Garage Permits in ME: The Complete Guide

Do I Need A Garage Permit In Auburn, ME?

Yes. In Auburn, most garage projects require a building permit, a zoning permit, or both. While the Maine Uniform Building and Energy Code (MUBEC) exempts structures under 200 sq. ft. from a structural building permit, a Zoning/Placement Permit is required for all permanent structures to ensure compliance with specific city setback requirements.

Key Requirements

• Setbacks: For any garage greater than 120 sq. ft., the side and rear setbacks must be at least 5 ft. (calculated as 50% of the principal building requirement, but never less than 5 ft.).
• Placement: The garage must maintain the full front yard setback required for the primary residence; placement in the front yard is generally prohibited.
• Size Limits: On lots under 2 acres, the maximum first-floor space for a garage is 1,000 sq. ft. There is no maximum size for lots over 2 acres.
• Height: The maximum height for accessory structures in residential zones is typically 20 ft. (structures 120 sq. ft. or less are capped at 10 ft. to qualify for zero-foot setbacks).
• Attachment: Per subsection (d), a deck may attach a principal building to a garage without the garage losing its “accessory” status, provided all other section requirements are met.
