Colorado Landlord-Tenant Law Basics: A Denver Owner's Starter Guide

Published 2026-02-10 · Handled PM

Colorado has tightened its landlord-tenant rules substantially in recent years. Here are the fundamentals every Denver-metro owner should understand before renting out a home.

Owning a rental in Colorado has gotten more rewarding — and more regulated. A wave of legislation over the past several years reshaped how security deposits, habitability, late fees, evictions, and disclosures work, and the rules tend to favor tenants more than they once did. None of it should scare a prepared owner off, but all of it is worth understanding before you hand over the keys.

Security deposits

Colorado caps how long you can hold a departing tenant's deposit. In general, you must return the deposit within one month of the lease ending, and a lease may extend that window only up to 60 days. If you keep any portion, you have to provide a written, itemized statement of deductions. The teeth here are real: a landlord who wrongfully withholds a deposit can be liable for treble (triple) damages plus the tenant's attorney fees. The practical takeaway is to document condition thoroughly at move-in and move-out — dated photos, a signed condition report — so any deduction is defensible.

The warranty of habitability

Colorado's warranty of habitability requires rental housing to be fit for human habitation and to meet basic standards: working heat, plumbing, hot and cold running water, functioning electrical, weatherproofing, and freedom from serious pest infestations, among others. Recent updates shortened the timelines for responding to serious problems and expanded tenant remedies when a landlord fails to act. If a tenant reports a habitability issue in writing, the clock starts — so a fast, documented maintenance response isn't just good service, it's compliance.

Late fees and the grace period

Colorado now restricts residential late fees. There's a required grace period before any late fee can be charged, a cap on the amount, and limits on charging repeated or compounding late fees for the same missed payment. You also generally can't treat a late fee as rent for the purpose of eviction. Because the exact numbers have been adjusted by legislation, set your lease's late-fee language to the current statute rather than an old template.

Notice periods, rent increases, and eviction

Notice requirements have lengthened. Colorado expanded the notice a landlord must give for certain rent increases and for terminating some tenancies, and enacted "for-cause" protections that limit no-fault, non-renewal evictions in many situations. Eviction (formally, "forcible entry and detainer") is a court process with strict notice and filing steps; skipping or botching a step can dismiss your case and cost you weeks. This is one area where professional management — or at least a Colorado attorney — earns its keep.

Required disclosures

Colorado owners must provide several disclosures, and the list has grown. Among them: a radon disclosure and brochure for residential transactions (Colorado is a high-radon state), bed-bug-related disclosures and duties, and information about the habitability process. Missing a required disclosure can create liability independent of anything else going on with the tenancy.

Application and screening rules

When you screen applicants, Colorado limits what you can charge for an application, requires you to provide the reason for a denial, and restricts how far back and how you may consider certain rental and credit history. Federal fair-housing law applies on top of that — you must apply consistent, non-discriminatory criteria to every applicant. Written, uniform screening standards are your best protection against a fair-housing complaint.

The bottom line for Denver-metro owners

Colorado's rules reward owners who are organized and documented and punish those who improvise. Get your lease onto current statutory language, respond to habitability requests quickly and in writing, handle deposits carefully, and keep your disclosures complete. If that sounds like more than you want to manage yourself, that's precisely the work a full-service manager like Handled PM absorbs — keeping your leases, notices, and disclosures compliant so a paperwork slip never turns into a treble-damages problem.
