Contractor Insurance Requirements by Project Type: Residential, Commercial, and Public Work

If you do residential remodels on Monday and commercial tenant buildouts on Friday, you already know the two worlds operate differently. The homeowner signing a kitchen renovation contract has no compliance desk. The commercial GC has one, it's probably running automated certificate tracking software, and it will flag anything that doesn't match the spec.

Move into public work — municipal projects, TxDOT contracts, school district jobs — and the requirements escalate again. Performance bonds, prevailing wage certifications, specific endorsement forms, agency-specific insurance requirements that don't exist in the private sector. A policy built for residential work won't touch a public works contract.

This guide breaks down the insurance requirement stack for each project type. Use it to understand what your current program covers, what you'd need to add to move into a new market, and where to focus your compliance conversations with your broker.

Residential Projects

Residential work — new construction, renovation, repair, and specialty trade work in homes and small multifamily buildings — has the fewest formal insurance requirements of any project type. Most homeowners don't specify coverage limits in their contracts. Most don't verify certificates at all. But that doesn't mean residential contractors don't need robust coverage.

What you actually need (regardless of what the homeowner asks for)

• General Liability: $1 million per occurrence / $2 million aggregate is the standard minimum. Even if the homeowner doesn't ask for it, the exposure is real. Water damage from a plumbing error, a fire from improper electrical work, property damage from a falling ladder — these claims happen on residential jobs and are expensive.
• Workers' Compensation: Texas does not require private employers to carry workers' comp — but if you have employees working on residential projects and one gets hurt, you face the full lawsuit exposure of a non-subscriber. Many residential contractors carry WC to avoid that risk, even though it's not mandated.
• Commercial Auto: Personal auto policies exclude business use. If your crew drives company vehicles or employees use personal vehicles for work and have an accident en route to a job, you need commercial auto or hired/non-owned auto coverage.

The "no license required" trap in residential Texas work

Texas has no general contractor license at the state level. Many trades (painting, drywall, flooring, demo) also have no licensing requirement. This creates a situation where residential contractors operate without the licensing infrastructure that would otherwise enforce minimum insurance standards. The market disciplines this somewhat — homeowners who do their homework verify coverage, and insurance requirements often appear in HOA or community standards for larger neighborhood projects — but plenty of residential work happens without any insurance verification at all.

This is actually a competitive advantage for contractors who do carry proper coverage: you can provide certificates when residential customers ask, and many will ask.

Texas homebuilder-specific requirements

New residential construction has more defined requirements than renovation. Large homebuilders in Texas — national tract builders, regional custom builders — typically require their subcontractors to carry:

• GL at $1M/$2M with the builder named as additional insured (AI) for both ongoing and completed operations
• Waiver of subrogation in favor of the builder
• Workers' comp or acceptable alternative (some builders accept occupational accident policies for non-subscribers)
• Commercial auto at $1M CSL

The compliance rigor varies by builder. National production builders (D.R. Horton, Lennar, Pulte) run sophisticated compliance programs nearly equivalent to commercial GC standards. Smaller custom builders may require similar coverage but verify less strictly.

Commercial Projects

Commercial work — office buildings, retail, industrial facilities, multifamily over a certain unit count, healthcare, hospitality — has the most standardized insurance requirement structure of any project type in the private sector. Commercial GCs run compliance programs, and the expectations are consistent across the market.

The additional insured endorsement matters — the form matters more

On commercial projects, "additional insured" isn't sufficient. The GC and project owner need to be named as additional insureds on the correct ISO form (or equivalent) and for the correct scope of work. The two forms contractors encounter most often:

• CG 20 10: Additional insured for ongoing operations — covers claims arising from work in progress
• CG 20 37: Additional insured for completed operations — covers claims arising after the work is finished

Many commercial contracts require both. If your certificate only lists CG 20 10, the GC's compliance system will flag it as non-compliant for completed operations. The fix is usually adding CG 20 37 by endorsement — but it requires your carrier to issue it, not just noting it on the certificate.

Project-specific vs. blanket endorsements

Blanket additional insured endorsements (ISO CG 20 33) automatically extend AI status to any entity that requires it by written contract. This is more efficient than scheduling each GC individually — you don't need a new endorsement for every project. But blanket forms have a condition: there must be a written contract requiring the AI status before the work begins. Verbal agreements don't trigger blanket coverage. Understand what you have on your policy before you rely on it.

Public Work (Municipal, State, Federal)

Public work is the most demanding insurance environment for Texas contractors. Government entities — cities, counties, TxDOT, school districts, hospital districts, UT System — have their own procurement requirements that go beyond anything in the private sector. The requirements are written into the bid specification document and are non-negotiable.

What changes on public projects

• Higher GL limits: Municipal projects routinely require $2M per occurrence / $4M or $5M aggregate. TxDOT highway contracts may require $5M or more. You'll need umbrella or excess coverage to reach these limits.
• Government entity as additional insured: The City of Austin, TxDOT, the school district — whichever entity is the project owner must be named as additional insured. Government entities are often sensitive to the specific legal name on the certificate (using "City of Austin" when the contract says "City of Austin, Texas" can trigger rejection).
• Performance and payment bonds: Almost all public works contracts above a certain dollar threshold require performance and payment bonds. In Texas, the threshold under the Government Code is $50,000 for certain agencies, but practical experience shows that bonds are required on most public projects above $25,000. Bonds are not insurance — they're financial guarantees. You need a separate surety relationship to obtain them. See our Texas surety bonds guide for the full explanation.
• Prevailing wage compliance: Many Texas public projects are subject to the Texas Prevailing Wage Act. While this is a wage requirement, not an insurance requirement, it interacts with your workers' comp audit because payroll must match wage records. Non-compliance creates both a wage penalty and a potential workers' comp audit adjustment.
• Occupational licenses verified: For state-licensed trades (TDLR-licensed electricians, TSBPE-licensed plumbers), public project specifications often require verification of the license numbers of the supervising licensees.

TxDOT-specific requirements

TxDOT contracts have their own insurance specifications — separate from what a municipality might require. TxDOT typically requires:

• Commercial General Liability: $1M per occurrence minimum (projects above certain value tiers require $2M)
• Business Auto Liability: $1M CSL
• Workers' Compensation: Statutory; employer's liability at $1M/$1M/$1M
• Umbrella: Required for larger projects, with limits specified in the bid package
• The State of Texas named as additional insured and certificate holder
• Endorsements: Waiver of subrogation in favor of the State; primary & noncontributory

TxDOT's insurance requirements are specified in the contract and are non-negotiable. Submitting a certificate that doesn't meet the spec is grounds for rejection of your bid or contract termination. The time to review TxDOT's requirements is before you price the work — because the required limits and any required umbrella coverage affect your insurance costs, which should be factored into your bid.

School district and municipal requirements vary

Unlike TxDOT's standardized specs, municipal and school district requirements vary considerably. The City of Houston uses different limit requirements than the City of San Antonio. A large urban school district will have different requirements than a smaller rural ISDs. Always request the specific insurance section from the bid documents and compare them to your current policy before you submit a bid response.

Specialty: Wrap-Up Programs (OCIP and CCIP)

On large construction projects — typically over $50 million in construction value — the project owner or GC sometimes purchases a wrap-up insurance program (OCIP or CCIP) that covers all enrolled contractors under a single policy. This changes the compliance picture significantly.

If you're enrolled in a wrap-up:

• Your own GL is covered by the wrap for on-site work
• You still need your own GL for off-site work and for the bid credit period before enrollment
• You still need commercial auto, workers' comp (wrap-ups rarely cover WC), and equipment coverage
• You typically receive a bid credit — a reduction in your bid price to account for the fact that the project owner is covering your GL premium for on-site work

The compliance mistake contractors make on wrap-ups: dropping their own GL entirely when enrolled, forgetting they still have exposure on off-site fabrication and materials staging, or failing to properly segregate payroll and receipts between wrap and non-wrap work at audit. For a detailed treatment, see our guide to OCIP/CCIP enrollment for subcontractors.

Comparing the Three Stacks Side by Side

What to Ask Your Broker

1. Does my current GL policy include both CG 20 10 (ongoing) and CG 20 37 (completed operations) additional insured endorsements? Both are required by most commercial and public contracts. Confirm the forms are on the policy, not just noted on the certificate.
2. Does my blanket AI endorsement require a written contract to trigger? If so, make sure every project has a signed subcontract before work begins — verbal agreements won't activate blanket coverage.
3. If I want to bid public work, what limits do I need and what would umbrella coverage cost? Get a quote for a $2M or $5M umbrella so you know the cost before you price the bid.
4. Do I have access to bonding, and if so what's my current bonding capacity? Public work requires bonds. If you don't have a surety relationship, start the conversation early — bonding capacity takes time to build.
5. Can you produce a certificate within 15 minutes that satisfies a commercial GC's compliance system? If your broker needs two days, you'll have compliance problems on fast-moving commercial projects.
