Welcome to 238 E. Mendocino St., a rare and enchanting opportunity to own a piece of Altadena's storied past. Tucked behind the iconic Villa Carlotta estate, which still stands, this 9,900 sq ft lot once served as the site of the villa's original carriage house, evoking a dreamy historical elegance and timeless appeal. Accessed via a private, tree-lined motor court, the property provides exceptional privacy and serenity, surrounded by lush foliage and neighboring multi-million dollar estates, many of which are still intact. Whether you're looking to build your dream home or create a private retreat, the possibilities here are endless. With the added option to purchase the adjacent lot at 240 E. Mendocino, a truly expansive estate can be realized. Phase 2 environmental review has already been completed by the Army Corps of Engineers, paving the way for your vision to come to life. Previously, this lot was home to a charming 3-bed, 2-bath residence spanning 1,758 sq ft, showcasing the potential that awaits. Ideally located near Altadena's scenic hiking trails, parks, shops, and schools, this lot combines private, tranquil living with convenient access to all the community has to offer.

Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months.

Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
