Saginaw County, Michigan requires a building permit before construction or a change in use or occupancy, but the appropriate state or local enforcing agency—not a county building department—issues it12. Saginaw County does not administer countywide zoning; each township, city or village controls local land use34. The Saginaw County Health Department handles private well and septic permits5.

Do you need a building permit in Saginaw County, Michigan?
Yes. Before constructing a building or structure in Saginaw County, the owner or agent must submit a written permit application to the appropriate enforcing agency; a change in use or occupancy also requires a permit12. Ordinary repairs are exempt only when they do not involve the listed structural, egress, trade-system, public-health or safety work12. Michigan construction codes govern buildings statewide, with one- and two-family dwelling provisions in the Michigan Residential Code13. Permitted construction is subject to periodic inspections by the enforcing agency14. A new or altered building cannot be occupied until the code official issues a certificate of occupancy after work is completed, permits are finalized and fees are paid11.
Who issues building permits in Saginaw County, and how do you reach them?
Saginaw County does not operate a county building-code program; the state jurisdiction list identifies local enforcement for municipalities such as Saginaw Township2. For unincorporated Saginaw County land, start with the township containing the parcel to identify the building-code enforcing agency15. Reese, a village mainly in Tuscola County that reaches into Saginaw County, handles its own building permits16. Septic and private-well regulation stays with the Saginaw County Health Department throughout Saginaw County, including incorporated areas5. If you need help finding the local office, call the county main line at (989) 790-520017. Building-permit applications require construction documents unless the building official waives them because the description establishes code compliance; state applications can be submitted online or by mail18. Ask the enforcing agency for building-permit fees and inspection scheduling before ordering work.
Does Saginaw County have zoning?
Saginaw County does not conduct planning or zoning at the county level; townships, cities and villages handle those functions3. For unincorporated Saginaw County land, ask the township zoning office for the parcel's district and permitted uses4. Reese, a village mainly in Tuscola County that reaches into Saginaw County, administers its own zoning inside village limits19. The Saginaw County Health Department retains septic and private-well authority for Saginaw County addresses inside villages as well as townships5. No county zoning ordinance supplies minimum dwelling size, lot size, setbacks, lot coverage or building height for unincorporated Saginaw County, but local and state standards may still apply2021222324. Obtain the local ordinance before relying on acreage or a nearby property's use.
How do septic and well permits work in Saginaw County?
The Saginaw County Health Department regulates onsite wastewater systems and private wells under the county Environmental Health Code5. Property without public water and sewage service needs a wastewater permit before a septic system is built or replaced, and the county issues it only when site conditions are acceptable6. A complete health application includes the registered deed, fees and notice that soil borings are complete; processing depends on the soil, water table, drainage and other environmental findings25. The residential septic permit is $570, while a residential Type III well permit is $26526. A new or replacement private well also requires a county permit; the well application needs a site plan and fee727. The county inspects a completed septic system before it is covered28. Only about 1.8% of county soils are rated without severe limits for a conventional drain field, so request a site evaluation before buying29.
Can you live in an RV or tiny home on land in Saginaw County?
Saginaw County sets no county zoning restriction on RV or tiny-home occupancy; the township, city or village administers applicable local land-use restrictions910. That does not establish permission to live in an RV or tiny home on a particular parcel910. Ask the local zoning office whether the district allows the proposed dwelling, long-term RV living or temporary occupancy during construction4. A tiny house proposed for occupancy still needs applicable local zoning, building, electrical and plumbing permits and final approvals30. Off-grid living does not avoid sanitation rules: a habitable property must connect to available public sewer, subject to the stated alternative-system exception, or obtain approval for onsite wastewater disposal3132.
Building a home in Saginaw County: the steps, in order
- Identify the township, city or village and obtain its zoning district and dimensional standards, because Saginaw County does not administer countywide zoning3.
- Confirm the building-code enforcing agency and submit the building-permit application and required construction documents to that agency151218.
- If public sewer is unavailable, submit the deed, fees and completed-soil-boring notice needed for county health review; obtain a county well permit if a new or replacement private well is planned257.
- If the site lies wholly or partly in a regulated floodplain or wetland, secure the required state approval before the county health permit33.
- Complete required building inspections and the septic inspection before covering the system1428.
- Request the certificate of occupancy after permitted work is complete and permits and fees are final11.
What should you check before buying land in Saginaw County?
Confirm the parcel's municipality, zoning district, permitted use, setbacks and minimum dwelling or lot standards with the local zoning office; Saginaw County itself supplies none of those zoning dimensions4202122. For land without public sewer, request a preliminary soil evaluation from the Health Department before closing34. A parcel in a regulated floodplain or wetland needs state approval before the county will issue its health permit35. Confirm whether the road is county-maintained or a state trunkline: work in county right-of-way requires a Road Commission permit, while a state-highway driveway requires an MDOT permit3637. Finally, verify whether public sewer is available because connection may be mandatory31.
Watch-outs
- Do not interpret the absence of countywide zoning as unrestricted land: township, city and village ordinances can control use and dimensions34.
- The residential-builder licensing exception applies when a person builds for personal use and occupancy on that person's own property; Saginaw County building permits are still required8.
- Installing a septic system or well without a permit can trigger double the normal county fee26.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
