Summary
Carrollton's Comprehensive Zoning Ordinance caps new single-family homes in the SF-12/20, SF-10/18, SF-8.4/18 and SF-8.4/16 districts at 36 feet in height and 45 percent lot coverage, with accessory buildings held to 15 feet. The same Article 7 table also sets minimum dwelling floor areas of 1,600 to 2,000 square feet and requires 70 percent brick or stone on the main dwelling's exterior before a building permit issues.

Full Breakdown
4/16. 4/16 (Ord. No. 3421, 01/11/11 cross-references accessory-building rules in Section K(3)(h)). Regardless of which district a lot sits in, the maximum height of the dwelling unit is fixed at 36 feet and accessory buildings at 15 feet, and building coverage cannot exceed 45 percent of total lot area (Ord. No. 1844, 11/03/92), so a house cannot be scaled up to swallow the whole lot even where floor-area minimums are low. Section L also requires that main dwelling exteriors carry at least 70 percent brick or stone below the top plate line, excluding doors, garage doors and windows, unless the Planning & Zoning Commission approves an alternate material (Ord.
No. 1997, 06/21/94). These figures are checked by the city's plan review staff against the submitted building plans before a permit for new construction, an addition, or a substantial remodel is issued, which is the point at which an oversized or out-of-scale ('mansionized') design gets caught in Carrollton's SF districts.
Violations & Fines
Article 36, Penalty for Violation, makes it a misdemeanor to build or alter any building in violation of the zoning ordinance's detailed statements or approved plans, including the Article 7 height, coverage and floor-area standards. Violators face a fine of not more than $2,000, and each day the violation continues is a separate offense. Owners, architects, builders, contractors and agents who assist in the violation are each guilty of a separate offense and can each be fined; no culpable mental state need be proven.
