Do you need a building permit in Warner Township, MI?

Warner Township construction requires a written building-permit application to the appropriate enforcing agency before work starts, and changing a building’s use or occupancy also requires a building permit.1 Ordinary repairs are exempt, but structural changes, changes to required exits, and utility or electrical work affecting safety are outside that exemption.1 Michigan’s residential-builder licensing exemption can apply when you build for your own use and occupancy on your own property; the exemption does not remove building-permit, inspection or code requirements.7 Ask the building official to classify your proposed work before relying on the ordinary-repair exemption.1

Who handles building permits and inspections in Warner Township?

Antrim County Construction Code is the building-office contact for Warner Township’s county-administered residential inspections.2 The department retains building, plumbing, electrical and mechanical permits, and its website links building requirements, fee schedules and code-compliance checklists.8 Contact the department at 231-533-8373 or [email protected] to discuss the application and which trade permits your project needs.8 Michigan’s application guidance calls for identifying the appropriate enforcing agency; construction documents are generally required, although the building official may waive them when the application description establishes code compliance.9 For land outside the township, consult the Antrim County guide.8

Does Warner Township have zoning, and can you live in an RV or tiny home?

We could not confirm Warner Township’s zoning ordinance, zoning districts, setbacks or minimum lot size; ask Warner Township Clerk for a written answer tied to the parcel and proposed use.5 We also could not confirm whether Warner Township allows private-land RV living, camping while building, tiny-home occupancy, manufactured homes or accessory dwellings; raise each intended use with the clerk before committing to land.5 A tiny home proposed as a building still faces Michigan’s construction-code and building-permit requirements, and a new or altered building cannot be occupied before the code official issues a certificate of occupancy.10111

How do septic and well permits work in Warner Township?

The Health Department of Northwest Michigan administers onsite sewage rules throughout Antrim County, including Warner Township.3 A septic system needs a construction permit and final approval, including when a system is repaired, altered or extended.6 HDNW evaluates the site before issuing a septic permit; do not install the system before that permit is issued.12 The 2026 application lists $378 for a new or replacement residential septic permit and $287 for a residential well permit.13 Residential wells also require a site evaluation before permitting and a final review after installation.4 Antrim County’s soil figures rate only 8% of soils “not limited” for conventional drain fields; that countywide figure supports arranging a parcel evaluation, rather than assuming septic is impossible.14

What are the steps to building a home in Warner Township?

Start with the proposed use and site layout, then work through the separate township, health and building questions.5129

  1. Ask Warner Township Clerk to confirm the parcel’s land-use rules and any proposed temporary accommodation.5
  2. Arrange HDNW’s septic and residential-well site evaluations and submit the applicable applications with the correct fee.12415
  3. Confirm the building enforcing agency and submit the building application and required construction documents before construction.91
  4. Request construction inspections as work progresses, then obtain the certificate of occupancy before using a new or altered building.211

What should you check before buying land in Warner Township?

For Warner Township land near a river, stream or drain, ask about EGLE floodplain review before selecting a house site: new residential construction is prohibited in the regulated floodway, and non-floodway construction has additional conditions.16 A driveway accessing a Michigan state trunkline highway requires an MDOT driveway permit in addition to the local building permit; ask the road authority about access before designing the driveway.17 We could not confirm Warner Township’s public-water or sewer connection requirements or alternative off-grid sanitation options; discuss the intended water and waste systems with HDNW before relying on them.43

Watch-outs

  • Building approval does not authorize immediate move-in: a new or altered Warner Township building needs a certificate of occupancy before use.11
  • Keep inspections moving during Warner Township construction; the county handout says building permits can become invalid when work is suspended or abandoned, or required inspections are not requested and conducted.2
  • We could not confirm Warner Township RV occupancy or setback rules; request parcel-specific clarification from the township clerk.5
