(2) “Energy efficient product or equipment” shall include, but not be limited to, heating, ventilation, air-conditioning, lighting, solar, advanced metering of energy usage, windows, insulation, zone heating products, and weatherization systems. (3) “Zone heating products” mean gas room heaters certified by the California Energy Commission or wood fueled stoves certified by the federal Environmental Protection Agency.

(a) Notwithstanding any other provisions in this part to the contrary, no deduction shall be allowed for interest, taxes, depreciation, or amortization paid or incurred in the taxable year with respect to substandard housing located in this state, except as provided in subdivision (e). (b) “Substandard housing” means occupied dwellings from which the taxpayer derives rental income or unoccupied or abandoned dwellings for which both of the following apply: (1) Either of the following occurs: (A) For occupied dwellings from which the taxpayer derives rental income, a state or local government regulatory agency has determined that the housing violates state law or local codes dealing with health, safety, or building. (B) For dwellings that are unoccupied or abandoned for at least 90 days, a state or local government regulatory agency has cited the housing for conditions that constitute a serious violation of state law or local codes dealing with health, safety, or building, and that constitute a threat to public health and safety. (2) Either of the following occurs: (A) After written notice of violation by the regulatory agency, specifying the applicability of this section, the housing has not been brought to a condition of compliance within six months after the date of the notice or the time prescribed in the notice, whichever period is later. (B) Good faith efforts for compliance have not been commenced, as determined by the regulatory agency. “Substandard housing” also means employee housing that has not, within 30 days of the date of the written notice of violation or the date for compliance prescribed in the written notice of violation, been brought into compliance with the conditions stated in the written notice of violation of the Employee Housing Act (Part 1 (commencing with Section 17000) of Division 13 of the Health and Safety Code) issued by the enforcement agency that specifies the application of this section. The regulatory agency may, for good cause shown, extend the compliance date prescribed in a violation notice. (c) (1) When the period specified in paragraph (2) of subdivision (b) has expired without compliance, the regulatory agency shall mail to the taxpayer a notice of noncompliance. The notice of noncompliance shall be in a form and shall include information prescribed by the Franchise Tax Board, shall be mailed by certified mail to the taxpayer at the taxpayer’s last known address, and shall advise the taxpayer of (A) an intent to notify the Franchise Tax Board of the noncompliance within 10 days unless an appeal is filed, (B) where an appeal may be filed, and (C) a general description of the tax consequences of the filing with the Franchise Tax Board. Appeals shall be made to the same body and in the same manner as appeals from other actions of the regulatory agency. If no appeal is made within 10 days or if after disposition of the appeal the regulatory agency is sustained, the regulatory agency shall notify, in writing, the Franchise Tax Board of the noncompliance. (2) The notice of noncompliance shall contain the legal description or the lot and block numbers of the real property, the assessor’s parcel number, and the name of the owner of record as shown on the latest equalized assessment roll. In addition, the regulatory agency shall, at the same time as notification of the notice of noncompliance is sent to the Franchise Tax Board, record a copy of the notice of noncompliance in the office of the recorder for the county in which the substandard housing is located that includes a statement of tax consequences that may be determined by the Franchise Tax Board. However, the failure to record a notice with the county recorder does not relieve the liability of any taxpayer nor does it create any liability on the part of the regulatory agency. (3) The regulatory agency may charge the taxpayer a fee in an amount not to exceed the regulatory agency’s costs incurred in recording any notice of noncompliance or issuing any release of that notice. The notice of compliance shall be recorded and shall serve to expunge the notice of noncompliance. The notice of compliance shall contain the same recording information required for the notice of noncompliance. No deduction by the taxpayer, or any other taxpayer who obtains title to the property subsequent to the recordation of the notice of noncompliance, shall be allowed for the items provided in subdivision (a) from the date of the notice of noncompliance until the date the regulatory agency determines that the substandard housing has been brought to a condition of compliance. The regulatory agency shall mail to the Franchise Tax Board and the taxpayer a notice of compliance, which notice shall be in the form and include the information prescribed by the Franchise Tax Board. In the event the period of noncompliance does not cover an entire taxable year, the deductions shall be denied at the rate of 1 12 for each full month during the period of noncompliance. (4) If the property is owned by more than one owner or if the recorded title is in the name of a fictitious owner, the notice requirements provided in subdivision (b) and this subdivision shall be satisfied for each owner if the notices are mailed to one owner or to the fictitious name owner at the address appearing on the latest available property tax bill. However, notices made pursuant to this subdivision do not relieve the regulatory agency from furnishing taxpayer identification information required to implement this section to the Franchise Tax Board. (d) For the purposes of this section, a notice of noncompliance shall not be mailed by the regulatory agency to the Franchise Tax Board if any of the following occur: (1) The housing was rendered substandard solely by reason of earthquake, flood, or other natural disaster except where the condition remains for more than three years after the disaster. (2) The owner of the substandard housing has secured financing to bring the housing into compliance with those laws or codes that have been violated, causing the housing to be classified as substandard, and has commenced repairs or other work necessary to bring the housing into compliance. (3) The owner of substandard housing that is not within the meaning of housing accommodation as defined by subdivision (d) of Section 35805 of the Health and Safety Code has done both of the following: (A) Attempted to secure financing to bring the housing into compliance with those laws or codes that have been violated, causing the housing to be classified as substandard. (B) Been denied that financing solely because the housing is located in a neighborhood or geographical area in which financial institutions do not provide financing for rehabilitation of any of that type of housing. (e) This section does not apply to deductions from income derived from property rendered substandard solely by reason of a change in applicable state or local housing standards unless the violations cause substantial danger to the occupants of the property, as determined by the regulatory agency which has served notice of violation pursuant to subdivision (b). (f) The owner of substandard housing found to be in noncompliance shall, upon total or partial divestiture of interest in the property, immediately notify the regulatory agency of the name and address of the person or persons to whom the property has been sold or otherwise transferred and the date of the sale or transference. (g) By July 1 of each year, the regulatory agency shall report to the appropriate legislative body of its jurisdiction all of the following information, for the preceding calendar year, regarding its activities to secure code enforcement, which shall be public information: (1) The number of written notices of violation issued for substandard housing under subdivision (b). (2) The number of violations complied with within the period prescribed in subdivision (b). (3) The number of notices of noncompliance issued pursuant to subdivision (c). (4) The number of appeals from those notices pursuant to subdivision (c). (5) The number of successful appeals by owners. (6) The number of notices of noncompliance mailed to the Franchise Tax Board pursuant to subdivision (c). (7) The number of cases in which a notice of noncompliance was not sent pursuant to subdivision (d). (8) The number of extensions for compliance granted pursuant to subdivision (b) and the mean average length of the extensions. (9) The mean average length of time from the issuance of a notice of violation to the mailing of a notice of noncompliance to the Franchise Tax Board where the notice is actually sent to the Franchise Tax Board. (10) The number of cases where compliance is achieved after a notice of noncompliance has been mailed to the Franchise Tax Board. (11) The number of instances of disallowance of tax deductions by the Franchise Tax Board resulting from referrals made by the regulatory agency. This information may be filed in a supplemental report in succeeding years as it becomes available. (h) The provisions of this section relating to substandard housing consisting of abandoned or unoccupied dwellings do not apply to any lender engaging in a “federally related transaction,” as defined in Section 11302 of the Business and Professions Code, who acquires title through judicial or nonjudicial foreclosure, or accepts a deed in lieu of foreclosure. The exception provided in this subdivision covers only substandard housing consisting of abandoned or unoccupied dwellings involved in the federally related transaction.

(4) In a case in which the legal form under which a trade or business activity is being conducted is changed, the change in form shall be disregarded and the determination of whether the trade or business activity is a new business shall be made by treating the taxpayer as having purchased or otherwise acquired all or any portion of the assets of an existing trade or business under the rules of paragraph (1). (5) “Related person” shall mean any person that is related to the taxpayer under either Section 267 or 318 of the Internal Revenue Code.

(ii) “Other biotechnology activities” means activities consisting of the application of recombinant DNA technology to produce commercial products, as well as activities regarding pharmaceutical delivery systems designed to provide a measure of control over the rate, duration, and site of pharmaceutical delivery.

(h) The Franchise Tax Board may prescribe appropriate regulations to carry out the purposes of this section, including any regulations necessary to prevent the avoidance of the purposes of this section through splitups, shell corporations, partnerships, tiered ownership structures, or otherwise. (i) The Franchise Tax Board may reclassify any net operating loss carryover determined under either paragraph (2) or (3) of subdivision (b) as a net operating loss carryover under paragraph (1) of subdivision (b) upon a showing that the reclassification is necessary to prevent evasion of the purposes of this section. (j) Except as otherwise provided, the amendments made by Chapter 107 of the Statutes of 2000 apply to net operating losses for taxable years beginning on or after January 1, 2000.

For purposes of this subdivision, all of the following shall apply: (1) A net operating loss shall not be a net operating loss carryback for any taxable year, and a net operating loss for any taxable year beginning on or after the date the area in which the taxpayer conducts a trade or business is designated the Los Angeles Revitalization Zone shall be a net operating loss carryover to each following taxable year that ends before the Los Angeles Revitalization Zone expiration date or to each of the 15 taxable years following the taxable year of loss, if longer. (2) “Net operating loss” means the loss determined under Section 172 of the Internal Revenue Code, as modified by Section 17276.1, attributable to the taxpayer’s business activities within the Los Angeles Revitalization Zone (as defined in Section 7102 of the Government Code) prior to the Los Angeles Revitalization Zone expiration date. The attributable loss shall be determined in accordance with Chapter 17 (commencing with Section 25101) of Part 11, modified as follows: (A) Loss shall be apportioned to the Los Angeles Revitalization Zone by multiplying total loss from the business by a fraction, the numerator of which is the property factor plus the payroll factor, and the denominator of which is 2.

(C) The payroll factor is a fraction, the numerator of which is the total amount paid by the taxpayer in the Los Angeles Revitalization Zone during the taxable year for compensation, and the denominator of which is the total compensation paid by the taxpayer in this state during the taxable year. (6) “Los Angeles Revitalization Zone expiration date” means the date the Los Angeles Revitalization Zone designation expires, is repealed, or becomes inoperative pursuant to Section 7102, 7103, or 7104 of the Government Code.

(c) A taxpayer who qualifies as a “qualified taxpayer” under one or more sections shall, for the taxable year of the net operating loss and any taxable year to which that net operating loss may be carried, designate on the original return filed for each year the section that applies to that taxpayer with respect to that net operating loss. If the taxpayer is eligible to qualify under more than one section, the designation is to be made after taking into account subdivision (d). (d) If a taxpayer is eligible to qualify under this section and either Section 17276.2, 17276.5, or 17276.6 as a “qualified taxpayer,” with respect to a net operating loss in a taxable year, the taxpayer shall designate which section is to apply to the taxpayer. (e) Notwithstanding Section 17276, the amount of the loss determined under this section or Section 17276.2, 17276.5, or 17276.6 shall be the only net operating loss allowed to be carried over from that taxable year and the designation under subdivision (c) shall be included in the election under Section 17276.1. (f) This section shall cease to be operative on December 1, 1998. However, any unused net operating loss may continue to be carried over to following years as provided in this section.
