Pull up Altadena on any portal and you will get a different answer to the same question. Redfin puts the three-month median at $1.3M as of spring 2026. Houzeo shows $1.1M for March. The California Association of Realtors put the year-to-date median through June 2026 at $867,500. Movoto reports $1,725,000 in February. These are not typos. They are the same ZIP code measured with different definitions of what counts as a sale.
Eighteen months after the Eaton Fire, 91001 is not one housing market. It is three, and they trade on different logic, different buyer pools, and different timelines. The "median" a portal shows depends entirely on how many of each type slipped into the sample that month. Before you compare Altadena to La Cañada or east Pasadena on price, you have to decide which Altadena you are actually shopping.
Why every source gives you a different number
The gap between $867,500 and $1.3M is not noise. It is the difference between a dataset that includes vacant lot trades and one that does not. Altadena listed 348 properties or land lots in the first half of 2026, up from just one in the same period the prior year, and lot sales alone hit 172 versus six the year before. When 172 dirt trades enter the denominator, the median collapses. Strip them out and you are looking at standing-home sales in unaffected pockets, which is a different number entirely.
| Source (2026) | Reported median | What it's really measuring |
|---|---|---|
| C.A.R. YTD through June | $867,500 | All closed sales including lot trades |
| Redfin 3-month | $1.3M | Standing homes weighted toward unaffected pockets |
| Houzeo, March | $1.1M | Blended, smaller sample |
| Movoto, February | $1.725M | Skewed by a handful of high-end trades |
Altadena's year-to-date median fell 39.1 percent from $1.43 million to $867,500 in the C.A.R. reading, while Redfin's three-month figure was up 63.6 percent year-over-year because the comparison base was the immediate post-fire trough. Both are accurate. Neither tells you what a specific house on a specific street is worth.
The three markets inside 91001
The burn-zone lot market. These are parcels where the structure is gone. Pricing keys off lot size, slope, view, and how close the parcel sits to a completed rebuild. Buyers are developers, owner-builders, and patient cash buyers. Redfin data shows 287 vacant lots sold in Altadena in 2025, and just under half were purchased by investors. Named players are active and traceable: Williams Rebuild has 30 Altadena residential projects in various stages of rebuilding, and New Pointe Communities put the first of 15 replacement homes on the market at 3245 Arrowhead Drive for $1,899,990, with $20 million to $40 million in new home inventory expected to come to market over the following three months. Warmington Residential's Oak Grove Craftsman subdivision, where the fire destroyed seven of 16 homes, has been fully rebuilt or repaired, with the seven returning owners scheduled back by end of May. A lot next to a completed rebuild trades differently from a lot on a block that is still empty.
The fire-adjacent standing-home market. Structure survived, but the address sits in a corridor where buyers price in future fire risk and insurance uncertainty. This is the segment nobody wants to talk about because it is the hardest to comp. Values of homes sold in the back half of 2024 compared to homes sold since the Eaton fire are down 33 percent in the burn zones, and lots took a similar nosedive immediately after the blazes, trading at about half of their pre-fire value. Standing homes here often sell to buyers who accept the insurance friction in exchange for a discount that the unaffected pockets never see.
The unaffected pocket market. Sections of Altadena that never lost power, never took smoke damage, and never entered a debris-removal zone are trading like the pre-fire market on steroids. Inventory is starved because owners who might have sold in 2025 held off, and buyer demand for large lots, mature trees, and unincorporated-community tax and zoning treatment is still there. Houzeo showed homes moving in 40 days, inventory at 2.8 months of supply, and properties selling for 102.11% of asking in March 2026. That is a seller's market by any definition, and it is happening in the same ZIP code as $600K lot sales.
The frictions that decide which market your target address is in
Before you write an offer, six things determine which of the three markets you are actually in. None of them show up on a portal listing.
- NHD and VHFHSZ status. Altadena is a Very High Fire Hazard Severity Zone, and the Natural Hazard Disclosure will call it out. If the property or an adjacent one sustained fire damage, that is a material fact the seller must disclose.
- 2026 wildfire-map expansion. Under new state maps, more than 500 additional homes and buildings in the Eaton Fire footprint fall into the expanded wildfire building-code zone, and Los Angeles County must adopt the new zones by late July. Beginning in 2026, building requirements will expand to include properties in the "high" hazard category, meaning about 1,000 additional properties in the Eaton Fire area will be required to use wildfire building codes if their permits are approved next year. An address that was outside the code zone in January could be inside it by the time you close.
- ALE runout timing. Displacement coverage started running out for many families in Altadena by June 2025, and Additional Living Expense funds under standard 24-month policy minimums are exhausted for a second wave now. Sellers under that clock negotiate differently than sellers who are not.
- SB9 access. Pacific Palisades residents are dealing with a complete ban on SB9 development in fire-affected areas while Altadena folks still have full access to SB9's benefits, which lets you build up to four units on a single-family lot through lot splits and ADUs. For a buyer looking at a burn-zone lot, SB9 changes the underwriting. It is why the LA Times found that plans are on file for two-thirds of investor-owned parcels, 50% higher than the overall rate for Altadena.
- Lead and soil. Homeowners have reported difficulties returning due to high lead levels; one resident said returning to put things away triggered a three-day migraine, and lead cannot be 100% cleaned. Standing-home inspections in fire-adjacent corridors need soil and interior surface testing that a normal LA transaction would not order.
- Insurance availability. The California insurance market has shifted significantly since the 2025 fires, and homes with documented fire-resistant features like non-combustible exterior cladding, Class A roofing systems, ember-resistant vents, and fire-rated windows are more likely to qualify for standard market coverage. Whether your target house is insurable at a market rate is a threshold question, not a closing detail.
What this means if you are shopping Altadena this summer
The unaffected pockets are trading like the seller's market they always were, and you should expect to compete. The burn-zone lots are a specialist play. The fire-adjacent standing homes are where the pricing is genuinely dislocated and where a patient buyer with the right lender and inspector can find real value, but only if the disclosure package, the insurance bind, and the wildfire-code status all pencil.
The mistake is treating the headline median as the reference point. Home values in Altadena were down 15.6 percent year-over-year in February, compared to being down 34.6 percent six months prior, which reads like recovery. It is not. It is composition shift as more unaffected pockets sell and fewer distressed lots hit the sample in any given month. The right reference point is a comp inside the same sub-market on the same side of the wildfire map.
FAQ
Does buying a rebuilt home carry the same disclosure risk as a standing home that survived? No. A rebuilt home on a cleared lot has a fresh certificate of occupancy and permit trail. A standing home that survived carries whatever smoke, soot, and lead history the seller and their remediation contractor documented, and buyers should read those reports before writing.
If SB9 lets me build four units on an Altadena lot, does that mean I can bank on rental income? It means the parcel may qualify for a lot split or additional units. Whether the specific parcel qualifies depends on lot geometry, easements, and slope, and rental economics depend on construction cost and rate environment at the time you build. Model it before you buy.
Are the three medians going to converge? Eventually, as lot inventory clears and rebuilds finish. Not this year. Plan around the sub-market you are actually shopping.
