San Francisco Home Budget Calculator

San Francisco is a compact, high-density City and County where a large share of the housing stock is condominiums, tenancies-in-common, and older Victorian and Edwardian homes rather than new construction. Prices sit among the highest in the nation - Zillow pegs the typical home value near $1.4 million, while Redfin has reported recent median sale prices around $1.7 million - which means most buyers face jumbo-loan territory above the county's high-cost conforming limit. Beyond price, buyers weigh seismic considerations tied to the region's active faults and liquefaction zones, condo/HOA and TIC financing nuances, and an effective property-tax rate of roughly 1.18% under California's Proposition 13 framework.

Why insurance moves the number here: Earthquake is San Francisco's dominant natural hazard: the San Andreas and Hayward faults drive strong ground-shaking risk, and roughly a quarter of the nine-county Bay region sits in mapped liquefaction zones, including bayfront and former-landfill areas such as the Marina, SoMa, and Mission Bay; the city enforces seismic requirements including its soft-story retrofit program. Wildfire risk inside the dense city limits is comparatively low - most of San Francisco is a Local Responsibility Area with limited Very High Fire Hazard Severity Zone acreage under CAL FIRE mapping - but statewide insurer pullback has pushed many Californians toward the CA FAIR Plan, the state's insurer of last resort (roughly 684,000 policies in force as of March 2026), which can affect availability and cost of coverage. Flood exposure is concentrated along the bay shoreline and low-lying reclaimed land, with FEMA flood zones, sea-level-rise projections, and coastal tsunami evacuation zones relevant to waterfront properties. Buyers should confirm current hazard-zone status and insurance availability for any specific address. Wind exposure is a large part of why a San Francisco payment can differ from the same price elsewhere, so the insurance figure above is doing real work in the total.
