Emotional Support Animal (ESA) Letters in Centennial, CO

One household in five

Centennial has 42,233 occupied homes, and renters live in 8,203 of them. That is a renter share of 19.4%: the lowest of any of Colorado’s twenty largest cities, barely one household in five, set against 33.8% statewide and 52.8% in Boulder at the other end of the range. Both housing figures are 2020-2024 American Community Survey five-year estimates, table B25003; the population, 108,853, is the Census Bureau’s Vintage 2024 subcounty estimate.

A share that low changes the texture of a tenancy rather than the law of it. Where four homes in five are lived in by their owners, the fifth is often a single house let by somebody with one property rather than a portfolio: no leasing office, no resident portal, no written accommodation procedure. It also leaves a renter short of what tenants lean on most: a neighbour in the same position who has asked about an animal and can say how it went.

The city does not run a housing department

Centennial has none. What it offers instead is its Community Resource Hub, described on the page as a guide to local community and civic organisations, sorting residents toward outside partners across categories including housing, health services and job assistance. It is a useful directory that points outward by design.

So nothing inside Centennial resolves an assistance animal dispute: the duty is state law, and the complaint ends with a state agency. Learn that early, rather than lose part of a one-year deadline hunting for a city office that was never built.

What a small landlord may believe

Owners of one or two rental houses often assume fair housing rules were written for apartment companies, and federal law gives that a foothold: it does not reach owner-occupied buildings of four units or fewer.

Colorado declined to copy the gap. Nothing in its disability rules turns on how many units a landlord owns or whether the landlord lives on site. The state act holds one small-property carve-out, at C.R.S. § 24-34-502(1.5)(a) for landlords with three or fewer units, and it is confined to the source-of-income rules about vouchers and where the rent money comes from.

What governs instead is C.R.S. § 24-34-502.2(2)(b). Where a person with a disability needs a rule, policy, practice or service adjusted for equal opportunity to use and enjoy a dwelling, refusing that reasonable accommodation is discrimination, and C.R.S. § 24-34-502(1)(k) makes it an unfair housing practice. Building size is not part of the test. The individual who owns one Centennial house owes exactly what a large complex owes.

What August 12 gives a one-house tenant

The governor signed House Bill 26-1045 on May 19, 2026 as chapter 202 of the session laws; it takes effect on August 12, 2026. Its legislative declaration puts the purpose plainly: rescinded federal guidance, restored by writing it into state law.

C.R.S. § 24-34-301(2.5) draws a broad category: an animal providing therapeutic emotional support to a person with a disability counts, as does one that works, performs tasks, or assists them. Service animals and emotional support animals sit inside it, the second defined at C.R.S. § 24-34-301(8.5). Two presumptions follow: allowing an assistance animal in housing is presumed to be a reasonable accommodation under C.R.S. § 24-34-502.2(2)(b)(II)(A), and prohibiting them altogether is presumed discriminatory under C.R.S. § 24-34-502.2(2)(b)(II)(B).

Ask first, and put it in writing

The first presumption carries a condition: it runs in your favour where the housing provider has been given an opportunity to engage in an interactive accommodation process. In Centennial nothing creates that record for you, no portal timestamps the request.

So write it down. A dated email asking for an exception to the pet clause and offering documentation meets the condition and leaves the proof in your sent folder. Send it before the animal arrives; moving in first and quoting the statute afterwards hands the owner an argument.

What may be asked, and who may sign

Being asked for paperwork is not a refusal. Under C.R.S. § 24-34-502.2(2)(b)(II)(C), a housing provider may seek reasonable documentation (of the disability, or of the disability-related need), and may conduct a good faith interactive process, without either being discrimination. Where the disability or the need is obvious, that ends. Those two subjects are the boundary: breed, weight, training history and any online listing fall outside, and no Colorado body registers or certifies assistance animals. A demand for registration asks for something that does not exist. Underneath sits C.R.S. § 24-34-501(1.3): disability includes a mental impairment, any behavioural, mental or psychological disorder.

Colorado regulates the signer, and the rule divides by profession. C.R.S. § 12-245-229(3)(a) stops a mental health licensee (a psychologist, licensed counsellor, social worker, or marriage and family therapist), from making the finding without having met the patient in person. C.R.S. § 12-240-144(3)(a) lets a physician meet the patient in person or by telemedicine. Both then owe the same three things: sufficient familiarity with the patient, legal and professional qualification, and two findings rather than one, disability first, then a separate finding on the disability-related need.

C.R.S. § 18-13-107.3 makes intentionally misrepresenting an entitlement to an assistance animal a class 2 civil infraction, but only where a written or verbal warning came first: an element, not a courtesy. A written finding under C.R.S. § 12-240-144(1)(a) or § 12-245-229(1)(a) is an affirmative defence, and its absence is expressly not proof of the offence.

Charges, breed lists and the insurance answer

For a pet, C.R.S. § 38-12-106 fixes the ceiling: additional deposit no higher than $300 and refundable, additional rent no higher than $35 a month or 1.5% of monthly rent, whichever is greater. An assistance animal is not a pet, and dropping those charges is the exception or adjustment to a rule, policy, practice or service that C.R.S. § 24-34-501(3.5) calls a reasonable accommodation, a definition reaching public and common-use spaces.

When the rental is a house, the refusal often arrives dressed as insurance. C.R.S. § 10-4-110.8(16) closed that door on January 1, 2024. A homeowner’s or dwelling fire policy may not be refused or surcharged over a dog’s breed, and the carrier may not ask the breed, only whether the dog has been declared dangerous. An owner saying the carrier forbids your animal describes something unlawful.

On damage, C.R.S. § 24-34-502(1)(a)(III) says from August 12 that presence proves nothing. An animal living in the home is no direct threat to health or safety, and no basis for presuming substantial physical damage to others’ property. Documented, specific conduct by the animal may be weighed; fear of it may not.

Handing back the keys

C.R.S. § 38-12-103, rewritten with effect from January 1, 2026, decides the deposit: back within thirty days, or sixty where the lease says so, and reduced only for unpaid rent, unpaid utilities, other lawful charges in the lease, and repair of damage beyond normal wear and tear that did not predate the tenancy.

The proving falls on the landlord (both that a withholding was not wrongful and how large the actual damages ran), and holding back 125% or more of that figure is presumed unreasonably excessive. Under subsection (11)(c), carpet cannot be called substantially and irreparably damaged if it was not replaced with new carpet in the preceding ten years. Subsection (1.5) lets either party request a walk-through, subsection (8) gives the landlord fourteen days to produce the photographs, invoices or estimates behind a charge, and wrongful retention costs treble damages plus attorney fees and costs after seven days’ written notice of intent to sue. An owner with one property may know none of this. It binds them anyway.

Where a Centennial complaint goes

To the Colorado Civil Rights Division, on 303-894-2997, or 720-432-4294 in Spanish. Under C.R.S. § 24-34-504(1) the clock runs one year from the unfair housing practice, and the Division says it cannot be extended. Mind the step that catches people out: sending intake through CaseConnect is not filing a charge, since the charge is drafted and signed after intake. Once filed, most housing matters are dual-filed with HUD, the Division being a HUD-certified Fair Housing Assistance Program agency.

Free help is organised by county. The Denver Metro Fair Housing Center says it is active in seven counties, Arapahoe among them. Colorado Legal Services covers Arapahoe County from its Denver Metro office and staffs the Arapahoe County eviction clinic on Tuesdays and Thursdays, 9:30 a.m. to 1:30 p.m., at 1790 West Littleton Blvd in Littleton. One town over, and open only to people at the courthouse named on their summons, on their court date. South Metro Housing Options runs Housing Choice Vouchers.

Colorado enacted the country’s first statewide fair housing law in 1959, nine years ahead of the federal Act. In the city that rents out less of itself than anywhere else in Colorado, that law is the one part that does not depend on which landlord you found.
