Barndominium Builders in Washtenaw County, Michigan
Outside Ann Arbor and Ypsilanti, Washtenaw County turns quickly into farmland, woodlots and small lakes, and that township ground is where most barndominiums in this part of Michigan get built. The catch is that no single office covers it all. Your township sets the zoning; the building permit may come from the township itself, from a joint construction authority shared by neighbouring communities, or from the county's building office, which serves only a handful of townships; and septic and well approval runs through the county health department. Knowing which combination applies to a parcel before you buy saves weeks later. We build turnkey barndominiums and supply barndominium kits for owners who want to erect the shell themselves, and a pole barn home is a natural fit on open acreage with room for a shop. We also handle site preparation, from the driveway and pad to erosion control, and the permitting paperwork with each office. If you are weighing a lot inside Ann Arbor, see the Ann Arbor page instead. Otherwise, tell us the township and parcel through the survey and we will map out who approves what.

Permits, Zoning and Septic in Washtenaw County
Four offices usually decide whether a barndominium can go on a given parcel. Here is who they are in Washtenaw County, taken from the office or document that publishes each rule. Rules change, so check them again against your parcel before anything is drawn.
Your township, city or village building department; Washtenaw County Building Inspection in the units it serves
Washtenaw County Building Inspection enforces the construction code in only seven places: Augusta, Lodi, Saline, Scio, Sharon and Webster townships and the City of Dexter. The county lists every other township, city and village as outside its jurisdiction, so their residents apply to their own local building department or authority. The county does not permit every parcel; check the BCC Statewide Jurisdiction List for your township.

Your township (Lodi Township shown as a representative example)
Zoning is set township by township, and cities and villages zone separately. In Lodi Township, a rural township southwest of Ann Arbor, township zoning compliance is required before the county building department will issue a permit; the township first asks for a road commission driveway permit, a soil erosion permit or waiver, scaled plans, and a site plan showing setbacks, septic and well.

Washtenaw County Health Department, Environmental Health Division
Before building a home without municipal or central sewer, a county sanitarian performs a soil evaluation, and it must be approved before you can apply for the sewage permit. Your township office can say whether sewer reaches the parcel. Wells are drilled by state-registered well contractors, normally at least 50 feet from the septic tank and drain field.

Washtenaw County Water Resources Commissioner (in its jurisdictions)
The Commissioner's office runs the soil erosion program in fourteen jurisdictions, among them Augusta, Lodi, Northfield, Salem, Saline, Scio, Sharon, Webster and York townships. For a home it requires a permit when earth changes within 500 feet of surface water disturb more than 225 square feet; farther away, work under one acre may qualify for a waiver.

- Other soil erosion agencies
- Outside the Commissioner's own jurisdictions, the county names six other local soil erosion agencies: the City of Ann Arbor Building Division, Ann Arbor Township, Pittsfield Township, Ypsilanti Township, the Chelsea Area Construction Authority and the Western Washtenaw Construction Authority (Washtenaw County Water Resources Commissioner, read 27 September 2026).
- Zoning compliance comes before the permit
- Lodi Township explains that its zoning compliance permit tells the county building department the location and use of the project have been approved by the township, and that it is not a permit to build or an approval of the plans, which the building department reviews separately (Lodi Township, read 27 September 2026).

Building on land near Washtenaw County
Rural Washtenaw parcels range from open cropland to wooded, rolling ground dotted with lakes, ponds and wetlands. Near any of those, soil erosion rules tighten sharply, and EGLE regulates many wetlands and floodplains, so have a parcel checked before you buy. Most township land relies on a private well and a septic field, and the soil evaluation decides where the drain field can go, which in turn shapes where the house and shop sit. Most of Washtenaw County carries a 25 psf ground snow load in the state table, dropping to 20 psf in Ann Arbor and a listed group of other cities and townships.
