Idaho Becomes the First State to Adopt the IRC Tiny House Appendix V

Idaho Becomes the First State to Adopt the IRC Tiny House Appendix V

It’s official. Idaho has become the first state to adopt the IRC Tiny House Appendix V! It happened yesterday, June 27th, and the tiny house community is buzzing. This is a huge step forward for everyone who wants to live legally in their tiny home. There is still a lot of work to be done in Idaho, but this is absolutely the best outcome from yesterday’s vote. The vote was unanimous too!

Idaho Adopts Appendix VMacy Miller from has been an essential player in the Idaho adoption process and we want to send out our gratitude for all of her efforts. As I told her yesterday, she’s a ROCK STAR! Macy will be writing an article about the process: what she said to the code board, what worked and what didn’t, and we will share that article with you as soon as it is complete. She told me that she has specific notes that could be reproduced in other locations as well. That will be very helpful for all of you who are interested in helping with the appendix adoption in your state. 

I have been working with several locations as well over the last few months. Here’s a little update on each of those…


Idaho Adopts Appendix VOregon recently passed their version of an adoption process and the governor signed it into law a short time ago. We still have not officially adopted Appendix V, but we have created a motion to do just that. Now we have our eyes on the prize: statewide adoption of Appendix V.


Idaho Adopts Appendix VMaine is using a legislative process to speed up the adoption as well and plans to have the appendix adopted before year’s end.


Idaho Adopts Appendix VI fly out to Massachusetts in September to present to the code development board there. The state’s top building inspector has assured me that we are on target to adopt the appendix in January.


Idaho Adopts Appendix VGeorgia is also seeing the adoption process move forward and they expect to have Appendix V in place before year’s end.


Idaho Adopts Appendix VFinally, I’ve been in touch with the State of New Mexico and they are working towards adoption. In fact, they’re hopeful that they may be able to add a moveable tiny house code as well. Martin Hammer an dI have provided them with the skeleton code appendix we have been working on for moveable tiny houses. Let’s hope they move to adopt it… Now THAT would be something!

Stay tuned for more updates as they come in from states across the country. We will keep you as updated as possible. If you have updates to share with us and the tiny house community in general, please be sure to share them in the comments section below. If you want to get involved with the adoption process in your state, stay tuned for Macy’s article that will give you talking points and other ideas for your own state process.

    I think this is great news. I am a builder of tiny homes on North Carolina. Free Spirit Tiny Homes. I wished my state would hurry up and get on board. It would open doors to our business and for others to enjoy the life style of their desires. Thank You for all your devoted hard work.

      Hi Jeff. It will definitely take longer in some areas of the country. That said, I was not expecting Idaho to be the state to lead the pack, so who knows what’s possible?

    This is amazing news! Macy is a super hero for all the hard work she has put into getting this passed.Thank you!!!

    • Andrew June 29, 2017 at 12:03 pm #

      Absolutely! It was amazing to have her on the team in Kansas City when we first presented our Appendix, and it’s great to see her get this win!

  3. Barbara A Difenderfer June 29, 2017 at 11:07 am #

    I am so excited to hear this! Just wish California would hurry up.

    • ZELDA F WILLIAMS June 29, 2017 at 11:54 am #

      Hi Barbara, I live in California. What’s happening here with tiny houses? You have any links to info I can get started with?

      • Teresa Baker June 29, 2017 at 4:22 pm #

        If you’d like you can subscribe to the Tiny Advocacy Network … we’re LA based but expanding to share information across California. We send out newsletters on achievements and ways to get involved.

        • Andrew June 29, 2017 at 5:46 pm #

          Yes!!! Tessa rocks it you guys. He work with the Tiny Advocacy Network is fantastic. Please connect with her in you are in California, especially Southern Cal. Sorry for not thinking of that earlier.

    • Andrew June 29, 2017 at 12:05 pm #

      I know there is movement happening in California in specific communities, but I don’t know about what’s happening at the State level. I have been busy with my work in other parts of the country. I’d love to hear any updates that you might have.

    Wow! Phenomenal!
    Thank you.

    Good news

  6. Cal Miller June 29, 2017 at 12:11 pm #

    Great news, I recently moved to NC and I am renting a house where I plan to build my tiny house on wheels.
    I wish to be mobile and down size my belongings as well as be self sufficient with energy.

  7. Mary Corl June 29, 2017 at 12:27 pm #

    Hurry up Virginia. I’m waiting!!!

  8. Faith Hazelwood June 29, 2017 at 12:46 pm #

    I’m in South Carolina with my THOW’ s parked in someone’s back yard. (Finally insured by Michael in Oregon.. btw) Yes, I will go to any of the legislature’s and fight for our rights. I’ve already been to City Hall.

    • Andrew June 29, 2017 at 12:51 pm #

      Great! Macy Miller has said she will be preparing a document for people to use to speak to their officials. She wrote down her entire process, so it should be helpful once we see that document. Thanks for your efforts!

  9. Lori June 29, 2017 at 10:02 pm #

    This is fantastic, wonderful news! I hope ALL the states will adopt this within the next year, and an appendix for tiny houses on wheels too. I want a tiny of my own but don’t want to have to worry about being ordered to move it or move out of it because it’s illegal. I’ve been watching the shows, reading the books, and drawing sketch after sketch of floor plans for years. I dream of a tiny retirement…..

  10. Don Dollar July 2, 2017 at 3:48 pm #

    This is great news!!! I will be so happy when when GA. MOVES forward in its thinking for the average person! Please keep me informed. I live in a small backwards town in south Ga.

    • Andrew July 3, 2017 at 10:44 am #

      Hi Don. Georgia is making progress towards adoption. This process tends to be slow, but there is definitely some good movement!

  11. Sherry Bean July 22, 2017 at 8:14 pm #

    Any word on Missouri or any groups or contacts I can connect to here to help with this? We hope to buy land within a year and have small home plus build a tiny home for our autistic son to transition to for life skills to help him live independently successfully.

    • Andrew July 31, 2017 at 9:47 am #

      Hi Sherry. Thanks for asking. I don’t have any news on Missouri right now. You are certainly encouraged to contact the state’s top building official and see if he or she is an advocate or foe. I hope he/she is an ally! Good luck…

    Tiny home is certainly cheaper than building or buying a regular house. But tiny home is not for everyone as well. Previously many obstacles to tiny home on wheels before getting the same treatment. As demand for tiny homes continues to grow, it will depreciate like trailers or other mobile homes. So this is very good news. But if you might have different options, you can try find at; They can always provide the best solution for your home needs. And customer satisfaction has always been their top priority.

  13. Donny August 9, 2017 at 7:37 am #

    Any news about Colorado? We’re going to have two tiny home festivals in two weeks here, but still no place to put your tiny home in the Denver area.

    • Andrew August 9, 2017 at 8:40 am #

      Hi Donny. There has been some positive movement in local jurisdictions, but nothing at the state level that I have heard of. Hopefully they are open to making the move if the right people step in and start the conversation. Perhaps that’s you!? 🙂

      I have been working hard in Colorado since 2012 with zoning departments. I have small rural areas allowing moveable tiny houses. This month have spent hours over the phone with Yampa Valley. They want to move forward. Their biggest concern is water rights and sewage on rented properties. Denver City and County will probably never allow on wheels. I have spent hours with the zoning department. There is a place in Federal Heights that does not have building and zoning codes. Unfortunately most of the land available close to Denver. Golden is close. Lakewood stance has been it’s a complaint based process. If neighbors don’t have a problem there is none. If someone complaints then it’s time for a variance. Covenants in mountain subdivisions are setting minimum square footages to control property values. Meeker has allowed some. I can give you some ideas to place a home but they will be a 60 minute drive to downtown Denver.

    Hi Andrew,

    This is great news! Hopefully, she’ll provide her info soon. My wife and I are interested in tiny house living, but we live in York, PA and we don’t think it’s allowed here or in any of the surrounding areas. We’re new at this, so we don’t know where to start to help with this effort, so we’re reaching out to you to find out what’s going on with PA’s efforts and how we can help. Keep up your great work! Thanks, Dan

    • Andrew September 4, 2017 at 9:57 am #

      Hi Dan. Welcome to the huge world of tiny living! I don’t have any contacts in PA in terms of code adoption, so I can’t help directly. I would suggest that you contact the state’s lead building inspector/department and ask if they have plans to adopt the “Tiny House Appendix” from the 2018 IRC. That will get you started. Once you get an answer, let me know what they say and I may be able to help from there. Good luck!!!

  15. Blake Campbell September 3, 2017 at 3:49 pm #

    Is there a place to find or could I get a copy of the skeleton code you and Martin Hammer provided to New Mexico?

    • Andrew September 4, 2017 at 9:56 am #

      Hi Blake. You can review the code that was approved at The code we are working on with NM is not something we are handing out at this point as it would only cause confusion as we continue to make changes. Once we get to a point where it is ready for release, I will post it to the blog. Thanks for your interest!

  16. Dan September 5, 2017 at 6:11 pm #

    Hi Andrew,

    I spoke to PA’s Bureau of Occupational and Industrial Safety UCC Inspection Manager this morning. He said that PA is using the 2009 IRC. He said in 2011 the legislature decided not to adopt that year’s IRC and he hasn’t seen the 2018 IRC yet. He said the Review Advisory Council (RAC) decides what it will adopt and when. He said that he has no idea if/when they’re going to review 2018 IRC.

    Thanks for your help,


    • Andrew September 8, 2017 at 11:52 am #

      Good to know Dan. You may very well still be able to get the Appendix adopted even WITHOUT the rest of the 2018 code. That’s what happened in Idaho.

  17. Justin September 25, 2017 at 4:04 pm #

    Hi Andrew,
    Thank you for everything you are doing to make Tiny House living an option for millions of people. We are in the early phases of building a tiny house hotel/community outside of Phoenix and appreciate all of the information/experiences you have shared. Looking forward to presenting our case to the city and we couldn’t have done it without all of the work you and your team have done.
    Thank you!

    • Andrew September 25, 2017 at 4:08 pm #

      Hi Justin. Thank you for your kind words. I wish you success in your efforts with your project. Please do keep us posted with your progress. Cheers.
