California’s $25,000 Contractor Bond: Why It Won’t Protect You (2026)

The California contractor bond is $25,000. It has been $25,000 since 2016. On a $200,000 ADU contract, that bond represents 12.5% of the project cost — and you do not get all of it. The bond is shared among every claimant who files against that contractor, across every project they have ever worked on. When Anchored Tiny Homes filed Chapter 7 with $12.8 million in liabilities across 450+ homeowners, the bond payout per claimant was a fraction of their losses. The California contractor bond for ADU projects is not insurance. It is a licensing requirement that protects the state’s contractor fund, and the gap between what homeowners assume it covers and what it actually pays is the subject of active legislation.

California requires every licensed contractor to maintain a $25,000 surety bond under Business and Professions Code Section 7071.6. That $25,000 is the total bond. Not per project. Not per homeowner. Total.

When a contractor fails, every affected homeowner files a claim against the same $25,000. The surety company divides whatever’s available among all claimants.

Company	Victims	Bond	Per Person	Avg Loss
Anchored Tiny Homes	55 claims	$25,000	$455	$30,000–$100,000
Multitaskr	100+ claims	$25,000	~$250	$200,000+
Nonna ADU	23 claims	$25,000	$1,087	$83,000–$193,000

$455 against a $100,000 loss. $250 against a $200,000 loss. The bond exists. It pays out. It pays out almost nothing.

A contractor’s surety bond is not insurance. It’s a guarantee — backed by a surety company — that the contractor will follow California contractor licensing law. If the contractor violates the law (takes excessive deposits, abandons a project, performs without a license), affected parties can file a claim against the bond.

The bond covers:

• Violations of the Contractors State License Law
• Failure to pay subcontractors or material suppliers
• Excessive deposit collection beyond the $1,000 / 10% legal limit
• Abandonment of contracted work
• Unlicensed activity by the contractor’s employees

The bond does NOT cover:

• The full cost of your project if the contractor disappears
• Your deposit beyond what the bond pool allows per claimant
• Legal fees to pursue the claim
• Emotional distress or consequential damages
• The cost of hiring a second contractor to finish the job

The bond is a penalty mechanism, not a recovery mechanism. It penalizes the contractor (their bond gets paid out and they must post a new one). It does not make the homeowner whole.

Most homeowners hear “bonded and insured” and assume they’re protected. They picture something like car insurance — if the contractor wrecks the project, the bond pays to fix it. That’s wrong in every way that matters.

The bond is $25,000. Your ADU costs $250,000. The bond covers 10% of one project — if you’re the only claimant. Add other victims and your share drops to hundreds of dollars. On a six-figure loss.

NBC Bay Area’s investigation interviewed homeowners who discovered this gap after Anchored Tiny Homes collapsed. They’d checked the license. They’d confirmed the bond was active. They assumed the bond meant they were covered. The bond was active. It paid $455 per person.

The phrase “bonded and insured” on a contractor’s website is technically true and practically meaningless for consumer protection at scale. For a detailed explanation of how bonds work mechanically, see our surety bond guide.

The $25,000 bond amount was last updated in 2007. Since then:

• Average ADU construction costs have increased from ~$80,000 to $200,000-$400,000
• California home prices have roughly doubled
• Construction material costs have increased 40-60%
• The ADU market has exploded — California issued more ADU permits in the last 3 years than the previous 20 combined

The bond was never designed for the ADU market. In 2007, most residential contractor failures involved single projects — one homeowner, one claim, one bond. A $25,000 bond on a $100,000 kitchen remodel covered 25% of the loss. Not great, but meaningful.

In 2026, ADU contractors sign dozens or hundreds of contracts simultaneously. Multitaskr signed 100+ contracts. Anchored signed 450+. When these companies collapsed, the $25,000 bond that was designed for one-off failures was shared across hundreds of victims. The bond didn’t change. The scale of failure did.

Anchored Tiny Homes (Sacramento): Filed Chapter 7 bankruptcy with $12.8 million in liabilities against $1.2 million in assets. 450+ homeowners abandoned. CSLB received 55 formal complaints. Bond: $25,000. Per-person bond recovery: $455. Individual losses: $30,000-$100,000 each. Both CEO Colton Paulhus and co-founder Austin Paulhus filed personal bankruptcy.

Multitaskr (Chula Vista): Took at least $15 million from 100+ homeowners. Arranged construction loans under homeowners’ names for ADUs that were never built. CEO Jose Frausto filed personal bankruptcy with $3.9 million in liabilities. CSLB revoked the license and banned four corporate officers. Bond: $25,000. Average individual loss: $200,000+.

Nonna ADU (Sacramento): 23 CSLB complaints, 8 referred to the Attorney General. One family paid $193,706 with zero work performed. CSLB filed an accusation to revoke. Bond: $25,000. President Ray Guanill began promoting an unregistered new company. Per-person bond recovery: $1,087.

Next Generation Builders (LA): Found clients on Instagram. One homeowner paid $200,000 for an abandoned two-story ADU. Another paid $84,000 for a skeleton frame. CSLB complaints were hidden until NBC Los Angeles investigated. Bond had expired before the license was suspended.

Assemblymember Marc Berman introduced AB 559 in February 2025, sponsored by CSLB. The bill toughens penalties for ADU contractors who violate deposit limits. It does not increase the bond amount.

AB 559 addresses how contractors collect money — limiting upfront payments and adding penalties for violations. That’s a real improvement. But it doesn’t fix the recovery gap. When a contractor takes your money and files bankruptcy, the penalty for violating deposit rules doesn’t put money back in your account. The bond still does that — and the bond is still $25,000.

Increasing the bond amount has been discussed in Sacramento for years. As of 2026, it remains at $25,000. The construction industry lobbies against increases because higher bonds mean higher costs for contractors. Homeowners don’t have a comparable lobby.

The bond won’t cover your loss. What will:

1. The $1,000 / 10% deposit cap. California law limits your initial deposit to $1,000 or 10% of the contract, whichever is less. On a $250,000 ADU, your maximum legal deposit is $1,000. If you lose that, you lose $1,000 — not $80,000. Every homeowner in the Anchored, Multitaskr, Nonna, and Next Gen cases paid far more than the legal limit. The law already protects you — if you follow it. Full license verification guide here.
2. Milestone-based payments. After the deposit, pay only for completed and inspected work. Foundation passes inspection — pay for foundation. Framing passes — pay for framing. Never pay ahead of verified progress. A contractor who disappears after the foundation phase costs you 20% of the project, not 100%.
3. Your own due diligence. CSLB license check, BBB complaints, Google/Yelp reviews, web search for “[contractor] scam,” county court records. Thirty minutes of checking catches what the bond can’t fix after the fact. CSLB doesn’t show all complaints — check multiple sources.
4. A verified directory. Every builder in our Sacramento, Los Angeles, San Diego, and SF Bay Area directories has been checked for active license, current bond, workers’ comp, complaint history, and ADU-specific track record. The bond alone is a checkbox. We check what the bond can’t tell you.

How much is a contractor’s bond in California?

$25,000. This is the state minimum under Business and Professions Code Section 7071.6. It’s the total bond amount — shared across all claimants, not per homeowner. The amount hasn’t been updated since 2007.

Does the contractor bond cover my full ADU project cost?

No. ADU projects cost $150,000-$400,000. The bond is $25,000 total, split among all victims. If 50 homeowners file claims, each gets roughly $500. The bond is a penalty mechanism, not an insurance policy.

What’s the difference between a contractor bond and insurance?

Insurance covers losses up to the policy limit per incident. A bond is a shared pool — $25,000 total divided among all claimants. Insurance pays you back. A bond splits a small amount among everyone who got hurt. For ADU-scale projects, the bond recovers a fraction of a percent of most losses.

Has the $25,000 bond always been the requirement?

The current amount was set in 2007. Before that it was lower. California legislators have discussed increasing it but the amount remains unchanged as of 2026. ADU construction costs have increased 200-400% since 2007 while the bond stayed flat.

How do I file a claim against a contractor’s bond?

Contact the surety company listed on the contractor’s CSLB license detail page. File a written claim describing the violation. The surety investigates and pays valid claims from the $25,000 bond pool. If multiple homeowners file, the surety divides the bond among all valid claims. The process takes months. For a full walkthrough, see our surety bond guide.

Will AB 559 increase the contractor bond?

No. AB 559 toughens penalties for ADU contractors who violate deposit limits. It does not increase the $25,000 bond amount. The bond increase has been discussed in the California legislature but has not advanced due to industry opposition.

What protects me more than the bond?

The $1,000/10% deposit cap (California law — follow it), milestone-based payments tied to inspections, CSLB license verification, BBB/Yelp/Google review checks, and using a verified directory that screens for ADU-specific track record. Prevention beats recovery. The bond pays pennies after a loss. Due diligence prevents the loss.

Should I still check if a contractor is bonded?

Yes — an active bond is required by law and its absence means the license should be suspended. Check at cslb.ca.gov. But don’t treat “bonded” as proof of safety. It means the contractor paid a surety company a small premium to maintain the bond. It does not mean $25,000 is sitting in an account waiting to cover your project if something goes wrong.
