89 E. Orange Grove Avenue features a flat 20,923-square-foot lot with City-approved building plans for a 3-bedroom, 3-bathroom single-family residence offering approximately 2,093 square feet of living space, plus a 441-square-foot two-car garage. The generous lot size may also allow for the addition of an ADU, subject to buyer verification and City approval. The property was traditionally subdivided through the City of Sierra Madre, which may present an opportunity for a future owner to pursue an additional lot split under SB9, potentially allowing up to four units, subject to buyer due diligence and municipal approval. The sale includes fully approved architectural and building plans, allowing the buyer to move forward with construction if desired. The adjacent parcel is also available for purchase and includes its own approved plans (see Listing ID CV26000640).
