Why Campello needs this specifically
Shared-wall triple-decker construction in Campello means crawlspace or basement contamination in one building section can extend toward an adjoining unit’s foundation area.
Shared sewer laterals in older triple-decker buildings mean a single backup or root intrusion event can flood more than one unit at once, and cross-contamination risk between units is real once black water is standing.
