26. 520.010 Purpose
The purpose of the Accessory Dwelling Unit (ADU) Program is to promote the long-
standing community goal of socially, economically, and environmentally responsible
development patterns which balance Aspen the resort and Aspen the community.
Aspen values balanced neighborhoods and a sense of commonality between working
residents and part-time residents. ADUs represent viable housing opportunities for
working residents and allow employees to live within the fabric of the community
without their housing being easily identifiable as "employee housing." ADUs also
help to address the affects of existing homes, which have provided workforce
housing, being significantly redeveloped, often as second homes.
ADUs support local Aspen businesses by providing an employee base within the
town and providing a critical mass of local residents importantto preserving Aspen's
character. ADUs allow second homeowners the opportunity to hire an on-site
caretaker to maintain their property in their absence. Increased employee housing
Ordinance No. 46, Series of2001
Page 2
opportunities in close proximity to employment and recreation centers is also an
environmentally preferred land use pattern, which reduces automobile reliance.
Detached ADU's emulate a historic development pattern and maximize the privacy
and livability of both the ADU and the primary unit. Detached ADU's are more
likely to be occupied by a local working resident, furthering a community goal of
housing the workforce.
To the extent Aspen desires detached Accessory Dwelling Units which provide viable
and livable housing opportunities to local working residents, detached ADU's qualify
existing vacant lots of record and significant redevelopment of existing homes for an
exemption from the Growth Management Quota System. In addition, detached
ADU's deed restricted as "For Sale" units, according to the AspenlPitkin County
Housing Authority Guidelines, as amended, and sold according to the procedures
established in the Guidelines provide for certain Floor Area incentives.
26. 520.020 General
An Accessory Dwelling Unit, or ADU, is a separate dwelling unit incidental and
subordinate in size and character to the primary residence and located on the same
parcel or on a contiguous lot under the same ownership. A primary residence may
have no more than one ADU. An ADU may not be accessory to another ADU. A
detached ADU may only be conveyed separate from the primary residence as a "For
Sale" Affordable Housing unit to a qualified purchaser pursuant the Aspen/Pitkin
County Housing Authority Guidelines, as amended. An ADU shall not be
considered a unit of density with regard to zoning requirements. Accessory dwelling
units shall not be used to obtain points in the affordable housing category of the
Growth Management Quota System (GMQS). Accessory dwelling units also may not
be used to meet the requirements of Chapter 26.530 "Residential Multi-Family
Housing Replacement Program." All ADUs shall be developed in conformance with
this Section.

The Community Development Director, in accordance with the procedures, standards,
and limitations of this Chapter and of Common Development Review Procedures,
