Revenue and Taxation Code section 439.2
(a)
The annual income to be capitalized shall be determined as follows:(1)
Where sufficient rental information is available, the income shall be the fair rent that can be imputed to the restricted historical property being valued based upon rent actually received for the property by the owner and upon typical rentals received in the area for similar property in similar use where the owner pays the property tax. When the restricted historical property being valued is actually encumbered by a lease, any cash rent or its equivalent considered in determining the fair rent of the property shall be the amount for which the property would be expected to rent were the rental payment to be renegotiated in the light of current conditions, including applicable provisions under which the property is enforceably restricted.(2)
Where sufficient rental information is not available, the income shall be that which the restricted historical property being valued reasonably can be expected to yield under prudent management and subject to applicable provisions under which the property is enforceably restricted.(3)
If the parties to an instrument that enforceably restricts the property stipulate therein an amount that constitutes the minimum annual income to be capitalized, then the income to be capitalized shall not be less than the amount so stipulated.(b)
The capitalization rate to be used in valuing owner-occupied single-family dwellings pursuant to this article shall not be derived from sales data and shall be the sum of the following components:(1)
An interest component to be determined by the board and announced no later than October 1 of the year preceding the assessment year and that was the yield rate equal to the effective average interest rate on conventional mortgages as most recently published by the Federal Home Loan Mortgage Corporation, or as that entity may be known in the future, as of September 1, rounded to the nearest one-fourth of 1 percent.(2)
A historical property risk component of 4 percent.(3)
A component for property taxes that shall be a percentage equal to the estimated total tax rate applicable to the property for the assessment year times the assessment ratio.(4)
A component for amortization of the improvements that shall be a percentage equivalent to the reciprocal of the remaining life.(c)
The capitalization rate to be used in valuing all other restricted historical property pursuant to this article shall not be derived from sales data and shall be the sum of the following components:(1)
An interest component to be determined by the board and announced no later than October 1 of the year preceding the assessment year and that was the yield rate equal to the effective average interest rate on conventional mortgages as determined by the Federal Home Loan Mortgage Corporation, or as that entity may be known in the future, as of September 1, rounded to the nearest one-fourth of 1 percent.(2)
A historical property risk component of 2 percent.(3)
A component for property taxes that shall be a percentage equal to the estimated total tax rate applicable to the property for the assessment year times the assessment ratio.(4)
A component for amortization of the improvements that shall be a percentage equivalent to the reciprocal of the remaining life.(d)
Unless a party to an instrument that creates an enforceable restriction expressly prohibits the valuation, the valuation resulting from the capitalization of income method described in this section shall not exceed the lesser of either the valuation that would have resulted by calculation under Section 110, or the valuation that would have resulted by calculation under Section 110.1, as though the property was not subject to an enforceable restriction in the base year.(e)
The value of the restricted historical property shall be the quotient of the income determined as provided in subdivision (a) divided by the capitalization rate determined as provided in subdivision (b) or (c).(f)
The ratio prescribed in Section 401 shall be applied to the value of the property determined in subdivision (d) to obtain its assessed value.
