The C-800 commands the highest rents of any model in the BTH lineup because it solves the one friction point in 2-bedroom rentals: the shared bathroom. In Madison’s rental market, a 2-bed/2-bath unit at 800 square feet with a private entrance is genuinely scarce. Most apartments at this size are in multi-unit buildings with shared hallways and no private outdoor access. The C-800 ADU competes directly against apartment units costing $2,000+/month and wins on privacy and character. Note: at 800 square feet, this model sits at or near the ADU size cap in some Dane County municipalities. Confirm eligibility at your address.
