Do you need a building permit in Macomb County, Michigan?
Yes. Construction of a building or structure in Macomb County requires a written permit application to the appropriate enforcing agency, as does a change in use or occupancy; ordinary repairs generally do not require a permit, subject to the listed safety-related exceptions1. The Michigan Building Code governs buildings statewide, while one- and two-family homes fall under the Michigan Residential Code11. Macomb Township illustrates the local process: its Building Department inspects permitted building, plumbing, heating and electrical work12. Because the enforcing office depends on the parcel's jurisdiction, identify the city or township before applying2.
Who issues building permits in Macomb County, and how do you reach them?
Macomb County does not operate a single building department for every parcel; the applicable city or township is the first place to identify the enforcing agency2. For a parcel in Macomb Township, contact the Macomb Township Building/Code Enforcement Department at 54111 Broughton Road, Macomb, MI 48042 or 586-992-071013. Michigan permits an owner, the owner's builder, architect, engineer or agent to submit the written building-permit application8. Macomb Township specifically lets a property owner pull a permit, but recommends that a contractor pull it when a contractor performs any part of the work; a homeowner permit is neither faster nor cheaper14.
Does Macomb County have zoning?
Zoning in Macomb County is administered at the city or township level, so a parcel's municipality controls the usable district rules3. In Macomb Township, Planning & Zoning confirms the appropriate zoning category and reviews development for setbacks, height limitations, parking, lighting and density1567. Macomb Township's current ordinance took effect September 20, 202615. We could not confirm countywide numeric rules for minimum dwelling size, minimum lot size or lot coverage; ask the planning office serving the parcel. The same local check is necessary for agricultural uses because we could not confirm a countywide agricultural exemption.
How do septic permits work in Macomb County?
The Macomb County Health Department evaluates proposed building sites, conducts soil evaluations, issues septic permits and inspects onsite systems4. A new septic permit costs $489 in 2026, while a soil evaluation costs $243 and engineered septic plan review costs $71016. Apply through the Environmental Health online portal after registering for an account; electronic plans are accepted, but inspections must be scheduled by calling 586-469-523617. Only about 2.9% of Macomb County soils avoid severe limits for a conventional drain field, so complete the soil evaluation before assuming a standard system will work5. Buildings with plumbing must use public sewer where available or an approved private sewage system18.
Can you live in an RV or tiny home on your land in Macomb County?
We could not confirm a countywide rule allowing long-term RV living, temporary camping or tiny-home occupancy in Macomb County. The parcel's city or township administers zoning, so ask its planning office whether the proposed dwelling and occupancy are allowed in that zoning district3. Michigan guidance does not treat a tiny house as a recreational unit merely because it is built on wheels, and tiny houses covered by that guidance still need applicable local zoning, building, electrical and plumbing approvals plus health-department approval for wells and septic19. Do not assume wheels avoid construction or land-use review.
Building a home in Macomb County: the steps, in order
- Identify the parcel's city or township, then confirm its zoning district and development standards with that local planning office3.
- Determine whether municipal water and sewer serve the site; unserved subdivision or condominium projects rely on wells and septic systems reviewed by the Macomb County Health Department20.
- Apply online for county septic and well approvals, and call the health department to schedule inspections17.
- Submit the written building-permit application to the appropriate enforcing agency; an owner may apply, but the permit requirement remains8.
- Complete required inspections; in Macomb Township, owner-built work may not be covered or put into operation before the Building Inspector approves it9.
- Obtain the required Certificate of Occupancy before using a new or altered building21.
What to check before you buy land in Macomb County
Confirm the parcel's city or township first because that jurisdiction controls zoning and identifies the proper building-permit office23. Test the site before relying on a conventional septic field because only about 2.9% of county soils avoid severe limitations for that use5. A new residential well requires a permit or notice through the local health department before drilling, and Macomb County's 2026 fee is $448, excluding required water-sample fees1016. If the land is part of a proposed subdivision involving roads under county jurisdiction, the county road department requires a tentative preliminary plat before land plans and preliminary designs begin22. We could not confirm a general countywide driveway-permit rule or the operative floodplain-development requirements, so ask the road agency and local building office before closing.
Watch-outs
- Macomb Township's owner-builder terms are not a countywide shortcut: the owner must live in or be about to occupy the single-family dwelling, and work must remain open until inspected and approved9.
- Macomb Township's zoning ordinance took effect September 20, 2026, so use the current ordinance when checking its zoning category, setbacks and height limits1567.
- Macomb County Environmental Health accepts septic and well applications online, but inspection scheduling is by phone rather than through the portal17.
