Do you need a building permit in Macomb County, Michigan?

Construction and changes of use or occupancy in Macomb County require a building-permit application to the appropriate enforcing agency; ordinary repairs are exempt except for specified structural, egress, plumbing, electrical, mechanical and safety work¹⁵. Michigan construction codes apply, with one- and two-family dwelling provisions in the Michigan Residential Code¹⁶¹⁷. The current Michigan Building Code is the 2021 code effective April 9, 2025¹⁸. Construction under a Michigan building permit requires periodic inspections¹⁹. Before occupying a new or altered building, request a Certificate of Occupancy after completing the work, finalizing the permits and paying all fees²⁰.

Who issues building permits in Macomb County, and how do you reach them?

Macomb County has no county building program; identify the parcel's city or township and the appropriate enforcing agency before applying². Richmond and Memphis issue their own building permits; septic review in their Macomb County portions remains with the Macomb County Health Department, with state approval where applicable²¹²²²³²⁴⁴. For Macomb Township building permits, call 586-992-0710 or visit 54111 Broughton Road, Macomb, MI 48042²⁵. The township inspects permitted building, plumbing, heating and electrical work²⁶. Macomb Township lets owners pull building permits, recommends that contractors pull them when doing any portion of the work, and says homeowner applications are neither faster nor cheaper²⁷. Michigan's residential-builder licensing exception covers construction on your own property for your own use and occupancy; a building-permit application is still required²⁸.

Does Macomb County have zoning?

Macomb County zoning depends on the city, village or township governing the parcel, including unincorporated land; the county Community Planning Division assists local communities with land-use and zoning functions³. Richmond and Memphis have their own zoning rules; septic review in their Macomb County portions remains with the Macomb County Health Department, with state approval where applicable²⁹³⁰²³²⁴⁴. Macomb Township reviews setbacks, height, parking, lighting and density under its zoning ordinance³¹. Older township provisions specified 1,600 square feet for detached homes in Town Center Neighborhood Edge and 1,200 square feet for single-family principal buildings in Neighborhood General¹²¹³. A Brook Run West variance record identifies an 8,400-square-foot lot minimum for the cited parcel, not a countywide standard³². Confirm current lot and floor-area requirements with Macomb Township Planning & Zoning because the township announced a new ordinance effective September 20, 2026³³³⁴¹².

How do septic permits work in Macomb County?

The Macomb County Health Department handles onsite sewage review countywide, and an acceptable soil evaluation must come before a new-construction septic permit⁴³⁵. Submit the fee, property tax ID, legal description or survey, and a professionally prepared site plan through the Environmental Health portal³⁶³⁵. Online applicants need an Accela Citizen Access account; electronic plans are accepted, but inspections must be scheduled by phone³⁷. A new septic permit costs $489, while a repair permit costs $150³⁸. 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 work¹⁰. Before a sale closes, the owner generally must obtain a septic evaluation, subject to listed exceptions³⁹.

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 occupancy of a single RV or tiny home on an ordinary private parcel in Macomb County; ask the parcel's city, village or township building and zoning offices about the proposed use³. Michigan tiny-house guidance requires applicable local zoning, building, electrical and plumbing approvals, plus health-department approval for wells and septic⁴⁰. Macomb Township's older district-specific floor-area requirements need confirmation against its September 2026 ordinance before planning a small home¹²¹³³³. Macomb County temporary campgrounds may operate for 2 weeks, with a 2-week extension, followed by at least 30 days before another operating period; these campground rules do not establish permission to live in a single RV while building a home⁴¹.

Building a home in Macomb County: the steps, in order

Identify the parcel's city or township, then confirm its zoning ordinance, district and development standards with that jurisdiction's planning office³.
Determine whether municipal water and sewer serve the site; unserved subdivision or condominium projects rely on wells and septic systems⁴².
Complete the soil evaluation, then submit the septic-permit request, fee, property information and professionally prepared site plan through the county portal⁵.
Obtain the required well permit before installing a new or replacement drinking-water well⁴³.
Submit the building-permit application to the appropriate enforcing agency; an owner may apply, but the building-permit requirement remains⁶⁸.
Complete required inspections and obtain a Certificate of Occupancy before using the new or altered building¹⁹²⁰.

What to check before you buy land in Macomb County

Confirm the parcel's city or township first to identify the zoning authority and proper building-permit office⁴⁴⁴⁵. Test the site before relying on a conventional septic field because only about 2.9% of county soils avoid severe limitations for that use¹⁰. A new residential well permit costs $448; required water-sample fees are additional and payable when requesting the final inspection³⁸. For property served by septic or a drinking-water well, ask for the required transfer evaluation before closing³⁹. For subdivisions or condominiums without municipal water or sewage, the Health Department evaluates soils and a test well before engineering-layout review and approval⁴⁶⁴⁷. Land division may add another review track: projects involving county roads require a preliminary plat and later municipal and road-department approvals⁴⁸. A site with any portion in a floodplain must meet local, state and federal construction requirements⁴⁹.

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 limits¹⁴⁵⁰⁵¹.
A septic or drinking-water well serving property for sale generally must be evaluated before closing, subject to the county's listed exemptions⁵².
