21671 Gateway Center Dr Bureau | 66–153 m² | À louer | Diamond Bar, CA 91765

Suite 207 is a 939 SF second-floor office at 21671 Gateway Center Drive with the building's most impressive outlook — a freeway-facing window line overlooking the SR-57 / SR-60 corridor, offered on a Modified Gross lease at $2.45/SF/MO. The elevated position brings in abundant natural light and gives clients and staff a commanding view that first-floor space simply can't match — the kind of suite that photographs well and shows even better in person. Central HVAC runs on a dedicated electric meter, so the tenant controls climate around the clock — a real advantage over full-service buildings in the area that shut AC off at 6 PM during hot Diamond Bar summers. The landlord covers water, trash, property taxes, property insurance, CAM, and landscaping; tenant carries liability insurance, electric, and high-speed internet (Spectrum available throughout the building). Building amenities include on-site property management, controlled-access entry, 24/7 secured access, and abundant surface parking. Less than a mile from the SR-57 / SR-60 interchange with quick connections to I-10, I-210, Orange County, and San Bernardino County, Suite 207 suits a professional services firm, medical practice, or regional team that wants a polished Tri-County address with a view to go with it.

Suite 211 is a 706 SF second-floor office at 21671 Gateway Center Drive, positioned on the quiet side of the building away from the freeway corridor — offered on a Modified Gross lease at $2.45/SF/MO, which pencils to just $1,729.70 per month. The right-sized footprint and calm setting make it a natural fit for tenants whose work depends on a low-distraction environment: therapists and counselors, attorneys and CPAs, consultants, and any solo practitioner or small team that wants a professional Gateway Center address without paying for space they won't use. Central HVAC runs on the suite's own dedicated electric meter, so the tenant controls heating and cooling around the clock — unlike full-service buildings in the area that shut climate control off at 6 PM during Diamond Bar's 100°+ summer stretches. The landlord covers water, trash, property taxes, property insurance, CAM, and landscaping; tenant carries liability insurance, electric, and high-speed internet (Spectrum available throughout the building). Tenants enjoy on-site property management, controlled-access entry, 24/7 secured access, and ample surface parking for staff and visiting clients. Less than a mile from the SR-57 / SR-60 interchange with fast connections to I-10, I-210, Orange County, and San Bernardino County, Suite 211 delivers a polished Tri-County address at one of the lowest monthly price points in the Gateway Center.
