The Americans with Disabilities Act (ADA) is often written in complex legal language that leaves business owners, nonprofit leaders, and even some lawyers confused about what exactly is required. This guide translates ADA regulations into plain English so you understand what the law requires, why it matters, and how to comply.
What Is the ADA and Why Does It Exist?
The Americans with Disabilities Act, passed in 1990, is federal civil rights law. It prohibits discrimination against people with disabilities in all areas of public life, including jobs, schools, transportation, and any businesses open to the public.
The basic principle: People with disabilities have the same rights as anyone else to participate fully in society. If a business or service is available to the general public, it must be available to people with disabilities on equal terms.
Before the ADA, businesses could refuse service to disabled customers, charge them more, or isolate them in separate areas. The ADA made this illegal.
The Five Main Titles of the ADA
The ADA is divided into five titles, each addressing different areas:
Title I: Employment
What it says: Employers with 15 or more employees cannot discriminate against qualified people with disabilities.
In plain English: If someone can do the job with reasonable accommodations, the employer must provide those accommodations—like flexible scheduling for someone managing a chronic illness, modified work stations for wheelchair users, or extra breaks for someone with fatigue-related disabilities.
Common accommodations:
- Modified schedules or remote work
- Accessible facilities and parking
- Assistive technology or equipment
- Modified job duties if the essential functions can be performed
- Accessible communication methods
- Leave for medical treatments
Title II: Public Services
What it says: State and local government agencies must provide equal access to their services, programs, and activities.
In plain English: Government buildings, parks, schools, libraries, and public services cannot discriminate against disabled people. They must make their facilities accessible and provide communication access.
Examples of compliance:
- Accessible government buildings
- Sign language interpreters at public meetings
- Accessible public transportation
- Large print documents for government services
- Accessible websites for government agencies
- Tactile signs and audio signals in public buildings
Title III: Public Accommodations
What it says: Private businesses open to the public must be accessible and cannot discriminate based on disability.
In plain English: Any business that serves customers (restaurants, hotels, movie theaters, stores, banks, etc.) must be accessible and provide equal service to disabled customers as to everyone else.
Covered businesses:
- Hospitality (hotels, restaurants, bars)
- Retail (stores, shopping malls)
- Transportation (airports, rental car companies, taxi services)
- Entertainment (theaters, museums, amusement parks)
- Healthcare (medical offices, hospitals, clinics)
- Professional services (law offices, accountants, dental offices)
- Education (private schools, colleges, training facilities)
- Recreation (gyms, swimming pools, golf courses)
Title IV: Telecommunications
What it says: Telephone companies must provide relay services for deaf, hard of hearing, and speech-disabled individuals.
In plain English: Anyone who uses a phone should be able to communicate. Relay services allow people who are deaf or hard of hearing to make phone calls by typing and having someone relay the conversation.
Modern requirement: This has expanded to include video relay services (VRS) where an interpreter signs to/from the deaf caller.
Title V: Miscellaneous
What it says: Various provisions including instructions on how to file complaints and remedies for violations.
Core ADA Principles: What Businesses Must Actually Do
Beyond the five titles, the ADA operates on several core principles that apply to all covered entities:
1. Physical Accessibility
What it requires:
- Accessible parking spaces
- Ramped or step-free entrances
- Accessible doors (proper width, handle type)
- Accessible restrooms
- Accessible routes through buildings
- Accessible seating and service areas
- Signage indicating accessible features
The standard: A person using a wheelchair should be able to navigate the space independently. The route should be continuous, unobstructed, and at least 36 inches wide in most cases.
2. Communication Accessibility
What it requires:
- Menus, documents, and materials in large print or braille upon request
- TTY or video relay service for telephone communication
- Sign language interpreters at meetings and events
- Real-time captioning for audio presentations
- Accessible websites
- Written materials for audio-only programs
- Staff trained to communicate with deaf and hard of hearing people
The principle: Information should be accessible to people who are blind, deaf, hard of hearing, or have cognitive disabilities that affect reading.
3. Service Animal Accommodations
What it requires:
- Allowing trained service dogs (and in some cases, miniature horses) in all public areas
- Not requiring special identification or certification
- Not isolating the handler or animal
- Treating service animals like any other customer accommodation
Important distinction: Emotional support animals and pets are not service animals under the ADA and can be excluded.
4. Reasonable Modifications to Policies and Procedures
What it requires: Changing rules when necessary to provide equal access. Examples:
- Allowing a guide dog to accompany a student to school even if pets aren't normally allowed
- Modifying dress codes for people with disabilities (e.g., allowing comfortable shoes for someone with arthritis)
- Allowing service animals at outdoor events usually restricted to humans only
- Permitting wheelchair users to sit in different seating areas at performances
- Allowing extra time for tests for students with disabilities
- Permitting someone to bring medical equipment into spaces normally requiring minimal belongings
The test: Is the modification reasonable? Can the business safely provide it without undue financial burden?
5. Auxiliary Aids and Services
What it requires: When someone has a disability affecting communication, the business must provide aids to ensure communication access. This includes:
- Sign language interpreters
- CART (real-time captioning)
- Braille materials
- Audio descriptions
- TTY devices
- Large print materials
- Oral interpretation (staff member reading aloud)
- Electronic readers that read text aloud
The cost principle: Usually, the business must provide these at no extra charge to the customer. However, if the cost is "undue burden" (causing significant difficulty or expense), the business must still provide alternative access methods.
What "Accessibility" Actually Means in ADA Terms
The ADA uses the term "accessible" in several ways, and understanding these distinctions matters:
Readily Achievable
"Readily achievable" means easy to do and not costly. When something is readily achievable, businesses must do it. For small businesses, "not costly" might mean spending up to a few hundred dollars. For large corporations, it could mean several thousand dollars.
Examples of readily achievable actions:
- Installing a ramp at an entrance
- Adding grab bars to a bathroom
- Repositioning a service desk to be accessible
- Providing staff to assist with opening doors
- Providing written materials in large print
Undue Burden/Undue Hardship
If an accommodation would cause significant expense or difficulty—disproportionate to the business's resources—it might be considered an "undue burden." However, this is rarely accepted as an excuse. Businesses must still provide alternative access.
Important: Cost to the disabled person cannot be passed on. If a business says something is an undue burden, they must still provide the service in an alternative way.
Directly Related
An accommodation must be "directly related" to the disability and the service being provided. A restaurant can't refuse to provide a menu in large print just because the restaurant doesn't normally provide menus in multiple formats—this is directly related to the service of serving food.

Key ADA Rules About Who Must Comply
Business Size
There's no size requirement for ADA Title III compliance for most businesses. Even a one-person business open to the public must comply with the ADA.
Exception: Businesses with fewer than 15 employees are exempt from Title I (employment) provisions, but must still comply with accessibility requirements for customers (Title III).
Type of Organization
Must comply:
- For-profit businesses
- Nonprofits
- Government agencies
- Educational institutions
- Any entity providing goods or services to the public
Cannot claim exemption based on:
- Being too small
- Being nonprofit
- Being located in a residence (if open to public)
- Offering services only to members
- High costs (cost alone doesn't justify non-compliance)
What Gets Enforced and How
