All districts
One-, two-, and multiple-family dwellings need 2 parking spaces per unit; dwellings in the Central Business District need 1.5 per unit (§ 770-107). No off-street parking is required in the CBD except for residential, hotel, and institutional uses (§ 770-106E).
- For one- and two-family homes, parking goes in the side or rear yard on the same lot. The specified front-yard driveway layouts require an Engineering Department permit: a horseshoe driveway (lot at least 60 feet wide, front yard 35 feet deep and 2,100 square feet) or a T-shaped driveway (lot at least 50 feet wide, front yard 30 feet deep and 1,500 square feet, with the street-parallel T appendage at least 15 feet from the front lot line) (§ 770-105F(1)).
- One driveway per dwelling, at least 8 feet wide, hard surfaced. Gravel is prohibited. Surfaces must be asphalt, concrete, or approved pervious or permeable pavement; loose aggregate, gravel, stone, unreinforced grass or sod, and soil are all prohibited (§ 770-109A). Ribbon driveways may be allowed with hard-surfaced wheel tracks 2-3 feet wide, overall outside-edge width 8-10 feet, and reinforced turf median no wider than 4 feet (§ 770-105F(1)(c)).
- A standard space is 9 by 20 feet at 90 degrees, with a 20 foot two-way aisle (§ 770-109F).
- Commercial headline ratios: retail 1 per 250 square feet usable, offices 1 per 225, restaurants and bars 1 per 65, medical 1 per 200 (§ 770-107).
- One commercial vehicle up to 6,000 pounds, owned by an occupant, may be kept per dwelling unit (§ 770-28).
Section 770-105C separately allows the Planning Commission to permit parking within the front setback when no reasonable alternative exists. That is a property-specific discretionary approval, not an automatic exception.
