Part of this walk may not be yours, and you are probably still responsible for it

The strip of land between your property line and the street — the one the public sidewalk runs through, often with a planting strip beside it — is usually public right-of-way owned by the municipality. Your lot line is typically at the back of it, not at the curb.

What follows from that catches people out:

That last point varies more than anything else here, so check with your city before assuming either way. The question to ask is specifically: who is responsible for repair, and who is liable for injury? A single phone call, and the answer changes whether this is a project you choose or one you are obliged to do.

Where the walk is entirely inside your own lot — the path from the driveway to the front door — none of this applies. No permit, no city spec, your call.

The geometry that makes a walk a walk

These numbers come from accessibility standards, which do not legally apply to a private home. Use them anyway; they describe what makes a path comfortable rather than merely passable:

Joints every 4 to 5 feet on a 4 foot walk, so the panels come out roughly square. A long thin panel cracks across its middle, and on a 4 foot walk jointed at 10 feet you will get a crack in the middle of every one.

Before you replace it, find out whether it can be lifted

A walk that has failed along its whole length needs replacing. A walk with two bad joints usually does not, and the difference is thousands of dollars.

Replacing the whole walk makes sense when the panels are cracked through in multiple places, when the base has washed out, when the slope is wrong, or when enough panels have moved that fixing them individually costs more than starting again.

Get the lifting quote before the replacement quote. A contractor who only pours concrete will quote you a pour.

What lifted it is almost certainly a tree

Tree roots are the leading cause of sidewalk failure, and they are the reason a replacement can fail again in five years if the cause is not addressed.

What works, roughly in order of how well:

If the tree is a street tree in the right-of-way, it is probably the city's, and cutting its roots may need their permission regardless of who is paying. Ask before anybody turns up with a saw.

What you are paying for

For a 40 foot walk at 4 feet wide on bare ground, at $2,150:
Concrete, about 2 cubic yards around $335
Base stone, mesh, forms and curing around $200
Labor, about 15 crew hours around $800
Permit allowance and hauling the spoil around $250
Overhead and margin the balance

The concrete is about a sixth of it. This is a forming and finishing job, and the forms are the work: a walk is nearly all edge, so a 160 sq ft walkway has more linear feet of form per square foot of concrete than any other slab on a property.

Short walks are priced as a job, not as an area

The figure per square foot and per linear foot both climb sharply as the walk gets shorter, and this is real rather than an artifact:
20 ft walk, 80 sq ft around $1,525 $76 a linear foot
40 ft walk, 160 sq ft around $2,150 $54 a linear foot
60 ft walk, 240 sq ft around $2,750 $46 a linear foot
100 ft walk, 400 sq ft around $3,975 $40 a linear foot

Published figures of $25 to $50 a linear foot describe the longer end of that. For a 20 foot path the crew still mobilizes, excavates, forms both edges, lays base and steel, pours, finishes, and comes back the next morning to cut the joints. There is no version of that which costs $600.

Two ways to improve a short walk's economics:

Four inches, and specify the mix

Four inches with welded wire mesh is the standard sidewalk and nearly always right. A walk carries people; the loads that justify a thicker slab elsewhere are not on it. The exceptions are where it crosses a driveway or an alley so vehicles drive over it, and where the soil is expansive clay or poorly drained fill.

On the mix, a walk deserves more attention than its size suggests, because it is the surface that gets salted:

Questions worth asking

Common questions

How much does a concrete sidewalk cost?

About $2,150 for a 40 foot walk at the standard 4 foot width — 160 sq ft — with most jobs that size falling between $1,750 and $2,650. That works out to roughly $13.45 per square foot or $54 per linear foot. Longer walks come in lower per foot: 60 feet is about $46 a linear foot and 100 feet about $40. Replacing an old walk rather than pouring on bare ground adds around $525 on a 40 foot run.

How much does a sidewalk cost per linear foot?

Between $40 and $76 a linear foot at the standard 4 foot width, depending almost entirely on length. A 100 foot walk is about $40 a foot, a 60 foot walk $46, a 40 foot walk $54, and a 20 foot path about $76. Published figures of $25 to $50 describe the longer end. The reason short walks cost so much per foot is that the crew still mobilizes, forms both edges, lays base and steel, pours, finishes and returns the next morning to cut joints, whether the walk is 20 feet or 100.

Who is responsible for the sidewalk in front of my house?

Usually you, even though the land is usually not yours. The strip between your property line and the curb is typically public right-of-way owned by the municipality, but in most US cities the abutting property owner is responsible for keeping the sidewalk in repair, and in many of them can be liable if somebody is injured on it. Some cities share the cost or run cost-sharing programs and a few take it on entirely, so this varies more than anything else about the job. Call your city and ask specifically who repairs and who is liable.

Do I need a permit to pour a sidewalk?

For the public portion, almost always — commonly $100 to $500, usually with an inspection, and the city will specify the thickness, jointing, width and sometimes the mix. Those specs override any general guidance, and a walk poured wrong in the right-of-way can be ordered out and redone. For a path entirely inside your own lot, from the driveway to the front door, no permit is normally needed and the choices are yours.

How wide should a walkway be?

Four feet is the standard and the right default. Thirty-six inches is the practical minimum and lets two people pass awkwardly; five feet is generous and reads as deliberate. Going from three feet to four on a 40 foot walk adds 40 square feet that is mostly concrete, so it costs far less than the per-square-foot figure suggests — and it is the difference between a path and a walk. If there is a landing at the door, measure it separately; it is usually 25 to 40 sq ft and it is the part people forget.

How much slope should a sidewalk have?

Cross slope no more than 2%, which is a quarter inch per foot — enough to shed water, little enough that it is not noticeably off-camber underfoot. Running slope should stay under 5% without handrails; steeper than that and the right answer is steps rather than a steeper walk. These figures come from accessibility standards that do not legally bind a private home, but they describe what makes a path comfortable rather than merely passable.

How big a lip in a sidewalk is a trip hazard?

A quarter of an inch is the threshold. Anything over a quarter inch at a joint should be beveled, and anything over half an inch needs a ramp or a repair. That number matters beyond comfort: it is what an injury claim on a public sidewalk will be measured against, and in most cities it is the abutting owner who is exposed. Grinding or sawing the lip is often enough to clear it, at a few hundred dollars rather than the cost of a new walk.

Can a settled sidewalk be raised instead of replaced?

Often, yes, and it is the first thing to price. Slab lifting — polyurethane foam or grout injected through small holes to raise a panel back to level — runs roughly $300 to $800 per slab and takes an afternoon. If the panel itself is sound and has simply dropped or tipped, that is the answer rather than a pour. Get the lifting quote before the replacement quote, because a contractor who only pours concrete will quote you a pour.

When should a sidewalk be fully replaced?

When the panels are cracked through in several places, when the base underneath has washed out, when the slope is wrong and water runs the wrong way, or when enough panels have moved that fixing them one at a time costs more than starting again. A single bad joint, a lifted panel or a lip is a repair. One more consideration: a replacement panel will not match the color of twenty-year-old concrete and never will, so if appearance matters, a run replaced whole looks better than a run patched.

What do I do about tree roots lifting my sidewalk?

Address the cause or the new walk will fail the same way. Rerouting the path around the root zone is cheap at the forming stage and permanent. A root barrier — a rigid panel set 18 to 30 inches deep between tree and walk — redirects new roots downward and is best installed while the walk is open. Root pruning is a last resort: cutting roots inside the drip line destabilizes a mature tree and can kill it, and anything over about two inches is an arborist decision. A thicker slab does not help — roots lift six inches as readily as four.

Can I cut the roots of the tree by the sidewalk?

Not necessarily on your own authority. If the tree stands in the right-of-way it is probably the city's, and cutting its roots may need their permission regardless of who is paying for the walk — some municipalities require an arborist report first. Even on your own tree, cutting roots inside roughly the drip line risks destabilizing it, and a mature tree that fails later is a far larger problem than a lifted panel. Ask before anybody turns up with a saw.

How thick should a sidewalk be?

Four inches with welded wire mesh, which is the standard and nearly always right — a walk carries people, and the loads that justify a thicker slab elsewhere are not on it. Go thicker only where the walk crosses a driveway or alley so vehicles drive over it, or where the soil is expansive clay or poorly drained fill. For the public portion of a walk the municipality usually specifies the thickness, and that spec wins over any general guidance.

What concrete mix should a sidewalk be?

4,000 psi, and air entrained wherever the ground freezes. Air entrainment is microscopic bubbles that give freezing water somewhere to expand, and it is the single thing that stops the surface spalling off after a few winters. It is also the item most often left off a small quote, so ask for it by name. Keep de-icing salt off entirely through the first winter and go easy afterwards; sand gives grip and does no damage at all.

How can I make a short walkway cheaper?

Pour it with other concrete work. A front walk done the same day as a patio or a driveway shares one mobilization and one concrete delivery, and the short piece can come in around 30% below its standalone price — easily the largest saving available on this job. Beyond that, there is not much: at 20 feet the crew still forms both edges, lays base and steel, pours, finishes and returns to cut joints, and there is no version of that which costs $600.

Where these numbers come from

Nothing here is copied from a contractor directory. Labor is priced from what the trades are actually paid, materials from published producer prices, and both are adjusted to your area using federal cost-of-living data.
