Documents

Required documents

Permit application filed through the Detroit BSEED ePLANS online system at detroitmi.gov/bseed. All new residential permit applications are submitted through ePLANS.
Scaled site plan showing property lines, lot dimensions, existing structures, proposed shed location and footprint, and distances to all property lines — required to confirm compliance with Detroit Zoning Ordinance setbacks and lot coverage limits.
Floor plan and elevations showing shed dimensions, wall heights, roof type, door locations, and intended use.
Foundation details appropriate to the shed size — concrete piers, concrete slab, or treated wood skid system — demonstrating compliance with Michigan Residential Code requirements for the applicable structure type. Permitted sheds must have footings extending below the 42-inch Detroit frost line.
Structural framing details for sheds over 200 sq ft, including wall framing, roof framing, and connection hardware complying with the Michigan Residential Code.

Timeline

Typical timing

Plan review: 10–15 business days for standard residential review
Total cycle: 3–7 weeks from application to final inspection for a permitted shed

Detroit land-use overlay district review or BZA variance proceedings for non-compliant placement add additional time. Utility trade permits are reviewed and inspected on separate tracks. All applications must go through the BSEED ePLANS digital system.

Process

How the permit process works

Apply the ~200 sq ft threshold as the first filter Under the Michigan Residential Code as enforced by Detroit BSEED, accessory structures including sheds at approximately 200 square feet or less in footprint area that comply with zoning setbacks and have no utility connections may not require a building permit. Sheds over 200 sq ft, multi-story structures, and any shed with utility work require a permit. All sheds must still comply with Detroit Zoning Ordinance placement requirements.
Verify zoning placement and check for overlay district conditions Use Detroit's online zoning map at detroitmi.gov to identify the property's residential zoning district and applicable accessory structure setbacks, height limits, and lot coverage maximums under Detroit Zoning Ordinance Chapter 61. Also check for land-use overlay district conditions that may impose additional restrictions. Confirm compliance before ordering a prefab unit or pouring footings.
Plan for Detroit's 42-inch frost line Detroit's frost line depth under the Michigan Residential Code is 42 inches. Permitted sheds must have footings extending at least 42 inches below grade to prevent frost heave. Small prefab sheds on shallow skids may be acceptable for exempt-sized structures. Site-built sheds over 200 sq ft require concrete piers or a full slab. The footing inspection verifies depth before concrete is poured.
Determine utility scope and plan trade permits Decide whether the shed will have electrical wiring, outlets, lighting, plumbing, or mechanical systems. Each utility trade requires a separate Detroit BSEED trade permit and inspection, even when the shed's footprint qualifies for the building-permit exemption. Plan trade permits alongside any main permit application.
Verify Michigan contractor licensing If hiring a contractor, verify they hold a Michigan Residential Builder License or Maintenance and Alteration Contractor License from LARA. The license number must be included in the BSEED ePLANS application. Homeowners may self-permit under the owner-occupant exemption for their own residence. Check license status at michigan.gov/lara.
Submit through BSEED ePLANS For permitted sheds, submit the application through the Detroit BSEED ePLANS system at detroitmi.gov/bseed. Upload the site plan, shed drawings, foundation details, and contractor license and insurance information. All new residential building permits for Detroit must be submitted through ePLANS — paper applications are not accepted.
Pay fees and complete required inspections After plan review approval, pay fees through the ePLANS system or at the BSEED office and post the permit before beginning work. Request inspections through the ePLANS portal or by calling BSEED at (313) 224-2733. Typical shed inspections include a footing inspection (before pour, to verify 42-inch depth), a framing inspection, and a final inspection.

Code basis

What Detroit reviews against

Michigan Residential Code (MRC), based on the International Residential Code (IRC) with Michigan amendments, as enforced by the City of Detroit BSEED under the Michigan Construction Code Act (Act 230 of 1972); Detroit Zoning Ordinance (Chapter 61) for accessory structure setbacks, height limits, and lot coverage.

What can go wrong

Detroit BSEED can issue a stop-work order and require removal or correction of unpermitted shed construction.
A shed placed in a required setback or exceeding lot coverage limits can be ordered relocated or removed at the owner's expense.
After-the-fact permits in Detroit may require exposing foundation and framing elements for inspection, adding significant cost.
Unpermitted electrical or plumbing work creates fire, shock, and water-damage risks that go unverified without BSEED trade inspections.
Detroit land-use overlay district violations may trigger separate enforcement beyond building-code issues.
Civil fines accumulate until violations are resolved; unresolved violations appear in BSEED records and complicate property sales.
Michigan's Seller Disclosure Act (MCL 565.957) requires disclosure of known permit violations in residential real estate transactions, which can affect sale price or require remediation before closing.
Homeowner's insurance may deny claims for damage or injury related to an unpermitted shed, leaving the homeowner fully liable.

FAQ

Common Detroit shed permit questions

Do I need a permit to build a shed in Detroit, MI?

It depends on size and utility connections. Under the Michigan Residential Code as enforced by Detroit BSEED, sheds at approximately 200 square feet or less in footprint that comply with Detroit Zoning Ordinance setbacks and have no utility connections may not require a building permit. Sheds over 200 sq ft and any shed with electrical, plumbing, or mechanical work require a permit. All permit applications must be submitted through the BSEED ePLANS system at detroitmi.gov/bseed.

What is the frost line depth for shed footings in Detroit?

Detroit's frost line depth under the Michigan Residential Code is 42 inches. Permitted shed footings must extend at least 42 inches below finished grade to prevent frost heave — the seasonal ground movement caused by freeze-thaw cycles. The footing inspection verifies depth before concrete is poured. Small prefab sheds on shallow skids may be acceptable for exempt-sized structures, but site-built permitted sheds require deeper footings.

Does Detroit require all shed permits through ePLANS?

Yes. Detroit BSEED requires all residential building permit applications — including shed permits — to be submitted electronically through the BSEED ePLANS system at detroitmi.gov/bseed. Paper applications are not accepted for new residential permits.

What are Detroit's shed setback requirements?

Detroit Zoning Ordinance Chapter 61 governs accessory structure setbacks from property lines in residential zoning districts. Setbacks vary by zoning district. Use Detroit's online zoning map at detroitmi.gov to identify your specific zoning district and look up the applicable rear and side setback requirements before placing or ordering a shed. Also check for any land-use overlay district conditions that may impose additional restrictions.

Does adding electricity to my Detroit shed require a permit?

Yes. Adding wiring, outlets, lighting, or a subpanel to a shed requires a separate Detroit BSEED electrical permit and inspection, even when the shed's footprint qualifies for the building-permit exemption.

How much does a Detroit shed permit cost?

Estimated combined fees (building permit + plan review) for a permitted Detroit shed typically run $150–$470, plus a small Michigan state surcharge. Fees are based on project valuation. Verify current amounts through the BSEED ePLANS portal at detroitmi.gov/bseed.
