Summary
Dallas Development Code Sec. 51A-4.407 sets a hard ceiling on how much of a lot a building can cover, layered on top of the front, side, and rear yard setbacks in the same chapter. Institutional buildings in single-family, duplex, and several multifamily districts top out at 60 percent; every other use follows the percentage fixed in its own district regulations.
(a) General provisions. (1) Except as provided in Paragraph (2), in single family, duplex, townhouse, MF-1(A), MF-1(SAH), MF-2(A), MF-2(SAH), MF-3(A), MH(A), NO(A), and NS(A) districts, institutional buildings may cover a maximum of 60 percent of the lot. (2) In single family and MH(A) districts, structures used solely for child or adult care facility uses are limited to the maximum lot coverage applicable to residential structures in each district. (3) The maximum lot coverage requirements in a planned development district are controlled by the planned development district regulations. ... (c) Schedule of maximum lot coverage. (1) Except as otherwise provided in this section, a person shall not erect, alter, or convert any structure or part of a structure to cover a greater percentage of a lot than is allowed in the district regulations (Divisions 51A-4.100 et seq.). A schedule of maximum lot coverage is contained in Section 51A-4.410.
Full Breakdown
407(a)(1) caps institutional buildings in single family, duplex, townhouse, MF-1(A), MF-1(SAH), MF-2(A), MF-2(SAH), MF-3(A), MH(A), NO(A), and NS(A) districts at 60 percent lot coverage. Paragraph (a)(2) applies that same residential-structure percentage to child- or adult-care facility buildings in single family and MH(A) districts, rather than letting them use the higher institutional number. Paragraph (a)(3) removes planned development districts from the general schedule entirely: their lot coverage maximum is set instead by that PD's own district regulations. 410. 407 supplies the enforcement hook and the 60 percent institutional ceiling, not a single number that applies everywhere.
The section works together with the front, side, and rear yard setbacks in the same division (Secs. 403) and the minimum lot area and width requirements (Secs. 406), all read together to determine how much of a given lot can legally be built out.
Violations & Fines
Building or altering a structure that exceeds its district's lot coverage cap violates Chapter 51A of the Dallas Development Code. Under Sec. 51A-1.103, a knowing violation is a separate offense for each day it continues, punishable by a fine of not less than $200 and not more than $2,000, doubled for a second conviction and trebled for a third within 24 months. The city can also pursue civil enforcement or order utility disconnection until the noncompliant coverage is corrected or a variance is obtained from the board of adjustment.
