Types of ADUs We Build

At True Built Home, our ADU plans are designed to fit a variety of property sizes and family needs. Some of the most popular styles we build include:

• Small One-Bedroom ADUs
  Perfect for guest suites, rental income, or independent living, these efficient layouts maximize comfort in a compact footprint.

• ADUs with a Porch
  Many of our smaller ADUs include a welcoming porch, adding outdoor living space and curb appeal.

• ADUs with a Garage
  Combine parking and living space in one design. These plans provide a full living unit alongside a garage for storage or vehicles.

• Two-Bedroom ADUs
  Slightly larger layouts with two bedrooms, ideal for families, multigenerational living, or long-term rentals.

• Two-Story ADUs
  For properties with limited lot space, a two-story ADU provides extra square footage without expanding the footprint.
