The B-625 is the model that most consistently matches what clients imagine when they say they want to build an ADU. It’s large enough to live in comfortably long-term but doesn’t push against the size limits of most Dane County municipalities (Madison’s ADU size limit is effectively capped at the primary home’s size). At this square footage, it rents at the top of the 1-bedroom range in Madison — typically $1,400–$1,600/month. The build cost runs higher than the compact models, but the rental yield is strong and the property value contribution is meaningful.
Rental income at top of market rate, long-term family occupancy, aging parents who want a genuinely comfortable independent home.
