60Index Score / 100 #26 of 88 in Ohio
Brown County, Ohio requires a building permit for new one-, two- and three-family homes, additions, attached garages, and detached garages over 200 square feet, issued by the county Building Department1. A local zoning permit comes first, and zoning is set by townships such as Perry and Eagle, not by one countywide office234. Septic and private-well permits come from the Brown County Health Department56.

Do you need a building permit in Brown County, Ohio?
Yes. Brown County requires a residential building permit for one-, two- and three-family dwellings, additions, attached garages, detached garages exceeding 200 square feet, structural remodeling, and residential demolition1. The Building Department administers the current Residential Code of Ohio for this covered work11. The Building Department issues the county building permit, while zoning permits and septic permits come from other offices. The permit is issued after plan approval, and the application package includes two plan sets, the fee, and the listed health, planning, zoning, driveway, flood, and septic or plumbing approvals that apply to the project7. Published fees for new residential construction, additions, garages, and accessory buildings run from $250 to $650 by project size, with the $100 plan-review and processing fee included12. Brown County says its department no longer permits or inspects manufactured homes; an Ohio-regulated manufactured home generally cannot be occupied until an inspector issues the state inspection seal1314.
Who issues Brown County building permits, and how do you reach them?
The Brown County Building Department issues residential building permits and conducts the associated plan review and inspections13. The office is at 800 Mt. Orab Pike, Suite 111, Georgetown, Ohio 45121, and its phone number is (937) 378-471613. Published weekday hours are 7:30 a.m. to 4:00 p.m., with a closure from 12:30 p.m. to 1:00 p.m.13. The county page says to submit two sets of plans and the fee; the building permit follows plan approval13. For new homes and additions, request inspections 24 hours ahead, and expect foundation, slab or under-floor, framing and mechanical, any applicable fireplace, and final stages15. The final building inspection requires final electric, plumbing, and septic approvals15.
Does Brown County, Ohio have zoning?
A local zoning permit is required before a Brown County residential building-permit application, so do not assume an unincorporated parcel has no zoning rules2. Zoning is township-by-township: Perry Township has zoning regulations, requires a zoning permit for all permanent structures and for portable buildings or sheds over 200 square feet, and lists a zoning permit fee of $0.20 per square foot3. Eagle Township also has a township zoning inspector4. Other townships' current districts could not be confirmed; ask the Building Department which zoning authority serves the parcel and get written answers on allowed use, minimum dwelling size, RV occupancy, and accessory dwellings213. In an unincorporated residential subdivision where no county or township zoning resolution applies, minimum lot area depends on public-water and central-sewer availability and ranges from 9,450 square feet to 1 acre16. Front setbacks also vary by street type and utility service17. Limited zoning controls can apply to certain agricultural uses or structures on tracts of five acres or less18.
How do septic and well permits work in Brown County?
A Brown County Health Department permit is required to install, repair, or abandon a household wastewater treatment system5. The property owner obtains the application, the Health Department evaluates the property, and a registered installer applies for the installation permit19. Ohio requires a site review before a new, replacement, or altered sewage-system permit; the review generally includes a soil evaluation and system design9. Only 0.7% of county soils are rated without severe limitations for a conventional septic drain field, so make the soil report and approved system design a purchase contingency rather than assume a conventional field will work20. The completed installation must be inspected and approved before it is covered, and all applicable inspections must be approved before the home is occupied5. The Health Department also requires a permit to install or repair a private water system, including a well or cistern6.
Can you live in an RV or tiny home on your land in Brown County?
Brown County's private-land RV occupancy rule could not be confirmed, and the statewide campground rule does not answer whether you may live in an RV on your own parcel. Ohio's rule governs licensed and temporary campgrounds, where a compliant site generally has at least 1,000 square feet and may contain one recreational vehicle plus two portable camping units21. For private land, ask the zoning authority serving the parcel whether residential RV use or temporary construction occupancy is allowed, then ask the Health Department what sanitation approval is required222. Brown County also has no confirmed countywide tiny-home occupancy or minimum-dwelling-size rule in the available material. A site-built tiny home that falls within the county's residential building scope still needs building review, while a manufactured home follows Ohio's inspection-seal process and is not permitted or inspected by the county Building Department11314.
Building a home in Brown County: the steps, in order
Identify the zoning authority for the parcel and obtain the local zoning permit required before the residential building application2.
Obtain Brown County Planning Commission subdivision approval when the project involves a subdivision23.
Arrange the Health Department's property evaluation, soil work, septic process, and any private-well or cistern permit196.
Obtain Brown County Engineer approval for the driveway curb cut and address, and obtain the applicable jurisdiction's flood permit if the site is in a flood-zone area2425.
Submit the plans, fee, and applicable approvals to the Brown County Building Department; the county issues the building permit after plan approval7.
Request building inspections 24 hours ahead, and have the septic installation approved before it is covered1526.
Complete final electric, plumbing, and septic approvals before the final building inspection and occupancy1526.
What should you check before buying land in Brown County?
Start with legal use: identify the parcel's local zoning authority and get written answers on the proposed home, temporary RV stay, setbacks, lot size, and accessory structures before closing2. If the tract is in an unincorporated residential subdivision without an effective county or township zoning resolution, confirm the subdivision table's utility-dependent lot area and front setback with the Planning Commission1617. Make septic feasibility a central due-diligence item because only 0.7% of Brown County soils are rated without severe limitations for a conventional drain field20. Ask the Health Department to explain the site evaluation, soil report, system design, inspection sequence, and private-water permit the tract will need19266. Verify driveway approval and identify the jurisdiction that issues the required permit if the property is in a flood-zone area2425. Brown County's effective property-tax rate is about 0.8%, and its median annual property-tax bill is about $1,4972728.
Watch-outs
A local zoning permit must come before the Brown County residential building application2.
Conventional septic conditions are difficult across nearly all of Brown County, with only 0.7% of soils rated without severe drain-field limitations20.
Brown County no longer permits or inspects manufactured homes; Ohio generally requires the state inspection seal before occupancy1314.
A flood-zone site needs a permit from the applicable jurisdiction, but the county checklist does not identify that issuing jurisdiction25.

county zoning authorityGeneral
County commissioners may adopt zoning resolutions regulating building, structures, land uses, and districts or zones in unincorporated territory statewide.
The authority is exercised by resolution and must be in accordance with a comprehensive plan.
The authority applies to unincorporated territory of the county.
The statute begins with the exception phrase “Except as otherwise provided in this section,” so the limitations in ORC Chapter 303 apply.
For nonresidential property only, the county may regulate height, bulk, number of stories, size, lot coverage, yards, courts, open spaces, and population density.
Agricultural uses and agricultural buildings are subject to the limitations in ORC 303.21; the statute also contains limitations for public utilities, railroads, telecommunications towers, alcoholic-beverage sales, oil and gas drilling, and permanently sited manufactured homes.
Activities regulated under ORC Chapters 1513 and 1514 may be regulated only in the interest of public health or safety, and Chapter 1514 activities must be provided for as permitted or conditional uses as specified by ORC 303.02.
“the board of county commissioners may regulate by resolution, in accordance with a comprehensive plan”
county building authorityGeneral
County commissioners may adopt and enforce local residential building regulations in unincorporated areas and may operate certified county building departments that enforce state residential and nonresidential building codes, accept and approve plans, and conduct inspections.
Local residential building regulations may be enforced within the unincorporated area or within districts established in the unincorporated area.
A local residential building regulation may not differ from the state residential building code unless it addresses subject matter not addressed by that code or is adopted under ORC 3781.01.
An existing structures code must concern subject matter not addressed by, and may not conflict with, the state residential building code.
County building departments may enforce state codes only for the types of buildings and subject matters for which they are certified.
Certification permits enforcement authority, plan approval, and inspections; the certification application identifies whether it covers residential or nonresidential buildings and whether residential certification covers new construction only or also repair and alteration.
The board may adopt flood-hazard, Lake Erie coastal-erosion, and drainage regulations, subject to the statutory limits and exceptions in ORC 307.37.
Local regulations, codes, or amendments require public hearings at not fewer than two regular or special board sessions; they take effect on the thirty-first day after adoption.
Regulations adopted under ORC 307.37 generally do not affect buildings or structures existing, or under construction, before adoption, except as provided for an existing structures code.
The state residential building code is effective as a uniform requirement in areas with a building department certified to enforce it.
