Dearborn Park Phase I has eight master associations:
- 801 South Plymouth (which is a master association with Terraces, townhouses, and garage associations within it).
- 899 South Plymouth highrise (the retail space, currently divided among three tenants, is just a unit like any other)
- 901 South Plymouth highrise (owns their garage)
- 1115 South Plymouth midrise
- 1145 South Plymouth midrise
- 1169 South Plymouth midrise (each midrise is a master association with two little townhouse groups along State Street).
- Townhouses of Dearborn Park (144 in seven clusters)
- Garden Homes of Dearborn Park (the group I described above)
DP1 also includes The Oaks, a senior rental building owned by Draper & Kramer. There is no master association for the whole compound; the security contract is divided up based on a handshake agreement from the 1980s.
