Building code considerations for constructing ADUs

International Building Code (IBC)When constructing an Accessory Dwelling Unit (ADU) building codes should always be considered first and foremost. However, there are other several challenges and zoning restrictions that you may need to navigate when building a tiny home or ADU.

Building code considerations and zoning laws

Although building codes may vary slightly from one city or county to another, most municipalities follow International Residential Code (IRC) and International Building Code (IBC) standards. These codes set standards for the design, construction, and safety of buildings. They typically cover issues such as foundation requirements, electrical wiring, plumbing, and structural support. Depending on where you live, you may need to hire an architect or engineer to ensure that your tiny home or ADU meets local building codes.

Another issue is whether your property are the residential zoning requirements for a tiny home or ADU. Most cities and towns have zoning laws that dictate what types of structures can be built on a particular piece of land. In some cases, tiny homes and ADUs may be allowed in certain areas, but not in others. It’s important to check with your local zoning office to determine what types of structures are allowed on your property and what permits you’ll need to obtain.

Financing and land ownership

Financing can be a major challenge when building an ADU. Traditional mortgage lenders may not be willing to lend money for these types of unconventional structures. However, if the ADU takes into account the building code considerations for the local municipality it will make obtaining financing much easier. Container homes that meet certain building codes are considered modular housing and may be eligible for FHA or VA financing when reclassified from personal property to real property in conjunction with land ownership. 

If you don’t own the land where you plan to build your tiny home or ADU, you’ll also need to consider whether you have the legal right to do so. In some cases, you may be able to rent or lease land from a private owner or a local government agency. In other cases, you may need to purchase the land outright.

Utility connections

Connecting to utilities such as electricity, water, and sewage can be another challenge when building a tiny home or ADU. Depending on the location of your property, you may need to install a septic system or connect to a public water and sewage system. You’ll also need to consider how you’ll heat and cool your tiny home or ADU.

Vehicle restrictions

In some cases, tiny homes may be classified as recreational vehicles (RVs) rather than traditional houses. This can create challenges when it comes to parking and living in your tiny home full-time. Some cities and towns have laws that restrict where RVs can park or how long they can park in one place. You’ll need to research these laws and make sure you have a legal place to park your tiny home.

On the other hand, container homes are considered modular housing and fall under a different set of guidelines if they are built according to International Building Code standards.

Final Thoughts

Navigating these legal challenges and zoning restrictions can be complex and time-consuming, but it’s worth the effort if you’re committing to building a tiny home or ADU. It’s important to do your research and work with a lawyer or other professional who can help you navigate the process. With careful planning and a little bit of patience, you can build the tiny home or ADU of your dreams.
