A curb cut — the sloped section of curb where your driveway meets the street — sits in a regulatory gray zone. In most jurisdictions, a simple curb cut replacement or repair doesn't require a permit. But a new opening in the curb, or any work near an intersection, a bus stop, or a fire hydrant, almost always does. The distinction comes down to three factors: whether you're creating a new opening or maintaining an existing one, where on your lot the opening sits, and what local utilities or traffic concerns affect that location. Some cities handle curb cuts as a simple administrative approval; others require a formal permit with inspections. A few delegate it entirely to the street department rather than building inspection. This page walks you through the thresholds, the code sections that matter, and how to figure out what you actually need to file.
When curb cuts and driveway approaches require permits
The core distinction is whether you're creating a new opening or restoring an existing one. If your property already has a legal curb cut and driveway approach, and you're simply repairing, resurfacing, or replacing the existing apron, most jurisdictions treat it as maintenance and don't require a permit. If you're creating a new opening in the curb where none existed before — or if you're widening or relocating an existing one — you almost certainly need a permit. The reason: the curb is public infrastructure. Any new penetration or change in grade requires coordination with the street department, utility locating, and often traffic-impact review.
Proximity to an intersection is the second trigger. Most jurisdictions prohibit curb cuts within a certain distance of an intersection corner, measured along the street edge. That distance varies widely — 15 feet, 20 feet, 25 feet, even 35 feet in some places — and is usually set in the local zoning or street design ordinance, not the building code. The rule exists to preserve sight lines and pedestrian safety. If your lot corner is close to an intersection, your curb-cut application may be rejected outright, or it may require a variance or special-permit review. This is the single most common reason curb-cut applications fail.
Distance from utilities and public services also matters. A curb cut too close to a fire hydrant, water valve, storm drain, or electrical service will trigger either a denial or a requirement to relocate the hydrant or valve at your cost — which can run $2,000–$8,000 or more. Before you file, ask the building department whether the street department has already done a utility conflict review. Some jurisdictions do this automatically; others wait until you file and then order a locating. Either way, you need to know about conflicts early.
The code section that governs curb cuts varies by jurisdiction, but it's almost never the building code itself. In most cities, curb cuts fall under the street design standards or zoning ordinance, not the International Building Code. A few jurisdictions include curb-cut standards in their local building code amendments — typically in the site-development or grading sections. Some defer to the state Department of Transportation or state manual for uniform traffic-control devices. The permitting authority is often the street department or public works division, not the building inspection division, though building inspection may co-review for accessibility compliance under the ADA.
Accessibility is a secondary but crucial layer. The ADA requires that curb cuts meet specific slope, width, and landing requirements. Those standards are in the ADA Accessibility Guidelines and the 2015 International Building Code's Appendix D. A new curb cut must slope at no more than 1:12 (roughly 8%), have a minimum width of 4 feet (5 feet is safer and increasingly required), and have a level landing at top and bottom if the approach is longer than 15 feet. If your design doesn't meet these, your application will be rejected. Many homeowners don't realize that a DIY or contractor-built curb cut that looks fine visually may fail inspection because the slope is too steep or the width is off by 6 inches.
Scope drawings and specifications are where many applications fail. The permitting authority needs to see the new curb-cut location marked on a site plan (with dimensions from property lines, not just 'over there'), the proposed width, the slope grade, the surface material, and any drainage details. You also need to show that the cut won't conflict with utilities. A rough sketch often isn't enough — most jurisdictions want a dimensioned plan, usually prepared by a licensed engineer or surveyor if the cut is complex or near an intersection. The application form itself varies: some cities have a dedicated curb-cut permit form; others lump it into a general driveway or site-work permit. Check with your local building or street department before you file to confirm what they want to see.
How curb-cut permit requirements vary by state and region
Curb-cut permitting authority and process differ sharply by region, sometimes even between neighboring municipalities. In many Midwestern and Southern states, curb cuts fall under the street department or public works division, not building inspection. You file with the street department, not the building permit counter. In some Northeastern states and California, the building department or planning department handles it. A few states — including Florida and parts of Texas — have state-level curb-cut standards tied to drainage and flood-control rules because of flat terrain and stormwater concerns. Before you assume your local building department is the right office, call and ask. The difference can add 2–4 weeks to your timeline if you file with the wrong office.
Intersection setback rules vary dramatically. New York City requires 25 feet from an intersection corner. Many California cities use 20 feet. Some suburbs enforce a gentler 15 feet. A few rural jurisdictions have no specific setback rule at all, relying instead on engineering judgment. If your lot is on a corner or within a few feet of an intersection, the local setback rule may make a new curb cut impossible without a variance. Check the zoning ordinance or call the building or planning department to confirm the setback before you hire a contractor. A variance adds 8–16 weeks and costs $300–$1,000.
Drainage requirements are stricter in wet climates and flood-prone areas. Parts of the Pacific Northwest, the Upper Midwest, and the Southeast require that curb-cut design include stormwater management — typically a grade or swale directing runoff away from the house and into a storm drain or dispersion area. In some Florida jurisdictions, a new curb cut requires proof that it won't increase flooding or runoff to adjacent properties. If your area has stringent stormwater code, a simple curb-cut permit may require a drainage plan prepared by a licensed engineer, adding $500–$2,000 to design costs. Check with your local public works or building department early to confirm whether drainage details are required.
ADA compliance enforcement varies. In most jurisdictions, new curb cuts must meet ADA standards or the application is rejected. But the rigor of inspection and enforcement differs. Some building departments have ADA specialists who review every curb-cut plan detail. Others do a visual inspection at the end. If you're in a jurisdiction that has faced ADA litigation or has a dedicated accessibility officer, expect tight scrutiny of slope and width. If you're in a rural or small-town jurisdiction, the oversight may be lighter — but that doesn't mean you should skip compliance. ADA violations can trigger complaints, forced remediation, and legal liability.
Common scenarios
Replacing an existing driveway apron in place (same location, same width)
If your driveway approach already has a legal curb cut and you're simply replacing the concrete apron because it's cracked or settling, most jurisdictions treat this as maintenance and exempt it from permitting. The curb cut itself isn't changing — you're just resurfacing. However, check with your local building or street department first, especially if the apron work requires excavation near the curb, because some jurisdictions require a small administrative notice even for in-kind replacement. If you widen the apron or change its grade during replacement, you'll likely need a permit. And if you're also regrading the driveway or adding drainage, a permit becomes necessary. The safe move: call the building department and describe the work. If it's purely cosmetic replacement, you'll get a no-permit answer in one call. If there's any doubt, get it in writing before you start.
Creating a new curb cut on a lot that has never had one
A new opening in the curb requires a permit in virtually every jurisdiction. You're changing public infrastructure — the curb itself — so you need approval from the street department or public works. The permit process typically includes a site plan showing the new cut location (with dimensions from the nearest property corner and the nearest intersection), a proposed curb-cut width and slope, and confirmation from utility locating (call 811 or your state's utility-locating service) that there are no conflicts. If your property is on a corner or within 15–35 feet of an intersection (the distance varies), you may face a setback violation that requires a variance, or the application may simply be denied. Filing takes 1–4 weeks depending on whether the department staff approves it over-the-counter or sends it to a design review board. Cost is typically $75–$250. Expect a final inspection once the curb cut is cut and the driveway approach is in.
Widening an existing curb cut by 2 feet and adding a drainage swale
Widening the curb cut and modifying the grade to add drainage both trigger permitting. The widening changes the public curb and the grade, and the swale involves site drainage, which is regulated under stormwater code in most jurisdictions. You'll need a site plan showing the existing curb cut, the proposed new width and location, the drainage swale design, and confirmation that utilities are clear. If you live in a climate with wet winters or in an area with stormwater regulations, the drainage portion may require a licensed engineer to prepare a stormwater plan — add $800–$2,000 and 2–3 weeks to the timeline. File with the street department and/or public works, not just building inspection. Total time is 3–6 weeks. Cost is typically $150–$400 for the permit, plus engineering fees if required. You'll get inspections after the curb is cut and after the drainage is in.
Adding a second curb cut 8 feet away from an existing one to create two driveways
Whether this is allowed depends on local lot-division rules, access rules, and whether the property is on a corner. Some jurisdictions allow multiple curb cuts on a single-family residential lot if they're spaced at least 20–30 feet apart and don't violate other rules. Others have a one-curb-cut-per-frontage rule and won't approve a second. If your lot is a corner lot, the second cut may trigger intersection setback issues. And if the property is in a historic district or has conservation easements, there may be additional review. You'll need to file a permit application with a site plan, and the street department or planning division will review it against the applicable ordinance. If the second cut is denied on policy grounds, you could pursue a variance, but that's expensive and not guaranteed. The outcome here really does depend on your specific location and the lot configuration. Before you design around a second driveway, call the building or street department and ask directly: is a second curb cut allowed on this lot? Get the answer in writing.
Replacing a curb cut that's near a fire hydrant 4 feet away
The fire department typically requires at least 3 feet of clear space on either side of a fire hydrant for hose deployment. If your curb cut is closer than that, the application may be rejected unless you agree to relocate the hydrant. The cost of relocating a fire hydrant is usually borne by the property owner and can range from $2,000 to $8,000 or more. If you're simply replacing an existing curb cut in the same location, the fire department may grandfather it and allow the replacement to proceed without moving the hydrant — but you need to confirm this with the street department before you file. If you're creating a new curb cut or widening an existing one near a hydrant, expect a denial or a relocation requirement. Call the street department and the fire department before you commit to a design. Permit processing for this scenario typically stalls pending hydrant-relocation approval, so timeline is 4–8 weeks if a move is required.
What to file and where
| Document | What it is | Where to get it |
|---|---|---|
| Site plan or survey | A dimensioned drawing showing the lot boundaries, the location of the proposed curb cut (with distance from nearest property corner and nearest intersection), the width and slope of the new curb cut, existing utilities, and any adjacent structures or driveways. Scale is typically 1 inch = 20 feet or 1 inch = 40 feet. | You can sketch this yourself if the cut is simple and the lot is small, but many jurisdictions prefer a licensed surveyor or engineer's plan. For corner-lot cuts or cuts near utilities, a professional plan is safer and may be required. Cost is $300–$800 for a simple survey. |
| Curb cut / driveway approach permit application | The official application form for the permit, which varies by jurisdiction. It asks for owner name, address, scope of work, estimated cost, and often requires a signature indicating understanding of the rules. | The street department, public works division, or building department — depending on which office handles curb cuts in your city. Many departments post the form on their website. If not, call and ask them to email it or bring a blank when you visit in person. |
| Utility locate request (811 call) | A notification to the state or regional utility-locating service (usually called 811 or the Dig Safe system) to mark the location of underground gas, electric, water, sewer, and telecom lines. Required in most jurisdictions before you file a permit or start any excavation. | Call 811 or visit call811.com and enter your address. Locating is free and usually takes 2–5 business days. Keep the locate ticket number and dates; provide them with your permit application. |
| Driveway design or specifications (if required) | Details on surface material (concrete, asphalt, pavers), thickness, base preparation, and slope. Many jurisdictions want the driveway designed to ADA slope standards (1:12 or less) even though the standard only strictly applies to curb cuts. If your jurisdiction requires a stormwater plan (drainage swale, retention details), that goes here too. | Your contractor or engineer should provide this as part of their bid package. If you're hiring someone, make sure the plan includes slope and width details before you file the permit. |
| Variance or exception request (if required) | If the proposed curb cut violates setback, spacing, or other rules, you may need to file a formal variance request or ask for a code exception. This requires a separate application, a public hearing in many jurisdictions, and additional fees. | The building or planning department. File this at the same time as the curb-cut permit if you know a variance is needed. Processing time is typically 8–12 weeks. |
Who can pull: The property owner can file the permit application directly in most jurisdictions. A licensed contractor can file on your behalf if they have a signed authorization. The street department or building department will not file for you; you must submit the application and drawings. Some departments allow online filing; others require in-person submission or mail. Check your local department's website to confirm their filing method and hours. If the department is slow or you want to avoid multiple trips, hiring a local permit expediter or engineer who knows the department can save time and reduce rejection risk, though it will cost $200–$500 in expediter fees.
Why curb-cut permit applications get rejected (and how to fix them)
- Application incomplete — missing site plan or utility-locate information
The department needs a dimensioned site plan showing lot boundaries, the proposed curb-cut location, distance from intersection, and a copy of the 811 utility-locate ticket or results. Don't submit without these. If you file online and the form has required fields, fill every one or the system will bounce it automatically. - Proposed curb cut violates intersection setback rule
Check the local zoning or street design ordinance for setback distance (typically 15–35 feet from an intersection). If your cut falls inside that zone, the application will be denied unless you file for a variance or the department has discretion to grant an exception. Some jurisdictions do grant exceptions for lots with no other feasible access, but don't count on it. The safe move is to measure the distance before you file and confirm with the planning department that the location is feasible. - Utility conflict — proposed cut is too close to a fire hydrant, water valve, or other utility
The 811 locate will show most utilities. If the locate report shows a conflict, you'll need to either move the proposed cut location or agree to relocate the utility. Hydrant relocation costs $2,000–$8,000 and requires fire department approval. Discuss this with the street department before you file and get an estimate if relocation is necessary. - Curb-cut design doesn't meet ADA slope or width standards
New curb cuts must slope at no more than 1:12 (about 8.3%). If your proposed slope is steeper, you'll need to modify the design or adjust grades. Minimum width is 4 feet (5 feet is recommended). Check the ADA Accessibility Guidelines or ask the building department for the exact slope requirement in your jurisdiction. Have your engineer or contractor adjust the design to comply before resubmitting. - Application was filed with the wrong department
Curb cuts are sometimes handled by street/public works and sometimes by building inspection. Call ahead and confirm which office handles curb-cut permits in your city. If you filed with the wrong office, the application will be bounced and you'll need to resubmit to the correct office, adding 1–2 weeks to the timeline. - Site plan lacks required dimensions or detail
The plan needs to show the proposed cut location with dimensions from the nearest property corner and the nearest intersection (or both, depending on the department). It also needs to show the proposed width, depth, and slope of the cut, and confirm drainage flow. A rough sketch often won't pass — submit a dimensioned engineer's plan or a surveyor's plan if the department has rejected a hand-drawn plan before.
Curb-cut permit costs
Curb-cut permit fees are usually low, but design and relocation costs can add up. The permit itself typically runs $50–$250, often as a flat fee rather than a percentage of project valuation. If the cut is simple and in a clear location, you may be able to file with a sketch and get approval in 1–2 weeks. If the cut is near an intersection, requires a variance, or conflicts with utilities, expect additional costs and timeline delays. Professional design (engineer or surveyor) adds $300–$2,000 depending on complexity. Utility relocation (if required) can add $2,000–$8,000 or more.
| Line item | Amount | Notes |
|---|---|---|
| Curb-cut permit (base) | $50–$250 | Flat fee in most jurisdictions. Faster departments may not charge a separate fee if curb-cut work is bundled into a driveway permit. |
| Site plan / survey | $0–$2,000 | Free if you sketch it yourself; $300–$800 for a surveyor's plan; $500–$2,000 for an engineer's plan with drainage details. |
| Variance filing (if needed) | $300–$1,000 | Required if the cut violates setback rules or local ordinance. Includes application fee and often a public-hearing cost. |
| Utility relocation (if needed) | $2,000–$8,000+ | Fire hydrant, water valve, or other utility in conflict. Cost varies by utility type and relocation distance. Usually borne by property owner. |
| Stormwater / drainage plan (if required) | $500–$2,000 | Engineer design for swale or grading. Required in some jurisdictions; optional in others. Check with local public works. |
| Permit expediter (if hired) | $200–$500 | Optional service to handle application filing and coordination. Saves time and reduces rejection risk, especially for complex cases. |
Common questions
Do I need a permit to just repaint or seal-coat an existing driveway apron?
No. Cosmetic work on an existing apron — painting, seal-coating, or minor patching — doesn't require a permit. If you're replacing significant sections of concrete or asphalt in the apron because it's failing, that's usually still exempt as maintenance. But if you widen the apron, change its grade, or add drainage, a permit becomes necessary. When in doubt, call the street department and describe the work. They'll tell you in 5 minutes whether a permit is needed.
My lot is on a corner. Can I have a curb cut on both streets?
Usually no. Most zoning ordinances allow only one curb cut per street frontage, and corner lots are often limited to one cut total to avoid over-development of the corner and to preserve sight lines. You may be allowed a cut on the side street if the front-street cut is unusable due to topography or other constraints, but this requires a variance or planning director approval. Check your local zoning ordinance or call the planning department before you invest in a design for two cuts.
How close can a curb cut be to a fire hydrant?
The fire department generally requires at least 3 feet of clear curb on either side of a hydrant for hose deployment. If your cut is closer than that, the hydrant will need to be relocated at your cost (typically $2,000–$8,000) or the permit will be denied. If you're replacing an existing cut that's close to a hydrant, it may be grandfathered and allowed to stay, but confirm this with the street department before you file.
What's the ADA slope requirement for a curb cut, and why does it matter?
The ADA requires a maximum slope of 1:12, which equals about 8.3% grade. If your curb cut is steeper than that, it's difficult or impossible for someone in a wheelchair to navigate, and the permit will be rejected. Slopes are measured as rise over run — a 1:12 slope means 1 inch of rise for every 12 inches of horizontal distance. If your lot slopes steeply toward the street, achieving 1:12 may require grading or fill, adding cost and time. Check the existing lot slope and discuss feasibility with your engineer or contractor before you commit to a design.
How long does a curb-cut permit take?
For a straightforward cut in a clear location with no conflicts, 1–2 weeks is typical for over-the-counter approval. If the application is incomplete or needs review by multiple departments (street, fire, utilities), add 2–4 weeks. If the cut violates setback or other rules and requires a variance, add 8–16 weeks for the variance process. If utilities are in conflict and relocation is necessary, add 4–8 weeks for relocation approval and scheduling. Plan for 3–4 weeks as a realistic baseline; longer if complications arise.
Can I file the permit myself, or do I need a contractor?
You can file it yourself in almost all jurisdictions. You don't need a licensed contractor to apply for a curb-cut permit — it's public infrastructure, not building work. But you do need to prepare or hire someone to prepare a dimensioned site plan, call 811 for utility locating, and submit the application to the correct department (street, public works, or building, depending on your city). If you're unsure about any part of the process, hiring a local permit expediter ($200–$500) to handle the filing can save time and reduce rejection risk.
What happens if I create a curb cut without a permit?
The city will likely order you to stop work and restore the curb. You'll be fined (typically $100–$500 per day of non-compliance) and required to file a permit retroactively, which can be harder and more expensive than doing it right upfront. If the work damaged utilities or failed to meet code, you'll be liable for repairs and safety hazards. In rare cases, the city will undo the work at your expense. Most importantly, an unpermitted curb cut may not be approved retroactively if it violates code or conflicts with utilities, leaving you with an illegal cut that you have to pay to fix.
Do I need a stormwater plan if I'm adding a curb cut?
It depends on your local stormwater code and the site conditions. If you live in a wet climate or a flood-prone area, or if your jurisdiction has strict stormwater rules, yes — you'll likely need a grading and drainage plan. If you live in a drier area with loose stormwater code, it may not be required. Check with your local public works or building department when you call about the permit. If drainage is required, have your engineer or contractor prepare a simple grading plan showing how runoff will flow from the driveway away from the house. Cost is typically $500–$2,000.
My contractor wants to just 'cut the curb and see what happens.' Should I let them?
Absolutely not. An unpermitted curb cut can be fined, ordered to be restored, or denied retroactive approval if it violates code or conflicts with utilities. Your contractor may be trying to save time, but you're the one liable. Insist on filing the permit before work starts. A legitimate contractor will expect this and will not pressure you to skip it. If your contractor is pushing to cut the curb first and ask forgiveness later, consider hiring someone else.
Can I appeal a curb-cut permit denial?
If the denial is based on policy (e.g., intersection setback violation), you can file a variance or ask the planning director for discretionary approval, which typically involves a hearing and costs $300–$1,000. If the denial is based on incomplete application, you can fix the application and resubmit. If the denial is based on a code conflict (like an ADA slope violation), you'll need to modify the design to meet code and resubmit. Appeals are possible but not guaranteed to succeed, especially for policy-based denials. Before you appeal, ask the department what would be needed to make the application approvable, and weigh that cost and timeline against alternatives (like a variance or redesign).
Ready to file your curb-cut permit?
Start by calling your local street department, public works division, or building department and asking one question: Do I need a permit for a [describe your work]? Most departments will answer in under 5 minutes. If the answer is yes, ask for the application form, any local design standards, and confirmation of the filing process (online, in-person, or mail). If you need a site plan, call a local surveyor or engineer — their intake call is free, and they can tell you the cost and timeline. If your project involves a new opening, proximity to an intersection, or utility concerns, don't skip the permit process. It's faster and cheaper to do it right upfront than to fix violations or removals after the fact.
