Wis. Stat. § 707.10: Zoning and other regulation of time-share projects.

(1) Limitations; land use regulation. No zoning or other land use ordinance or regulation may prohibit time-share projects or impose any requirements upon a time-share project which it does not impose upon a physically identical development under a different form of ownership. No provision of a state or local building code may be applied differently to an improvement to real property in a time-share project than would be applied to a similar improvement under a different form of ownership.

(2) Limitations; other regulations. No county, city or other jurisdiction, other than the state, may impose a burden or restriction on a time-share project that is not imposed on all other property of similar character not part of a time-share project.
