Austin Shed Permit Guide

Austin exempts some small detached accessory structures, but size, height, plumbing, dwelling use, and flood hazard location matter.

Permit takeaway

Austin says a one-story detached accessory structure may be exempt if it is no more than 200 square feet, no more than 15 feet high, does not create a dwelling, contains no plumbing, and is not in a flood hazard area.

Zoning and placement

A permit exemption does not remove the need to comply with building codes, city codes, zoning, and other ordinances.

Building and trade review

Plumbing, dwelling use, flood hazard areas, larger sizes, and taller structures can move a shed into permit review.

Call before applying when

Call before buying if the shed is near floodplain, includes utilities, is over 200 square feet, is taller than 15 feet, or could be used as habitable space.
