Cedar Park FAQ
Can I put one of those metal-frame fabric carports in my driveway?
No. Cedar Park Chapter 11 expressly prohibits 'temporary, pre-assembled, or assembled on-site' carports in every zoning district. Even short-term placement to protect a vehicle is a code violation and Code Enforcement can require it removed.
How tall can a permitted carport be?
A permanent carport or porte-cochere may not exceed one story or twenty (20) feet in height, whichever is less. Anything taller requires a variance through the Zoning Board of Adjustment.
Do I need a permit to build a carport attached to my house?
Yes. Any permanent carport — attached or detached — requires a building permit from the Development Services Department, must match the architectural character of the principal dwelling under Cedar Park's design standards, and may not encroach into required setbacks.
Round Rock FAQ
Can I put a carport in my front yard or driveway in Round Rock?
No. Round Rock explicitly prohibits accessory structures, including carports, in front yards or over driveways in front of the home. Carports are only allowed in side or rear yards.
How tall can my carport be?
The maximum height for any accessory structure is 15 feet 0 inches, measured from existing ground level to the highest point of the roof.
Do I need a permit?
Yes. Submit an Accessory Structure building application to the Round Rock Building Inspection Office. Any associated electrical, plumbing, or mechanical work goes on the same permit.
