Musical bands and performers have always had a difficult time securing space for rehearsing their acts and numbers, and starting a business that rents rehearsal space to musicians by the hour, day, week or month is a fantastic new enterprise to get rolling. Ideally, the business will be established on leased premises in an industrial building so that noise won't be a concern or become a problem. Additionally, the spaced that's leased for the rehearsal space should also be subdivided into a few smaller rehearsal rooms to accommodate more than one customer at a time. Current rental rates for rehearsal rooms start at $10 per hour and can go much higher depending if any equipment and PA systems are supplied and included in the rent.
Typical customers will be anyone in the music industry--from musicians to singers to music producers.
