  1. Map for Mobile (Comprehensive Plan)

    Map for Mobile is the City's adopted comprehensive plan, providing the policy direction for future land use, transportation, and community character. It is the foundation document that the Unified Development Code was written to implement.

  2. Unified Development Code (UDC) — Ordinance 64-26(2022)

    On July 12, 2022 the City Council unanimously adopted the new Unified Development Code, replacing land use regulations dating to the 1960s. The UDC is a hybrid that combines form-based and conventional zoning, organized by zoning districts, development standards, and procedures, and is codified as Chapter 64 of the Code of Ordinances.

  3. Downtown Development District (DDD) — Transect Sub-Districts

    Within the UDC, the Downtown Development District (Appendix A) regulates downtown using transect sub-districts including T-6 (high-intensity mixed use), T-5 (medium-intensity mixed use), and T-3 (low-density residential), governed by a regulating plan on the official zoning map.

  4. DDD Amendment Process (2026)(2026)

    On April 16, 2026 the Mobile Planning Commission recommended approval of amendments to the Downtown Development District code (Appendix A of the UDC). The City Council was scheduled to consider the amendments at a public hearing on June 2, 2026 — an example of the city's continuing iteration on the post-2022 UDC.

  5. Flood Resilience — base NFIP standards

    Mobile is a hurricane-prone Gulf Coast city, but as of current published guidance the city does not add a local freeboard above the FEMA Base Flood Elevation; properties in Special Flood Hazard Areas must meet the National Flood Insurance Program minimum. The city's Resilience office publishes flood and elevation requirements.
