Since 1931, all residential buildings in Austin have been required to have a Certificate of Occupancy (CO) for its current use. Sometimes a homeowner discovers their property does not have a CO on record, in which case a new one (known as an Amnesty Certificate of Occupancy) must be obtained. If your property qualifies for an Amnesty CO, the application can be found in Residential Building Review’s forms and applications, which can be found here along with their location and hours of operation. Submit a complete application package to Residential Building Review during general information walk-in hours. If you do not meet the requirements (your house was built after 1986), then you must reenter the permitting process to obtain a new CO. Looking to get a CO for a non-residential property? Your process will begin with the Development Assistance Center (DAC).
