You cannot establish height or weight standards that discriminate against protected classes.
The California Fair Employment and Housing Act (FEHA) regulations acknowledge that height and weight restrictions can have an adverse impact on individuals based on their national origin. For more information, See National Origin Discrimination and Gender, Sex, and Gender Identity and Expression.
In addition, severe obesity may be a protected disability under the Americans with Disabilities Act or FEHA. For more information, see “Obesity as a Disability” in Examples of Disabilities.
Check local ordinances where you conduct business or where employees are located to determine if the local government has passed regulations about height and weight standards.
