Colorado Property Research, Done Right
We built CL Property Search because finding accurate, free Colorado property information should not require navigating six different county portals, paying for a third-party report, or guessing whether the data is current. It still does — but we are working to change that.
Who We Are
CL Property Search is an independent property research site covering all 64 Colorado counties. We are not a government agency, not affiliated with any county assessor, and not a title company. We are a small team of researchers who spend our time manually verifying Colorado property data, monitoring legislative changes, and writing guides that explain how the system actually works — not how it is supposed to work in theory.
Every guide on this site is written by people who have actually searched Colorado property records, filed tax protests, navigated zoning maps, and dealt with the frustrating quirks of 64 different county portal systems. When we say the Larimer County portal uses “Schedule Number” instead of “Parcel Number,” it is because we found that out by searching it ourselves.
What We Provide
Colorado has some of the most publicly accessible property data in the country, but it is spread across 64 separate county systems with different interfaces, different terminology, and different levels of detail. CL Property Search consolidates access to all of it and explains what you are looking at once you find it.
Property Search
Free search tool covering all 64 Colorado counties. Search by address, owner name, or parcel number with links directly to official county portals.
Research Guides
Plain-language explanations of Colorado property tax, records, zoning, and the deed system. Written for homeowners, buyers, and investors — not attorneys.
Verified Data
Every fact we publish is traced to an official Colorado source — C.R.S. statutes, county assessor portals, DOLA publications, or county planning documents.
Our Research Team
Our guides are written and reviewed by the Colorado Property Research Team — a group of independent researchers with backgrounds in real estate, land use, and Colorado county records. We do not use AI to generate facts, and we do not publish claims we cannot trace to an official source.

Lead Research & Editorial
Our core research team covers Colorado property law, assessor records, and county-level zoning regulations. Every guide goes through a review process that includes source verification against official Colorado statutes and county documents before publication.
We have personally tested search portals across all 64 Colorado counties, filed formal records requests, attended county Board of Adjustment hearings, and tracked Colorado property legislation through the General Assembly — including HB24-1152, the 2024 ADU law.
How We Research and Verify
Before any fact goes on this site, it goes through a verification step. Here is what that process looks like:
Primary Source First
We start with official Colorado sources — the Colorado Revised Statutes (C.R.S.), county assessor portals, DOLA publications, and municipal zoning codes. Secondary sources are only used to cross-reference, not as primary evidence.
County Portal Testing
Search tips, portal names, and county-specific details are verified by actually running searches in each county’s system. If a tip does not work in the real portal, it does not go in the guide.
Legislative Monitoring
Colorado property law changes regularly. We monitor the General Assembly, DOLA announcements, and county assessor updates to flag when published information needs to be revised. Pages are date-stamped and reviewed at minimum annually.
Clear Sourcing
Every guide includes a Sources section listing the specific statutes, portals, and official documents behind each major claim. If we cannot cite a source for a fact, we do not publish the fact.
What We Are Not
We want to be specific about this because it matters for how you use the information on this site:
- We are not a government agency or affiliated with any Colorado county assessor, clerk, or planning department.
- We are not attorneys. Nothing on this site is legal advice. For specific legal questions about your property, consult a licensed Colorado attorney.
- We are not a title company. For a formal title search before purchasing real estate, hire a licensed Colorado title company.
- We do not guarantee that county portal data is current or error-free. County assessor records can lag behind real-world changes by several weeks.
Our guides are starting points, not substitutes for professional advice on significant property decisions. When money is on the line, verify with the official county source or a licensed professional.
Why We Built This
Colorado property data is public by law. But “public” has not always meant “easy to find.” Before we built this site, finding basic information about a Colorado property — who owns it, what it is worth for tax purposes, whether it qualifies for the senior exemption, what zoning applies to the backyard you want to build an ADU on — required knowing which of 64 different county systems to check, what each portal calls a “parcel number,” and where the Clerk and Recorder data is separate from the Assessor data.
That information gap costs Colorado residents money. Homeowners who do not know how to check their assessor record miss errors that inflate their property tax bill. Buyers who do not know to check both the Assessor and the Clerk and Recorder miss liens before closing. Investors who do not check zoning before purchasing commercial property discover use restrictions after the fact.
We built CL Property Search to close that gap. Everything here is free, sourced, and written for people who are not property professionals — because most Colorado property owners are not.
