Subcontractor Default Insurance (SDI) for Production Builders
Subcontractor default insurance (SDI) is a first-party policy that reimburses a production builder for the added cost of completing a subcontractor's work when that sub defaults — financially fails, walks off the job, or performs so poorly the work must be redone — an alternative or complement to requiring individual performance bonds from every subcontractor.
Subcontractor default insurance protects the builder directly, as a first-party policy, against the financial impact of a subcontractor default — the sub going out of business mid-project, walking off the job, or performing work so poorly it has to be redone by someone else. It's distinct from general liability, which responds to third-party injury or property damage claims, and it's structured very differently from a traditional performance bond, even though both address a version of the same underlying worry: a subcontractor failing to finish what they started.
For a production builder running dozens of active homes across multiple phases with the same core group of subcontractors doing the same trade work repeatedly, subcontractor default risk isn't a rare event — it's a recurring operational reality. A framing crew that overextends itself across too many concurrent phases, a specialty trade that underbids and can't sustain the workload, or a sub whose finances quietly deteriorate over a multi-year development timeline can each create real completion-cost exposure, and doing it across a hundred homes with a hundred individual performance bonds is administratively heavy.
Contractors Choice Agency helps production builders evaluate whether an SDI program — one annual policy covering subcontractor default risk across their active portfolio — makes more sense than managing bonds subcontractor-by-subcontractor, based on their roster size, prequalification practices, and typical project volume.

What's covered
- Reimbursement for the increased cost of completing a defaulted subcontractor's scope of work with a replacement crew
- Coverage across your active subcontractor roster under one annual policy, rather than a bond purchased project-by-project
- Builder retains more control over default determination and remediation timing compared to a traditional bond claim process
- Can reduce the administrative load of collecting and tracking individual performance bonds from every subcontractor on every phase
- Encourages — and in most SDI programs requires — stronger subcontractor prequalification practices, which reduces default frequency over time
- Coverage designed to scale with a rotating roster across multiple concurrent phases, matching how production builders actually staff developments
Ideal for builders that…
- Production builders managing a large, rotating roster of subcontractors across multiple concurrent phases
- Builders who currently require individual performance bonds from every subcontractor and want to evaluate a more centralized alternative
- Companies with formal subcontractor prequalification processes already in place, or willing to build one as part of an SDI program
- Builders who have experienced a subcontractor default and want a more predictable, faster path to completing the affected work
- Developments large enough that a single subcontractor default could meaningfully affect schedule and cost across multiple homes at once
SDI versus performance bonds: two different risk-transfer tools
A performance bond is a three-party agreement between the builder, the subcontractor, and a surety, where the surety guarantees the subcontractor's performance and steps in — often through a somewhat structured claims process — if the sub defaults. Subcontractor default insurance is a two-party arrangement between the builder and the insurer, generally giving the builder more direct control over declaring a default, selecting a replacement, and moving quickly to keep the schedule intact, without waiting on a separate surety's own investigation and remediation process.
Neither tool is universally better — some production builders use SDI for their core roster and still require bonds on specific high-value or higher-risk trade packages. The right mix depends on your subcontractor base, project volume, and how much control you want over the default-and-cure process versus how much you want to transfer to a third-party surety.
Why SDI fits a production builder's roster better than bond-by-bond management
Requiring a performance bond from every subcontractor on every phase means managing dozens or hundreds of individual bond relationships, each with its own paperwork, renewal, and claims process — a significant administrative load at production-builder volume, and one that scales linearly with how many homes and phases you're running.
An SDI program instead covers subcontractor default risk across your active roster under one annual policy, which scales more naturally with a production builder's actual operating model: a relatively stable core group of subcontractors working repeatedly across many homes and phases, rather than a new one-off relationship for every individual project.
- One annual SDI policy versus dozens or hundreds of individual bond relationships to track
- Faster, builder-controlled default determination and remediation compared to a typical bond claims process
- Strong subcontractor prequalification — financial, operational, and performance vetting — is generally required, which also improves overall subcontractor quality
Prequalification: the foundation SDI is built on
SDI carriers generally expect a documented subcontractor prequalification process before extending coverage — financial statements, bonding capacity or history, safety record, and past performance are typical inputs. This isn't just an underwriting hurdle; a disciplined prequalification process is also the single biggest lever a production builder has for reducing default frequency in the first place, independent of what insurance program sits behind it.
We help production builders evaluate their current subcontractor vetting practices as part of setting up an SDI program, since the strength of that process directly affects both what coverage terms are available and how often the coverage actually gets used.
What determines the cost of this coverage
Every production builder is different. Here's what typically moves the price of this coverage up or down.
Total enrolled subcontractor payroll or contract value
SDI is typically rated against the volume of subcontracted work enrolled under the program across your active portfolio.
Subcontractor prequalification rigor
A documented, disciplined prequalification process — financial, operational, and performance vetting — meaningfully affects available terms and pricing.
Historical default frequency
A builder's own track record of subcontractor defaults, and how quickly they were resolved, is a direct pricing factor at renewal.
Trade mix and concentration
Reliance on a small number of subcontractors for critical-path trades concentrates default risk differently than a broad, diversified subcontractor base.
Number of concurrent active phases
More concurrent phases increase the number of active subcontractor relationships enrolled under the program at any given time.
FAQs about Subcontractor Default Insurance
No — a performance bond is a three-party surety arrangement between the builder, subcontractor, and a bonding company. SDI is a two-party, first-party insurance policy between the builder and an insurer, generally giving the builder more direct control over how a default is declared and remediated.
Not necessarily for your full roster — many production builders use SDI to cover their core, recurring subcontractor base and reserve individual bonds for specific high-value or higher-risk trade packages outside the SDI program. The right mix depends on your subcontractor base and risk tolerance.
Typical triggers include the subcontractor failing to perform, going out of business or becoming financially unable to complete the work, walking off the job, or performing work so deficiently it must be substantially redone — specific trigger definitions vary by policy, which is why reviewing the policy language against your actual subcontract terms matters.
Generally yes — SDI carriers typically expect a documented subcontractor prequalification process covering financial condition, past performance, and operational capacity before extending coverage, since prequalification is one of the strongest levers for reducing default frequency in the first place.
Because the builder generally retains more control over default determination and remediation timing than under a traditional bond claim, SDI programs are often designed to get a replacement crew in place faster — which matters on a production schedule where one delayed home can ripple into a whole phase's completion timeline.
