Quick overview: homeowners in some areas are concerned that building new “tiny houses” (they give an example of 500 sq ft homes) will drive down home prices in the area. They compare them to mobile homes from a planning standpoint and say that they should only be allowed in specifically zoned areas.
Interested to hear the communities thoughts on this.
Ha just move to California where the government passed an ADU law, meaning anybody can add an accessory dwelling on their lot for "more housing".
No need to have parking requirements. Whee!!
The state law is the rule until local gov'ts (county/city) establish their own rules/laws/standards. CA is heavy on local regulations. When I was there, before I built a house, I had to present plans in front of a local board, they met once a month. While at the board meeting, I saw owners of a gas station return each month for 5 months just to get approval to "reduce" signage. The board had control over the height and color of your house and much more. It is heavily regulated - they protect rich knit picky types. They don't want perceived poor people renting out the shed or moving a shed/house into someone's backyard. If you know CA, you know that where people most want to put tiny homes, they ultimately won't be able. Local gov'ts might allow them, but if they do, they'll discourage it by setting a strict standard to electric, plumbing, sewer, easement, height, size, color, you name it, it there will be a rule.
It is nice thinking about adding tiny homes to backyards, but when neighborhoods are planned, the sewer is planned for the number of homes in the original plan, the storm sewers too and if when adding tiny homes, concrete is added to the space, that means more runoff into sewers which means during heavy rains, neighborhoods flood, because the neighborhood now exceeds original specs.
A neighborhood in England 30 years ago was built with just 1 concrete pad for a car, the front yards were small, but as more and more people bought cars, people concreted over their yard for the additional cars, as a result, storm drains couldn't handle the runoff, major flooding thereafter.
Parking can be made an issue by the locals.
The CA state law has limited the changes that local governments can make. Especially related to parking, if the house is within 1/2 mile of public transit.
They can make laws related to size of the unit. These are "accessory" units, so generally sewer, etc do not apply. Fun times.
I assume that PUDs are exempt because they are already "multi-family housing" with their own set of rules.
alameda county, california doesn't appear to be fun times - some of the regulation listed below. they are defining these as actual buildings with foundations that meet building codes so tiny house on wheels won't cut it. i didn't dig very deep, because i know local gov'ts in california especially where it is already crowded and where people most want to live will do all they can to discourage 2 homes on the same lot. i also read that the county has to issue a permit, but in neighborhoods with HOAs, a dispute is between the homeowner and the HOA so basically, the judge will rule in accordance with HOA rules which will likely be updated with the support of the community to prohibit these structures.
