12501 Philadelphia St 8,521 SF 100% Leased Office Building Whittier, CA 90601 $5,453,607 CAD ($640.02 CAD/SF) 5.47% Cap Rate

Powerhouse Commercial is pleased to present 12501 Philadelphia Street — a three-parcel, ±0.57-acre gateway redevelopment opportunity at the western edge of Uptown Whittier. The site is offered as a fully assembled package across three separate APNs (8139-010-016, 8139-010-027, 8139-010-031) under common ownership by Whittier Business Center LLC.
ZONING AND ENTITLEMENT
The parcels sit in the C-2-HO General Commercial with Housing Overlay zone, which permits vertical mixed-use development with ground-floor retail and residential above. Maximum residential density under the overlay is 25 du/ac with a 0.75 FAR and 40-foot height limit. Indicative scale: approximately 14 units by-right under C-2-HO base zoning, with the State Density Bonus pathway supporting up to approximately 20 units with ground-floor retail. AB 2011 streamlined ministerial approval may apply depending on Philadelphia Street right-of-way verification, and AB 1287 stacking is available for additional affordable units.
The City of Whittier's Envision Whittier 2040 General Plan, adopted October 2021, calls for higher-density mixed-use along this corridor. Implementing zoning amendments are currently in process. Buyers underwriting beyond the by-right scenarios should review the City's pending updates as part of their due diligence.
REDEVELOPMENT PRECEDENT
The site sits one block east of Comstock Place, a 24-townhome project approved by the City of Whittier in February 2025 at 29.27 du/ac. Directly across the street is Mosaic Gardens at Whittier — LINC Housing's 21-unit affordable LIHTC project at 45 du/ac. Olson Homes has separately received approvals on a townhome project nearby in the southeast submarket. These precedents demonstrate the City's active appetite for new corridor density and provide tangible reference points for buyer underwriting.
IN-PLACE INCOME
The site is improved with an ±8,521 SF multi-tenant executive suite building (1959, renovated 1971) currently generating approximately $300,000 in annualized scheduled gross rental income across approximately 30 active tenants. 2025 actual collections were $259,456 against $301,507 scheduled rent (86.1% collection rate). True operating expenses, excluding debt service, ran approximately $43,586 in 2025 — a 14.5% expense ratio against gross scheduled rent. 2025 actual NOI was $215,870, representing a 5.47% cap rate at the list price. Indicative scheduled NOI of $257,921 implies a 6.53% cap if collection stabilizes. A complete verified financial summary with month-by-month rent rolls, operating expense detail, and stabilized projections is available in the Due Diligence package on LOI execution.
The in-place income supports holding costs while a buyer pursues entitlement, offering meaningful downside protection on the redevelopment underwriting thesis.
PARKING ADVANTAGE
The site delivers 40 surface parking stalls, a 4.69 per 1,000 SF ratio — rare for the Uptown corridor. The parcels sit directly across Comstock Avenue from the City of Whittier's 351-space Uptown Public Parking Structure, providing material parking-reduction leverage for a future residential or mixed-use development program.
LOCATION
12501 Philadelphia Street is positioned at the corner of Philadelphia Street and Comstock Avenue, one block from the Greenleaf Avenue retail corridor that anchors Uptown Whittier — restaurants, cafes, and boutique retail. The Walk Score is 94, placing the site in the top decile of walkability nationally. Whittier College is 0.6 miles away with approximately 1,700 students. PIH Health Whittier Hospital, a major regional employer, is 1.1 miles away. I-605 freeway access is 2.4 miles, and Downtown Los Angeles is approximately 14 miles via the 605/5 corridor. The submarket has a 1-mile-radius population of approximately 32,800 with median household income of approximately $89,400.
