Introduction
A bathroom remodel is more than just a style upgrade—it’s an investment that adds value and comfort to your home. In San Diego, homeowners are upgrading bathrooms not only in their main houses but also inside their Accessory Dwelling Units (ADUs).
For clarity, an ADU (Accessory Dwelling Unit) is a small living space built on the same property as your main home. These units can be used as rentals, guest houses, or even private suites. Learn more here: Accessory Dwelling Unit – Wikipedia.
