Section 1947.15.
Cal. Civil Code - CIV § 1947.15.
in effect(a)
The Legislature declares the purpose of this section is to:
(1)
Ensure that owners of residential rental units that are subject to a system of controls on the price at which the units may be offered for rent or lease, or controls on the adjustment of the rent level, are
not precluded or discouraged from obtaining a fair return on their properties as guaranteed by the United States Constitution and California Constitution because the professional expenses reasonably required in the course of the administrative proceedings, in order to obtain the rent increases necessary to provide a fair return, are not treated as a legitimate business expense.
(2)
Encourage agencies which administer a system of controls on the price at which residential rental units may be offered for rent or lease, or controls the adjustment of the rent level, to enact streamlined administrative procedures governing rent adjustment petitions which minimize, to the extent possible, the cost and expense of these administrative proceedings.
(3)
Ensure that the cost of professional services reasonably incurred and required by owners of residential rental units subject to a system of
controls in the price at which the units may be offered for rent or lease, or controls on the adjustments of the rent level in the course of defending rights related to the rent control system, be treated as a legitimate business expense.
(b)
Any city, county, or city and county, including a charter city, which administers an ordinance, charter provision, rule, or regulation that controls or establishes a system of controls on the price at which all or any portion of the residential rental units located within the city, county, or city and county, may be offered for rent or lease, or controls the adjustment of the rent level, and which does not include a system of vacancy decontrol, as defined in subdivision (i), shall permit reasonable expenses, fees, and other costs for professional services, including, but not limited to, legal, accounting, appraisal, bookkeeping, consulting, property management, or architectural services, reasonably
incurred in the course of successfully pursuing rights under or in relationship to, that ordinance, charter provision, rule, or regulation, or the right to a fair return on an owner’s property as protected by the United States Constitution or California Constitution, to be included in any calculation of net operating income and operating expenses used to determine a fair return to the owner of the property. All expenses, fees, and other costs reasonably incurred by an owner of property in relation to administrative proceedings for purposes specified in this subdivision shall be included in the calculation specified in this subdivision.
(c)
Reasonable fees that are incurred by the owner in successfully obtaining a judicial reversal of an adverse administrative decision regarding a petition for upward adjustment of rents shall be assessed against the respondent public agency which issued the adverse administrative decision, and shall not be
included in the calculations specified in subdivisions (b) and (d).
(d)
(1)
Notwithstanding subdivision (b), the city, county, or city and county, on the basis of substantial evidence in the record that the expenses reasonably incurred in the underlying proceeding will not reoccur annually, may amortize the expenses for a period not to exceed five years, except that in extraordinary circumstances, the amortization period may be extended to a period of eight years. The extended amortization period shall not apply to vacant units and shall end if the unit becomes vacant during the period that the expense is being amortized. An amortization schedule shall include a reasonable rate of interest.
(2)
Any determination of the reasonableness of the expenses claimed, of an appropriate amortization period, or of the award of an upward adjustment of rents to compensate
the owner for expenses and costs incurred shall be made as part of, or immediately following, the decision in the underlying administrative proceeding.
(e)
Any and all of the following factors shall be considered in the determination of the reasonableness of the expenses, fees, or other costs authorized by this section:
(1)
The rate charged for those professional services in the relevant geographic area.
(2)
The complexity of the matter.
(3)
The degree of administrative burden or judicial burden, or both, imposed upon the property owner.
(4)
The amount of adjustment sought or the significance of the rights defended and the results obtained.
(5)
The relationship of the result obtained to the expenses, fees, and other costs incurred (that is, whether professional assistance was reasonably related to the result achieved).
(f)
This section shall not be applicable to any ordinance, rule, regulation, or charter provision of any city, county, or city and county, including a charter city, to the extent that the ordinance, rule, or regulation, or charter provision places a limit on the amount of rent that an owner may charge a tenant of a mobilehome park.
(g)
For purposes of this section, the rights of a property owner shall be deemed to be successfully pursued or defended if the owner obtains an upward adjustment in rents, successfully defends his or her rights in an administrative proceeding brought by the tenant or the local rent board, or prevails in a proceeding,
brought pursuant to Section 1947.8 concerning certification of maximum lawful rents.
(h)
(1)
If it is determined that a landlord petition assisted by attorneys or consultants is wholly without merit, the tenant shall be awarded a reduction in rent to compensate for the reasonable costs of attorneys or consultants retained by the tenant to defend the petition brought by the landlord. The reasonableness of the costs of the tenant’s defense of the action brought by the landlord shall be determined pursuant to the same provisions established by this section for determining the reasonableness of the landlord’s costs for the professional services. The determination of the reasonableness of the expenses claimed, an appropriate amortization period, and the award of a reduction in rents to compensate the tenant for costs incurred shall be made immediately following the decision in the underlying administrative proceeding.
(2)
If it is determined that a landlord’s appeal of an adverse administrative decision is frivolous or solely intended to cause unnecessary delay, the public agency which defended the action shall be awarded its reasonably incurred expenses, including attorney’s fees, in defending the action. As used in this paragraph, “frivolous” means either (A) totally and completely without merit; or (B) for the sole purpose of harassing an opposing party.
(i)
For purposes of this section, the following terms shall have the following meanings:
(1)
“Vacancy decontrol” means a system of controls on the price at which residential rental units may be offered for rent or lease which permits the rent to be increased to its market level, without restriction, each time a vacancy occurs. “Vacancy decontrol” includes systems which reimpose
controls on the price at which residential rental units may be offered for rent or lease upon rerental of the unit.
(2)
“Vacancy decontrol” includes circumstances where the tenant vacates the unit of his or her own volition, or where the local jurisdiction permits the rent to be raised to market rate after an eviction for cause, as specified in the ordinance, charter provision, rule, or regulation.
(j)
This section shall not be construed to affect in any way the ability of a local agency to set its own fair return standards or to limit other actions under its local rent control program other than those expressly set forth in this section.
(k)
This section is not operative unless the Costa-Hawkins Rental Housing Act (Chapter 2.7 (commencing with Section 1954.50) of Title 5 of Part 4 of Division 3) is
repealed.
