ADA Title II vs Title III comes down to one question: who runs the thing? Title II binds public entities, which the statute defines as "any State or local government" and "any department, agency, special purpose district, or other instrumentality of a State" (ADA.gov). Title III binds private entities that operate a place of public accommodation, and the statute lists twelve categories of them, including hotels, restaurants, doctors' offices and private schools (ADA.gov).
That distinction is not cosmetic. Under ADA Title II you have a named technical standard and a date: WCAG 2.1 Level AA, by April 26, 2027 or April 26, 2028 depending on the population you serve (ADA.gov). Under Title III you have neither. The Justice Department "does not have a regulation setting out detailed standards" for business websites, and says businesses "have flexibility in how they comply" (ADA.gov). The remedies differ too, and so does the kind of organization that can be under both at once. Below is how to place yourself.
Who does ADA Title II cover?
State and local government, at every level and every size. The definition of a public entity in 42 U.S.C. § 12131 is broad on purpose: a State or local government, any department, agency, special purpose district or other instrumentality of one, plus the National Railroad Passenger Corporation and commuter authorities (ADA.gov).
There is no small-entity carve-out. DOJ puts it in one sentence: "Under Title II, all state/local governments must follow the ADA regardless of their size" (ADA.gov). A township with four employees is covered the same way a state agency is, and what it owes is that people with disabilities get "an equal opportunity to benefit from all of their programs, services, and activities" (ADA.gov).
In practice that catches public school districts, public universities, transit agencies, county courts, public libraries, and the special districts that run water, fire, and mosquito abatement. If your budget comes from a legislature or a local tax levy, start with Title II.
Who does ADA Title III cover?
Private businesses and nonprofits that serve the public. DOJ's own description is "Businesses, including nonprofits, that serve the public (also called public accommodations)" (ADA.gov). The nonprofit part surprises people. A charity is not exempt because it is a charity.
The statute names twelve categories in § 12181(7). They run from places of lodging and food service through sales and rental establishments, transportation stations, places of recreation and places of education, and the list is more specific than most summaries let on: "service establishments" is spelled out as including banks, law offices, pharmacies, hospitals and funeral parlors (ADA.gov).
Two exclusions matter. Religious organizations and private clubs are outside Title III, though DOJ notes that charging a membership fee does not by itself make you a private club (ADA.gov). Commercial facilities such as office buildings, warehouses and factories sit in a narrower box: they "need only comply with requirements of the ADA Standards for Accessible Design" for construction and alterations (ADA.gov).
What are the actual differences between Title II and Title III?
| Title II | Title III | |
|---|---|---|
| Who it binds | State and local government, any size | Private businesses and nonprofits serving the public |
| Statutory definition | Public entity, 42 U.S.C. § 12131 | Place of public accommodation, 42 U.S.C. § 12181(7) |
| Web and app standard | WCAG 2.1 Level AA, by regulation | None named by regulation |
| Compliance date | April 26, 2027 (population 50,000+); April 26, 2028 (under 50,000 and special districts) | No dated web deadline |
| Existing facilities | Program accessibility, limited by undue financial and administrative burdens | Barrier removal where "readily achievable" |
| Private plaintiff can get | Remedies under section 505 of the Rehabilitation Act (42 U.S.C. § 12133) | Injunctive relief under 42 U.S.C. § 2000a-3(a) |
| DOJ can seek | Investigation and voluntary compliance agreements | Monetary damages for aggrieved persons and civil penalties |
The existing-facilities row changes day-to-day decisions. A city measures a request against whether it would impose undue financial and administrative burdens on its program as a whole. A restaurant measures it against whether removal is readily achievable, meaning easily accomplished without significant difficulty or expense (ADA.gov). Two different tests, and they come out differently for the same physical problem.
Can both titles apply to the same organization?
Yes, and this is the case people get wrong most often. When a private company runs a government program under contract, the government keeps its Title II duty and the company picks up a Title III duty of its own.
DOJ's Title II preamble gives the example directly: "A State is obligated by title II to ensure that the services, programs, and activities of a State park inn operated under contract by a private entity are in compliance with title II's requirements. The private entity operating the inn would also be subject to the obligations of public accommodations under title III of the Act" (ADA.gov archive).
Swap the inn for a permit-application portal and nothing changes. The county answers under Title II, on the WCAG 2.1 AA rule and its dates. The vendor answers under Title III for its own site, and answers to the county in the contract. Neither gets to point at the other.
A few placements worth memorizing, because the same institution type falls on both sides:
- A public university is Title II. A private university is Title III, as a "place of education" under § 12181(7)(J).
- A county hospital is Title II. A private physician's office is Title III, as a service establishment under § 12181(7)(F).
- A federal agency is neither. Federal ICT runs on Section 508, which points at WCAG 2.0 Level A and AA and has been in force since 2018.
Do the web accessibility requirements differ?
Sharply, at least on paper.
Title II has a rule with a version number in it. The 2024 web rule sets WCAG 2.1 Level AA as "the technical standard for state and local governments' web content and mobile apps," with compliance dates of April 26, 2027 for entities serving 50,000 or more people and April 26, 2028 for everyone else, after DOJ extended both by a year in April 2026 (ADA.gov; Federal Register, 91 FR 20902). Five categories are excepted, including archived content and third-party content the government does not post. Even inside those, DOJ says the general duties survive: "even when web content or content in mobile apps does not have to meet WCAG 2.1, Level AA," entities still owe effective communication and reasonable modifications (ADA.gov). I wrote up the date change in what the Title II deadline extension actually changed.
Title III has no such rule. DOJ's web guidance says the department "does not have a regulation setting out detailed standards" and that businesses have flexibility, while pointing at WCAG as one of the "existing technical standards" that "provide helpful guidance" (ADA.gov).
Here is my opinion after reading a lot of these documents: that flexibility is worth less than it sounds. "No named standard" means nobody tells you the target in advance, and nobody has agreed you hit it either. WCAG is still what a settlement or a procurement questionnaire reaches for, because a measurable thing is the only thing you can write into an agreement. Build to WCAG 2.2 Level AA either way. It is a superset of 2.0 and 2.1, so one target covers the Title II rule, the Section 508 standard, and whatever a Title III complaint cites. The version question has its own post: does the ADA require WCAG, and which level.
How does enforcement differ?
The remedy a private plaintiff can win is the biggest split, and it is badly reported.
Under Title III, a private plaintiff gets the remedies of 42 U.S.C. § 2000a-3(a), which is injunctive relief: an order to fix the thing, plus attorney's fees (Cornell LII, 42 U.S.C. § 12188). Federal money changes hands only when the Attorney General brings the action. There a court may award "monetary damages to persons aggrieved when requested by the Attorney General," and may assess a civil penalty the statute caps at $50,000 for a first violation and $100,000 for later ones, with punitive damages excluded by § 12188(b)(4) (Cornell LII). The penalty figures quoted at businesses describe that DOJ action, not a private suit.
Under Title II, § 12133 routes plaintiffs to the remedies of section 505 of the Rehabilitation Act, and complaints also go to DOJ or to a designated federal agency for investigation (ADA.gov).
State law changes the arithmetic for Title III entities. California is the clearest example: Civil Code § 51(f) makes a violation of the federal ADA "also constitute a violation of this section," and § 52(a) sets damages at up to three times actual damage "but in no case less than four thousand dollars ($4,000)" (California Legislative Information, § 51; § 52). The federal picture alone will not tell a California business what it is looking at.
What should you do once you know your title?
The same engineering work, on a different clock. Title II gives you a dated target, so plan backward from April 2027 or April 2028, and inventory what the rule counts as web content: PDFs and other conventional electronic documents as well as pages and mobile apps. The five exceptions are narrower than teams assume, and effective communication still applies inside them.
Title III gives you no date, which means you set your own. WCAG 2.2 AA, prioritized by what blocks a task rather than by what a scanner reports loudest.
Either way, start by finding out what is broken. An automated scan finds the machine-detectable failures quickly: inputs with no accessible name, contrast below 4.5:1, images with no text alternative, focus order that jumps out of a modal. That is the layer complaints cite first and the layer you can clear in a sprint.
It is not the whole job, and I would rather say so than sell you a shortcut. Automated testing catches roughly 30 to 57% of issues depending on the study, with Deque's analysis of its own rule set landing at 57% (Deque). No scanner, ours included, can tell you whether an error message makes sense read aloud, or whether a custom date picker behaves the way a keyboard user expects. Full conformance needs a human review. Use the WCAG checklist for the criteria a tool cannot answer.
FAQ
Is my nonprofit under ADA Title II or Title III?
Title III, in almost every case. DOJ describes public accommodations as "Businesses, including nonprofits, that serve the public," so a nonprofit museum or social service center is covered under 42 U.S.C. § 12181(7) (ADA.gov). Title II applies only if you are a government entity or an instrumentality of one. Religious organizations are excluded from Title III entirely.
Does ADA Title III have a website compliance deadline?
No. DOJ has not issued a web rule for Title III entities and "does not have a regulation setting out detailed standards" (ADA.gov). The nondiscrimination and effective communication duties apply now, and have since 1992. The April 2027 and April 2028 dates in the news belong to Title II only.
Can a private company be covered by ADA Title II?
Indirectly, yes. A public entity cannot contract its Title II obligations away. DOJ's example is a State park inn run under contract, where the State stays responsible under Title II and the operator is separately subject to Title III (ADA.gov archive). For a software vendor this usually arrives as an accessibility clause in the contract.
Are public universities under Title II or Title III?
Public universities are Title II, as instrumentalities of a state. Private universities are Title III, listed in § 12181(7)(J) as places of education (ADA.gov). Both also carry Section 504 duties if they take federal financial assistance, which is a separate statute with its own complaint route through the Department of Education.
See where your site stands under either title
The title you fall under sets your deadline and your paperwork. It does not change what a screen reader hits on your booking form. The first step is the same for a county and for a hotel chain: get the WCAG failures on your real pages with the selector for each one, then fix what blocks a task before what looks untidy. Run a free accessibility scan and work from evidence rather than from a title number.
