Housing Age Profile

Viewed through the lens of construction era, Fellows is predominantly an older city - a median build year of 1951 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (51%) 1970–1986 (32%) Post-1986 (17%)

Over half of homes in Fellows were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Fellows: Remediation Cost in Perspective

How much of a Fellows home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.

Remediation costs in Fellows are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 76% below the California average.

Protecting Children from Lead in Fellows

Homes Built Before 1986

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.

Pulling a tap sample fills the gap that utility data cannot close, particularly here where 83% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Fellows.
