Here's the part of the deck-permit process that trips up most Delaware County homeowners: there are two separate approvals, run by two different offices. The building permit (structure, footings, inspections) is handled countywide by the Delaware County Department of Building Safety and works the same everywhere. Zoning — the setbacks and accessory-structure rules that decide where your deck can legally sit — is set by your township, and it varies from one township to the next. This guide explains what changes by township and which one covers your community.
We handle both steps for you. When Sunbury Decks & Patios builds your deck, we confirm your township, submit the zoning paperwork, and pull the Delaware County building permit — so the setbacks are right the first time. For the fees and inspection schedule, start with our Delaware County deck permit guide.
What the county handles (the same everywhere)
The Delaware County Department of Building Safety issues the building permit, reviews your deck plans, and runs the post-hole, frame, and final inspections. The fees and the frost-depth footing requirement don't change by township — see the permit guide for the fee schedule and how deep footings go in Ohio.
What the township handles (this is what varies)
Each township adopts its own zoning resolution, so the rules that differ locally are typically:
- Rear- and side-yard setbacks — how far the deck must sit from your property lines.
- Lot coverage — how much of the lot all structures combined can occupy.
- Easements — drainage and utility easements a deck can't encroach on (common along the back of newer subdivision lots).
- Accessory-structure rules — how attached decks, detached platforms, and roof-covered porches are each classified.
Exact setback distances and coverage limits differ by township, zoning district, and your subdivision's plat — always confirm the numbers for your specific lot rather than assuming.
Which township (or city) covers your community
| Community | Zoning authority |
|---|---|
| Sunbury (city) | City of Sunbury zoning; county building permit since Oct 2022 |
| Areas around Sunbury | Berkshire Township / Trenton Township |
| Galena (inside village limits) | Village of Galena — its own zoning authority |
| Galena mailing address, outside the village | Whichever township the parcel sits in (Berkshire, Berlin, Genoa, Harlem or Trenton) + HOA review |
| Powell (unincorporated) | Liberty Township |
| Lewis Center | Orange Township |
| Hoover-area / south | Genoa Township |
| Rural county outside the growth corridor | Kingston, Porter, Harlem or Brown Township |
| Delaware (city) | City of Delaware zoning & building review |
Not sure which one you're in? Your parcel record lists the township, and the Delaware County Regional Planning Commission publishes a directory of each township's zoning officer. We confirm it for every project so nothing gets built over a setback line.
Berkshire & Trenton Townships (Sunbury area)
Most of the unincorporated land around Sunbury falls in Berkshire Township — the fast-growing I-71 / US-36 corridor — or Trenton Township. Zoning here runs through the township even though building permits go to the county.
Genoa Township (Hoover / southern county)
Genoa Township covers the Hoover-reservoir-area neighborhoods in the south of the county. Like the others, it sets its own setbacks and administers its own zoning permit.
Orange Township (Lewis Center) & Liberty Township (Powell)
Lewis Center sits in Orange Township, and the unincorporated Powell area is largely Liberty Township — two of the county's densest residential townships, where mature subdivisions and tight easements make the setback check especially worth doing before you design.
A “Galena” address is not a zoning jurisdiction
Galena is where this trips up the most homeowners, and it's worth spelling out. The Village of Galena is its own zoning authority — the Delaware County Regional Planning Commission lists it alongside the cities and villages, not under a township. But the Galena 43021 mailing address covers far more ground than the village limits, and those outlying parcels are zoned by whichever township they actually sit in — which, depending on the parcel, can be Berkshire, Berlin, Genoa, Harlem or Trenton Township.
So two houses that both say “Galena, OH” on the mail can answer to two completely different zoning offices with different setbacks. That's the case in the big-lot communities like Vinmar Farms, Cheshire Woods, and Harbor Pointe, where an HOA architectural review sits on top of whichever zoning applies. Check the parcel record for your address before you design — don't assume your mailing address, or your neighbor's answer, settles it.
Kingston, Porter, Harlem & Brown Townships (the rural tier)
Beyond the Sunbury and Galena growth corridor, much of the rest of the county is covered by smaller rural townships — Kingston, Porter, Harlem and Brown among them. The structure is identical to the busier townships: the county still issues the building permit and runs the inspections, and the township still sets the setbacks and accessory-structure rules. What differs in practice is that larger rural lots make property-line setbacks far less likely to bind, while septic systems become the real constraint — a deck can't be built over a leach field or the area reserved to replace it, and that placement check matters more here than the setback math does.
These smaller townships also tend to run limited zoning-office hours, so build extra lead time into the schedule. As everywhere in the county, confirm the current requirements for your specific parcel rather than assuming they match a neighboring township.
HOA architectural review — a separate third layer
In most Galena and Sunbury new-build subdivisions there's a third approval on top of township zoning and the county permit: HOA architectural review (ARC). It governs materials, colors, and railing styles, not code — but it can add lead time. See our HOA deck-approval guide for how that submittal works.
