In recent years, there have been a growing number of lawsuits filed in the California against companies for having websites that are allegedly not accessible to people with disabilities, particularly visual impairments. These lawsuits argue that inaccessible websites violate the Unruh Act by preventing full and equal access to the goods, services and advantages that the business offers through its website.

Some key requirements for business websites under the Unruh Act include:

- Ensuring website compatibility with many screen reader software that reads the websites for the visually impaired. This includes providing textual descriptions and captions for the images, videos and also audio files.

- Ensuring all functions and navigation can be accessed via the keyboard commands without requiring the use of a mouse. This aids those who cannot use the mouse.

- Avoiding use of the flashing or blinking elements that can trigger seizures.

- Allowing users to adjust the color contrast and also the text size for readability.

- Providing easily identifiable section headings using the HTML markup. Headings allow screen reader users to navigate the web pages more easily.

- Ensuring online forms are structured properly so screen readers can navigate and interpret them appropriately.

- Providing text transcripts for the audio and video content on the websites.

Essentially, the companies should ensure their websites are designed with accessibility in the mind from the start. Performing just a basic compliance check of a website's accessibility can help businesses avoid potential legal exposure under California's Unruh Act. Often, only the minor adjustments required to improve the accessibility.
