(b) For purposes of this section:

1. (1) “Substantially damaged or destroyed” means the structure sustains physical damage amounting to more than 50 percent of its full cash value immediately prior to the damage.
2. (2) “Similar in function” means the replacement structure is subject to similar governmental restrictions, including, but not limited to, zoning.

3. (3) “Similar in size and utility” means the size and utility of the structure are interrelated and associated with its value. A structure is similar in size and utility only to the extent that the replacement structure is, or is intended to be, used in the same manner as the substantially damaged or destroyed structure, and its full cash value does not exceed 120 percent of the full cash value of the replaced structure if that structure was not contaminated. For purposes of this paragraph:

   1. (A) A replacement structure or any portion thereof used or intended to be used for a purpose substantially different than the use made of the replaced structure, shall, to the extent of the dissimilar use, be considered not similar in utility.
   2. (B) A replacement structure or portion thereof that satisfies the use requirement but has a full cash value that exceeds 120 percent of the full cash value of the structure if that property were not contaminated, will be considered, to the extent of the excess, not similar in utility and size.
4. (4) To the extent that replacement property, or any portion thereof, is not similar in function, size, and utility, the property, or portion thereof, shall have a new base year value determined pursuant to Section 110.1.

(d) In order to receive the exclusion provided for in this section, the property owner shall notify the assessor in writing that he or she intends to claim the exclusion prior to, or within 30 days of, completion of any project covered by this section. All documents necessary to support the exclusion shall be filed by the property owner with the assessor not later than six months after the completion of the property. A claimant shall not be eligible for the exclusion provided by this section unless the claimant provides to the assessor the following information:

1. (1) Proof that the claimant did not participate in, or acquiesce to, any act or omission that rendered the real property uninhabitable or unusable, as applicable, or is related to any individual or entity that committed that act or omission.
2. (2) Proof that the qualified contaminated property has been designated as a toxic or environmental hazard or as an environmental cleanup site by an agency of the State of California or the federal government.
3. (3) The address and, if known, the assessor’s parcel number of the qualified contaminated property.
4. (4) The date of the claimant’s purchase and the date of completion of new construction.
