Building permits, zoning and land rules in Monroe County, Michigan

#83 of 83 in Michigan

Monroe County, Michigan requires a building permit for new construction, but the county itself doesn't issue it: each city and township is its own enforcing agency, for example the City of Monroe or Raisinville Township1. Zoning works the same way, set township by township and city by city rather than countywide, so what your land can be used for depends on which local unit it sits in2. Septic systems are the rule Monroe County itself runs, through its Environmental Health Division under the county Sanitary Code3. Confirm both building and zoning rules with your specific township, city or village hall before you buy or build.

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

Yes, but Monroe County government does not issue it. Michigan's statewide building code applies everywhere, and permits are required and enforced by whichever local city or township building department covers your parcel, such as the City of Monroe or Raisinville Township1. Michigan's Statewide Jurisdiction List assigns code enforcement to a county enforcing agency only where that list designates county jurisdiction; otherwise the local city, village or township is the enforcing agency, and a written building-permit application has to go to whichever one covers your land9. Construction statewide follows the 2021 Michigan Building Code and Michigan Residential Code, effective April 9, 2025, with Michigan-specific amendments10. Once work is finished, a new or altered building can't legally be used or occupied until the local code official issues a Certificate of Occupancy6. Before you buy, call the township or city hall for your specific parcel to confirm who enforces the code there and what they require.

Who issues building permits in Monroe County?

There is no single Monroe County building department for residential construction; the enforcing agency is whichever city or township your land sits in1. If your parcel is inside the City of Monroe, the City of Monroe Building Division reviews building and site plans, checks zoning compliance, issues the building permit, and inspects the building, plumbing, mechanical and electrical work as the project proceeds11. Reach that office at (734) 384-9186, 120 E. First St., Monroe11. Every other township, city and village in the county runs its own building department the same way; the county's own research names Raisinville Township as another example of a separate enforcing agency1. Start by calling your specific township or city hall, not the county, to find out who to submit your application to.

Does Monroe County have zoning?

Yes, but zoning in Monroe County is set township by township and city by city, not by the county2. Michigan's Zoning Enabling Act lets counties, townships, cities and villages each establish their own zoning districts, but it doesn't define what those districts are; you have to check the ordinance for the specific local unit your parcel is in12. Rezoning a parcel starts with an application at the township hall, goes to the township planning commission for a recommendation after a public hearing, and ends with a final decision from the township board13. That means minimum lot size, setbacks, and whether RVs, tiny homes or manufactured homes are allowed on your land all depend on your specific township or city's zoning ordinance, not on a single countywide rule. The county's Community Planning & Engagement Department can point you toward the right local contact and process, but it doesn't decide zoning questions itself13.

How do septic permits work in Monroe County?

Monroe County's Environmental Health Division enforces the state and local rules for onsite sewage treatment systems4. A new building that will produce sewage must use an onsite sewage disposal system when sanitary sewer is unavailable, and that system must follow the county sanitary code14. Michigan also requires buildings with plumbing fixtures to connect to public sewer where available or use an approved private sewage system15. A homeowner may install the septic system for a habitable building the homeowner intends to occupy, but must first obtain a single-installation license and pass the Health Officer's written examination5. Only 0.3% of Monroe County's soils rate free of severe limits for a conventional drain field, so make the site evaluation an early contingency rather than assuming a standard system will work7. For fees and the site-evaluation process, call the Environmental Health Division at 734-240-790016.

Can you live in an RV or tiny home on your land in Monroe County?

Monroe County's own pages don't give a countywide answer to whether you can live in an RV on your land, because occupancy rules like this are set by each township or city's zoning ordinance rather than by the county2. Ask the planning or zoning office for the specific township or city where your parcel sits before you buy or move a unit in. A permanent tiny home, like any other dwelling, has to meet the same 2021 Michigan Residential Code the local enforcing agency applies to any house, and it can't be occupied until that agency issues a Certificate of Occupancy106. If it also needs its own septic system rather than a sewer connection, that system still goes through the county's Environmental Health Division and its site-evaluation process16. Because both the zoning classification and the building-code path for an RV or tiny home vary by township, get it confirmed in writing from your specific local unit rather than assuming a rule that applied elsewhere in the county applies to your parcel.

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

  1. Identify which township, city or village your parcel is in, since that local unit handles zoning and building permits21.
  2. Ask that local unit's zoning or planning office to confirm the parcel's district and allowed use13.
  3. Ask the Monroe County Road Commission whether the driveway work needs a permit; new, widened, moved, replaced, surfaced or resurfaced driveways are among the activities that may require one17.
  4. If sanitary sewer is unavailable, start the onsite sewage approval with Monroe County Environmental Health144.
  5. Apply to the building department serving the parcel; inside the City of Monroe, that is the City Building Division11.
  6. Build to the applicable Michigan code and complete inspections10.
  7. Request the Certificate of Occupancy after the permitted work is complete and fees are paid; a new or altered building cannot be occupied before the code official issues it6.

What to check before you buy land in Monroe County

Before buying, confirm the parcel's local zoning district and building authority with its township, city or village21. Ask the Monroe County Road Commission about access before relying on an existing entrance or planning a new one, because new, widened, replaced, moved, surfaced and resurfaced driveways may require a permit17. With only 0.3% of Monroe County's soils rating free of severe limits for a conventional septic drain field, obtain the county's site evaluation before treating the parcel as buildable7. Farmland runs about $6,275 an acre, while the typical home value is about $274,1161819. The effective property-tax rate is about 1.2%, and the median annual bill is about $2,4922021. If you plan to divide or plat the land, Michigan's Land Division Act governs subdivision plats and final recordation22.

Watch-outs

  • Monroe County has no single building or zoning department for the whole county; the enforcing agency is whichever township, city or village your parcel is in, so confirm locally rather than assuming a countywide rule12.
  • Only 0.3% of Monroe County's soils rate free of severe limits for a conventional septic drain field, so budget time and money for a site evaluation and possibly an engineered system on most parcels7.
  • The homeowner installation allowance applies to septic work for a habitable building the homeowner will occupy; it requires a single-installation license and a written exam, and it is not a general exemption from building permits5.
  • Driveway work under Monroe County Road Commission jurisdiction may require a permit, including a new, widened, moved, replaced, surfaced or resurfaced entrance17.
