Ross County, Ohio Building Permit Guide

The Ross County Building Department at 15 North Paint Street in Chillicothe issues building permits for commercial buildings and multifamily buildings of four or more units outside the City of Chillicothe. It is certified for commercial work only, so houses outside the city need no county or state building permit. The City of Chillicothe runs its own department, which has handled all the city’s residential and commercial permits since 7 July 2025.

This guide covers the department and how to reach it, the local conditions that shape a filing here, what permits cost and who may pull them, and how inspections are booked. Rules that apply everywhere in Ohio are summarized in each section, with a link to the full statewide explanation.

This guide covers Ross County outside the City of Chillicothe, where the county department handles commercial work, and notes the City of Chillicothe Building Department (35 South Paint Street, 740-773-8980) where it differs.

What requires a building permit in Ross County?

Where a certified department has jurisdiction, the Ohio Building Code and the Residential Code of Ohio require approval for most construction. In Ross County outside Chillicothe that means commercial buildings and multifamily buildings of four or more units; inside Chillicothe it also means houses.

The exempt list is set statewide in Section 102.10 of the Ohio Building Code and the Residential Code of Ohio, and an exemption from a building permit is not an exemption from zoning, setbacks, floodplain rules, utility approval or a fire authority review. Confirm scope with the department before work starts rather than after.

Which code edition applies

The Ross County Building Department enforces the Ohio Building Code; the City of Chillicothe Building Department enforces both the Ohio Building Code and the Residential Code of Ohio. The technical standard is statewide. Fees, submittal processes, zoning, inspection scheduling and any additional local regulations are what differ.

Permits in Ross County are governed by Ohio’s statewide codes: the Ohio Building Code for commercial and other nonresidential buildings, and the Residential Code of Ohio for detached one-, two- and three-family dwellings. The Ohio Building, Mechanical and Plumbing Codes in force since 1 March 2024 are based on the 2021 International Codes; the Residential Code of Ohio is the 2019 edition, based on the 2018 International Residential Code; both use the 2023 National Electrical Code. Only departments certified by the Ohio Board of Building Standards may approve plans, and residential rules are uniform statewide. How Ohio’s statewide code works

Who handles permitting in Ross County?

The Ohio Board of Building Standards certifies the Ross County Building Department for commercial work only. It covers the unincorporated county and, in the Board’s records, the villages of Adelphi, Bainbridge, Clarksburg, Frankfort and Kingston. The City of Chillicothe department is certified for residential and commercial work.

Commercial plumbing permits in Ross County, including Chillicothe, are submitted to the Ross County Health District, not to the building department. The City of Chillicothe does not currently issue residential plumbing permits.

On unsewered parcels the board of health must approve the sewage treatment system after a site evaluation (ORC 3718.02), and a new private well needs a board of health permit (OAC 3701-28-03). Resolve both before a layout is fixed.

One point applies across every Ohio jurisdiction and is worth confirming rather than assuming. Residential rules are uniform statewide: a local code may differ from the Residential Code of Ohio only on subject matter the state code does not address, or after review by the Board of Building Standards (ORC 3781.10, 3781.01). Municipalities may add nonresidential regulations that do not conflict with the state rules. Ask the issuing department whether any local regulation affects your project type.

Zoning and land development

The county building department lists zoning in Ross County for the Ross County Airport hazard area, which it administers itself, the City of Chillicothe, and Buckskin and Deerfield townships. Subdivision and other development review in the unincorporated county goes to the Ross County Planning Commission through the Planning and Development Department. A new driveway on a township or county road needs an access permit from the county building department, which also issues the address; on US and state highways the driveway permit comes from ODOT.

The Ohio Board of Building Standards certifies which departments may enforce the code, and for which buildings; the certified department’s political subdivision sets fees, and zoning is a separate approval. Where no certified department has jurisdiction, nonresidential plans go to the state, while houses need no plan submission. The Board’s building-department look-up shows which department has authority over an address. Who has authority in Ohio

Permit types

Residential permits

Outside Chillicothe no department is certified for residential work, so one-, two- and three-family dwellings need no state or county building permit (ORC 3791.04). Floodplain, zoning, access and board of health approvals still apply where the parcel needs them. Inside Chillicothe the city building department reviews residential plans, inspects, issues occupancy permits and registers the contractors who work in the city.

Commercial permits

Commercial buildings and multifamily buildings of four or more units outside Chillicothe need a permit from the county department. Since 1 August 2024 all nonresidential plan review applications are emailed to the department; it accepts no paper copies or thumb drives. The department puts plan review at about 30 days, and expedited review can be requested for an additional fee. Its fees are non-refundable.

Two statewide topics shape most Ohio submittals: energy compliance (the 2021 IECC or ASHRAE 90.1-2019 for commercial buildings, Chapter 11 of the Residential Code of Ohio for houses) and work on existing buildings, where alteration, repair, addition and change of occupancy each carry their own requirements.

Ross County permit costs and fees

Fees are set by whichever certified department issues the permit, and a Board of Building Standards assessment of 3 percent of nonresidential and 1 percent of residential fees is added (ORC 3781.102).

Fee schedules are revised on each jurisdiction’s own cycle, so ask the issuing department for the schedule in force on your filing date, and ask separately about plan review, trade, re-inspection and revision charges. A Board of Building Standards assessment of 3 percent (nonresidential) or 1 percent (residential) is added to local fees. How Ohio permit fees work

Trade permits and who may pull them

Ohio licenses five commercial trades statewide through the Ohio Construction Industry Licensing Board: electrical, HVAC, hydronics, plumbing and refrigeration. The state does not license general or residential contractors, so those are licensed or registered locally, if at all. Home construction contracts of $25,000 or more must be in writing under ORC 4722. Contractor licensing in Ohio

How to apply for a Ross County building permit

Approved plans become invalid if work has not started within twelve months, with one twelve-month extension available. Before filing, confirm the department has authority over the address for the work, whether the Ohio Building Code or the Residential Code of Ohio governs, and which approvals must be in hand first. Review and corrections in Ohio

Inspections in Ross County

Schedule inspections with the department that issued the permit; in Chillicothe, call 740-773-8955 at least 24 hours ahead. The building official lists the required inspections when the plans are approved (OBC and RCO 108.2), and a certificate of occupancy is required before a new or changed-use building is occupied (OBC 111, RCO 111.1).

Confirm the work is complete and observable before booking an inspection.

No building may be occupied until a certificate of occupancy or completion is issued, and a change of occupancy needs approved construction documents even without other work. Address correction notices before requesting a re-inspection, and do not cover work before it has been inspected and approved. Inspections and occupancy in Ohio

Ross County permit search and official resources

Permit records sit with the department that issued them, which in Ohio makes record research a certification question first. A property may have records with a municipal department, a county department, a township department or the state, depending on who held authority at the time the work was done — and that can have changed if a department gained or gave up certification, or if the property was annexed. If you are buying, refinancing or renovating, ask the department that covers the parcel what it holds. Until 7 July 2025 the Ross County Building Department inspected commercial work inside Chillicothe, so older commercial records for the city may sit with the county.

The Board's building-department lookup helps here too: it establishes who has authority today, which is the right starting point even when the history is more complicated.

Frequently asked questions

What is the substantial improvement threshold?

In a special flood hazard area in unincorporated Ross County, the owner or contractor of an existing building that will be renovated, repaired, improved or added to must give a cost estimate before permits issue. Depending on the cost, the year built and the location, the addition or the whole building may have to meet the elevation or floodproofing standards of the county’s floodplain regulations.

How do I know which department issues my permit?

Use the Board of Building Standards building-department lookup, which maps an address to the department with authority over it. Only a BBS-certified department, or the state, may approve plans and issue permits, and certification does not follow automatically from being a city, county or township.

Does my project fall under the OBC or the RCO?

Commercial, industrial and public buildings follow the Ohio Building Code. One-, two- and three-family dwellings follow the Residential Code of Ohio. Ohio’s residential code reaches three-family dwellings, where the International Residential Code stops at two.

What if no certified department serves the area?

Commercial plans go to the state Division of Industrial Compliance where no certified department serves (ORC 3791.04). Where no department is certified for residential work, as in Ross County outside Chillicothe, no residential plan submission is required.

Does my general contractor need an Ohio licence?

There is no statewide general-contractor licence in Ohio. The state licenses five commercial trades through the OCILB — electrical, HVAC, hydronics, plumbing and refrigeration — while general contractors, and trade contractors on residential work, are licensed or registered only where a local government requires it. Home construction and improvement contracts of $25,000 or more on one-, two- and three-family dwellings must be in writing under ORC 4722, and the supplier must carry at least $250,000 of general liability insurance.

How long is my approval good for?

Approved construction documents are valid where work commences within 12 months, with one 12-month extension available under Section 105 of the Ohio Building Code and the Residential Code of Ohio. Confirm the position with the issuing department before an approval is allowed to age.
