🏗️ Minnesota Garage Building Permit Requirements – Twin Cities Guide

Garage builders and contractors in the Minneapolis–Saint Paul Metro area are required to obtain a building permit before starting any garage construction. Whether you're building a detached or attached garage, Minnesota law mandates that a permit is secured, especially in the Twin Cities and surrounding suburbs.


🧱 Why Permits Are Required for Garage Construction in Minnesota

All garages built in Minnesota must follow the Minnesota Residential Building Code. However, each city interprets and enforces the code slightly differently. That’s why it’s critical to check with your local building department before starting your garage planning process.

For example:

  • Minneapolis garage builders are allowed to build as close as 1 foot from the side lot line.

  • Saint Paul garage builders must maintain at least a 3-foot setback from the side lot line.

  • Alley-facing garages:

    • In Minneapolis: Setbacks range from 6–8 feet, depending on alley width.

    • In Saint Paul: Garages may be placed as close as 2 feet from the alley.

✅ These are just a few reasons why it’s essential to consult your local zoning and permit office before building your garage.


🗂️ Zoning & Garage Permit Application Process

To begin construction on your new garage, you’ll need:

  • Zoning approval

  • A completed garage permit application

  • Two sets of garage construction plans

These plans must clearly show:

  • How your garage will be built (materials, size, structural design)

  • Where it will be located on your property

Once submitted, the local Building Official will review your application. Most permits are approved within one week. The permit fee is typically based on the estimated value of the work.

🔎 Required Inspections for MN Garage Construction

A typical garage construction project in the Twin Cities area involves at least 5 mandatory inspections:

1. Land Survey

Before applying for a permit, hire a licensed land surveyor to stake your lot. This ensures your planned garage will meet setback and zoning requirements.


2. Footing/Slab Inspection

Once the slab is formed with compacted gravel, rebar, and wire mesh in place, the inspector must approve it before concrete is poured.

  • Detached garages typically use a floating slab.

  • Attached garages require frost footings that extend to 42” deep (frost line in Minnesota).


3. Framing Inspection

After the garage is framed and roofed but before siding is installed, the inspector checks:

  • Firewalls and fire-rated eaves

  • Shear walls and structural components


4. Sheathing Inspection

Some cities require an inspection of your sheathing nailing pattern and materials before siding installation. Requirements may vary by location.


5. Electrical Inspections

Two inspections are required:

  • Rough-in inspection (before connecting to the panel)

  • Final inspection (after wiring is complete and power is live)

Your electrician must coordinate both inspections.


✅ Final Building Inspection

Once all prior inspections are passed and features like the garage door and opener are installed, the final inspection ensures everything complies with code.


🔄 Additional Inspections

Local inspectors may require additional inspections depending on your site conditions or to address any code-related questions during construction.


💰 Garage Permit Costs in the Twin Cities

Permit fees vary widely:

  • A simple 2-car detached garage can cost between $200–$800.

  • An attached garage of the same size may cost twice as much.
