Middletown, Ohio Building Permit Guide

Building permits in Middletown are issued by the city’s Building Inspections division, One Donham Plaza, Middletown, OH 45042 (513-425-7973), open Monday to Friday 8 a.m. to 4:30 p.m. No online permit portal is listed: permits and applications are emailed to BZPermits@cityofmiddletown.org or delivered to the Community and Economic Development Department on the 3rd floor of One Donham Plaza, and all fees are paid at submission.

This guide covers Building Inspections, Planning and Zoning and the Board of Zoning Appeals. It does not cover the city’s general building permit fee table or how to request inspections; ask the Building Inspections division for both.

What requires a building permit in Middletown?

Ohio’s building codes are statewide; what changes in Middletown is which office handles the address and what that office asks for on top.

Alongside the building permit, Middletown requires a Certificate of Zoning Compliance, typically issued within 10 days. New home construction must also be approved by the Architectural Review Board before permits can be issued, and a dumpster or materials placed in the street need a Use of Right-of-Way permit.

Permits in Middletown 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 Middletown?

Middletown lists the codes it enforces as the 2024 Ohio Building Code, 2019 Residential Code of Ohio, 2024 Ohio Mechanical and Plumbing Codes, 2023 National Electric Code, 2015 International Fuel Gas Code, 2017 International Energy Conservation Code, NFPA 13 and NFPA 72.

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

Local rules in Middletown

Residential applications

New construction needs two sets of plans, and a new building on a vacant lot needs a professionally surveyed site plan. Once plans are approved, the permit fee must be paid and the permit obtained within thirty (30) days or the application is cancelled; the application expires 12 months after plan approval if no permit is issued.

Commercial applications

Commercial building permit applications need three sets of plans stamped by a licensed architect or engineer.

Trade registration

Everyone working on a job site in the regulated trades must hold a master, journeyman or apprentice registration from the Division of Building Inspection. A master registration needs a State of Ohio certificate, $300,000 insurance and a $200.00 fee; journeymen pay $50.00 and pass a city exam. No more than 5 registered apprentices may be on a site per master or journeyman.

A $10,000 performance bond is required for all underground utility contractors and any plumber working in the right-of-way; water service and sewer permits are not issued without it.

Zoning

Zoning follows the Middletown Development Code, effective October 17, 2025. The Board of Zoning Appeals hears appeals of decisions by the Development Code Administrator, Planning Commission or Historic Commission.

Using the street

Material placed under a Use of Right-of-Way permit may extend no more than one-fourth of the width between the curbs, and the engineering department must give special permission to use any part of a traffic lane.

A Board of Building Standards assessment of 3 percent (nonresidential) or 1 percent (residential) is added to local fees. How Ohio permit fees work

How to get a building permit in Middletown

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 Middletown

When construction or remodeling is complete, a Middletown inspector approves the final project and issues a certificate of occupancy. The division can email you when a permit is finalized: send your name, email address and the permit address to request this.

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
