Landfills

No disclosure law obligates anyone to mention a nearby landfill, and closed sites keep producing gas for decades. Learn how to find every site before you tour, when the measured price discount is real leverage, and when the right answer is simply walking away.

Gas Pipelines

Catastrophic pipeline failures are rare; the everyday reality is the easement, which can decide your ADU, pool, and landscaping before you ever move in. Learn how to sort the real risks into buckets, why quiet proximity carries no market discount, and what to read in title before you commit.

California Wildfire Risk

In a high fire-hazard zone, insurability is the real gate, and the home itself matters as much as the zone: the roof, the vents, and the first five feet decide most ember losses. Learn which hardening steps pay off in insurance discounts and how zone status becomes a fair reason to negotiate.

Superfund and contaminated sites

A nearby Superfund site is a screening signal, not exposure, and active versus cleaned-up changes everything. Learn how to read a site's history and land-use covenants, when to bring in the professionals, and how to weigh the stigma that can outlive the cleanup.

Power Lines

After decades of research, the health evidence on power lines stays inconclusive; the factors that really affect a purchase are practical. Learn what the easement in title can restrict, what to check standing on the lot, and how to price the next buyer's perception into your negotiation.

Landslide

Hillside views are priced in; the slope risk often is not. Learn when a landslide zone calls for your own geotechnical read, why drainage is the trigger you actually control, and why standard homeowners insurance excludes earth movement entirely.

FEMA Flood Zones

Flood insurance is a permanent carrying cost, and about a third of flood claims come from outside high-risk zones. Learn how to size up a home's flood zone before you offer, when the paperwork can lift a mis-mapped home out of the zone, and why a mapped zone is a negotiating lever rather than a walk-away.

California Earthquake Fault and Liquefaction Zones

Fault rupture and liquefaction are different problems with different fixes, and both are more manageable than they sound. Learn what to look for in the soils report, what mitigation actually involves, how CEA earthquake coverage works, and why in-zone status is a price lever rather than a deal-breaker.
