I don't know if it counts exactly as a subsidy, but in some big cities, growth is artificially constrained by "Urban Growth Boundaries". These ordinances reduce the amount of available land for building, and hence inflate real estate prices above what they "should" be by artificially reducing supply. Check out Portland for an example of this. Note that I'm not necessarily arguing against UGB's - I don't think anyone has developed an alternative besides endless suburban sprawl, or naturally restricted land area, as in San Francisco or Manhattan.
