Westridge Eviction Risk: Elevated , Portola Valley

What pushes it up most is rent-regulation exposure at 9.6/10. 59% of renter households cross the 30%-of-income line, well above the San Mateo County average of 44.9%.

Well under the midpoint, economic stress reads 1/10. Running cool, court filing pressure reads 1.4/10.

Food insecurity runs 5.7% against 17.8% nationally. It sits 0.9 points below the San Mateo County average of 7.0. Adults with no health insurance runs 3.3% against 11.3% nationally.

That is riskier than roughly 79% of the 84,120 US census tracts in this model. Only 15% of units are renter-occupied. Rental comparables are thin; price a renewal off the nearest genuine rental sub-market rather than off surrounding sale prices. On the CDC Social Vulnerability Index the tract reads 4.3/10, which tracks how hard a shock lands on the households already here.

Against average income of $250,001, annual rent is just 17%. Statewide the CA average is 7.5, so this tract runs 1.4 points cooler.

Of its three components the socioeconomic standing measure is the least pressured. Poverty sits at 4%, low enough that arrears here usually signal a specific shock rather than a structural income gap.

All figures here are ACS 5-year estimates for this tract, refreshed as the underlying releases land.
