Pricing a Los Altos Hills home requires a comparison of the residence and the working site together. Interior area, useful grounds, driveway access, supporting improvements, service arrangements and recorded rights can distinguish properties that share a broad acreage or room-count description. A large parcel is not a single uniform product. The useful question is which verified transactions explain the actual rights, utility and condition being offered, rather than which broad average produces a convenient asking price.
No permissioned closed-sale dataset, publication rights or named broker-authored case study was supplied for this draft. It therefore presents a complete local comparable-admission method and an original public-record case file. It does not report actual comparable sales, an empirical market trend, a price range or measured adjustment coefficients. The examples show the evidence a later authorized valuation should obtain without relabeling planning records as transactions or inventing a professional review.
Describe the actual subject before choosing the sample
Record the residence’s current layout and documented area, together with garage, accessory buildings, parking and useful outdoor spaces. Identify the actual route from vehicle to entrance and between the main living area and the grounds the household expects to use. Preserve the source and definition of every material area figure. A home’s marketed living space, Town floor-area account and total parcel acreage answer different questions and should not be substituted for one another.
List the material rights and obligations from the actual file. Where an access, pathway, utility or open-space easement matters, obtain the recorded document and appropriate interpretation. A visible driveway does not establish every right needed to use or maintain it. Likewise, open-looking land does not establish that it can be graded or developed. The subject description should identify what is documented and leave the unresolved question visible rather than converting an impression into a property right.
Separate present utility from a planning maximum
The Town’s July 8, 2026 MFA/MDA/PWB instructions distinguish floor area, development area and parcel water-budget calculations. These are important local planning concepts, not direct market-value measures. A comparable analysis should use the correct current property definitions and identify whether it is discussing existing space or a proposed project. A calculated maximum should not be marketed as completed or automatically approvable area.
For a candidate sale, reconcile its useful existing grounds and actual improvements with the subject before considering future capacity. A parcel with a well-connected outdoor arrangement may serve buyers differently from one requiring a substantial project to achieve a similar use. The analysis needs evidence for that difference, not a universal slope or acreage coefficient. No dollar adjustment for additional development allowance is measured here.
The current Town instructions also recognize site-specific limitations. If future work is central to the comparison, obtain the actual current review and relevant conditions. A smaller nominal maximum does not necessarily make a home less suitable for a particular household, and a larger one does not show that a desired combination of residence, accessory use and outdoor features can be approved. Keep that planning uncertainty separate from the documented present home.
Read the Alicante case without making it a comparable transaction
The Town’s 2022 report identifies SD21-0088 at 25959 Alicante Lane and reports approval with conditions of a multi-feature site-development project. Its public 2021 drawing cover identifies APN 175-34-038 and an earlier planning snapshot. These are actual local records. Neither provides a closed-sale price or independently establishes the present configuration and completed improvement area.
The case shows why a record chain matters. A project can include a residence, basement, accessory unit and outdoor features while its current constructed form still needs verification. For actual subject and candidate homes, obtain the controlling revision, conditions, building scope and relevant completion evidence. A later sale should be analyzed according to what was actually transferred at that time, rather than every feature appearing in a historical plan or summary.
Do not use a planning worksheet to resolve a different living-area measurement by assumption. Identify how each source counts the garage, basement, accessory building or other material component. If the definitions cannot be reconciled, keep the candidate’s price-per-area calculation out of the core conclusion until the discrepancy is understood. A mathematically correct quotient can still be misleading when its denominator describes a different property feature.
| Admission question | Local research anchor | Required actual sale evidence | Limit |
|---|---|---|---|
| Which area is being compared? | July 8, 2026 Town MFA/MDA/PWB accounts differ from general acreage/living-area descriptions. | Current subject/candidate definitions and reconciled measurements. | Planning maximum is not existing living space or guaranteed capacity. |
| Which project version was built? | Alicante APN 175-34-038: 2021 cover and reported 2022 SD21-0088 approval. | Controlling revisions, actual completion and condition at transaction date. | Historical proposal is not a comparable sale or current inspection. |
| Which rights and conditions apply? | Nina Place SD21-0061 contains an open-space grant requirement. | Actual recorded grant, boundaries and relevant later project evidence. | Condition does not prove recording, current deficiency or universal restriction. |
| Do services and obligations match? | Town lists two water retailers and distinct OWTS review route. | Actual provider, wastewater system and material obligations for each property. | No standard service package or automatic market penalty inferred. |
| Is the transaction usable? | Authorized actual closed-sale source, rights and verification still required. | Date, consideration, property rights, relevant condition and sample/exclusion rules. | No fabricated transaction, trend, price range or dollar coefficient. |
Source anchors: current Town instructions, Alicante report and Nina Place historical conditions. Add permissioned verified sales and appropriate review before drawing a property-specific value conclusion.
Verify recorded site obligations without inventing a discount
The historical SD21-0061 conditions at 26875 Nina Place include an open-space grant requirement and later site evidence. That requirement is not independent proof of the recorded document’s final form or present completion. For actual comparisons, obtain the relevant grant and current record rather than treating the historical condition as either an unfulfilled obligation or a universal restriction applying to nearby parcels.
Match the subject and candidates by their real use and responsibilities. A recorded restriction can matter without producing a fixed market penalty. A private supporting improvement can be important without being defective. Establish the actual condition and scope before discussing how it relates to buyer response. Do not transform a consultant’s recommendation, contractor estimate or public infrastructure cost into a dollar-for-dollar price adjustment without transaction evidence supporting that treatment.
Keep provider differences and physical findings in separate roles
The Town’s utility directory identifies Purissima Hills Water and California Water Service. Its OWTS page directs septic permitting to County Environmental Health and identifies project-related sewer questions. For a sale candidate, verify the actual water provider and wastewater arrangement. Do not assume identical bills or future project requirements from the Town label alone.
A service arrangement is not a condition rating. A sanitary connection does not establish the state of a private lateral, while a septic maintenance record does not automatically authorize every proposed change. Ask what was known and documented about the actual system at the relevant transaction date. If a material question remains unresolved, disclose its effect on the comparison rather than creating an arbitrary adjustment intended to cover every possible outcome.
Disclose the dataset and comparison boundaries
When authorized sales data becomes available, identify the actual period, property types, geographic boundaries and number of verified closes. Explain how the transactions were verified and which information may be published. Separate closed sales from active asking prices, rental offers, pending contracts and planning announcements. Public records can support a property’s identity or improvement history while remaining unsuitable as evidence of the consideration paid.
If the sample needs to include nearby Los Altos or another jurisdiction, identify that expansion and the actual differences relevant to the subject. Do not silently transfer Town rules or service arrangements to a neighboring-city property. Keep candidates with uncertain area, rights or condition in a separate supporting group until their material discrepancies are reconciled. A wider sample should make the analysis more transparent, not obscure the reason each transaction is relevant.
Explain adjustments and reconciliation in proportion to the evidence
For any real adjustment, disclose its direction, amount and supporting reasoning separately. Avoid multiple allowances describing the same underlying difference, such as useful outdoor area and a site project needed to create it. If the available sales do not isolate a feature’s effect, acknowledge that limitation and weigh the comparison accordingly. Precision in the final arithmetic cannot repair unsupported inputs or make a narrow sample establish a broad market trend.
Reconcile the most relevant verified candidates according to their evidence quality and match to the subject’s present utility. State which findings or records could materially change the conclusion. A price discussion should distinguish a documented home from a hoped-for project without promising that every improvement cost will be recovered. Appropriate professional review remains necessary for the property-specific conclusion absent from this methodological draft.
Use the selling-process guide, the Los Altos Hills hub and Santa Clara County guide to organize that next analysis. The original case file makes the local evidence requirements visible while leaving actual value, market effects and measured adjustments open until authorized relevant transaction evidence exists.
