Building permits, zoning and septic rules in Saginaw County, Michigan

53Index Score / 100
#70 of 83 in Michigan

Saginaw County, Michigan does not run its own building department: Michigan's Bureau of Construction Codes lists Saginaw County as having no county program, so every city and township in the county enforces the state construction code and issues permits on its own12. The county has no countywide zoning ordinance either; cities and townships zone their own land, so what you can build, and whether you can park an RV or tiny home on it, depends on which municipality your parcel sits in3. Septic is different: the Saginaw County Health Department's Environmental Health Division permits every private well and septic system in the county4.

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

Michigan enforces a statewide construction code, so yes: you need a permit before you build, alter or change the use of most structures anywhere in Saginaw County1. Saginaw County itself is not who issues it. The state's Bureau of Construction Codes lists Saginaw County as running no county code-enforcement program, and its jurisdiction table shows every city and township in the county, from Saginaw Charter Township to Thomas, Tittabawassee and the rest, handling building, electrical, mechanical and plumbing enforcement locally2. Once the work is done, the same local code official has to sign off with a Certificate of Occupancy before a new or altered building can be used6. For a rural buyer this means the building rules for your land depend on which township you're in, not on a countywide code.

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

Start with the clerk's office of the city or township where your parcel sits, since that municipality is the enforcing agency under Michigan's construction code, not Saginaw County2. If you don't know which municipality covers your parcel, or want a starting point, Saginaw County's main line at (989) 790-5200 can route you to the right township or department10. Once you've got the right township, expect the same basic building-permit process every Michigan municipality runs under the state code: submit plans, pay fees set locally, pass inspections during construction, and get your Certificate of Occupancy at the end6. Because permit fees, application forms and inspection schedules are set by each township or city rather than the county, they vary across Saginaw County and you should confirm them directly with your municipality before you budget for the build.

Does Saginaw County have zoning?

Saginaw County has no countywide zoning ordinance of its own; cities and townships adopt and enforce their own zoning under Michigan's township- and municipality-based zoning system3. That means setbacks, minimum lot sizes, accessory-structure rules and whether an RV or tiny home can sit on your land are all decisions made at the township or city level, not by the county3. A parcel just across a township line can carry different rules even though it's in the same county, so confirm the zoning ordinance for the specific township your land is in before you plan a build, not just the county's general reputation. Michigan's own guidance on tiny houses used as resort cabins makes the same point at the state level: even there, local zoning, building, electrical and plumbing approval is still required, and no state rule substitutes for it8.

How do septic permits work in Saginaw County?

Any Saginaw County property that isn't on public water and sewer needs a permit from the Saginaw County Health Department's Environmental Health Division before you build or replace a well or septic system5. If you're buying undeveloped land, you can ask the Health Department for a preliminary soil evaluation before you close, so you know whether the site will support a conventional system and what it will cost5. A permit that's issued is good for two years and spells out minimum construction standards for the system, and Michigan's state guidance confirms local health departments, not a state agency, are the ones who actually permit and inspect onsite systems511. Saginaw County's soils make this worth taking seriously: USDA survey data rates only about 2% of the county's soil as free of severe limits for a conventional drain field, so plan on a site evaluation and be ready for an engineered or alternative system rather than assuming a standard field will work12.

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

There's no countywide answer to this because Saginaw County doesn't zone; the township or city where your land sits does, and RV and tiny-home occupancy rules vary by ordinance3. Michigan's state guidance on tiny houses even at licensed resorts requires local zoning, building, electrical and plumbing approval before occupancy, which tells you a tiny house is treated as a building subject to local rules, not something exempt from them8. Before you buy land expecting to live in an RV or tiny home while you build (or long-term), call the zoning department for that specific township and ask directly whether temporary or permanent RV occupancy is allowed on your parcel's zoning district.

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

  1. Confirm which city or township your parcel is in, since that municipality (not Saginaw County) enforces the building code and zoning that apply to your land23.
  2. Call that township's building and zoning departments to confirm zoning district, setbacks, and whether your planned use (including any RV or tiny home during construction) is allowed3.
  3. If you're not on public water and sewer, contact the Saginaw County Health Department's Environmental Health Division for a soil evaluation and well/septic permit before you finalize house plans5.
  4. If your driveway will connect to a county-maintained road, apply for a right-of-way/driveway permit through the Saginaw County Road Commission's Oxcart Permits system; expect about 10 business days to process a complete application9.
  5. Apply for your building permit with your township or city, and complete the construction, electrical, mechanical and plumbing inspections that municipality requires under the state code13.
  6. Request your Certificate of Occupancy from the same local code official once all permitted work is finaled and fees are paid6.

What to check before you buy land in Saginaw County

Confirm the zoning district and permitted uses with the specific township or city, since Saginaw County itself sets none of this3. Ask the Health Department's Environmental Health Division for a preliminary soil evaluation on any parcel without public sewer; with only about 2% of the county's soil rated free of severe limits for a conventional drain field, many sites need an engineered system, which costs more and takes longer to permit512. Check driveway access with the Saginaw County Road Commission if the frontage is a county road: a residential driveway must run at least 18 feet wide, and no closer than 50 feet to an intersecting road's right-of-way in most cases, so an oddly shaped lot can complicate access9. Saginaw County is mostly flat, glacial lake-plain land, with essentially all of it at 15% slope or less, which keeps grading costs low but doesn't change the drainage and septic-siting questions above14. Finally, budget for property tax: the county's effective rate runs about 1.6% of value, with a typical bill near $2,190 a year1516.

Watch-outs

  • Saginaw County itself issues no building permits and has no county building or zoning department; every request routes to the city or township where the land sits, and contact details for that specific municipality are not in this guide's verified offices2.
  • Owner-builder exemption status for Saginaw County is unconfirmed on official sources; ask your township building department directly before assuming you can act as your own contractor7.
