California Code, Streets and Highways Code - SHC § 36701

(a) Many businesses that operate multifamily residential properties and commercial properties within predominantly multifamily neighborhoods of California's communities are economically disadvantaged, are underutilized, and are unable to attract tenants because of inadequate facilities, services, and activities in those neighborhoods.

(b) It is in the public interest to promote the economic revitalization and physical maintenance of the multifamily residential neighborhoods to create jobs, attract new businesses, and prevent the erosion of the multifamily residential neighborhoods.

(c) It is of particular local benefit to allow cities to fund business related improvements and activities through the levy of assessments upon the businesses or real property that benefit from those improvements.

(d) Assessments levied for the purpose of providing improvements and promoting activities that benefit real property or businesses are not taxes for the general benefit of a city, but are assessments for the improvements and activities that confer special benefits upon the real property or businesses for which the improvements and activities are provided.
