About This Model

The C-693 is a single-level 2-bedroom. The step from 1-bedroom to 2-bedroom ADU matters for two specific situations: a couple or parent-and-adult-child who each need their own sleeping space, or a rental situation where a second bedroom significantly expands the tenant pool and the achievable rent. In Madison’s rental market, a 2-bedroom ADU typically commands $300–$600/month more than a comparable 1-bedroom. The C-693 is the most buildable 2-bedroom option on constrained lots because its footprint is closer to the B-series than the larger C models.

Ideal For

Two family members, couple with a child or home office need, rental to maximize tenant count and rent.
