2nd Floor Ste 207 Office 939 SF $30.60 USD/SF/YR
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.

2nd Floor Ste 211 Office 706 SF $30.60 USD/SF/YR
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.

Description

21671 Gateway Center Drive is a Class B office building in the heart of Diamond Bar's prestigious Gateway Center business district. Built in 2008 and recently refreshed, the two-story, ~26,000 SF property delivers a polished, professional environment with on-site property management, controlled-access entry, 24-hour secured access, and ample surface parking. Suites are leased on a Modified Gross basis: landlord covers water, trash, property taxes, property insurance, CAM, and landscaping. Each suite has its own dedicated electric meter, so tenants run their HVAC on their own schedule — a meaningful advantage over full-service buildings in the area that shut AC off at 6 PM during Diamond Bar's hot summer months. Tenants carry their own liability insurance and bring in their own high-speed internet, with Spectrum service available throughout the building. The address sits less than a mile from the SR-57 / SR-60 interchange and is minutes from I-10 and I-210, putting Los Angeles, Orange County, and San Bernardino County within easy reach. Ontario International Airport (ONT) is roughly 15 miles east, and tenants are within walking distance of bus service and a short drive from P.F. Chang's, Olive Garden, Chili's, In-N-Out Burger, Holiday Inn, and Ayres Suites. Located in the affluent Walnut Valley submarket — median household income ~$130,000, top-tier schools, and one of Southern California's lowest crime rates — Diamond Bar is a draw for established professionals, growing tech and medical practices, and regional headquarters.
