Mark III Construction Signs Agreement for Sacramento-Area Headquarters at McClellan Park

McCLELLAN PARK, Sacramento County — McClellan Park’s management announced in February 2026 that Mark III Construction had signed an agreement for a new headquarters location within the business park.

The developer’s news listing describes the decision as part of continuing industrial and business occupancy at the former military air base. McClellan’s transformation into a mixed aviation and industrial district has created space for contractors, manufacturers, services and other employers.

The announcement confirms an agreement, but does not independently establish the company’s exact relocation date, employee count or job creation. Those details should be verified with the company before being described as completed outcomes. Economic-development announcements are also distinct from local permitting and traffic access changes.

What residents and businesses should know

Residents who live near industrial streets can monitor county land-use records for site-specific modifications. Job seekers should use the employer’s official careers channel rather than assume that signing a lease automatically creates open positions.
