Colorado Landlord Laws in 2026: What Every Loveland Owner Needs to Know

Colorado has been one of the most active states in the country when it comes to landlord-tenant legislation. If you own a rental property in Loveland, Fort Collins, Greeley, or anywhere along the Front Range, the rules you operated under three years ago are not the rules you operate under today. Below is a no-nonsense rundown of the laws that matter most heading into 2026.

This is general information, not legal advice. When in doubt, talk to a Colorado attorney or your property manager.

Warranty of Habitability (HB 19-1170, expanded since)

Every residential lease in Colorado includes an implied warranty that the unit is fit for human habitation. That covers heat, hot and cold running water, working plumbing and electrical, weatherproof roof and exterior walls, and freedom from mold, vermin, and gas leaks. The 2019 update sharply tightened the response timelines: 24 hours for life-threatening conditions, 96 hours for everything else once written notice is received.

Owners who ignore a habitability complaint can face rent abatement, lease termination by the tenant, and attorney's fees. The cure is simple: respond in writing within 24 hours, dispatch a vendor immediately, and document everything.

Security Deposits (CRS 38-12-103, updated 2024)

Colorado caps how long you have to return a security deposit and itemize deductions:

• One month by default after lease termination
• Up to 60 days only if the lease specifically allows it
• Deductions must be itemized in writing with receipts available on request

Miss the deadline by even one day and you forfeit your right to withhold any portion — plus the tenant can recover triple the wrongfully withheld amount, court costs, and attorney's fees. This is the single most common mistake we see new landlords make.

Late Fee Limits (HB 21-1121)

Late fees in Colorado are now capped at the greater of $50 or 5% of past-due rent, can only be charged after a 7-day grace period, and must be disclosed in the lease. Stacking fees, daily fees, or "convenience" charges that push the total above the cap are not enforceable.

Application Fees & Screening (HB 19-1106)

You can only charge an applicant for the actual cost of the screening report, and you must provide a copy of the report (or written notice of the result) within 20 days. You must also publish your written rental criteria — credit, income multiplier, criminal look-back, etc. — and apply them consistently to every applicant.

Source-of-Income Discrimination (HB 20-1332)

Refusing to rent to a Section 8, VASH, or other housing-voucher holder solely because of their voucher is illegal in Colorado. You can still apply your standard income, credit, and rental history criteria — you just can't reject the source of the income itself.

Notice to Quit & Eviction (HB 21-1121, HB 22-1377)

For nonpayment of rent on a residential lease, the notice period is now 10 days, up from 3. Lease violations also generally require 10 days. The forms have changed too — Colorado's JDF 101 (Demand for Compliance or Possession) was updated in 2023, and using an outdated form is a fast way to get an eviction case dismissed.

Bed Bugs (HB 19-1328)

Tenants must report a suspected infestation in writing. Landlords must hire a qualified inspector within 96 hours and remediate within timelines tied to the inspector's findings. Tenants are not financially responsible unless they can be proven to have caused the infestation — which is almost never.

Notices for Rent Increases (HB 21-1121)

On month-to-month tenancies, a rent increase requires 60 days' written notice. Mid-lease rent increases are not allowed unless the lease specifically authorizes them (and they almost never should).

Colorado law is going to keep evolving. The key isn't memorizing every statute — it's building a system (and surrounding yourself with people) that updates with the law. If you'd like us to audit your current lease and process at no cost, reach out anytime.
