What is SB 800 in California construction?

SB 800, the Right to Repair Act (Civil Code section 895 et seq.), sets statutory building standards for new for-sale homes and gives homeowners up to 10 years after close of escrow to pursue defined construction defects, with a mandatory pre-litigation right-to-repair process for builders.

Why do California residential projects use wrap-up insurance?

Because SB 800 creates a 10-year completed-operations exposure across every sub on the project, and the standard GL market largely excludes new for-sale residential construction. A wrap (OCIP or CCIP) puts the builder and all enrolled subs under one program with a dedicated 10-year completed-ops extension.

Does a subcontractor's own insurance cover residential wrap projects?

Generally no - most subs' GL policies exclude enrolled wrap work, and many exclude for-sale residential work entirely. The sub's own program still covers tools, autos, workers' comp, and off-site or non-wrap work, which is why enrollment status must be confirmed before mobilizing.

How long does wrap coverage last after a residential project finishes?

A properly structured California residential wrap carries a completed-operations extension running the full 10-year SB 800 window from substantial completion or close of escrow. Subs should get the tail confirmed in writing - the post-closeout gap is the most litigated coverage issue in residential defect claims.

SB 800 and Residential Wrap-Ups: Why California Homebuilders Use OCIPs (What Subs Must Know)

By Tamir Lerner, CA License #6012320 · Wrap Insurance CA · Updated August 2026

Quick answer: SB 800 (California's Right to Repair Act, Civil Code §895 et seq.) gives homeowners a statutory 10-year path to claim construction defects on new homes — which is precisely why nearly every sizable California residential project runs on a wrap-up (OCIP/CCIP): it's the only clean way to hold ten years of completed-operations coverage together across dozens of subs. If you're a sub on a residential wrap, your enrollment, your exclusion endorsements, and what happens after closeout matter more than the premium credit.

Ask why residential wraps dominate California homebuilding and you'll get vague answers about "efficiency." The real driver is legal: SB 800 created a defined, decade-long defect liability window, and insurers responded by pulling residential completed-ops coverage from the standard market. The wrap is the workaround that became the standard. Here's how it works and what subs need to verify before signing a residential contract.

What SB 800 actually does

Statutory standards: it defines what counts as a defect (water intrusion, structural, soils, plumbing, electrical...) for new for-sale homes sold after 2003.
The 10-year tail: most claims can be brought up to 10 years after close of escrow (shorter windows apply to specific components).
Pre-litigation process: builders get notice and a right to repair before suit — but the practical effect is a documented pipeline of claims that lands on whoever's insurance is still standing a decade later.

The statute text: California Civil Code, Title 7 (Right to Repair).

Why that produces wraps

Problem SB 800 creates	How the wrap answers it
Ten years of completed-ops exposure per home	One policy with a dedicated 10-year products/completed-ops extension
Dozens of subs with inconsistent, lapsing policies	Everyone insured under one program with uniform limits
Standard-market GL excludes new residential construction	The wrap is purpose-built; subs' own policies exclude wrap work anyway
Cross-suits between builder and subs	Shared program suppresses finger-pointing litigation

What subs must verify on a residential wrap (before bidding)

Your own policy's wrap exclusion. Most subs' GL policies exclude enrolled wrap projects — fine — but confirm whether yours excludes all residential work, enrolled or not. Many do, and an unenrolled townhome punch-list job could be bare.
Enrollment is per-project and not automatic. Complete the enrollment paperwork before mobilizing; showing up unenrolled means your (excluded) policy is all you have. Our checklist: what subs must verify before bidding.
The completed-ops tail. Ask for the wrap's completed-operations extension in writing — it should run the full 10-year SB 800 window. The gap after closeout is the classic residential trap: completed ops and the wrap.
What the wrap doesn't cover. Your tools, your autos, your workers' comp (usually — some wraps include comp, most in CA are GL-only), and your off-site work all stay on your own program.
Bid math. The builder deducts an insurance credit from your price; make sure the deduction matches what you actually save — the mechanics are in how a wrap changes your bid.

The 2026 residential market picture

Builder demand for wraps remains structural — SB 800 didn't sunset and the standard market still avoids for-sale residential completed ops. What's shifted: wrap carriers are scrutinizing sub trades harder at enrollment (waterproofing, framing, and stucco get extra questions), deductibles/SIRs passed down to subs are rising, and builders increasingly require subs to carry their own excess above wrap limits on attached product. Read the insurance exhibit as carefully as the scope.

The bottom line

SB 800 turned every new California home into a ten-year liability, and the wrap is the industry's answer. For subs, the wrap is genuinely good coverage — if you're actually enrolled, the tail actually runs ten years, and your own policy still covers everything the wrap leaves behind. Verify all three in writing, every project.
