Housing Age Profile
Because the majority of Rosendale's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1970 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Rosendale were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Rosendale Homeowners
Given current Rosendale valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.

Lead Exposure Risk for Children in Rosendale
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Routinely in Rosendale, where 56% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
