Two timing questions decide how this asset is brought to market: when the seller can actually close, and what it would cost to wait and sell a processed parcel instead. This section answers both. The short version is that the land transacts now under every pathway, and that every alternative to selling as-is requires the land to appreciate substantially just to break even.

Set the routes against the calendar and the case for the most probable pathway becomes clear. The rebuild-plus-ADU program is the only development route that requires no map, no hearing, no CEQA, and no waiting period of any kind. All dates below run from September 2026 and include the permitting step separately from construction.

Seller's Path to Closing

Roughly four to six months from listing to close. Fire-lot transactions in this submarket are typically all-cash or insurance-funded, which compresses due diligence and financing contingencies relative to a conventional escrow.

Option 1 — Sell As-Is: the Date Does Not Move

The repeated column is the point. Selling as-is, the seller closes in Q1 2027 under every pathway. Entitlement time, construction time, and the January 2030 SB 1123 lookback are all risks and costs the buyer takes on after title transfers — none of them delays the sale, and none is a condition the seller must satisfy to close. The property is sold unentitled and as-is; what a buyer does with it afterward is priced into the offer, not into the escrow.

Option 2 — Entitle First: the Sale Date Follows the Entitlement Calendar

The seller is not obliged to transfer that risk. The trust could carry a subdivision entitlement itself and bring a recorded map to market, selling at a higher price to a buyer who no longer has to wait or gamble on approval. In that case the seller's sale date is no longer Q1 2027; it moves out to match whichever map is pursued.

Note what is not on this list: the 5-unit rebuild plus 5 ADUs. That right is already confirmed and ministerial — it transfers with the land at close and requires no application, no map and no waiting. Selling as-is is selling the 10-door opportunity. It is the baseline row below, not a strategy that costs time.

The question is whether the premium the market pays for a processed parcel exceeds what the delay costs. Each row below shows the full cost of waiting — consultants and County fees, holding costs, and the opportunity cost of not having net sale proceeds working at 5.50% — and the price the land would then have to fetch simply to break even against selling today.

[B] Consultant, engineering and County fees, plus holding costs, plus replacement-property income forgone over the delay period at a 6.00% cap (see below). Entitlement cost figures are planning-level estimates and should be quoted by a civil engineer and land-use consultant before this option is pursued. A final map may additionally require improvements to be constructed or bonded, which is not included above.

[C] The RTC Section 69 Prop 13 base-year transfer must be completed within five years of the January 2025 Eaton Fire — a January 2030 deadline. Replacement income assumes an all-cash acquisition at a 6.00% cap. Consult a CPA on all tax matters.

The final column carries a consequence that is easy to miss. Waiting for SB 1123 does not merely delay the sale — it forfeits the RTC Section 69 base-year transfer entirely. A mid-2030 closing lands past the January 2030 deadline, so the trust would arrive holding a valuable ten-lot entitlement and no remaining ability to carry its Proposition 13 assessment into a replacement property. A five- or six-lot tract map finishing in late 2029 fits inside the window, but with little margin for the appeal or continuance that a Commission hearing can produce.

The Return on Waiting

If the trust holds the land, the land appreciates. But holding also gives up the rent a 1031 replacement apartment would have paid. The table below runs both for each subdivision strategy — the 5-unit-plus-5-ADU program is excluded because it requires no waiting at all — and ends in the only number that matters: the return per year earned by waiting. Land is shown appreciating at 5% a year; the replacement apartment is acquired at a 6.00% cap.

Price point at sale is today’s $1,495,000 compounded at 5% a year over the wait, and reflects appreciation only — it does not include any premium for the entitlement itself, which is addressed separately below. Rent missed is net proceeds of $1,382,875 at a 6.00% cap, or $82,972 a year. ROI per year is the net divided by the $1,495,000 land value, annualized.

The Same Table if Land Moves Faster — or Not at All

The pattern is clean. If land is flat, waiting costs 5.55% a year — precisely the rent given up, with nothing to offset it. At 5% it is roughly break-even, tilted slightly negative. At 10% waiting earns 4.3% to 5.7% a year over what the exchange would have produced. Land would need to appreciate faster than about 5.5% a year for waiting to earn anything at all, before entitlement costs.

And Entitling Is Not Free

The tables above measure appreciation against rent only. They exclude what it costs to obtain the entitlement, which is the entire reason for waiting. Adding it back gives the real hurdle:

The final column is the true net divided by 0.925, because 7.5% of any additional sale price goes to commission and closing costs. Entitlement cost figures are planning-level estimates and should be quoted by a civil engineer and land-use consultant before this option is pursued.

This is the number that decides it. Appreciation roughly offsets the rent given up, so the real cost of waiting is essentially the cost of entitling — and the entitlement has to be worth more than that to a buyer.

None of these is comfortable. A four-lot parcel map must add $307,522 of value against roughly $265,000 of cost — achievable, but thin, and it yields the fewest lots. A tract map must add $435,714, earned against a Commission hearing that can condition, delay, or deny it. SB 1123 must add $505,244 while also forfeiting the RTC 69 base-year transfer. Against all of them sits the as-is sale, which closes in Q1 2027 with the 10-door rebuild right already attached and no capital at risk.

Every one of these requires the land to appreciate substantially just to break even. The cheapest, a four-lot parcel map, needs a 28% premium after roughly $389,000 of spend and 18 to 24 months. None of them is a modest adjustment to the timeline; each is a multi-year commitment of capital and risk in pursuit of a price the market has not yet demonstrated it will pay for entitled Altadena land.

The map options are a much harder case. A tract map requires the land to fetch a 42% premium after roughly $582,000 of spend and up to three years of waiting — and the risk runs the wrong way. A map that is conditioned, appealed, or denied can leave the parcel worth less than it is today, because a public record of a failed application is itself a disclosure item. Selling as-is transfers that risk entirely to a buyer who is in the entitlement business and is equipped to price it. SB 1123 is the most extreme version of the same trade: the largest premium required, on the longest wait, with the entire value dependent on a statute that has been amended in each of its first two years.

Read down the table and the breadth of the offering is the point: a buyer can be collecting rent in roughly eighteen months, selling entitled lots in under two years, or delivering finished homes in three to four — all from the same parcel, all elected after closing. That optionality is what widens the buyer pool well beyond a typical single-use land trade, and it is priced into the recommendation.

Note also that a subdivision buyer has two distinct exits, not one. Entitled lots can be sold as soon as the map records, with no vertical construction ever carried — roughly eighteen months earlier than delivering finished homes, and at materially lower risk. A buyer who wants the entitlement play without the building business has a clean route to it.

This valuation uses three distinct sets of closed sales, and the distinctions matter. Set A is the direct peer group: large, single-family-zoned Altadena land parcels — what the subject is today. Set B is the individual Altadena rebuild parcel — what a subdivision of the subject would produce as finished lots, and therefore the input to the residual analysis. Set C is completed new-construction homes — what a builder ultimately sells, which sets the ceiling on everything below it. Reading any set in another's role produces a badly wrong number.

Set A — Direct Comparables: Large Altadena R-1 Land

[1] 3430 Chaney Trail appeared twice in the MLS pull under separate listing numbers (CV25198320MR and P1-21101PF). Public records confirm a single transaction — $885,000, recorded 02/18/2026. It is counted once.

These three trades are the most direct evidence available on the subject's value. All are LCR175 — identical zoning to the subject — all are large Altadena land parcels sold for their land value, and all closed between July 2025 and February 2026. They bracket a wide range, $23.46 to $44.65 per land SF, and that spread is itself informative: it tracks subdivision potential. The top of the range, 412 W Altadena Drive at $44.65/SF, was marketed explicitly on the basis that the 27,545 SF site could be split "into 2 or possibly 3 parcels," and it cleared at 94.6% of ask in 8 days. The bottom, 603 Villa Zanita Street at $23.46/SF, sat 239 days on market.

603 Villa Zanita is the comparable a buyer's broker will lead with, and it deserves a direct answer. It is APN 5829-012-010; the subject is 5829-012-016 — the same block. At 20,037 SF it is under half the subject's size and short of the 22,500 SF needed for a three-lot R-1-7,500 split, which caps its yield at two lots. It carried no multifamily rebuild right. And it took 239 days to sell. The subject is 45,000 SF with a confirmed 5-unit ministerial rebuild right, a 10-door SB 1211 program, and a 4–6 lot conventional map. The premium over Villa Zanita is earned on yield and on entitlement, not asserted.

Averaging the three LCR175 trades gives $33.25 per land SF. Applied to 45,000 SF that indicates $1,496,000 — and the recommended list price of $1,495,000 sits essentially on that number. The subject is larger than every comp in the set, which normally argues for a per-SF discount; that pressure is offset by the fact that it is also the only parcel in the set carrying multifamily rebuild rights and a genuine path to five or more lots.

Set B — Finished-Lot Benchmark: Individual Altadena Rebuild Parcels

Set B answers a different question: what does one buildable Altadena parcel cost? Three arm's-length trades between August 2025 and April 2026 cleared at $475,000, $515,000, and $590,000. That is the number a lot developer uses to price the finished lots a subdivision of the subject would produce, and this BOV underwrites $525,000 — the midpoint — in the conventional subdivision residual.

Set B's per-SF figures must not be applied to the subject. These parcels run 4,119 to 6,625 SF and price at $115.32, $95.27, and $89.09 per land SF — a steep declining curve even across that narrow size band. The subject is 45,000 SF, roughly 8.4× the average. Applying $99.89/SF would imply $4.5M, a figure with no support anywhere in this market. Set A exists precisely to prevent that error, and the gap between the two sets — $33.25/SF against $99.89/SF — is the clearest available measure of how hard per-SF land pricing falls with parcel size in this submarket.

The subject's own assessment is not a market indicator. The 2025 roll carries a land value of $321,677. That is a Prop 13 base-year figure on a parcel held in the Hartwick Family Trust, not a current market opinion, and it should be read only as evidence that the improvements were removed from the roll following the fire.

Set C — New-Construction Resale: What a Builder Sells

Set C is the exit price for a for-sale development program, and it is the ceiling that governs what any builder can pay for land. Six of the seven sales below are Warmington Residential's "The Oak Grove of Altadena" — Tract 72939 on E Palm Street, the same street as the subject.

[2] 3010 Highview is west of Lake and reports a 1948 year built with tax and MLS square footage nearly identical — consistent with a renovation or restoration rather than a ground-up rebuild. Treated as an indication of west-of-Lake pricing, not as a new-construction cost comparable.

Two secondary observations. Lot size carries a measurable premium within the project — the same Plan 2 on a 4,572 SF lot sold at $1,699,900 while an 8,621 SF lot reached $1,780,900, roughly $20 per additional lot SF. And total price is far less elastic to house size than $/SF suggests: from 2,110 SF to 2,857 SF, sale prices move only from $1.60M to $1.78M while $/SF falls from $758 to $623. The practical implication for the subject is direct — a builder maximizes margin by building more, smaller homes rather than fewer, larger ones, which is precisely the program SB 1123 enables.

1. What Can Be Built

The 45,000 SF R-1-7,500 parcel supports a materially wider range of programs than a typical fire lot. The like-for-like rebuild of 5 units is ministerial and available now — no map, no hearing, RSO-exempt. A conventional 4–6 lot map can also be started today. And from approximately January 2030, SB 1123 opens a ministerial 10-lot subdivision with ADUs that do not count toward the statutory cap — the largest program the site supports. State ADU / JADU law layers additional doors onto whichever path a buyer chooses. All new units are exempt from County rent control.

Pathways per LA County post-fire rebuild guidance, LCR175 (R-1-7,500) standards, and California ADU / density-bonus / SB 423 law. Subdivision yield is subject to civil engineering and County map approval. Buyer to verify with LA County Regional Planning and Public Works.

2. Most Probable Pathway Pro Forma — 5 Units + 5 ADUs (10 Doors)

The program a buyer is most likely to execute: a rebuilt 5-unit building plus five detached ADUs under SB 1211, underwritten at market rents (RSO-exempt on every door). This is fully ministerial and available immediately — no map, no hearing, no waiting period.

Completed value is presented across a cap-rate band, but the base case for a merchant developer is a 5.50% exit. That is the disciplined assumption for a build-to-sell or build-to-refinance underwrite in this submarket, and it is the rate carried through the residual analysis below. The band runs 5.00% to 6.00% in quarter-point steps. The tighter end reflects a hold buyer — an owner-rebuilder, insurance-funded replacement, or 1031 buyer not underwriting a merchant exit; the wider end reflects a softer capital market at delivery.

3. Vertical Residual — What the 10-Door Program Supports on Its Own

Running the same residual discipline through the most probable pathway. The build is 5,369 SF of primary structure plus five detached ADUs at ~750 SF each (3,750 SF); ADU hard costs are modeled $50/SF below the primary structure, reflecting the lower marginal cost of detached cottage product. The base case is $400/SF all-in on the primary structure — hard and soft costs combined, per developer input current to September 2026 — with the ADUs at $350/SF all-in. Because the quoted figure already includes architecture, engineering, permits and fees, no separate soft-cost line is added. Lower cost points are shown as sensitivities.

At $400/SF all-in and a 5.50% merchant exit, the vertical build still does not support land value — the residual is negative $593,980. That remains the single most important thing for a seller to understand about this asset: a merchant developer running a build-to-rent underwrite will not be the buyer who pays the most for this site. The residual only turns meaningfully positive by combining the tight end of the exit band with a materially lower construction cost: $182,082 at a 5.00% exit and $350/SF, and $410,057 at $325/SF. At a 6.00% exit it is negative under every cost assumption.

Two things follow. First, construction cost is the dominant variable: moving from $325/SF to $400/SF all-in swings the residual by roughly $684,000 at any given exit cap. Second, the buyer's cost of capital matters as much as the program. An owner-rebuilder, insurance-funded replacement, or 1031 buyer is not underwriting a merchant profit and a near-term sale; they are underwriting a long-term hold of an RSO-exempt, ten-door, new-construction asset in a submarket that lost most of its rental stock, and they will value it well inside a 5.50% cap. The SB 1211 ADU layer remains what makes even that work — the five ADUs are the difference between a build that does not pencil and one that can.

Both readings point the same direction on land value. A vertical income build cannot, on its own, support the land value of a full acre in Altadena at a merchant exit. That is not a criticism of the 10-door program — it is precisely why the program is the most probable pathway rather than the pricing basis. Land value here is created by lot yield: 4–6 conventional parcels today, or 10 SB 1123 small lots from January 2030, each trading at what the market has demonstrably paid for a buildable Altadena parcel. The marketing implication is direct — lead with lot developers and homebuilders, who bid to the subdivision residual and to a for-sale exit, and reach owner-rebuilders and long-term holders second. A merchant build-to-rent developer is the buyer least likely to clear the price.

4. Conventional Subdivision Residual — What a Buyer Can Start Today

A lot developer's residual land value = gross finished-lot value − (subdivision and infrastructure cost + entitlement carry + developer profit). Finished-lot value is taken at $525,000, the midpoint of the three closed Altadena fire-parcel trades ($475K / $515K / $590K). The base case is a 5-lot tract map begun immediately.

Across both sensitivities the conventional residual brackets $1.03M to $1.68M, clustering at roughly $1.35M in the base case. This is the value supported by what a buyer can start today.

5. SB 1123 Residual — The 10-Lot Maximum-Value Case

The same discipline applied to the SB 1123 pathway. Ten fee-simple parcels averaging 4,500 SF each — smaller than the 5,400–6,600 SF comparable parcels, and therefore underwritten at a discount to them — with ministerial approval, no CEQA, no hearing, and no affordability requirement. The trade-off against the conventional map is more lots at lower value each, higher infrastructure cost, and a longer hold to the January 2030 unlock.

The SB 1123 residual brackets $1.53M to $2.33M against the conventional pathway's $1.03M–$1.68M — an uplift of roughly $575,000 at the midpoint, and that is before crediting the ADU layer, which adds up to ten more doors at no cost to the 10-unit cap. Note also what the table does not charge for: no discretionary map risk, no CEQA exposure, no hearing, and no possibility of a hostile condition of approval. On a risk-adjusted basis the gap is wider than the raw numbers show.

This BOV does not adopt the SB 1123 residual as the base case. Two inputs carry real uncertainty — the small-lot value (there is no closed 4,500 SF Altadena lot trade to anchor it) and the four-year statutory wait, over which the law may be amended in either direction. The reconciliation in the Pricing section weights the conventional pathway 60% and SB 1123 40%, which is the posture we would defend to a buyer and to an appraiser.

6. Exit Structures — Rental vs. For-Sale

The question every developer asks on the first call: can the units be built and sold off individually? The answer turns on a single point of law that materially shapes which pathway a buyer chooses.

The finding that matters: SB 1123 is the only pathway that produces ten individually sellable units. Nothing available today gets past six. That reframes the statute's value on this site — it is not merely "more doors," it is the only for-sale structure at scale, and fee-simple homes command a premium over the sum of rental doors. It is also why the January 2030 date is worth tracking rather than dismissing.

The strategic split is therefore cleaner than it first appears. The 5-unit-plus-5-ADU program is a hold play — ten doors, ministerial, income from day one, RSO-exempt, no map, no waiting. It is the right structure for an owner-rebuilder, an insurance-funded replacement buyer, or a long-term holder, and the wrong structure for a merchant sell-off. Any for-sale exit requires a subdivision, and fee-simple is the cheaper path: no HOA, no CC&Rs, and no DRE public report below five lots.

7. Build-and-Sell Cross-Check

The Set C comparables make it possible to test the subject directly against a build-and-sell exit — the program a merchant homebuilder actually runs. The structural advantage over an apartment build is large and worth stating plainly: a completed home sells at roughly $620–$650 per SF of building, while a stabilized apartment at a 5.50% cap is worth about $399 per SF of building. Construction cost per SF is broadly similar. Retail pays roughly 1.6× per square foot built, and that single fact is why the buyer pool for this site is homebuilders rather than apartment developers.

[3] Home prices for 2,100 SF and 1,600 SF product are extrapolated from the observed Set C size gradient, not directly observed; no Altadena new-construction comparable below 2,110 SF was available. [4] 10%/yr is shown against the 10.7% annualized rate actually achieved on Warmington's Plan 2 between October 2025 and July 2026.

Three conclusions follow, and together they reconcile the recommended price from a direction entirely independent of the land comparables.

First, product size decides the deal. Holding lot count, hard cost, and margin constant, shrinking the house from 2,700 SF to 2,100 SF moves the indicated land value by roughly $460,000 — because Set C shows total sale price is far less elastic to size than cost is. Building large destroys margin in this market.

Second, a builder underwrites to delivery, not to today. A conventional map takes 18–30 months, so a builder acquiring now delivers into the 2028–29 market. At the appreciation rate Warmington has actually realized, the right-sized 5-lot program indicates $2,142,957 — comfortably above the recommended list price. Underwritten at flat 2026 pricing it indicates $839,923, and at a more modest 5%/yr it indicates $1,475,927 — essentially the list. The gap between those two numbers is the price trend, and the price trend is observed rather than assumed.

Third, SB 1123 clears by a wide margin. Ten smaller homes indicate roughly $2.97M of land value at today's pricing, with no appreciation required — the highest indication produced by any lens in this report, and further support for treating the January 2030 pathway as real value rather than speculative upside.

California Revenue & Taxation Code Section 69 provides a significant tax benefit for owners whose property was destroyed in a Governor-declared disaster: you can sell this land and transfer your existing Prop 13 base year value to a comparable replacement property within Los Angeles County — preserving your low property tax assessment on the new property rather than being reassessed at today's market value.

This is particularly relevant here. The 2025 roll carries a base-year land value of $321,677 and an annual tax bill of $5,090.02 on a parcel held in the Hartwick Family Trust — an unusually low basis reflecting decades of Prop 13 protection. Transferring that base year value to a replacement property, rather than surrendering it, is likely the single largest ancillary economic consideration in a sale of this asset.
