Detached Garage Builders in Robbinsdale, MN

Robbinsdale Garage Permit & Zoning Requirements

This page provides a homeowner-friendly summary of key City of Robbinsdale requirements for detached residential garages and accessory buildings. Final rules can vary by zoning, lot width, alley access, and how close the garage is to property lines. Western Construction verifies requirements by address and handles permits as part of a turnkey garage build.

Maximum Garage Size (Based on Lot Width)

Robbinsdale limits detached accessory building size based on the width of the lot and overall accessory building coverage. The maximum size for a single detached accessory building is:

• Lots under 50 ft wide: up to 800 sq ft
• 50–59 ft wide: up to 860 sq ft
• 60–79 ft wide: up to 920 sq ft
• 80–99 ft wide: up to 1,000 sq ft
• 100 ft or wider: up to 1,200 sq ft

Practical note: if there are multiple accessory structures, total accessory building coverage may be capped even if the single-building limit above is higher. We confirm this during address verification.

Garage Height Rules

• Maximum height: 16 feet (measured from grade to midpoint of gable)
• Additional limit: no accessory building may exceed the height of the principal dwelling

Setbacks & Placement

• Front yard: no detached accessory buildings allowed in the front yard
• Rear yard setback: minimum 2 ft (1½ ft may be allowed with a firewall condition)
• Side yard setback: minimum 5 ft
• Alley right-of-way setback: minimum 2 ft
• Garage door/entrance setbacks:
  • Facing a street: minimum 20 ft
  • Facing an alley: minimum 16 ft
• Angled garages: if placed at an angle, increase setback by 2 ft for every 10° of angle

Lot Coverage Limits

• Total accessory buildings: may not exceed 100% of the main floor area of the house
• R-1 and R-2 zones: accessory buildings may not occupy more than 25% of the rear yard
• Attached garages: count toward total accessory building square footage

Fire-Resistance Requirements

• If a detached garage is within 3 ft of a property line, it typically requires a one-hour fire-rated wall on that side.
• If the garage is within 6 ft of a dwelling or addition, additional fire protection may be required.
• Fire-rated assemblies often require 5/8" fire-code gypsum and may restrict wall openings.

Permits, Plans & Inspections

Robbinsdale requires a building permit and plan set. Typical submittals include:

• Survey and scaled site plan showing setbacks and lot lines
• Elevation drawings showing height measurements
• Foundation, framing, and roof details
• Driveway surface type and garage floor elevation

Western Construction prepares plans, submits permits, coordinates inspections, and ensures the garage is built to current Robbinsdale requirements.
