(a) For the purpose of this title, completion of a work of improvement occurs upon the occurrence of any of the following events:

(1) Actual completion of the work of improvement.

(2) Occupation or use by the owner accompanied by cessation of labor.

(3) Cessation of labor for a continuous period of 60 days.

(4) Recordation of a notice of cessation after cessation of labor for a continuous period of 30 days.

(b) Notwithstanding subdivision (a), if a work of improvement is subject to acceptance by a public entity, completion occurs on acceptance.

(a) An owner may record a notice of completion on or within 15 days after the date of completion of a work of improvement.

(b) The notice of completion shall be signed and verified by the owner.

(c) The notice shall comply with the requirements of Chapter 2 (commencing with Section 8100) of Title 1, and shall also include all of the following information:

(1) If the notice is given only of completion of a contract for a particular portion of the work of improvement as provided in Section 8186, the name of the direct contractor under that contract and a general statement of the work provided pursuant to the contract.

(2) If signed by the owner’s successor in interest, the name and address of the successor’s transferor.

(3) The nature of the interest or estate of the owner.

(4) The date of completion. An erroneous statement of the date of completion does not affect the effectiveness of the notice if the true date of completion is 15 days or less before the date of recordation of the notice.

(d) A notice of completion that does not comply with the provisions of this section is not effective.

(e) For the purpose of this section, “owner” means the owner who causes a building, improvement, or structure to be constructed, altered, or repaired, or that person’s successor in interest at the date a notice of completion is recorded, whether the interest or estate of the owner be in fee, as vendee under a contract of purchase, as lessee, or other interest or estate less than the fee. Where the interest or estate is held by two or more persons as joint tenants or tenants in common, any one or more of the cotenants may be deemed to be the “owner” within the meaning of this section.

A notice of completion in otherwise proper form, verified and containing the information required by this title, shall be accepted by the recorder for recording and is deemed duly recorded without acknowledgment.

If a work of improvement is made pursuant to two or more direct contracts, each covering a portion of the work of improvement:

(a) The owner may record a notice of completion of a direct contract for a portion of the work of improvement. On recordation of the notice of completion, for the purpose of Sections 8412 and 8414, a direct contractor is deemed to have completed the contract for which the notice of completion is recorded and a claimant other than a direct contractor is deemed to have ceased providing work.

(b) If the owner does not record a notice of completion under this section, the period for recording a claim of lien is that provided in Sections 8412 and 8414.

(a) An owner may record a notice of cessation if there has been a continuous cessation of labor on a work of improvement for at least 30 days prior to the recordation that continues through the date of the recordation.

(b) The notice shall be signed and verified by the owner.

(c) The notice shall comply with the requirements of Chapter 2 (commencing with Section 8100) of Title 1, and shall also include all of the following information:

(1) The date on or about which labor ceased.

(2) A statement that the cessation has continued until the recordation of the notice.

(d) For the purpose of this section, “owner” means the owner who causes a building, improvement, or structure to be constructed, altered, or repaired, or that person’s successor in interest at the date a notice of cessation is recorded, whether the interest or estate of the owner be in fee, as vendee under a contract of purchase, as lessee, or other interest or estate less than the fee. Where the interest or estate is held by two or more persons as joint tenants or tenants in common, any one or more of the cotenants may be deemed to be the “owner” within the meaning of this section.
