Boulder County, Colorado Eviction Risk: Moderate

Boulder County carries an average eviction-risk score of 5.8/10 (Moderate), placing it 9th of 64 Colorado counties, where rank 1 is the highest-risk. Only 8 counties statewide are riskier, meaning landlords and investors here face a tighter operating environment than roughly 86% of the state. Across the county's 26 cities, average rent runs $1,976 per month against a rent-burden rate of 36.3% and a renter share of 42.4%, a combination that puts sustained collection pressure on landlords even during stable economic stretches.

Knowing where a specific property falls inside that range matters more than the county average alone.

The cities inside Boulder County

Boulder eviction risk carries the county's highest eviction-risk score at 5.8/10, the only city in the county to reach that level.

Glendale scores 4.4/10, and several smaller communities including Seven Hills, Gold Hill, and Allenspark also sit at 5.7 to 5.8.

On the lower end, Niwot scores 4.4/10, the lowest mark in the county, and Gunbarrel comes in at 4.7/10. The city of Boulder itself, the county seat with 106,433 residents, scores 4.9/10, which is below the county average despite Boulder's well-documented cost and regulatory environment.

Risk here is genuinely hyper-local, and a few miles of distance between properties can move a landlord into a materially different risk tier.

State-level laws that apply here

Colorado eviction laws's landlord-tenant framework is set primarily under C.R.S. § 38-12 (Tenants and Landlords). For nonpayment of rent or a material lease violation, Colorado eviction laws requires a 10-day notice to the tenant before a landlord can proceed. A substantial violation shortens that window to 3 days. No-fault terminations for owner move-in or renovation require a 90-day notice under HB24-1098. State law also requires just cause for most terminations, a provision that limits a landlord's flexibility at lease-end. Understanding the full Colorado eviction laws eviction process before acquiring rental property here is essential, because missteps at the notice stage restart the clock and extend a case that could already run 21 to 45 days for an uncontested matter, or 60 to 120 days if contested.

Colorado eviction costs add up quickly: court filing fees run $105 to $200, sheriff lockout fees run $50 to $200, and attorney fees typically range from $750 to $3,500.

Colorado eviction laws does not preempt local rent control, so individual municipalities retain the authority to impose their own rules, and landlords should verify local ordinances before acquiring property in any of the county's 26 cities.
