A rare find in the heart of Santa Ana: a legal triplex on an exceptional corner lot, just blocks from Downtown, offering strong income, this property consists of a charming early-1900s front house and a separate rear building, giving residents the privacy and feel of detached living rather than a shared-wall apartment layout. Originally a 2 bed 1 bath house SFR up front, over the years the property has been adapted from its original configuration to suit the way it’s lived in today; a second bathroom was added to the front house. And the rear building, originally two 1 bed 1 bath units, now being rented as a single 2 bed 2 bath residence with one kitchen. These modifications were made without permits; buyer to verify all square footage, unit count, permit status, and zoning with the Orange County assessors office & City of Santa Ana. The new home owner can leave as is or possibly restore these two residences to their orinal configuration. The large lot leaves room for future possibilities, and the central location puts tenants minutes from Downtown Santa Ana’s dining and arts district, transit, schools, and major freeways. This is a fantastic opportunity for any investor.
