Building Permits in Saint Paul

Saint Paul requires a building permit for most construction, alteration, and repair work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the Saint Paul Department of Safety and Inspections (DSI) — the city's dedicated construction and code enforcement agency, entirely separate from the Planning and Economic Development department that handles zoning.

Saint Paul enforces the Minnesota State Building Code (MSBC) — a mandatory statewide code based on the 2018 International Building Code (IBC) and 2018 International Residential Code (IRC) with Minnesota-specific amendments. The MSBC is adopted and administered at the state level by the Minnesota Department of Labor & Industry (DLI) — Construction Codes & Licensing Division. Every municipality in Minnesota, including Saint Paul, is required to enforce the MSBC; any local amendments must be approved by DLI.

When You Need a Permit

You generally need a Saint Paul building permit for:

• New construction (single-family, duplex, multi-family, commercial, industrial)
• Additions, accessory structures, and Accessory Dwelling Units (ADUs)
• Structural alterations, load-bearing wall removal, and foundation work
• Electrical, plumbing, mechanical (HVAC), and gas line changes
• Reroofing and window or door openings cut into exterior walls
• Swimming pools, decks above a height threshold, and certain retaining walls
• Demolition of any habitable structure
• Change of occupancy or use that affects code compliance

Minor cosmetic work — interior painting, floor coverings, cabinetry without plumbing or electrical changes — is typically exempt. When in doubt, contact DSI before starting work.

Saint Paul DSI — Department of Safety and Inspections

The Department of Safety and Inspections (DSI) is Saint Paul's building authority. DSI is a distinct city department from Planning and Economic Development. Its responsibilities include:

• Issuing building, electrical, plumbing, mechanical, and fire protection permits
• Conducting plan review for compliance with the MSBC and Saint Paul's local code amendments
• Performing all construction phase and final inspections
• Enforcing the Property Maintenance Code for existing structures
• Licensing contractors doing work within Saint Paul

DSI is housed at City Hall and reachable through stpaul.gov/departments/safety-inspections.

Saint Paul Online Permit Portal — Citizen Access

The Saint Paul Online Permit Portal (Citizen Access) at stpaul.gov/dsi is the primary way to apply for building permits. Through the portal you can:

• Create a personal or contractor account
• Submit new permit applications and pay fees online
• Upload construction documents for electronic plan review
• Respond to plan review comments and resubmit corrected documents
• Request and track required inspections
• Download approved permit documents

Walk-in service is available at the DSI office for applicants who prefer in-person assistance or have submittal requirements that cannot be handled online.

Permit Costs

Saint Paul permit fees are set by the City Council and published by DSI. Fees typically include:

• Building permit fee — calculated from project valuation
• Plan review fee — a percentage of the building permit fee
• Inspection fees — included or separately charged depending on permit type
• Minnesota State Surcharge — a state-mandated surcharge on all building permits, collected by DSI and remitted to DLI
• Trade permits — separate permits and fees for electrical, plumbing, and mechanical work (each has its own fee schedule)

Do not rely on third-party fee estimates. Always verify current fees using the DSI fee schedule linked at stpaul.gov/departments/safety-inspections before submitting your application.

Typical Timeline

Second and subsequent correction cycles are typically faster than the initial review if the applicant fully addresses all plan review comments.

The Process

1. Pre-submittal: Confirm zoning district and overlay requirements using the Saint Paul zoning map at the Planning and Economic Development portal; secure any required zoning approvals, variances, or conditional use permits before applying for a building permit
2. Plans: Prepare drawings stamped by a licensed Minnesota architect or engineer where required by the MSBC
3. Submit via Citizen Access: Upload all documents through the Saint Paul Online Permit Portal and pay the applicable fees
4. Plan review: DSI reviews for compliance with the MSBC, Saint Paul's legislative code, and applicable state amendments
5. Corrections: Respond to plan review comments and resubmit through the portal
6. Permit issuance: Pay any remaining fees and receive the approved permit
7. Post permit on site: The approved permit document must be posted visibly at the job site
8. Inspections: Schedule required inspections at each phase of construction through the Citizen Access portal
9. Final: Pass the final inspection and, where applicable, receive a Certificate of Occupancy

Minnesota State Building Code and DLI

Because the MSBC is a mandatory statewide code, Minnesota DLI sets the baseline for all construction in Saint Paul and every other city in the state. DLI's Construction Codes & Licensing Division:

• Adopts and updates the MSBC (Minnesota Rules Chapters 1300–1370)
• Approves any city or county amendments to the code
• Licenses contractors and inspectors statewide, including DSI-certified inspectors
• Hears appeals and issues variances from the MSBC at the state level
• Issues state electrical permits for certain types of electrical work

For state-level code questions, appeals, or contractor licensing, contact the Minnesota Department of Labor & Industry — Construction Codes & Licensing Division at dli.mn.gov.

Inspections

Typical inspection stages for a residential project in Saint Paul include:

• Footing and foundation
• Underground plumbing and electrical
• Framing
• Rough plumbing, electrical, and mechanical
• Insulation and energy compliance
• Drywall
• Final building and trade inspections

Schedule all inspections through the Saint Paul Citizen Access portal. Confirm scheduling lead times with DSI, as availability varies with workload. Work must not be covered before the applicable inspection is completed and approved.

Zoning Approval Before Building Permit

Saint Paul uses a two-step process for projects that require zoning review. The Planning and Economic Development department handles:

• Zoning compliance confirmation (setbacks, height, lot coverage, use)
• Variance and conditional use permit applications (Board of Zoning Appeals)
• Site plan review for larger projects
• Historic preservation review for properties in heritage preservation districts

A building permit application will not be approved by DSI until any required zoning approvals from the Planning department are in place. Applicants should check zoning compliance before investing in construction documents.

Common Reasons for Denial or Corrections

• Plans do not comply with the Minnesota State Building Code or Saint Paul local code amendments
• Missing structural calculations, energy compliance documentation, or licensed-professional stamps
• Zoning conflicts — setbacks, height, lot coverage, or use not permitted in the district — not resolved before DSI submittal
• Incomplete submittal or missing documents in the Citizen Access portal
• Heritage preservation review not completed for properties in a designated preservation district
• Missing or incorrect trade permit applications for electrical, plumbing, or mechanical work
• State surcharge not paid or fee calculation errors
