Which San Mateo Peninsula cities does AddressIntel cover?
AddressIntel tracks the full Peninsula corridor, including Atherton, Burlingame, Hillsborough, Menlo Park, Palo Alto, Redwood City, San Carlos, San Mateo, Woodside, and more, with live listings, sales, and permit data for each city.
How does AddressIntel predict teardowns on the Peninsula?
Each property is scored on lot value relative to structure value, building age, and recent neighborhood comps. High land-to-improvement ratios in markets like Atherton and Palo Alto flag the strongest teardown and rebuild candidates.
Where does the Peninsula permit data come from?
Building, addition, and demolition permits are pulled directly from city building-department systems (Accela, eTRAKiT and Tyler EnerGov) and refreshed daily, so you can spot new construction and demolition activity as it is filed. Coverage is per city rather than Peninsula-wide: the cities we ingest are listed on the permit tracker, and each city dashboard says plainly whether we carry that city or link you to its own portal instead.
Can I see developer ROI for Peninsula properties?
Yes. AddressIntel projects per-property developer ROI from land cost, build spec, and local comps, helping you compare opportunities across Peninsula submarkets.
