Kailua carports must follow city-wide dimensional standards capping horizontal size at 20 feet by 20 feet, with limited hillside exceptions for Type V-B construction.
ROH Sec. 21-2.140-1 sets specific rules for carport and garage dimensions on Oahu. Maximum horizontal dimensions are 20 feet by 20 feet. On hillside lots, a carport of Type V-B construction may exceed one story when specified conditions are met, which can matter for Maunawili and Aikahi Park hillside parcels. Setbacks from ROH Sec. 21-4.30 and height limits from Sec. 21-4.60 apply in addition to these dimensional rules. Carports attached to or replacing garages also interact with ADU rules under 21-5.720 if enclosed for habitation.
Carports exceeding size limits or failing setback and height rules may be required to be modified or removed and can incur fines.
