General liability and workers’ compensation at the limits your contract or owner requires, plus auto liability when the sub drives to site. Many GCs also ask for additional insured, waiver of subrogation, and primary & non-contributory endorsements.
W-9
For 1099 reporting before the first payment.
Safety program and training
Heat illness prevention and equipment safety are reasonable asks, especially on summer jobs.
Trade license
Some states license landscape or irrigation contractors. Licensing rules are set by each state, and sometimes by the county or city, so check what applies where the job is.
References and past projects
Often requested for larger or commercial jobs, or before a first job with a new sub.
Bonding
On public or bonded jobs, a bonding capacity letter and performance and payment bonds may be required, as the contract specifies.
Requirements vary by state, locality, owner and contract. This is a general starting point, not legal or insurance advice. Your contract and local rules decide what’s actually required.
Questions to resolve before review
Auto liability matters: landscaping crews drive trucks and trailers to and between sites.
If the scope includes digging for irrigation or hardscape, ask how utilities will be located before work starts.
How SubSignoff supports the workflow
Create the project and pick a job type (residential remodel, new home, light commercial, commercial, or public/bonded). SubSignoff suggests editable starting requirements for that job type, such as insurance types, limits, endorsements, W-9 and license.
Add Landscaping as a trade on the job. The job-type requirements apply; add any extra documents you want for this trade. Everything stays editable.
Send the sub a portal link. The sub, or their insurance broker, uploads documents from a phone or computer without creating an account.
Review and track. Check each document against the project’s requirements, record your decision, and send reminders before recorded expiration dates.
SubSignoff records what documents say and whether they meet the requirements you set. It doesn’t confirm coverage with insurers or verify licenses with the state. Check licenses with the issuing agency; for some states SubSignoff links to the official lookup page.
