University City Zoning Overview

University City is an inner-ring suburb of approximately 34,800 residents in St. Louis County, Missouri. Known for its walkable neighborhoods, diverse housing stock, and the iconic Delmar Loop commercial district, University City regulates land use and development through its zoning ordinance, codified in the University City Municipal Code. The code divides the city into seven primary zoning districts -- four residential (R-1A, R-1B, R-2, R-3), two commercial (C-1, C-2), and one industrial (M-1) -- each with specific standards for lot size, setbacks, height, and permitted uses.

Residential Zoning Districts

University City's residential districts range from low-density single-family zones to multi-family areas. The R-1A and R-1B districts are exclusively single-family, while R-2 permits two-family dwellings (duplexes) and R-3 allows multi-family housing including apartments.

District Type Min Lot Size Front Setback Side Setback Rear Setback Max Height
R-1A Single-Family 7,500 sq ft 30 ft 5 ft 30 ft 35 ft
R-1B Single-Family 5,000 sq ft 25 ft 4 ft 25 ft 35 ft
R-2 Two-Family 5,000 sq ft 25 ft 4 ft 25 ft 35 ft
R-3 Multi-Family Varies 25 ft 10 ft 25 ft 45 ft

The R-1B district covers many of University City's established neighborhoods with their characteristic early 20th-century homes on compact lots. The R-3 district, which allows buildings up to 45 feet, accommodates the higher-density residential areas near commercial corridors.

Commercial and Industrial Districts

The C-1 (Commercial) and C-2 (General Commercial) districts serve the city's retail and business needs, including the well-known Delmar Loop area. The M-1 (Industrial) district accommodates manufacturing and warehousing uses. Dimensional standards for these districts vary; consult the municipal code for specific requirements.

ADUs (Accessory Dwelling Units)

University City does not currently have a specific ordinance authorizing ADUs (Accessory Dwelling Units). Missouri has no statewide ADU mandate, so local jurisdictions set their own rules. While accessory structures like detached garages and sheds are permitted under general zoning provisions, constructing a separate dwelling unit within an accessory building is not expressly allowed. Property owners interested in adding a secondary dwelling should contact Community Development at (314) 505-8500 for guidance.

Development Process

Development in University City generally requires obtaining the appropriate permits from the Community Development department. The process typically involves:

  1. Zoning Verification -- Confirm that your proposed use is permitted in the applicable zoning district by reviewing the municipal code or contacting Community Development
  2. Site Plan Review -- For commercial and multi-family projects, submit a site plan for review by the Planning Commission
  3. Building Permit -- Apply for a building permit with construction documents that comply with the 2018 IBC/IRC as locally adopted
  4. Inspections -- Schedule required inspections during construction
  5. Certificate of Occupancy -- Obtain final approval before occupying the structure

For projects that do not conform to existing zoning, property owners may need to seek a variance or rezoning through the Board of Adjustment or Planning Commission.

Key Considerations

Before starting any development project in University City, property owners should:

  • Verify the zoning classification of their property through St. Louis County GIS or by contacting the city
  • Review setback, height, and lot coverage requirements for their specific zoning district
  • Check for any overlay districts or special regulations that may apply
  • Determine if the property is in a flood zone using FEMA's Flood Map Service Center
  • Confirm whether HOA covenants or deed restrictions apply to the property
  • Contact Community Development at (314) 505-8500 for pre-application guidance
