How does a Delaware permit differ from a Franklin County one?

In one important way: the paperwork is combined. The city issues Certificates of Building and Zoning Compliance, and says that in most circumstances only one permit is required for a project even when it has both building and zoning components. That is simpler than the Franklin County suburbs, where zoning and building approvals frequently arrive on separate tickets.

The Building Division sits inside the Department of Planning & Community Development at the City Hall Annex, 1 S. Sandusky Street, on 740-203-1600. It is a state-certified building department, and it describes its own remit as reviewing all new construction, alterations, improvements and replacements — a roof covering being a replacement. Applications are made through the city’s online portal, and the city describes creating a portal account as the fastest and easiest way to get a permit approved — for roof, HVAC, furnace and gas line work, it is a matter of completing the form there.

Does your roofer have to register in Delaware?

Not any more. The city announced that from 2026 contractors are no longer required to register with the City of Delaware in order to work there. They do still have to register with the city’s income tax division, which is a revenue requirement rather than a competence one.

That removes a check homeowners used to be able to lean on. Replace it with your own: ask for the certificate of liability insurance and the workers’ compensation certificate, confirm the company name on both matches the contract, and make sure the permit is applied for in the contractor’s name. A roofer who wants the homeowner to file the permit is asking you to carry the responsibility for their work.

What happens if you live downtown?

Delaware’s Downtown Historic District has its own gate. All alterations to property in the district require a Certificate of Appropriateness in addition to the usual building or zoning permit, and the Historic Preservation Commission reviews exterior modifications to buildings in the district, meeting on the fourth Wednesday of the month as needed.

The useful nuance is that roofs are frequently handled administratively rather than at a meeting, because a like-for-like replacement does not change the building’s appearance. That is a staff decision, not an assumption to make on your own: apply for the certificate before beginning work, and let the department tell you which route your job takes. A change of material or colour is the case most likely to go to the commission.

What does the permit cost in Delaware?

The city charges permit fees in accordance with its adopted fee schedule, published on the Planning & Community Development fees page, rather than quoting a single roofing figure in its guidance. The portal calculates what your application owes when you file it.

Two things are worth confirming when you do. First, that the fee you are shown is the whole fee — Ohio building departments add a Board of Building Standards charge to residential permits, and it should appear as its own line. Second, whether your parcel is inside the city limits at all: Delaware County has substantial unincorporated territory around the city, and a property outside the corporation line is a county matter rather than a city one. The portal and the department will confirm both in a phone call.

What does a roof replacement cost in Delaware?

The city publishes no housing-stock breakdown by roof pitch or storey count, and Delaware’s stock is genuinely split: nineteenth-century buildings around the downtown historic district at one end, and large recent subdivisions at the other. An average across those two would describe nothing. Measure your own roof.

The ranges in the roof cost estimator begin with a standard-grade shingle roof on a low slope over one storey, then multiply for pitch — 1.12 at 5/12 to 8/12, 1.30 at 9/12 and steeper — and for height, 1.08 over two storeys and 1.18 over three. A 25-square roof at a moderate pitch over a single storey plans at roughly $10,300 to $18,300. Inside the range: tear-off and disposal, underlayment and ice barrier, flashings, cleanup, and the permit and dump fees. Outside it: decking replacement, structural repair, ventilation upgrades and gutters.

On an older downtown house, assume the decking will need attention and get a per-sheet price before the tear-off. The shingle roof replacement guide covers the whole sequence, the metal roof replacement guide covers standing seam and metal shingles — a common question in historic districts — and our Columbus roofing permits guide explains how the process works south of the county line. If your address turns out to be in a designated area, our guide to the roof permit tax abatement explains what an abatement can and cannot do.
