The WCLP, however, was against the bill. Especially it sought to organize the opposition, to "piece together a coalition" of scattered local groups (tenants, senior citizens, religion affiliated), together with the California cities with rent control. Accordingly, Santa Monica, Berkeley, and West Hollywood contributed funds to hire a lobbyist. A concession (obtained by negotiation with proponents of the bill) was the 3-year phase-in of 'vacancy decontrol'. Yet the capitol consensus was that Costa–Hawkins was a "done deal" and the opposition a "last gasp". The passage of Costa Hawkins into law was seen as a rollback of some tenant advantages. Rent control advocates became uneasy at the challenge to their victories of the 1970s and 1980s.
