Living in Westridge

Within the already-private character of Portola Valley, Westridge occupies the most elevated and secluded tier. This is the part of PV where the road narrows, the canopy thickens, and the sense of separation from the valley floor becomes absolute. Westridge parcels typically run 1 to 5 acres, many bordering open space directly, with ridge-line and Bay views that are genuinely stunning on clear days — a full panorama from the San Mateo Bridge south to the Santa Cruz Mountains, with the Bay flatlands spread like a map 600 to 800 feet below.

The neighborhood doesn't announce itself. There are no neighborhood signs, no commercial intersections, no through-traffic. The streets — Westridge Drive and its connecting lanes — serve residents only. Buyers who find Westridge are usually looking for exactly this: the upper end of the peninsula's hillside market, where the view and the acreage are the primary value, and the house is designed to disappear into the landscape rather than dominate it.

Schools

Portola Valley School District: Corte Madera School (K-8). Woodside High School (Sequoia Union HSD). Among the smallest and most community-oriented school settings on the Peninsula.

Lifestyle

Ridge and Bay views, 1-5 acre parcels, equestrian trail access, direct open space adjacency. No commercial uses within the neighborhood. Complete privacy from adjacent properties. Well and septic common.

Price Ranges

$4M-$8M for standard estates on 1-2 acres. Exceptional view parcels or new construction: $8M-$15M+. Price per acre reflects view, trail access, and privacy. Insurance costs are a real budget line item.

Westridge Neighborhoods

Distinct residential areas within Westridge, each with its own character, lot patterns, and market dynamics.

Frequently Asked Questions about Westridge

What is the transfer tax in Westridge, Santa Clara County?
Santa Clara County charges a base transfer tax of $1.10 per $1,000 of consideration. The county's largest cities (San Jose, Mountain View, Palo Alto) impose additional municipal transfer taxes — confirm the rate that applies to Westridge with escrow.
What disclosures are required when selling a home in Westridge?
California requires Transfer Disclosure Statement, Natural Hazard Disclosure, lead-based paint (pre-1978), water-conserving plumbing fixtures, and smoke and carbon monoxide alarm certifications. Santa Clara County properties may also need to comply with local supplemental disclosures depending on the city.
What is the difference between median and average home price in Westridge?
Median price is the middle number when all sale prices are sorted — half of homes sold above, half below. It resists distortion from a few very expensive sales. Average price is the arithmetic mean and can be skewed upward by individual high-end transactions. Median is the more reliable indicator of typical Westridge home pricing.
