Rev. & Tax. Code, § 6012.8

(a) For the purposes of this part, “gross receipts” from the sale of a new mobilehome, and the “sales price” of a new mobilehome sold or stored, used, or otherwise consumed in this state shall be 75 percent of the sales price of the mobilehome to the retailer, if the mobilehome is sold by the retailer to the purchaser for installation on a foundation system pursuant to Section 18551 of the Health and Safety Code for occupancy as a residence, and is thereafter subject to property taxation. The retailer shall be considered to be the consumer for purposes of this part if the sale by the retailer would otherwise have been subject to sales tax and if the retailer is not also the manufacturer of the mobilehome. If the retailer of the mobilehome is the manufacturer, tax shall be measured by an amount equal to 75 percent of the sales price at which a similar mobilehome ready for installation would be sold by the manufacturer to a retailer-consumer in this state.

Notwithstanding any other provision of this part, a retailer may give a resale certificate for the purchase by the retailer of such a mobilehome and shall report the gross receipts or sales price from the purchase with the return for the period during which the mobilehome is sold to the purchaser for installation for occupancy as a residence.

Notwithstanding any other provision of this part, any retailer who is a licensed mobilehome dealer under Section 18002.6 of the Health and Safety Code is a retailer-consumer regardless of whether or not it installs the mobilehome on a foundation system as an improvement to realty. The licensed dealer may give a resale certificate for the purchase of such a mobilehome, and shall report the gross receipts or sales price from the purchase with the return for the period during which the mobilehome is installed by the licensed dealer for occupancy as a residence.

(b) For purposes of this section, a “mobilehome” is defined in Sections 18008 and 18211 of the Health and Safety Code.

(c) If a purchaser certifies in writing to a retailer that the mobilehome purchased will be consumed in a manner or for a purpose entitling the retailer to exclude 25 percent of the gross receipts or sales price to the retailer from the measure of tax, and uses the property in some other manner or for some other purpose which would not be subject to any other exclusion or exemption under this part, the purchaser shall be liable for payment of tax measured by the amount of the sales price to the purchaser less an amount equal to 75 percent of the gross receipts or sales price of the mobilehome to the retailer.

(d) There are exempted from the taxes imposed by this part, the gross receipts from the sale of, and the storage, use, or other consumption in this state of any used mobilehome, the initial retail sale of which qualified for the partial exemption from tax provided for by this section.
