Overview

Zoning amendments supporting a greater variety of 1-6-unit housing types in Saint Paul’s lower density residential districts went into effect on November 26, 2023. These amendments, previously referred to as the 1-4 Unit Housing Study Phase 2, were adopted by City Council on October 18, 2023, in Ordinance 23-43.

This website is intended to share resources and provide information to property owners and prospective developers on zoning requirements, options for adding housing units, development processes, and other applicable regulations.

Zoning and Residential Zoning Districts

Zoning is a method of establishing a land use pattern by regulating the way land is used by property owners in the city. In addition to defining allowable land uses, a zoning ordinance has area standards that regulate the size and location of buildings and structures. Saint Paul’s zoning ordinance is comprised of the Zoning Code and the zoning map that divide the city into various zoning districts and set standards regulating uses in each district.

There are six residential zoning districts: RL large lot residential, H1 residential, H2 residential, RM1 multiple-family residential, RM2 multiple-family residential, RM3 multiple-family residential.

Development Types and Additional Information

The below technical guidance is general to assist project proposers. It is not a substitute for the Zoning Code, Building Code, and other local, State, and federal laws that may also apply to your project. Additionally, a full City staff review does not happen until a full and complete application is submitted/uploaded and fee paid to the City for review.

Development Processes and Approvals

  • Depending on the type, applications for approvals are administered by the Department of Safety and Inspections (DSI) or the Department of Planning and Economic Development (PED) and may require a Board, Commission, and/or City Council approval.
     
  • Consult with PED staff regarding pre-applications or zoning applications for 1-6 unit developments: Reserve a timeslot for a virtual meeting.
     
  • For projects seeking a zoning application for a Conditional Use Permit, Nonconforming Use Applications, Variances, or a rezoning:
  • For projects that have local historic designation:
    • Approval from the Heritage Preservation Commission (HPC) before permit issuance may be required for properties.  Project concepts receive pre-application comments from the HPC at one meeting, followed by a formal design review action (approval or denial) at a future HPC meeting.
    • HPC staff handles these applications: Reserve a timeslot for a virtual meeting.
       
  • Building Plan Review - A general building permit is required to construct, enlarge, alter, repair, move, demolish, or change the occupancy of residences, garages, carports, decks, and similar structures.
