Free tenant help for south metro has a Littleton address

Arapahoe County’s eviction clinic is here. Colorado Legal Services runs it on Tuesday and Thursday, 9:30 a.m. to 1:30 p.m., at 1790 West Littleton Blvd, and it belongs to the whole county, not just the city it sits in. A renter from Centennial, or from the Arapahoe side of Aurora, travels to Littleton for it.

One limit matters more than the address: help is offered only on the day of the court date printed on your summons, so arriving early to prepare gets you nothing. Case work away from the clinic runs from the Colorado Legal Services office at 1560 Broadway, Suite 1100, Denver, on 303-837-1313, covering Arapahoe with Adams, Broomfield, Denver, Douglas, Elbert, Gilpin and Jefferson.

Two clocks, and they run at completely different speeds

A tenant told to get rid of an assistance animal can end up inside two processes at once, and confusing them is expensive.

The eviction clock is short, physical, and set by somebody else. A summons names a courthouse and a date, and the West Littleton Blvd clinic is open to you on that date and no other. If matters reach a writ of restitution, C.R.S. § 13-40-122(2.5) governs what happens to a pet when the writ is executed, and C.R.S. § 38-20-102(3)(a) keeps pet animals out of a landlord’s lien for unpaid rent.

The discrimination clock is long, quiet, and administrative. C.R.S. § 24-34-504(1) allows one year from the unfair housing practice to file a housing charge with the Colorado Civil Rights Division, after which the claim is barred. The Division says it cannot extend that year for any reason.

Neither clock stops the other. Courtroom events add no days to the twelve months, and opening a file with the Division moves no court date. One trap sits inside the year: sending information through the Division’s CaseConnect system is not filing a charge, because the charge is drafted and signed afterwards.

The smallest of the twenty rents more than its neighbour

Littleton has 20,449 occupied homes and 7,941 of them are rented: a 38.8% renter share on the 2020-2024 American Community Survey five-year estimate, against 33.8% for Colorado as a whole.

By population it is the smallest of Colorado’s twenty largest cities, at 44,879 on the Census Bureau’s Vintage 2024 estimate, yet it rents out a larger slice of its housing than the suburbs around it. Centennial sits at 19.4%, two adjoining places nearly twenty points apart, so what worked for a friend one town over is a poor guide here.

What lands on August 12, 2026

House Bill 26-1045 takes effect that day, and its legislative declaration says the purpose is to restore rescinded federal guidance by putting it into state law. C.R.S. § 24-34-301(2.5) defines an assistance animal as one that works, performs tasks, assists, or gives therapeutic emotional support to a person with a disability, and says outright that the term covers an emotional support animal as well as a service animal.

C.R.S. § 24-34-502.2(2)(b)(II)(A) then presumes that letting an assistance animal live in housing is a reasonable accommodation, while C.R.S. § 24-34-502.2(2)(b)(II)(B) presumes that a complete ban is discriminatory. And C.R.S. § 24-34-502(1)(a)(III) closes off the argument that an animal is a hazard merely by existing: its presence alone is not a direct threat to health or safety and is not presumed to cause substantial physical damage to other people’s property, though documented, specific conduct counts.

The presumption expects you to speak first

Read provision (A) to its end. It operates where the housing provider has been given an opportunity to engage in an interactive accommodation process. That clause is the price of the presumption.

So ask in writing, before the animal moves in, and keep the dated copy. If the answer is a refusal, that exchange fixes the day it happened (the day your one year starts counting from), instead of leaving it to memory.

Size is no defence either. Colorado’s disability protections reach the owner-occupied buildings of four units or fewer that federal law leaves alone, and the carve-out at C.R.S. § 24-34-502(1.5)(a) covers only the source-of-income rules.

Being asked for documents, and whose signature counts

C.R.S. § 24-34-502.2(2)(b)(II)(C) says a housing provider does not discriminate merely by requesting reasonable documentation of the disability or of the disability-related need, or by running a good faith interactive process, unless the disability or the need is obvious.

The request has edges. Two questions are in scope: whether you have a disability: C.R.S. § 24-34-501(1.3) counts a mental impairment, any behavioural, mental or psychological disorder, and whether the animal relates to it. Breed, weight, obedience records and any online listing sit outside the question, and no Colorado body issues a registration or certificate that would answer it anyway.

Who signs depends on the profession. C.R.S. § 12-245-229(3)(a) requires a mental health licensee (psychologist, counsellor, social worker, marriage and family therapist), to have met the patient in person, to be sufficiently familiar with the patient and the disability, and to be legally and professionally qualified. A physician gets the wider rule at C.R.S. § 12-240-144(3)(a): in person or by telemedicine. Both must produce a written finding on disability and a separate one on the need.

That paper does a second job. C.R.S. § 18-13-107.3 makes it a class 2 civil infraction to intentionally misrepresent an entitlement to an assistance animal to get a housing accommodation, but only where a written or verbal warning came first. A written finding under § 12-240-144(1)(a) or § 12-245-229(1)(a) is an affirmative defence, and the absence of one is expressly not proof of the offence.

Pet money, and the line about the insurer

Since January 1, 2024, C.R.S. § 38-12-106 has put a ceiling on pet charges. An additional deposit stops at three hundred dollars and has to be refundable. Additional rent stops at thirty-five dollars a month or one and one-half percent of monthly rent, whichever is greater, greater, not lesser.

Those figures describe pets. An approved assistance animal is not one, and dropping the charge is an exception to a policy of precisely the kind C.R.S. § 24-34-501(3.5) defines: an exception or adjustment to a rule, policy, practice or service that a person with a disability may need in order to use and enjoy housing equally, including public and common-use spaces: the shared laundry and the courtyard, not only the unit.

When a breed list is defended in the insurer’s name, C.R.S. § 10-4-110.8(16) is the reply: an insurer may not refuse a homeowner’s or dwelling fire policy or raise its premium over a dog’s breed, and may not ask about breed beyond whether the dog has been declared dangerous.

The deposit, once the keys go back

C.R.S. § 38-12-103, rewritten with effect from January 1, 2026, gives the landlord thirty days to return the deposit, or sixty where the lease says so, and limits retention to unpaid rent, unpaid utilities, other lawful charges named in the lease, and repair of damage beyond normal wear and tear that did not predate your tenancy.

The burden sits on the landlord, on both the wrongfulness of the withholding and the size of the actual damages. Keeping one hundred twenty-five percent or more of those damages is presumed to exceed them unreasonably. Carpet may not be called substantially and irreparably damaged if it was not replaced with new carpet in the previous ten years; paint has a matching rule.

A walk-through inspection is available on either party’s request under C.R.S. § 38-12-103(1.5), and fourteen days after a written request the landlord must hand over photographs, receipts or estimates, under C.R.S. § 38-12-103(8). Wrongful retention costs treble damages plus attorney fees, after seven days’ notice.

Where a Littleton complaint goes, and who helps free

Littleton runs no civil-rights or fair-housing office of its own, so the charge goes to the Colorado Civil Rights Division on 303-894-2997, with a Spanish line on 720-432-4294. Once it is filed the provider has ten days to answer and you have ten to reply, and where the Division finds probable cause and conciliation fails, housing cases are set for hearing automatically. As a HUD-certified Fair Housing Assistance Program agency it dual-files most housing matters, so a Littleton case usually carries a state number and a federal one.

The Denver Metro Fair Housing Center states it works across seven counties, Arapahoe among them, so Littleton sits inside its area. South Metro Housing Options is the city’s housing authority and runs Housing Choice Vouchers here. Colorado Housing Connects, the bilingual statewide renter helpline run by Brothers Redevelopment since 2014, answers on 844-926-6632.

Colorado passed the country’s first statewide fair housing law in 1959, nine years ahead of the federal Act. The August 12, 2026 presumptions are the latest layer, and the clinic on West Littleton Blvd is where south metro tenants learn what any of it means on a Tuesday morning.

What Littleton Landlords Can and Cannot Do

Cannot ✕

  • Cannot operate a complete prohibition on assistance animals, which C.R.S. § 24-34-502.2(2)(b)(II)(B) presumes to be discriminatory from August 12, 2026
  • Cannot treat the mere presence of an assistance animal as a direct threat to health or safety, or presume it will cause substantial physical damage to the property of others, under C.R.S. § 24-34-502(1)(a)(III)
  • Cannot refuse to make reasonable accommodations in rules, policies, practices or services where necessary to afford a person with a disability equal opportunity to use and enjoy a dwelling, under C.R.S. § 24-34-502.2(2)(b)
  • Cannot rely on the small-landlord and owner-occupied exemptions that exist under federal law, because Colorado's disability provisions carry no equivalent, the three-or-fewer-units carve-out at C.R.S. § 24-34-502(1.5)(a) applies only to the source-of-income rules
  • Cannot charge a pet deposit or pet rent for an approved assistance animal, because waiving that charge is an exception to a policy within the definition of reasonable accommodation at C.R.S. § 24-34-501(3.5)
  • Cannot take more than a three-hundred-dollar refundable pet deposit, or more than thirty-five dollars a month or one and one-half percent of rent, whichever is greater, for an ordinary pet under C.R.S. § 38-12-106
  • Cannot justify a breed restriction by pointing at its insurer, since C.R.S. § 10-4-110.8(16) bars an insurer from pricing or refusing a policy on dog breed and from asking about breed at all
  • Cannot keep any part of a deposit without a written statement of the exact reasons within thirty days, and cannot charge for carpet replacement across a unit where the carpet was not replaced within the previous ten years, under C.R.S. § 38-12-103
  • Cannot place a lien on the animal itself for unpaid rent, under C.R.S. § 38-20-102(3)(a)

Can ✓

  • May request reasonable documentation supporting the claim of disability or the disability-related need, and may run a good faith interactive process, without that being discrimination, unless the disability or the need is obvious, under C.R.S. § 24-34-502.2(2)(b)(II)(C)
  • May act on documented, specific conduct of the animal that poses a direct threat to health or safety or causes substantial physical damage to property
  • May hold a tenant responsible for damage the animal actually causes, provided it exceeds normal wear and tear, did not preexist the tenancy, and is substantiated with the photographs, invoices or estimates C.R.S. § 38-12-103(8) requires on request
  • May ask for a walk-through inspection at the end of the tenancy, as may the tenant, under C.R.S. § 38-12-103(1.5)

ESA Letter FAQs for Littleton, CO

The Arapahoe County eviction clinic is in Littleton. Can I use it?

It is held on Tuesday and Thursday, 9:30 a.m. to 1:30 p.m., at 1790 West Littleton Blvd, and it serves the whole of Arapahoe County rather than Littleton alone, so renters from Centennial and the Arapahoe side of Aurora come here for it. One rule limits it sharply: help is available only on the day of the court date named on your summons, so there is no turning up early to prepare. Case work outside the clinic runs from the Colorado Legal Services office at 1560 Broadway, Suite 1100, in Denver, on 303-837-1313, which covers Arapahoe along with Adams, Broomfield, Denver, Douglas, Elbert, Gilpin and Jefferson counties.

I am facing eviction over my assistance animal and I also want to complain. Which deadline matters?

Both, and they are nothing alike. The eviction deadline is set for you: the summons names a courthouse and a date, and the Littleton clinic can only help you on that date. The discrimination deadline is your own to manage, C.R.S. § 24-34-504(1) gives one year from the unfair housing practice to file a housing charge with the Colorado Civil Rights Division, and the Division says it cannot extend that year for any reason. Neither clock pauses the other. Sending information through the Division's CaseConnect system is also not the same as filing a charge, since the charge is drafted and signed later, so a year spent in intake protects nothing.

Does Littleton have its own fair housing office?

No. There is no city civil-rights or fair-housing body here, so a housing discrimination charge goes to the Colorado Civil Rights Division on 303-894-2997, with a Spanish-language line on 720-432-4294. The Denver Metro Fair Housing Center states that it works across seven counties including Arapahoe, which puts Littleton inside its area, and it can take fair housing questions. South Metro Housing Options is Littleton's housing authority and administers Housing Choice Vouchers locally.

My Littleton landlord owns the building and lives in it. Is that an exemption?

Not from the disability rules. Federal law leaves owner-occupied buildings of four units or fewer alone, but Colorado's protections reach them. The three-or-fewer-units carve-out in C.R.S. § 24-34-502(1.5)(a) applies only to the source-of-income provisions, not to disability, so a resident owner in Littleton owes the same duty to consider a reasonable accommodation as a large management company. C.R.S. § 24-34-502.2(2)(b) makes refusing one discrimination where the accommodation is necessary for equal opportunity to use and enjoy the dwelling.

Can a Littleton landlord charge me pet rent or a pet deposit for an assistance animal?

Not once the animal is approved. Removing that charge is exactly the sort of exception to a policy that C.R.S. § 24-34-501(3.5) describes. The caps in C.R.S. § 38-12-106 describe an actual pet: the extra deposit tops out at $300 and the landlord has to give it back, while extra rent tops out at $35 a month or 1.5% of the monthly rent, whichever of those two figures is greater. That cap takes the greater figure, so a higher Littleton rent raises the pet-rent ceiling rather than lowering it, another reason not to let an assistance animal be processed as a pet.

Whose signature will a Littleton landlord's file actually accept?

That of a licensed professional who genuinely assessed you, and Colorado sets the bar differently by profession. Under C.R.S. § 12-245-229(3)(a) a mental health licensee (a psychologist, counsellor, social worker or marriage and family therapist), cannot make the finding without having met the patient in person, being sufficiently familiar with the patient and the disability, and being legally and professionally qualified. Physicians work under the wider rule in C.R.S. § 12-240-144(3)(a), which permits an in-person visit or telemedicine. Either must make a written finding on disability and a separate written finding on the disability-related need. That written finding is also the affirmative defence named in C.R.S. § 18-13-107.3, and the statute says the absence of one is not proof of the offence.

My building's breed list rules out my dog. Does that end it?

No. A breed list is a rule, and C.R.S. § 24-34-501(3.5) treats an exception to a rule as the accommodation itself. From August 12, 2026, C.R.S. § 24-34-502(1)(a)(III) provides that the mere presence of an assistance animal is not a direct threat to health or safety and is not presumed to cause substantial physical damage to other people's property; only documented, specific conduct counts. If the answer comes back that the insurer forbids it, C.R.S. § 10-4-110.8(16) bars an insurer from refusing or surcharging a homeowner's or dwelling fire policy over a dog's breed, and from asking about breed at all beyond whether the dog has been declared dangerous.
