License
What Los Angeles asks of a metal and glass business, and where your website comes in.
Checked 2026-10-05 at each source. Not legal advice: rules change, so check with the board before you rely on one.
State · California Contractors State License Board (CSLB)
Metal and glass work splits across four classifications. Advertise the ones you hold, with the number.
“Every person licensed pursuant to this chapter shall include his license number in: (a) all construction contracts; (b) subcontracts and calls for bid; and (c) all forms of advertising”
What it covers
“A glazing contractor selects, cuts, assembles and/or installs all makes and kinds of glass, glass work, mirrored glass, and glass substitute materials for glazing; executes the fabrication and glazing of frames, panels, sashes and doors; and/or installs these items in any structure.”
“An ornamental metals contractor assembles, casts, cuts, shapes, stamps, forges, welds, fabricates and installs, sheet, rolled and cast, brass, bronze, copper, cast iron, wrought iron, monel metal, stainless steel, steel, and/or any other metal for the architectural treatment and ornamental decoration of structures.”
“A structural steel contractor fabricates and erects structural steel shapes and plates, of any profile, perimeter or cross-section, that are or may be used as structural members for buildings and structures, including the riveting, welding, rigging and metal roofing systems necessary to perform this work.”
“A welding contractor causes metals to become permanently attached, joined and fabricated by the use of gases and electrical energy, which creates temperatures of sufficient heat to perform this work.”

CSLB counts any website or post that asks for work on the internet as advertising.

Advertise only the work your classification covers, and never say you are bonded.
CSLB, Advertising Guidelines for ContractorsOn your website
Put the number in the footer of every page and beside every quote form, under the business name it is issued to. Read every page as an ad: that is the safe reading of these rules.
