Cobb County, GA Short-Term Rentals: Short-Term Rental Parking Rules (2026)

Cobb County treats short-term rental parking as an extension of its standard single-family occupancy rule, not a separate STR-only cap. Code section 78-407(h)(3)-(4) directs owners to section 134-1's definition of 'single-family dwelling unit' for occupancy and parking, and to section 134-272 for off-street parking. Section 134-1 sets the numeric cap: no more than one vehicle per 390 square feet of the home's living building square footage, as recorded by the Cobb County Tax Assessor, may be parked regularly overnight on the property, counting vehicles left in the adjacent right-of-way.

'Regularly' is defined as a majority of days in any seven-day period, so the rule targets a standing overnight pattern rather than a single busy weekend. Of that total, zoning determines how many vehicles can sit outside a garage or carport: a maximum of four in the PRD, OSC, RA-5, R-15, R-20 and R-30 districts, a maximum of five in R-40, R-80 and RR, and four in any other single-family zoning district. Separately, section 134-272's off-street parking table requires two spaces per dwelling unit for both attached and detached single-family units, a baseline every STR must still provide regardless of guest count.

An owner seeking relief from the vehicle-count cap can request an exception through a land use permit processed under section 134-36. 00 certificate from the business license division, and the application must list the number and location of parking spaces allotted to the property. Because these standards come from the general zoning code rather than a rental-specific ordinance, they apply the same way to any single-family home in unincorporated Cobb, rented short-term or not; the certificate program is what ties enforcement specifically to STR operators.
