Colorado Outdoor Estates Registry
Evergreen and Genesee planning begins with parcel authority, not postal address. Current Jefferson County records make outdoor-project triggers more visible, while the 2026 code and wildfire changes make WUI status, access, defensible space, structure hardening, water, sanitation, and disturbance essential early questions.
Authority path
Is the parcel unincorporated Jefferson County, and which fire, road, water, sanitation, well, septic, and private authorities serve it?
Current local signals
The County states that the 2024 Building Codes, supplements, fee schedule, updated Wildfire Resiliency Code, and new WUI Overlay map apply to permits filed on or after July 1, 2026.
County guidance identifies permits for pools of any size, engineered and permit paths for retaining walls over three feet, access permits for qualifying driveway work, and likely grading review at one-half acre or more of disturbance.
