Curb Cut Permit for a Driveway: What the City Controls

A new concrete driveway apron and curb cut being poured at the street in front of a house

Usually yes. A new or wider curb cut sits in the public right-of-way, so most cities and counties require a Public Works or right-of-way permit, separate from a building permit.

Your contractor says the new concrete is “just flatwork.” You widen the driveway for a third car, or rip out a cracked apron so the garage looks finished.

Then Public Works shows up — or a sidewalk inspector — because the piece that meets the street is not private property. It sits in the public right-of-way (ROW).

This guide covers driveway permits, curb cuts, aprons, and sidewalk crossings: what is public vs private, when cities and counties usually require permission, how Public Works / transportation permits differ from building permits, a packet checklist, and the fail patterns that stall pours. Rules are local. Fees and width caps below are city examples, not national law. PermitCove is an independent homeowner guide — not a government agency and not your engineer. Confirm with your AHJ.

Public ROW vs private driveway (the line that matters)

Driveway apron (approach) — the flared piece connecting the street to your drive, often including the sidewalk crossing — typically in the ROW.

Property line — the legal split.

Private driveway — behind the line, on your lot, leading to parking or a garage.

Portland’s Bureau of Transportation publishes this split clearly: the apron and sidewalk portion are in the public right-of-way; the driveway behind the property line is on private property. Detroit’s Department of Public Works describes ROW as streets, alleys, sidewalks, curbs, and the berm/green area between curb and sidewalk. Work in that zone is not “your concrete” in the legal sense — the city or county controls how it may be altered.

That is why a building clerk can say “we don’t permit flatwork” while a Public Works counter still needs a curb-cut or residential-access permit for the same project.

For the building-permit side of a Detroit project, see our Detroit building permits guide.

When homeowners typically need a curb-cut / ROW permit

Six typical curb-cut and right-of-way permit triggers including new cut, widen, replace apron, sidewalk crossing, second driveway, and wrong office

Across published .gov pages, these scopes keep showing up as triggers:

New curb cut — opening a driveway through an existing curb/sidewalk (Seattle: SDOT oversees curb cuts because curbs are in the City ROW; SDCI notes the permit may be stand-alone or part of a building permit).
Widen, relocate, or change throat/flare — Portland states that installing or changing a driveway accessed from City ROW always requires a permit.
Replace or reconstruct the apron / drive approach in the ROW (Detroit lists curb cut and drive-approach remove/replace among ROW permit types; New Orleans requires a driveway or curb-cut permit to install, replace, or repair a driveway that connects to a public street).

Sidewalk, curb, and gutter work tied to the crossing — disturbed sidewalks and curbs usually must be restored in kind to city/county standards (Baltimore County and Anne Arundel County publish that restore-in-kind rule).
Second entrance or circular / U-shaped drive — often limited or discretionary (Baltimore County typically allows one driveway; circular drives need minimum frontage; Town of Hempstead, NY publishes frontage and spacing rules for connected curb cuts).

Portland goes further: curb cuts are authorized only to reach legal vehicle parking or loading — not for trash rooms or similar non-parking uses. If your goal is “cut the curb so we can pull onto the lawn,” expect a hard no or a redesign.

Start with the 10-minute AHJ check, and ask two counters if needed: Building and Public Works / Transportation / Highways.

Public Works / traffic vs building permit

	ROW / Public Works / Transportation	Building / Development Services
Focus	Curb cut, apron, sidewalk crossing, berm, drainage in the ROW, sight distance, restore-in-kind	Private paving, garage, parking pad structure, zoning setbacks, life safety
Typical name	Curb cut, residential access, driveway apron, street use, minor improvement, ROW permit	Building, zoning, grading, or “private property” paving permit
Who inspects	Public Works / DOT / Highways inspectors	Building inspectors
Can one replace the other?	No	No

Portland’s pattern is a useful mental model: ROW driveway work may need a Minor Improvement or Public Works permit; private-property driveway construction needs a different permit from Portland Permitting & Development; fees and inspections are separate even when you apply through one portal. Seattle’s curb-cut page is explicit that the curb-cut permit does not approve parking layout or landscaping in the ROW — those are other reviews.

City street vs county road vs state highway: Baltimore County’s residential-access page states that access to a state road (route number) needs a Maryland State Highway Administration permit — the County does not issue that access. Portland’s driveway page says the same idea for ODOT or county facilities. Call the agency that owns the road you are cutting into.

For the building-side process and paperwork habits, use how to apply for a building permit and clarify who pulls the permit when a concrete crew and a general contractor are both on site.

HOA angle (brief)

Architectural Review may love your paver pattern and still have zero authority to authorize cutting a public curb. HOA approval and public permits are separate tracks — you often need both. Details: HOA approval vs city building permit. Historic districts and parks agencies can add a third gate (New Orleans lists Historic District / Vieux Carré / Parks & Parkways reviews when they apply).

Packet checklist (copy / adapt)

Composite from New Orleans DPW, Baltimore County residential access, Portland PBOT, and Town of Hempstead Highways pages:

Proof of ownership or owner authorization letter
Dimensioned site plan — property lines, house (front called out), existing and proposed driveway/curb cut, road name, distances to side lot lines and nearest intersection / corner
Width callouts at curb line and at property line (cities publish different caps; Hempstead lists residential max widths at the curb; Baltimore County caps access width at the property line in its published rules — use your handout)
Photos of existing curb, sidewalk, and apron (real site photos; some cities reject Google Street View screenshots)
Obstructions — hydrants, poles, trees, meters, catch basins, mailboxes, EV chargers, lights
Drainage / culvert notes if you have an open roadside ditch (Lake County, Florida’s apron form and Baltimore County’s open-section standards both emphasize drainage continuity)
Utility form / dig ticket if required
Extra approvals — HOA letter, historic, parks, state DOT if you access a state route
Applicant name matching who will schedule inspections

Keep the same site plan version for every office. Version drift is how aprons get poured wider than the stamped sheet.

Common fail patterns

Private pour first: beautiful driveway on the lot; curb still untouched; then ROW permit denied or redesigned.
“Same apron, no permit” assumption: many cities still require a permit to reconstruct or repair the public approach (New Orleans explicitly includes replace/repair).
Wrong jurisdiction: city crew cannot approve a county- or state-road cut.
Second driveway on a short lot: frontage and spacing rules reject the sketch.
Parking on the apron / sidewalk: public ROW is for crossing, not storing cars (Baltimore County and Chicago CDOT driveway rules emphasize this).
HOA-only start: association stamp, no Public Works permit, then st
op-work or tear-out risk.
Abandoned old curb depression left open after relocating a drive — counties often require full-height curb restoration.
Ignoring ADA sidewalk path across the apron where a walk exists (Lake County’s published apron standards call out a compliant path and cross-slope limits — ask your AHJ for their detail).

If a notice is already posted, stop and stabilize — then use stop-work first 48 hours. For work already poured without approval, see after-the-fact paths and expect a ROW restoration conversation as well. Before you buy a house with a mystery widened drive, check permit history.

Who is allowed to pull the curb-cut permit

Don't assume you can buy it yourself just because you own the house. Some cities only sell right-of-way permits to contractors who are bonded or registered with them. Houston is a clear example. For its driveway and sidewalk permit, "only a bonded contractor will be able to purchase this permit," though the homeowner may buy it when no curb cut is involved (Houston Permitting Center (PDF)). Our Houston permits guide covers the rest of the city's rules.

Before you sign with a concrete crew, ask the Public Works counter two questions: who can pull the permit, and does the contractor have to be registered, bonded, or insured with the city? A crew that can't pull the permit is a crew that may be tempted to skip it.

And before anyone breaks out the old apron, contact 811. It's free, and you should reach out a few business days before digging so buried utilities get marked (811).

Inspections and close-out

Expect separate eyes on the public and private pieces when both permits exist. Forms and forms: keep the approved plan on site, match joint locations and concrete thickness to the standard detail, and do not bury the curb until the inspector signs off. Prep habits transfer from building work — see inspection prep.

Corner lots add sight-triangle and setback pressure similar to fence rules; if your driveway sits near an intersection, open the fence / corner-lot guide for the visibility mindset, then ask Public Works for driveway-specific corner distances.

Who maintains the apron after it's poured

Here's the part people don't expect: even though the apron sits on public land, some cities make the owner next to it responsible for keeping it in shape. Lakewood, Ohio's code says the abutting owner is "primarily responsible for the repair and maintenance" of the sidewalk, driveway apron, and tree lawn. If the city finds a hazard, it can order the owner to fix it, with at least 30 days to do the work, and if a sidewalk still isn't repaired, the city can do it and assess the cost to the owner (Lakewood Codified Ordinances 903.10).

Not every city works this way, so look up your sidewalk ordinance or ask Public Works. If the upkeep is on you, an apron poured to the city's standard detail now is cheaper than a repair order later.

FAQ

Do I need a permit to replace a cracked driveway apron?

Often yes when the apron sits in the public ROW. New Orleans requires a driveway or curb-cut permit to install, replace, or repair a driveway connecting to a public street. Ask Public Works, not only the building counter.

The building department said flatwork is exempt. Am I done?

Not if you are altering curb, sidewalk, or apron in the ROW. That is usually a different permit family.

Can I widen only the private driveway and leave the curb alone?

Maybe — if the existing curb cut already matches the new width and your AHJ allows private paving without a building permit. The moment the throat, flare, or sidewalk crossing changes, you are back in ROW territory. Portland treats changing a driveway as a permit trigger.

How wide can my curb cut be?

Local. Town of Hempstead publishes residential maximums at the curb line; Baltimore County publishes a maximum access width at the property line; Lake County, Florida publishes property-line width and flare rules on its apron form. Use the sheet for your road owner — do not copy a neighboring town’s number.

What about a circular or second driveway?

Many counties limit you to one entrance unless you meet frontage and discretionary approval. Budget for a “no” or a redesign.

Does HOA approval replace the city curb-cut permit?

No. Private covenants do not authorize work in the public ROW. See HOA vs city.

Who do I call if my street is a state highway?

The state DOT / highway administration for access, plus any local permits for work they do not cover. Baltimore County’s page states this split plainly for Maryland state roads.

How far ahead should I apply, and what does it cost?

Apply early, and expect a local fee. St. Louis asks for driveway permit applications at least one week before the date needed, or two weeks for bigger jobs. It lists residential fees of $50 for a new driveway and $25 to reconstruct one, and you supply your own barricades, with reflective tape and flashers after dark (City of St. Louis). Your city's numbers will be different.

There's a ditch in front of my house, not a curb. Do I still need a permit?

Usually yes. In unincorporated Harris County, Texas, if the ditch lies in the county right-of-way, any driveway built there needs a permit, and the county asks for a residential application and a detailed site plan (Harris County Office of the County Engineer). Expect questions about the culvert and drainage, like the ones in the packet checklist above.

Bottom line

The driveway project that “doesn’t need a building permit” can still need a curb-cut / apron / ROW permit because the apron and sidewalk live on the public side of the property line. Identify who owns the road, draw the public vs private split on your site plan, apply to Public Works (and Building when private work needs it), and pour only what the stamped sheet shows. That sequence beats tearing out fresh concrete.

Next: run do I need a permit?, then how to apply, and keep the AHJ checklist open when you call both counters.
