Multifamily in South Hill, WA
South Hill is an active multifamily residential construction market within the Washington multifamily residential landscape. The local climate is a primary MEP engineering variable for South Hill multifamily projects: unit HVAC sizing, corridor ventilation, and domestic hot water loads all shift with local design conditions, and mid-rise buildings must balance ASHRAE 90.1 or IECC energy compliance against first cost. Garden-style apartments, mid-rise podium buildings, townhome communities, and build-to-rent developments are the primary growth drivers across the South Hill metro.
