What it Really Takes to Build a Tiny House in RI

What are the Options?

There are two types of tiny houses that you can buy or build. The first is a house on wheels; this can be considered an RV. On the other hand, a tiny house with a foundation is considered an accessory dwelling unit, AUD. In Rhode Island, a house built on wheels must be registered as an RV since they are legally considered vehicles instead of buildings. Recently, a state law has been issued; allowing owners of single family homes to build an AUD for senior relatives ages 62 years and older.

Where Can You Live with your Tiny House

When choosing between these options, you may also consider the regulations that come with each. For the RV’s, the regulations are much easier to abide by since you will not have to deal with the zoning and building codes. The only thing that you must be weary about is finding a place to park the RV. These places include a residence that has given you permission to park, a camping site or RV site. When planning on building a tiny house on a foundation, it becomes trickier since you will have to deal with more rules and regulations. These regulations include zoning bylaws and building codes which consider local factors and safety regulations. Additionally, they prohibit you from buying land and building a tiny house on it. Rather, you can only build a secondary unit on a single family house lot. The zoning rules determine the minimum size requirements that your tiny house must be according to the zone that it is located in it. It is known that most cities and counties have a minimum requirement of 1,000 feet for building a home.

Tips on Building a Tiny House

  • Look at the town’s bylaws. Pay attention to the wording, formalities and procedural recommendations. 
  • Network – not only at Town Hall (knowing your Selectmen, Town Planner, Zoning enforcement officials, Planning Board and Clerks) but also the Fire Chief, Police, and regular folk too! 
  • Have details READY (blueprints, preexisting example images, placement plans, building plans etc.) The town asks A LOT OF QUESTIONS!!! 
  • Consider taking a class (as above mentioned, Yestermorrow was really helpful for DIY building advice!) 
  • Be prepared for lots of questioning, answering and follow-up, and try your best to stay positive
