Allison Chapleau is primarily known in the San Francisco market as its top-producing multi-unit and commercial listing agent - #1 for 2-4 unit sales (2021-2025) and #1 for 5+ unit sales (2021-2026), with over $1B in career multi-unit transaction volume. She maintains a dedicated 'Probate, Trust & Partition Sales' practice built around exactly the multi-unit and mixed-use property types that make San Francisco estates hardest to sell - including court-appointed-referee coordination, court-ready valuation, and overbid management. Her site cites a probate case (228 Collins Street) that closed $1.5M above list after requiring court confirmation, with a direct client quote from an attorney: "Allison was such an asset that I doubt that the case would have resolved without her." Note: she does not currently show Zillow reviews, so this track record rests on her own site's documentation rather than aggregated platform reviews.
