Published June 2026 ~6 min read PawTenant Editorial — reviewed for accuracy

Quick summary

Rising rents: Denver, Boulder, Colorado Springs, and Fort Collins have seen strong rent growth.
State protections: Colorado law protects assistance animals in housing and penalizes misrepresentation.
Provider knowledge: documentation should come from a provider with knowledge of your need.
Approved ESAs: an approved emotional support animal is generally not charged pet rent or deposits — decided individually, never guaranteed.

A renter at home in Colorado with their emotional support animal

Colorado's Front Range rental market has grown quickly, and pet rent is a common add-on. This guide explains how pet rent works in Colorado, the state's assistance-animal housing protections, and when an approved emotional support animal may not be charged those fees.

Pet rent in Colorado's rental market

In Denver, Boulder, Colorado Springs, and Fort Collins, many properties charge monthly pet rent on top of base rent, often alongside a one-time pet fee or deposit and sometimes per pet. Over a multi-year lease, the recurring monthly portion is usually the largest pet-related cost.

With Colorado rents climbing in recent years, the cumulative impact of pet rent can be meaningful — worth estimating before you sign.

Colorado's assistance-animal housing protections

Colorado adds protections on top of the federal Fair Housing Act. State law addresses assistance animals in housing and penalizes intentionally misrepresenting an animal as a service animal. Documentation supporting an ESA should come from a provider who has knowledge of your disability-related need and is licensed in Colorado.

When a reasonable-accommodation request is approved, an approved emotional support animal is generally not charged pet rent, a pet deposit, or pet fees. Each request is reviewed individually, however, and a letter does not guarantee approval or a fee waiver.

What an apartment generally cannot do for an approved ESA

Charge pet rent, a pet deposit, or pet fees for an approved assistance animal.
Refuse based only on a no-pet policy, breed, size, or weight.
Require you to "register" the animal or buy a certificate, ID card, or vest.
Demand your specific diagnosis or full medical records.

These are general Fair Housing principles, not legal advice, and Colorado and local rules can add protections. Each accommodation request is reviewed individually, and a housing-focused ESA letter supports but does not guarantee approval or any fee waiver.

Colorado pet rent & ESA letters: FAQ

Generally not. Under the federal Fair Housing Act and Colorado law, an approved emotional support animal is usually not treated as a pet, so pet rent, pet deposits, and pet fees typically do not apply once a reasonable-accommodation request is approved. The decision is made individually, and a letter does not guarantee approval or a fee waiver.
