Licensed plumbers in Lancaster, CA (C-36 license records)

Verify before you hire. This is an independent directory, not a contractor. Listing a business is not an endorsement or guarantee. Each entry reflects what the public CSLB License Master file showed when downloaded October 26, 2026; status can change at any time. You contract with and pay the business directly.

Lancaster and the nearby unincorporated community of Quartz Hill are covered here. Lancaster’s own Building & Safety division issues permits and says online permit types include Residential Plumbing and Residential Water Heater permits.

What the 65 listings below have in common

Each business has an active license (status “CLEAR”, no secondary status or pending suspension) with the C-36 Plumbing classification in CSLB’s public file, a license expiration date more than 45 days after October 26, 2026, a contractor bond on file with no cancellation date, and workers’ compensation either on file (policy more than 45 days from ending) or an exemption on file. The CSLB file does not say which jobs a business takes, so this directory does not either — call and ask.

Before you call

1. Read how to check a license on CSLB and use the “Verify at CSLB” link on a listing, or enter the license number at CSLB’s Check a License page.
2. Ask for a written estimate. CSLB suggests comparing at least three written bids and being wary of a bid far lower than the rest.
3. Ask who will pull any permit the work needs. The City of Lancaster’s Building & Safety permits page lists what needs a permit; its online portal is at aca.accela.com/lancaster (Quartz Hill is unincorporated, so check with the permitting agency for your address).
