Fairfield County, Ohio Building Permit Guide

The Fairfield County Building Department, at 138 West Chestnut Street in Lancaster, issues building permits for commercial buildings only, and only in the unincorporated areas outside Violet Township. It does not regulate one-, two- and three-family dwellings. Violet Township has its own department for commercial and residential work, and cities such as Lancaster and Pickerington issue their own permits. The county had 169,752 people in the Census Bureau’s 2025 estimate, up from 158,917 in 2020.

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 the Fairfield County Building Department, which handles commercial work in the unincorporated areas outside Violet Township, and the position for houses in those areas. Lancaster, Pickerington, Violet Township and the other certified departments issue their own permits.

What requires a building permit in Fairfield County?

Where a certified department has authority, the Ohio Building Code and the Residential Code of Ohio require approval for most construction activity. Houses in the unincorporated townships outside Violet Township need none.

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

Every certified department in the county enforces the statewide Ohio codes. Fees, submittal processes, zoning, inspection scheduling and any additional local regulations are what differ between the county department and the township and municipal ones.

Permits in Fairfield 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 Fairfield County?

Permits are issued by the certified department with authority over the address. Fairfield County has no county-wide zoning: 11 of its 13 unincorporated townships have adopted zoning, as have many cities and villages, and each keeps its own maps and regulations.

The Fairfield Department of Health permits and inspects commercial and residential plumbing and is the authority for private water supplies and sewage. The County Engineer handles county roads, and the Regional Planning Commission handles subdivision and floodplain review.

One point applies across every Ohio jurisdiction and is worth confirming here 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 is a separate approval, from a separate office

Zoning is handled by the township, city or village, not by the county building department. The Regional Planning Commission lists each township’s zoning inspector; ask the inspector about districts, permitted uses and lot requirements, and whether a zoning permit must come before the building application.

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

The county department does not regulate one-, two- and three-family dwellings. Houses in Lancaster, Pickerington, Violet Township and the other places certified for residential work are permitted by those departments. In the unincorporated townships outside Violet Township no building permit is required for them (ORC 3791.04), but township zoning and health department approvals still apply.

Commercial permits

The county’s commercial process runs in four steps: application and submittal of plans, plan review and permit issue, construction and inspection, and final approval with a certificate of occupancy. Since 1 July 2024 it accepts commercial documents electronically only, by email to FCBuilding@fairfieldcountyohio.gov, after a $130 plan review deposit has been mailed by check.

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.

Fairfield County permit costs and fees

The county charges commercial permit fees by floor area under its Commercial Building Permit Application Requirements and Fee Schedule. The $130 deposit is applied toward the final permit fee, and fees are due when the approved plans are received. A Board of Building Standards assessment of 3 percent of nonresidential fees is added (ORC 3781.102). Lancaster, Violet Township and the other departments publish their own schedules.

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 Fairfield 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 Fairfield County

Schedule inspections with the certified department that issued the permit. At the county, the permit, the approved plans and the inspection card must be on site throughout construction, the applicant prints the stamped approved plans, and a certificate of occupancy or certificate of completion is issued after all final inspections are approved. Reinspections cost $70. In Lancaster, inspection requests go to 740-681-5018.

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

Fairfield 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 served the address — the county for commercial work, or Lancaster, Violet Township or another municipal department — what it holds for the parcel and whether earlier records may sit elsewhere.

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

Which department in Lancaster do I need?

It depends on the address and the work. The county department at 138 West Chestnut Street handles commercial work in the unincorporated areas outside Violet Township; the Lancaster Certified Building Department in City Hall, 104 East Main Street, permits work inside the city limits.

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 only where no certified department serves; in unincorporated Fairfield County the county department serves. For one-, two- and three-family dwellings no plan submission is required where no department is certified for residential work (ORC 3791.04), which is the position in the unincorporated townships outside Violet Township.

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.
