How Much Does It Cost to Pave a 100,000 Sq. Ft. Parking Lot?

(2026 Long Form Buyers Guide)

Why this is a long-form guide

Most articles about paving give you a quick price and move on.

That’s not how major capital decisions should be made.

This guide is intentionally detailed.

We walk a real 100,000 sq. ft. parking lot together, explain what actually fails, show what most contractors miss, and break down real New Jersey pricing so you can make an informed decision — not just chase the lowest number.

If you’re just looking for a quick ballpark, we also have a short version.

But if you want to understand paving the right way before spending hundreds of thousands of dollars, this is the guide to read.

Short Answer (What You Came Here For):

Milling & Paving a 100,000 sq. ft. commercial parking lot in 2026 typically costs:

✔ $190,000 – $450,000

Quick Answer 

Bare 2" mill & pave only:
💲 $1.90 – $2.50 per square foot

For 100,000 sq ft:
💲 $180,000 – $250,000

But most real projects:
💲 $250,000 – $450,000+ depending on repairs and prep work

The difference is always what’s happening underneath the asphalt.

So What Does a Real 100,000 Sq. Ft. Paving Project Usually Cost?

After walking dozens of lots across New Jersey, here’s what we’ve learned:

Very few commercial properties only need “mill and pave.”

That’s the surface layer.

But most older parking lots also need structural fixes underneath — the stuff you don’t see until you actually walk the site.

So when you scope a project correctly — not just price it by square foot — the real-world budget usually looks something like this:

💲 Typical 100,000 Sq. Ft. Paving Budget Breakdown

2" Milling & Paving (surface only):
$190,000 – $250,000

Full-depth box-out repairs (failed areas):
$13 – $20 per SF of affected areas

Underdrain / underground water remediation:
$60 – $80 per linear foot

Catch basin rebuilds:
$2,500 – $5,000 per basin

ADA concrete stalls, paths of travel & compliant signage:
$9,000 – $13,000 per stall

Additional drainage or subgrade stabilization:
Costs vary depending on severity and site conditions

What this typically means in the real world

Most 100,000 sq. ft. lots we evaluate land somewhere between:

🏦 $250,000 – $450,000+

Depending on how much structural work is required.

Some come in lower if the base is solid.
Some go higher if there are drainage or foundation problems.

But almost never does a large NJ lot only need “just paving.”

And that’s exactly why we walk every site first.

Because once you understand what’s underneath…

The price makes a lot more sense — and the pavement lasts a lot longer.

Now let’s walk through EVERYTHING you need to know to get this right — transparently — from a contractor who has spent 30 years maintaining commercial asphalt.

Let’s Walk Through a Typical 100,000 Sq. Ft. Paving Project Together

Instead of throwing numbers at you or emailing a quote from behind a desk, let’s do something more helpful. Imagine we’re standing side-by-side in a real 100,000 square foot parking lot somewhere here in New Jersey. We’re not talking price yet. We’re just walking the site like engineers and asking simple questions: Where is water collecting? Where is the base failing? Which areas are structurally sound and worth saving? Are the drains solid? Are slopes ADA compliant? What will last 20 years — and what will fail in two? That’s exactly how we scope every project. Because before you can price paving correctly, you have to understand what the pavement is trying to tell you. So let’s walk the lot together and I’ll show you exactly what we look for — and what most contractors never point out.

Ready?

Let’s dive in. 👊

How Much Does Asphalt Paving Alone Cost for 100,000 Sq. Ft.?

(Assuming the asphalt base is in good condition, there are no drainage issues present, and the ADA parking stalls are compliant)

Asphalt Milling & Asphalt Paving Price Range For New Jersey (2026):

$190,000 – $250,000
👉 ($1.90 – $2.50 per sq. ft.)

You will usually get:

• Barricades,  traffic control, and work area protection

• Milling of the asphalt from a depth of 1" - 2.5", depending on grades and water flow, along with sweeping for site clean-up

• Application of a tack coat for bonding the old asphalt to the new asphalt

• Installation of new plant hot mix asphalt (NJDOT I-5/9.5 mm) installed at a rate of 2"-2.5" loose and compacted to 1.5" - 2."

• Service is typically completed after line striping, which can range in cost from $0.05 - $0.10 square foot in addition to the pricing above

• Jobsite cleanup and final walkthrough to verify punch list items.  

That’s the correct process for surface replacement.

And if your lot truly only needs that…

Great — that’s the best-case scenario.

But here’s the part most contractors won’t explain

Milling and paving is only the top layer.

It’s the cosmetic finish.

It’s not the structure.

And after walking thousands of commercial properties across New Jersey, we can tell you honestly:

Very few large parking lots only need paving.

Because nearly every lot has something else going on underneath:

• trapped water
• soft base areas
• alligator cracking
• aging catch basins
• ADA slope issues
• settlement
• drainage problems

And those issues don’t show up in a “price per square foot” bid.

They only show up when someone actually walks the lot and looks, AND has the technical expertise to design a solution.

Let's dig into it deeper 👊

Underground Water Remediation Cost 

Underground Water Remediation Price Range:

$60.00 – $80.00 per linear foot

Why Underground Water Remediation Is So Important (And Why Most Paving Jobs Fail Without It).

When we walk a parking lot with a client, the very first thing we look for isn’t cracks.

It isn’t potholes.

It isn’t even the asphalt.

It’s water.

Water — not traffic — is what destroys parking lots.

Every time.

Here’s what most people don’t realize

Asphalt is not waterproof.

It’s water-resistant.

There’s a big difference.

Water slowly works its way through:
• cracks
• joints
• edges
• utility cuts
• old patches

Once it gets underneath, it sits in the base.

And that’s where the real damage begins.

What happens when water gets trapped under pavement?

Especially here in New Jersey, where we deal with clay soils and constant freeze–thaw cycles.

This is the chain reaction we see all the time:

1. Water enters the base
2. Subgrade softens and loses strength
3. Vehicles flex the pavement
4. Base starts pumping mud upward
5. Asphalt cracks
6. Water gets in faster
7. Failures accelerate

Now what started as a small moisture issue turns into:

• alligator cracking
• potholes
• settlement
• sinkholes
• premature failure

And suddenly that “brand new paving job” looks terrible in two winters.

This is why paving over wet areas doesn’t work

Let’s say a contractor simply mills and paves.

The surface looks beautiful.

Fresh black asphalt.

Nice straight lines.

Everything looks perfect.

But underneath?

The water is still there.

So what happens?

The new asphalt flexes over soft spots.

And within 12–24 months:

The cracks come right back.

Not because the paving was bad.

Because the foundation was never fixed.

It’s like putting hardwood floors over a wet basement.

It looks great…

Until it doesn’t.

What to do differently

When we see persistent wet areas, pumping, or soft subgrade, we don’t price paving yet.

Because paving isn’t the solution.

Drainage is.

We typically recommend:

• underdrain systems
• trench drains
• stone backfill
• proper outlets
• regrading low spots

The goal is simple:

Get the water out first. Then pave.

Not the other way around.

💲 Typical NJ Underdrain Pricing

A few hundred linear feet of drainage can easily add $15,000–$25,000 to a project.

And here’s the honest truth:

Some contractors avoid bringing this up…

Because it raises the price.

And higher prices lose bids.

But skipping drainage almost guarantees early failure.

So you don’t actually save money.

You just delay the expense.

The simple rule we follow

If water is present…

Paving is cosmetic.

Drainage is structural.

And structural issues always come first.

Bottom line

If you remember one thing from this guide, make it this:

Asphalt doesn’t fail from the top down.

It fails from the bottom up.

Control the water… and your pavement lasts decades.

Ignore the water… and you’ll be paving again soon.

That’s why the very first thing we look for when walking any lot isn’t asphalt.

It’s where the water is going.

Catch Basin Repair Cost

Why Catch Basin Inspections Should Always Happen Before Milling

Catch Basin Rebuild Costs:

$2,500.00 – $3,500.00 per basin

Here’s something almost no one tells property managers before a paving project starts:

Why Box-Out Repairs Matter (And Why Milling Alone Won’t Fix Base Failure)

Boxout Repair Price Range:

$13.00 - $20.00 per square foot

As we keep walking the lot together, there’s one thing we always look for next.

Not potholes.

Not surface cracks.

We look for alligator cracking.

That spiderweb, scaly-looking pattern in the asphalt.

Because when we see that?

We already know something important.

The problem isn’t the asphalt.

It’s the foundation underneath it.

What alligator cracking really means

A lot of people assume those cracks just mean:

“The pavement is old.”

But that’s not what it means at all.

Alligator cracking is structural failure.

It tells us:

• the base is soft
• the subgrade has lost strength
• water has weakened the foundation
• the pavement is flexing under traffic

In other words…

The ground underneath can’t support the load anymore.

And once that happens, no amount of new asphalt on top will fix it.

Here’s where most paving jobs go wrong

This is something almost every property manager has experienced at least once.

A contractor says:

“We’ll just mill and pave the lot.”

It looks great on day one.

Nice, smooth, jet black asphalt.

Then one winter later?

Those same cracks come right back.

Same spots.

Same pattern.

Why?

Because milling only removes the top 2 inches.

It doesn’t fix what’s broken below.

So you’re basically putting a fresh coat of paint over a cracked wall.

It hides the problem.

It doesn’t solve it.

The correct fix is called a box-out repair

When we identify structural failure, we don’t just resurface.

We rebuild.

That means:

• saw cut the damaged area
• remove existing asphalt
• remove 6–12 inches of failed subgrade
• install soil stabilization fabric
• add recycled concrete aggregate base
• compact properly
• install 4" binder asphalt
• then pave the surface

Now you’ve rebuilt the foundation — not just the top.

That’s the difference between:

A patch that lasts 1–2 years
and
A repair that lasts 15–20+ years

Why many contractors skip this conversation

Because box-outs increase the price.

And when the industry competes on “lowest bid,” anything that raises the number risks losing the job.

So some contractors simply don’t bring it up.

They price everything as mill & pave.

Hope for the best.

And deal with callbacks later.

But that’s not a strategy.

That’s gambling.

💲 Typical NJ Box-Out Pricing

So if we find:

2,000 SF of failure → $26,000 – $40,000
3,000 SF → $39,000 – $60,000

It’s not cheap.

But it’s far cheaper than paving twice.

How we explain it to clients

We usually say:

“If we don’t fix this now, you’ll be looking at these same cracks through your brand-new pavement next winter.”

Once you see it that way, it makes sense.

Because you’re not paying for asphalt.

You’re paying for lifespan.

Bottom line

Milling fixes the surface.

Box-outs fix the structure.

And structure always wins.

If the base is bad, nothing above it matters.

That’s why we’d rather show you exactly where these areas are while walking the lot — instead of pretending everything is fine and letting the pavement fail later.

Why ADA Compliance Should Be Addressed Before You Pave (Not After)

ADA Upgrade Price Range:

$19,000.00 t0 $13,000 per ADA parking stall

As we finish walking the lot, there’s one more thing we always check before talking about paving.

And it surprises people every time.

It’s not asphalt thickness.

It’s not cracks.

It’s ADA compliance.

Because paving isn’t just about making the lot look good.

It’s also about making sure the property is safe, accessible, and legally compliant.

And this is where a lot of older parking lots quietly fail.

Here’s what we see all the time

Especially across older properties in New Jersey:

• slopes that are too steep
• uneven transitions to sidewalks
• low or faded signage
• improper striping layouts
• settled asphalt around stalls
• patched areas creating trip hazards

From a distance?

It looks fine.

But when we put a digital level on it…

It’s out of tolerance.

And technically?

Non-compliant.

Why this matters more than most people realize

Potholes are annoying.

Cracks are cosmetic.

But ADA issues?

Those can become legal problems.

If someone trips, falls, or files a complaint, the question isn’t:

“Did it look okay?”

It’s:

“Was it compliant?”

That’s a very different conversation.

And unfortunately, we’ve seen property owners forced into expensive corrections later simply because no one addressed it during paving.

Here’s the mistake many contractors make

A lot of paving contractors treat ADA like striping.

They’ll say:

“Don’t worry — we’ll paint the handicap symbols back.”

But paint doesn’t fix slopes.

Paint doesn’t fix settlement.

Paint doesn’t fix accessibility.

If the asphalt underneath isn’t right, the striping doesn’t matter.

And here’s something most people don’t know:

Asphalt is hard to fine-tune for precise slopes.

Even if we shape it perfectly…

The vibratory rollers used during paving can slightly shift grades.

Sometimes just enough to push it out of compliance.

Concrete, on the other hand?

Holds shape exactly.

What we typically recommend instead

For dedicated ADA areas, we often suggest:

• concrete parking stalls
• concrete access aisles
• concrete paths of travel
• proper transitions to sidewalks
• compliant signage
• high-intensity reflective markers
• protected bollards

Concrete gives you:

• precise slopes
• long-term durability
• minimal settlement
• easier inspections
• lower long-term maintenance

In other words…

Set it once and forget it.

💲 Typical NJ ADA Upgrade Pricing

So if you have 4 stalls:
$36,000 – $52,000

It’s not a small number.

But compared to:
• lawsuits
• rework
• tearing up brand-new asphalt later

It’s usually the smarter move.

How we explain it to clients

We usually say:

“If we’re already mobilized, already paving, already improving the lot… this is the time to fix ADA permanently.”

Because doing it later means cutting into fresh asphalt you just paid for.

And nobody wants that.

Bottom line

Paving makes your lot look new.

ADA compliance makes your lot safe and defensible.

Both matter.

But only one protects you legally.

That’s why we always evaluate accessibility before we pave — not after the striping truck leaves.

Why We’d Rather Walk the Lot With You Than Just Email You a Quote

Let me explain something that might sound a little unusual coming from a paving contractor.

If you call FixAsphalt.com and ask:

“Can you just send me a number for paving?”

There’s a good chance we’ll say:

“Before we price anything… can we walk the lot with you first?”

Not because we’re trying to make the process longer.

And definitely not because we’re trying to sell you something.

It’s actually the opposite.

It’s because we want you to be fully informed before you buy anything.

Here’s the truth most contractors won’t say out loud

About 90% of paving contractors in New Jersey bid work like this:

Measure the lot
Multiply by a unit price
Send a proposal

Done.

No drainage discussion.
No base inspection.
No basin checks.
No ADA review.
No explanation.

Just a number.

And on the surface, that feels efficient.

Until two winters later… when the lot starts failing again.

Why does this happen?

Not because those contractors are bad people.

It’s because the industry has been trained to compete on one thing:

Lowest price wins.

So if a contractor takes the time to:
• talk about underdrains
• explain base failures
• recommend box-out repairs
• rebuild basins
• fix ADA compliance

Their number goes up.

They lose the job.

So most simply don’t bring it up.

Not because it’s unnecessary…

Because it’s inconvenient to the sale.

But here’s how we look at it

We don’t see paving as a “quote.”

We see it as:

Helping someone make a six-figure capital decision correctly.

If you’re about to spend $200,000… $300,000… sometimes $500,000+…

Wouldn’t you want to know:

• what’s actually wrong
• what can be saved
• what must be fixed
• what’s optional
• what happens if you skip something
• and how long it should realistically last

That’s not selling.

That’s teaching.

And that’s exactly how we approach it.

So when we say “let’s walk the lot together”…

Here’s what we really mean

We want you standing next to us while we point things out.

“See this area? Water is trapped underneath.”
“This cracking means the base failed.”
“These basins are about to collapse during milling.”
“This slope won’t pass ADA.”

Because once you see it with your own eyes…

You’ll never look at paving as “price per square foot” again.

You’ll start looking at it like:

“What’s the right way to fix this so I don’t deal with it again for 20 years?”

That’s a totally different buying mindset.

Who this article is actually for

This guide isn’t really written for professional procurement teams who buy paving every day and just want the lowest number.

They already have systems and preferred vendors.

That’s fine.

This is for people like:

• a commercial property manager frustrated that past jobs didn’t last
• a facility manager responsible for one large site
• a church board member trying to steward donations wisely
• a nonprofit making a once-every-20-years decision
• a commercial property owner who simply wants it done right the first time

People who may not live in the paving world…

But want to understand it before spending serious money.

If that’s you — this guide is exactly why we wrote it.

And if you’re just shopping for the cheapest number…

We’re probably not your contractor.

And that’s okay.

There are plenty of companies who will gladly email you a low price.

We’d rather be the company that helps you make the smartest decision.

Even if that means you don’t hire us.

Because educated buyers make better long-term choices.

And that’s how trust is built.

Our philosophy in one sentence

Before we ever ask for your business…

We want you to understand your parking lot better than anyone else.

That’s how you protect your asphalt.

And that’s how we earn the right to work with you.

If you’ve made it this far, you probably noticed something.

This isn’t a typical “paving contractor” article.

We didn’t throw out a cheap number.
We didn’t push a quick quote.
We didn’t promise to be the lowest bidder.

Instead, we walked a real parking lot together.

We showed you:
• what actually fails
• what most contractors skip
• what it really costs to do it right
• and how to protect your asphalt for the next 15–25 years

Because that’s how we believe paving decisions should be made — informed, not rushed.

Here’s how we work

Before we ever talk price, we prefer to meet you on-site.

Not to sell you.

To educate you.

We’ll walk the property together and point things out in plain English:

“Here’s where water is getting trapped.”
“This section needs full-depth repair.”
“These basins should be rebuilt before milling.”
“Your ADA slopes are close, but not compliant.”
“This area is solid — you don’t need to touch it.”

Sometimes we recommend less work than you expected.

Sometimes more.

But it’s always honest.

Because our goal isn’t to win the job today.

It’s to make sure the pavement lasts so you don’t have to think about it again for decades.

Who we’re a great fit for

We tend to work best with:

• commercial property managers
• facility managers
• churches and schools
• HOAs and associations
• owners responsible for long-term assets
• anyone tired of paving jobs that don’t last

If you’re looking for the cheapest number only, we’re probably not the right fit.

But if you want clarity, transparency, and a plan that makes sense long-term…

We’d love to help.
