Historical Home

A home may be considered historical based on (a) age alone (typically 50+ years), (b) architectural significance (Craftsman, Spanish Colonial Revival, Mid-Century Modern, etc.), (c) historical designation (HPOZ, Mills Act contract, National Register), or (d) cultural/event significance. In Los Angeles, neighborhoods like Hancock Park, Windsor Square, West Adams, Angelino Heights, and Bungalow Heaven contain concentrations of architecturally and historically significant homes.

The Mills Act provides property tax reductions (often 40–60%) in exchange for owners maintaining historical features. The tax savings can materially increase home value because the lower tax burden increases what buyers can afford to pay. In appraising a Mills Act home, we analyze: the contract terms, the annual tax savings, the remaining term, and the buyer-pool premium for Mills Act homes vs equivalent non-Mills properties. The Mills Act adjustment is often substantial in qualifying neighborhoods.

HPOZ designation imposes design review requirements on exterior modifications and additions. This typically: (a) preserves neighborhood character and supports value, (b) restricts certain renovations or expansions, and (c) requires HPOZ board approval for material changes. We analyze HPOZ comparables to derive the market premium or discount, which varies by HPOZ neighborhood. In neighborhoods like Hancock Park, the HPOZ premium is significant; in others it’s more neutral.

Alterations that compromise historical integrity (removed period windows, vinyl siding over original wood, modernized facades) typically reduce value in markets that prize historical authenticity. We document the original vs altered features and analyze comparable sales of similarly altered homes to derive the value impact. In some cases, reversal of alterations can be supported as a value-additive renovation.

They can be. Lenders may require additional documentation for older systems (electrical, plumbing) and unique construction. Insurance can be more expensive due to higher replacement costs for historical features. These factors don’t typically reduce value but can affect time-to-close. Our appraisal documents the property’s condition and any system updates so the lender and insurer have what they need.
