Because of prop 13, each new house costs the EXISTING homeowners money. That&#x27;s because the taxes on the new house will never pay for the additional public infrastructure (roads, schools, public safety, etc) to support its residents. So, at some point, there will be &quot;parcel taxes&quot; for a new wing on the school, a new library, and a new fire house, and then &quot;sales surtaxes&quot; for a new overpass, a Bart extension, etc ......
In San Mateo county, this is where most of the opposition comes from.
