Seventh Street began working on the acquisition of a 2.3 acre development site adjacent to its Alderson Business Park (see full project description below) in January 2020.  Despite City of Irwindale office closures due to the COVID-19 pandemic, Seventh Street closed escrow as promised and completed entitlement, design, and construction in record time.  The 42,700 square-foot building was fully leased upon completion in April 2021.  The building features 28’ clear heights, ESFR sprinkler system, a large fenced yard with automated gate, and 5,570 square feet of office space on two stories.  To commemorate the 60-year history of AMVETS Post 113 at this location, a unique American Veterans Memorial featuring a World War II Howitzer Anti-Tank gun is displayed at the project site

In 2013, Seventh Street purchased 25 acres located on the west side of the 71 Freeway at Mission Boulevard in Pomona for development as the fourth phase of the Mission 71 Business Park. Seventh Street entitled the project and commenced construction in August 2014 on four new state-of-the-art manufacturing and distribution buildings.   The buildings feature Freeway Signage, 30-foot clear heights (with the largest of the four buildings at 32-foot clear), ESFR sprinkler systems, large secure, all-concrete truck courts, and 6,000 square feet of high-quality two-story offices in each building. Construction was completed in the fall of 2015 and all four buildings were occupied upon completion to users Konica Minolta, Kavo Kerr, and Nu Sign.

After the successful completion of Phase I of Mission-71 Business Park, Seventh Street Development completed full entitlements and installed infrastructure improvements for the 3-building, 215,000-square-foot Phase II. Project challenges that were successfully resolved include complicated freeway right-of-way and temporary easement issues with the City of Pomona and CalTrans, relocation of public water lines, and the procurement of a Conditional Use Permit from the City of Pomona. The buildings were completed in the Summer of 2014 and were immediately occupied by Owner-users.

Huy Fong Foods, one of the largest and best-known manufacturers of hot sauces in the world, selected Seventh Street Development in February 2008 as development manager for its new headquarters and food manufacturing facility. The building at 655,000 square feet is the largest building ever constructed in the City of Irwindale and features sustainable design elements. Seventh Street identified the 23-acre site owned by the City of Irwindale Redevelopment Agency and negotiated a development agreement with the City. Construction began in October 2010 and the project was completed in the Fall of 2011. Seventh Street was responsible for all aspects of the project including site selection and acquisition, entitlement, design, permitting, and construction management.

The Speedway Business Park is a 4-acre master-planned industrial park located near the intersection of the 605 and 210 Freeways. The project successfully integrates the City of Irwindale Design Guidelines into an architecturally distinctive mission-style park consisting of four freestanding buildings totaling 85,000 square feet. Seventh Street Development was selected by the City of Irwindale through a competitive selection process to develop this irregular site which is just north of the Irwindale Speedway and adjacent to active mining operations. The buildings were completed near the end of 2006 and the project was fully occupied in early 2007.
