Summit County Colorado Property Search
To search Summit County property records, use the tool below by owner name, parcel number, or property address.

It has about 30,428 residential and 2,489 commercial properties and an effective 2025 property tax rate of around 0.32%. Records are kept by the Summit County Assessor in Breckenridge, the county seat.

How Property Is Assessed in Summit County
The Summit County Assessor values residential, commercial, and land parcels, with a full reappraisal in odd-numbered years. Because the county’s real estate is spread across four separate ski-resort base areas plus the towns around Dillon Reservoir, values vary enormously between neighborhoods — a condo near a lift can carry a very different assessment than a similar-sized home a few miles away in a non-resort area. Our guide covers how resort county properties are taxed.
Each property has a unique parcel number, which is the fastest and most accurate way to pull up ownership, land size, building details, and tax records.

Exemptions & Tax Relief
Homeowners 65 or older who have owned and lived in their home for 10 consecutive years can have 50% of the first $200,000 of value exempted. Apply with the Assessor. See the Colorado senior property tax break.
Veterans with a 100% permanent service-connected disability get the same 50% exemption on the first $200,000, regardless of age. Surviving spouses may qualify. Check veteran exemption eligibility in Colorado.
Summit County has a very high share of vacation homes and short-term rentals near its four resorts. Exemptions generally require the property to be your primary residence, so many resort-area owners won’t qualify — confirm your classification with the Assessor.
