Cal. Code Regs. tit. 18, § 1521
(a) Definitions.
(1) Construction Contract.
(A) “Construction contract” means and includes a contract, whether on a lump sum, time and material, cost plus, or other basis, to:
(B) “Construction contract” does not include:
(b) Application of Tax.
(1) United States Construction Contractors.
(2) Construction Contractors Other than United States Construction Contractors.
(A) Materials.
2. When Contractor is Seller. A construction contractor may contract to sell materials and also to install the materials sold. If the contract explicitly provides for the transfer of title to the materials prior to the time the materials are installed, and separately states the sale price of the materials, exclusive of the charge for installation, the contractor will be deemed to be the retailer of the materials.
In the case of a time and material contract, if the contractor bills his or her customer an amount for “sales tax” computed upon his or her marked up billing for materials, it will be assumed, in the absence of convincing evidence to the contrary, that he or she is the retailer of the materials.
If the sale occurs in this state, the sales tax applies to the contractor's (retailer's) gross receipts from the sale of the materials. If the sale occurs prior to the time the property is brought into this state, the contractor's (retailer's) customer is the consumer and his or her use (unless otherwise exempt) is subject to use tax measured by the sales price. The contractor must collect the use tax and pay it to this state.
(B) Fixtures.
2. Measure of Tax.
b. Determining Cost Price.
If the contractor purchases the fixtures in a completed condition, the cost price is deemed to be the sale price of the fixture to him or her and shall include any manufacturer's excise tax or import duty imposed with respect to the fixture prior to its sale by the contractor.
If the contractor is the manufacturer of the fixture, the cost price is deemed to be the price at which similar fixtures in similar quantities ready for installation are sold by him or her to other contractors.
If similar fixtures are not sold to other contractors ready for installation, then the cost price shall be deemed to be the amount stated in the price lists, bid sheets or other records of the contractor.
If the sale price cannot be established in the above manner and the fixture is manufactured by the contractor, the cost price shall be deemed to be the aggregate of the following:
[1] Cost of materials, including such items as freight-in and import duties,
[2] Direct labor, including fringe benefits and payroll taxes,
[3] Specific factory costs attributable to the fixture,
[4] Any manufacturer's excise tax,
[5] Pro rata share of all overhead attributable to the manufacture of the fixture, and
[6] Reasonable profit from the manufacturing operation which, in the absence of evidence to the contrary, shall be deemed to be 5 percent of the sum of the preceding factors.
Jobsite fabrication labor and its prorated share of manufacturing overhead must be included in the sale price of the fixture. Jobsite fabrication labor includes assembly labor performed prior to attachment of a component or a fixture to a structure or other real property.
3. Exceptions-Leased Fixtures. In some instances the construction contractor may furnish and install a fixture for a person, other than the owner of the realty, who intends to lease the fixture in place as tangible personal property as provided in section 6016.3 of the Revenue and Taxation Code and pay tax measured by rental receipts.
In this case the construction contractor may take a resale certificate from the lessor at the time of the transaction and the sale to the lessor will be considered to be a sale for resale. The resale certificate should indicate that the fixture is purchased for resale by the purchaser as tangible personal property under section 6016.3 of the Revenue and Taxation Code.
(C) Machinery and Equipment.
2. Measure of Tax.
b. Lump Sum Contracts-Determining Gross Receipts. If the contract is for a lump sum and includes the furnishing and installation of materials, fixtures, and machinery and equipment, the gross receipts from the sale of the machinery and equipment shall be the price at which similar quantities ready for installation are sold at retail delivered in the market area where the installation takes place.
If there is no such retail price for the machinery and equipment, then the gross receipts shall be determined from the contracts, price lists, bid sheets, or other records of the contractor.
If the gross receipts cannot be established in the above manner and the machinery and equipment is manufactured by the contractor, the gross receipts from the sale shall be the aggregate of the following:
[1] Cost of materials, including such items as freight-in and import duties,
[2] Direct labor, including fringe benefits and payroll taxes,
[3] Specific factory costs attributable to the machinery or equipment,
[4] Any manufacturer's excise tax,
[5] Pro rata share of all overhead attributable to the machinery or equipment, including overhead attributable to manufacturing, selling, contracting, and administration, and
[6] Reasonable profit from the manufacture and sale of the machinery or equipment which, in the absence of evidence to the contrary, shall be deemed to be 5 percent of the sum of the preceding factors.
Jobsite fabrication labor and its prorated share of manufacturing overhead must be included in the sale price of the machinery or equipment. Jobsite fabrication labor includes assembly labor performed prior to attachment of a component or the machinery or equipment to a structure or other real property.
(6) Exemption Certificates.
(A) Resale Certificates. Contractors holding valid seller's permits may purchase fixtures and machinery and equipment for resale by issuing resale certificates to their suppliers. They may not purchase materials for resale unless they are also in the business of selling materials.
A contractor cannot avoid liability for sales or use tax on materials or fixtures furnished and installed by him or her by taking a resale certificate from the prime contractor, interior decorators, designers, department stores, or others. However, under the circumstances described in subsection (b) (2) (B)3., a contractor may take a resale certificate for fixtures furnished and installed by him or her for a person other than the owner of the realty.
(B) Exemption Certificates for Out-of-State Use. Sales tax does not apply to sales of tangible personal property to a construction contractor who holds a valid California seller's permit when the property is used by the contractor outside this state in his or her performance of a contract to improve real property and as a result of such use the property is incorporated into and becomes a part of real property located outside this state. This exemption is available only if at the time of the purchase the contractor certifies in writing to the seller that he or she holds a valid California seller's permit (giving the number of that permit and identifying the property purchased) and states that the property will be used in the manner stated above. The certificate must be signed by the contractor or an authorized employee. Such a certification may appear in the body of a purchase order which bears the signature of the purchaser. Any certificate given subsequent to the time of purchase will not be recognized.
If the property purchased under a certificate is used by the contractor in any other manner or for any other purpose than stated in the certificate, the contractor shall be liable for sales tax as if he or she were a retailer making a retail sale of the property at the time of such use, and the sale price of the property to him or her shall be deemed the gross receipts from the sale.
(c) Particular Applications.
(1) Draperies and Drapery Hardware. Persons who contract to sell and install draperies including drapery hardware, such as brackets, rods, tracks, etc., are retailers of the items which they furnish and install. Tax applies to the entire contract price exclusive of the charge for installation which charge should be separately stated. Installers who furnish drapery hardware or other tangible personal property may accept resale certificates from department stores or other sellers to furnish and install the draperies and drapery hardware.
The department stores or other sellers furnishing resale certificates are required to pay the tax to the state upon their selling price of the draperies and drapery hardware, exclusive of installation charges. The installer should segregate his or her installation charge in order that the department store or other seller may properly segregate its charge attributable to installation for purposes of determining its taxable gross receipts.
(3) Prefabricated Buildings. Prefabricated units such as commercial coaches, house trailers, etc., registered with the Department of Motor Vehicles or the Department of Housing and Community Development, are tangible personal property even though they may be connected to plumbing and utilities. A mobilehome which meets or is modified to meet, all applicable building codes and regulations and which is permanently affixed to realty, is an improvement to realty and is not personal property.
A contract to furnish and install a prefabricated or modular building which is not a factory-built school building (relocatable classroom) is a construction contract whether the building rests in place by its own weight or is physically attached to realty. It is immaterial whether the building is erected upon or affixed to land owned by the owner of the building or is leased to the landowner or lessee of the land.
Generally, a contract to furnish and install a small prefabricated building, such as a shed or kiosk, which is movable as a unit from its site of installation, is a construction contract only if the building is required to be physically attached to real property by the seller, upon a concrete foundation or otherwise. The sale of such a unit to rest in place by its own weight, whether upon the ground, a concrete slab, or sills or piers, is not a construction contract even though the seller may deliver the unit to its site of use.
Prefabricated or modular buildings which are “factory-built housing” where permanently affixed to the realty are improvements to realty. The manufacturer of factory-built housing who contracts to furnish and install the factory-built housing manufactured by him or her is the consumer of the materials used in building and installing the factory-built housing and the retailer of the fixtures. Tax applies as provided in (b) above.
(4) Factory-built School Buildings.
(B) Definitions.
1. “Factory-built School Building.” The term “factory-built school building” (relocatable classroom) means and includes:
b. effective September 13, 1990, any building which is designed or intended for use as a school building and is wholly or substantially manufactured at an offsite location for the purpose of being assembled, erected, or installed on a site owned or leased by a school district or a community college district. A factory-built school building must be designed and manufactured in accordance with building standards adapted and approved pursuant to chapter 4 (commencing with section 18935) of part 2.5 of division 13 of the Health and Safety Code and must be approved by the structural safety section in the office of the State Architect.
The term does not include buildings licensed by either the Department of Motor Vehicles or the Department of Housing and Community Development. The term also does not include prefabricated or modular buildings which are similar in size to, but which are not, “factory-built school buildings”. It is immaterial whether the building is erected upon or affixed to land owned by the owner of the building or is leased to the landowner or lessee of the land.
2. “Consumer.”
a. For the period September 26, 1989 through September 12, 1990, the term “consumer” as used herein means either
b. Effective September 13, 1990, the term “consumer” as used herein means either
(D) Application of Tax.
1. Tax applies to 40 percent of the sales price of the building to the consumer excluding any charges for placing the completed building on the site. The sales price of the building shall include amounts representing tangible personal property installed in the building by a subcontractor, whether prior to or after installation of the building at the site, provided such installation is called for in the prime contract for the building.
A separate contract to furnish and install tangible personal property in a factory-built school building after installation of the building at the site is a construction contract and the tax applies as in (b) above. Any contract or subcontract for site preparation (e.g., foundation) is a construction contract and tax applies as in (b) above.
E. Exclusion Certificate. For the period September 26, 1989, through September 12, 1990, if the purchaser certifies in writing to the retailer that the factory built school building purchased will be consumed in a manner or for a purpose entitling the retailer to exclude 60% of the gross receipts or sales price from the measure of tax and uses the property in some other manner or for some other purpose, the purchaser shall be liable for payment of tax measured by 60% of the sales price. For the above stated period, all retailers who make retail sales of “factory-built school buildings” claimed to be subject to tax measured by 40 percent of the sales price must obtain from the “consumer” a signed certificate substantially in the form set forth below.
CLAIM FOR 60% EXCLUSION FROM TAX ON PURCHASE OF FACTORY-BUILT SCHOOL BUILDINGS
(Sec. 6012.6. Rev. & Tax. Code)
I hereby certify that the factory-built school building that I
(Name of Purchaser-Consumer)
am purchasing under the authority of this certificate from
(Name of Retailer)
will be used as a school building as defined in Sales and Use Tax Regulation 1521. My seller's permit number, if any, is ____________________.
I further certify that I understand and agree that if the property purchased under the authority of this certificate is used by the purchaser for any purpose other than indicated above, the purchaser shall be liable for payment of tax to the State Board of Equalization at the time of such use measured by 60% of the sales price of the factory-built school building.
Signed by
(Name of Purchaser)

(5) Mobilehomes Installed for Occupancy as Residences.
Operative July 1, 1980, a special measure of sales or use tax is provided for a mobilehome sold to be affixed to realty for occupancy as a residence.
A mobilehome dealer who sells a new mobilehome to a construction contractor to be affixed to land for occupancy as a residence is the “retailer-consumer” of the property and is required to pay tax for the period in which the sale was made by the dealer measured by an amount equal to 75 percent of the retailer-consumer's purchase price of the mobilehome.
A construction contractor who withdraws a new mobilehome from an inventory purchased for resale to be affixed to realty for occupancy as a residence in the performance of a construction contract is required to pay tax measured by 75 percent of the purchase price by his or her mobilehome vendor except where the purchase is made directly from a mobilehome manufacturer. In the absence of satisfactory evidence of the vendor's purchase price it shall be presumed that the measure of tax for the transaction is an amount equivalent to 60 percent of the sales price of the mobilehome to the construction contractor.
A mobilehome manufacturer who sells a new mobilehome directly to a construction contractor for installation to real property for occupancy as a residence is required to pay tax measured by 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. A construction contractor who withdraws a new mobilehome from an inventory purchased from a manufacturer for resale must pay tax measured by 75 percent of his or her purchase price.
A mobilehome manufacturer who performs a construction contract by permanently affixing a new mobilehome to real property is the consumer of the material and the retailer of fixtures installed by him or her and the tax applies as set forth in paragraph (b) above.
Reference should also be made to the provisions of Regulation 1610.2 for additional interpretative rules relating to custom additions to the mobilehome prior to sale, transfers of nonvehicle items, and the application of the tax to a purchase made from an out-of-state retailer.
(6) Repair Contracts. A contract to repair a fixture in place or a fixture the contractor is required by the contract to reaffix to the realty is a construction contract. Sales or use tax applies to the gross receipts or sales price of the parts sold by a contractor who is a retailer under this provision. Either sales tax or use tax applies to the sales price of the parts sold to or used by a contractor who is a consumer under this provision.
(B) Construction Contractors Other Than United States Construction Contractors.
(7) Elevator Installations. A large number of components are included in the installation of an elevator system. Those portions constituting the cage or platform and its hoisting machinery are fixtures. The balance of the installation, if attached to a structure or other real property will generally be “materials.”
Similarly, installation of escalators and moving sidewalks are in part fixtures and in part materials.
Following are examples of components constituting part of the cage or platform and its hoisting machinery, and which are fixtures:
alarm bell
cab or car
car doors
car platform and sling
door hanger on cab
door openers
door operator on cab or car
door safety edge on cab
door sills on cab
electronic door protector
jack assembly
motors
power units and control boxes
pumps
pushbuttons on cab
wire and piping (which are components of a fixture)
Following are examples of components constituting “materials” when attached to realty:
car guides
casing section of jack assembly
guide rails
hoistway doors
hoistway door frames
hoistway door safety edge
hoistway door sills and jambs
hoistway door supports
hoistway entrance
pushbuttons on hoistway
rail brackets
sill, struts
sound insulating panels on “materials”
structural steel (unless part of cab, car, or other “fixture”)
valve strainer
wire and piping attached to “materials”
Following are examples of components constituting parts of escalators or moving sidewalks which are fixtures:
staircase
moving sidewalk
moving handrails
chains
sprockets
motors
other operating mechanisms
(8) Telephone Switchboards and Instruments. Telephone switching equipment installed in a building specifically designed to accommodate the equipment or attached to a building or structure in a manner such that its removal would cause damage to the equipment or building in which it is installed will be considered to be “fixtures” under paragraph (a)(5) of this regulation.
Telephone handsets, modular switching equipment and standardized, off-shelf, general purpose switching equipment sold for use in general purpose office buildings constitute machinery and equipment under paragraph (a)(6) of this regulation. Handsets, modular switching equipment and standardized equipment were previously classified as fixtures.
This change in classification shall be applied prospectively only with respect to construction contracts entered into on and after July 1, 1988, by contractors other than United States construction contractors.
(9) Deep-Well Agricultural Pumps. A deep-well agricultural pump is tangible personal property if installed so that it rests in position by force of gravity and is not otherwise affixed to the land.
The pump is a fixture if:
(11) Excess Reimbursement.
The excess tax reimbursement provisions of Regulation 1700 apply to construction contractors.
(12) On-Premise Electric Signs
(B) Application of Tax. An on-premise electric sign is a fixture and tax applies to the sale price of the sign. Notwithstanding the provisions of 1521(b)(2)(B), operative October 1, 2000, if the contract does not state the sale price of the sign, tax applies to 33 percent of the contract price of on-premise electric signs that are furnished and installed by the seller. “Contract price” includes charges for materials, fabrication labor, installation labor, overhead, profit, and other charges associated with the sale and installation of the sign. If a contract provides that a contractor is to install an on-premise electric sign furnished by a third party, the charges for installation are not taxable. If a seller furnishes but does not install an on-premise electric sign, the seller is a retailer of the sign and tax applies to the total contract price.
Separately stated charges for transportation are subject to tax as defined in Regulation 1628, Transportation Charges.
(13) Solar Cells, Solar Panels and Solar Modules. A contract to furnish and install a solar energy system onto a structure or realty is a construction contract which involves furnishing and installing both materials and fixtures. A solar energy system is defined as any solar collector or other solar energy device that provides for the collection and distribution of solar energy and, where applicable, the storage of solar energy.
(A) Materials. Photovoltaic (PV) cells, solar panels and solar modules, including both solar thermal panels and solar electric PV panels, are considered materials when they function in the same manner as other materials such as roofing, windows, or walls and are incorporated into, attached to, or affixed to real property and, as such, lose their identity to become an integral and inseparable part of the real property. Examples of these types of solar panels include, but are not limited to, PV integrated skylights, PV panels used to function as a roof on a parking lot shade structure, and PV integrated roofing tiles.
Other materials include, but are not limited to, wiring, wiring harnesses, strapping, piping, and mounting systems. Mounting systems include rack framing brackets that are installed on roofs.
(B) Fixtures. Photovoltaic (PV) cells, solar panels and solar modules, including both solar thermal panels and solar electric PV panels, are considered fixtures when they are necessary to a building or other structure and do not lose their identity as accessories when installed. Examples of these types of solar panels include, but are not limited to, rack mounted solar panels installed on roofs and solar panels used in free-standing solar arrays.
Other items included in the solar energy system which are considered fixtures include, but are not limited to, terminal boxes, DC and AC disconnect boxes, inverters, transformers, batteries and pumps.
Contractors furnishing and installing solar energy systems that include fixtures are required to hold seller's permits as described in subdivision (b)(4).
(C) For the purposes of subdivisions (c)(13)(A) and (c)(13)(B), a charge for labor to affix solar panels purchased in a completed condition to a mounting system is not subject to tax.
