ADA compliance means meeting the requirements of the Americans with Disabilities Act, the 1990 federal civil rights law that prohibits discrimination against people with disabilities in employment, state and local government services, and businesses open to the public. What compliance looks like in practice depends on which of those roles you occupy: an employer’s obligations differ from a city agency’s, and both differ from a retail store’s. The common thread is that qualified people with disabilities must get the same access, opportunity, and service as everyone else, and the organization is responsible for making that possible.
The law defines disability broadly. Someone is protected if they have a physical or mental impairment that substantially limits a major life activity, have a record of such an impairment, or are regarded as having one.1ADA.gov. Americans with Disabilities Act of 1990, As Amended Major life activities include walking, seeing, hearing, breathing, learning, thinking, and working, and the definition captures invisible conditions like epilepsy, diabetes, and major depression alongside visible ones. Whether an impairment qualifies is judged without factoring in medication, hearing aids, prosthetics, or other mitigating measures, and conditions in remission still count if they would be substantially limiting when active.2U.S. Equal Employment Opportunity Commission. ADA Amendments Act of 2008
Who Has to Comply
The ADA is organized into three titles, and which one applies to you determines your obligations.
Title I covers private employers with 15 or more employees and requires equal opportunity in hiring and on the job.3U.S. Equal Employment Opportunity Commission. The ADA: Your Responsibilities as an Employer Title II covers every state and local government entity, no matter how small, and requires their programs and services to be accessible.4ADA.gov. Americans with Disabilities Act Title II Regulations Title III covers private businesses that qualify as “public accommodations,” a category that sweeps in hotels, restaurants, theaters, retail stores, banks, hospitals, schools, day care centers, gyms, parks, museums, and transportation stations. If your business is open to the public and fits any of the 12 statutory categories, Title III applies regardless of your size or revenue.1ADA.gov. Americans with Disabilities Act of 1990, As Amended
Religious organizations and bona fide private membership clubs are exempt from Title III.5Office of the Law Revision Counsel. 42 USC 12187 – Exemptions for Private Clubs and Religious Organizations Those exemptions are narrower than they look. A religious organization with 15 or more employees still owes Title I employment obligations. A day care operating inside a church building remains subject to Title III as a tenant. A private club that lets nonmembers pay to use its facilities can lose its exemption because the membership restriction is no longer meaningful.
Physical Accessibility
The technical rules for buildings are set by the 2010 ADA Standards for Accessible Design, which apply to newly constructed and altered facilities used by government entities, public accommodations, and commercial businesses.6ADA.gov. 2010 ADA Standards for Accessible Design The standards are specific: ramps cannot exceed a 1:12 slope (one inch of rise per 12 inches of length), doorways must provide at least 32 inches of clear opening, and restrooms have set requirements for grab bar placement, turning clearance, and fixture heights.
Renovated portions of an existing building must meet the 2010 Standards to the extent technically feasible. Elements that already complied with the earlier 1991 Standards get a “safe harbor” and don’t need updating until you alter them. Elements the 1991 rules never covered, such as swimming pools, play areas, and amusement rides, get no safe harbor and must meet the current standards.
Barrier Removal in Existing Buildings
Even without a renovation, Title III businesses must remove architectural barriers when doing so is “readily achievable,” meaning accomplishable without much difficulty or expense.7Office of the Law Revision Counsel. 42 USC 12182 – Prohibition of Discrimination by Public Accommodations Whether something is readily achievable depends on the business’s size, resources, and the cost of the specific fix. A national chain faces a much higher bar than a family shop.
The obligation is ongoing, not a one-time audit. Improvements that weren’t affordable years ago may be readily achievable now, and businesses are expected to revisit that question. If full compliance isn’t feasible for a particular element, the business still has to take whatever partial steps it can without creating a safety hazard. When even partial removal isn’t achievable, the business must provide its goods or services through alternative methods if those alternatives themselves are readily achievable.
Website and Mobile App Accessibility
ADA obligations extend to digital spaces. The Department of Justice has long taken the position that Titles II and III apply to websites and mobile apps, and in April 2024 it issued a formal rule for state and local governments requiring their web content and mobile apps to conform to the Web Content Accessibility Guidelines (WCAG) Version 2.1, Level AA.8ADA.gov. Fact Sheet: New Rule on the Accessibility of Web Content and Mobile Apps Provided by State and Local Governments
WCAG 2.1 Level AA is the middle of three conformance tiers. In practice it requires text alternatives for images so screen readers can convey them, sufficient color contrast for readable text, full keyboard operability of every function, and captions for video content.9ADA.gov. Guidance on Web Accessibility and the ADA
Compliance deadlines for governments were extended in April 2026. Governments serving a population of 50,000 or more have until April 26, 2027. Smaller entities and special district governments have until April 26, 2028.10Federal Register. Extension of Compliance Dates for Nondiscrimination on the Basis of Disability; Accessibility of Web Content and Mobile Apps The rule carves out exceptions for archived content, PDFs and similar documents posted before the compliance date, and third-party content.
No parallel regulation exists yet for private businesses under Title III, but courts have repeatedly found inaccessible websites to violate the ADA, and settlement agreements routinely require WCAG 2.1 Level AA as the benchmark. Businesses that transact online face real litigation exposure if their sites don’t work for users with disabilities.
Reasonable Accommodations for Employees
Under Title I, employers with 15 or more employees must provide reasonable accommodations to qualified applicants and workers with disabilities.11U.S. Equal Employment Opportunity Commission. Small Employers and Reasonable Accommodation A reasonable accommodation is any change to the workplace or how a job is performed that lets someone with a disability do the work. Common examples include modified schedules, specialized equipment, an accessible workspace, qualified readers or interpreters, and reassignment to a vacant position.12U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA
When an employee requests a change, the employer is expected to begin an “interactive process,” a back-and-forth conversation to identify the essential functions of the job, understand the limitations, explore options, and settle on something workable. Employers should move promptly even if the employee never says the words “reasonable accommodation” or mentions the ADA. Delay itself can become a violation.
The one out is “undue hardship,” which the statute defines as significant difficulty or expense given the employer’s resources, size, and operations.13Office of the Law Revision Counsel. 42 USC 12111 – Definitions The bar is high for large employers. A Fortune 500 company won’t easily convince anyone that a $2,000 ergonomic workstation is a hardship. A five-person nonprofit has a more plausible argument. Even when a specific accommodation is too costly, the employer still has to consider cheaper alternatives that achieve the same result.
Service Animals and Effective Communication
A service animal under the ADA is a dog individually trained to perform a task for a person with a disability.14eCFR. 28 CFR 35.136 – Service Animals Emotional support, therapy, and comfort animals don’t qualify because they aren’t trained to perform a specific task. Staff at a business or government facility may ask only two questions: whether the dog is a service animal required because of a disability, and what task it has been trained to perform.15ADA.gov. ADA Requirements: Service Animals They cannot ask about the disability, demand documentation, or require a demonstration. No extra fee may be charged for the animal, though the handler is responsible for any damage.
Separately, public accommodations and government entities must provide auxiliary aids when needed to communicate effectively with people who are deaf, blind, or have speech disabilities. Depending on the situation that can mean a qualified interpreter, captioning, assistive listening devices, or materials in Braille or large print. The organization pays; the individual cannot be charged.
Penalties and Lawsuits
The Equal Employment Opportunity Commission enforces Title I. The Department of Justice enforces Titles II and III.3U.S. Equal Employment Opportunity Commission. The ADA: Your Responsibilities as an Employer People with disabilities can file administrative complaints or sue directly.
Private Title III lawsuits are limited to injunctive relief and attorney’s fees. A court can order the business to fix the problem and may award the plaintiff’s legal costs, but the plaintiff cannot collect damages.16Office of the Law Revision Counsel. 42 USC 12188 – Enforcement The fee provision is what drives the volume of demand letters from plaintiffs’ attorneys, because settlement often costs a business less than litigating, even a defensible case.
DOJ enforcement is more consequential. When the Attorney General brings an action, the government can seek injunctive relief, monetary damages for people harmed, and civil penalties. As of July 2025, those penalties reach $118,225 for a first violation and $236,451 for subsequent violations, adjusted periodically for inflation.17eCFR. 28 CFR Part 85 – Civil Monetary Penalties Inflation Adjustment
Tax Incentives That Offset Compliance Costs
Two federal tax provisions help absorb the cost of accessibility work. The Disabled Access Credit under Section 44 of the Internal Revenue Code lets eligible small businesses claim 50 percent of accessibility expenditures between $250 and $10,250 per year, for a maximum annual credit of $5,000. Eligibility requires either gross receipts of $1 million or less, or no more than 30 full-time employees, in the prior tax year. Qualifying expenses include barrier removal, interpreters or readers, and adaptive equipment, but not new construction.18Office of the Law Revision Counsel. 26 USC 44 – Expenditures to Provide Access to Disabled Individuals
Any business, regardless of size, can also deduct up to $15,000 per year under Section 190 for removing architectural and transportation barriers. A business that qualifies for both can use them in the same year, with the deduction applied to the portion of expenses not covered by the credit.19IRS. Tax Benefits for Businesses That Accommodate People with Disabilities For a small business making a $10,000 accessibility improvement, the two provisions together can recover a substantial share of the cost.
