Tesoro del Valle & Tesoro Highlands Homes: Prices, HOA and Schools

Where is Tesoro del Valle?

Tesoro del Valle is a hillside master-planned community in the northwest Santa Clarita Valley, north of Copper Hill Drive around Tesoro Del Valle Road and Avenida Rancho Tesoro. Homes there are recorded under Valencia (ZIP 91354).

Tesoro was unincorporated Los Angeles County land until the City of Santa Clarita annexed it effective November 14, 2022, the City's 41st annexation (about 1,786 acres). At the time, the City counted 1,077 homes in the annexed area, 820 more in development, and more than 700 acres of permanently preserved open space with trails.

Tesoro Highlands is the newer master plan that Lennar describes as sitting above Tesoro del Valle in the hills. Tesoro Adobe Historic Park, at 29350 Avenida Tesoro, is a City-run historic site that was once the ranch of Western film actor Harry Carey Sr.

Who built Tesoro, and when?

The original Tesoro del Valle neighborhoods were developed by Montalvo Properties LLC, which the City names as the developer of the surrounding Tesoro community when Los Angeles County acquired the adobe property from it in 2005. The newer Tesoro Highlands phases are being built by Lennar and Toll Brothers, and both builders were still selling homes there in October 2026.

Tracts with "Tesoro" in their name that closed sales from October 2024 to September 2026:

One caveat matters a lot here. Every sale in these tracts was a home built from 2023 to 2026, so the figures on this page mostly describe new-construction Tesoro Highlands. Resales of the established Tesoro del Valle homes are usually filed under other tract names and don't show up when you match on "Tesoro." Treat the numbers below as a Tesoro Highlands snapshot, not a count of every home sold in the community.

How much do homes in Tesoro cost?

The median sale price in tracts named Tesoro was about $1,075,000 across 177 sales from October 2024 to September 2026. The middle 80% of sales ran from about $738,000 to $1.74 million.

The 30 condominium sales were mostly in the Sierra Bella tracts, which Lennar markets as single-family homes but which are recorded as condominiums. Medians shift with the mix of collections closing in a given month, so compare floor plans, not just medians.

What are HOA dues in Tesoro?

Every sale in these tracts had an HOA, and the median dues were $345 a month. Lennar's community data lists $338 a month for its larger single-family collections and $483 a month for the Sierra Bella 55+ collection, so dues depend on which neighborhood you buy in.

Lennar lists these Tesoro Highlands amenities: a pool, clubhouse, fitness center, parks, a dog park, tennis and pickleball courts, trails, BBQ and picnic areas, a community garden, and gated entry points. Some collection pages call the clubhouse, pool, playgrounds and trails "future-planned," so check what is finished before you close. The established Tesoro del Valle neighborhoods have their own association and amenities. Ask for the CC&Rs and the current budget for both the master and any sub-association.

Is any part of Tesoro age-restricted?

Yes. Lennar's Sierra Bella collection at Tesoro Highlands is a 55+ active-adult neighborhood, and 45% of the Tesoro sales carried a senior-community designation. Federal law lets housing that meets the Housing for Older Persons Act standards operate as 55+ housing. See Santa Clarita 55+ communities for other options.

Which schools serve Tesoro?

Tesoro del Valle Elementary (TK–6, 29171 Bernardo Way) is a Saugus Union School District school. In the William S. Hart Union High School District, Rio Norte Junior High students move on to Valencia High School, and most Tesoro listings report Valencia High School.

Lennar lists Tesoro Del Valle Elementary, Rio Norte Junior High and Valencia High for Tesoro Highlands. Boundaries can change, so confirm any address with the Saugus Union locator and the Hart district locator.

What should you check when buying in Tesoro?

• New phases are still selling. Builder inventory competes with resales. Compare a resale against current builder pricing and incentives at the same floor-plan size.
• HOA tiers. Dues differ by collection ($338 vs. $483 a month in Lennar's data). Confirm what the master association covers and what any sub-association adds.
• Special taxes. Lennar's data shows an estimated total tax rate of about 1.9% for its larger collections and 1.3% for Sierra Bella. Listing data doesn't show Mello-Roos, so read the Community Facilities District (CFD) disclosure, the preliminary title report and the Los Angeles County property tax bill for the actual special-tax lines.
• Age restriction. If a home is in Sierra Bella, read the age-verification and occupancy rules in the CC&Rs.
• Which Tesoro. Ask which tract and association a listing belongs to. Tract names don't always make the difference between the original community and Tesoro Highlands obvious.
