Do I need a permit enclose a carport into a garage?

Friday, December 24, 2021

Yes, you need a building permit to convert a carport into a garage. The main reason is that an attached carport that becomes a garage comes under a cluster of code safety standards that are not required for a carport. The most significant is that the walls and ceiling areas that are common with the house must be continuous 1/2” drywall, or equivalent for fire resistance, and not compromised by any openings. This also means that a window from the house into the former carport is no longer acceptable. Some other code requirements are:

•• Door to house must be solid wood, or other door with minimum 20-minute fire resistance. No doggie door cut into it.

•• Garage must have a minimum of one GFCI-protected receptacle outlet. 

•• Must have at least one wall-switch controlled light.

•• If the vehicle garage door has an electric opener, the control buttons must be located within clear sight of the door and high enough to be out of reach of small children.

•• The floor should slope towards the vehicle garage door.

    Also, when you sell the home, some buyers and jurisdictions now expect proof of closed-out permits for any additions or improvements to a home in order to close a residential real estate sale. So having one is an asset.
