Overview

This property offers office suites for lease with a mix of smaller and larger configurations, including suites sized at 431sf and 948sf. The building was fully renovated in 2007, with electrical and air handling brought up to code. The space can support traditional office use, and if plumbed, the suites can be used for medical use in connection with a CUP.

The property is positioned adjacent to the intersection of Seal Beach Boulevard and Westminster Avenue, with nearby access to an on/off ramp to the I-405 Freeway. Parking is supported by 56 spaces on-site, representing a 5:1000 parking ratio, and the building also has a reciprocal parking agreement in perpetuity with the adjacent Seal Beach Village Plaza.

Management and tenanting are already oriented toward professional and healthcare services, with long-term occupants on the first floor that include a periodontist and other wellness, insurance, and healthcare-related practices. The owner currently occupies the second floor and has one small space available, identified as Suite 102. This combination of renovated building systems, flexible suite sizes, and strong parking support can fit medical operators and other professional service users seeking an established healthcare-oriented environment.
