What this counts
Developer parcels, in plain words
Single-family lots where the county values the land at 70% or more of the whole, so the house adds little: teardown, rebuild and infill ground, with each lot’s size (and its zoning in Boulder County and Broomfield). Held 10 years or more. Most valuable land first. Boulder, Larimer, Weld, Adams, Jefferson, Broomfield and Eagle counties.

Questions
Developer parcels in Boulder, answered
How many developer parcels are in Boulder?
41, read October 16, 2026.
What does the Developer trade look for?
lots where the county says the land is 70%+ of the value. Records: The county assessor’s land and total values, the house and its deeds (each county’s own files: Boulder’s nightly files, Larimer’s public data center, Weld’s and Adams’s data downloads, Jefferson’s and Broomfield’s parcel layers, Eagle’s public extract). Zoning: Boulder County’s zoning districts map, read inside each lot’s outline; Broomfield’s own record.
How was it checked?
Top 12 checked by hand on Oct 16, 2026 against Boulder County’s live records: land and house values, year built and size, lot acreage, the purchase, and the zone at the lot’s center, 12 of 12 each. Other counties, Oct 18, 2026: 12 drawn per county (all of them where fewer) against the county’s live record, land value, total value, year built and size: Weld 9 of 9, Adams 10 of 12 (2 a dollar apart), Jefferson 11 of 12 (one lot’s larger house is its second structure), Broomfield 1 of 1. Larimer’s and Eagle’s live records sit behind a disclaimer or a sign-in page, so they were not checked live.
Does a match mean the owner will sell?
No. A match is a recorded fact that fits the trade. Nothing here predicts a sale.
