Show HN: 92% of US city websites fail Ada accessibility

92% of US city websites contain critical accessibility barriers that lock residents out of essential services like permit applications and tax payments, with platform choice (CMS vendor) being the strongest predictor of compliance risk—CivicPlus sites fail 3x more often than Granicus alternatives. Despite average scores of 93/100, 42% of cities miss post-deadline legal obligations under ADA Title II, with 45% failing the most-litigated WCAG criterion (Name, Role, Value) and nearly a quarter of sites blocking accessibility audits entirely. The compliance gap is neither insurmountable nor uniform: 58% of cities achieve zero critical barriers, and 11 sites achieved perfect scores, demonstrating that accessible government digital services are operationally achievable.
