How we counted
We joined 2025 Salt Lake County assessor records to county address points inside the mapped Cottonwood Heights boundary, using one address per parcel and preferring the primary address. We counted parcels with housing units and a valid construction year; two invalid years were excluded.
10,422 ÷ 11,157 = 93.41%. Parcels are not individual apartments or people. A construction year does not tell us which plumbing has since been replaced.
