There's no single honest number, but there is honest logic, and that's more useful anyway. A new asphalt driveway costs more per square foot than resurfacing an existing one, which costs more than sealcoating, which costs a small fraction of either. Where your job lands inside those tiers depends mostly on two things: how thick the new asphalt needs to be, and how much of what's underneath has to be fixed before anyone can pave over it. Everything below explains the logic. The actual number for your driveway or lot comes from someone standing on it, not a page on the internet.
Two variables move the number more than anything a homeowner tends to ask about first, which is usually the brand of asphalt or the color of the sealcoat. The first is thickness: a driveway built for passenger cars needs less asphalt depth than a fire lane built for a garbage truck, and more material costs more money in a fairly straightforward way. The second, and the one that catches people off guard, is the condition of the base underneath. A gravel or dirt surface with good drainage and stable soil needs relatively little prep. A driveway sitting on a saturated, eroded, or poorly compacted base needs excavation, new aggregate, and compaction before a single ton of asphalt goes down, and that groundwork often costs more than the paving itself.
These are three different jobs wearing the same word, paving, and the price per square foot reflects how much structure each one actually adds.
A new pave, sometimes called full-depth paving, starts from bare ground or from an old surface stripped down to the base. It means new aggregate base, compaction, and a full asphalt section built up in one or two lifts. It's the most expensive tier per square foot because it includes both the structural work and the surface.
An overlay skips most of that. If the existing pavement is cracked and worn but the base underneath is still sound, a contractor can clean or grind the old surface and lay a new asphalt layer directly on top of it. No excavation, no new base rock, which is why an overlay typically runs a fraction of what a full new pave costs per square foot. The catch is that an overlay only works if the base is actually still good. Lay fresh asphalt over a failed base and the same cracks come back within a season or two, just wearing new pavement.
Sealcoating isn't paving at all in a structural sense. It's a thin protective coating applied to existing asphalt that's still sound, and it costs a small fraction of either paving option because there's no material depth involved, just a coating pass. It protects the investment you already made. It doesn't add any.
Because they're not cosmetic, they're structural, and structural shortcuts are expensive to skip and even more expensive to fix later. Asphalt over a weak base doesn't just look thin, it fails early: it ruts under the weight of vehicles, cracks along stress points, and eventually alligator-cracks its way back to needing the exact excavation work that got skipped the first time. A contractor quoting a suspiciously low number for a full repave is often quoting thin asphalt over minimal base prep, which is a repair bill in two or three years wearing a paving contract today. On the other end, a job that calls for extra base depth, maybe a hillside driveway or a lot that sees delivery trucks, costs more upfront because the extra rock and compaction time are real costs, not upsells.
Mobilization. Getting a paver, a roller, a crew, and a load of hot-mix asphalt to a job site costs roughly the same whether the crew is there for two hours or two full days, and hot mix has to be used shortly after it leaves the plant, so a contractor can't just bring a little. Most paving companies build a minimum job charge into small jobs for exactly this reason, often in the low thousands of dollars regardless of how small the driveway actually is. That's not a markup aimed at you specifically. A 40,000-square-foot HOA lot spreads that same fixed cost across a lot more square footage, which is why the per-square-foot price on a big commercial job often looks better than the per-square-foot price on a single driveway, even though the driveway remains the cheaper job overall.
The ranges below reflect what shows up across the paving industry generally, not a quote for your property. Treat them as a starting point for a conversation, not a number to hold a contractor to before they've seen your site.
| Job Type | Typical Range | What Changes the Number |
|---|---|---|
| New asphalt driveway (full-depth) | $3 to $7 per square foot | Base condition, thickness, equipment access |
| Asphalt overlay | $2 to $4 per square foot | Whether the existing base actually passes inspection |
| Sealcoating | Well under $1 per square foot | Lot size, number of coats, prep work needed first |
| Patch or pothole repair | Priced per repair on small jobs, not per square foot | Depth of the failure, number of spots, access |
| Concrete driveway | Generally higher than asphalt per square foot | Finish, reinforcement, thickness, forming complexity |
In a climate that fades and oxidizes asphalt as fast as this one does, yes, almost always. A driveway or lot that never gets sealcoated ages faster under constant UV exposure, and small surface cracks that would have taken a sealcoat and a few hundred dollars to manage turn into base-level damage that needs a patch, and eventually a section of full-depth repair. None of that is unique to Chula Vista. It's just that the sun here doesn't take a season off, so the neglect timeline compresses. Budgeting a small amount for sealcoating every couple of years is cheaper, by a wide margin, than paying for a full repave five years earlier than it should have been necessary.
Often, yes, and it's worth budgeting separately from the paving bid itself. Chula Vista, like most California cities, requires an encroachment permit for driveway work that touches the sidewalk apron or the public right-of-way, and HOA or commercial lots may need their own permitting depending on scope. A contractor who pulls permits routinely in the South Bay should be able to tell you upfront whether your job needs one and roughly what it adds, rather than leaving you to find out from the city after the fact.
A number by itself doesn't tell you much. A quote worth trusting should spell out the asphalt thickness in inches, what's happening to the base (nothing, patched, or fully rebuilt), the total square footage being paved, drainage or grading work if it applies, and a timeline. If a bid is missing most of that and just lists a total price, ask for the detail before you sign anything. It's a reasonable question, and a contractor who's actually going to do the work has ready answers.

No. Sealcoating protects asphalt that's still structurally sound, but it can't fix a base that's failed, a pothole, or alligator cracking. Putting sealcoat over structural damage just hides the problem for a while and ends up costing you the sealcoat job on top of the eventual repair.
Usually thickness or base work, sometimes both. A low bid may be planning thinner asphalt or skipping base repair that a higher bid includes. Ask both contractors for the same level of detail, thickness in inches and what's happening to the base, before assuming one is simply overcharging.
Roughly, yes, since material and labor scale with square footage, but a long driveway on a slope can cost more than a short flat one of the same size because of the extra drainage and grading work a grade requires.
Patching a small, contained problem now is almost always cheaper than letting it spread. Alligator cracking or a pothole left alone tends to grow, and by the time it's bad enough to force a repave, you've often paid for a patch that didn't hold and the repave both.
The per-square-foot number is often lower on a large lot because mobilization costs spread across more area, but total project cost is naturally higher, and commercial jobs usually add striping, ADA-compliant stall layout, and phasing around tenants, none of which a driveway needs.
