Before you hire a contractor in Los Angeles

Quick checklist any homeowner can use — these are the 8 things that distinguish hiring well from getting burned.

1Get at least 3 written quotes

Itemized scope + materials + timeline. One quote is a guess; three is data.

2Verify the license is active

Look up the number directly on California CSLB — not just a screenshot from the contractor.

3Request a current Certificate of Insurance

General liability AND workers' comp. Have the insurer email it directly — never accept a PDF from the contractor.

4Ask for 3 recent references

Same trade, same scope, completed in the last 12 months. Call them.

5Get a written contract

Scope, payment schedule, start & completion dates, change-order process, warranty terms.

6Never pay 100% upfront

Standard: 10–30% deposit, progress draws tied to milestones, final 10% on punch-list completion.

7Use lien waivers

Get a conditional waiver with every payment and an unconditional waiver at final payment. Protects your title.

8Confirm permits are pulled

For anything structural, electrical, plumbing, or HVAC — the contractor (not you) pulls the permit. No permit = no recourse if work fails inspection.
