402 S Prospectors Rd, Unit B — Diamond Bar | ±600 SF | $1,500/month Well-maintained ±600 SF suite in a professional Diamond Bar location. The space is already divided into private rooms with its own private bathroom in-unit — a layout that would cost a new tenant real time and money to build from scratch. Most recently operated as a nail salon, the suite is well suited to medical and wellness practices, aesthetics and skincare, therapy and counseling, acupuncture or massage, and any professional service business that needs private client rooms. Rent is $1,500 per month, all-in, including electric, gas, water, and trash. Landlord covers property taxes, property insurance, landscaping, and common area maintenance. Tenant carries liability insurance for the interior plus telephone, internet, and cable. Parking is ample, with an on-site lot and street parking directly in front of the unit. Convenient access to the 57 and 60 freeways. Available immediately, showings by appointment.
