(1) Over-insurance shall be deemed to exist if property or an insurable interest therein is insured by one or more insurance contracts against the same hazard in any amount in excess of the fair value of the property or of such interest, as determined as of the effective date of the insurance or of any renewal thereof, or in those instances when insured value is for improvements and land.
(2) For the purposes of this section only the term "fair value" means the cost of replacement less such depreciation as is properly applicable to the subject insured.
(3) No person shall knowingly require, request, issue, place, procure, or accept any insurance contract which would result in over-insurance of the property or interest therein proposed to be insured, except as is provided in RCW 48.27.020.
(4) No person shall compel an insured or applicant for insurance to procure property insurance in an amount in excess of the amount which could reasonably be expected to be paid under the policy (or combination of policies) in the event of a loss, whether such insurance is required in connection with a loan or otherwise.
(5) Each violation of this section shall subject the violator to the penalties provided by this code.
