Do these California laws (or other laws in CA) address restrictive covenants that would prohibit duplexes in a neighborhood regardless of city zoning? You often hear about how Houston, for example, "doesn't have zoning", but a huge fraction of new housing in Texas (Houston and elsewhere) is in planned neighborhoods covered by restrictive covenants that prohibit all sorts of things. In those neighborhoods, it's unlikely that anyone would be able to tear down a single family house and build a duplex on the lot. (Or even paint the existing house a different color without approval of the HOA board.)
