The Zurich Property-Appreciation Offset Act (MAG) and the Property-Appreciation Offset Ordinance (MAV) came into effect on January 1, 2021. In connection with the new legislation, the municipalities of Bülach, Illnau-Effretikon, Wädenswil, Dübendorf, and Kilchberg commissioned EBP to help them establish an implementation framework. The legislation provides a basis for assigning a value to property-owner advantages that arise as a result of official rezoning and zone-expansion measures. The scope of our support included drafting revisions to local building and zoning codes, overseeing public-disclosure processes, and evaluating objections. Our specialists also assessed financial impacts and clarified various technical issues, including those associated with the fund regulations.
