Complete quote
Written quote in 24–48 hours. Detailed scope, specifications, exclusions, warranty, and "everything included" total — nothing hidden, no line-item renegotiation.
Contract + $1,000 deposit
§7159-compliant written contract. $1,000 OR 10% — whichever is LESS — locks your pour date. This is the max anticipo allowed under California Business & Professions Code §7159.5(a)(3). Progress payments tied to work completed — never upfront.
Clean pour, clean exit
Crew works tight and clean. Forms stripped, joints cut, site swept. Final walkthrough before we leave.
The permit fee myth.
Some contractors quote you extra for "pulling the permit" on your driveway. For most residential work in Solano County, that permit doesn't even exist.
CBC §105.2(6)
California Building Code exempts sidewalks and driveways at grade level (under 30" above adjacent grade, not part of an accessible route) from building permit requirements — statewide.
Every Solano city
Fairfield, Vacaville, Napa, Vallejo, Benicia, Suisun City, Dixon, American Canyon, Rio Vista — they all follow California §105.2. Same exemption everywhere.
C-8 Concrete License
CSLB #1074044. The state already licensed us to perform this work. Our specs — 6-sack 4000 PSI, #3 rebar, proper base — meet or exceed code.
When permits ARE required (rare):
- Public right-of-way work — curb cuts, sidewalk in the ROW — may need an encroachment permit from Public Works
- Walls retaining more than 4 ft of soil — engineered permit required
- Accessible-route work — ADA compliance projects
- Commercial or publicly-funded projects — different rules apply
In those cases, the property owner or general contractor verifies and obtains the permit. We perform the work under our C-8 license and flag these requirements during the free site visit.

Four payments. Every one tied to work completed.
California caps down payments at the LESSER of 10% or $1,000 per §7159.5(a)(3). On most residential jobs, this means $1,000. On smaller jobs (under $10,000), it means 10%. Either way — never more. Contractors asking for 30-50% upfront are violating state law — here's how to know.
Contract signed, pour date locked. Max: $1,000 OR 10% (lesser) per §7159.5(a)(3).
Demo, base, forms, rebar physically in place.
6-sack 4000 PSI placed & finished.
After walkthrough + lien release §7159(c)(4).
🚨 Red flags in other contractor quotes
- "30-50% deposit required" — violates §7159.5(a)(3). Max is $1,000 or 10%, whichever is LESS.
- "Pay when done, no contract" — violates §7159(d). Written contract required for $500+ home improvement.
- "I'm solo, no workers comp" — C-8 class MUST carry WC regardless (CSLB Title 16 Div 8).
- Missing 12-point §7159 warning in contract — legally defective document.
- "Permit fee: $300" on residential driveway — CBC §105.2 usually exempts it. Possible fraud.
Your legal remedy if a contractor violates §7159: you may be entitled to recover all payments under §7031. We follow the law so you never need to use it.
⚖️ CALIFORNIA §7159 MANDATORY WARNING
"IT IS AGAINST THE LAW FOR A CONTRACTOR TO COLLECT PAYMENT FOR WORK NOT YET COMPLETED, OR FOR MATERIALS NOT YET DELIVERED. HOWEVER, A CONTRACTOR MAY REQUIRE A DOWNPAYMENT."
This 12-point boldface warning is required in every California home improvement contract over $500. Every Bachi contract includes it. If a contractor's contract doesn't — that's a §7159 violation.
