Do you need a building permit in Columbus Grove, Ohio?

Yes. The Columbus Grove code says no person may erect, convert, demolish, alter, enlarge or move any building or structure without first obtaining a building permit¹. The permit fee is $1.00 per $1,000.00 of construction, with a $25.00 minimum and a $500.00 maximum⁶.

Applications are written, on approved forms, with two sets of dimensional plans and specifications for the materials¹². The Zoning Enforcement Officer examines the submission and may waive plan filing for minor work that the application adequately describes¹². The village website posts a building permit application and asks that permits be returned to the village office for review⁴.

The county's rules for unincorporated land do not apply here. Putnam County directs building-permit questions to the village for property inside corporation limits and to the township outside them¹³.

Who issues building permits in Columbus Grove, and how do you reach them?

The Village of Columbus Grove issues building permits itself; Putnam County has no single county building department for this¹³. The village website lists the Village Administrator at 419-659-2982 and [email protected]⁴. The code names the Zoning Enforcement Officer as the person who examines permit applications¹². Ask the village office who currently holds that role and which form to use.

We could not confirm whether the village adopts a named building code or requires inspections or a certificate of occupancy. Ohio's residential building code is set at the state level¹⁴, so ask the village office how plan review and inspections work for a new house.

Does Columbus Grove have zoning, and what does it mean for lot size and setbacks?

Yes. Columbus Grove adopts its own Planning and Zoning Code, and district and use requirements apply to land inside village limits². The code lists commercial and industrial districts, R-1 through R-4 residential districts, and a mobile-home park district⁵.

In the R-1 Single-Family Residential District, no zoning lot may be smaller than 12,000 square feet or narrower than 80 feet⁷. R-1 setbacks are 30 feet in front, 10 feet on each side and 30 feet in the rear⁸. Maximum building height in R-1 is 35 feet¹⁵. Other districts have their own numbers, so look up the lot's district before buying.

We could not confirm a minimum dwelling size, lot-coverage limit or accessory-dwelling rule for the single-family district; ask the village office. Village zoning replaces the township rules that govern land outside village limits.

Can you put a mobile home, RV or tiny home on a lot in Columbus Grove?

Mobile homes are limited. No mobile home may be placed on a lot that was not previously occupied by one or is not otherwise zoned for them, and a permit is needed to remove or move one in¹¹. A mobile home moved into the village must have a ground floor area of at least 600 square feet, per the code's published minimum¹¹.

Ohio law separately says a permanently sited manufactured home is a permitted use wherever the local government permits single-family homes, though local governments may prohibit mobile homes that do not qualify¹⁶.

We could not confirm village rules on living in an RV, camping or tiny homes. Statewide campground rules cover licensed campgrounds, not a private lot¹⁷. Call the Village Administrator at 419-659-2982 before parking an RV to live in or building a tiny home⁴.

How do septic permits work in Columbus Grove?

Septic permits for property inside Columbus Grove come from the Putnam County Health Department, which conducts permitting, inspections and enforcement³. No individual or contractor may install or alter a sewage treatment system without a permit⁹. Before a permit is issued, all buildable lots need a site evaluation, and some need a soil evaluation by a certified soil scientist¹⁸.

The 2025 sewage treatment system permit fee is $500¹⁹. Once installed, a system needs an operation permit; the 5-year operation permit fee is $75, and the tank must be pumped at least once every 10 years²⁰.

Many village lots connect to public sewer instead, and we could not confirm a village rule on when connection is required. Ask the village office, then call the Environmental Health Division at 419.523.5608 for any lot that will use a septic system²¹. Putnam County's soils rate poorly for conventional drain fields (0% rated not limited), so expect a site evaluation²².

Building a home in Columbus Grove: the steps, in order

Confirm the lot's zoning district in the village Planning and Zoning Code and check lot size and setbacks².
If the lot will not use public water or sewer, contact the Putnam County Health Department first; a private water system needs its own permit¹⁰, and the health department should be involved from the beginning²³.
Get the septic permit and, if used, the well permit before the building permit step; the county's process lists health-department permits ahead of the local building permit²⁴.
Submit the village building permit application with two sets of plans and specifications¹².
Pay the fee, $1.00 per $1,000.00 of construction with a $25.00 minimum and $500.00 maximum⁶.
If you are dividing a parcel, lot splits of 5 or fewer acres go through the Putnam County Planning Commission at 419-523-8758²⁵.

What stays with Putnam County, and what to check before you buy in Columbus Grove?

Septic and private water permits stay with the Putnam County Health Department for every address, village or not³¹⁰. For land outside village limits, see the Putnam County page.

Driveways: the county engineer's permit covers driveways off county roads, ODOT handles state highways and township trustees handle township roads²⁶. We could not confirm a village driveway-permit rule, so ask the village office. Floodplain questions inside village limits go to village officials²⁷.

Taxes: Putnam County's effective property tax rate is 1% and the median bill is $1,870 a year²⁸²⁹.

Watch-outs

Septic and well permits come from the Putnam County Health Department even for lots inside village limits, so the village building permit does not cover them³¹⁰.
The county page's rules apply to unincorporated land; inside Columbus Grove the village code governs building permits and zoning¹³.
We could not confirm village rules on RV occupancy, tiny homes, accessory dwellings, driveways or inspections; call the Village Administrator at 419-659-2982 before relying on them⁴.
Fees and setbacks differ by district and the code can be amended, so confirm the current figures with the village office before you pay or build⁶.
