#32 of 88 in Ohio

Unincorporated Trumbull County, Ohio requires a building permit for most construction, additions and repairs, issued by the Trumbull County Building Inspection Department12. The county itself has no zoning: zoning is set and enforced township by township, and only four of Trumbull County's townships (Brookfield, Mecca, Mesopotamia and Vernon) have none at all34. Septic permits go through the Trumbull County Health Department, and the county's building department wants that squared away before it issues a permit56. Local soils are a real constraint, too: none of Trumbull County's soils rate free of severe limits for a conventional drain field in the USDA soil survey7.

Do you need a building permit in Trumbull County, Ohio?

Yes. Trumbull County requires a permit before you build a new home, add a patio, deck, chimney, garage or pole barn, put in a swimming pool, add ventilation or HVAC, wire electrical, or put up a storage shed over 200 square feet11. The same requirement covers re-roofing, siding, porch work, foundation repairs and any demolition, since a demolition permit keeps the county's tax rolls current11. Ohio's residential building code applies uniformly wherever a certified building department, like Trumbull County's, enforces it12. The county adds a 1% state assessment plus a $10 processing fee to every residential permit, and a 3% assessment plus the same $10 fee on commercial permits21.

Who is the Trumbull County building department, and how do you reach them?

The Trumbull County Building Inspection Department issues building, electrical, mechanical and plumbing permits for the county12. Reach the office at 159 East Market St., Suite 100, Warren, Ohio 44481, or call (330) 675-24672. The office is open Monday through Friday, 8:00 AM to 4:00 PM, with inspectors generally available for questions from 8:00 AM to 10:00 AM2. If your project touches a water heater, plumbing or septic, the department's own permit page sends you to the county Health Department first, at (330) 675-2489116.

Does Trumbull County have zoning?

No, not countywide. Zoning in Trumbull County is handled at the local level, and the county Planning Commission's role is advisory only, offering recommendations to the unincorporated townships rather than regulating them directly34. Only four townships have no zoning at all: Brookfield, Mecca, Mesopotamia and Vernon; every other township in the county has adopted its own4. Because zoning is set township by township, the rules on setbacks, RVs, tiny homes and manufactured homes for your land depend entirely on which township it sits in, not on any countywide rule4. To find your township's zoning contact, ask the Trumbull County Planning Commission for the current township officials directory, since it lists every township's zoning inspector4.

How do septic permits work in Trumbull County?

Septic systems, called sewage treatment systems (STS) under Ohio law, are permitted locally by the Trumbull County Health Department56. Ohio requires that permit before you install, alter or replace a system, and Trumbull County's own building department tells applicants to clear septic with the Health Department before applying for a zoning or building permit513. Reach the Health Department at 176 Chestnut Ave. NE, Warren, Ohio 44483, or call (330) 675-24896. Statewide rules require a site review with a soil evaluation as part of that permit, plus a follow-up inspection of the finished system within 12 months of approval1314. Soils are a real limiting factor here: none of Trumbull County's soils rate free of severe limits for a conventional drain field in the USDA soil survey, so expect the county to lean on engineered or alternative systems on most sites7.

Can you live in an RV or tiny home on your land in Trumbull County?

This depends entirely on which township your land is in, since Trumbull County itself has no zoning to answer the question34. Statewide, Ohio only regulates RV occupancy inside licensed campgrounds, where a site must be at least 1,000 square feet and hold no more than one RV plus two portable camping units; that rule does not cover living in an RV on your own private land15. A manufactured home installed in Trumbull County cannot be occupied until a state inspector issues an inspection seal, which is paid for when the installation permit is issued10. Whether your specific township allows an RV or manufactured home as a residence, and what its minimum size or setback rules are, is a question for that township's zoning inspector, not the county4.

Building a home in Trumbull County: the steps, in order

  1. Confirm your township and whether it has zoning; contact that township's zoning inspector before you buy, since all but four townships (Brookfield, Mecca, Mesopotamia and Vernon) have zoning4.
  2. If your land division would create a parcel under 5 acres, or opens a new street or easement, it counts as a subdivision under Ohio law and needs county approval before you can build on it9.
  3. Apply for your septic (STS) permit at the Trumbull County Health Department, 176 Chestnut Ave. NE, Warren, before you apply for a zoning or building permit65.
  4. Apply for your building permit at the Trumbull County Building Inspection Department, 159 East Market St., Suite 100, Warren; budget for a 1% state assessment plus a $10 processing fee on a residential permit2.
  5. If your driveway connects to a county road, contact the Trumbull County Engineer's office about a culvert or access permit; if it connects to a township road, ask the township instead16.
  6. Once plans are approved, construction must start within 12 months or the approval expires, so keep the project moving17.
  7. If you're placing a manufactured home, budget for the state inspection seal before anyone can move in10.

What to check before you buy land in Trumbull County

Zoning: find out which of Trumbull County's 24 townships your parcel is in and whether that township has zoning, since only Brookfield, Mecca, Mesopotamia and Vernon have none416. Soils: none of Trumbull County's soils rate free of severe limits for a conventional septic drain field, so budget for a soil evaluation and likely an engineered system7. Water: a private well needs a permit from the local health district before you drill, alter or seal it18. Access: the Trumbull County Engineer's office maintains 462 miles of county roads, 378 bridges and 1,601 culverts across the county's 24 townships, five cities and six villages, but a driveway onto a township road is the township's call16. Taxes: Trumbull County's typical effective property tax rate is about 1.4%, with a median annual bill near $1,8061920.

Watch-outs

  • Trumbull County has no countywide zoning, so a parcel's rules on RVs, tiny homes, setbacks and manufactured homes come from its township, not the county; only Brookfield, Mecca, Mesopotamia and Vernon townships have no zoning at all4.
  • Trumbull County's own sources don't confirm an owner-builder exemption; check directly with the Building Inspection Department before assuming you can act as your own contractor8.
  • Get your septic permit from the Trumbull County Health Department before you apply for a zoning or building permit -- the county's own building department says to clear septic first511.
