California Senate Bill 79 · in effect July 1, 2026

More homes, near transit. What SB 79 does — and what it means for Palo Alto.

California passed a new law (SB 79) that lets developers build taller apartment buildings within a half-mile walk of major train stations — including all three Caltrain stations in Palo Alto. The new rules kick in automatically on July 1, 2026. Cities can shape some details, but they can't say no.

SB 79 in one breath

SB 79 requires every California city to allow taller apartment buildings near busy train stations. The busier the station, the bigger the buildings — and Palo Alto's three Caltrain stations are all in the busiest category (Tier 1). Palo Alto can't block projects that follow the new rules.

Concrete example: today, Palo Alto caps buildings near the University Avenue Caltrain station at around 50 ft. After July 1, 2026, a 7-story apartment building near that station is allowed automatically — no Council vote, no public hearing — as long as the project meets the new rules. All three stations qualify (each gets more than 72 trains every weekday — we did the math).

What's allowed, and where

The closer to the station, the bigger the building the city has to allow:

Distance from station About this many stories Minimum height allowed
Right next to it (within 200 ft) ~9–10 95 ft
Within a ¼-mile walk ~7 75 ft
Within a ½-mile walk ~5–6 65 ft

These are minimums the city must allow, not what every lot will become. Buildings taller than 85 feet have to pay union-scale construction wages.

What “automatic approval” means

A project that follows the state's rules gets approved by city staff working through a checklist — officially, ministerial approval. There's no Council vote, no public hearing, and no environmental lawsuit. If the project checks the boxes, it's approved.
