Zoning, building permits and septic in Troy Township, Athens County, Ohio

Athens County, Ohio has no adopted county zoning, and no Troy Township zoning ordinance or building department could be confirmed1. Whether a home in Troy Township needs a building permit depends on whether a certified residential building department has jurisdiction there2.

Does Troy Township, Ohio have zoning?

Athens County has no adopted zoning regulations, so the county does not zone land in Troy Township1. The county does run subdivision and floodplain regulations9.

We could not confirm whether the Troy Township trustees have adopted a township zoning resolution, or any rules on RVs, tiny homes, minimum home size, lot size or setbacks. Do not assume the answer is "none": ask the Troy Township trustees or fiscal officer before you buy. Because Athens County has no zoning of its own, a township resolution, if one exists, would be the only zoning that applies.

Do you need a building permit in Troy Township?

Ohio's residential code says that when no certified municipal, township or county building department has jurisdiction, the owner is not required to submit construction documents, request inspections or obtain a certificate of occupancy10. Athens County states it has no building codes except for floodplain requirements11.

We could not confirm which certified department, if any, covers Troy Township. Confirm that with the Athens County Regional Planner9 before you assume no building permit is needed. Even without one, floodplain, subdivision, septic and well rules still apply12.

How do septic permits work in Troy Township?

Septic permits for land in Troy Township come from the Athens City-County Health Department313. A new or replacement home sewage system needs a soil and site evaluation, a design, a permit application and a fee, and only a registered installer may install it5.

Soil matters here: only 3% of soils in Athens County rate "not limited" for a conventional drain field, so expect a site evaluation and possibly an engineered system14. Wells also need a permit from the board of health before drilling8.

Floodplain, land splits and driveways in Troy Township

Any development in a floodplain needs a permit, including houses, manufactured homes, accessory buildings, filling and grading4. The county's residential floodplain permit fee is $7515.

Splitting a parcel needs a permit from the County Planner's office6; a subdivision includes any division that leaves a parcel under five acres16. A driveway onto a county road needs a culvert permit from the Athens County Engineer717. We could not confirm the rule for township roads, so ask the trustees.

Can you live in an RV or tiny home in Troy Township?

Athens County, which has no zoning, does not restrict RV occupancy through county zoning in unincorporated areas18. That is a county answer only. We could not confirm any Troy Township rule on long-term RVs, camping, tiny homes or manufactured homes, so ask the township trustees first.

Whatever the zoning answer, a sewage system or hookup and a well still need approval from the health department5. A tiny home built as a permanent house falls under the same building-permit question as any other home.

Building a home in Troy Township: the steps, in order

  1. Ask the Troy Township trustees whether the township has zoning, and the County Planner whether a certified building department covers the parcel9.
  2. Check whether the parcel lies in a floodplain; if so, apply for the county floodplain permit4.
  3. If you are splitting land, get subdivision approval first6.
  4. Apply to the Athens City-County Health Department for the septic and well permits13.
  5. Get a driveway culvert permit if you will use a county road17.

What stays with Athens County, and what to check before you buy

Septic, wells, floodplain, subdivision and county-road driveways all stay with Athens County and its health district, not the township319. The county page is at Athens County.

Athens County's effective property tax rate is 1.2%20, and its median property tax bill is $2094 a year21. Farmland sells for about $4123 an acre22. If the land is farm use, a county or township zoning inspector can issue a certificate declaring a building agricultural, which exempts it from state building approval23.

Watch-outs

  • We could not confirm a Troy Township zoning resolution or building department; ask the township trustees and the Athens County Regional Planner before you buy9.
  • A new septic system or well needs a board of health permit before work starts58.
  • A floodplain permit applies even where no building permit does4.
