In Columbus, expanding a driveway or parking pad requires zoning clearance. A driveway extension permit for right-of-way work may also apply when construction reaches the public approach, sidewalk, or curb.
We identify the proposed footprint and permit responsibility before setting the pour date. Keeping the entire extension on private property still leaves zoning requirements to address.
New or expanded driveways and parking pads require zoning clearance under city rules. Repaving an approved area without expanding it does not require that clearance.
The existing approved footprint matters when defining an expansion. Adding parking space beside the current driveway changes that footprint, even when the street entrance stays untouched.
Zoning, building, and right-of-way requirements are separate. One approval does not cover every part of the job. We address these requirements through our concrete permit planning before construction.
An extension contained on private property starts with the zoning requirements for that parcel. Work that reaches the public driveway approach, sidewalk, curb, or street opening also requires right-of-way approval.
For example, adding width beside a garage can leave the public approach unchanged. Widening the entrance at the street changes another part of the project. Demolition limits therefore matter alongside the new concrete outline.
Franklin County building and zoning arrangements vary by township and municipality. The parcel’s jurisdiction determines which office handles the applicable approval.
Have the contractor confirm permit scope and responsibility with the local office for the actual address and design. This review belongs before work begins, especially when the extension crosses into public right-of-way.

Every estimate breaks out slab thickness, PSI, reinforcement, sub-base, and finish as separate line items, so you can compare it against any other proposal on equal terms.
Public Service’s 905 right-of-way permit covers installation, removal, or repair of public sidewalks, driveway approaches, and curbing. The category includes a stated exception for work covered by public-improvement plans.
Removal alone can require this permit. A concrete extension that also removes part of the public approach needs that work included in the permit review.
The written scope should identify who obtains the permit and coordinates the required inspections. Those responsibilities affect scheduling before a concrete delivery can be arranged.
Base materials and forms need approval before concrete placement for covered city right-of-way work. Pouring without authorization can require removal and replacement at the permittee’s expense.
Published driveway-width guidance applies to specific configurations and zoning districts. A dimension given for one garage layout should not become the assumed width for every extension.
We use written specifications to establish the proposed work before placement. The approved layout and any required inspection must align with those specifications.
Ohio’s excavation notification law generally requires notice at least two working days before excavation, excluding the notification day. Notice must also fall no more than sixteen calendar days before excavation, subject to statutory exceptions.
OUPS utility locating notification through OHIO811 is free. Private locating and contractor coordination are separate services; any related charges should be identified accurately in the estimate.
We include utility notification in our planning. If utility conflicts affect the extension, the contractor and utility professionals need to resolve them before excavation proceeds. This notice window is separate from the time needed for permit review or approval.
Extension size, demolition, materials, finish, permits, inspections, utility locating, soil, drainage, and crew scheduling affect cost and timing. For our concrete driveway installation, we provide written, itemized estimates that identify the work before pouring.
The estimate should identify the removal area and existing material so competing quotes cover the same scope.
Some Franklin County properties have clay-heavy or poorly draining soils. Clay soil movement and weakened support during thaw make site-specific preparation important. Sub-base depth should reflect actual ground conditions and the proposed driveway use.
We use air-entrained exterior concrete for freeze-thaw exposure. Its small air voids help relieve pressure when water freezes within concrete. Drainage slope helps limit standing water, while finishing and curing also affect resistance to surface scaling.
Our specify-then-pour process puts these variables in writing. We recommend separate estimate items for the following specifications and responsibilities.
The schedule must allow for approvals, utility notification, excavation, base preparation, required inspections, placement, and curing. Crew availability and site conditions affect when these stages can happen.
The written curing timeline should also explain when vehicle use can resume. Sealing timing follows the selected product and curing method, without relying on a universal waiting period.
Changing the paving material while keeping the approved footprint fits the city’s distinction for repaving without expansion. The key is that the existing area was approved. Removal or replacement involving the public approach, sidewalk, or curb still requires separate right-of-way approval. The proposal should distinguish material replacement from any added parking area.
No. A widened parking area beside the house can need zoning clearance while leaving the public approach untouched. If that same project also changes the public approach, it also needs the 905 right-of-way permit.
A homeowner who obtains the permit can be responsible for corrections associated with covered right-of-way work. Hiring a contractor does not automatically remove that permit responsibility. Before applying, settle who will coordinate inspections and handle required corrections. Put those responsibilities in the written scope so they are addressed before concrete placement.
That depends on the parcel’s zoning requirements and the proposed layout. City driveway-width guidance is context-specific, and district restrictions can affect the design. The existing driveway’s approval does not authorize added width toward the side boundary. Include the proposed extension’s location in zoning review before finalizing its dimensions or demolition limits.
