Half Moon Bay Building Permits: Where to Search
AddressIntel does not track Half Moon Bay building permits. We ingest building-department records daily from the San Mateo County and South Bay cities on our permit tracker, and Half Moon Bay is not one of them, so the city's own permit records (Half Moon Bay Building Division, linked below) remain the authoritative source for filings there. What we can bring to a Half Moon Bay deal is the surrounding market: permits from the cities we do cover, plus teardown and ROI scoring across the Peninsula.

The free weekly Peninsula Plays brief
The week's best teardown and spec-build plays across the Peninsula, with the developer ROI worked out from permits, parcels, and sold comps. One email a week, no spam.
Why Developers Target Half Moon Bay
Across the Peninsula, older and smaller homes on large lots are being demolished to build luxury spec homes, and Half Moon Bay shares the housing stock that drives it. AddressIntel's algorithm identifies those aging properties from Floor Area Ratio (FAR), recent neighborhood comps, and permit velocity, in the San Mateo County cities we ingest. It does not run on Half Moon Bay, because we do not hold Half Moon Bay permits or listings to run it on.

Half Moon Bay & San Mateo County Building Permits
Where Half Moon Bay permits actually live: Half Moon Bay Building Division (Cloudpermit). AddressIntel does not ingest Half Moon Bay, so that is the system of record, not this page.
For a Half Moon Bay building permit or demolition filing, go to the city directly: Half Moon Bay Building Division (Cloudpermit) holds the record, and we do not mirror it. AddressIntel's San Mateo County building permits dataset covers the cities listed on our permit tracker, which does not currently include Half Moon Bay. That dataset is still the fastest way to read the San Mateo County market a Half Moon Bay project competes in, and every filing in it is scored for developer ROI and teardown potential.

Half Moon Bay Teardown & Permit FAQ
How many teardown opportunities are there in Half Moon Bay?
None are being surfaced, and that is a coverage gap rather than a finding about Half Moon Bay. Our teardown scoring reads permit and listing signal for the San Mateo County cities on our permit tracker, and Half Moon Bay is not one of them, so read this as "not measured" rather than "nothing there".
What is the typical developer ROI on a Half Moon Bay teardown?
We do not publish a Half Moon Bay figure, because Half Moon Bay is outside our coverage and we have not measured one. Developer ROI anywhere depends on land cost, build spec, and timeline; our teardown ROI guide walks the residual land value model you would run by hand on a Half Moon Bay lot.
Where can I find recent Half Moon Bay building permits?
From the city itself. Half Moon Bay Building Division is the system of record for Half Moon Bay filings, running Cloudpermit. AddressIntel does not carry Half Moon Bay permits, so we would rather point you at the source than imply we mirror it.
Does AddressIntel track Half Moon Bay permits?
No. We ingest building-department records daily from the San Mateo County and South Bay cities listed on our permit tracker, and Half Moon Bay is not currently among them. What we do publish that bears on a Half Moon Bay project is the surrounding market: permits, sales, and teardown scoring for the cities we do cover, refreshed monthly in the developer report.
