## Key facts

- Population: 157,665
- Households renting: 44.4%
- Typical pet deposit (as a pet): No statutory cap
- Typical pet rent (as a pet): Varies by building
- Breed/weight limits common: yes
- Pet fees, deposits, and breed limits with a valid ESA letter: none (FHA reasonable accommodation)

## The largest city, and the priciest of the big three

Charleston is South Carolina's largest municipality. 157,665 people on the
Census Bureau's 2024 estimate. Of its 68,027 occupied homes, 30,211 are
rented: 44.4 percent on the 2020–2024 American Community Survey five-year
estimate, against 28.1 percent statewide.

Median gross rent here is $1,722. North Charleston, next door, is $1,430;
Columbia, the second-largest city, $1,204; South Carolina as a whole $1,180. A
Charleston renter sits $542 a month above the state median.

That number does more work than it looks. The state caps neither a security
deposit nor pet rent, so both scale with the rent, and Charleston's is the
highest of the big three. Getting an animal treated as an accommodation rather
than a pet is worth more here, in cash, than anywhere else on that list.

## The four-family line

A threshold question comes first, and most pages skip it. South Carolina's Fair
Housing Law does not reach every landlord.

Under § 31-21-70(A), two of its sections stop short of any dwelling with
"living quarters occupied or intended to be occupied by no more than four
families living independently of each other, if the owner actually maintains
and occupies one of the living quarters as his residence." Two conditions, both
mandatory: four families or fewer, and the owner in one of them. An absentee
owner of a fourplex is not inside it.

Section 31-21-70(C)(3) is the far side of the same line. Anyone who "is the
owner of any dwelling designed or intended for occupancy by, or occupied by,
five or more families" counts as trading in rentals, and the chapter reaches
them without qualification.

So the statute turns on a count. Five households in the building, or four with
the owner living elsewhere, and you are inside the chapter. Four with the
owner in one, and it steps back. No listing and no lease tells you
which, so count the letterboxes yourself.

## What an exemption does not withdraw

Three things survive § 31-21-70(A), and a renter unaware of them gives up too
early.

The first is federal law. The subsection suspends two sections of the South
Carolina code and nothing else; the Fair Housing Act draws its exemptions on
different lines and keeps running on them.

The second is the landlord's discretion. An exempt owner is not forbidden to
grant an accommodation, only not compelled to. A small Charleston landlord
meeting the request for the first time will often say yes to a written one
explaining what the animal does.

The third is that the count often goes your way. Section 31-21-70(B) exempts a
private individual owning no more than three single-family houses and renting
without a broker; past that, ordinary landlording is covered.

## The two questions, and the sentence that settles them

Where most states leave this exchange to federal guidance, South Carolina
codified it. Section 31-21-70(N)(1) prints the landlord's script for "an
animal that is not a service animal," in quotation marks in the statute:
"Does the person seeking to use and live with the animal have a
disability that is a physical or mental impairment that substantially limits
one or more major life activities?" and "Does the person seeking to use and
live with the animal have a disability-related need for the animal?"

Subsection (N)(2) is the one to quote at a leasing office. It lets the
landlord ask for paperwork backing the answers, then says the paperwork
"shall be deemed sufficient if it establishes that an individual has a
disability and that the animal in question will provide some type of
disability-related assistance or emotional support."

The duty behind the questions is at § 31-21-70(G)(2): refusing a reasonable
accommodation in "rules, policies, practices, or services" is handicap
discrimination. A no-pets clause is a rule. One drafting quirk is worth
knowing: handicap sits in subdivisions (6) and (7) of § 31-21-40, not the
general list at (1) and (2), so a landlord who reads only the first paragraph
will not find it.

## Deposits at Charleston prices

South Carolina sets no maximum deposit. Section 27-40-410 governs how
the money comes back, not how much a landlord may take, and against a $1,722
median rent that absence is real money.

What it does require is exact. Any deduction "must be itemized by the landlord
in a written notice to the tenant together with the amount due, if any, within
thirty days after termination of the tenancy and delivery of possession and
demand by the tenant, whichever is later." Hand over a forwarding address in
writing when you go: the subsection conditions the remedy on it. A
landlord who fails is liable for "three times the amount wrongfully withheld
and reasonable attorney's fees."

Pet money is unregulated on both sides: the word "animal" appears nowhere in
the Residential Landlord and Tenant Act, so there is no pet-rent limit to
invoke. The accommodation route answers it instead. An approved assistance
animal is an adjustment to a rule, not a pet on a fee schedule.

Where a lease carries a breed or weight condition, the answering provision is
federal. Under 24 C.F.R. § 100.202(d), nothing in the subpart "requires
that a dwelling be made available to an individual whose tenancy would
constitute a direct threat to the health or safety of other individuals or
whose tenancy would result in substantial physical damage to the property of
others." That is an assessment of the animal in front of the landlord, not of
a category decided in advance. Leasing offices reach for
§ 31-21-70(E) instead; its opening words confine it to § 31-21-40(1) and (2),
which leave handicap out.

## The fine that is not about your flat

Mention an ESA in South Carolina and someone brings up a $1,000 fine. The
section exists, § 47-3-980, and it does not describe what you are doing.

Subsection (A) makes it "unlawful for a person to intentionally misrepresent
an animal in his possession as a service animal", knowingly, to get at
something the law reserves for disabled people. A housing accommodation
request claims nothing of the kind, and the code keeps the categories apart:
§ 47-3-920(6) calls an emotional support animal "an animal intended to provide
companionship and reassurance," while § 47-3-920(4)(b) rules that comfort and
companionship "do not constitute work or tasks."

Two limits inside the section rarely survive the retelling. Subsection (D):
"[a] violation of subsection (A) does not constitute a criminal offense," and
no custodial arrest may be made. Subsection (C) caps enforcement questions at
those 28 C.F.R. § 36.302 permits.

Section 47-3-990 is the restrictive one, and it is about shops, not
homes: places of public accommodation "may establish rules and regulations
related to access to such facilities by nonservice animals." A Charleston
restaurant may turn your dog away. Your landlord answers to a different title.

## The two deadlines, and who answers here

A refusal starts two timers of unequal length. The agency route is the short
one: § 31-21-120(B) wants the complaint "within one hundred eighty days after
the alleged discriminatory housing practice occurred," and the commission
administering the chapter under § 31-21-90(A) then has 100 days to
investigate. Court is the long one. § 31-21-140(A) allows a year, and an
action "whether or not a complaint has been filed with the commission," so
a lapsed agency window is not a lapsed case. Either way § 31-21-120(G) leaves
the proving to you: make the request by email, not at the leasing desk.

In the city, **Charleston Pro Bono Legal Services** gives free civil
legal assistance to eligible low-income Charleston County residents, from
advice to representation. **Charleston Legal Access** is a nonprofit law firm
on a sliding scale from $60 an hour across Berkeley, Charleston and Dorchester
counties, housing among its practice areas. **South Carolina
211** (dial 2-1-1, call 866-892-9211, or text a ZIP code to 211-211) is free
and answers around the clock.

## What your letter has to establish

Both sides of the four-family line converge on the same document, and the
state has said what it must do: establish a disability, and establish
"some type of disability-related assistance or emotional support" the animal
supplies. Meet those two and § 31-21-70(N)(2) deems the documentation
sufficient.

Only a licensed professional who has assessed you can reach it; three routes
lead to one. If you are already in treatment, your own clinician is
cheapest, ask, but budget for the queue and for explaining a request they may
have no template for. A community mental health centre is second; its intake
is built around continuing care, so expect a longer wait.

The third is an evaluation arranged for the purpose: a short screening, a
South Carolina-licensed professional, and a letter issued only where the
findings support one. It applies the test § 31-21-70(N)(2) already describes,
which is why the document travels. The one part of a Charleston tenancy that
does not turn on how many families live in your building.

## What Charleston landlords can and cannot do

**Cannot:**
- Cannot refuse a reasonable accommodation in rules, policies, practices or services where it may be necessary to give a person with a handicap an equal opportunity to use and enjoy a dwelling: S.C. Code Ann. § 31-21-70(G)(2), and 24 C.F.R. § 100.204(a) federally.
- Cannot treat a no-pets policy as the end of the conversation. A no-pets policy is a rule, and rules are what § 31-21-70(G)(2) requires be adjusted where an accommodation may be necessary.
- Cannot dismiss documentation that establishes a disability and a disability-related need. Under § 31-21-70(N)(2) such documentation "shall be deemed sufficient", the statute settles the question rather than leaving it to the landlord's taste.
- Cannot demand that the animal be registered, certified, or wearing a vest. South Carolina's own 2019 Act recorded in its preamble that no vest, marking or documentation is required for an animal to qualify, and that such things are not "a reliable indication" of anything.
- Cannot charge pet rent, a pet deposit or a pet fee for an approved assistance animal, because the accommodation is a change to a rule rather than permission to keep a pet.
- Cannot threaten a tenant with § 47-3-980 for making a housing request. That section penalises misrepresenting an animal as a service animal, expressly "does not constitute a criminal offense," and does not describe an emotional-support accommodation request under Title 31.
- Cannot coerce, intimidate, threaten or interfere with a tenant for exercising a right under the Fair Housing Law. § 31-21-80, with the Residential Landlord and Tenant Act's own § 27-40-910 alongside it.

**Can:**
- May ask the two questions § 31-21-70(N)(1) sets out: whether the person seeking to live with the animal has a disability that substantially limits a major life activity, and whether they have a disability-related need for the animal.
- May request documentation verifying the answers to those two questions, § 31-21-70(N)(2). What it may not do is keep asking after documentation that meets the statutory standard has arrived.
- May decline where the specific animal would be a direct threat to the health or safety of others or would cause substantial physical damage to the property of others. 24 C.F.R. § 100.202(d), assessed on that animal's actual conduct and history rather than its breed or weight. Note the authority: South Carolina's own threat clause at § 31-21-70(E) is written only against § 31-21-40(1) and (2), the two subdivisions that omit handicap, so it does not by its terms answer an assistance-animal request.
- May set the security deposit at any amount, because South Carolina caps none, but must itemise every deduction in writing within thirty days under § 27-40-410, on pain of treble damages.
- May fall outside §§ 31-21-40 and 31-21-60 entirely if the building holds no more than four families and the owner actually lives in one of them, § 31-21-70(A). The federal Fair Housing Act still applies on its own terms.

## How to get an ESA letter in Charleston

1. **Check that you qualify**, Answer a short screening about how your condition affects daily life in Charleston. No diagnosis paperwork needed up front. (About 5 minutes: free)
2. **Connect with a licensed professional**, You are matched with a provider licensed for South Carolina clients who reviews your situation in a telehealth evaluation. (Telehealth evaluation)
3. **Complete your evaluation**, The professional evaluates whether an emotional support animal alleviates symptoms of a condition recognized in the DSM-5. Honest evaluations, not everyone qualifies. (Most of Our Applicants Qualify)
4. **Receive your signed letter**, Your letter arrives on the professional's letterhead with their license number: the documentation South Carolina landlords may lawfully request. (Typically within days of approval)
5. **Send it to your landlord**, Submit the letter with a short reasonable-accommodation request. Pet fees, pet deposits, and breed limits no longer apply to your animal in Charleston. (Protection under FHA + state law)

## Conditions that can qualify for an ESA

No fixed government list exists. A licensed professional evaluates whether an animal alleviates symptoms of a DSM-5-recognized condition, commonly:

- Generalized anxiety disorder
- Major depressive disorder
- Post-traumatic stress disorder (PTSD)
- Panic disorder
- Social anxiety disorder
- Obsessive-compulsive disorder (OCD)
- Bipolar disorder
- Attention-deficit/hyperactivity disorder (ADHD)
- Phobias with housing impact
- Chronic stress affecting daily function

## Frequently asked questions

### My Charleston landlord lives in the building. Is my ESA request still covered?

It depends entirely on how many families the building holds, and South Carolina draws that line one unit wider than most people expect. Section 31-21-70(A) suspends §§ 31-21-40 and 31-21-60 for a dwelling whose "living quarters" are "occupied or intended to be occupied by no more than four families living independently of each other, if the owner actually maintains and occupies one of the living quarters as his residence." Both halves have to be true, four families or fewer, and the owner among them. An absentee owner of a fourplex is not inside it. At five families and above, § 31-21-70(C)(3) counts the owner of "any dwelling designed or intended for occupancy by, or occupied by, five or more families" as trading in rentals, and the chapter reaches them without qualification. Two cautions: what steps back is the state chapter alone, since the Fair Housing Act draws its own exemptions on different lines, and an exempt owner is still perfectly free to say yes.

### What can a Charleston landlord actually ask me about my emotional support animal?

Exactly two things, and unusually you can point at the statute rather than at guidance. Section 31-21-70(N)(1) prints the landlord's script in quotation marks: "Does the person seeking to use and live with the animal have a disability that is a physical or mental impairment that substantially limits one or more major life activities?" and "Does the person seeking to use and live with the animal have a disability-related need for the animal?" Subsection (N)(2) then lets the landlord ask for paperwork backing up the answers, and settles what happens next: it "shall be deemed sufficient if it establishes that an individual has a disability and that the animal in question will provide some type of disability-related assistance or emotional support." Note the grammar. The questions are permissive; the sufficiency is mandatory. Once documentation meeting that standard is in front of a Charleston leasing office, the statute has answered the question rather than left it to the office's taste.

### Can a Charleston landlord charge a pet deposit or pet rent for an approved ESA?

Not for an approved assistance animal. What § 31-21-70(G)(2) obliges a landlord to adjust is a rule, and the no-pets clause is that rule; the fee schedule hanging off it was written for pets and does not follow the animal across. That distinction is worth more in Charleston than in most of South Carolina, because the state regulates neither side of the pet ledger: nothing in South Carolina law limits the size of a security deposit, and the word "animal" does not appear anywhere in the Residential Landlord and Tenant Act, so no statute limits pet rent either. Against a $1,722 median gross rent — the highest of the state's three largest cities — that absence is expensive. What § 27-40-410 does police is the money coming back: every deduction "must be itemized by the landlord in a written notice to the tenant" within thirty days, on pain of "three times the amount wrongfully withheld and reasonable attorney's fees." Give a forwarding address in writing when you leave.

### Does South Carolina's $1,000 fake-service-animal fine apply to my ESA letter?

No, and the mismatch is not a technicality. What § 47-3-980(A) makes unlawful is for "a person to intentionally misrepresent an animal in his possession as a service animal or service animal-in-training", knowingly, and to get at something the law reserves for disabled people. A Charleston tenant asking for a housing accommodation makes no such claim. The code keeps the two categories apart in its own definitions: § 47-3-920(6) calls an emotional support animal "an animal intended to provide companionship and reassurance," and § 47-3-920(4)(b) rules that comfort and companionship are not work or tasks. Two further limits get dropped from every retelling. Under subsection (D) the violation "does not constitute a criminal offense," and nobody may be taken into custody for it save on a warrant for failure to appear or pay. Subsection (C) confines enforcement inquiries to those 28 C.F.R. § 36.302 allows: the ADA's two questions, nothing wider.

### Do I have to register my emotional support animal anywhere in Charleston?

Nowhere, because nothing exists to register with: the state operates no ESA list, issues no ESA credential, and the legislature put its view of the commercial substitutes in writing. Its own 2019 legislation carries a preamble recording that "no vest, other marking, or documentation is required for an animal to qualify as a service animal, nor are such vests, markings, or documentation a reliable indication of whether an animal is, by law, a service animal," alongside a complaint about firms selling exactly those things. Set that beside § 31-21-70(N) and the shape is plain. What the subsection asks for is proof of two facts about a person and an animal, and those facts are a clinical judgement about you, reached by someone qualified to reach it. Nothing on a merchant's checkout page produces one, and a certificate answers neither question a Charleston landlord is entitled to put.

### How long do I have if a Charleston landlord refuses the accommodation?

The refusal starts two timers of unequal length, running independently of each other. Section 31-21-120(B) requires that a filing with the South Carolina Human Affairs Commission (the body administering the chapter under § 31-21-90(A)), "must be filed within one hundred eighty days after the alleged discriminatory housing practice occurred," with one hundred days allowed for the investigation under § 31-21-120(E). The courthouse gives longer: § 31-21-140(A) provides that an action "must be commenced within one year," and "may be commenced by an aggrieved person whether or not a complaint has been filed with the commission." Missing the shorter deadline forfeits the agency, not the case. One detail decides how usable either route is: under § 31-21-120(G) the proving falls on you. Ask in writing, keep the reply, date everything. Section 31-21-80 separately outlaws coercing, intimidating, threatening or interfering with someone for exercising a right under the chapter, and that, too, is only as good as the paper trail.

### Who in Charleston can help if the request goes wrong?

Two Charleston legal-services organisations publish work that reaches a housing problem. Charleston Pro Bono Legal Services provides civil legal aid to eligible low-income residents of Charleston County at no cost, offering advice, brief preparation and direct representation, and referring more complex matters to private attorneys taking pro bono work. Charleston Legal Access is a nonprofit law firm working on a sliding scale that starts at $60 an hour depending on income and family size, serving Berkeley, Charleston and Dorchester counties, and it lists housing among its practice areas. For everything else (rental assistance, mental health services, help finding a clinician), South Carolina 211 is free, confidential and answers around the clock: dial 2-1-1, call 866-892-9211, or text your ZIP code to 211-211. None of these writes ESA letters; they are for the dispute, not the documentation.
