Location and Design Requirements in Dallas
The City of Dallas enforces strict placement regulations for all off-street parking within the R-1ac(A) District to preserve the residential character of the neighborhood.
Ground Level Restrictions
In the R-1ac(A) District, all off-street parking must be provided at or below ground level [Section 51A-4.112(a)(5)]. This prevents the construction of elevated parking structures that would be inconsistent with the low-density estate nature of the R-1ac(A) District.
Setbacks and Placement
For residential projects in the R-1ac(A) District, all required off-street parking must be located behind the required front building line [Section 51A-4.301(a)(4)(F)(ii)]. Additionally, the Dallas Development Code prohibits the placement of any off-street parking within a defined visibility triangle [Section 51A-4.301(a)(8)].
Surface and Maintenance
The City of Dallas requires that the surface of a parking space or driveway for a single-family use in the R-1ac(A) District consist of an all-weather and drainable material approved by the building official [Section 51A-4.301(d)(3)]. Owners are responsible for maintaining these areas free of potholes [Section 51A-4.301(d)(6)].
Special Exceptions and Reductions
In certain circumstances, the Dallas Board of Adjustment may grant relief from these standards.
- Handicapped Exceptions: The board may grant special exceptions to the Dallas Development Code regulations to ensure that handicapped persons have equal opportunity to use and enjoy a dwelling [Section 51A-1.107].
- Tree Preservation: The number of required off-street parking spaces may be reduced by one for each protected tree retained on a building site in the R-1ac(A) District, up to a maximum reduction of 10 percent [Section 51A-4.312].
- Contiguous Residential Rules: If a nonresidential use in the R-1ac(A) District is contiguous to a single-family use, the minimum off-street parking requirements listed in Table 1.1 of the code may apply [Section 51A-4.301(a)(2)(B)].
