San Diego Outdoor Living Subcontractors (2026): How to Verify Licensed Trades, Insurance, and Lien Releases
Updated January 2026 – San Diego County


Most San Diego outdoor living projects include subcontractors. That’s normal and often ideal. The question is not “Do you use subs?” The question is:
- Are the subcontractors licensed for their trade?
- Are they insured (liability + workers’ comp)?
- Are permits and inspections handled correctly?
- Are lien releases managed so the homeowner is protected?
This guide gives you a simple, best-in-class system to vet subcontractors and trade partners on any outdoor living project in San Diego County. It’s written to help homeowners spot “under the hood” risks that sloppy organizations hide.
Educational only (not legal advice). For legal guidance about licensing, insurance, liens, or disputes, consult a California construction attorney.
TL;DR — The Subcontractor Vetting System
- Get a sub list early. Ask your contractor for the major subs and suppliers they plan to use.
- Verify each license on CSLB. Status must be active and classification must match the work.
- Verify insurance for each major trade. Liability + workers’ comp; confirm insured name matches CSLB entity.
- Confirm who pulls permits. Electrical and gas/plumbing permits should be pulled under the correct license (or by the properly licensed sub).
- Keep payment clean. Milestone payments + written change orders only.
- Use lien releases. Conditional before payment, unconditional after funds clear.
- Document everything. Save CSLB screenshots, COIs, endorsements, permit numbers, inspection sign-offs, and releases.
Why Subcontractor Vetting Matters
Outdoor living projects involve high-risk scopes: gas lines, electrical circuits, heavy demolition, retaining walls, and right-of-way work. Many contractors “sell” the project, then quietly hand off critical scopes to whoever is cheapest and available.
When subs are unlicensed or uninsured, homeowners face increased risk:
- Permit problems, failed inspections, or stop-work orders
- Insurance gaps and homeowner liability exposure
- Mechanics lien risk if subs/suppliers aren’t paid
- Warranty disputes with no documentation trail
The 7-Step Subcontractor Vetting System
- Ask for the “Major Trades” list. Electrical, gas/plumbing, concrete/masonry, steel/fabrication, grading/excavation, and any specialty systems.
- Get license numbers for each trade. Do not accept “we have a guy.”
- Run CSLB checks for every major trade. Confirm active status and correct classification.
- Request COIs for each major trade. General liability + workers’ comp (and auto if vehicles are involved).
- Match names. COI “insured” name must match CSLB license entity (exactly).
- Confirm permit responsibility. Electrical and gas/plumbing permits must be pulled under the proper license, with inspection plan identified.
- Protect payments. Milestone payments + lien releases, and joint checks if needed for high-dollar suppliers.
Key Trades in Outdoor Living (What to Verify)
| Trade | Why It Matters | Ask For |
|---|---|---|
| Electrical | Circuits, trenching, bonding/grounding, outdoor outlets, lighting controls, heaters. | C-10 license #, COIs (GL + WC), permit #, inspection plan. |
| Gas / Plumbing | Gas lines for grills/heaters/fire features, shutoffs, pressure tests, appliance tie-ins. | C-36 license #, COIs, gas permit #, pressure test/inspection plan. |
| Concrete / Masonry | Slabs, footings, walls, veneer, structural elements, settlement risk. | License # (C-8/C-29 or appropriate), COIs, engineered details if required. |
| Grading / Excavation | Drainage performance, slope stability, export, underground conflicts. | License # (if contracting), COIs, grading/drainage plan. |
| Steel / Fabrication | Pergola frames, custom railings, structural connections, corrosion issues. | Fabricator COIs, install responsibility, anchorage details, finish specs. |
License Checks: What California Law Actually Allows
In California, there is a “minor work” exemption for very small jobs under specific conditions. As of 2025, the exemption is generally under $1,000, the work must be casual/minor, must not require a permit, and the person cannot employ others. Most outdoor living projects exceed this threshold and involve permits, which means licensed contractors are required.
Use our step-by-step CSLB guide to verify every major trade partner:
Insurance Checks: COIs, Workers’ Comp, and “Name Match” Traps
A subcontractor can be “licensed” and still be a risk if their insurance is missing, expired, or under the wrong entity name.
- COI insured name must match CSLB entity (exact spelling).
- Dates must be current for the work period.
- Workers’ comp must be active for any sub with employees.
- Call the agent on the COI and confirm the policy is active.
- Additional insured claims require endorsements (COI wording alone is not enough).

Permits and Inspections: Which Trade Owns Which Permit?
A common “sloppy contractor” pattern is letting permits slide or pushing them onto the homeowner. A clean system looks like this:
- Prime contractor coordinates permits as part of the project plan.
- Electrical permit is pulled under the electrician’s proper license (or under the entity authorized by the jurisdiction).
- Gas/plumbing permit is pulled under the plumbing/gas contractor’s proper license.
- Inspections are scheduled and documented with sign-offs saved in the project record.

Lien Releases and Joint Checks: How Homeowners Stay Protected
Even if you pay your contractor, subcontractors and suppliers may have lien rights if they are not paid. The clean solution is paperwork discipline:
- Conditional lien releases before payment (progress and final).
- Unconditional releases after payment clears (progress and final).
- Joint checks for high-dollar suppliers or high-risk trades when appropriate.

Email Scripts (Copy/Paste)
Script #1: Request the subcontractor list + license numbers
Hi [Name],
Before we move forward, please send a list of the major subcontractors and suppliers you plan to use (electrical, gas/plumbing, concrete/masonry, etc.), along with their CSLB license numbers. We will verify each one through CSLB and keep it in our project file.
Thank you,
[Your Name]
Script #2: Request COIs + workers’ comp for key subs
Hi [Name],
Please email the general liability and workers’ comp COIs for the key subs that will be on our property (electrical, gas/plumbing, concrete/masonry). Please ensure the insured name matches the CSLB entity name. We may call the agent listed on the COI to confirm coverage is active.
Thanks,
[Your Name]
Script #3: Permit responsibility
Hi [Name],
Please confirm who will pull the electrical and gas/plumbing permits for this project and provide permit record numbers once submitted. We also want the inspection schedule and sign-offs saved in our project file.
Thank you,
[Your Name]
Red Flags That Expose Sloppy Subcontractor Management
- “We don’t use subs” while the project clearly includes electrical/gas/walls that require trade partners.
- “We have a guy” with no license number or COIs.
- Owner-builder push to have you pull permits or hire trades directly.
- Cash discounts paired with weak paperwork and no verification.
- Refusal to provide COIs or “we’ll send later.”
- No lien release process or dismissing releases as unnecessary.

- COI insured names match CSLB entity names exactly.
- I confirmed permit responsibility and received permit record numbers (gas/electrical as applicable).
- I am collecting lien releases with each progress payment.
- I am saving documentation in a project folder (CSLB screenshots, COIs, endorsements, permits, inspections, releases).
FAQs: Subcontractors on Outdoor Living Projects
Is it normal for a contractor to use subcontractors?
Yes. It’s common and often desirable. The key is whether subcontractors are licensed, insured, and managed with permits, documentation, and lien-release discipline.
Should I sign separate contracts with subcontractors?
Usually no. In a typical design-build relationship, the prime contractor holds the contract and remains responsible for managing subs. If you are asked to contract directly with trades, understand how that changes liability, permits, and lien-release management.
What if a contractor says a sub doesn’t need to be licensed?
For most outdoor living projects, major trades should be licensed. California’s minor work exemption is narrow (small dollar amount, no permits, no employees) and does not apply to complex outdoor living scopes that require permits or multiple workers.
How do I protect myself from lien risk created by subs?
Use lien releases paired with payments and keep good documentation. Conditional releases before paying, unconditional releases after payment clears. For full detail and official forms, use CSLB mechanics lien resources.
Can INSTALL-IT-DIRECT help me review a contractor’s sub list and paperwork?
Yes. We can help you evaluate the sub list, CSLB verification, COIs, permit responsibility, and lien-release plan as part of due diligence. For legal advice, consult an attorney.
Educational only. Always verify licensing and insurance directly through CSLB and the insurer/broker listed on COIs. Permit requirements vary by jurisdiction and parcel overlays.
