Cal. Rev. & Tax. Code § 2188.10

(a) Whenever the assessor receives a written request for separate assessment of a pro rata portion of the real property of a mobilehome park which changed ownership pursuant to subdivision (c) of Section 62.1 as the result of the transfer of a share or shares of voting stock or other ownership or membership interest or interests, the assessor shall, on the first lien date which occurs more than 60 days following the request, and on each lien date thereafter, separately assess the portion or portions of real property described in subdivision (b) if the conditions specified in subdivision (c) have been met. Whenever a portion of the real property of a mobilehome park becomes subject to separate assessment, it shall continue to be subject to separate assessment in subsequent fiscal years and once a request for separate assessment is made, it is binding on all future owners of the voting stock or other ownership or membership interests in the entity which owns the park.
(b) The interest that is to be separately assessed is the value of the pro rata portion of the real property of the mobilehome park which changed ownership pursuant to subdivision (c) of Section 62.1.
(c) A separate assessment may not be made by the assessor under this section unless the following conditions are met:
1. (1) The governing board of the mobilehome park makes the request for separate assessment and certifies that the request has been approved in the manner provided in the organizational documents of the entity owning the mobilehome park.
2. (2) Information is filed with the assessor listing all of the following:
  1. (A) The total number of outstanding shares of voting stock of, or other ownership or membership interests in, the entity which owns the mobilehome park.
  2. (B) The number of shares of voting stock, or other ownership or membership interests, which have been transferred and resulted in the change in ownership of portions of the real property of the park pursuant to subdivision (c) of Section 62.1, together with the names and addresses of the owners of the transferred voting stock or other ownership or membership interests.
  3. (C) Any other information as the assessor may require.
    The entity owning the mobilehome park shall file an annual statement for each succeeding assessment year, on or before April 1, with the assessor, setting forth any changes to the required information known to the entity. The information provided pursuant to this section is not a public document and shall not be open to public inspection, except as provided in Section 408.
(d) Nothing in this section shall be construed to require applicants for separate assessments to meet the requirements of the Subdivision Map Act, nor shall the approval of any governmental agency be required for separate assessment except for the assessor’s approval.
(e) The assessor shall cumulate all the separate assessments in a mobilehome park and enter the total assessment on the secured roll in the name of the entity which owns the park. The assessor shall notify each owner of a portion of the real property of the park subject to separate assessment under this section of the amount of an increased assessment pursuant to Section 619.
(f) The tax on the total assessment of the mobilehome park shall be a lien on the real property of the park and shall be subject to all provisions of law applicable to taxes on the secured roll.
(g) The tax collector shall send a single tax bill, with an itemized breakdown detailing the taxes and the allocated portion of any fee imposed pursuant to subdivision (i) applicable to each separate assessment, to the entity owning the mobilehome park.
(h) The assessor shall provide to owners of voting stock or other ownership or membership interest in a mobilehome park entity subject to subdivision (c) of Section 62.1, and to the governing board of the park, at that time and in that manner as the assessor deems appropriate, adequate notice of the provisions of this section and other pertinent information relative to the implementation thereof.
(i) The county may charge a fee for processing the application for separate assessment, and for the initial and ongoing costs of separate assessment and implementing subdivision (g), not to exceed actual costs. This fee shall be subject to Chapter 12.5 (commencing with Section 54985) of Part 1 of Division 2 of Title 5 of the Government Code, and shall be allocated to each owner of a share of voting stock or other ownership or membership interest for which a separate assessment has been made. The fee may be collected commencing with the initial separate tax bills, and on subsequent tax bills, and shall be deposited in the county’s general fund.
(j) The governing board of the entity which owns the mobilehome park shall collect the allocated portion of any fee charged pursuant to subdivision (i) and any itemized taxes applicable to a separate assessment from the owner of the voting stock or other ownership or membership interest whose acquisition of the interest resulted in the separate assessment. The fees and taxes resulting from separate assessment shall be deducted from the proportional cost of the fees and taxes collected from the remaining owners or members.
