Housing Age Profile

Homes on the same street in Rosenhayn can differ: one may keep original pre-1986 plumbing while another has been replumbed, so the 2007 median is only a starting point.

2007
Median Year Built
42%
Pre-1986 (lead solder era; lead paint banned 1978)
42%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (42%) 1970–1986 (0%) Post-1986 (58%)

A significant portion of Rosenhayn's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Protecting Children from Lead in Rosenhayn

42%
Homes Built Before 1986

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
