ADU Floor Plans

Flexible space that works for how you live and build

ADU floor plans (Accessory Dwelling Units) are designed to add independent living space to your property without expanding your main home. These detached units are ideal for extended family, rental income, guest space, or even a place to live while you build your primary home.

At Lexar Homes, ADUs are designed to be practical, comfortable, and built for long-term use. Whether you’re looking to create additional income, support family, or make better use of your land, an ADU offers flexibility that adapts as your needs change.

Is an ADU Right for 
Your Property?

  • You want space for extended family while maintaining privacy
  • You’re looking to create rental income or offset housing costs
  • You need a place to live while building your main home
  • You want flexible space for guests, work, or long-term use

Why Build an ADU?

An ADU can solve multiple needs at once, from creating space for a family to generating income or supporting future plans. These are some of the key ways homeowners use ADU floor plans to get more out of their property:

Maximize Your Property’s Potential

An ADU allows you to add usable living space without expanding your main home. It’s a practical way to make the most of your land while keeping your primary layout intact.

Create Rental Income Opportunities

An ADU can serve as a long-term or short-term rental, helping offset mortgage costs and turn your property into an income-generating asset.

Support Family and Changing Needs

Whether it’s space for aging parents, adult children, or long-term guests, an ADU provides privacy while keeping everyone close.

Live On-Site While You Build

An ADU can act as a temporary residence while your main home is under construction, allowing you to stay on your property and manage the build more easily.

Types of ADUs

Not all ADUs are built the same. The right option depends on your property, your goals, and how you plan to use the space.

detached-ADUs

Detached ADUs

A standalone unit built separately from the main home. This option offers the most privacy and works well for rental income, guest space, or long-term living.

Attached ADUs

An ADU connected to the main home but with a separate entrance and living space. This layout balances independence with proximity, making it a strong option for family use.

above-garage-ADUs

Above-Garage ADUs

A living space built above a garage structure. This is an efficient way to add square footage without taking up additional land area.

prefab-modular-ADUs

Prefab or Modular ADUs

Pre-designed units that are built off-site and installed on your property. These can offer shorter timelines, though customization may be more limited than with a fully custom build.

Start Planning an ADU That Works for Your Property

ADU floor plans offer a flexible way to add space, support family, and create new opportunities on your land. Whether you’re building for now or planning ahead, the right design can help you get more out of your property over time.
