Building an Accessory Dwelling Unit (ADU) represents a significant investment in your property’s future. Think of it as adding a miniature home to your existing property – complete with all the systems, finishes, and functionality of a standard house, just in a more compact package. Let’s explore the real costs involved in bringing your ADU vision to life.
Understanding ADU Costs: The Big Picture
When we talk about ADU costs, we’re looking at a total investment typically ranging from $200 to $400 per square foot in 2024. For a 600-square-foot ADU, this translates to approximately $120,000 to $240,000. However, these numbers tell only part of the story – much like buying a car, the final price depends on your chosen features, materials, and local market conditions.
