by
Boulder County Colorado Property Records Navigator

Find Boulder County Parcel Values, Assessment Records and Tax Bills

The Boulder County Assessor determines actual property value, classification, assessed value and exemption status. The County Treasurer calculates the tax from certified values and local mill levies, sends tax notices and collects payments. The Clerk & Recorder maintains deeds, liens, plats and other recorded documents.

This guide explains how to search by address, owner, subdivision, account, parcel or section-township-range; read the 2026 intervening-year valuation; compare school and local-government assessed values; verify taxes payable in 2026; check senior and veteran relief; appeal a determination; and locate recorded deeds or liens.

What Boulder County Property Owners Should Do Now

Real-property appeals to the Assessor closed June 8, 2026. The Assessor must mail Notices of Determination for timely appeals by August 15. Owners who disagree with a determination can submit a written appeal to the Boulder County Board of Equalization by September 15, 2026.
Filed a timely 2026 appeal Watch for the Notice of Determination. The Assessor states that staff cannot provide an appeal status before the notice is mailed.
2025 taxes remain unpaid All normal 2026 payment dates have passed. Search the Treasurer’s live account because interest and post-August fees depend on the payment date.
Senior exemption not yet filed The on-time July 15 deadline has passed, but late 2026 Senior Homestead Exemption applications are accepted through August 15.
2026 is an intervening valuation year: Most unchanged properties retain their 2025 value. A new Notice of Valuation is issued when property condition or classification changed from 2025.
Two different “2026” questions: Taxes being paid during 2026 are generally based on the 2025 tax year. The 2026 assessment will normally appear on the tax notice issued in early 2027.

How Boulder County Values Property for the 2026 Tax Year

Sales Base Period Residential and other market evidence was studied from July 1, 2022 through June 30, 2024.
Time-trended sales are adjusted to the appraisal date.
Appraisal Date The probable market value is estimated as of June 30, 2024.
This appraisal date is used for both the 2025 and 2026 tax years.
Property Condition Date The Assessor values the property as it physically exists on January 1, 2026.
New construction, demolition or classification changes can affect the intervening-year record.
2026 Actual Value Most unchanged properties retain the 2025 actual value.
Changed properties receive an updated 2026 Notice of Valuation.
Comparable-sales evidence: Use sales from the official July 1, 2022–June 30, 2024 base period and the county’s time-trended prices rather than relying only on a later 2025 or 2026 sale.
Current-market misunderstanding: A 2026 property value is not an estimate of what the property would sell for on August 6, 2026. It reflects June 30, 2024 market conditions and the property’s Jan. 1, 2026 physical condition.

Residential school rate

The published assessment rate for school-district taxes is 7.05% for both the 2025 and 2026 tax years.

2025 local-government rate

Residential taxes paid in 2026 use a 6.25% rate for county, city, fire and other local-government districts.

2026 local-government rate

The 2026 tax year, payable in 2027, uses a 6.8% rate after a local-government value reduction equal to 10% of the first $700,000 in residential actual value.

Property category 2025 rate 2026 rate 2026 value adjustment
Residential—school districts 7.05% 7.05% None
Residential—local government 6.25% 6.8% 10% of first $700,000 in actual value
Commercial 27% 25% None
Agricultural 27% 25% None
Business personal property 27% 26% None
Vacant land 27% 26% None
One mill: One mill equals $1 of tax for every $1,000 of assessed value. A parcel can be served by many taxing authorities, so its total mill levy depends on location.
Do not multiply the entire residential value by one rate: Colorado’s current system separates school taxes from local-government taxes and can apply a value adjustment only to the local-government calculation.

Late Assessor appeal: Filing after June 8 can cause the owner to lose further appeal rights. A factual property-description correction does not automatically reopen the ordinary valuation appeal period.
After the BOE: A BOE decision can generally be challenged within 30 days through the Colorado Board of Assessment Appeals, district court or binding arbitration route.

Mailing address versus legal ownership

How to Correct an Owner Name or Mailing Address

Mailing-address change Use Boulder County’s Just Appraised address-change system. The submitted change is sent to both the Assessor and Treasurer.
Simple mailing correction The Assessor can also receive a request containing the account or site address, current mailing address and corrected mailing address.
Owner-name typo Contact the Assessor when the recorded deed is correct but the property database contains a simple clerical error.
Add, remove or replace an owner A deed generally must be recorded with the Clerk & Recorder. An address-change form cannot transfer legal title.
Search the Assessor record. Copy the exact account, parcel, owner, situs address and current mailing address.
Determine whether the issue is address or title. A mailing correction is administrative. An ownership change normally requires a recorded deed.
Submit the correct request. Use Just Appraised for an address update or the Recording Division for a deed.
Keep the confirmation. Save the submitted form, email, deed reception number or recording receipt.
Verify both systems. Recheck the Assessor property record and Treasurer tax account after processing.

Enter a targeted search term. Search grantor or grantee name, subdivision, document type or document number.
Set the recording-date range. Narrow the search when researching a purchase, refinance, lien, release or foreclosure event.
Choose the search scope. Use Search Index Only for indexed fields or Search Index & Full Text to search OCR content as a phrase.
Open the correct document. Match names, document type, reception number, recording date and legal description.
Review the watermarked image. Free watermarked images can be viewed, downloaded and printed from the public portal.
Order a clean or certified copy when required. Non-watermarked and certified copies can be ordered through the portal for the applicable fee.
Search for releases separately. A deed of trust, mortgage or lien does not prove whether a later release was recorded.
Property Alert: Residents can create a free Property Alert account to receive notice when a document matching a registered name is recorded.
Recording does not validate a document: If an instrument meets statutory recording requirements, the Clerk generally must record it. The Recording Division cannot determine whether the filing is fraudulent, legally effective or sufficient to clear title.

Title-specific answers

Boulder County Property Assessor Search and Tax Records FAQs

1. How do I search Boulder County Assessor property records?

Use the official Boulder County Property Search. Enter a property address, owner name, street name, subdivision, Assessor account number, 12-digit parcel number or section-township-range, or zoom to the location and select the parcel on the map.

2. What information appears in a Boulder County property record?

The property profile can show ownership, mailing and situs addresses, account and parcel numbers, legal description, lot size, subdivision, market area, property characteristics, actual values, school and non-school assessed values, estimated taxes, taxing authorities, sales, deeds, zoning, septic, permit, floodplain and survey information.

3. What is the difference between a Boulder County account number and parcel number?

The Assessor account number identifies a taxable property account. The parcel number is a 12-digit number identifying a parcel of land and may not be unique to every building or account associated with that parcel. Verify both when multiple results appear.

4. How is Boulder County property valued for the 2026 tax year?

For 2026, the Assessor values the property as it existed on January 1, 2026 and estimates what it would have sold for on June 30, 2024. Most properties with no condition or classification change retain their 2025 actual value.

5. Why does a Boulder County residential property show two assessed values?

Colorado currently uses separate calculations for school-district taxes and other local-government taxes. For tax year 2025, paid in 2026, residential property uses a 7.05% school assessment rate and a 6.25% local-government assessment rate.

6. When were Boulder County property taxes due in 2026?

Owners choosing two installments owed the first half by March 2, 2026 and the second half by June 15, 2026. Owners choosing one full payment owed it by April 30, 2026. Late payments require the current Treasurer payoff.

7. What are the Boulder County online property-tax payment fees?

The Treasurer currently lists no fee for an online eCheck, a 3.29% credit-card fee with a $5.20 minimum and a 1.33% debit-card fee with a $1.45 minimum. Review the payment screen before authorization.

8. How much is the Boulder County Senior Homestead Exemption?

The exemption removes 50% of the first $200,000 in actual value of a qualifying primary residence, for a maximum exemption of $100,000 in actual value. The late 2026 application deadline is August 15.

9. How do I appeal a Boulder County 2026 property value?

The Assessor appeal period ran from May 1 through June 8, 2026. Timely filers receive a Notice of Determination by August 15. An owner who disagrees with that determination can file a written appeal with the Board of Equalization by September 15, 2026.

10. Where do I search Boulder County deeds and liens?

Use the Boulder County Clerk & Recorder Public Search. Search by grantor or grantee name, subdivision, document type, document number or recording-date range. Free watermarked images are available, and clean or certified copies can be ordered for the applicable fee.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
