Garage Conversions
One of the Most Practical ADU Options
Garage conversions rank among the most popular methods to establish an ADU. Existing garages come with a structure, a foundation, and a roof, making them a practical option for adding livable space. Residents near Gilbert frequently opt for garage conversions, as they utilize current square footage, often incur lower costs than building a new detached structure, can be completed more swiftly, and serve well as guest suites or rental spaces. However, garages are not originally designed for living purposes. Improvements in insulation, plumbing, ventilation, and electrical systems are typically necessary. Stronghold addresses these upgrades to ensure the finished space complies with residential codes and feels like a natural extension of your home.
