Do I need a permit for shed or accessory structure in Austin?
It depends. Whether shed or accessory structure needs a permit in Austin comes down to the details of your project.
Many Texas cities exempt small accessory buildings. Dallas, for example, exempts a utility building under 200 square feet with no electrical, plumbing, or gas on single-family or duplex premises, but running utilities to a shed or exceeding the size threshold triggers a permit. Zoning setbacks and easement restrictions still apply even when a building permit is not required, so verify placement with your local building department. Austin lists accessory structures no more than 200 square feet of floor area and no more than 15 feet in height as work exempt from a building permit; a shed larger or taller than that generally needs a building permit and site plan review. Even an exempt shed must respect impervious cover limits and the tree ordinance: within the inner half of a protected tree's critical root zone no cut or fill greater than 4 inches is allowed, and at least 50 percent of the ground in the full critical root zone must stay undisturbed. Any power or water to the shed requires separate trade permits pulled by registered contractors through the Austin Build + Connect (AB+C) portal. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured.
