San Jose Contractor BondBuilt for the ADU & Remodel Boom

San José issued 488 ADU building permits in 2024 — up from just 10 in 2015, per the City's own permitting data. That volume is why more San Jose contractors are hitting a second bonding question mid-project: their $25,000 CSLB license bond under Business and Professions Code Section 7071.6 gets them licensed, but the sewer lateral, driveway approach, or sidewalk work an ADU often needs runs straight into a separate San Jose Public Works permit.

Why San Jose's ADU Boom Is Also a Bonding Story

The City of San José's own permitting data shows building permits for accessory dwelling units grew nearly 49-fold in nine years — 10 permits in 2015 to 488 in 2024. The units themselves have also gotten bigger: in 2015 only 6% of permitted ADUs exceeded 700 square feet; today more than a third qualify as "large" ADUs. For a Class B general building contractor or a C-36 plumbing sub, that shift matters because larger ADUs and full-scope kitchen or bath remodels are far more likely to need a new sewer lateral, an upsized water service, or a widened driveway approach — and any of those touches the public right-of-way, which is where San Jose's bonding picture stops being a single-layer CSLB question.

Every one of those contractors already carries the statewide $25,000 CSLB license bond required to hold a license at all. What the ADU and remodel wave adds is a second, project-specific filing at San Jose Public Works whenever the scope crosses onto city property. A contractor who only ever remodels interiors may never see this second layer. A contractor building backyard ADUs full-time in San Jose almost certainly will, on a meaningful share of jobs.

Layer 2 — City Permit Security

San Jose Municipal Code 13.36 & 13.37: The Right-of-Way Trigger

San José Public Works administers two Title 13 chapters that govern work touching the public right-of-way: Chapter 13.36, "Public Right-of-Way Work Permits," and Chapter 13.37, "Encroachment Permits." The City's own encroachment-permits page confirms both chapters as the governing authority and states plainly that these permits "typically require a plan showing the work proposed, as well as fees and a security deposit." That security deposit is the piece contractors miss when they assume their CSLB bond already covers city-permitted work — it does not. The two obligations run to different obligees: the CSLB bond protects consumers and the state; the SJMC security protects the City against damage to public infrastructure and unfinished restoration.

For ADU and remodel contractors specifically, the most common triggers are a new or modified sewer lateral connection, a driveway approach cut into the curb, sidewalk replacement where a walkway is damaged during construction, and any excavation within the street right-of-way for a new water or gas service line. None of those are unusual on a backyard ADU build — they are close to routine.

Hedge note — Neither SJMC Chapter 13.36 nor 13.37 fixes a single dollar amount for the permit security in the way BPC 7071.6 fixes the CSLB bond at $25,000. San Jose Public Works Development Services (200 E. Santa Clara St., (408) 535-3555) sets the fee and security deposit per permit application based on the scope of right-of-way work. Confirm the exact figure before you bid rather than relying on a flat estimate.

Layer 1 — Statewide License Bond

The $25,000 CSLB Bond Underneath Every San Jose Job

Regardless of what a San Jose project needs at the city level, the floor is always the same: a $25,000 contractor license bond under BPC § 7071.6, filed with the Contractors State License Board, required of every Class A, Class B, or Class C licensee before CSLB will issue, renew, or reactivate a license. Senate Bill 607 raised this from $15,000 to $25,000 effective January 1, 2023. If you operate as an LLC, add the $100,000 employee/worker bond under BPC § 7071.6.5 — $125,000 in total statewide bonding before a single San Jose permit is even pulled. Full detail on both bonds lives on our California CSLB bond hub and the dedicated CSLB bond statute page.

As of January 1, 2025, Assembly Bill 2622 raised the handyperson exemption from $500 to $1,000 in combined labor and materials — but that exemption never applies to work requiring a building permit, which covers essentially every ADU and most remodels. In practice, if a San Jose homeowner is pulling a permit for the job, the contractor doing the work needs the license and the bond.

A Third Reality — Corporate Campus Work

Subcontracting on North San Jose's Tech Campuses Is a Different Bonding Conversation

Residential ADU and remodel work is only one side of the San Jose construction market. The other is the corporate campus pipeline — most visibly Google's Downtown West development, which the City of San José approved for up to 7.3 million square feet of office space and up to 5,900 housing units across roughly 80 acres of the 250-acre Diridon Station Area. That is a privately owned project. The City is the land-use approving authority, not the owner requiring contract surety, so the statutory payment-bond mandate in California's Public Contract Code — which governs true public works — does not automatically apply here the way it would on a City-owned building.

What replaces the statutory requirement is the general contractor's own prequalification bar. A GC building out a private corporate campus almost always requires subs to show an active $25,000 CSLB bond in good standing as a baseline, and on larger scopes will contractually require a performance and payment bond sized to the subcontract value — not because state law demands it on private work, but because the GC's own contract terms do. Compare that against a genuinely public San Jose project — a library, a VTA station, a San José Unified school — where California's "Little Miller Act" (Public Contract Code §§ 7100-7107) does mandate a 100% payment bond and typically a matching performance bond, set by the awarding agency rather than a GC's internal policy. Same city, same $25,000 CSLB floor, two very different paths to the contract surety that sits on top of it. See performance and payment bonds and California performance bonds for how that underwriting differs from the license bond.

What San Jose Contractors Actually Pay

CSLB bond premium by credit tier — the Public Works security is priced separately, per permit

The Public Works right-of-way security is not credit-priced the way the CSLB bond is — it is a fee-plus-deposit set by scope of work at permit application. Budget for it as a project cost tied to the specific sewer-lateral, driveway, or sidewalk scope, not as an annual premium. Our contractor license bond calculator estimates the CSLB layer only.

San Jose Contractor Bond FAQs — ADU, Permits & Tech Campus Work

Six questions specific to how San Jose actually bonds its residential and commercial construction.

Does my $25,000 CSLB bond cover a San Jose ADU project, or do I need something extra?
The $25,000 CSLB bond under Business and Professions Code Section 7071.6 covers you as a licensed contractor on any San Jose project regardless of type — that part never changes for an ADU. What it does not cover is the separate city-layer security that San Jose's Public Works Development Services Division requires when the ADU's utility connections touch the public right-of-way. A detached ADU almost always needs a new or upsized sewer lateral, a water service, or a driveway approach, and each of those triggers a Public Right-of-Way Work Permit or Encroachment Permit under San Jose Municipal Code Chapters 13.36 and 13.37 — which carries its own fee and security deposit, filed at Public Works, separate from your CSLB bond. See our /contractor-license-bonds/california/ page for the statewide layer in full.
What San Jose permits actually require the city-layer security deposit — is it every ADU?
No. San Jose's ADU Universal Checklist streamlines the building-permit side of ADU review, but the right-of-way security is triggered by the scope of work touching public property, not by the fact that it is an ADU. A backyard ADU that ties into existing utility stubs with no street, sidewalk, or driveway disturbance typically does not need an encroachment permit. A conversion that requires a new sewer lateral tap, a widened driveway approach, or sidewalk replacement does. Confirm the trigger with San Jose Public Works Development Services (200 E. Santa Clara St.) before you bid, because the security amount is set per permit rather than by a fixed schedule in the code.
How much is the San Jose encroachment permit security compared to the CSLB bond?
They are priced completely differently. The CSLB bond is a fixed $25,000 face amount with an annual premium — typically $125 to $1,000 a year for a licensed contractor with average-to-excellent credit. The San Jose Public Works security under SJMC 13.36/13.37 is not a fixed-amount annual bond; it is a fee-plus-security-deposit set per permit application, sized to the scope of the right-of-way work. Most sewer-lateral and driveway-approach jobs on a residential remodel or ADU fall in a modest range, but Public Works sets the exact figure when you apply — always confirm on the permit application, not from a generic online estimate.
Can I sub on Google's Downtown West project or another North San Jose tech campus with just my CSLB license bond?
It depends entirely on who you are contracting with, not on the license bond. Downtown West is a privately owned development — the City of San José approved up to 7.3 million square feet of office space and up to 5,900 housing units across roughly 80 acres of the Diridon Station Area, but the City is the land-use approving agency, not the project owner requiring contract surety. Because it is private ownership, the statutory payment-bond mandate in the California Public Contract Code (which applies to public works) does not automatically attach. What does attach is the general contractor's own prequalification requirement: most GCs building for Alphabet, Apple, or other North San Jose corporate campuses will not release a subcontract without evidence of your $25,000 CSLB bond in good standing plus, on larger scopes, a contractually required performance and payment bond sized to your subcontract value. That second bond is not optional just because the project is private — it is a GC contract term, and it underwrites differently than the license bond. See /performance-and-payment-bonds/ for how that underwriting works.
Does bidding a public project in San Jose — a library, a VTA station, a school — change my bonding beyond the CSLB bond?
Yes, and this is the one case where the bond requirement is statutory rather than contractual. Public works let by the City of San José, Santa Clara Valley Transportation Authority, or San José Unified School District fall under California's "Little Miller Act" (Public Contract Code Sections 7100-7107), which mandates a 100% payment bond on any public works contract and typically a matching performance bond required by the awarding agency. Your $25,000 CSLB license bond has nothing to do with qualifying for that contract — the agency requires the contract surety separately, underwritten on your financials rather than credit alone. Compare this against the Downtown West scenario above, where the same statutory mandate does not apply because the owner is private.
Where do I actually file each bond — CSLB, or San Jose Public Works?
Two different filings, two different agencies, and neither substitutes for the other. The $25,000 CSLB license bond is filed electronically with the Contractors State License Board in Sacramento and is what keeps your statewide license active — it has nothing to do with any specific San Jose address. The Public Right-of-Way Work Permit or Encroachment Permit security under SJMC Chapters 13.36/13.37 is filed with San José Public Works, Development Services Division, at the time you apply for the permit for that specific job. CSLB will not accept the city security in place of your license bond, and Public Works will not accept your CSLB certificate in place of the permit security.
