Marcus & Millichap is excited to present an outstanding investment opportunity for the acquisition of a prime 51,608-square-foot office building located at 3179 Temple Avenue, Pomona, California, conveniently positioned just off the 57 Freeway. This well-maintained, single-tenant office property is fully occupied by the County of Los Angeles – Child Support Services Department, a reliable government tenant that has occupied the space since 2014. Previously, the Department operated out of smaller, less accessible locations: 222 N Indian Hill Boulevard for 20 years and 1550 S. Garey Avenue for 12 years. The current location offers superior accessibility, with excellent freeway proximity and ample on-site parking, ensuring ease of access for both employees and visitors. The building has undergone extensive capital and tenant improvements totaling approximately $250,000, which include a new roof, upgraded exterior LED lighting, new south-facing awnings, a replaced condenser coil, fresh interior paint, enhanced parking lot coating, improved lighting, and upgraded exterior security cameras and monitors. Additionally, the property is set to receive a state-of-the-art solar photovoltaic (PV) system, with an estimated installation cost of $545,000. This solar system, which is included in the sale, will provide significant long-term benefits, including an estimated $358,075 in incentives for the buyer and approximately $2.775 million in electricity savings over the next 25 years, according to a proposal from Revel Energy. This offering represents a unique opportunity for investors seeking a secure, long-term investment with a single credit tenant. The building includes a cell tower and offers an attractive 7.38% going-in capitalization rate, which will rise to 8.00% following the installation of the solar PV system and annual rent escalations.
