The total amount of credits allowed to a taxpayer under this section may not exceed six hundred dollars ($600) per structure.(b) For purposes of this section:
(1) “Hot water recirculating system” means a system of pipes with a motor driven pump that recirculates water between the hot water heater and the hot water faucets so that substantially all of the cold water in the pipes will be returned to the water heater and reheated before the faucet is turned on.
(2) “Qualified plumbing fixture” includes the following:
(A) Shower heads with a maximum flow capacity of two and one-half gallons per minute.
(B) Hot water faucets with more than 10 feet of pipe connecting the faucet to the hot water heater.
(3) “New construction” means the construction of a new structure, an addition to a preexisting structure, or the renovation or remodeling of a preexisting structure, but only with respect to the portion of the preexisting structure that is remodeled or renovated.
(4) “Structure” means a structure as described in subdivision (a) of Section 105, or any successor to that subdivision.
(c) In the case of any structure that has never been occupied for its intended purpose, the credit under this section may be allowed to the owner of the property on the date that the hot water recirculating system is installed.
(d) No deduction may be allowed under this part for any cost for which a credit is allowed by this section.
(e) To the extent that data are available, the Franchise Tax Board shall report annually to the Legislature regarding the utilization of the credits authorized by this section.
(f) In the case where the credit allowed by this section exceeds the “net tax,” the excess may be carried over to reduce the “net tax” in the following year, and for the six succeeding years if necessary, until the credit is exhausted.
(g) This section shall remain in effect only until December 1, 2006, and as of that date is repealed.
