Do I need a permit for addition or structural alteration in Lakeway?
Yes. In Texas, addition or structural alteration generally requires a permit, and Lakeway 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. Lakeway lists Addition and Alteration as permit types on its building permit application, and staff review residential plans against the adopted 2021 International Residential Code before issuing the permit. An addition that adds impervious cover is constrained by Lakeway's 60 percent residential impervious cover limit and may trigger site development review; work over 2,000 square feet of added impervious cover moves beyond the small project permit. Any electrical, mechanical, or plumbing work in the addition must be performed by the appropriate Texas state licensed trade contractors and inspected.
