Sounds like a great way to import rich people and exploit poor people by capping their level of home value.
Thanks for all that hard work on the house, sorry it's getting repo'd and auctioned. Next time, don't try to make a place to live so high quality!
Property tax should be paid on square footage of the boundaries. Impose a property sales tax with progressive residency penalties or some other extractive mechanism, but have the common decency to let people invest in and improve their own homes.
Sure, Georgism has a lot to recommend it (more or less exclusively taxing land), but that's not happening in the US any time soon.
SF is not going to tax your house more because you went from Home Depot subway tile in the bathroom to Murano hand made glass from Italy, whether you file a permit or not. One of my children just had their house electrical system upgraded from knob&tube to contemporary romex, all under a permit, and I don't believe it will have any impact on their property taxes whatsoever.
If you did in fact add a room or enlarge the building, then it's worth more and will/should be taxed more, no? The taxes represent a small additional part of the total cost of the changes, spread out over years.
California Prop 13 causes some serious market distortions.
Thanks
