Frequently asked questions

How many parcels are there in Jefferson County, Colorado?

Land Owl maps 243,005 parcel boundaries in Jefferson County, Colorado, an average of 2 acres of county land per parcel. Parcel counts move as land is split and merged, so the county assessor's own figure is the one of record.

Is this parcel map free to use?

Yes. This map is free to view. A free Land Owl account unlocks the other data layers, parcel boundaries and ownership records.

Where does this data come from?

Land Owl compiles parcel boundaries and assessment records from county assessor and GIS offices and matches them into one national layer. Counties publish on their own schedules, so a recent split, merger or sale may not have reached the public record yet. The county's own records are authoritative.

Is the owner's name shown on this map?

Not on this page. Ownership records, mailing addresses and assessed values are in the Land Owl app behind a free account.
