Altadena, CA

Talk about having the odds stacked against you: Altadena was founded on land that nobody wanted. Shaved off of a 14,000-acre Mexican land grant (the lion’s share went to the formation of Pasadena and South Pasadena), the land was considered too hard to reach – and too close to the mountains – to cultivate citrus crops.

But this unincorporated community of roughly 42,000 today has managed to thrive anyways in the shadow of Mount Wilson, one of the San Gabriel Mountain’s most well-known peaks and home to a famous observatory.

Altadena takes its name from a former business in the foothills there, the Altadena Nursery. The owner coined the term by joining the Spanish word “alta” for upper with “dena” as in Pasadena to the south: The two cities share a border, a school district and other cultural resources.

Ethnic representation in the city changed a great deal, especially during the 1960s (you can get an idea about the city’s demographics by looking at www.city-data.com); and vestiges of the past remain in the old mansions you’ll see on Mariposa Street near Santa Rosa Avenue—a location that became known as “Millionaire's Row” when various tycoons from the East settled there in the late 1800s and early 1900s.

Santa Rosa Avenue is also the place of another popular event: Pasadena might lay claim to the Tournament of Roses Parade, but Altadena has “Christmas Tree Lane”—one of the oldest, large-scale outdoor Christmas tree lighting events in the U.S.

What was long ago considered a problem for citrus growers—that Altadena was too close to the mountains—is now an advantage.

Today lovers of the outdoors will find plenty to do in Altadena, including hiking trails in Las Flores Canyon to the north and a botanical garden open to the public. The Sam Merrill Trail, which starts just north of Altadena, takes hikers up to the ruins of the historic Mount Lower Railway, which once shuttled passengers to several resorts built in the foothills.

That trail not only provides hikers with a good workout: It acts like a time machine, giving them a glimpse into the area’s not-so-distant past.

RARE ALTADENA VIEW LOT — ±0.53 ACRE | NEAR-RTI PLANS | EXCEPTIONAL PRIVACY Not all land opportunities are created equal. This extraordinary Altadena property offers a combination that is increasingly difficult to find: over half an acre of land, a private end-of-street setting, sweeping unobstructed mountain views, and professionally designed plans already nearing RTI status. Situated on an expansive ±0.53-acre lot (approximately 23,087 sq. ft.), this property was impacted by the 2025 Altadena Fire and now presents an exceptional opportunity to create a brand-new custom residence in one of Altadena’s most desirable natural settings. What truly separates this property from other available lots is its location and privacy. Tucked away at the end of the street and approached by a long shared driveway, the homesite feels removed from the surrounding neighborhood while still being conveniently located. Its elevated position captures dramatic, unobstructed panoramic mountain views, creating a spectacular backdrop for a future residence. Another major advantage: much of the difficult planning work has already been done. Included in the sale are professionally designed architectural plans for an approximately 3,200 sq. ft. two-story residence with a 2-car garage. The plans have already been submitted and are nearing Ready-to-Issue (RTI) status, potentially saving the next owner considerable time, planning, and expense compared with starting a new project from scratch. The surrounding neighborhood is already moving forward, with multiple homes under construction and a new chapter of Altadena taking shape. For those drawn to the Altadena lifestyle, the location is difficult to duplicate—close to hiking, nature, mountain recreation, and equestrian facilities, while offering the space and serenity to create a true private retreat. What makes this property stand apart: • ±0.53 acre / approximately 23,087 sq. ft. lot • Rare end-of-street location • Elevated setting with unobstructed panoramic mountain views • Professionally designed ±3,200 sq. ft. home plans included • Plans already submitted and nearing RTI status • Nearby homes already rebuilding and under construction • Close proximity to hiking trails and equestrian amenities • Opportunity to build new without starting the planning process from zero A truly special opportunity for an owner-user, builder, or developer looking to create a one-of-a-kind Altadena estate.
