Simi Valley and Santa Clarita are the two large suburban cities at the northwestern edge of the LA metro. They sit in different counties (Ventura and LA), are served by different school districts, and reach different destinations on different freeways. As of May 2026, the Simi Valley median sale price is approximately $885,000. Santa Clarita sits at approximately $925,000. Both are master-planned-heavy compared to older parts of the LA metro, both have strong park systems, and both feel suburban. The differences are in commute orientation, school district structure, master-plan density and feel.
The headline difference
Simi Valley and Santa Clarita are similar in scale (Simi ~125,000 people, Santa Clarita ~230,000 in the broader city limits including Valencia, Saugus, Newhall, Canyon Country) and similar in feel -- both are heavily master-planned suburban cities with strong park systems and good freeway access. The big differences are commute orientation and school district structure.
Santa Clarita sits along the I-5 corridor and is closer to north LA County, the Palmdale/Lancaster exit, and the entertainment-industry job centers in Burbank. Simi sits along the 118 and is closer to the west San Fernando Valley and the 101 corridor. The 40-minute drive between them goes through Newhall Pass and is sensitive to traffic in either direction.
Price comparison
Price brackets as of May 2026. Santa Clarita's master-plan-heavy inventory pushes the medians slightly above Simi's at most price points.
| Bracket | Simi Valley median | Santa Clarita median | Difference |
|---|---|---|---|
| Condo / townhome | ~$560,000 | ~$600,000 | +$40,000 |
| Entry SFR (1,400-1,800 sf) | ~$780,000 | ~$820,000 | +$40,000 |
| Mid SFR (1,800-2,400 sf) | ~$885,000 | ~$925,000 | +$40,000 |
| Move-up SFR (2,400-3,200 sf) | ~$1,150,000 | ~$1,200,000 | +$50,000 |
| Luxury (3,200+ sf) | ~$1,500,000+ | ~$1,700,000+ | +$200,000+ |
Commute comparison
Santa Clarita sits on I-5; Simi sits on the 118. Drive times below are off-peak; rush hour through the Newhall Pass or the Conejo Pass can add 30-60 percent.
| Destination | From Simi Valley | From Santa Clarita |
|---|---|---|
| Burbank / Glendale | ~35 min | ~25 min |
| Downtown Los Angeles | ~50 min | ~35 min |
| Pasadena | ~50 min | ~40 min |
| Warner Center / Woodland Hills | ~25 min | ~30 min |
| Chatsworth / Northridge | ~20 min | ~25 min |
| Thousand Oaks | ~20 min | ~40 min |
| Palmdale / AV | ~80 min | ~45 min |
| LAX | ~55 min | ~50 min |
Schools comparison (by district boundary)
Simi Valley homes are served by Simi Valley Unified (SVUSD) -- one unified K-12 district. Santa Clarita's school district structure is more complex. Elementary and middle school assignment depends on the specific area of the city: Newhall School District serves the Newhall area; Saugus Union serves Saugus and Valencia; Sulphur Springs serves Canyon Country; and Castaic Union serves Castaic. All four feed into William S. Hart Union High School District (WSHUHSD) for grades 9-12.
The California School Dashboard publishes performance data for every campus in SVUSD, the four Santa Clarita K-8 districts, and WSHUHSD. For Santa Clarita addresses, boundary verification means checking two district maps (K-8 and HS) rather than one. Always verify the parcel-level assignment before writing an offer.
| Factor | Simi Valley (SVUSD) | Santa Clarita |
|---|---|---|
| Authoritative ratings source | CA School Dashboard | CA School Dashboard |
| K-8 district | SVUSD (unified) | 4 districts (Newhall, Saugus, Sulphur Springs, Castaic Union) |
| High school district | SVUSD (unified) | William S. Hart Union HSD |
| Comprehensive high schools | 3 (Simi, Royal, Santa Susana) | 6+ (Valencia, Saugus, Canyon, Hart, West Ranch, Golden Valley, Castaic) |
Master-plan density and feel
Santa Clarita's housing stock is heavily master-planned -- Valencia (multiple villages), Stevenson Ranch (in unincorporated LA County adjacent), the newer Tesoro and Plum Canyon areas, Five Knolls and Skyline are all planned communities with HOAs. Master-plan share is high, probably 60-70 percent of inventory.
Simi Valley's master-plan share is lower, probably 20-25 percent. The bulk of Simi housing stock is older non-HOA tracts from the 1960s-1980s. If you specifically want a master-plan feel with HOA-managed amenities (community pools, paseos, gated parks), Santa Clarita has more options. If you want older non-HOA tracts with mature trees, Simi has more.
| Inventory factor | Simi Valley | Santa Clarita |
|---|---|---|
| Master-plan share (est.) | ~20-25% | ~60-70% |
| Typical lot, older tracts | 7,000-10,000 sf | 6,500-9,000 sf |
| Typical lot, newer master-plans | 6,000-12,000 sf | 4,500-7,500 sf |
| DOM (median, May 2026) | ~18 days | ~22 days |
Property taxes and Mello-Roos exposure
Both are under Proposition 13 -- base 1 percent of assessed value plus voter additions. The important difference: Santa Clarita's master-plan share means much more inventory carries Mello-Roos than in Simi.
Newer Santa Clarita developments (Plum Canyon, Tesoro, Five Knolls, Skyline, parts of Stevenson Ranch and West Hills) commonly carry CFD assessments of $2,500-$6,000+ per year. Simi Valley Mello-Roos concentrates in Wood Ranch, Big Sky and Long Canyon at $1,500-$4,500/year. Older tracts in both cities typically have no CFDs. The LA County Assessor (Santa Clarita) and Ventura County Assessor (Simi) publish parcel-specific line items.
HOA prevalence and ranges
Santa Clarita HOAs are common given the master-plan-heavy inventory. Detached single-family HOAs in newer Santa Clarita communities typically run $120-$350/month. Condos and townhomes run $350-$650/month. Gated communities can run higher.
Simi Valley HOAs are less prevalent overall because more inventory is in older non-HOA tracts. Where they exist, master-plan detached HOAs run $80-$300/month and condos run $300-$550.
Weather and microclimate
Both cities run hot in summer. Santa Clarita sits at slightly higher elevation (~1,200-1,500 feet across the valley) and runs comparable temperatures to Simi but with less marine influence reaching the eastern parts (Canyon Country). Heat waves of 95-105 degrees are normal in both. Simi gets modest marine influence late in the day; Santa Clarita generally does not.
Santa Ana wind events affect both. Brush-fire exposure is significant in both -- the wildland-urban interface around Castaic, Canyon Country and the canyons of Simi all have CAL FIRE Fire Hazard Severity Zone designations. Insurance implications are real in both cities.
Walk Score and lifestyle anchors
Both are car-oriented. Anchors differ in scale.
Santa Clarita includes Six Flags Magic Mountain and Hurricane Harbor (Valencia), the Westfield Valencia Town Center, Valencia Marketplace, Henry Mayo Newhall Hospital, College of the Canyons (community college), CSU Channel Islands (within driving distance) and an extensive paseo trail network through Valencia. The Santa Clarita Community Hiking Trail and the Vasquez Rocks Natural Area Park are within reach.
Simi Valley includes the Ronald Reagan Presidential Library and Museum, Simi Valley Town Center, Simi Valley Hospital (Adventist Health), the Simi Valley Library and 50+ parks via Rancho Simi Recreation. Corriganville and Rocky Peak are popular trailheads.
Which is the better fit for common buyer scenarios
Amenity-based, not demographic.
The Burbank / entertainment-industry commuter. Santa Clarita is 10-15 minutes closer to Burbank studios.
The 101 / west Valley commuter. Simi has the shorter drive.
The buyer who wants master-plan amenities. Santa Clarita's Valencia villages and newer communities offer more master-plan inventory.
The buyer who wants older non-HOA tracts. Simi has more.
The buyer at the same budget who wants more lot. Roughly tied, with Simi slightly edging on lot size in older tracts.
The buyer with kids in specific schools. Both districts publish Dashboard data. Santa Clarita's structure (four K-8 districts plus WSHUHSD) means more boundary moving parts. Address-level verification is essential in both.
The buyer who wants a Ventura County address. Simi is the only choice here -- Santa Clarita is in LA County.
School district complexity: a closer look
Santa Clarita's school district structure deserves more attention than a single-district comparison usually gets. The city straddles four elementary/middle districts plus one shared high school district. For buyers with school-age kids, that complexity matters.
Newhall School District (NSD) serves the central and older parts of Santa Clarita, including much of Newhall and parts of Valencia. K-6 typically.
Saugus Union School District (SUSD) serves Saugus and much of newer Valencia. K-6.
Sulphur Springs Union School District (SSUSD) serves Canyon Country. K-6.
Castaic Union School District (CUSD) serves the Castaic area. K-8.
William S. Hart Union High School District (WSHUHSD) handles grades 7-12 (or 9-12 depending on feeder pattern) across the entire city. Comprehensive high schools include Valencia, Saugus, Canyon, Hart, West Ranch, Golden Valley, Castaic and others.
Practical implication: when you tour a Santa Clarita address, you are evaluating TWO districts' performance data (the K-8 district plus WSHUHSD), not one. Plus the specific assigned campuses within each. The California School Dashboard makes the data available; the work is matching addresses to the right campuses.
Simi Valley's SVUSD is simpler -- one district, three comprehensive high schools, defined boundary maps. Address-level verification still matters (boundary lines do shift), but you are checking one district's map rather than two.
Neither structure is better in absolute terms. Multi-district structure can provide more variety and magnet options; unified structure provides simpler navigation. What matters is the campus that serves the specific address you are considering. The California School Dashboard is the authoritative state data source for both. Always pull the data for the actual assigned campuses, not the district average.
Carrying cost and inventory rhythm comparison
The price gap between Simi and Santa Clarita is small (~5 percent at the median), but carrying cost and inventory rhythm differ in ways worth understanding.
Carrying cost on the median home. Comparing the Simi median ($885,000) to the Santa Clarita median ($925,000), both at 20 percent down and 6.75 percent on a 30-year fixed, the monthly P&I difference is small (~$210). Property tax difference on the higher Santa Clarita assessed value adds another ~$40/month at 1.15 percent.
The meaningful divergence is in Mello-Roos and HOA. Santa Clarita's master-plan share is much higher -- 60-70 percent of inventory versus 20-25 percent in Simi. So at random, a Santa Clarita purchase is much more likely to include CFD and HOA assessments. Add $300/month Mello-Roos and $200/month HOA on a typical newer Santa Clarita master-plan home, and the carrying cost difference vs. a no-CFD no-HOA older Simi tract grows to ~$750/month, or ~$9,000/year. Over 10 years, ~$90,000 in additional carrying cost.
Inventory rhythm. Santa Clarita's larger population and broader geography produce more monthly inventory turnover -- typically 400-600 active MLS listings citywide in a normal month. Simi runs 250-350. Both markets have similar DOM in May 2026 (Simi ~18 days, Santa Clarita ~22 days).
Newer construction availability. Santa Clarita has consistently more new-construction and recent-build inventory because it has continued to develop over the past decade. Plum Canyon, Tesoro, Five Knolls, Skyline and other newer phases produce regular new-build and lightly-used resale inventory. Simi's new build is mostly limited to later phases of Big Sky and occasional infill.
School district turnover. Santa Clarita's school district structure (four K-8 plus one HS district) means more parents are watching for specific feeder patterns. Homes in high-demand elementary boundaries see faster sales. Same applies in Simi (SVUSD elementary boundaries vary in market appeal), but the multi-district complexity in Santa Clarita produces more nuanced boundary-driven pricing.
Bottom line for buyers. If new construction or master-plan inventory is essential, Santa Clarita has more to choose from at any given moment. If you want older non-HOA tracts at lower carrying cost, Simi has more options. The cities are more alike than different on the high-level metrics; the differences show up at the inventory level.
What I tell clients deciding between the two
These cities are similar enough that the right answer often comes down to commute and school preference rather than city character. I tell clients to test the actual drive at the actual times they'd commute, in both directions. Simi-to-Burbank at 7:30 AM is materially different from Simi-to-Burbank at 10 AM.
On schools, both districts publish Dashboard data. The structural difference (Simi's one unified district vs Santa Clarita's four K-8 districts plus WSHUHSD) means boundary verification in Santa Clarita takes a bit more work. Same approach either way -- verify the specific campus assignment for the specific address before writing an offer. Beyond that, spend a Saturday in each city. Walk Valencia Town Center, walk Simi Valley Town Center, sit in a park in each. The numbers I can put in a side-by-side.
Frequently Asked Questions
Is Santa Clarita more expensive than Simi Valley?
Slightly, yes. As of May 2026, Santa Clarita median sits at approximately $925,000 vs approximately $885,000 in Simi -- about a $40,000 spread, or roughly 5 percent. The gap is consistent across most price bands. Santa Clarita's larger master-plan share, newer construction and slightly higher carrying-cost structure (more HOA, more Mello-Roos) drive part of the difference.
Which has a shorter commute to Burbank or LA?
Santa Clarita, typically by 10-15 minutes to Burbank and downtown LA via I-5. Simi adds a Newhall Pass crossing if you are going the same direction. For Burbank studios specifically, Santa Clarita is the shorter drive almost every time. For the west San Fernando Valley or the 101 corridor, Simi wins.
Are the school districts comparable?
Both are reflected on the California School Dashboard, the state's authoritative accountability source. Structurally they differ: Simi is one unified K-12 district (SVUSD). Santa Clarita has four K-8 districts (Newhall, Saugus, Sulphur Springs, Castaic Union) plus William S. Hart Union HSD for high school. For Santa Clarita addresses you are checking two district boundary maps per address. Address-level verification is essential in both cities.
Which has more Mello-Roos?
Santa Clarita, on average. Its master-plan share is higher -- Plum Canyon, Tesoro, Five Knolls, Skyline, parts of Stevenson Ranch and others carry CFD assessments of $2,500-$6,000+/year. Simi's Mello-Roos concentrates in Wood Ranch, Big Sky and Long Canyon at $1,500-$4,500/year. Older tracts in either city typically have none. The LA County Assessor (Santa Clarita) and Ventura County Assessor (Simi) publish parcel-specific line items.
Does Santa Clarita have hotter summers?
Comparable. Both cities run hot in summer with regular 95-105 degree heat waves. Santa Clarita's eastern neighborhoods (Canyon Country) get less marine influence and can run a few degrees hotter than Simi at peak. Simi gets modest late-day marine layer in summer; Santa Clarita generally does not. Neither is a 'cool summer' choice; for that, look toward Camarillo or coastal Ventura County.
Should I choose Simi or Santa Clarita for amusement parks?
Santa Clarita has Six Flags Magic Mountain and Hurricane Harbor within city limits in Valencia. Simi Valley does not. If amusement parks are a regular weekend activity, Santa Clarita has the proximity advantage. Both cities are roughly equidistant from Disneyland (about 90 minutes via the right freeways).
Are HOA dues higher in Santa Clarita?
On average, yes, because Santa Clarita's master-plan share is higher and more inventory carries HOAs at any given time. Detached HOAs in newer Santa Clarita communities run $120-$350/month; Simi's master-plan detached HOAs run $80-$300/month. Older Simi tracts are more often HOA-free. Always pull the specific HOA's CC&Rs and current dues for the property you are considering.
Which is closer to the Antelope Valley?
Santa Clarita, by a wide margin. The drive from Santa Clarita to Palmdale or Lancaster is roughly 45 minutes via the 14. From Simi the same trip is roughly 80 minutes. If you have family or work tied to the Antelope Valley, Santa Clarita's geography matters.
