If a gambling establishment is located in an unincorporated area annexed by a city, notwithstanding Section 19960 or 19962, without a local election other than the election to approve the annexation, the city acquiring jurisdiction may adopt an ordinance permitting and regulating controlled gaming in the existing gambling establishment, providing hours of operation, the games to be played, wagering limits, the maximum number of gambling establishments, and the maximum number of tables permitted in each gambling establishment, the same as those limits in any ordinance or resolutions that formerly applied to the gambling establishment. Where this article refers to an expansion of gaming as compared to that permitted on January 1, 1996, for the purposes of this section, that reference shall be to the ordinance or resolutions that

governed the gambling establishment as of that date.
