ADA (Americans with Disabilities Act) compliance requirements typically apply to public facilities and certain types of housing, depending on the circumstances. The specific regulations may vary based on your location and the nature of the remodeling project.
If you are remodeling a bathroom within your private residence, the ADA regulations may not necessarily apply unless you are subject to specific local building codes or requirements. However, it's essential to consult with your local building department or a licensed professional to determine the specific regulations that may be applicable in your area.
Regarding the door width, the ADA Standards for Accessible Design generally require doorways to have a minimum clear width of 32 inches for accessibility. If your bathroom is behind a bedroom door that is only 30 inches wide, it may not meet the standard width requirements. However, if this is within your private residence and not subject to ADA regulations, you may not be legally obligated to comply with those specific standards.
Keep in mind that accessibility is an important consideration for individuals with disabilities, and it's generally beneficial to incorporate accessible design principles whenever feasible. Even if you are not required to meet ADA standards, you might want to explore options for improving accessibility within your remodeling project. Consulting with a professional contractor or architect experienced in accessibility design can provide valuable guidance on creating a more inclusive and functional space.
