Dallas City Code § 51A-4.401 MINIMUM FRONT YARD.

SEC. 51A-4.401. MINIMUM FRONT YARD. (a) General provisions. (1) Required front yards must be open and unobstructed except for fences and light poles 20 feet or less in height. Except as otherwise provided in this section, ordinary projections of window sills, belt courses, cornices, and other architectural features may not project more than 12 inches into the required front yard. A fireplace chimney may project up to two feet into the required front yard if its area of projection does not exceed 12 square feet. Cantilevered roof eaves and balconies may project up to five feet into the required front yard. (2) The front yard setback is measured from the front lot line of the building site or the required right-of-way as determined by the thoroughfare plan for all thoroughfares, whichever creates the greater setback. On minor streets, the front yard setback is measured from the front lot line of the building site or the existing right-of-way, whichever creates the greater setback. When the city council by ordinance establishes a specific right-of-way line for a street, the front yard setback is measured from that right-of-way line. (3) If a building line that is established by ordinance requires a greater or lesser front yard than prescribed by this section, the building line established by ordinance determines the minimum required front yard. (4) The building official may approve a ramp that projects into the required front yard to allow a handicapped person access to an existing single family, duplex, or handicapped group dwelling unit use. The ramp must be constructed with minimal encroachment and must be constructed to the applicable accessibility standard as determined by the building official. Initial review of a complete permit application for a ramp must be completed in 10 days. (5) If a lot runs from one street to another and has double frontage, a required front yard must be provided on both streets. If access is prohibited on one frontage by plat or by the city, the following structures or portions of structures in the yard along that frontage are governed by the rear yard regulations in Section 51A-4.403: (A) Swimming pools. (B) Game courts. (C) Fences. (D) Garages. (E) Accessory storage buildings. (6) Except as provided in this paragraph, 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. (A) If the greatest front yard is in a district with only one or more of the following uses being conducted as a main use and having a minimum of 80 feet of frontage, the blockface terminates at the boundary of that use: (i) Utility and public service uses listed in Section 51A-4.212. (ii) A railroad right-of-way. (iii) A cemetery or mausoleum. (iv) Recreation uses listed in Section 51A-4.208. (B) In this section BLOCKFACE means: (i) the distance along one side of a street between the two nearest intersecting streets; (ii) where a street deadends, the distance along one side of a street between the nearest intersecting street and the end of the deadend street; or (iii) where a street centerline contains a change of direction greater than 45 degrees, the distance along one side of a street between either the nearest intersecting street or the deadend and the point determining the angle of the change of direction. (7) Reserved. (8) The minimum front yard requirements in a planned development district are controlled by the planned development district regulations. (9) In an A(A), multifamily, MH(A), office, retail, CS, LI, IR, IM, central area, mixed use, or multiple commercial district, the board of adjustment may allow a special exception from the front yard requirements of this section to permit the erection of a permanently constructed porte-cochere, covered walkway, or canopy if the structure is rectilinear in shape and does not exceed 25 feet in width at the building line, and if the board finds that the structure will not adversely affect neighboring property. (b) Front yard provisions for residential districts. (1) If a corner lot in a single family, duplex, or agricultural district has two street frontages of equal distance, one frontage is governed by the front yard regulations of this section, and the other frontage is governed by the side yard regulations in Section 51A-4.402. If the corner lot has two street frontages of unequal distance, the shorter frontage is governed by this section, and the longer frontage is governed by side yard regulations in Section 51A-4.402. Notwithstanding this provision, the continuity of the established setback along street frontage must be maintained. (2) Reserved. (3) If a TH or TH(A) district abuts another residential district in the same blockface and fronts on the same side of the street, the residential district with the greater front yard requirement determines the minimum front yard. The minimum front yard for the residential district with the greater front yard requirement must extend at least 150 feet into the TH or TH(A) district. (4) through (7) Reserved. (c) Special exception for carports. (1) The board may grant a special exception to the minimum front yard requirements in this section for a carport for a single family or duplex use when, in the opinion of the board: (A) there is no adequate vehicular access to an area behind the required front building line that would accommodate a parking space; and (B) the carport will not have a detrimental impact on surrounding properties.

Adjacent shared access developments may not be connected or combined to exceed the 36 lot maximum. (2) A shared access development must be restricted by plat to single family use. (3) No building permit may be issued to authorize work in a shared access development until the plat and the shared access area agreement have been recorded in the real property records of the appropriate county, all requirements of the shared access area have been met, and the director has corrected the appropriate zoning map in the offices of the city secretary, the building official, and the department to reflect the restriction to single family use. (4) A shared access development may not be platted as a community unit development (CUD). (d) Shared access area requirements. (1) Design and lighting of the shared access area must be approved by the director. (2) Water and wastewater mains must be installed in accordance with applicable ordinances. (3) Design and location of interior traffic control devices must be approved by the traffic engineer. (4) The fire protection standards in the Dallas Fire Code must be followed. (5) The geometrics of the shared access area must be designed to provide appropriate access for passenger, delivery, emergency, and maintenance vehicles and with a minimum height clearance of 18 feet above the surface of the shared access area. (6) The shared access area must be shown on the plat of the shared access development. (7) The shared access area must front on a public or private street (not an alley), have a minimum width of 20 feet, and have a minimum pavement width of 16 feet. (8) If a guard house is provided, it must be at least 30 feet from the shared access point. (9) If a shared access area entrance is closed at any time, it must be constructed to permit opening of the entrance in emergencies by boltcutters or breakaway panels. (10) A shared access area may serve no more than 18 dwelling units per shared access point. No more than two shared access points may serve a shared access development.

A shared access development must be regulated by a written shared access agreement that: (1) reflects adequate consideration; (2) contains legal descriptions of the individual lots within the shared access development, and of the shared access area; (3) is signed by all owners and lienholders of property in the shared access development and is binding on lienholders by a subordination clause; (4) is approved by the building official; (5) is approved as to form by the city attorney; (6) creates a covenant running with the land (the document may be in any of several forms, including but not limited to, an access easement; a unity agreement; deed restrictions; or homeowners’ association’s covenants, conditions, and restrictions); (7) provides that the owners of property in the shared access development are responsible for lighting, maintenance, and cleaning of the shared access area, and where appropriate, the installation and maintenance of interior traffic control devices; (8) provides necessary easements in the shared access area for the benefit of the individual lots in the shared access development for utilities, storm water drainage, fire protection, lighting, traffic control, government and emergency vehicle access, mail service, meter-reading access, vehicular and pedestrian access, parking, and deliveries; (9) gives the city the right, but not the obligation, to take any action needed to make necessary repairs or improvements within the shared access area, and to place a lien on all lots within the shared access development until the city has received full compensation for that action; (10) provides that the owners of property in the shared access development agree to defend and indemnify the city, and to hold the city harmless from and against all claims or liabilities arising out of or in connection with the shared access development, shared access area, or shared access agreement; (11) provides that it is governed by the laws of the State of Texas; (12) provides that it may only be amended or terminated: (A) with the consent of all the owners and lienholders of property in the shared access development; and (B) after approval as to form by the city attorney, and approval by the director; and (13) provides for the installation, maintenance, and repair of utilities, including electric, water, sewage, and communications located within the shared access area. (f) Code compliance requirements. (1) All code requirements must be met individually by each lot in the shared access development, unless otherwise specified in this subsection. (2) The shared access development is treated as one lot for purposes of compliance with the front, side, and rear yard regulations, applicable landscape regulations, and any prohibition against parking in a front yard. For example, the front yard of the shared access development as a whole determines whether the front yard setback is in compliance with the zoning district regulations, and the individual lots within the shared access development are not individually required to meet front yard setback requirements. (3) Each lot within the shared access development must meet the minimum lot area requirement for the zoning district in which it is located. In multifamily districts, the lot area of individual lots may be up to 20 percent less than the minimum lot area requirement if the average lot area of all lots within the shared access development equals or exceeds the minimum lot area requirement. (4) In all districts other than multifamily districts, the shared access area may not be used to satisfy minimum lot area requirements or determine lot coverage. (5) See Section 51A-10.125(a)(2) for landscape regulations applicable to shared access developments. (g) Guest parking requirements. In addition to any parking spaces required for each dwelling unit, shared access developments must provide 0.25 unassigned spaces available for use by visitors and residents for each dwelling unit. Guest parking spaces must be located where they will not impede access from any other guest parking space or dwelling unit to the shared access point. (Ord. Nos. 24731; 25047; 26333; 28073)

CH, MF-1, MF-1(A), MF-2, and MF-2(A) | 45° (1 to 1 slope) | Terminates at a horizontal distance of 50 feet from the site of origination. (d) Calculation of height restrictions. The horizontal distances used to calculate the height restrictions imposed by the residential proximity slope may be determined by using the lot, block, and right-of-way dimensions as shown on the official plat or zoning maps of the city, or by scale measurement of the distances on such official maps. All dimensions and methodology used in determining the distance measurement are subject to the approval of the building official. (e) Exemption. Certain structures are exempt from the residential proximity slope. See Section 51A-4.408. (Ord. Nos. 19455; 19786; 20308; 21663; 26578)
