The Risk of Skipping Permits

Unpermitted work is discovered most often during real estate transactions. Title searches and home inspections increasingly flag unpermitted additions. Buyers can demand the work be legalized (expensive after the fact) or walk away. Some lenders won't finance homes with known unpermitted work.

How Austin Permits Work

Submit permit applications through Austin's Development Services Department portal. Licensed contractors typically pull their own permits — if your contractor says you should pull it yourself, that's a red flag.
