California Code, Streets and Highways Code - SHC § 36704

(a) Nothing in this part is intended to preempt the authority of a charter city to adopt ordinances providing for a different method of levying assessments for similar or additional purposes from those set forth in this part.

(b) A multifamily improvement district created pursuant to this part is expressly exempt from the provisions of the Special Assessment Investigation, Limitation and Majority Protest Act of 1931 (Division 4 (commencing with Section 2800)).

(c) Any provision in this part that conflicts with any other provision of law shall prevail over the other provision of law.

(d) This part is intended to be construed liberally and, if any provision is held invalid, the remaining provisions shall remain in full force and effect.

(e) Assessments levied under this part are not special taxes.

(f) Consistent with Article XIII C of the California Constitution, no assessment shall be imposed under this part on any property which exceeds the reasonable cost of the proportional special benefit conferred on that property. Only special benefits are assessable, and a city shall separate the general benefits from the special benefits conferred on any property.
