The ADA Demand Letter 30-Day Response: What to Do in the First Week

The letter arrives by email or certified mail, cites the Americans with Disabilities Act, lists barriers on your store, and asks for a response within thirty days. It feels like a lawsuit, and it is designed to feel that way, but it is a demand letter, which is a negotiation opener with a clock on it.

The first week decides how the next three months go, and the work in that week is smaller than people think: a lawyer, a test, and a plan.

Day one: do not reply, do not fix, do not panic

Do not reply the same day. A same-day reply written in panic usually admits things the store does not need to admit, promises a timeline it cannot meet, or argues with the letter, and all three make the negotiation harder. The thirty-day clock is for the response, not for the fix, and the first day is for reading the letter carefully, not answering it.

Do not start fixing either, not yet. Random fixes made before the barriers are understood can break other things, and a fix applied without documentation is a fix the store cannot prove. The first step is understanding what the letter actually claims, which barriers it lists, and whether those barriers are real on the live site.

Send the letter to a lawyer who handles ADA website cases, the same day it arrives. ADA defense is a specialty, and a general business lawyer will cost more while knowing less. The lawyer's first job is to verify the claims, check the plaintiff firm's history, and draft the response. The store's first job is to stop touching the site until the lawyer has seen it.

Days two to seven: test, scope, and plan

Test the cited barriers yourself, with a keyboard and a screen reader, on the live site. Some barriers in demand letters are real and some are boilerplate, copied from a template and applied to a store that does not have them. A barrier that does not exist on the live site is a point in the store's favor, and it is worth knowing before the response is written.

Scope the real barriers by risk, starting with the checkout, then navigation, then product pages, because that is the order a plaintiff's tester will recheck. Get a realistic timeline from whoever will do the work, and add time for testing, because a fix that is not tested is a fix that fails the recheck.

The response letter goes out before day thirty, and it should do three things: acknowledge the letter, state the plan with the order and the timeline, and open the negotiation. A credible plan with a start date is the strongest response a store can send, because it shows the store is fixing the problem rather than ignoring it or arguing about it.

The two mistakes that cost the most

Silence is the first. A store that does not respond within thirty days is telling the plaintiff's firm that a lawsuit is the only way to get attention, and the firm will take the hint. The filing fee for the plaintiff is small, and the cost of defending a filed case is an order of magnitude larger than settling a letter.

The second is the instant-fix purchase, usually an overlay widget bought the day the letter arrives. It does not fix the barriers, the plaintiff's firm knows it, and the purchase becomes evidence that the store chose a cosmetic fix over a real one. The money is better spent on the first checkout fix, which is the barrier that matters most.

Frequently asked questions

Is an ADA demand letter the same as a lawsuit?

No. It is a demand for a response and a negotiation opener. A lawsuit comes later, if the store does not respond or the negotiation fails.

Should I reply to the demand letter myself?

No. Send it to a lawyer who handles ADA website cases the same day it arrives. A same-day reply written in panic usually admits things or promises timelines the store cannot meet.

How long do I have to respond?

Most letters ask for a response within thirty days. That is the deadline to respond with a plan, not to finish all fixes.

What if some barriers in the letter are not real on my site?

Test them yourself with a keyboard and screen reader. Barriers that do not exist on the live site are a point in your favor, and your lawyer should know about them before drafting the response.
