171 Costa Mesa Street A Welcome to this charming 1942 cottage with a custom-built "catio" and native plantings set in the heart of Eastside Costa Mesa. Offering approximately 900 sq ft, this two-bedroom, one-bath home blends vintage appeal with modern updates to create an inviting, livable retreat. Inside, original details set the tone — warm wood floors and elegant interior French doors open to the front bedroom, creating a flexible space ideal for guests, a home office, or creative use. The cozy, private rear bedroom offers generous closet space and is conveniently located near the full bathroom. In the kitchen, classic tilework and cabinetry bring personality and color, reinforcing the home’s connection to its era while still remaining functional for everyday use. Out front, a beautifully curated landscape of California native plants creates a welcoming, low-maintenance setting that feels environmentally mindful. A long driveway leads to a detached garage, providing roomy parking for one and additional storage space. Additional highlights include a separate inside laundry room, ductless heating and air conditioning for year-round comfort, side door for ease of entry from the driveway, and a "catio" that provides a safe and enriching outdoor space for feline companions. This unit is the front unit (of two), and does not include use of the backyard space. Water and twice-monthly gardening services included. Minutes from the Back Bay's trails and recreational activities, neighborhood boutiques, 17th Street, Triangle Square, and more.
