San Mateo County
The home has unpermitted additions or conversions
When additions, garage conversions, lower-level rooms, or other altered areas may not match public records or approved plans.
Estate representatives may inherit a property without knowing when an addition was built, whether permits were finalized, or how the space was used on the relevant date.
San Mateo County estates often involve high-value Peninsula homes, coastal properties, condominiums, hillside residences, and long-held family property with substantial appreciation.
The appraisal should distinguish known facts from assumptions and analyze how the market reacted to the property’s actual configuration and available documentation.
