2545 Union Street

1. March 12, 1970

   A large single-family Victorian house stood on the 68.75-by-137.5-foot lot, a house of some historical significance. Under discretionary review, the City Planning Commission disapproved building permits to replace the house with three four-storey single-family townhouses sold as condominiums, which would have been the first condominium development in an R-1 district in the city.
