Mesquite Parking, Setbacks and Height Rules

Once a lot's district allows the homes you want, the size of the building comes from four rules: the yards, the height limit, the parking, and in Mesquite the wall materials. A setback, or yard, is the open space a building must keep from a property line. This page gives the numbers from the Mesquite Zoning Ordinance for houses, duplexes, townhouses and apartments, the exceptions, and where state law now sets other limits. The Mesquite overview gives the short version.

Yards and Height by District

Sec. 2.302 sets the yards and height for houses and duplexes, and Sec. 2.501 does the same for apartments. All yard figures below are in feet.

Four rules change these yards. First, "Whenever a lot has previously been platted with a greater front building line than required in 2.302," the platted line controls (Sec. 2.301(C)), so read the recorded plat. Second, a key lot is "A corner lot in a single family or duplex subdivision where the rear of the lot abuts or is across an alley from the side lot line" of the next lot; its street side yard "shall be the same depth as the required front yard on the adjoining side street" (Sec. 2.301(D)). Third, when an exterior side yard is fenced with a solid fence at least six feet tall, an accessory building there may use the interior side setback (Sec. 2.601(D)). Fourth, Sec. 2.304(D) lets features reach into yards:

• "Cornices and eaves may project a maximum of thirty (30) inches into any required yard."
• Chimneys, bay windows, balconies, canopies and fire escapes may project three feet into any yard except an interior side yard, if they take no more than one-third of the wall length.
• In an interior side yard, those features may project no more than one-fifth of the required yard width, which is one foot in a 5-foot yard by VanPlex arithmetic.
• A front porch cover up to 8 feet deep, attached to the house and open on the sides, "may encroach into the front setback" (Sec. 2.603(B)).

The residential table sets no lot coverage percentage, so on a house or duplex lot the yards, the height limit and the parking decide how much of the lot a building can take. Accessory buildings are the exception: together they may cover no more than 35 percent of the yard they sit in (Sec. 2.602(A)). Lots that back or side onto an arterial street, a main through road, carry one more rule. Under Sec. 1A.305, the subdivision must build "A long-span precast concrete decorative screening wall, eight (8) feet in height" along the street, or an iron fence with evergreen trees, before permits are issued on the lots next to it. Single-family and duplex lots may face an arterial only if a parallel residential street serves them, or if each lot is at least 100 feet wide with a 50-foot front building line and a circular drive.

How Height Is Measured

Every residential district from AG to D allows 35 feet or 2.5 stories, "whichever is less." The Sec. 6.102 definition measures height as "The vertical distance from average grade to the highest point of a structure," with three exceptions. On mansard or parapet roofs it is measured to the deck line. On hip and gable roofs, "the distance between grade and the mean height level between the eaves and the ridge may be used," meaning the point halfway up the sloped roof. On multifamily buildings it is measured from "the lowest level of fire department vehicle access" to the top plate of the top story.

The code defines a story only by pointing elsewhere: "Story: See definition in building code." Sec. 2.304(E) allows "Spires, domes, cupolas, turrets and similar architectural features" to rise 10 feet above the limit when they cover no more than 10 percent of the building area. Accessory buildings are capped at 15 feet, one story, or the height of the house, whichever is less (Sec. 2.602(B)).

For nonresidential districts, the table in Sec. 3.301 allows 75 feet in O, CV, LC, C and I, 35 feet in GR and SS, and one story in MU. Sec. 3.305 allows taller buildings with larger setbacks: above 75 feet, one more foot of setback from every street for each two feet of height; in MU, up to three stories with two more feet of setback per story above one. Those numbers matter for apartments on commercial land, because SB 840 ties the apartment height limit to the commercial one.

Parking and Garages

Source: Mesquite Zoning Ordinance on municode, Supplement 71, Secs. 2.401 and 2.402, Sec. 2.501(K), Sec. 2.502, Sec. 2.603(N) and Sec. 4.1505.

For houses, Sec. 2.401 puts the two spaces "on the lot behind the front building line," served "by either a double driveway or a single driveway with a flared approach which allows each vehicle to be maneuvered without moving the other." Drives must reach "a paved street or a paved alley" and be "paved with concrete according to the City of Mesquite paving specifications." On AG tracts of two acres or more, an all-weather base strong enough for fire trucks is enough. The Subdivision Ordinance adds that "Access to residential property for required off-street parking shall be from the alley wherever paved alley access is available."

The garage rule depends on the plat date. The enclosed two-car garage applies "for all dwellings on lots in subdivisions for which a final plat was approved on or after October 1, 1984." Lots in older subdivisions need the two spaces but no garage. That same date controls garage conversions: on lots platted before it, the Board of Adjustment may let an owner convert a garage without replacing the spaces (Sec. 2.202(E)).

Carports have their own rules. A rear carport may be up to 528 square feet in the R districts (Sec. 2.603(D)). Front carports, between the house and the street, are "prohibited in all residential zoning districts" except in the pre-approved subdivisions in Table 2.605.01, which include Casa View Heights, Town East Estates, Truman Heights and Whitson Gardens, or by Board of Adjustment special exception. A front carport must attach to the house, cover no more than 400 square feet, reach no more than 20 feet past the building line, and be no wider than 40 percent of the front of the house.

The Masonry Rule and State Law

Sec. 2.303 requires main buildings in AG, R and D to have "at least 90 percent of the total exterior walls, excluding doors and windows, constructed of masonry for all dwellings on lots in subdivisions for which a final plat was approved on or after July 1, 2004." The rest "shall be cementitious fiberboard, natural wood or vinyl siding." For older subdivisions, the codified text says the ratio "shall fall within range" and gives no number. Apartments need 75 percent brick or stone (Sec. 2.501(D)), and townhouses 90 percent, with 100 percent on a street-facing wall (Sec. 2.502).

The City Code also contains Sec. 5-4, which says "The City shall not adopt or enforce any ordinance or other regulation that prohibits or limits, directly or indirectly, the use or installation of a building product or material, approved for use by a national model code published within the last three (3) code cycles." It matches Government Code 3000.002, in force since September 1, 2019. Both list exceptions, among them buildings in historic districts or landmarks designated under the rules each one sets out, and buildings that need a material for windstorm insurance.

So the Mesquite zoning text and the Mesquite building chapter disagree. For an ordinary new house or duplex outside the listed exceptions, the state statute and Sec. 5-4 control over the masonry percentage in Sec. 2.303. A PD ordinance may still carry a masonry stipulation, and deed restrictions may require brick. Ask the Building Official in writing which rule the City will apply to your permit.

Where State Law Sets Other Limits

Two 2025 state laws change these numbers on some Mesquite land. On a small lot of 4,000 square feet or less in a new single-family tract that SB 15 covers, Local Government Code 211.055 bars yards over 15 feet in front, 10 in back and 5 on the side, covered parking, more than one space per home, and any rule requiring fewer than three full stories. The Mesquite rules of 25-foot yards, a two-car garage, two spaces and 2.5 stories cannot be enforced there. The lot size page has the full comparison.

On land zoned for office, commercial, retail or mixed use, SB 840 bars more than one parking space per apartment, a height limit below 45 feet or the commercial height on the site, and a setback stricter than the lesser of the commercial setback or 25 feet. The townhomes, triplexes and apartments page sets those against the Sec. 2.501 rules.

For the building itself, Mesquite adopted the International Residential Code, 2024 Edition, through Sec. 5-552, last amended by Ordinance No. 5249 on May 18, 2026. That code covers houses, duplexes and townhouses. Larger buildings follow the International Building Code, 2024 Edition, under Sec. 5-12. A local amendment in Sec. 5-16 requires sprinklers throughout buildings with a story 35 feet or more above the lowest level that fire trucks can reach.
