Austin Shed Permit: do you likely need a permit?
A small detached accessory structure may be exempt only if it stays within Austin's size, height, use, plumbing, and floodplain limits.
What the official sources say
Austin exempts a one-story detached accessory structure when it is no more than 200 square feet, no more than 15 feet high, does not create a dwelling, has no plumbing, and is not in a flood hazard area. Austin's permit type page lists new construction or additions of a shed as residential building permit work when the exemption does not apply.
Likely permit path
- Residential building permit for sheds outside the exemption or used as habitable/dwelling space.
- Trade permits for electrical, plumbing, or mechanical work.
- Zoning, floodplain, tree, or easement review depending on the lot.
Watch-outs
- Adding plumbing or converting a shed to dwelling space is a major trigger.
- Accessory structures can affect impervious cover and setback compliance.
- A flood hazard location removes the common small-shed exemption.
Documents to gather
- Site plan with shed footprint, dimensions, height, setbacks, and existing structures.
- Description of use, foundation, utilities, and whether plumbing is included.
- Photos or survey if the shed is near lot lines, easements, trees, or floodplain areas.
Questions to ask before applying
- Is the property inside city limits, an ETJ, a historic district, a floodplain, or an HOA-controlled subdivision?
- Will any electrical, plumbing, mechanical, gas, structural, drainage, or right-of-way work be included?
- Can the city confirm whether this scope is eligible for a simpler permit path or requires full plan review?
