Counts are permits issued per calendar month as Denver publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Housing law — Colorado

HB24-1313 (2024) requires qualifying transit-oriented communities to plan for greater housing density near rail and frequent-bus corridors, rather than imposing a statewide duplex mandate.
