County offices

County notes

• •Broomfield is a consolidated city and county, so a single municipal government runs both the city and the county treasurer functions. The Treasurer listed on the office page is Waishing Chiem, reachable at treasurer@broomfield.org, phone 303-464-5810, fax 303-464-5105.
• •The city website states that in Broomfield the County Treasurer functions are split between the finance director (investments and reconciliation) and the revenue manager, with the treasurer handling billing, collection, and distribution of property taxes.
• •The county has posted the 2026 sale for November 4, 2026 at 9 a.m. in City Council Chambers, with the 2026 delinquent list published on the county site. Confirm the date and any changes with the Treasurer's Office before attending.
• •City and county employees and their immediate families are barred from purchasing tax liens at the sale.
• •The county publishes the full delinquent list as an on page public notice rather than a downloadable spreadsheet, with parcel number, owner, legal description (subdivision, lot and block), and total due for each item.
• •Third party tax sale data sites republish Broomfield listings, but none of them conduct this auction. Bids are only accepted in person in Council Chambers on sale day.

Redemption

Redemption may be made at any time before a treasurer's deed is executed, so the practical window runs past the three-year mark and into the Article 11.5 process. Once a deed application is pending, the owner must file an intent to redeem with the treasurer no later than seven calendar days before the scheduled public auction, then pay the amount on the redemption statement while it is in effect, and must redeem the entire property. The auction itself is set 30 to 60 calendar days after the treasurer mails the notice of public auction. A separate rule lets an owner who was under a legal disability when a tax deed was executed under Article 11 redeem within nine years of the deed being recorded, at 15 percent per year plus the present value of any improvements.C.R.S. 39-12-103 - Redemption made, interestC.R.S. 39-12-103Verified Oct 12, 2026

Deed deposit

The treasurer may require the applying lawful holder to deposit up to one thousand dollars plus statutory fees when the application is accepted, applied against the treasurer's fees and costs, and all Article 11.5 fees and costs are chargeable as additional amounts owing under the certificate of purchase. A third-party winner may be charged up to three hundred dollars for processing. The statute sets no bidder deposit percentage, so payment terms come from the treasurer's written auction policies.C.R.S. 39-11.5-102 - Lawful holder, application for treasurer's deed, feeC.R.S. 39-11.5-102Verified Oct 12, 2026

Surplus proceeds

Junior lienors whose liens were recorded before the application for treasurer's deed may file a claim for overbid money within eight business days after the auction. Between the ninth and fifteenth business day the overbid is paid to them in order of recording priority, each up to the unpaid lien plus fees and costs, and whatever remains goes to the property owner. The treasurer mails the owner a notice within thirty days after the claim period ends. Unclaimed overbid stays in escrow for two years without interest to the claimant. Amounts under twenty-five dollars left unclaimed for six months go to the county general fund, and larger amounts left unclaimed for two years go to the state treasurer as unclaimed property. An agreement to pay someone to recover an unclaimed overbid is enforceable only if the fee is capped at ten percent and the agreement is made at least two years after the transfer.C.R.S. 39-11.5-112 - Treatment of overbid, agreement to assist in recovery of overbidC.R.S. 39-11.5-112Verified Oct 12, 2026
