Beautifully refreshed single-family home in a quiet Whittier neighborhood, featuring new interior and exterior paint, new and refinished flooring, and a clean move-in ready presentation. Situated on a generous 6,932 sq ft lot, this charming 1924 Spanish-style 2-bedroom, 1-bath home offers classic character, abundant natural light, and a functional layout ideal as a primary residence, rental, or front home for future development. What truly sets this property apart is its exceptional value-add potential. The oversized lot presents multiple opportunities for Accessory Dwelling Unit (ADU) development, including the possibility of a detached new-construction ADU and/or a Junior ADU (JADU), subject to city approval. Many buyers explore building an 800–1,200 sq ft ADU, creating multigenerational living, or generating additional rental income. A conceptual ADU rendering is available to help visualize the possibilities. Buyer to verify all ADU feasibility with the City of Whittier and check State Law. Additionally, this parcel may qualify for California SB 9, offering potential pathways for an urban lot split or additional residential units, subject to city approval. This flexibility makes the property especially attractive to investors, developers, buy-and-hold strategists, or owner-occupants looking to live in one unit while building long-term income. With its combination of location, lot size, architectural charm, and development potential, 13421 Sunset represents a compelling opportunity in today’s pro-housing market. Buyer to independently verify all square footage, zoning, and development possibilities with the appropriate city departments.

Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
