How We Measure It
AddressIntel scrapes municipal building departments across Silicon Valley every day. For each city we count two leading indicators of redevelopment: demolition permits (the teardown signal) and new-construction permits (the build signal). A city’s activity scoreis simply the sum of those two counts for the cycle, and the ranking below is ordered by that score. It is a measure of where developers are actually pulling permits — not asking prices or listing counts.

What the Ranking Tells Developers
High new-construction counts in cities like San Mateo and Athertonsignal markets where builders are already winning entitlements and dirt is trading for redevelopment — useful both for sourcing comparable spec-build exits and for gauging competition. Demolition-heavy cities flag where the teardown cycle is earliest, which often precedes a wave of new-construction filings a few months out. To turn this into deals, pair the ranking with our teardown ROI model and the live deal screener.
