Can I get sued for ADA violations if I've never been asked to fix my website first?

In most of the country, yes — federal ADA Title III does not require a plaintiff to send a demand letter or offer a cure period before filing suit, so the first notice you receive can be the lawsuit itself. Florida is a notable exception: its 2021 HB 1281 law requires plaintiffs to send written pre-suit notice identifying specific barriers and give the business a cure period before a Florida-law web-accessibility claim can proceed. Outside of state-specific reforms like Florida's, waiting to be asked is not a viable strategy — nearly 95% of sued companies end up settling anyway.
