Well-maintained ±750 SF first-floor office suite in a professional Diamond Bar location at 402 S Prospectors Road, Suite C. The unit features two generously sized rooms, a private bathroom, and an open, flexible layout that accommodates a wide range of uses — from professional services and medical or wellness practices (most recently operated as a skincare clinic) to creative studios, consulting offices, and small boutique businesses. The asking rate of $2.20/SF is structured as a Modified Gross lease and includes electric, gas, water, and trash at a flat rate — a meaningful cost advantage over comparable Diamond Bar suites where utilities are billed separately. The landlord covers property taxes, property insurance, landscaping, and common area maintenance. The tenant is responsible for liability insurance covering the interior of the suite, plus telephone, internet, and cable. Parking is ample, with an on-site lot and additional street parking directly in front of the unit, making access easy for both staff and clients. Diamond Bar offers convenient access to the 57 and 60 freeways, a strong professional tenant mix, and steady daytime traffic. Available immediately. Showings by appointment.
