Hawaii is the next Big Wave for Tiny Houses

Here's the latest links to the House Bills for 2017 pertaining to tiny houses:

HB2 HD ** Newest (specifically for Hawaii island!)




Maui County update 9/01/2016:
Today I received a call from a member of the Maui County building code department who was asking questions about the Maui No Ka Oi magazine article that cam out more then a month ago. He had concerns over some of the comments and suggestions, and he made a few comments that I am concerned about. He said that although tiny houses are exempt from the permit process, that they still need to conform to the building code. I was shocked because I already met with the heads of the building code enforcement and the zoning department, and was given very specific instructions on what "codes" concerned tiny house in Maui County. And those instructions included specifically that the building code did not govern tiny houses because they are on wheels and not affixed to the ground. When I asked the caller what specifically was meant by this the answer was that a 'tiny house must be made to meet all the building codes in the IBC (international building code). Which means they have minimum size requirements, must be connected to sewer and municipal services or solar and catchment. But the sewer component was required. This changes everything if true

First, if the tiny house owner/builder is required to connect the house to sewer, then they must apply for a permit. In order to get a permit for sewer, the house must comply with the building code; therefore defeating the supposed "no permit to construct" a tiny house. This ridiculous red-tape nonsense is brought to you by the bureaucracy which eats it's own like candy. 

Second, if this caller is accurate, then tiny houses must meet all the other building codes, including wiring, gas, solar, materials, minimum square footage, etc. The IBC is clear that the minimum size dwelling for an "efficiency dwelling" is 220 sqft, or 400 square feet for a standard dwelling. The typical tiny house is 160-200 sqft. The code goes on to say that specific rooms/areas such as kitchen, bath and bedrooms must meet certain minimums as well. This means, if true, that the entire concept of tiny houses is not possible in Maui County (see update below for the contradictory statements I have received form Maui County). It's really difficult to get things done when these county departments make matters so complicated and so contradictory that people spend millions of dollars and years of work to accomplish great things only to have their efforts undermined by misinformation, lack of cooperation, questionable practices and a serious lack of defined scope and laws. 

I'm not naming the caller because this situation is being investigated for accuracy, and I'm trying to work with the county to resolve this soon. I'll let you know what happens next. 

Maui County update:
Our friends at the County of Maui zoning and planning department recently told me that the current zoning codes allow tiny houses on lots bigger than 7,500 that contain only one other dwelling (primary dwelling), so long as the tiny house meets the proper setbacks (10 feet away from other structures and 5 feet from boundary fences) and only one tiny house per lot that will serve as an "accessory dwelling" for zoning and setback considerations only. I also spoke with building code enforcement for Maui County, and they said that the building codes do not apply to tiny houses on wheels that are offgrid applications.
If you plan to put a tiny house on your property, please be careful to place it with enough room around it to accommodate the property setbacks and make sure your lot has at least 7,500 square feet and only one primary dwelling. If you have an empty lot, you can put two tiny houses that are at least 10 foot apart and at least 5 feet away from boundary fencing.
Offgrid means solar or wind power, rain catchment and composting toilet. Connecting to county water, sewer and the power grid requires a licensed contractor and a county permit. 100% Offgrid tiny houses do not require a contractor or a permit.
The lot size requirements for zoning "may" be reduced to 5,000 square feet at some point, but no word on if or when that might happen. The main point it to be responsible, be a good neighbor and follow the zoning rules.

When I moved to Maui in 2009, I had no idea affordable housing was in such short linden-lakesupply. There are plenty of empty apartments and houses, but purchasing a home or renting in Hawaii is not a matter of supply and demand, it’s based entirely on what the market will bear. And apparently the bears here have a lot more money than I do.

So ever since then I have been looking to find alternative ways to affordably enjoy paradise. I’ve considered container homes, tree houses and yurts, but when I stumbled upon Tiny Houses I was hooked! Tiny Houses are just what the name implies–they’re smaller than average and have a lot less of everything that a regular sized home has, except more character and less impact on the environment. One striking feature of most Tiny Houses is that they are built on wheeled trailers. This makes most Tiny Houses fit an area of about 8 to 9 feet wide by 16 to 24 feet long (128 to 216 square feet). I wrote an informative article about Tiny Houses not long ago: The Tiny House Movement.


Over the last few months I have been on a journey to determine if Tiny Houses are allowed in Hawaii. It’s been challenging trudging through the red tape. The first obstacle I discovered was that Tiny Houses are not defined in the State of Hawaii as “Tiny Houses”. Initially the building inspector for the County of Maui, Department of Public Works, said that any “dwelling” must be a minimum of 220 square feet which meant that according to the International Building Code (IBC) a Tiny House would probably be defined as an “Efficiency Dwelling” (see details: Efficiency Dwelling vs Tiny Houses). A typical Tiny House is less than 220 square feet so I was bit discouraged and had visions of living in the jungle in a camouflaged, non-compliant Tiny House hidden away from civilization. But I’m not one to give up that easily.


I think Maui County Council member Don Couch would describe me over the next few weeks as “persistent” to get his attention. I presented him with details about the benefits of tiny houses and why I think they are good for the community and he agreed to look into the matter. He and his staff made some phone calls and got some interesting responses. What they initially found out was that the County doesn’t have a definitive answer that is black and white about tiny houses.

Don introduced me to a “research assistant”, code named “Sam”, when we realized we needed help with the research. Over the next month or so Sam uncovered some very interesting facts that could change the course of the Tiny House movement in Hawaii.

Finding a new definition for Tiny Houses in Hawaii


Sam made numerous calls to other state agencies and different municipal departments around the country (anonymously) and here’s what he said:

So far, it sounds like most tiny homes around the country are working around building codes by putting the homes on wheels and registering them with the DMV. According to the Maui DMV Operations Supervisor, a custom built travel trailer would be classified as a “trailer.”

Looking further Sam discovered the actual vehicle code section for “house trailer” which is Hawaii Statewide Traffic Code §291C.

House Trailer: a trailer or semitrailer which is designed, constructed, and equipped as a dwelling place, living abode, or sleeping place (either permanently or temporarily) and is equipped for use as a conveyance on streets and highways.


It’s called a House Trailer!
The Public Works and the Plans Examiner Department said, specifically in reference to recreational vehicles; both said that they would have no jurisdiction over someone living in a recreational vehicle, that the DMV would have jurisdiction because it would be registered with them. The Building Permits Department said they would only become involved if an RV was no longer registered as a vehicle and was then classified as a home (RV was used instead of “house trailer” to save time explaining what that is). So officially, in Hawaii, it’s not a Tiny House or an RV, it’s a “House Trailer”. And it’s perfectly legal!

How to comply with the House Trailer laws in Hawaii*

  • Have a place to build and/or park your Tiny House on private property
  • The trailer it is build upon needs to be legal and must be registered by the DMV
  1. You need to have insurance for the trailer you are going to register
  2. The trailer has to go through an inspection (lights, breakaway brakes, etc.)
  3. The trailer needs to be weighed (the more it weighs the more it costs to register)
  4. It must pass a safety inspection

cypress-24What it means to Hawaii residents is that we have the green light to build or park a Tiny House on private property. These laws can be changed or removed if we don’t police ourselves and be good neighbors and community members. be sure to do any and all electrical to code. Use common sense and be considerate where and how you park your Tiny Home.

What the government will do now:

Revenue generation is a popular topic with government mainly because the coffers are low everywhere and public services are tight.  Property taxes usually pay for a lot of local government like Police and Fire, so whenever a good idea comes around that might reduce the flow into those coffers, local municipalities might want to throw in a few monkey wrenches (red tape and fees).  However, with this solution, and it is a solution to the economic woes for many people across the country, there are already built in regulations and indirect fees.

To build and use one of these Tiny House in Hawaii, you must have a legally licensed trailer.  Those annual fees (licensing and registration) can be fairly high due to the weight of the trailer.  Additional moneys go toward government the traditional way such as property taxes.  Because these House Trailers must be legally parked on private property, the owner of that property already pays taxes.

So expect that local municipalities and counties will attempt to charge fees, add regulation and generally find ways to make things more difficult without a really good, clearly thought out reason or purpose.  Ultimately, when community leaders see the benefits of Tiny Houses, they will see that they reduce the draw on water supplies and the energy grid, lower the impact on the environment, reduce the demand for social services, and provide an alternative to the high cost of traditional housing.

Here are two good reasons why municipalities should PAY people to live in Tiny Houses:

  1. Money:  Saving residents money so they have more to spend in the local economy, and reducing long-term debt.
  2. Environment:  Reduces the environmental footprint (less Space, Water, Energy, Garbage, Waste).

If you’re ready to live in a Tiny House, or you’d like to support this movement, connect with me for upcoming meetings, events and more.

Hawaii Alternative Considerations:

The main reason for all my research here in Hawaii has been due to the IBC (International Building Code) minimum square footage requirements.  Thus the need to build on trailers.   Some solutions suggest that Hawaii should relax of the minimum square footage regulations so that people can create alternative, low carbon footprint dwellings.

I spoke with Michael Janzen of Tiny House Design ( and he mentioned that some other alternatives are already developing in Hawaii recently.

(d) The department of health shall promulgate rules and regulations, pursuant to chapter 91, necessary for the administration of this section. [L 1972, c 48, pt of §2]

I’d like to personally thank…

Special thanks to Sam, who spent tireless hours researching the laws and regulations for me.  He did an amazing job wading through the legal codes, making calls and digging through red tape to find concrete answers to some important questions.

Much Mahalo to County Councilman Don Couch for his ongoing efforts to help find affordable housing alternatives for Maui residents, and all the time he has spent with me sorting out the details of this and several other issues.

July 11, 2014 UPDATE
There always seems to be some obstacle to innovation in Hawaii. Here’s a good example that was sent in from a fan.

This update pertains ONLY to Hawaii County (Island of Hawaii Only):

Hawaii County Code Section 25-4-10. Mobile dwellings.
All mobile dwellings shall conform to the County building code (chapter 5 of this Code), and the Public
Health Housing Code (chapter 2 of the State public health regulations), except:
(1) When parked in a licensed mobile home park; or
(2) When occupied for dwelling or sleeping purposes outside of a licensed mobile home park for less
than thirty days in any one location.
(1996, Ord. No. 96-160, sec. 2; ratified April 6, 1999.)25-4-10

Also, Hawaii County Code 5-71
Section 5-71. Amendments to adopted International Building Code.

The International Building Code, 2006 Edition, adopted and incorporated by reference into this code as provided in section 5-3 of this chapter, shall be subject to the amendments hereinafter set forth.

(1) Amending Section 202. Section 202 is amended by adding the following definitions:

“BUILDING. A building is any structure used or intended for supporting any use or occupancy. The term shall include but not be limited to any structure mounted on wheels such as a trailer, wagon or vehicle which is parked and stationary for any 24-hour period, and is used for business or living purposes; provided, however, that the term shall not include a push cart or push wagon which is readily movable and which does not exceed 25 square feet in area, nor shall the term include a trailer or vehicle, used exclusively for the purpose of selling any commercial product therefrom, which hold a vehicle license and actually travels on public or private streets.

This “currently” applies only to Hawaii County (Big Island).

Possible solutions to consider:

1. Change that law.
2. How can the county prove that the dwelling was occupied for more than 30 days consecutively? Just stay in a hotel for 1 night every 29 days.
3. If you move the house 10 feet every 30 days, then you can live in it forever.
4. Get a Mobile Home Park permit for your property.

What does this all mean for Tiny Houses in Hawaii?
Operation Tiny House is a go (accept on the Big Island apparently)! Feel free to move about Hawaii (in a Tiny House on private property).  If you’re interested in help with a Tiny House or you want to be a part of a Tiny Village on Maui, please contact me.
