ADU ROI & Rental Potential
A well-designed ADU in Boise typically rents for $1,200 to $1,800 per month, generating $14,000 to $22,000 in annual income. With build costs often ranging from $180,000 to $250,000, many homeowners see a 6–10% annual ROI before factoring in appreciation. Beyond rental income, ADUs also increase overall property equity, often adding 100% or more of their build cost to total home value. That means your investment not only pays you each month but also builds long-term wealth through higher resale potential and stronger asset value.
Every ADU is unique, and cost depends on the details. Your final price is shaped by the design and layout you choose, the conditions of your site (like slope, access, and utility connections), and the level of finishes you want inside and out. A simple, well-planned design on a flat lot with standard materials will always cost less than a fully custom ADU with high-end finishes or challenging site work. At Mode Homes, we help you balance form, function, and budget to build a space that fits your goals.
