Hard-to-Insure Homes in San Francisco: What Buyers and Sellers Need to Know

San Francisco’s historic charm comes with a catch: older homes often feature structural or system quirks that can raise red flags for insurance providers. From aging wiring to unreinforced foundations, these issues may spike premiums—or even make a property uninsurable. Below are some common insurance “deal breakers” to watch for, along with practical tips for both buyers and sellers.



1. Knob and Tube Wiring

What Is It?Knob and tube wiring is an older electrical system typically found in homes built before the 1950s. Unlike modern romex wiring, knob and tube is more prone to fire hazards due to outdated insulation.

Why Insurance Providers Dislike It

  • Increased risk of electrical fires

  • Many insurers refuse coverage until a home is rewired

Advice for SF Buyers and Sellers

  • Selling? Consider rewiring ahead of listing to avoid scaring off potential buyers.

  • Buying? Budget for possible rewiring if the home inspection flags extensive knob and tube wiring.



2. Brick or Partial-Brick Foundations

Historic Prevalence in San FranciscoMany early-1900s properties—especially Victorians—feature brick or partially brick foundations. While these lend a timeless appeal, they may be less stable in earthquake-prone regions.

Earthquake Concerns

  • Unreinforced brick can pose structural risks.

  • Some insurance carriers require proof of bolting or seismic retrofitting before issuing a policy.

Landfill vs. BedrockLarge sections of San Francisco sit on landfill, which can amplify seismic activity. Buyers should confirm whether a property is on bedrock or landfill using the city’s Property Information Map (PIM). This factor can influence insurance premiums and coverage options in top neighborhoods like Pacific Heights, Noe Valley, or the Richmond District.



3. Old Roofs

Red Flag for InsurersA roof nearing the end of its lifespan (often 20–25+ years) may trigger higher premiums or coverage denials, especially in a city prone to wet winters.

Water Damage RisksLeaks can lead to mold and structural issues—major expenses for insurance companies.

Advice for Sellers and Buyers

  • Sellers: If the roof is aging, replace it or obtain a professional certification that it’s in solid condition.

  • Buyers: Factor potential roof replacement into your total purchase costs, especially in popular but older areas like the Sunset or the Mission.



4. Lack of Earthquake Retrofitting

San Francisco RealityEarthquake insurance can be expensive in any part of the Bay Area, but a home with no seismic upgrades may be even pricier to insure—or outright uninsurable.

Retrofitting Perks

  • Bolted foundations and reinforced cripple walls may reduce premiums.

  • Documented retrofits add value and peace of mind in top neighborhoods in San Francisco with older housing stock.



5. Home Security Matters

Lower Rates, Fewer RisksWhile security systems don’t top the list of absolute deal breakers, many insurers offer discounts for monitored alarms, camera systems, or advanced locks.

Easy UpgradesModern smart home solutions, like doorbell cameras, not only improve safety but can also enhance marketability when selling in sought-after communities.



Turning Challenges into Opportunities

  1. For Sellers:

    • Tackle these issues before listing to showcase a ready-to-insure property.

    • Transparency about upgrades can help position your home competitively in best neighborhoods in San Francisco like Cole Valley, Bernal Heights, or Presidio Heights.

  2. For Buyers:

    • Review disclosure documents carefully to spot red flags, from old wiring to unretrofitted foundations.

    • Factor renovation and insurance costs into your budget. A well-informed purchase in the right neighborhood can help ensure a smoother transition.
