Do you need a building permit in Ottawa County, Michigan?
Yes. Ottawa County construction is governed by the Michigan Building Code, with one- and two-family dwelling provisions in the Michigan Residential Code13. Before constructing a building or structure, the owner or the owner's agent must apply in writing to the appropriate enforcing agency; a change in use or occupancy also requires a permit1. Ordinary repairs are the limited exception, but structural work, required-egress changes and work affecting public health or safety are not ordinary repairs1. Michigan's owner-builder licensing exemption applies when a person builds on their own property for their own use and occupancy, but permits, inspections, codes and trade permits still apply8. A new or altered building cannot be used or occupied until the code official issues a Certificate of Occupancy14.
Who issues building permits in Ottawa County, and how do you reach them?
Start with the township or other enforcing agency serving the parcel rather than assuming one county counter handles every building permit2. Port Sheldon Township is one example: its building official reviews plans, issues permits, inspects construction and maintains records for projects in Port Sheldon Township only15. The office is at 16201 Port Sheldon Street, West Olive, MI 49460, and its phone number is 616-399-612115. Separate approvals may still apply: the Port Sheldon office says driveways off public roads need an Ottawa County Road Commission permit, while Ottawa County Environmental Health handles on-site well and septic permits1554. Building-permit fees vary with the enforcing agency; confirm the correct office and current charges before submitting plans.
Does Ottawa County have zoning?
Zoning and land-use rules in Ottawa County are managed by local cities, townships and villages, and their ordinances, codes and procedures vary3. Ottawa County publishes a GIS layer of local zoning districts, but the map does not replace the controlling local ordinance6. In Port Sheldon Township, for example, the zoning administrator enforces that township's ordinance and can be reached through the township office16. Minimum lot size, setbacks, building height, RV use and tiny-home occupancy depend on the parcel's municipality, and no countywide figure was confirmed. As one example, Port Sheldon Township requires at least 20,000 square feet and 100 feet of width for residential lots in its R-1 and Lakeshore Residential districts, and at least 2 acres and 200 feet of width in AG-1171819. Identify the city, township or village and ask its zoning office for the current district rules before relying on the map or a listing description3.
How do septic permits work in Ottawa County?
Ottawa County requires a Health Officer permit before an on-site sewage system is constructed, repaired, enlarged, altered or relocated4. County Environmental Health evaluates the site before issuing the permit, and its vacant-land evaluation can help test feasibility before purchase420. After construction, the applicant or installer must notify the Department before any portion is covered or placed in operation; the Health Officer normally responds to a final-inspection request within two working days, unless another arrangement is made7. The county septic permit requirement has an exception when all sewage is discharged directly into a municipal sewage disposal system, but no countywide rule requiring every parcel to connect to municipal sewer was confirmed21. Building permits and zoning approval do not replace the Health Officer's septic permit4. Only about 1.8% of Ottawa County soils are rated free of severe limitations for a conventional drain field, so do not skip the parcel evaluation10.
Can you live in an RV or tiny home on your land in Ottawa County?
We could not confirm a countywide right to live in an RV or tiny home on private land in Ottawa County; zoning rules and procedures vary by city, township and village3. Michigan guidance treats a tiny house, even one built on wheels, as distinct from a recreational unit and requires applicable local zoning, building, electrical, plumbing and well or septic approvals22. In Port Sheldon Township, permanent dwelling occupancy in a travel trailer or RV is unlawful, and temporary occupancy is unlawful outside a campground approved by the State Department of Health; other townships set their own rules23. Off-grid sanitation is not a workaround: an on-site sewage system needs a county permit, and a privy or outhouse intended to discharge sewage into the ground needs a county construction permit49. Ask the parcel's local zoning administrator about occupancy and placement, and ask county Environmental Health about sanitation before buying for this use320.
Building a home in Ottawa County: the steps, in order
- Identify the parcel's city, township or village, then confirm its zoning district, allowed use, setbacks and building authority36.
- Apply in writing to the appropriate enforcing agency for the building permit before construction1.
- Ask the municipality whether municipal sewer serves the parcel; if on-site disposal is needed, obtain the site evaluation and the Ottawa County Environmental Health septic permit before construction begins214.
- Obtain the county permit for any new or repaired on-site well5.
- If the driveway enters a public road, obtain the separate Ottawa County Road Commission permit identified by the Port Sheldon building office15.
- Have the septic system inspected before it is covered or used, finish required building inspections, and request the Certificate of Occupancy before moving in714.
- If creating a subdivision, take preliminary and final plats through the Ottawa County Plat Board process before state review24.
What to check before you buy land in Ottawa County, Michigan
Start with the county zoning map, then verify allowed use, setbacks and dimensional rules with the parcel's city, township or village because local procedures vary and the map does not replace the ordinance63. Check sewer availability before budgeting for septic, because no countywide requirement to connect to municipal sewer was confirmed and a parcel off sewer needs the county septic permit214. If an on-site system is needed, use the county's vacant-land evaluation before closing: only about 1.8% of Ottawa County soils are rated free of severe limitations for a conventional drain field2010. New and repaired on-site wells require a county permit, and subdivision or site-condominium projects using wells and septic require professional engineered plans and county review525. Confirm legal road access and applicable permit fees before committing; county Environmental Health publishes a fee schedule, but the current amounts were not confirmed26.
Watch-outs
- The Port Sheldon Township offices named in this guide cover Port Sheldon only; confirm the building and zoning authorities for the parcel rather than using those contacts countywide1516.
- A driveway onto a public road needs a separate permit from the Ottawa County Road Commission even where your township issues the building permit; don't assume the township permit covers it15.
- Do not cover or use a new or repaired septic system before county approval; the installer or applicant must request inspection when construction is complete7.
- Michigan's owner-builder exemption concerns builder licensing only; an owner-builder must still follow applicable permit, inspection, code and trade-permit requirements8.

- 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.
