition or structural alteration in Cedar Park?
Yes. In Texas, addition or structural alteration generally requires a permit, and Cedar Park is no exception.
Additions to a Texas home almost always require a building permit plus separate trade permits, and enclosed additions trigger full residential plan review. Outside city limits, county authority over residential building is limited, so confirm which office has jurisdiction over your property before starting. Cedar Park lists additions to existing structures among the projects that require a permit, and the city reviews residential plans against the adopted 2021 International Residential Code before issuing the permit. Additions are constrained by zoning setbacks and lot coverage; the Residential Guideline Packet lists the plans and details Cedar Park requires for submittal. Any electrical, mechanical, or plumbing work in the addition must be performed by the appropriate Texas state licensed trade contractors and inspected.
