Research Los Angeles contractors: local profiles, license checks and permits.
Start with the work and the project address—not just a nearby company name. Use dated company research, verify the credentials relevant to your scope, compare written proposals and confirm which agency handles permits for the property.
Local guidance checked October 16, 2026. Each company profile retains its own research date. Contact companies directly; this guide requires no lead form.
Published Los Angeles-area company research—not a ranking
These examples cover different trades and locations. They are starting points for research, not a complete list, a promise of availability or a comparison of workmanship.
- High Quality Plumbing — Los Angeles; repiping, water-heater service, sewer work and residential plumbing. Profile research: September 28, 2026.
- Preferred Electric — Los Angeles; panels, wiring, lighting, troubleshooting and EV charging. Profile research: September 28, 2026. Its recorded Google observation had only one review; it should not be interpreted as a broad review consensus.
- Family Roofing, Inc. — Los Angeles; inspections, repair, replacement and shingle, tile and metal roofing. Profile research: September 28, 2026.
- Unitechs Heating & Air Conditioning — North Hollywood; HVAC installation, repair, maintenance, heat pumps, ductless systems and ducts. Profile research: October 16, 2026.
Locations are not verified service boundaries. Confirm service to your exact property. Neighboring municipalities such as Torrance and Pico Rivera should not be treated as Los Angeles City offices. Find additional dated research in the company directory.
First identify the permit authority for the property
City of Los Angeles
Start with the current Los Angeles Department of Building and Safety site. It links permit and plan-review services, PRISM for permit/records information, PermitLA for eligible simple permits and ePlanLA for plan-review workflows. Use the current agency guidance rather than an old saved application path.
Unincorporated Los Angeles County and nearby cities
County Public Works Building and Safety serves its jurisdiction and points to EPIC-LA for applications and inspections. City and County systems are not interchangeable; a nearby municipality may have its own department. Confirm jurisdiction from the project address, not just the postal city or contractor office.
Check the exact California business and work classification
Ask for the business’s legal name and CSLB license number, then use the official CSLB license lookup to examine current status, classifications and available complaint disclosures. A printed number, trade name or NHA recognition badge is not proof of current project-specific licensing.
CSLB’s hiring guidance also recommends checking insurance with the insurer or agency. Its guidance flags class-specific workers’ compensation requirements; do not assume a business needs no coverage merely because it reports no employees. Confirm what applies to the exact business and work.
NHA has not performed individual CSLB, insurance or permit checks for the examples on this page.
Compare permit responsibility, scope and written terms
Express permit does not mean permit-free
LADBS describes express permits as a route for eligible simple projects that do not require plan check—not a blanket permit exemption. Confirm the actual scope with the department or an appropriately qualified professional. Put responsibility for applications, fees, inspections and closeout in writing.
Ask for comparable proposals
CSLB recommends at least three written bids based on the same plans, specifications and scope. For roofing, distinguish repair from replacement and identify materials and flashing. For electrical work, separate troubleshooting, panel, wiring and EV-charger work. For plumbing, distinguish repiping from drains, sewer and water-heater work. For HVAC, specify equipment, duct changes, commissioning and maintenance.
Use current California contract guidance
Consult CSLB’s contracts and binding agreements guide for applicable written-contract and payment rules. Get the work, materials, exclusions, payment milestones, timing and changes documented. This page does not determine a particular project’s legal exemptions or contract eligibility.
Use dated evidence—and verify what the profile does not
Gold profiles document an exact BBB A+ record, a directly verifiable Google customer rating strictly above 4.3, identity matching, official service evidence and complaint-context review at the profile’s research date. Records and ratings can change; historical or special-recognition profiles explain their own basis.
NHA has not independently verified current licensing, bonding, certifications or insurance for the companies included here. Recognition does not guarantee workmanship, safety, results or current availability. Follow the original sources and verify the credentials relevant to your property and scope before hiring.
Continue with the research standards, directory, national contractor-research hub and homeowner resources. NHA is a private information resource, not a government agency. Advertisements and material relationships remain separately disclosed.
