## Five thousand nine hundred and ninety-two rented homes

Castle Rock contains 28,219 occupied homes, and renters live in 5,992 of them.
That is a renter share of 21.2% against 33.8% for Colorado as a whole, on the
2020-2024 American Community Survey five-year estimate, table B25003. Of the
state's twenty largest cities, only Centennial rents less, at 19.4%. The
town's population is 83,213 on the Census Bureau's Vintage 2024 subcounty
estimate.

Four front doors in five open onto their owner. A renter here asking about an
assistance animal is asking something most neighbours never will, and the
town's civic plumbing matches.

## The finding: Castle Rock has no local door

There is no municipal civil-rights body here, no human-relations commission,
and no town fair housing office. The town's own website carries no housing or
human-rights section. If a landlord here turns down your animal, no counter at
Castle Rock town hall handles it.

That costs you less than it sounds. Fair housing in Colorado is enforced by
the state, not by towns, so nothing local was ever going to decide your case.
What changes is your route: you start at state level instead of arriving
there after a local attempt fails.

## The size of your landlord changes nothing

In a town this owner-occupied, your landlord may well be a person rather than
a company. Colorado does not scale the duty down to match.

C.R.S. § 24-34-502.2(2)(b) treats the refusal itself as discrimination. If a
person with a disability needs an exception to a rule, policy, practice or
service to use and enjoy their home on equal terms, saying no is the
violation. C.R.S. § 24-34-502(1)(k) makes breaching that section an unfair
housing practice.

Federal law stops short of owner-occupied buildings with four units or fewer;
Colorado law does not, and the Colorado Civil Rights Division says so
directly. The lone small-landlord exemption in the state act,
C.R.S. § 24-34-502(1.5)(a) for landlords with three or fewer units, is
confined to the source-of-income rules and never reaches disability.
Disability is drawn broadly too: C.R.S. § 24-34-501(1.3) takes in a mental
impairment, meaning any behavioural, mental or psychological disorder.

## What August 12, 2026 adds

House Bill 26-1045 was signed on May 19, 2026 as chapter 202 of the session
laws and takes effect on August 12, 2026. Its legislative declaration says the
point is to restore rescinded federal guidance by writing it into state law.

Vocabulary comes first. 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, covering both an emotional support
animal and a service animal. C.R.S. § 24-34-301(8.5) defines the emotional
support animal on its own: one providing solely emotional support to ease a
symptom or effect of a disability.

Then the presumptions. Allowing an assistance animal in housing is presumed
reasonable under C.R.S. § 24-34-502.2(2)(b)(II)(A); banning them outright is
presumed discriminatory under C.R.S. § 24-34-502.2(2)(b)(II)(B). And
C.R.S. § 24-34-502(1)(a)(III) provides that an animal's mere presence is
neither a direct threat to health or safety nor presumed to cause substantial
physical damage to other people's property. A landlord may still raise
documented, specific conduct. What the dog looks like is not conduct.

## Nobody here builds the paper trail for you

Presumption (A) has a string attached. It applies where the housing provider
has been given an opportunity to engage in an interactive accommodation
process. A real chance to discuss the request before anything is decided.

A large managed building has a portal that makes that record for you. Renting
from an owner, you make it yourself. One dated email does the job: say you
have a disability, ask for an exception to the animal rule as a reasonable
accommodation, and offer the documentation. Send it before the animal moves
in, arriving first and citing the statute afterwards gives away the
presumption for nothing.

## Reasonable documentation, and who may sign it

Being asked for paperwork is not, by itself, discrimination.
C.R.S. § 24-34-502.2(2)(b)(II)(C) protects two moves: a request for reasonable
documentation of the disability or the disability-related need, and a good
faith interactive process. That protection ends where the disability or the
need is obvious.

Those two subjects are the boundary. Nothing entitles a landlord to your
medical history, to breed papers, or to an entry on a register. None exists,
and the sites selling one sell a certificate with no legal effect.

Colorado does regulate the signer, and the rule splits by profession.
C.R.S. § 12-245-229(3)(a) stops a mental health licensee (psychologist,
counsellor, social worker, or marriage and family therapist), from making the
finding unless they have met you **in person**. C.R.S. § 12-240-144(3)(a)
allows a physician to meet you in person or by telemedicine. Either must be
sufficiently familiar with you and professionally qualified, and must produce
a written finding on disability plus a separate written finding on the
disability-related need.

That document is also protective. Under C.R.S. § 18-13-107.3, intentionally
misrepresenting an entitlement to an assistance animal is a class 2 civil
infraction, but a written or verbal warning must have come first, and a
written finding under C.R.S. § 12-240-144(1)(a) or § 12-245-229(1)(a) is an
affirmative defence whose absence is expressly not proof of the offence.

## Charges, and the insurance line

C.R.S. § 38-12-106 has capped pet charges since January 1, 2024. An additional
pet deposit may not exceed three hundred dollars and has to be refundable.
Additional pet rent may not exceed thirty-five dollars a month or one and
one-half percent of the monthly rent, whichever is greater, so a higher rent
lifts that ceiling.

Those are the limits for a pet. An approved assistance animal is not a pet,
and dropping the charge is the sort of exception C.R.S. § 24-34-501(3.5) has
in mind when it defines a reasonable accommodation as an exception or
adjustment to a rule, policy, practice or service.

If the refusal arrives dressed as insurance, test it against
C.R.S. § 10-4-110.8(16). An insurer may not refuse or surcharge a homeowner's
or dwelling fire policy over a dog's breed, and may not ask about breed beyond
whether the dog has been declared dangerous. An owner letting out a Castle
Rock house insures it under one of those very policies, so the carrier being
blamed is barred from doing what they say it did.

## The deposit, after you hand back the keys

C.R.S. § 38-12-103 was rewritten with effect from January 1, 2026. The deposit
comes back inside thirty days, or up to sixty where the lease says so. Four
things may come out of it: unpaid rent, unpaid utilities, other lawful charges
the lease itself names, and repair of damage past normal wear and tear that was
not there before you moved in.

The weight now falls on the landlord. They must show the withholding was
justified and put a figure on the damage, and a deduction reaching 125% of
that figure is presumed to exceed it unreasonably. Carpet has its own bar: it
cannot count as substantially and irreparably damaged unless new carpet went
down in the preceding ten years, under subsection (11)(c).

Either party may ask for a walk-through under subsection (1.5), and a written
request obliges the landlord to produce the photographs, invoices or estimates
behind a charge within fourteen days under subsection (8). Wrongful retention
costs treble damages plus attorney fees and costs after seven days' written
notice of intent to sue.

## The three doors that are open to you

The charge goes to the Colorado Civil Rights Division, on 303-894-2997 or
720-432-4294 in Spanish. C.R.S. § 24-34-504(1) allows one year from the unfair
housing practice, and the Division states it cannot extend that even for good
cause. Watch the procedural step: CaseConnect intake files nothing by itself,
since the charge is drafted and signed after it. Holding HUD certification as
a Fair Housing Assistance Program agency, the Division dual-files most housing
matters under a state and a federal number.

For fair housing questions, the Denver Metro Fair Housing Center works across
seven counties, Douglas among them. For legal help, Colorado Legal Services
covers Douglas County from its Denver Metro office at 1560 Broadway, Suite
1100, on 303-837-1313; no office sits in Castle Rock. Its in-person eviction
clinics sit in courthouses in seven other counties, open only at the
courthouse named on your summons and only on your court date. There is also
the Douglas County Housing Partnership, and for a renter question that is not
yet a case, Colorado Housing Connects answers a bilingual statewide helpline
on 844-926-6632, staffed by Brothers Redevelopment since 2014.

Castle Rock never built a fair housing body of its own. The law that reaches a
renter here is older than the federal Act, Colorado passed the country's
first statewide version in 1959. In a town where the renter is the exception,
that protection was written a long way up the road, and it still arrives.

## What Castle Rock 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)

## Frequently asked questions

### I rent a house in Castle Rock from the owner, not a company. Does the assistance animal law still apply?

Yes. Colorado does not excuse a landlord from the disability rules because the landlord is small. Federal fair housing law leaves owner-occupied buildings of four units or fewer alone; Colorado law does not, and the Colorado Civil Rights Division says state law reaches more properties than the federal statute does. The one small-landlord carve-out in the state act, C.R.S. § 24-34-502(1.5)(a) for landlords with three or fewer units, is confined to the source-of-income rules and does not touch disability. C.R.S. § 24-34-502.2(2)(b) makes refusing a necessary reasonable accommodation discrimination whoever the landlord is.

### My Castle Rock lease says no animals of any kind. Can the landlord enforce that against my ESA?

A blanket clause is a rule, and C.R.S. § 24-34-501(3.5) defines a reasonable accommodation as an exception or adjustment to a rule, policy, practice or service. From August 12, 2026, C.R.S. § 24-34-502.2(2)(b)(II)(B) goes further and presumes that a complete prohibition of assistance animals in housing is discriminatory. The landlord can still point to documented, specific conduct by your animal that poses a direct threat or causes substantial damage, but under C.R.S. § 24-34-502(1)(a)(III) the animal simply being there is neither.

### Can a Castle Rock landlord charge me pet rent or a pet deposit for an emotional support animal?

Not once the animal is approved as an assistance animal, because waiving that charge is the exception to a policy that C.R.S. § 24-34-501(3.5) contemplates. The caps in C.R.S. § 38-12-106, in force since January 1, 2024, apply to actual pets: an additional deposit of no more than three hundred dollars, which must be refundable, and additional rent of no more than thirty-five dollars a month or one and one-half percent of the monthly rent, whichever is greater. Note the word greater, a higher rent lifts that ceiling.

### My landlord says their insurer will not cover my dog's breed. Is that a lawful reason to refuse?

It describes something the insurer is not permitted to do. C.R.S. § 10-4-110.8(16), effective January 1, 2024, bars an insurer from refusing, cancelling or surcharging a homeowner's or dwelling fire policy because of a dog's breed or mix of breeds, and bars the insurer from asking about breed at all except whether the dog has been declared dangerous. Since a Castle Rock house or townhome let by its owner is usually insured under exactly one of those policy types, the objection generally does not survive being checked.

### Who is allowed to write my documentation, and is there a Colorado ESA registry?

There is no registry, in Colorado or anywhere else, and no website that sells one creates any legal status. What Colorado regulates is the professional. Under C.R.S. § 12-245-229(3)(a), a mental health licensee (psychologist, counsellor, social worker, or marriage and family therapist) may not make the finding unless they have met you in person. A physician has the wider option under C.R.S. § 12-240-144(3)(a): in person or by telemedicine. Whoever signs must be sufficiently familiar with you and legally and professionally qualified, and the finding comes in two parts. One on the disability, a second and separate one on the disability-related need.

### Castle Rock has no fair housing office. Where does my complaint actually go?

To the Colorado Civil Rights Division, on 303-894-2997 or 720-432-4294 in Spanish. There is no municipal civil-rights, human-relations or fair-housing body in Castle Rock, so the state agency is the first stop rather than a fallback. C.R.S. § 24-34-504(1) gives you one year from the unfair housing practice before the claim is barred, and the Division says it cannot extend that even for good cause. Submitting intake through CaseConnect is not the same as filing a charge (the charge is drafted and signed afterwards), so leave time for that step.

### Is there free help for a renter in Douglas County?

Yes, though none of it is based in Castle Rock. Colorado Legal Services covers Douglas County from its Denver Metro office at 1560 Broadway, Suite 1100, on 303-837-1313. The Denver Metro Fair Housing Center states that it works across seven counties including Douglas, and takes fair housing questions. Colorado Housing Connects runs a bilingual statewide renter helpline on 844-926-6632, operated by Brothers Redevelopment since 2014. At county level there is also the Douglas County Housing Partnership.
