Colorado GIS, zoning, parcel and land-research resources
Start with Colorado's statewide parcel system, identify the authority that controls the land, and carry every finding or unanswered question into one Property Review.
Statewide parcel start
Colorado's public-parcel map is a statewide starting point, but it currently includes 44 of 64 counties. County records, deeds, plats and surveys control the underlying facts.
Authority must be confirmed
County geography alone does not prove who controls zoning or permitting. Cities, tribes, state and federal land can follow different rules.
OWTS permitting is local
Counties and local public-health agencies permit most on-site wastewater systems. Confirm the responsible office and current requirements.
Water and split estates
Water rights, well records, legal access, surface ownership and mineral interests require separate evidence and documents.
