Land Use and Zoning Texas 3 Minutes Read · published February 21, 2026 Flag of Texas

Carrollton, Texas requires special controls on construction and development in floodplain and wetland areas to reduce flood risk and comply with federal and state programs. This guide summarizes where restrictions apply, who enforces them, typical permit requirements, and practical steps for homeowners and developers in Carrollton. Refer to the city building permit resources and the municipal code for the controlling text before applying or starting work.[1]

Rules and where they apply

Local restrictions cover mapped FEMA floodplains, regulated wetlands within city limits, and corridors where stormwater management is required. The City regulates new structures, substantial improvements, grading, fill, and certain repairs within these zones. Standards typically address minimum elevation, floodproofing, and limitations on filling or altering wetland hydrology.

  • Permits required for new buildings, additions, and many site changes in regulated zones.
  • Design standards for foundations, utilities, and drainage to reduce flood damage.
  • Documentation such as elevation certificates or engineered drainage plans may be required.
Always check the official map and city permit requirements before work begins.

Specific monetary fines, escalation schedules, and some remedies are set out in the municipal code and administrative rules; where amounts or procedures are not listed on the cited pages below, they are not specified on the cited page and you should consult the controlling ordinance or contact the enforcing office.[2]
