Pricing a Danville home starts with deciding what another property actually demonstrates. Similar interior area and a nearby address are useful filters, but neither establishes equivalent usable land, ownership rights, completed improvements or maintenance exposure. The relevant question is whether a buyer could substitute one property for the other after understanding those differences. Public records can improve that comparison before a qualified pricing professional obtains the closed-sale evidence. This guide uses actual Town examples to build that screening process; it does not claim an empirical valuation from sales that were not supplied.
Define the subject before selecting a radius
Begin with the subject parcel, its jurisdiction and the interest being sold. The Town Permit Center instructs applicants to confirm that the work site lies inside Town boundaries. A Danville mailing address alone is not enough to select the permit authority. Write down the parcel identifier, legal ownership form, documented interior areas, parking rights, outdoor areas and any shared infrastructure. Then mark each characteristic as established, reported by another party or still unresolved. That distinction becomes the admission standard for potential comparables.
The standard should reflect the buyer’s practical alternatives. A house with extensive grounds may offer private outdoor utility that a condominium does not, while an attached unit may shift some exterior obligations to an association. Neither difference creates a universal premium. Compare the rights and responsibilities the actual buyer receives. If a smaller site provides the needed outdoor use without the same access or maintenance demands, raw lot size may explain less than the listing suggests. That is a question for evidence, not a reason to impose an automatic adjustment.
Resolve area fields before calculating price per square foot
The public detail for B24-018239 at the El Pintado example illustrates the problem. Its description refers to a 6,016-square-foot residential scope and 950 square feet of covered patio, while a separate Square Feet field displays 7,866. The record shows Issued status without a finalized date as checked October 26, 2026. Those fields do not establish a marketable living-area total. Obtain the approved area schedule and identify what each field includes before placing any of those numbers in a pricing denominator.
A spreadsheet can make an uncertain measurement look authoritative simply by dividing a price by it. Keep alternative area definitions separate until the source is resolved. Covered patios, garages, dwelling area and other spaces should retain their documented labels rather than being combined because they share a permit. If a candidate sale’s published area cannot be reconciled, mark that limitation and consider whether it can still answer a narrower question. A verified sale price cannot repair an unreliable denominator, and a permit’s administrative valuation cannot substitute for a sale price.
Distinguish earlier finals from current construction
The Town’s public parcel search returns separate historical scopes at 562 El Pintado Road unit A. It lists an earlier addition final in August 2021, a roof final in October 2021, solar in November 2021 and HVAC in December 2021. Those milestones are useful evidence for their respective projects. They do not final the newer residential project, establish that equipment remains unchanged, or describe the condition visible to a buyer today.
For each candidate, compare the state of work at the time of its sale with the subject’s state at the proposed pricing date. Completed work, an issued construction scope and a concept awaiting approval are different offerings. A purchaser of unfinished work may face remaining inspections, contracting decisions and a different schedule. Do not convert those uncertainties into a guessed percentage discount. Request the remaining scope, documented costs, contractual arrangements and relevant sale evidence. A complete home and an unfinished project can inform one another, but their relationship needs explanation.
| Screen | Local evidence that makes it necessary | Admit when | Hold open when |
|---|---|---|---|
| Interior-area definition | B24-018239 has differently framed description and Square Feet fields. | Area source and included components can be reconciled. | A permit field is being treated as verified living area. |
| Completion at relevant date | 2021 scope finals coexist with newer Issued building and wall records. | Sale-date and subject-date work states are described separately. | An old final is being applied to a new project. |
| Usable site and wall scope | Planning material describes 9 feet 2 inches; wall permit describes 12 feet 6 inches. | Approved sections explain the relevant measurements and scope. | Difference is guessed to be a defect, extra yard or extra living area. |
| Ownership and shared systems | 600 Hartz is a mixed-use condominium setting; Corte Dorado records discuss different drainage arrangements. | Actual unit/parcel rights and obligations are established. | Project reports are substituted for private agreements or HOA finances. |
| Transaction evidence | No permissioned closed-sale dataset supplied for this article. | Source, date, status, terms and property identity are verified. | Asking price, tax assessment or permit valuation is being called a closed sale. |

Translate site differences into questions a buyer can answer
The wall record W25-000857 describes a maximum height of 12 feet 6 inches and 514 linear feet. The Town-posted draft September 22 action summary concerns a variance described through a different, 9-foot-2-inch height. The draft summary reports approval but remains a draft posted for October 27 consideration. Neither source explains the measurement difference by itself. Request the approved sections instead of treating the difference as evidence of a violation, a constructed feature or a pricing adjustment.
The practical site comparison follows from that clarification. Which outdoor areas are accessible from the house? What portion serves everyday use, and what portion supports drainage, circulation or slope management? Who can reach a component for maintenance, and through whose land? These questions can produce meaningful distinctions between similarly sized lots. Record the document or observation that supports each answer. Keep current condition separate from proposed design and avoid estimating usable square footage from a conceptual project image or an unmeasured aerial view.
Do not transfer one project’s engineering conclusion to another home
The published Martin Hills geology appendix contains dated investigations and peer review with project-specific assumptions, additional recommendations and validity limits. Its discussion of slope drainage and district documentation can help frame a request for relevant evidence. It cannot diagnose the current condition of every nearby property. The October response document also differentiates proposed project systems from existing Corte Dorado arrangements.
Accordingly, do not exclude every nearby sale because a report discusses a site issue, and do not assume every nearby sale shares the proposed project’s mitigation. Establish the subject’s actual relationship to the relevant system, agreement and investigation. The Town’s current update schedules Martin Hills review for October 27, 2026, after this research date. Proposed future homes are not completed comparable inventory. Their plans may help identify a changing setting, but they do not supply closed-sale evidence or completed improvements.
Keep the transaction and property dates aligned
For each potential sale, preserve a short chronology: the reported contract and closing dates, the evidence date for condition, and the improvement milestones known before closing. A renovation completed later cannot explain the earlier transaction as though buyers received it then. Likewise, a current photograph may show a feature absent from the sale offering. Ask the transaction source to clarify concessions, included property and unusual terms before comparing headline prices. Where those details remain unavailable, retain the sale as a limited observation rather than manufacture a net-price calculation.
Build a second, smaller set of alternatives that the likely buyer could actually substitute, then explain why each is included. It may contain fewer properties than a broad radius search. If the result depends heavily on one uncertain candidate, show that dependence to the pricing professional and seek another source or comparison. Expanding distance without explaining changes in ownership form, site use or work status can increase the number of rows while weakening the conclusion. A transparent admission decision is more useful than a precise-looking average of unlike offerings.
Screen attached alternatives on their actual rights
The Town’s June 2025 update for 600 Hartz Avenue identifies completed condominium residences, with commercial tenant improvements in a separate phase. A downtown mixed-use setting introduces different evidence needs from a detached hillside house: the unit’s legal interest, assigned parking, access, shared structure, association expenses and the boundary between commercial and residential responsibilities. The update supplies no private unit’s current availability, financial position or parking entitlement. Request those documents before treating a condominium as a cheaper or more expensive substitute.
The two El Pintado and Corte Dorado annual tax accounts similarly describe existing charges rather than market values. Use them to identify operating questions, then estimate a purchaser’s expenses separately. To finish a pricing opinion, obtain permissioned transaction records, verify terms and timing, and explain the remaining comparability limits. The Danville guide, Contra Costa County guide and selling process provide the broader context for assembling that evidence with the appropriate professionals.
