(A) Every provision of this code shall be construed liberally in favor of the city, and every regulation set forth herein shall be considered the minimum requirement for the promotion of the public health, safety and welfare.
(B) More restrictive requirements apply. Whenever the requirements of this code differ from those of any statute, lawfully adopted ordinance or regulation, easement, covenant or deed restriction, the more stringent requirement shall prevail. Thus, in accordance with state law whenever this code imposes higher standards than the County Subdivision Code, said higher standards shall supersede the county regulations in the unincorporated territory located within the city’s subdivision jurisdiction.
