If you live in Anderson Township, Newtown, or one of the unincorporated neighborhoods in northeast Hamilton County, your deck permit doesn’t come from a city building department — it comes from the Hamilton County Planning + Development Department. The county’s Buildings + Inspections Division handles building permits for all unincorporated townships, while each township manages its own zoning separately.
That two-agency structure is the most important thing to understand before you start. You need a zoning certificate from your township first, and then a building permit from the county. This guide walks you through both steps.

Step 1: Get Your Zoning Certificate from Anderson Township
Before you can apply for a building permit, you need a zoning certificate from Anderson Township confirming your proposed deck complies with the township’s zoning resolution.
- Prepare a site plan — Show all property lines, house location, and proposed deck including dimensions and setback distances. A formal survey is not required. You can use CAGIS online mapping at cagis.hamilton-co.org.
- Submit the site plan with the fee — There is no separate application form. Contact (513) 688-8400, ext. 3 for submission instructions.
- Wait for review — Township staff reviews for zoning compliance including setbacks and lot coverage.
- Receive your zoning certificate — You’ll need this when you apply for your building permit from Hamilton County.
Step 2: Apply for a Building Permit from Hamilton County
- Complete the building permit application — Available through ezTrak online portal or in person at 138 E. Court Street, 8th Floor.
- Prepare three copies of your building plans — Each must include your approved site plan. A digital PDF set is also recommended.
- Submit your application — In person, by mail, or online through ezTrak. A non-refundable plan processing fee is due at submission.
- Plan review — Residential deck reviews typically begin within 6 to 10 business days. Ohio law requires review within 30 days.
- Receive your permit — Pay the remaining permit fee. Post the permit on site before beginning work.
Filing an application does not give you permission to begin work. Permits expire if no work is started or no inspection is requested within six months of issuance.
What Your Plans Need to Include
Hamilton County’s deck checklist is detailed. Submitting complete plans the first time avoids correction notices. Include:
- Site plan with property lines, existing/proposed structures, distances to property lines, drainage direction, and utility easements
- Foundation plan with dimensions between all footings in both directions
- Floor plan showing door, window, and stair locations with dimensions
- Elevation views with finished grade, deck height, and railing height
- Footing details — minimum 30 inches below grade, with diameter, reinforcement, and minimum 2,500 PSI concrete
- Ledger board connection details — bolt size, spacing, embedment, flashing, joist hangers (not on brick veneer)
- Post-to-footing, post-to-beam, and beam-to-joist connection details
- Guardrail post spacing — maximum 8 feet on center; calculations required if wider
- All lumber specified as pressure-treated; all exposed fasteners as galvanized or stainless steel
- Maximum assumed soil bearing capacity of 2,000 PSF
- Drawing index with project address and owner/contractor/designer info on each sheet
Inspections
| Stage | What’s Reviewed | When to Schedule |
| Footing | Hole depth (min. 30 inches), diameter, undisturbed soil, reinforcement | Before pouring concrete |
| Framing | Ledger attachment, joist/beam sizes, post connections, hardware | After framing, before decking installed |
| Final | Completed deck — surface, guardrails, stairs, handrails, code compliance | After all work is complete |
Common Zoning Setbacks in Anderson Township
Setback distances vary by zoning district. Decks more than 30 inches above grade are generally treated as structures that must meet full setback requirements. Contact the Anderson Township Planning and Zoning Department at (513) 688-8400, ext. 3 for your specific requirements. If your deck doesn’t fit within required setbacks, you may apply for a variance through the Board of Zoning Appeals.
Tips for NE Hamilton County Homeowners
- Start with zoning, not building — The county will not accept your building permit application without an approved zoning certificate from the township.
- Verify your jurisdiction — If you have a Cincinnati mailing address but live in unincorporated Anderson Township, your permits go through the county — not the City of Cincinnati.
- Use CAGIS for your site plan — The free Hamilton County CAGIS online tool lets you pull a satellite-based map with parcel lines.
- Submit complete plans the first time — Missing footing dimensions, connection details, or guardrail spacing will trigger correction notices.
- Don’t skip the ledger detail — Missing or incomplete ledger board attachment details are one of the most common correction items.
- Budget for timeline — Between zoning (township) and building permit (county), plan for 2 to 4 weeks of review time before construction.
- Keep your permit active — Permits expire if no inspection is requested within six months. Schedule promptly at each stage.
