Do you need a building permit in Kent County, Michigan?
Kent County requires a written building-permit application before construction or a change in use or occupancy1. Ordinary repairs are exempt, but structural, egress, plumbing, electrical, mechanical and other health-or-safety work falls outside that exception13. Michigan's adopted building codes apply in Kent County, with residential requirements in the Michigan Residential Code1415. A new or altered building cannot be occupied until the code official issues a Certificate of Occupancy16.
Who issues building permits in Kent County, Michigan?
Kent County has no county building-code program; use Michigan's Statewide Jurisdiction List to identify the parcel's enforcing agency2. Wyoming17, Walker18, Grandville19, East Grand Rapids20, Village of Sparta21, and Tyrone Township22 handle their own building permits. Septic and well permits remain with the Kent County Health Department countywide45. The state online and mail application process applies where Michigan is the enforcing agency; local agencies may use different application methods13. For health applications, call (616) 632-7100; for a driveway entering a county road right-of-way, contact the Road Commission at 616-242-6920 or permits@kentcountyroads.net2324.
Does Kent County have zoning?
Unincorporated Kent County land is subject to township zoning; Kent County has no unified zoning ordinance25. Wyoming26, Walker27, Grandville28, East Grand Rapids29, Village of Sparta30, Sparta Township31, Cedar Springs32, Byron Township33, Tyrone Township34, and Ada Township35 set their own zoning rules. Septic and well permits remain with the Kent County Health Department45. Dwelling size, lot size and setbacks depend on the local ordinance, rather than county zoning standards363738. Accessory dwelling units are allowed under local ordinances, with approval, size and occupancy conditions determined locally39. Ask the parcel's zoning office for the current district standards before siting a home.
How do septic and well permits work in Kent County?
The Kent County Health Department requires a septic permit before installation of an on-site sewage system, and a new-construction application must include a detailed site plan and floorplans4. A county site evaluation determines whether land is suitable for the proposed development and on-site well and septic systems23. Only about 2% of Kent County soils lack severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency10. Mark underground utilities through MISS Dig before the site visit; septic permits, well permits and site evaluations remain valid for 2 years and cannot be transferred40. Work authorized by a county septic permit is subject to final inspection, although the Health Officer may waive it when the completed work can be verified another way41. Evaluations of existing private or commercial well and septic systems are often required before a sale, but the county source does not establish a universal resale-inspection rule42. A separate well permit is required before installing an on-site water-supply well5.
Can you live in an RV or tiny home in Kent County?
We could not confirm a countywide rule authorizing residential RV or tiny-home occupancy on private land in Kent County; ask the parcel's township, city or village zoning office because each jurisdiction has its own ordinance3. For temporary campgrounds and camping events, applications and processing fees go to EGLE at least 14 days before the event, and the separate Kent County Health Department inspection fee must also be paid by that deadline43. Michigan allows qualifying park models on licensed campground campsites, while resort-use tiny houses require local zoning and building approvals and health-department well and septic permits4445. Those campground and resort provisions do not establish permission to live in an RV or tiny home on an ordinary private parcel434445.
Building a home in Kent County: what are the steps?
- Identify the township, city or village containing the parcel and obtain its zoning district rules6.
- Use the statewide jurisdiction list to find the proper building-code agency, then submit its building-permit application and construction documents; Kent County has no county building-code program246.
- Ask the Kent County Health Department for a site evaluation, mark utilities through MISS Dig, and apply for the required septic permit and well permit40475.
- Obtain a Kent County Road Commission driveway permit if the access enters a county road right-of-way24.
- For floodplain construction, filling or grading, file the applicable EGLE permit; specified alterations on watercourses draining at least 2 square miles also require Drain Commission review48.
What should you check before buying land in Kent County?
Make an accepted septic site evaluation a purchase contingency: only about 2% of Kent County soils lack severe limitations for a conventional drain field10. If land will be divided and served by onsite wastewater or individual wells, involve the Kent County Health Department early; health-department review applies to divisions under 1 acre, subdivisions and site condominiums4950. Confirm permitted uses, setbacks and dimensional standards with the township, city or village because Kent County has no unified zoning ordinance9. Check flood maps and proposed grading early because floodplain construction, filling and grading require an EGLE permit, with Drain Commission review for floodway or floodplain-fringe filling or alteration on watercourses draining at least 2 square miles and additional requirements in participating flood-insurance communities48. Drain Commissioner site-development and plat reviews have published procedures and fees, but those are not a countywide building-permit fee schedule5152. Verify whether a driveway enters a county road right-of-way, where a Road Commission driveway permit is required24. The effective property-tax rate is about 1.1%, and the median annual property-tax bill is about $3,0281112.
Watch-outs
- Kent County has no county building-code program and no unified zoning ordinance; identify the parcel's city, village or township before seeking a building permit or zoning approval, while taking septic and well applications to the Kent County Health Department29535.
- A person building a residence on their own property for their own use and occupancy has a conditional builder-licensing exemption, but the building permit and code requirements still apply8115.
- Most local jurisdictions use a 35-foot building-height maximum, but high-density and high-rise zones can differ; confirm the parcel's district before designing54.
- Only about 2% of Kent County soils lack severe limitations for a conventional septic drain field, so secure the county site evaluation before finalizing a build plan1023.

- 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.
