Before turning raw space into living space, have the scope account for moisture conditions and any needed waterproofing or foundation repairs. Portland’s housing mix includes single-family homes, multifamily homes, and middle housing such as attached townhouses, duplexes, triplexes, and fourplexes, so access, shared conditions, and the existing basement layout can shape the work. A finished basement also requires planning for permits when it becomes living space.
