RTC § 3791.3

Whenever property has been tax defaulted for five years or more, or three years or more in the case of nonresidential commercial property, as defined in Section 3691, in an applicable county, whether or not the property is subject to or has been sold or deeded for taxes to a taxing agency other than the state, the state, county, any revenue district the taxes of which on the property are collected by county officers, or a redevelopment agency created pursuant to the California Community Redevelopment Law, may purchase the property or any part thereof, including any right-of-way or other easement, pursuant to this chapter. A redevelopment agency, however, may only purchase this tax-defaulted property located within a designated survey area.
