ADUs vs. Tiny Homes, Modular & Manufactured Housing

- How California housing laws and Accessory Dwelling Unit (ADU) rules interact with Tiny Homes, THOWs, Modular Housing, Manufactured Homes, Mobile Homes, Park Model Recreational Vehicles, Appendix Q, Emergency Housing, and more!
I was on a panel with two experts from the HCD (Housing & Community Development) and they get into the detail on what you can use to build an ADU in California.
Greg Nickless, Housing Policy Analyst
ADU Specialist
John Westfall, Codes and Standards
Building Code specialist
Greg talks about what ADU rules say at the state level. In the state rules, ADUs can either be manufactured housing (which is federally approved according to the national building code for manufactured housing) or they can be built to local building code under Title 24. Local jurisdictions can then allow for greater flexibility by allowing Movable Tiny Homes, RVs, Trailers, and other forms of housing to be permitted as ADUs if they choose to.
John then goes through a lot of the details on what each of these options entails. What is a THOW? What is a manufactured house? Does modular mean anything according to the building code? What is decided at the federal level, the state level, and the local level? What insignia do you look for on motorized homes?

This was really an amazing discussion and like Ryan said, it was wonderful having Gregg and John provide there insight. Great editing as always!
Ryan, Just watched this again. August 26th 2023 10:00 Am - This subject is my expertise and I’ve been in the industry of manufactured homes and foundations for over 20 years, 30+years in construction. I work with Dan Fitzpatrick who wrote the THOW statues for the local California municipalities such as LA, San Jose, San Diego, Fresno and many more. We work with HCD (John) regularly in this arena and we are moving forward on the new ICC standard for “Movable Tiny Houses” I’d really like to see you do a follow up on this subject and Dan and I would be happy to do a zoom with you. I have so much more to share with you and this video resonates with me 1000%. Let’s communicate and open up this incredible booming opportunity to combat the California Housing Crisis. Thanks !
That could be fun. Email me ryan@how-to-adu.com- do you have examples of people living in permitted thows in CA? I want to show this stuff actually being used safely.
What would the cost difference be for a 260-300sq ft tiny house vs a permitted ADU in the city of Los Angeles? Would the city reassess my property value and raise taxes if doing permitted ADU ? Maybe it’s better to do un permitted 300 Sq ft and hope for the best but I’ve seen really nice tiny house on wheels in that size for about $80k.
Did you ever do your follow-up to getting the city to use SB9 state guidelines? San Diego is still dragging its feet on guidance for Sb9.
Not yet, and I actually have a confession I need to record about that. But will update soon.
I’m trying to find the cheapest way to put one or two units on my property so I can gain some passive rental income and also help out people they need housing. It sounds like “ itle 25 manufactured home” is the easiest/ most affordable way to go? Is this correct? I don’t even know what that is, is that just considered a mobile home?
Manufactured housing (title 25, and what used to be referred to as mobile homes pretty commonly) is often a much cheaper to generate rental income. That said, financing options and market rate rental might both be more challenging with this option compared to title 24 construction. It really depends on a lot of variables!
But yeah, talk to a manufactured housing dealer in your area (I work with BAMH in the Bay Area) and you can price out your options.
You can also book a call with me to discuss your specific project: how-to-adu.com/get-started-booking
If you have any carpentry skills, collect the good scrap lumber (and frames if you need one) from these tornado damaged places and build your own! My brotherinlaw built a knockout gorgeous two story cabin doing this. He also took an old pier apart and put the wood on the staircase and bedroom wall, dockeyes still attached, and it is a beautiful, magazine ready cabin! He owes $zero$ on it. But its not for rent!!😊
The first few minutes seems like the regulation is based on mortgage companies?
There are some things driven by safety and building code, and other things driven by the county tax assessor - I didn't realize how philosophical this would get. 😅
If you add an office attached to your ADU, can you live there? :)
some of the modular's have a cool modern design , tiny homes are heavy ,manufactured homes look like a mobile home on a slab un til the door gets moved from the side still looks like a mobile home
Thanks for the thoughtful comment. I think the specialists in the video are talking more about the legal/compliance aspects of these and not addressing the specific products that are currently popular (or how those products look and feel). And a big takeaway is that "modular" isn't generally a regulated word like "manufactured home" is.
Energy production in the home isn’t a “bell & whistle” extra, in California or anywhere else. Rather, it’s key to both affordability and SURVIVABILITY especially if you live in a state with dumb leadership like Texas, where your state-supplied power could get cut off in peak weather events (hot or cold) which WILL BECOME MORE FREQUENT. A home that is SELF-SUFFICIENT could literally be the difference between life and death.
Intresting..it's best to be educated as much as possible..
Title 25 of what?
California Code of Regulations, govt.westlaw.com/calregs/Browse/Home/California/CaliforniaCodeofRegulations?guid=I0F3B6B60D45311DEB97CF67CD0B99467&originationContext=documenttoc&transitionType=Default&contextData=(sc.Default)
I’m struck by how outdated these guys ideas are about Tiny Home and ADU construction. Both are typically NOT built to Manufactured Home (ie. Mobile Home) standards, but rather to Modular Home standards, which are higher quality, factory-built. And they aren’t just slapped onto concrete blocks. People are doing things like building units on base-isolated foundations or 3D Printing wall segments using UV Rapid-cured cements that are rated more earthquake and fire safe, than typical crappy stick-built homes. Modular building like this IS THE FUTURE, and so loan services, regulations, and permitting needs to play catch-up. QUICKLY.
Thanks for watching and sharing! I haven't met many Tiny Home builders building to either manufactured or modular standards. I see a lot of ANSI actually.
@@HowToADUexactly 💯 %
an ADU beats a tiny home everyday of the week.
You know where I land ;)
But sometimes I talk to people who are just trying to lodge a relative temporarily after a disaster (like the fires in Napa and Sonoma) - sometimes Tiny Homes or trailers or Park Model RVs made a lot of sense in those specific situations. They were available, the insurance would pay for it, etc. So there are lots of specific times I've advised people toward THOWs and motorized. But it's not my general stance by any means!
