Are There Any New Home Developments or Master-Planned Communities Being Built in Santa Clarita in 2026?

Santa Clarita is one of the most active new-construction markets in Los Angeles County in 2026. The city has been on an intentional growth path for several years, and that trajectory has not slowed. According to a recent report on Santa Clarita's expansion plans, the city is moving forward with thousands of new residential units alongside parks, trails, and infrastructure improvements designed to support the growth.

How Active Is the Market?

As of September 2026, buyers in Santa Clarita can choose from new homes across multiple price points and community types, from attached townhomes starting in the mid-$500,000s to single-family detached homes in gated master-planned communities priced well above $1 million. Several large builders, including Lennar, Tri Pointe Homes, and William Lyon (now part of Taylor Morrison), have active phases open for sale in the Santa Clarita Valley right now.

Why Builders Are Still Building Here

Santa Clarita sits at a geographic and logistical crossroads that makes it attractive for large-scale residential development. The Interstate 5 and State Route 14 corridors connect the valley to employment centers in the San Fernando Valley, downtown Los Angeles, and the Antelope Valley. The city has invested heavily in road improvements, the Gold Line extension planning process, and water infrastructure, all of which give builders the confidence to commit to long-term master plans.

The broader national context matters here too. The National Association of Realtors has noted that 2026 presents a rare window for new-home buyers, as builders in suburban markets like Santa Clarita are offering meaningful incentives to move inventory while keeping base prices relatively stable. That dynamic is playing out locally in real time.

2. Active New Home Developments and Master-Planned Communities in 2026

Several distinct projects are actively selling or releasing new phases in the Santa Clarita Valley in 2026. Each has a different product mix, price point, and community character.

Valencia FivePoint: The Centerpiece Project

FivePoint Valencia is the largest master-planned community currently under development in Southern California, and it sits entirely within Santa Clarita's sphere of influence near the Newhall Ranch area. The full buildout calls for approximately 21,500 homes across multiple villages, along with retail, office space, schools, and parks woven throughout the plan. As of 2026, the first villages are well into their selling phases, with buyers able to tour model homes and purchase from several builders simultaneously.

The FivePoint project is notable for its sustainability commitments, including net-zero greenhouse gas emissions targets and a significant amount of dedicated open space and trail connectivity to the Santa Clara River area. Homes in the early villages have ranged from the high $600,000s for smaller attached plans to over $1.4 million for larger single-family detached homes on premium lots.

Castaic: The Fastest-Growing Pocket

Castaic, located at the northern end of the Santa Clarita Valley along Interstate 5, has seen a notable surge in new residential construction in 2026. Several smaller subdivisions and one larger community are currently under construction in this area. The appeal for buyers is that Castaic often offers lower base prices than Valencia or Stevenson Ranch, with new single-family homes available in the $550,000 to $850,000 range depending on size and lot position.

Castaic is also close to Castaic Lake, a 2,235-acre reservoir with boating, fishing, and swimming facilities. The combination of outdoor access and newer housing stock at relatively accessible price points has drawn consistent buyer interest throughout 2026.

Stevenson Ranch and Westridge Area

Stevenson Ranch, which sits just west of the main Valencia corridor near the Highway 126 interchange, has limited new construction compared to the FivePoint project, but there are infill phases and smaller communities releasing homes in 2026. The housing stock here skews toward larger single-family homes on wider lots, and the area is close to the Westfield Valencia Town Center and the network of hiking trails in the Santa Susana Mountains. For a deeper look at this part of the valley, the Stevenson Ranch real estate market guide covers pricing, lot sizes, and what to expect when buying there.

Newhall and Canyon Country Infill Projects

Newhall and Canyon Country are seeing a different kind of new construction: smaller infill projects rather than large master plans. These are typically developments of 20 to 80 homes built on previously underused parcels near existing neighborhoods. Prices in these communities tend to be lower than the master-planned projects, with some attached townhome products starting in the mid-to-high $500,000s. Canyon Country in particular has seen several small-lot single-family projects break ground in 2026, adding modern floor plans to a corridor that has historically been dominated by resale inventory from the 1980s and 1990s.

3. What Are New Homes Selling For in Santa Clarita in 2026?

New home prices in Santa Clarita in 2026 span a wide range depending on community, builder, product type, and lot position. Buyers should expect to pay a premium over comparable resale homes, though that gap has narrowed as builders have leaned into incentives.

Entry-Level and Move-Up Price Ranges

Attached townhomes and smaller detached homes: These start around $540,000 to $620,000 in Castaic and Canyon Country infill projects. Plans typically run 1,400 to 1,800 square feet with two to three bedrooms.

Mid-range single-family detached homes: These fall in the $700,000 to $950,000 range across most active communities. Floor plans in this tier run 2,000 to 2,800 square feet and are the most common product type in the FivePoint villages and Stevenson Ranch infill.

Premium and large-lot homes: These start around $1,050,000 and can exceed $1.5 million in the FivePoint master plan for homes with larger lots, view positions, or expanded square footage above 3,200 square feet.

How Builder Incentives Work Right Now

In September 2026, most active builders in Santa Clarita are offering some combination of mortgage rate buydowns, closing cost credits, and design center upgrades rather than reducing base prices. A rate buydown of one to two percentage points for the first few years of a loan can meaningfully reduce a buyer's monthly payment, which is why builders prefer this approach. It lets them maintain the listed price while making the purchase more affordable in the short term.

Design center credits are another common incentive. Builders may offer $25,000 to $60,000 in credits toward flooring, countertops, cabinetry, and fixtures. These credits must typically be spent within the builder's own design center, so it is worth understanding what options are available before assuming the credit covers everything you want.

4. Master-Planned Communities vs. Standard Subdivisions: What Is the Difference?

Not all new construction in Santa Clarita is the same. Understanding the difference between a master-planned community and a standard subdivision helps buyers set realistic expectations about what they are buying into.

What Master-Planned Means in Practice

A master-planned community is a large-scale development designed from the ground up with a cohesive vision for land use, amenities, and infrastructure. FivePoint Valencia is the clearest example in Santa Clarita right now. It includes dedicated commercial areas, parks, trail systems, school sites, and community facilities all built into the plan from the start. Residents in a master-planned community typically have access to shared amenities like pools, clubhouses, and maintained open space that are managed through the HOA.

A standard subdivision, by contrast, is a smaller development that may have its own HOA and shared amenities but does not have the same scale of integrated planning. The infill projects in Newhall and Canyon Country fall into this category. They offer new construction quality without the full master-plan ecosystem around them.

HOA Fees and Mello-Roos in New Santa Clarita Communities

Buyers in new Santa Clarita developments should budget carefully for ongoing costs beyond the mortgage. Most new communities carry HOA fees ranging from $150 to $450 per month depending on the level of amenities. Master-planned communities like FivePoint also layer in Community Facilities District (CFD) assessments, commonly called Mello-Roos, which are special tax bonds used to fund infrastructure like roads, utilities, and school facilities.

Mello-Roos assessments in the FivePoint area have ranged from approximately $3,000 to $7,000 per year depending on the home's assessed value and the specific CFD district. These are added to the base property tax rate and can significantly affect a buyer's total monthly housing cost. Always ask the builder's sales representative for the full CFD disclosure before making an offer, and review the property tax estimate with your real estate agent.

5. What Buyers Should Know Before Purchasing New Construction in Santa Clarita

Buying a new home in Santa Clarita in 2026 is meaningfully different from buying a resale property. The process, the contracts, and the negotiation dynamics all work differently, and buyers who go in without preparation often leave money on the table.

Builder Contracts Are Not Like Resale Contracts

Builder purchase agreements are written by the builder's legal team and strongly favor the builder. They typically include provisions that allow the builder to delay the closing date, substitute materials, and limit the buyer's ability to cancel without losing a deposit. Unlike a standard California Residential Purchase Agreement, a builder contract is not a neutral document. Buyers should read every page carefully and ideally have a real estate professional review it before signing.

Earnest money deposits on new construction in Santa Clarita typically run between 3% and 5% of the purchase price, and some builders require additional deposits at the design center stage. Understanding when those deposits become non-refundable is critical before you commit.

Getting Representation as a New-Home Buyer

The sales agent at a builder's model home works for the builder, not for you. Having your own real estate agent costs you nothing as a buyer in most new-construction transactions in California, because the builder pays the buyer's agent commission as part of the sale. Your agent can review the contract, negotiate incentives on your behalf, recommend an independent home inspector, and make sure the closing timeline works in your favor.

One important note: most builders require that your agent accompany you or register you on your first visit to the sales office. If you visit a model home without your agent present, the builder may refuse to pay the buyer's agent commission later, which can complicate your representation. Register your agent before your first visit to any new-home community in Santa Clarita.

If you are also selling a home to fund your new construction purchase, the Santa Clarita home selling guide walks through how to time both transactions and what to expect from the current resale market.

The new-construction landscape in Santa Clarita in 2026 offers genuine opportunities, but it rewards buyers who come prepared. Knowing which communities are actively selling, what the true all-in monthly cost looks like with HOA and Mello-Roos, and how builder contracts differ from resale agreements puts you in a much stronger position from day one.
