    Physical Access to Businesses and the Barrier Removal Duty

    The ADA asks different things of an old storefront and a new one. This sets out what an existing business must remove, what a new or altered space must be built to, and where the line falls.

    Federal rule 7 min read Public places For customers turned away by a step or a narrow door, small business owners and landlords, tenants signing a commercial lease

    The short answer

    An existing business must remove architectural barriers when doing so is readily achievable, meaning easily accomplishable without much difficulty or expense. Anything newly built or altered has to meet the full federal design standards outright, with no cost excuse available.

    An abstract figure of numbered rules standing in for the questions this page answers about physical access to businesses and the duty to remove barriers.

    Which businesses have to be accessible at all?

    Almost all of them. Title III of the Americans with Disabilities Act covers places of public accommodation, a category that runs from restaurants, hotels, and shops through doctors' offices, gyms, theaters, day care centers, banks, and law offices. Size does not create an exemption. A single-chair barber shop is covered on the same terms as a department store, though what each owes differs sharply.

    Two categories sit outside. Private clubs that genuinely restrict membership and religious organizations operating their own facilities are not covered by Title III, although a church that rents its hall to a covered business can pull the tenant into coverage. Employers are covered under a different part of the ADA, and government buildings under another one again.

    Coverage is not the same as a duty to rebuild. What a covered business owes depends entirely on whether the space is existing, altered, or new, and that is the distinction most arguments turn on.

    It also helps to know what this duty is not. Barrier removal deals with the built environment: steps, widths, heights, surfaces, and routes. It does not cover how staff talk to a customer, which is a separate obligation with its own standard, and it does not cover policies such as a no-animals rule, which are handled as modifications to practice. A business can satisfy one of these and violate the others without noticing.

    What does readily achievable actually mean?

    For a building that already exists, the standard is barrier removal that is readily achievable, which the statute defines as easily accomplishable and able to be carried out without much difficulty or expense. It is not a fixed dollar figure and never has been. It scales with the business.

    The factors that matter include the cost of the specific change, the financial resources of the site, the number of employees, the effect on operations, and the resources of any parent corporation. The same $4,000 ramp can be readily achievable for a regional chain and genuinely out of reach for a sole proprietor in a bad year. Resources are judged at the level of the entity, not just the till.

    The duty is also continuing. A business that could not afford a change in a lean year is expected to look again as circumstances improve. Nothing about the standard makes a one-time refusal permanent, and a refusal recorded in writing is a useful thing to raise again later.

    Federal tax provisions exist to soften the cost. A small business meeting the size and revenue tests can claim a credit against a portion of its access expenditures, and a separate deduction is available for removing architectural barriers. Neither one changes the legal standard, but both change the arithmetic a business does when it decides whether a change is affordable, and it is fair to mention them in a letter.

    Where should a business start, and in what order?

    Federal regulations set a priority order, and it is a practical one. Access is worthless if a customer can reach the counter but never got through the door, so the sequence starts at the outside and works inward.

    1. Getting in. Accessible parking, a route from the sidewalk or lot, a usable entrance, and a door that opens with reasonable force.
    2. Getting to the goods and services. Aisle width, level changes inside, counters and tables at a usable height, and access to the areas where the business is actually conducted.
    3. Restrooms. Where public restrooms exist, making at least one usable, including door width, clear floor space, and grab bars.
    4. Everything else. Drinking fountains, public telephones, and remaining features.

    Working out of order is a common and expensive mistake. A business that spends its budget on a beautifully accessible restroom while leaving a step at the front door has bought something no new customer can reach. The order exists because access is sequential: each stage is worthless without the one before it.

    Cheap fixes near the top of the list beat expensive fixes near the bottom. Rearranging tables, repositioning a display rack, adding a doorbell with a posted sign, installing a lever handle, painting an accessible parking space, and adding a portable ramp are the kinds of changes that get treated as readily achievable in most circumstances.

    Is the standard different for new buildings and remodels?

    Completely different, and this is the part small businesses most often get wrong. Anything designed and constructed for first occupancy after the ADA's construction deadline must comply with the federal design standards in full. There is no readily achievable test and no cost defense. If it is new, it complies.

    Alterations are treated the same way for the part being altered. If you remodel a restroom, that restroom has to meet the standards. If you alter an area containing a primary function of the business, such as the dining room or the sales floor, the path of travel to that area, including restrooms, telephones, and drinking fountains serving it, has to be made accessible as well, subject to a disproportionate-cost limit set by regulation.

    Altering part of a spaceFull design standards for the altered partNo
    Altering a primary function areaStandards plus an accessible path of travelOnly via the disproportionate-cost cap
    New constructionFull design standards throughoutNo

    What if a physical change genuinely cannot be made?

    The duty does not evaporate. Where removal is not readily achievable, the business has to make its goods and services available through alternative methods, if those alternatives are themselves readily achievable. Curbside service, home delivery, bringing merchandise out to a customer, relocating an activity to an accessible room, or retrieving items from an unreachable shelf all qualify.

    Alternatives have limits. They cannot be used as a substitute for a fix that is achievable, they cannot be offered on worse terms, and they cannot cost the customer more. A restaurant with a step at the door that offers to hand food out the doorway has done something; a restaurant that could install a $200 threshold ramp and offers the doorway instead has not.

    Communication barriers follow a separate track with its own rules about aids and services, so a business that has handled the ramp still needs to think about how it communicates with customers who are deaf or blind. The two duties sit side by side and neither one satisfies the other.

    Worth knowing

    Leases can shift who does and pays for the work, and courts will enforce that allocation between landlord and tenant. It does not change anything for a customer, who may pursue either one. If you are signing a commercial lease, the access clause deserves the same attention as the rent.

    What can a customer do about an inaccessible business?

    Start with the simplest step, because it works more often than people expect. Many owners have never had the barrier pointed out and do not know that a $150 fix exists. A short written note describing the barrier, what happened when you tried to get in, and the change you are asking for gives the business a chance to act and gives you a record if it does not.

    If that goes nowhere, a complaint to the Department of Justice is free and requires no lawyer. Federal enforcement under Title III generally produces injunctive relief, meaning an order to fix the barrier, rather than damages to the individual. Some state and local laws add monetary remedies that federal law does not, which is why a state civil rights agency is often worth checking alongside the federal route. The mechanics of choosing a forum are covered in more detail in the walkthrough on where a disability discrimination complaint goes.

    Document what you found. Photographs with something of known size in the frame, a note of the doorway width, and the name of whoever you spoke to are worth more than a paragraph of description. The same habit helps in other settings where access is refused, including the process for challenging a denial of equipment you depend on, where contemporaneous notes carry real weight.

    What to remember

    1. Readily achievable is a sliding scale that grows with the resources of the business and its parent company.
    2. New construction and alterations are held to the design standards in full; cost is not a defense there.
    3. A landlord and a tenant can allocate the work by lease, but both remain answerable to the public.
    4. When a physical fix is genuinely not achievable, the business still owes an alternative method of access.
    5. Barrier removal has a priority order that starts at the entrance and moves inward, not at the fanciest fix.

    Other questions people ask

    Are historic buildings exempt from access requirements?

    No, but the standards bend where a change would threaten the features that make a building historic. The usual approach is to find an alternative that preserves those features, such as a ramp at a secondary entrance or access to a display on the accessible floor. Exemption is narrow and specific, not a blanket pass for old buildings.

    Does a business have to build a restroom it never had?

    Barrier removal generally addresses existing features rather than requiring wholly new ones. If a public restroom exists, making it usable is squarely on the list. If a business has no public restroom at all, the ADA does not usually force it to create one, though building and plumbing codes may.

    Can a business charge a customer for the cost of access?

    No. A public accommodation cannot pass along the cost of accessibility measures to the people who need them through a surcharge, a higher price, or a separate fee. Costs can be spread across the whole customer base as ordinary business expenses, but not billed to a disabled customer as such.
