Got a Sidewalk Repair Notice? Permits, Deadlines and Costs

Short answer: in many U.S. cities the owner next to the sidewalk must repair it, with a permit from the street or transportation department, by a short deadline: 30 days in Oakland and San Francisco, 60 in Portland, 75 in New York City. Miss it and the city can do the work and bill you.

It usually arrives as an ordinary-looking envelope from the city, or as a few spray-painted dots on the concrete out front. Either way the message is the same: the sidewalk next to your house has a trip hazard, you are expected to fix it, and there is a deadline. Most homeowners never thought of that strip of concrete as theirs. In a lot of U.S. cities, for repair purposes, it is.

This guide walks through what a sidewalk repair notice means, who is actually responsible, when the repair needs a permit (and from which office), how long you have, what the city charges if it does the work for you, what changes when a street tree caused the damage, and where cost-share programs can lower the bill. It is based on official pages from Portland, San Francisco, New York City, Oakland, San José, Seattle, Chicago, Los Angeles and Denver. Rules really do differ from city to city, so use these as examples of what to ask your own public works or transportation department.

The short answer

• In many cities the adjacent property owner must repair the sidewalk. Portland's city charter puts sidewalk maintenance on the adjacent owner (Portland Bureau of Transportation). San Francisco cites California Streets and Highways Code section 5610 and its own Public Works Code (San Francisco Public Works). New York City's Administrative Code section 19-152 makes owners responsible for installing, repairing and maintaining the sidewalk next to their property (NYC DOT).
• Not everywhere. Denver voters moved sidewalk building and repair to the city in 2022, paid for by an annual sidewalk fee on every property (Denver DOTI).
• The repair usually needs a permit from the street department, not the building department. Portland says flatly that "sidewalk repair requires a permit" (Portland Bureau of Transportation), and San Francisco requires a Sidewalk Repair Permit "for any sidewalk repair work" (San Francisco Public Works). Oakland only requires one for repairs larger than 25 square feet (City of Oakland).
• Deadlines are short and they vary. 30 days in Oakland and San Francisco, 60 days in Portland, 75 days in New York City. Miss them and the city can do the work and bill you.
• Tree roots change the rules in some cities. New York City no longer charges owners of one-, two- and three-family homes for sidewalk damage caused by City trees (NYC DOT). Oakland now holds the adjacent owner responsible even when the tree was once considered "official" (City of Oakland).

If you are planning work in front of the house anyway, such as a new driveway apron, read our guide to driveway curb cut and right-of-way permits too. The apron and the sidewalk crossing it are often permitted together.

Who is responsible for the sidewalk in front of your house

The sidewalk usually sits on public right-of-way, not on your lot. That is why the permit comes from public works or the transportation department. But owning the land and being responsible for repairs are two different questions, and cities answer the second one differently:

Sources: Portland Bureau of Transportation, San Francisco Public Works, NYC DOT, City of Oakland, Seattle SDOT guide, Sidewalks.LACity.gov, Safe Sidewalks LA, Denver DOTI.

Seattle adds a point many owners miss: you are also responsible for the planting strip, trees must be kept trimmed to leave 8 feet of clearance above the sidewalk, and trees other than city-planted street trees are the abutting owner's to maintain (Seattle SDOT). If you live in one of these cities, our city guides for Portland, Seattle, New York City, Los Angeles, Chicago and Denver cover the building-permit side of projects on the lot itself.

What a sidewalk repair notice means

Notices usually start with a complaint or a scheduled neighborhood survey. In Portland, inspectors investigate a complaint and also look at nearby sidewalks, then send a Sidewalk Repair Notice, which the city describes as a legal affidavit, to every adjacent owner responsible (Portland Bureau of Transportation). San Francisco Public Works sends a Notice to Repair either after a public complaint or when its Sidewalk Inspection and Repair Program reaches your neighborhood (San Francisco Public Works).

What counts as a defect is spelled out, and the thresholds are not the same everywhere:

• Portland cites a vertical step between two sections of one-half inch or more, openings or cracks one-half inch or wider, and spalling (chipped or deteriorated surface) one-half inch deep or more (Portland Bureau of Transportation).
• Oakland says any crack or vertical offset of more than one-quarter inch is considered a defect, pointing to federal ADA guidelines (City of Oakland).
• New York City lists collapsed sidewalk, trip hazards, improper slope, patchwork and hardware trip hazards among the common defects, with the full list in Administrative Code 19-152 (NYC DOT).

Read the notice closely. San Francisco says a posted general notice does not require action on its own; the official Notice to Repair comes by mail and states the square or linear footage to repair and the permits required (San Francisco Public Works). New York City attaches a Preliminary Inspection Report, a sketch on which every numbered sidewalk square must be replaced (NYC DOT). If you got multiple NYC notices, the newest one supersedes the rest.

A notice is also a public record in some places. Portland warns that contractors can see repair notices through the city's records portal and may contact you, and that "there is no financial relationship between the city and private contractors" (Portland Bureau of Transportation). You don't have to hire whoever knocks first.

Deadlines, and what happens if you don't act

Sources: City of Oakland, San Francisco Public Works, Portland Bureau of Transportation, NYC DOT, City of San José.

New York City adds two details worth knowing. There is no fine attached to a sidewalk violation, but a copy is filed with the County Clerk and stays on file until repairs are confirmed, and the city warns it "may complicate selling or refinancing a property." The 75-day period also runs year-round, so schedule a contractor as soon as the weather allows (NYC DOT).

Do you need a permit to repair the sidewalk?

Usually yes, and it is a different permit from the one your building department issues for work on the house. Here is how the cities in this guide handle it:

• Portland: "Sidewalk repair requires a permit," applied for on PBOT's Mandated Sidewalk Repair Permit form. Owners or their contractors may be able to make minimal repairs, but those "still require prior approval" (Portland Bureau of Transportation). If the notice lists obstructions, clear them and get a reinspection before applying, because fees are based on square footage and the revised notice may shrink it.
• San Francisco: a Sidewalk Repair Permit for any sidewalk repair work, obtained before work begins. Work involving the curb, a driveway or existing encroachments needs a Street Improvement Permit instead, which adds a formwork inspection before the concrete is poured and must be done by a qualified concrete contractor. For minor defects, an inspector can approve owner repairs under Public Works Order 177,526 without a permit, but the repair is inspected and, if unacceptable, the city replaces the section and invoices you (San Francisco Public Works).
• Oakland: a city Sidewalk Permit for repairs larger than 25 square feet; the city says a licensed contractor should perform all other repairs (City of Oakland).
• Seattle: the permit depends on size. Under 100 square feet, a Right-of-Way Maintenance Permit; under 2,000 square feet, a Right-of-Way Construction Permit; 2,000 square feet or more, a Street Improvement Permit. Once approved, you contact your district inspector to plan the work (Seattle SDOT guide).
• New York City: a Sidewalk Construction Permit from NYC DOT. Contractors apply online through NYC Streets; private homeowners doing their own repairs can apply by mail with an Affidavit of Ownership (NYC DOT).
• San José: a sidewalk repair permit before any work starts. When the city asks you to repair, the permit comes enclosed with the notice (City of San José).
• Los Angeles: sidewalk, curb and driveway approach repairs that match existing grades go under a Class A-Permit from the Bureau of Engineering (Safe Sidewalks LA).

The pattern is consistent even where the details aren't: the street department wants to approve the work before the old concrete comes out, and it wants to inspect the result. If you are not sure who issues the permit where you live, our 10-minute AHJ permit checklist helps you find the right office, and our guide to who pulls the permit covers the homeowner-versus-contractor question in general.

Permit fees and city repair costs where they are published

Sources: Portland Bureau of Transportation, NYC DOT, City of San José, City of Oakland, San Francisco Public Works, Safe Sidewalks LA.

Those are permit fees, not the cost of the concrete work, which depends on how many squares need replacing and who does it. NYC DOT tells owners to estimate a city repair by multiplying the square footage on the Preliminary Inspection Report by the per-square-foot cost printed on the letter, using the 7-inch concrete price for any driveway area and the 4-inch price elsewhere (NYC DOT). For how permit fees work on projects at the house itself, see how much a building permit costs.

Doing it yourself or hiring a contractor

Some cities let owners pour their own sidewalk; others steer you to a licensed contractor:

• Portland says owners may repair the sidewalk themselves, hire a contractor, or let the city do it and bill them. It publishes a Sidewalk Repair Manual and a standard detail (P-544) for owner repairs (Portland Bureau of Transportation).
• New York City lets private homeowners doing their own work get the permit by mail, but its repair checklist starts with "hire a licensed contractor" and suggests checking the city's licensed contractor database (NYC DOT).
• Oakland says a licensed contractor should perform repairs not covered by its 25-square-foot permit threshold (City of Oakland).
• Los Angeles requires a contractor with an A, C-8, C-12 or C-61:D-06 California license for rebate work, and the city does not pay the contractor directly (Safe Sidewalks LA).
• In San Francisco, a contractor applying on your behalf needs a copy of your Notice to Repair or a Certificate of Authorized Agent (San Francisco Public Works).

Portland's advice on payment is worth copying anywhere: withhold final or full payment until the work passes final inspection, and ask the contractor for the record of that inspection (Portland Bureau of Transportation). If you are weighing doing the work yourself, our guide to owner-builder permits explains the trade-offs, and if the job needs a roll-off container at the curb, our dumpster permit guide covers the separate street-use permit many cities require.

When a street tree caused the damage

Seattle's guide notes that raised, cracked or broken sidewalks are "often caused by tree roots" (Seattle SDOT guide). Tree damage is also where cities differ most:

• New York City: the city does not charge owners of one-, two- and three-family properties for repair of sidewalk damaged by a City tree or its roots, and no longer issues violations to those properties for damage caused solely by City trees. Such properties may be eligible for repair under the Parks Department's Trees and Sidewalks Program. Cutting or shaving the roots of City-owned trees "is strictly prohibited" (NYC DOT).
• Oakland: the city used to take responsibility for uplift from "official" trees. It says the municipal code never recognized that distinction and now holds the adjacent owner responsible. Removing a street tree still needs Public Works Tree Services approval (City of Oakland).
• Seattle: damage from street trees (between the property line and the road) "require extra steps." Contact an SDOT arborist before starting work (Seattle SDOT guide). Street trees planted by the city are maintained by the city; all other trees are the abutting owner's to maintain (Seattle SDOT).
• Los Angeles: for rebate repairs, a City Arborist decides whether the tree can stay with root pruning or a bigger planting area, or must be removed. City policy replaces two street trees for every one removed, and a stump removal earns a standard $279 rebate per stump (Safe Sidewalks LA).

The practical rule: don't let anyone cut roots or remove a tree in the parkway until the city's arborist or forestry office has signed off. In several of these cities the street tree is regulated by the city even though it sits in front of your house. Our guide to protected tree removal permits explains how street trees and private trees are treated.

Cost-share programs, rebates and payment plans

Before paying full price, check whether your city helps:

• Chicago: the Shared Cost Sidewalk Program is voluntary. Owners share the cost with the city at a per-square-foot price the city says is "well below what a private contractor would charge." Applications are first-come, first-served through 311, the program typically fills quickly, and past applicants must reapply each year (Chicago CDOT).
• Los Angeles: the Safe Sidewalks LA rebate reimburses part of a voluntary repair, up to $12,400 per lot for residential properties (effective August 25, 2023). Work mandated by a building permit is not eligible, the repair must go through a linked "no fee" Class A-Permit, and new applications are currently waitlisted because of funding restrictions (Safe Sidewalks LA). After the city issues a Certificate of Compliance, a 20-year residential warranty period begins; when it ends, or after one city warranty repair, maintenance shifts to the owner.
• Portland: if the city makes the repairs, financing is available: five or 10 years for assessments up to $2,500, and five, 10 or 20 years above that (Portland Bureau of Transportation).
• New York City: owners can request a payment plan for a city-performed repair through a Department of Finance Business Center or 311 (NYC DOT).
• Oakland: a Sidewalk Assistance Program supports qualified property owners (City of Oakland).
• Denver: the city repairs sidewalks through a prioritization process rather than on request. Every property pays a flat sidewalk service charge, $150.00 for 2026, plus $3.50 per foot of frontage over 230 feet, billed with stormwater, with income-based rebates (Denver sidewalk billing).

Sidewalk repairs when you sell, buy or remodel

A sidewalk problem can surface at the worst time. Oakland says you must repair your sidewalk if you are buying or selling the property, or if you are performing a renovation valued at more than $100,000 (City of Oakland). In New York City, an open violation stays on file with the County Clerk and may complicate a sale or refinancing until the repair is confirmed (NYC DOT). Los Angeles excludes sidewalk work mandated by a building permit from its rebate, a sign that sidewalk work can be required as part of other permits (Safe Sidewalks LA).

If you are buying, add the sidewalk to the questions you ask during a permit history check. If you are selling, an open sidewalk violation belongs on the same list as other open issues buyers ask about, which our guide to selling a house with unpermitted work covers. The same goes for work that reaches the street, such as a water service line or sewer line replacement: the trench under the sidewalk is restored under the right-of-way permit for that job.

Liability: why the notice matters even without a fine

New York City says owners are "potentially liable for personal injuries caused by their failure to maintain the sidewalk free of defects" under Administrative Code section 7-210 (NYC DOT). Oakland puts it more bluntly: "If someone trips in front of your house, you could be sued for damages" (City of Oakland). Los Angeles, asked who is liable after a certified rebate repair, says there are many factors and "we cannot answer this question" (Safe Sidewalks LA).

So treat a notice as a safety and insurance issue, not just paperwork. Keep the notice, the permit, photos before and after, and the final inspection record. Our article on homeowners insurance and unpermitted work explains why a paper trail matters when a claim comes up.

If you think the notice is wrong

Most cities give you a way to question a notice, and the window is usually tied to the repair deadline:

• New York City: if the defect on the notice doesn't match the sidewalk, request a re-inspection within 75 days of receiving it. Check the Preliminary Inspection Report against your property's width, trees, signs, utility caps and cellar doors; if the details don't match, appeal through 311. A different inspector does the re-inspection, which is final, and DOT schedules it within 180 days of the appeal. A violation issued to the wrong owner is also appealed through 311 (NYC DOT).
• San Francisco: questions about the inspection, existing defects or 30-day extensions go to the district inspector named on your notice (San Francisco Public Works).
• Portland: if the notice lists obstructions you have since cleared, request a reinspection; you will get a revised notice that may reduce the repair area and the permit fee (Portland Bureau of Transportation).

Disagreements with a building inspector follow a different path; see how to appeal an inspector decision. And if the notice came after a neighbor's complaint, our guide to what happens after a neighbor complaint explains how complaint-driven inspections usually work.

Step by step: what to do when the notice arrives

1. Write down the deadline and how it is counted (mailing date, receipt date or posting date).
2. Compare the notice with the sidewalk. Count the marked squares, check the measurements and note any trees, obstructions or utility covers.
3. Decide whether to contest or request a reinspection, and do it inside the window.
4. Check for a street tree. If roots caused the damage, call the city arborist or forestry office before anyone cuts roots.
5. Check for help: cost-share, rebate, assistance or city-repair options, before signing a contract.
6. Get quotes from contractors who know the city's sidewalk standards. You don't have to use one who contacted you.
7. Pull the right permit from the street or transportation department before the old concrete comes out.
8. Get the final inspection or dismissal inspection, and keep the record. Pay the final balance after it passes.

FAQ

Do I need a permit to fix the sidewalk in front of my house?

In most of the cities in this guide, yes, from the street or transportation department. Portland, San Francisco, San José, Seattle and New York City require one for sidewalk repairs; Oakland requires one above 25 square feet. San Francisco lets an inspector approve some minor owner repairs without a permit, but they are still inspected.

Can I just grind down the trip hazard?

Sometimes, with approval. San José lists a $0 permit fee for grinding the owner has completed, and Portland says minimal repairs may be possible with prior approval. Portland's own city crews only replace full squares. Ask before you grind.

What happens if I ignore a sidewalk repair notice?

In Portland and New York City, the city can hire a contractor and bill you; San José adds a $25 late fee to the permit. In New York City, unpaid bills accrue interest after 90 days and a lien is placed on the property.

Who pays when a city tree lifted the sidewalk?

It depends on the city. New York City doesn't charge owners of one-, two- and three-family homes for damage caused by City trees. Oakland holds the adjacent owner responsible regardless.

Is my homeowners policy involved?

Liability for a trip-and-fall can land on the owner in some cities, so keep records of the notice, permit and final inspection, and ask your insurer how your policy treats the sidewalk.

Does a sidewalk permit extend my repair deadline?

Not in New York City: DOT says a sidewalk permit does not extend the 75 days (NYC DOT).

Bottom line

A sidewalk repair notice is a deadline, a permit and an inspection, usually from a city office you have never dealt with. Check who is responsible where you live, read the notice carefully, deal with any street tree through the city first, look for a cost-share or rebate, and get the street permit and final sign-off on record. A small concrete job done in order is much cheaper than a city bill or a lien.
