Do I need a permit in Montgomery, Ohio?
Montgomery, Ohio follows the Ohio Building Code (currently the 2020 edition with state amendments), which tracks closely to the International Building Code. Most residential projects — decks, sheds, fences, additions, electrical work, plumbing — require a permit from the City of Montgomery Building Department. A few smaller projects are exempt, but the exemptions are narrower than many homeowners expect. The city sits in Climate Zone 5A with a 32-inch frost depth, which affects deck footing and foundation requirements. The good news: Montgomery's permit process is straightforward, fees are moderate, and the building department is responsive to questions. The bad news: skipping a permit can create serious problems when you sell, and inspections are mandatory for most structural work. This page walks you through what requires a permit, what doesn't, how much it costs, and how to file.
What's specific to Montgomery permits
Montgomery uses the 2020 Ohio Building Code, which means code citations you find online will often reference the International Building Code (IBC) and International Residential Code (IRC) — Ohio typically adopts these codes with minor state-level amendments. When you pull a building code book or call the city, you'll hear references to both the state code and the IBC/IRC section numbers interchangeably. For practical purposes, if a national code applies, it applies here.
Frost depth in Montgomery is 32 inches, which is deeper than the IRC's baseline 36-inch assumption but common for Ohio. That means deck footings, shed foundations, and fence posts all need to go down at least 32 inches in undisturbed soil — deeper in areas with poor drainage. The city's soils are glacial till and clay (with sandstone east of the city center), which drains slowly; inspectors are strict about footing depth and compaction. Rushing this during inspection season can mean a failed inspection and delay.
Montgomery allows owner-builders to pull permits for owner-occupied residential projects, including additions, decks, and interior remodeling — but only if you're the property owner and the work is on your primary residence. You cannot pull a permit as a non-owner contractor. If you hire a contractor, the contractor must pull the permit and sign off on the work. Electrical and plumbing work by a non-licensed homeowner is prohibited in Montgomery under Ohio law; you'll need a licensed electrician and licensed plumber, or the city will reject the permit application.
The city processes most residential permits over-the-counter or by mail within 1–2 weeks for straightforward projects (decks, fences, sheds under 200 square feet). Plan-review permits (additions, significant remodels, multi-story work) take 3–4 weeks. Inspections are typically available within 2–3 business days of request during the spring and summer; winter may be slower. The building department does not currently offer a full online portal as of this writing — you'll likely file in person at City Hall or by mail. Before starting any project, call the building department to confirm current filing procedures.
Common rejections in Montgomery stem from missing site plans (showing property lines and setbacks), no proof of property ownership, and undersized or misaligned footings. If you're working near a property line, bring a survey or have one made; the city requires proof that your deck, shed, or fence meets setback rules. Electrical permits are rejected if the homeowner tries to pull them instead of a licensed electrician. Plumbing permits are rejected if rough-in inspections aren't requested before walls are closed. Plan ahead.

Ohio context for Montgomery permits
Ohio adopts the International Building Code and International Residential Code every three years (currently 2020 edition). The state code is enforced uniformly across Ohio, but individual cities like Montgomery can adopt amendments that are more strict — they cannot be less strict. Ohio law also requires that electrical work be performed or supervised by a licensed electrician, and plumbing work by a licensed plumber (with limited exceptions for simple homeowner repairs). Owner-builders can do most structural and carpentry work on owner-occupied homes, but cannot do electrical or plumbing. Montgomery follows this statewide rule strictly. Ohio's frost depth varies by region; Montgomery's 32 inches is typical for the southwestern part of the state. If you're moving from another state or city, confirm local frost depth and soil conditions with the building department — they often have geotechnical data on hand.
Common questions
Do I need a permit for a deck in Montgomery?
Yes. Any deck attached to the house or over 200 square feet, or any deck with stairs or railings, requires a permit in Montgomery. Even simple ground-level decks on the side of the house usually need one — call the building department if you're unsure. The permit covers frost-depth footing inspection, attachment to the house, and railing code. Cost is typically $75–$200 depending on deck size.
What about a shed or small outbuilding?
A shed under 200 square feet and not used for human occupancy (storage only) is often exempt if it's a single story and not attached to the house. A shed over 200 square feet, or any accessory building with a loft or sleeping space, requires a permit. Decks attached to sheds require a permit even if the shed itself is exempt. Setbacks from property lines are strict — Montgomery enforces front, side, and rear setbacks. Always verify setback rules before building; a misplaced shed can trigger a forced removal.
Do I need a permit for a fence?
Most residential fences require a permit in Montgomery. Common exempt cases: a simple wire or chain-link fence under 4 feet (rear or side yard only) with no gates. Anything over 4 feet, a fence in the front yard, or a masonry or solid fence typically needs a permit. Pool barriers always require a permit, even at 4 feet. Fence permits cost $50–$100 and usually approve within a week. The biggest gotcha is setback — a fence that sits on or crosses a property line can be flagged. Get a survey or have your property lines marked before digging post holes.
Can I do electrical work myself?
No. Ohio law prohibits homeowners from pulling electrical permits on their own property — electrical work must be performed or supervised by a licensed electrician. The electrician pulls the permit and signs for the work. This applies even to simple work like adding an outlet, hardwiring a dishwasher, or installing a ceiling fan. Plan to hire a licensed electrician and factor the permit fee (typically $25–$50 for a small job) into your budget. The electrician will handle it.
What's the cost of a typical residential permit in Montgomery?
Most residential building permits are priced as a percentage of project valuation. A $5,000 deck might cost $75–$150 in permit fees; a $20,000 addition might cost $300–$500. Electrical permits are often flat fees ($25–$50). Plumbing permits run $40–$75. Fence permits are typically $50–$100. There's usually no additional plan-review fee for routine projects. Complex projects (additions with structural changes, major renovations) may incur a separate design-review or engineering fee — ask the building department upfront.
How long does a permit take to get approved?
Over-the-counter permits (fences, simple decks, sheds) typically issue within 1–2 weeks if paperwork is complete. Plan-review permits (additions, multi-level work) take 3–4 weeks. Once a permit is issued, inspections are usually available within 2–3 business days during peak season (May–September); winter inspections may take longer. Inspection failures (bad footing depth, missing flashing) require a re-inspection, which adds 1–2 weeks. Submit complete applications with site plans and property-line documentation on the first try to avoid delays.
Do I need a site plan?
Yes, for most permits. A site plan shows the property outline, all structures on the property, property-line setbacks, and the location of the new work. For a simple fence or shed, a hand-drawn sketch works. For a deck or addition, a plan drawn to scale with dimensions is usually required. The building department can provide a site-plan template. This is the #1 reason permits get bounced — missing or incomplete site plans. Spend 30 minutes drawing an accurate site plan; it will save you 2 weeks of resubmission.
What if I build without a permit?
The city can issue a stop-work order, require you to remove the work, or issue a fine. If you sell the house, an inspection or appraisal may uncover unpermitted work, killing the sale or forcing you to apply for a retroactive permit (more expensive and time-consuming). Insurance may not cover damage to unpermitted structures. Lenders routinely pull permits as part of due diligence. The risk is not worth the time saved. Get a permit.
