There's a rectangle in the West Valley about 1.5 miles long and a mile wide. Roscoe to the north, Saticoy to the south, Balboa to the east, and Lindley to the west. Three ZIP codes meet inside it: 91325 Northridge, 91406 Lake Balboa, and 91335 Reseda.
Buyers ask me almost every week which side they should land on. After 15+ years working in the San Fernando Valley, my honest read is that this is the most underwritten seam in the West Valley. I live inside this rectangle myself. I started in a smaller home in Lake Balboa, moved up to Northridge, and then chose to come back to Lake Balboa for my current home. Two of the three ZIPs in this post, I lived in personally, with my own money on the line. The sub-$1M buyer who shops only one ZIP is leaving real options on the table.
Here's what actually changes when you cross each line, and which buyer fits where.
The Rectangle: What I Actually Mean
Start at the intersection of Roscoe and Balboa. Drive west to Lindley. Drop south to Saticoy. Cut back east to Balboa. That box is the seam where three ZIPs converge.
A few notes on the boundaries themselves, because this is where most online sources get sloppy. The LA Times Mapping LA project, which a lot of buyers reference, has a known inaccuracy in this area. There's a wedge at White Oak and Roscoe that drops south toward Saticoy east of Louise. Mapping LA shows it as Lake Balboa. The Lake Balboa Neighborhood Council, which is the actual governing body and the source I trust for these lines, identifies that wedge as 91325 Northridge.
Why does this matter? Because the ZIP code on your home's title affects the perceived value, the school zoning, the comps the appraiser pulls, and the search results buyers see. Getting the boundary wrong is not a rounding error. I previously served on the Lake Balboa Neighborhood Council, including as Communications Chair and Co-Chair of Planning and Land Use, and the boundary question came up constantly. The official source is lakebalboanc.org. Use that, not Mapping LA.
Inside the rectangle, the housing stock is mostly post-war single-story ranch homes built between 1948 and 1962. Three-bed, two-bath, around 1,300 to 1,700 square feet, sitting on lots between 6,500 and 9,500 square feet. That's the baseline. The differences between ZIPs show up at the margins.
What Sub-$1M Buys You in Each ZIP
I'll keep this grounded. These are the patterns I see in the rectangle, not citywide averages.
Northridge 91325 inside the rectangle: Standard stock here, original-condition or lightly updated, runs in the high $800Ks to low $1Ms. Recent rectangle comps include homes selling at $920K for 1,488 square feet and $965K for 2,334 square feet. A renovated or expanded home with a usable lot can push into the mid $1Ms.
One thing worth knowing: the housing stock in this southern slice runs smaller than what people picture when they hear Northridge. The traditional Northridge floorplans north of Plummer skew larger, with more 2,000+ square foot ranches on bigger lots. Inside the rectangle, you're more often looking at 1,300 to 1,700 square foot homes. Same ZIP, different product.
The southern slice of Northridge does not get the same premium as north of Roscoe, but the ZIP still carries weight on the listing detail page.
Lake Balboa 91406 inside the rectangle: This is where the value buyer wins. Standard stock between Roscoe and Saticoy west of Balboa runs in the high $800Ks to high $900Ks for similar specs. The 91406 median sale is around $958K with average days on market in the low thirties. Renovated homes and larger lots can clear $1M, but the bigger play here is lot size. Several streets in this slice of Lake Balboa have lots over 8,500 square feet, which puts you in ADU territory. A second unit on a Lake Balboa lot is one of the more interesting wealth-build moves available in this price band. The full ZIP context lives on the 91406 pillar page.
Reseda 91335 inside the rectangle: Standard stock in the rectangle's south slice runs in the high $700Ks to mid $800Ks. The 91335 median sold at $778K in early 2026, actually down year over year, which tells you the market is correcting Reseda harder than its neighbors. Renovated homes in Reseda cap lower than the other two, generally in the low to mid $1Ms even with significant work. The ZIP perception drag is real. But for the buyer who knows what they're looking for, Reseda is the only ZIP in the rectangle with the Fickett mid-century homes west of White Oak, and that pocket has its own pricing story.
The math: at the same square footage and condition, you can pay 15 to 25 percent more for a 91325 address than a 91335 address inside this rectangle. Whether that premium is worth it depends on what you're actually buying it for.
The School Story
This is where families have to make real tradeoffs.
LAUSD school boundaries do not follow ZIP codes. The boundary lines run mid-block in places. Two homes on the same street can attend different elementary schools. Anyone telling you Northridge schools or Reseda schools without checking the specific address is doing it wrong.
Generally, in this rectangle:
- 91325 elementaries inside the rectangle are mid-tier LAUSD options. Better than the rectangle's Reseda assignments, but not in the same conversation as the stronger Northridge schools north of Plummer, which is where most of the Northridge school premium actually concentrates.
- 91406 Lake Balboa schools inside the rectangle vary block by block. Some streets feed into well-regarded options; others do not.
- 91335 Reseda schools inside the rectangle have a wider range of ratings, with several charter options that many local families pursue.
If schools are the deciding factor, do not buy based on the ZIP code. Buy on the specific address-to-school assignment, verify it directly with LAUSD, and then check the GreatSchools rating on that specific school. The rectangle has enough variation that you can find a strong school assignment in any of the three ZIPs if you shop carefully.
Lots, Streets, and Character
Each ZIP has a distinct visual feel inside the rectangle.
Northridge 91325: Even in the southern slice, you get some of the leftover Northridge equestrian character. Wider streets, deeper setbacks, occasional horse-property zoning still on the books even where horses are long gone. Mature jacaranda and magnolia. Lots tend to run rectangular and deep.
Lake Balboa 91406: The character shifts. Streets are slightly narrower, lots are wider and shorter, and you're close to Van Nuys Airport without being directly under the landing path. The rectangle sits parallel to the approach, on the quieter side, though helicopter traffic is real and worth a daytime tour to evaluate. The ADU opportunity here is the bigger story. I've documented a four-quadrant framework for Lake Balboa elsewhere on the site, and the slice inside this rectangle sits in what I call Q2, the northwest value quadrant, where the larger lots and value pricing tend to cluster.
Reseda 91335: Denser grid, smaller setbacks, more varied housing stock. Some streets feel suburban, others feel almost urban-adjacent. The standout pocket inside the rectangle is the cluster of Fickett mid-century homes west of White Oak between Lindley and Yarmouth. Original Edward H. Fickett designs from the 1950s, post-and-beam, vaulted ceilings, walls of glass. A small but devoted buyer pool actively shops only this pocket. Renovated Fickett homes in other Valley enclaves have sold above $1.4M, but inside this rectangle's Fickett cluster, the pricing has not reached those numbers yet. That's part of what makes this pocket worth watching for the buyer who wants the architecture without paying the premium it commands elsewhere.
Honest Downsides
No real-talk piece is complete without this section. Here's where each ZIP costs you something.
Northridge 91325 inside the rectangle: You're well south of Plummer, which is where the strongest Northridge elementaries cluster. You also do not get the prestige of the equestrian zone north of Devonshire. Some buyers, and some appraisers, still treat this slice as lesser Northridge. If you're paying the 91325 premium expecting the full Northridge story, this slice does not deliver it.
Lake Balboa 91406 inside the rectangle: You're parallel to the Van Nuys Airport landing approach, which is quieter than being directly under it but still means helicopter traffic at irregular hours. Buyers underestimate this when they tour during the day. The east edge of the rectangle pushes toward Balboa Boulevard, where housing stock thins and you start running into industrial and commercial pockets just outside the rectangle's eastern boundary. The west side of the rectangle is cleaner.
Reseda 91335 inside the rectangle: ZIP code perception is the ceiling. Even renovated Reseda homes have a harder time appraising and selling at top dollar than identically renovated homes one ZIP over, and the year-over-year price correction is hitting Reseda harder than Northridge or Lake Balboa right now. School ratings drag the family-buyer pool. The Fickett pocket is an exception, not the rule. If you buy in Reseda and renovate to a high standard, you may not recover the full renovation cost on resale unless you buy in a pocket with its own architectural story.
I'm not saying any of these ZIPs is a bad buy. I'm saying every ZIP in the rectangle has tradeoffs, and the buyer who pretends otherwise gets surprised at the appraisal or the resale.
Who This Is For
Three different buyers, three different sides of the rectangle.
The 91325 Northridge buyer: Family-focused, often relocating from out of state, willing to pay a premium for the Northridge name on the deed. Sometimes this buyer is paying for prestige they're not actually getting in the southern slice. When they do their homework, they realize they can buy the same house one ZIP south and put the savings into renovation. The buyers who land here happily are the ones who specifically value the school assignment and the equestrian-adjacent street character. Both are real, but neither is universal in this slice.
The 91406 Lake Balboa buyer: Value-conscious, often a working professional or a small investor. Two profiles dominate. First, the buyer who wants more lot for the same money and is open to an ADU build over the next few years. Second, the buyer who has done enough research to know that Lake Balboa is undervalued relative to its actual location and amenity access, and who is willing to accept the helicopter-and-airport-adjacency tradeoff. This is the buyer I see doing the best long-term math in the rectangle.
The 91335 Reseda buyer: Two distinct profiles again. First, the design-driven buyer hunting the Fickett pocket. They know exactly what they're looking for, they're patient, and they pay accordingly when the right home comes up. Second, the first-time buyer who has been priced out of Northridge or Lake Balboa and is making a deliberate tradeoff to get into the rectangle at all. Both can win here. The buyer who loses is the one who buys Reseda, thinking it will appraise like Northridge in five years.
Bottom Line
The rectangle is one of the few price bands left in the West Valley where the sub-$1M buyer has real choice. Three ZIPs, three different stories, real tradeoffs in each direction.
The mistake I see most often is buyers shopping only one ZIP because they read one article or had one conversation that anchored them. The smarter move is to shop the rectangle as a whole, run the school assignment on every address you tour, look at the lot before you fall in love with the house, and let the right combination win. Sometimes that's a Northridge address. Sometimes it's a Lake Balboa lot you can put an ADU on. Sometimes it's a Fickett in Reseda you've been waiting for.
If you're shopping this rectangle and want a straight read on a specific address, the lot, the school assignment, and what the comps actually support, that's the kind of conversation I'd rather have over coffee than email. Reach me at [email protected] or (818) 697-4884.
