Building Setbacks & Zoning in Carrollton, TX

Carrollton maintains 136 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Carrollton falls on the strict-to-permissive spectrum compared to other cities.

Lot Coverage Limits

Carrollton's Comprehensive Zoning Ordinance caps impervious coverage at 80% of total lot area in the MF-12, MF-15 and MF-18 Multi-Family Residential Districts. The limit is set in Article 10, Section M's Height and Area Regulations table alongside minimum lot size and density.

Exceeding the 80% impervious coverage cap, or any other zoning ordinance requirement, is a misdemeanor under Article 36, Penalty for Violation, punishable by a fine of up to $2,000, with each day the violation continues counted as a separate offense. Liability extends to property owners, architects, builders, contractors and agents who assisted in the violation, and the ordinance expressly states no culpable mental state is required to prove the offense.

Setback Rules

Carrollton's Comprehensive Zoning Ordinance, updated April 2026, sets side and rear yard minimums by single-family zoning district in Article 7, Section L. In the SF-7/16, SF-7/14 and SF-6.5/12 districts, main structures must clear the rear property line by 20 feet, dropping to 10 feet in SF-5/12, while interior-lot side yards run 6 feet for a one-story house.

Building or maintaining a structure that violates the Article 7 setback table is a misdemeanor under Article 36, Penalty for Violation: a fine of up to $2,000, with each day the encroachment stands charged as a separate offense. The ordinance reaches the property owner and any architect, builder, contractor or agent who assisted, and a culpable mental state is not required for conviction (Ord. No. 1977, 04/19/94).

Structure Height Limits

Carrollton caps single-family homes at 36 feet under Article 7, Section L of the Comprehensive Zoning Ordinance (April 2026 edition), and the limit holds steady across the SF-12/20, SF-10/18, SF-8.4/18 and SF-8.4/16 districts regardless of lot size. Detached accessory buildings are held to 15 feet in every one of those same four zones.

Constructing a home or accessory structure above the district's height cap is a misdemeanor under Article 36, Penalty for Violation, punishable by a fine of up to $2,000 per day the excess height remains uncorrected. The city can cite the property owner along with the architect, builder, contractor or agent who worked on the over-height structure; a culpable mental state is not required for conviction (Ord. No. 1977, 04/19/94).
