Richland County, Ohio Building Permit Guide

Building permits across most of Richland County come from the Richland County Building Department at 1495 West Longview Avenue, Suite 202A, in Mansfield. The department serves the townships and, apart from Mansfield, the county’s cities and villages, in Bellville for commercial work only. The City of Mansfield has its own department.

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 areas the county department serves: every township; Butler, Lexington, Lucas, Ontario, Shelby and Shiloh for residential and commercial work; Plymouth for residential work; and Bellville for commercial work. Only Mansfield has its own department, at 30 North Diamond Street (419-755-9688).

What requires a building permit in Richland County?

Under the Ohio Building Code and the Residential Code of Ohio, a permit is required for most construction activity.

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 county's certified departments enforce the statewide Ohio codes, so the technical standard is constant across the county. Fees, submittal processes, zoning frameworks, inspection scheduling and any additional local regulations are what differ between the county department and the municipal ones.

Permits in Richland 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 Richland County?

Permits are issued by the certified department with authority over the address. Zoning is not handled by the building department: check with the local zoning inspector listed on the department’s zoning inspectors page. For unzoned townships, the department points applicants to the Regional Planning Commission or the County Engineer.

In Bellville the county handles commercial work only, and the Board of Building Standards data shows no residential department there, so houses in Bellville need no state or county building permit (ORC 3791.04). Plumbing work is permitted through the local health department rather than the building department.

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.

In 2025, building permits issued in unincorporated Richland County authorized 78 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Zoning is a separate approval, and often a separate office

Zoning is a separate approval. In zoned townships the department needs the approved zoning permit, where one applies, with the application; the zoning inspector for each jurisdiction is listed on the department’s zoning inspectors page.

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

One-, two- and three-family dwellings follow the Residential Code of Ohio. Residential applications go in on paper, in person from 8:00am to 3:30pm or by mail, with at least two sets of drawings. The department’s design criteria are a 36-inch frost depth, a 90 mph wind speed (3-second gust) and a 20 psf ground snow load.

Commercial permits

Commercial buildings, and multifamily buildings of four or more units, follow the Ohio Building Code. Commercial projects can be submitted on paper or through the department’s web portal. Drawings for fire alarms, sprinklers, suppression systems and hoods must be sealed by a registered design professional, and fire protection drawings need at least three sets.

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.

Richland County permit costs and fees

Richland County sets its fees by project type and size. The permit fee covers the application, plan review, all building, electrical and mechanical inspections and the certificate of occupancy; revised drawings, missed inspections, repeat inspections for incomplete work or added square footage can cost extra. 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 Richland 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.

Inspections in Richland County

Schedule inspections with the certified department that issued the permit. The building official lists the required inspections when the plans are approved (OBC and RCO 108.2); they include foundation, framing, rough-in trades, insulation and energy, and final, with a Certificate of Occupancy required before legal occupancy of new or changed-use space. Unsewered parcels add on-site sewage verification.

Call at least one business day ahead to book an inspection; bookings are taken up to a week ahead. Foundation inspections can be booked the same day until 8:30am if the schedule allows. The certificate of occupancy is issued after the final building, electrical and plumbing inspections.

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

Richland 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 Richland County Building Codes 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.

These are the primary sources behind this guide. Codes, fee schedules and portal procedures change. Confirm the position for your filing date.

Frequently asked questions

Where exactly is the office?

At 1495 West Longview Avenue, Suite 202A, Mansfield, in the county’s Longview Center, which it shares with the Board of Elections and the Soil and Water Conservation District. Applications are taken from 8:00am to 3:30pm.

What design loads does the county use?

A frost depth of 36 inches below finished grade, a wind speed of 90 mph (3-second gust) and a ground snow load of 20 psf, according to the department.

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?

The Division of Industrial Compliance performs commercial plan review and inspection where no certified department serves. Residential code enforcement, however, is carried out only by certified local departments, so the fallback is commercial-only.

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.
