Homes and townhomes in Harvest Park were designed and intended to be single-family residences. This is covered in Section 8.2 of the CC&Rs which state: “Each Living Unit shall be used only as a single-family residence.” Under the CC&Rs, this means that accessory apartments allowed (meaning a space that is a separate living area that can be separated from the primary home, and a has a separate entrance.) But within a single home, people sharing the living space as a family is allowed. Family has multiple meanings as defined by the city. As of 2025 the definition is as follows in Mapleton City Code 18.08.010:
"FAMILY:
A. Means one of the following groups of individuals, but not more than one group at the same time:
1. An individual living alone; or
2. Two (2) or more people, all of whom are related to one designated occupant of the dwelling by blood, marriage, adoption, or legal guardianship and their foster children and up to two (2) other unrelated persons who do not pay rent; or
3. Up to four (4) related or unrelated individuals who live and cook together as a single housekeeping unit; or
4. Two (2) unrelated individuals and any children of either of them living as a single housekeeping unit.
B. 1. Family includes up to two (2) guests if the guests live and cook together with the family in a single dwelling unit and do not pay rent or give other consideration for the privilege of staying with the family.
2. A "guest" under this subsection B is defined as a person who stays with a family for a period of less than thirty (30) days within any rolling one year period and does not utilize the dwelling as a legal address for any purpose."
Mapleton City also restricts where internal accessory apartments and detached accessory apartments are allowed. This is covered in section 18.84.410 of the city code.
