Northglenn FAQ
How many guests can stay at a short-term rental in unincorporated Adams County?
Adams County's Development Standards and Regulations do not currently set a short-term-rental-specific overnight occupancy cap in unincorporated areas. Many Colorado hosts apply a voluntary rule of thumb of two guests per bedroom plus two additional people, but this is not a county ordinance. Building, fire, and property-maintenance codes the county adopts still apply. Confirm any property-specific limits, especially on septic systems, with Adams County Community & Economic Development at 720-523-6800.
Can Adams County limit how many unrelated people stay together?
No. Colorado House Bill 24-1007, the Prohibit Residential Occupancy Limits Act, took effect July 1, 2024 and bars Colorado counties and cities from limiting how many people may occupy a residence based on familial or relationship status. Any occupancy rule a local government adopts must be tied to objective standards such as floor area, bedroom count, or building and fire code requirements. This statewide rule applies in Adams County.
Does Adams County inspect short-term rentals for overcrowding?
Adams County does not run a dedicated short-term-rental inspection program in the unincorporated areas because there is no STR licensing ordinance. Complaints about overcrowding can still be investigated under the building, fire, and property-maintenance codes the county adopts, and septic systems on private wells have separate occupancy-related capacity limits. Call Adams County Community & Economic Development at 720-523-6800 to confirm any case-specific limits.
