According to regulations, what is prohibited in residential cosmetology shops?

Shared entrances with residences are prohibited in residential cosmetology shops primarily for health and safety reasons. This regulation aims to ensure a clear separation between personal living spaces and commercial operations. Such separation helps to maintain professional standards and hygiene, reducing the risk of contamination or exposure to clients and employees in a business setting. Ensuring that a cosmetology shop has its own dedicated entrance helps to uphold the integrity of the beauty services provided and promotes a more professional environment.

While other options might seem relevant depending on context - for instance, multiple service types may be allowed, and separate restrooms can often be accommodated within regulations - the specific prohibition against shared entrances directly addresses the concern of blending a commercial space with a private residence. Using natural light is also typically acceptable in these environments, promoting an inviting atmosphere without conflicting with the regulatory framework.
