A relatively new way to add more homes is starting to catch on but not without some legal pushback.
Senate Bill 9 is being referred to as the "California Home Act" or the lot-splitting law. The bill is letting single family homeowners split their lot and build up to two homes on each lot.
But SB 9 is running into some roadblocks. A Los Angeles Superior Court judge ruled it unconstitutional earlier this week, even as it's being put into play in the Bay Area.
SB 9 hasn't been used much. Partly because of state bureaucracy and because some residents have pushed back on the idea of lots being divided near their homes.
