An ADU, or Accessory Dwelling Unit, is a secondary housing unit built on the same property as a primary residence. It may be attached to the home, detached in the backyard, or created through a garage conversion.

Garage Conversions
One of the Most Practical ADU Options
Garage conversions represent one of the most prevalent methods for creating an ADU. Since garages are already constructed with a frame, foundation, and roof, they serve as a practical base for increasing livable space. Many homeowners in San Tan Valley opt for garage conversions because they utilize existing square footage, often incur lower costs than building a separate structure, can be completed more quickly than new constructions, and function well as guest suites or rental spaces. However, garages were not originally designed for living purposes, and upgrades to insulation, plumbing, ventilation, and electrical systems are usually necessary. Stronghold manages these enhancements to ensure the new space complies with residential building codes and feels like a natural extension of the home.
