Overview

What is an ADU?

An ADU is a secondary housing unit located on the same property as your main home. Also known as granny flats, guest houses, or in-law suites, ADUs come in many forms:

  • Detached units in the backyard

  • Attached additions

  • Garage conversions

  • Junior ADUs (JADUs) within the main home

These flexible spaces are perfect for multigenerational living, rental income, or private use like offices and studios.

Why build an ADU?

ADUs are increasingly popular due to:

  • Strong rental demand in many regions

  • Property value increases

  • Mild climates that support year-round building

  • City and state incentives like pre-approved plans and reduced fees

Whether you’re in a bustling metro or a quiet suburb, our team understands zoning laws, setbacks, and lot coverage requirements in your area.
