How Lansing Handles Accessory Structures: A Practical Guide

Lansing maintains 50 local ordinances across all categories, and 8 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Lansing falls on the strict-to-permissive spectrum compared to other cities.

Carport Rules

Lansing regulates carports as accessory structures under Part 12 Title 6 (Zoning Code) of the Codified Ordinances. Permits are issued by the Department of Economic Development and Planning, with construction subject to the Michigan Residential Code adopted under Part 14 of the Codified Ordinances. Section 406 of the Michigan Building Code sets the open-side and clear-height standards for carports referenced by the local building official.

Key details: Zoning Code: Part 12 Title 6. Building Code: Part 14 (MRC/MBC). MBC Open-Side Rule: Section 406.3. Min Clear Height: 7 feet. Planning Office: 517-483-4085.

Building a carport without a Part 14 building permit, or placing one in a location that does not satisfy the Title 6 zoning district setback and rear-yard coverage standards, is a civil infraction enforceable by the Office of Code Compliance. The city can issue stop-work orders, require removal or after-the-fact permitting, and refer the matter to the 54-A District Court. Historic-district properties altered without Commission approval face a separate violation under Chapter 1224.

ADU Permits

Lansing regulates accessory dwelling units through Chapter 1246 of the Lansing Code of Ordinances (Zoning) administered by the Department of Economic Development and Planning. Under the 2024 ADU pilot program, detached and attached ADUs are permitted in most single-family residential districts (D-1, D-2) subject to size, height, parking, and design standards. All ADU work requires a building permit reviewed under the Michigan Residential Code (adopted via Public Act 230 of 1972, the Construction Code Act).

Key details: Zoning Code: Lansing Code Ch. 1246. ADU Pilot: 2024 expansion to D-1/D-2 zones. Max Size: Lesser of 800 sq ft or 30% of primary footprint. Parking: 1 additional off-street space. State Code Authority: MCL 125.1501 (Construction Code Act).

Construction of an ADU without a building permit is a violation of the Michigan Construction Code Act and Chapter 1246 Zoning. Lansing Building Safety may issue stop-work orders, require after-the-fact permitting at increased fees, and refer continuing violations to the City Attorney. Unpermitted ADUs cannot be registered as rentals under the City's rental certification program and cannot be lawfully leased.

ADU Impact Fees

Lansing does not impose impact fees on accessory dwelling units because Michigan municipalities lack general statutory authority to charge residential development impact fees. The Michigan Supreme Court's 1998 decision in Bolt v. City of Lansing, 459 Mich 152, struck down a Lansing stormwater fee as an unlawful tax, and the controlling rule has prevented Michigan cities from adopting development impact fees ever since. ADU costs in Lansing are limited to building permit fees, plan review fees, and Lansing Board of Water and Light (BWL) service connection charges.

Key details: Impact Fees: None (Bolt v. City of Lansing, 1998). Controlling Case: 459 Mich 152 (1998). Building Permit: Per Lansing fee schedule. Water/Sewer: BWL tap fee only. School Fees: Not authorized.

Building without a permit avoids fees but exposes the property to stop-work orders from the Lansing Building Safety Office, after-the-fact permitting at increased fees, and possible Construction Code Act civil penalties under MCL 125.1521. BWL may disconnect service for unauthorized connections.

The rules around adu impact fees in Lansing lean permissive, but that does not mean anything goes.

ADU Rental Restrictions

Lansing does not currently impose a separate citywide short-term rental licensing scheme on ADUs, but any ADU rented to a non-owner is subject to the Rental Property Certification Program under Public Act 247 of 2014 (MCL 125.526). ADUs let for stays under 30 days are subject to the Michigan 6% Use Tax on accommodations (MCL 205.93a) and the Ingham County Hotel-Motel Tax. Properties adjacent to Michigan State University in the East Lansing border corridor face significant student-rental demand that the certification program is designed to capture.

Key details: Rental Certification: Required (PA 247 of 2014). STR-Specific License: Not currently required. Michigan Use Tax: 6% (MCL 205.93a). Ingham County Hotel Tax: 5% (MCL 141.861). Stays <30 Days: Treated as transient.

Operating an uncertified ADU rental violates Lansing's rental ordinance and exposes the owner to civil infraction citations and possible loss of eviction rights under MCL 125.530. Failure to collect Michigan Use Tax or Ingham County Hotel-Motel Tax on stays under 30 days is enforced by the Michigan Department of Treasury and Ingham County Treasurer respectively. Misrepresenting an STR as a residential dwelling can trigger insurance and zoning enforcement.

ADU Owner Occupancy

Lansing's Chapter 1246 ADU provisions do not impose a blanket owner-occupancy mandate, but any ADU or primary dwelling rented to a non-owner must be registered under the City's rental certification program enabled by Michigan Public Act 247 of 2014 (codified at MCL 125.526). The certification program requires registration, inspection, and a Certificate of Compliance before a unit can be lawfully leased. Properties within historic districts face additional Historic District Commission review independent of occupancy status.

Key details: Zoning Owner-Occupancy: Not required by Ch. 1246. Rental Certification: Required if rented (PA 247 of 2014). State Authority: MCL 125.526. Eviction Tie-In: MCL 125.530 conditions eviction rights. Inspection Cycle: Typically every 2-4 years.

Renting an unregistered ADU is a violation of Lansing's rental certification program and exposes the owner to civil infraction citations, refusal to issue or renew Certificates of Compliance, and possible loss of summary proceedings rights under MCL 125.530 (the Michigan rental statute conditions eviction rights on registration compliance). Historic District Commission violations are separately enforced under MCL 399.205.

ADU Rules

Lansing addresses accessory dwelling units through the zoning code. ADUs may be permitted in certain residential districts subject to size, setback, and parking requirements.

Key details: Permitted: In certain districts. Owner Occupancy: May be required. Permits: Building permits required. Authority: Planning Department.

Unauthorized ADUs face code enforcement and orders to cease residential use.

Shed Rules

Lansing regulates sheds under building and zoning codes. Small sheds under 120 square feet may be exempt from permits but must meet setback requirements.

Key details: Permit Exempt: Under 120 sq ft. Location: Rear or side yard. Height: 15 feet maximum. Setbacks: Must comply with zoning.

Sheds violating setbacks or permits may need to be relocated or removed.

Garage Conversions

Lansing regulates garage conversions through building and zoning codes. Converting a garage requires permits and must maintain minimum parking.

Key details: Permits: Building permits required. Parking: Must maintain minimum requirements. Building Code: Habitable space standards apply. Authority: Building Division.

Unauthorized conversions result in code enforcement and potential orders to restore the garage.

The Bottom Line

Lansing's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lansing is broadly strict or permissive.
