What is a CDU, and can I have one on my property?

A Caretaker Dwelling Unit (CDU) is a separate dwelling unit that is accessory to a principal dwelling or other principal use on the same property.  A CDU  is deed restricted to occupancy by qualified residents, as defined in the Aspen/Pitkin County Housing Authority Guidelines, or occupancy by immediate family, defined as “a person related by blood or marriage who is a first cousin (or closer relative) and his or her children.”

CDU must be listed as an allowed or special review use in the zone district.  Refer to Sec. 4-20 Table 4-1.

CDU restrictions are found in Sec. 4-30-50(e) and 6-30-40(c).  Restrictions include, but are not limited to:

  • Maximum of 700 (lots or parcels < 30,000 sq. ft.) or 1,000 (lots or parcels > 30,000 sq. ft.) net livable square feet

  • The floor area of a CDU is included in the total allowed floor area for the lot or parcel. 

  • A CDU is not required to be rented, but if rented, it must be for a term of not less than 6 months.
