The garage at 29, Fulwood Avenue, will be converted into a hairdressing salon.
A report by council planners states: "It is evident that the use would provide a local service, which would negate those using it, from nearby having to travel further afield.
"The development has positive benefits in terms of employment generation and being in a location that would serve the local community."
The report goes on: "It is noted there are no hours of opening specified in the application but would consider that hours need to be restrained due to the residential location.
"It is accepted that the sheer size of the premises would restrict the number of patrons involved."
