Maximum Building Height for Residential Houses in the City of Dallas
Maximum building heights in the City of Dallas for single-family residences typically vary between 30 and 36 feet depending on the specific Residential District, while Agricultural and Manufactured Home districts are limited to 24 feet. In Walkable Urban districts, the Residential Transition (RTN) classification allows heights up to 35 feet, though all Dallas residential structures may be subject to further limitations imposed by the Residential Proximity Slope.
Standard Residential District Height Limits
Under the Dallas Development Code, the maximum allowable height for a residential house is determined by the specific zoning district in which the property is located. In most standard single-family districts, such as the R-7.5(A) or R-5(A) districts, the height is capped at 30 feet. Larger estate-style districts like the R-1ac(A) and R-1/2ac(A) districts allow for heights up to 36 feet [Section 51A-4.112].
| Zoning District Type | Specific District Name | Maximum Height (Feet) |
|---|---|---|
| Agricultural | Agricultural [A(A)] District | 24 feet |
| Single Family (Estate) | R-1ac(A), R-1/2ac(A) | 36 feet |
| Single Family (Standard) | R-16(A), R-13(A), R-10(A), R-7.5(A), R-5(A) | 30 feet |
| Duplex | Duplex [D(A)] District | 36 feet |
| Townhouse | TH-1(A), TH-2(A), TH-3(A) | 36 feet |
| Clustered Housing | Clustered Housing (CH) | 36 feet* |
| Manufactured Home | Manufactured Home [MH(A)] | 24 feet |
| Residential Transition | RTN District | 35 feet |
*Note: In the CH District, height may be further restricted to 26 feet if located near certain other residential districts [Section 51A-4.115(4)(E)].
Height Extensions for Vertical Projections
The City of Dallas allows certain structures located on top of a residential building to exceed the standard height limit. In any district where the building height is limited to 36 feet or less, the following items may project up to 12 feet above the maximum specified height limit [Section 51A-4.408(a)(2)]:
- Elevator penthouses or bulkheads.
- Mechanical equipment rooms.
- Cooling towers.
- Tanks designed to hold liquids.
- Ornamental cupolas or domes.
- Skylights and clerestories.
- Chimneys and vent stacks.
- Parapet walls (limited to a height of four feet).
Residential Proximity Slope Restrictions
A critical limitation on residential height in the City of Dallas is the Residential Proximity Slope (RPS). This regulation protects lower-density residential areas from the visual impact of taller nearby buildings. The slope is an imaginary plane projected upward and outward from a "site of origination" (typically a lower-density residential lot) [Section 51A-4.412].
If a building in the City of Dallas is subject to this slope, no portion of the structure may extend above that plane. The angle and extent of this protection depend on the zoning of the protected site [Section 51A-4.412(c)]:
| Site of Origination (Protected Category) | Angle of Projection | Extent of Protection |
|---|---|---|
| R, R(A), D, D(A), TH, and TH(A) Districts | 18.4° (1 to 3 slope) | Infinite |
| CH, MF-1, MF-1(A), MF-2, and MF-2(A) Districts | 45° (1 to 1 slope) | 50 feet from the site |
Multifamily Residential Height Limits
For larger residential developments in the City of Dallas, such as apartment complexes, the maximum height increases significantly with the density of the district [Section 51A-4.116]:
- MF-1(A) and MF-2(A) Districts: 36 feet.
- MF-3(A) District: 90 feet.
- MF-4(A) District: 240 feet.
