Austin, TX Accessory Structures: Carport Rules (2026)

Carports in Austin are reviewed by the Development Services Department (DSD) under the Garage Conversion and Carport/Porch Enclosure Permit process. Because a carport is not enclosed, it does not count toward Gross Floor Area (GFA) or Floor-to-Area Ratio (FAR) under LDC Subchapter F, § 3.3, but enclosing it converts it into a garage that counts in full. For single-family residential uses, an applicant may take one 450-square-foot exemption per site for a carport or detached garage (LDC Subchapter F), which cannot be combined with the separate 200-square-foot attached-parking exemption used to meet minimum parking. Required yards must remain open from finished grade to the sky under LDC § 25-2-513, so a carport generally cannot encroach into the required side or rear yard — in SF-3 zoning the side yard is typically 5 feet under LDC § 25-2-492's site development regulation table. Permit applications must show whether any structure encroaches into a required yard and require building, electrical (if lighting is added), and zoning review.
