Wood County, Ohio Building Permit Guide

Building permits across almost all of Wood County, including Bowling Green, Perrysburg, Rossford and Northwood, come from Wood County Building Inspection at One Courthouse Square in Bowling Green, which is certified for both residential and commercial work. Wood lies immediately south of Lucas County and Toledo on the flat former lake plain of northwest Ohio, and had 134,176 people in the Census Bureau’s 2025 estimate; Bowling Green, the county seat, is home to Bowling Green State University.

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 Wood County Building Inspection serves: the townships and almost every city and village in the county. The parts of Maumee, Toledo and Oregon that lie in Wood County use those cities’ own departments.

What requires a building permit in Wood 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

Wood County Building Inspection enforces the statewide Ohio codes: the Residential Code of Ohio for one-, two- and three-family dwellings and the Ohio Building Code for commercial work. What differs from other Ohio departments is the fee schedule, the submittal process, the zoning framework, inspection scheduling and any additional local regulations.

Permits in Wood 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 Wood County?

Permits are issued by the certified department with authority over the address. Wood County Building Inspection covers residential and commercial construction across Wood County, and commercial construction in Hancock, Henry and Fulton counties too. The cities of Bowling Green, Perrysburg, Rossford and Northwood do not have their own building departments; Perrysburg, for example, issues zoning permits and contracts with the county for building permits. Zoning is administered by the city, village or township.

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 Wood County authorized 161 new privately owned housing units, 99 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

A zoning permit comes first

Before you apply for a building permit, residential or commercial, the county requires a zoning permit from the local zoning authority for the job site. Its website lists the zoning boards and inspectors for most cities and townships, and a few villages have no zoning. In Perrysburg, for example, the city issues the zoning permit, and it must be obtained before the building permit.

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

For one-, two- and three-family dwellings the county issues building, plumbing, heating and electrical permits. New construction, additions and alterations need two sets of drawings with the application and fee. Non-uniformly loaded girders, columns, headers and beams must be backed by an engineer’s or architect’s seal or by engineering calculations, and footings that do not bear on undisturbed soil need a sealed design. Plans are reviewed in the order received.

Commercial permits

Commercial work follows the Ohio Building Code. The county issues commercial building, plumbing, electrical, mechanical, sprinkler and fire-alarm permits, each with its own fee, and charges a separate plan review fee when trade plans are submitted apart from the building review.

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.

Wood County permit costs and fees

Wood County charges by gross floor area. A residential building permit is a $75 base fee plus $0.20 per square foot, counting garage and basement but not crawl space; a commercial building permit is a $125 base fee plus $0.12 per square foot, with plan review at $125 plus $0.02 per square foot. A state fee of 1 percent on residential and 3 percent on commercial permits 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 Wood 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 Wood County

Schedule inspections with Wood County Building Inspection on 419-354-9190 at least 48 to 72 hours ahead; it schedules daily until 3:00pm. The required inspections are footing, foundation, structural, rough and final plumbing, electrical and heating, and a final building inspection before occupancy.

If the inspector cannot inspect because the work is not ready, the site is locked or no approved plans are on site, a re-inspection fee of $75 applies.

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

Wood 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 Wood County Building Inspection 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

What are the counter hours?

Monday to Friday, 7:30am to 3:30pm, on the third floor of the County Office Building at One Courthouse Square, Bowling Green. Inspection requests are scheduled daily until 3:00pm.

Why does drainage matter so much?

Wood County is a former glacial lake bed. The Ohio Department of Natural Resources describes its relief as nearly level to gently sloping and its surface soils as mostly clay-rich, with some very poorly drained soils and a seasonally high water table. Establish the subsurface picture before design.

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.
