Overview:

The risks associated with the construction lending industry’s “mechanics lien law” are the most draconian and punitive in real estate. These laws, due to their complexity and potential consequences, often necessitate the involvement of a lawyer to guide the property owner through the liability maze.

·       A mechanic’s lien is a “cloud” against the property title.

·       Any unpaid contractor, subcontractor, laborer, or material supplier can record a lien with the county recorder’s office for lack of payment.

·       The claimant is allowed to file a suit, begin a foreclosure action, and force the sale to pay off the lien.

·       The mechanics’ lien notification period begins at the point of the first drop of a surveyor’s markers, the first evidence of work in progress, the first supplies delivered to the property, or the first shovel in the ground.

Upon completion, the contractor will file a “California Notice of Completion,” which will shorten the mechanics’ lien period for subcontractors and suppliers. If a notice of completion is not filed, contractors and suppliers have 90 days from the date of completion to file a mechanics lien. If a notice is filed on time, within the 90 days, general contractors have only 60 days to file a lien, while suppliers and subcontractors have 30 days.
