Whether you’re creating rental income, housing family members, or expanding usable space, ADU kits offer flexibility, efficiency, and long-term return on investment.

Complete Backyard Dwelling Solutions in One Kit

Our collection includes a wide range of backyard cottage packages, accessory dwelling unit systems, and secondary suite kits designed to meet modern living standards. These kits function beautifully as in-law suite modules, granny flat building kits, or prefabricated guest house shells, offering independence while staying close to the main home.

Popular configurations include:

  • Detached residential kits for private, standalone living

  • Garden suite assemblies for compact or landscaped yards

ADU Kits FAQs

1. Will an ADU kit increase my property taxes?

Yes, but typically only for the added value of the new structure. In 2026, most jurisdictions do not reassess your primary home’s value when you add an ADU. Instead, a "blended assessment" is performed, where your taxes increase based on the construction cost or market value of the ADU Kits once completed. This is often offset by the significant boost to your total property resale value.

2. How do I handle utilities like water and power for an ADU?

Most ADU Kits are designed to "piggyback" off your primary home’s existing utility meters. You will typically run trenching for sewer, water, and electrical lines from the main house to the backyard unit. However, if you plan to use the space as a long-term rental, you might consider installing separate "sub-meters" so tenants can pay for their own usage directly.

3. Are ADU kits compliant with local zoning laws?

While ADU Kits are designed to meet general national building codes, "zoning" is a local matter. Laws regarding setbacks (how far the unit must be from your fence), maximum height, and parking requirements vary by city. The good news? Many 2026 kits come with "permit-ready" architectural plans that have been pre-checked for common regional requirements to speed up the approval process.

4. Can I build an ADU kit if I have a small backyard?

Absolutely. There are "Micro-ADU" designs specifically engineered for tight urban lots. As long as you can maintain the required fire-safety setbacks (usually 4 feet from rear and side property lines), you can often fit a studio or one-bedroom unit. Many homeowners choose "L-shaped" or "narrow-profile" ADU Kits to wrap around existing landscaping or trees.

5. What is the difference between an ADU and a "Junior" ADU (JADU)?

An ADU is a completely independent living space (detached or attached) with its own kitchen and bathroom. A Junior ADU (JADU) is smaller (under 500 sq. ft.), must be contained within the walls of an existing residence (like a garage or basement conversion), and can sometimes share a bathroom with the main house. Standard ADU Kits are usually for detached structures, providing maximum privacy for both parties.
