Do electrical contractors need to send a preliminary notice?

A preliminary notice is a written document sent to the property owner, general contractor, and construction lender at the start of a project. It tells them your company is furnishing labor or materials and preserves your right to file a mechanics lien if you are not paid. It is not a lien or a threat. Most states require it.

In most states, yes. Electrical contractors usually work as subcontractors under the GC, and that distance from the property owner is what triggers the notice requirement. Sending one on every private commercial project protects you even where the law does not demand it.

You can permanently forfeit your mechanics lien rights for that project. A notice sent one day late is invalid in strict-deadline states. Your remaining recourse is a breach-of-contract claim, which carries no secured interest in the property.

A preliminary notice goes out at the start of a project and preserves your right to file a lien. A notice of intent to lien goes out after a payment problem develops and warns the owner and GC that a lien is coming if the balance is not resolved. The preliminary notice must come first for the notice of intent to have legal backing.

Most states require names and addresses for the sender, property owner, general contractor, and construction lender, plus a description of the labor or materials, the project address, and an estimated value of the work. Some states mandate a statutory form that must be used exactly as written.
