Because single family zoning and unit density limits are the single biggest cause of homelessness, plus they pollute the environment by increasing commuting distances, damage housing affordability, infringe on private property rights and cause the very overpopulation they were created to prevent by encouraging large houses with room for too many children; all single family zoning and unit density limits should be repealed and/or banned immediately.   Also occupancy limits that apply to unrelated adults but not equally to large families should be repealed and/or banned as well.
