Simi Valley and Thousand Oaks are the two largest cities in east Ventura County and the two most common short-list options I see from buyers relocating into the area. They are about twenty minutes apart, share a regional job market, and look similar from a freeway exit -- but the underlying numbers are different. As of May 2026, the median sale price in Simi Valley is approximately $885,000 with a typical days-on-market around 18, while Thousand Oaks sits closer to $1.15 million. The school districts, lot sizes, commute directions and weather patterns also pull in different directions. This guide walks through each factor with the data, then frames it as scenarios rather than recommendations.
The headline difference
The single biggest gap between Simi Valley and Thousand Oaks is price. As of May 2026 the median sale price in Simi Valley is approximately $885,000, while Thousand Oaks is approximately $1.15 million. That is roughly a $265,000 spread at the midpoint, or about 30 percent. The gap is not uniform across the market -- entry-level Simi Valley condos under $600,000 have no real Thousand Oaks equivalent, and Westlake-adjacent homes in Thousand Oaks routinely clear $2 million.
Everything else -- schools, commute, weather, lots -- matters, but the price difference is what most buyers feel first. A buyer with a $1 million budget can shop the top quartile in Simi Valley or the bottom quartile in Thousand Oaks. That single fact reshapes which neighborhoods, square footages and lot sizes are actually on the table.
Price comparison
Here is how the two cities sort out by price bracket as of May 2026. Medians are approximate and drawn from California Association of REALTORS regional data plus MLS pulls. Treat them as starting points, not appraisals.
| Bracket | Simi Valley median | Thousand Oaks median | Difference |
|---|---|---|---|
| Condo / townhome | ~$560,000 | ~$680,000 | +$120,000 |
| Entry SFR (1,400-1,800 sf) | ~$850,000 | ~$960,000 | +$110,000 |
| Mid SFR (1,800-2,400 sf) | ~$885,000 | ~$1,150,000 | +$265,000 |
| Move-up SFR (2,400-3,200 sf) | ~$1,150,000 | ~$1,450,000 | +$300,000 |
| Luxury (3,200+ sf) | ~$1,500,000+ | ~$2,100,000+ | +$600,000+ |
Commute comparison
Both cities are served by the 118 (Simi) and 101 (Thousand Oaks) freeways, with SR-23 connecting the two. Drive times below are typical off-peak; add 20 to 60 percent in rush hour depending on direction.
| Destination | From Simi Valley | From Thousand Oaks |
|---|---|---|
| Warner Center / Woodland Hills | ~25 min | ~25 min |
| Burbank / Glendale | ~35 min | ~45 min |
| Downtown Los Angeles | ~50 min | ~55 min |
| Camarillo | ~25 min | ~20 min |
| LAX | ~55 min | ~50 min |
| Malibu / PCH | ~40 min | ~30 min |
| Ventura beaches | ~40 min | ~30 min |
Schools comparison (by district boundary)
Simi Valley homes are served by Simi Valley Unified School District (SVUSD). Thousand Oaks homes are served primarily by Conejo Valley Unified School District (CVUSD), with a small portion in the far east in Las Virgenes Unified. Both districts publish performance data on the California School Dashboard, which is the authoritative state source for accountability metrics.
I do not rank schools or imply who attends them. I point clients to the Dashboard for the colored indicator data (English language arts, math, graduation, suspension rate, chronic absenteeism) and to each district's published boundary maps for attendance area. Both are free public data.
Boundary verification matters because districts can and do redraw lines. Two homes one block apart can feed different schools, and an address you assume is in one boundary may sit just outside it. Always confirm the assignment for the specific address before writing an offer.
| Factor | Simi Valley (SVUSD) | Thousand Oaks (CVUSD) |
|---|---|---|
| Authoritative ratings source | CA School Dashboard | CA School Dashboard |
| Boundary map | simivalleyusd.org | conejousd.org |
| Approx K-12 enrollment | ~17,500 | ~17,000 |
| High schools (comprehensive) | 3 (Simi, Royal, Santa Susana) | 4 (Thousand Oaks, Westlake, Newbury Park, Conejo Valley) |
Lot size and inventory
Simi Valley's older tracts (built in the 1960s through 1980s) often deliver 7,000 to 10,000 square foot lots with single-story floor plans, particularly in neighborhoods such as Texas Tract, Knolls and parts of Madera. Thousand Oaks's older tracts tend to be comparable in size, but its newer master-planned areas (Lang Ranch, Dos Vientos) lean smaller due to infill density patterns of the 1990s and 2000s.
Newer Simi Valley master-plans (Wood Ranch, Big Sky, parts of Long Canyon) push lots back up into the 6,000 to 12,000 square foot range, with a small number of estate lots well above that. Thousand Oaks has its own estate pockets in North Ranch and Sherwood Country Club, but those typically clear $3 million.
| Inventory factor | Simi Valley | Thousand Oaks |
|---|---|---|
| Typical lot, older tracts | 7,000-10,000 sf | 6,500-9,500 sf |
| Typical lot, newer master-plans | 6,000-12,000 sf | 5,500-9,000 sf |
| DOM (median, May 2026) | ~18 days | ~22 days |
| Months of supply | ~2.1 | ~2.4 |
Property taxes and Mello-Roos exposure
Both cities sit under California Proposition 13, so the base ad valorem rate is 1 percent of assessed value, plus voter-approved local additions and any special assessments. The effective rate I generally tell clients to plan for is around 1.1 to 1.25 percent in older tracts.
Mello-Roos (Community Facilities District, or CFD) exposure is the meaningful difference. Older Simi Valley and Thousand Oaks tracts (pre-1990) generally have no Mello-Roos. Newer master-plans in both cities may carry CFDs that add roughly $1,500 to $4,500 per year. In Simi Valley this affects parts of Wood Ranch, Big Sky and Long Canyon. In Thousand Oaks it affects parts of Dos Vientos and Lang Ranch. The Ventura County Assessor publishes the parcel-specific tax bill and any CFD line items.
HOA prevalence and ranges
HOA exposure tracks the age and type of construction. Older detached tracts in both cities are typically HOA-free. Condos, townhomes and most newer master-planned single-family neighborhoods carry HOAs.
In Simi Valley, HOA dues commonly run $80 to $300 per month for detached homes in master-plans, $300 to $550 for typical condos and townhomes. In Thousand Oaks, the comparable detached HOA ranges are similar; Westlake-side condos and gated communities can run higher, $500 to $900 per month is not unusual.
Walk Score and lifestyle anchors
Both cities are car-oriented suburban communities with low Walk Scores by national standards. Lifestyle anchors differ.
Simi Valley landmarks include the Ronald Reagan Presidential Library and Museum, Simi Valley Town Center, Simi Valley Hospital (Adventist Health), the Simi Valley Library and the Rancho Simi Recreation and Park District system (50+ parks plus the Arroyo Simi greenway). Trail heads at Corriganville Park, Rocky Peak and Sage Ranch are popular.
Thousand Oaks landmarks include the Thousand Oaks Civic Arts Plaza (Bank of America Performing Arts Center), The Oaks shopping center, Los Robles Regional Medical Center, the Thousand Oaks and Newbury Park libraries, and the Conejo Open Space Conservation Agency trail system (Wildwood Park, Conejo Canyons, Los Robles Trail).
Weather and microclimate
Both cities are Mediterranean climate, but the Conejo Valley elevation (Thousand Oaks sits at roughly 800-1,100 feet) runs a few degrees cooler in summer and a few degrees cooler at night than the Simi Valley basin (roughly 700-900 feet). Marine layer reaches Thousand Oaks more reliably; Simi tends to clear earlier in the day and run a few degrees warmer on summer afternoons.
Rainfall is comparable -- both cities average around 15 to 18 inches per year in normal years. Wind events (Santa Ana conditions) affect both, with the north side of Simi Valley and the canyon edges of Thousand Oaks more exposed.
Which is the better fit for common buyer scenarios
Reframing the comparison as scenarios is more useful than picking a winner. These are amenity-based, not demographic.
The 101-corridor commuter. If your job is in Westlake Village, Agoura, Calabasas or the western 101 office parks, Thousand Oaks shaves drive time and the 23-to-101 interchange is the chokepoint you'll feel daily from Simi.
The 118-corridor or San Fernando Valley commuter. If your job is in Chatsworth, Northridge, Burbank or Glendale, Simi Valley is almost always the faster drive. The 118 connects directly into the north Valley.
The downsizer prioritizing single-story. Simi Valley's older tracts have more single-story inventory under $900,000 than Thousand Oaks does.
The buyer prioritizing yard space at a given budget. At budgets between $850,000 and $1.2 million, Simi Valley typically delivers more lot and more square footage per dollar.
The buyer prioritizing coastal access. Thousand Oaks is 10 to 15 minutes closer to PCH and Malibu via Westlake Boulevard or Las Virgenes.
The buyer needing specific school boundary. This is parcel-specific. Verify the address-level assignment for any home before you fall in love with it -- in either city.
The retiree on a fixed budget. Lower median price, comparable healthcare access (Simi Valley Hospital, Los Robles in Thousand Oaks) and comparable park access generally make Simi the more budget-friendly option.
Carrying cost worked example side by side
Comparing medians is useful, but the dollar gap that actually shows up in your monthly statement is what most buyers feel. Here is a worked carrying-cost comparison on the two median homes, both at 20 percent down and 6.75 percent on a 30-year fixed.
Simi Valley median, $885,000: down payment $177,000, loan $708,000, monthly P&I approximately $4,595. Property tax at 1.15 percent: $848/month. Insurance: ~$200/month. HOA on a non-HOA older tract: $0. Maintenance reserve at 1 percent: ~$738/month. Total monthly carry: approximately $6,381.
Thousand Oaks median, $1,150,000: down payment $230,000, loan $920,000, monthly P&I approximately $5,966. Property tax at 1.15 percent: $1,102/month. Insurance: ~$240/month. HOA on a typical non-master-plan home: $0. Maintenance reserve: ~$958/month. Total monthly carry: approximately $8,266.
Difference: roughly $1,885/month, or $22,620 per year. Over 10 years (before any rate or assessment changes), that gap accumulates to approximately $226,000. That is real money, and it shows up in every monthly bill. The $265,000 median-price gap is not abstract -- it shows up as roughly $2,000 more out the door each month.
Now layer in down payment opportunity cost: an extra $53,000 down at Thousand Oaks median, compounded at even 5 percent annually, grows to approximately $86,300 over 10 years. The all-in 10-year cost difference between buying the Simi median and buying the Thousand Oaks median, on these assumptions, is well over $300,000. Whether that gap is worth it depends entirely on what you get for it -- school boundary, commute, amenities, lifestyle fit. The point of the math is not to argue for either city; it is to make the trade-off concrete rather than abstract.
What I tell clients deciding between the two
Three questions usually settle it. First, where is the primary commute heading -- west toward Westlake/Malibu, or east into the San Fernando Valley? Second, what is the upper end of your budget, and how much house do you need at that budget? Third, is there a specific school boundary you need to be inside?
Once those are answered honestly, the choice usually narrows itself. If both cities are still viable, I tell clients to spend a Saturday in each. Drive the neighborhoods, sit in the coffee shops, visit the parks. The feel of a place is the part the spreadsheet can't tell you. Everything else -- price, taxes, schools, commute -- I can put in a comparison sheet for the specific address you are weighing.
Frequently Asked Questions
Is Thousand Oaks always more expensive than Simi Valley?
At the median, yes -- approximately $265,000 more as of May 2026. But the markets overlap. A Thousand Oaks condo in the $600,000s exists, and a Simi Valley estate home above $2 million exists. The medians describe the middle of each city, not the full range. Within a given price band, both cities can produce viable options. Pull a comparable-bracket search side by side and you will usually find Simi delivers more square footage and lot per dollar, while Thousand Oaks delivers proximity to the 101 corridor and Westlake-area amenities.
Which has a lower property tax bill?
Base rates are identical under Proposition 13 -- 1 percent of assessed value plus voter-approved additions. The effective rate in both cities typically lands between 1.1 and 1.25 percent in older tracts without Mello-Roos. Because Thousand Oaks median assessed values are higher, the dollar tax bill on the median home is higher there. Newer master-plan neighborhoods in either city may add Mello-Roos of $1,500 to $4,500 per year. Always pull the parcel-specific bill from the Ventura County Assessor before assuming.
Are the school districts comparable?
Both SVUSD and CVUSD publish performance data on the California School Dashboard, the state's official accountability source. Both are unified K-12 districts of similar enrollment (~17,000-17,500). Specific schools within each district perform differently -- so the address-level question is which campus a given home feeds, not which district name appears on the deed. I do not rank schools or suggest who attends them. I send clients to the Dashboard and to the district's own boundary map.
Which city has a shorter LA commute?
It depends on which part of LA. Simi Valley is faster to the San Fernando Valley, Burbank, Glendale and downtown via the 118 and 5. Thousand Oaks is faster to the Westside, LAX and Malibu via the 101 and Las Virgenes/Kanan. For Warner Center the two are roughly tied. Test your specific commute at the actual times you drive it -- Google Maps with the right departure time is more accurate than any generic chart.
Should I rent in one before buying in the other?
If you have not lived in Ventura County before, renting for six to twelve months in your top-choice city is rarely a bad idea. You learn the freeways at real-world times, you find out whether the marine layer reaches your block, and you stop being a tourist about the trade-offs. The cost is a rent payment that builds no equity and one extra move. The benefit is making a $900,000-plus decision with first-hand data.
Which city has more single-story homes?
Simi Valley generally has more single-story inventory in the under-$900,000 band, because more of its older tracts were built as single-story ranch designs. Thousand Oaks has single-story homes too, but its mid-priced inventory leans more two-story. If single-story is a hard requirement, filter for it in the MLS and you will see the count differential plainly.
Do both cities have Mello-Roos?
Both can. Mello-Roos (Community Facilities Districts) typically attach to newer master-planned neighborhoods. In Simi Valley that means parts of Wood Ranch, Big Sky and Long Canyon. In Thousand Oaks that means parts of Dos Vientos and Lang Ranch. Older tracts in either city typically have no Mello-Roos. The parcel-specific tax bill on the Ventura County Assessor site is the only authoritative answer for any given address.
Which has better weather?
Better is subjective. Thousand Oaks runs a few degrees cooler in summer and gets more marine influence. Simi Valley runs a few degrees warmer in summer and clears the marine layer earlier. Both are Mediterranean climate. If you dislike heat above 90 degrees, Thousand Oaks has fewer such days. If you prefer reliable sun, Simi has more of it.
Are HOA dues higher in one city?
It depends on the property type, not the city name. Older detached tracts in both cities are typically HOA-free. Condos and townhomes typically run $300-$550 per month in both. Newer master-plan detached HOAs run $80-$300 per month in both. Westlake-adjacent gated communities in Thousand Oaks can run notably higher ($500-$900). Always pull the CC&Rs and current dues for the specific HOA.
