Front Yard Regulations for R-1ac(A)
The minimum front yard in the Dallas R-1ac(A) Single Family District is 40 feet [Section 51A-4.112(a)(4)(A)]. This measurement is taken from the front lot line of the building site or the required right-of-way as determined by the Dallas thoroughfare plan, whichever creates the greater setback [Section 51A-4.401(a)(2)].
Specific allowances and restrictions for the R-1ac(A) Single Family District include:
- Projections: Ordinary projections of window sills, belt courses, and cornices may project up to 12 inches into the required front yard. Fireplace chimneys may project up to two feet [Section 51A-4.401(a)(1)].
- Corner Lots: If a corner lot in a Dallas single family district has two street frontages of equal distance, one frontage is governed by the 40-foot front yard regulation, and the other is governed by the side yard regulations. If the frontages are of unequal distance, the shorter frontage is treated as the front yard [Section 51A-4.401(b)(1)].
- Blockface Rule: If a blockface is divided by two or more zoning districts, the front yard for the entire blockface must comply with the requirements of the district with the greatest front yard requirement [Section 51A-4.401(a)(6)].
Side Yard Regulations for R-1ac(A)
The minimum side yard for single family structures in the Dallas R-1ac(A) Single Family District is 10 feet. For any other structure permitted in the district, the minimum side yard increases to 20 feet [Section 51A-4.112(a)(4)(B)].
The Dallas Development Code provides a specific flexibility option for single family districts: one required side yard may be reduced below the 10-foot minimum if the opposite side yard on the same lot is increased to at least double the required amount (20 feet). However, the distance between structures on contiguous lots must still meet the minimum requirements of the R-1ac(A) district [Section 51A-4.402(b)(1)].
Rear Yard Regulations for R-1ac(A)
The minimum rear yard for single family structures in the R-1ac(A) Single Family District is 10 feet. All other structures permitted within the district must maintain a 20-foot rear yard [Section 51A-4.112(a)(4)(B)]. Similar to front and side yards, certain architectural features like roof eaves and balconies may project up to three feet into the required rear yard [Section 51A-4.403(a)(1)].
