Top Home Inspection Issues in California Homes
1. Roofing Problems
Why it happens:
California’s sun and seasonal rains wear out roofing materials—especially on homes older than 15–20 years. Clay tile and asphalt shingles are common but may hide water damage or improper installation.
What to do:
Request a roofing inspection if wear is noted. Moderate wear isn’t a dealbreaker, but active leaks or structural damage may warrant a seller credit or roof replacement before closing.
2. Foundation Cracks & Settlement
Why it happens:
Soil movement, seismic activity, and drought contribute to foundation shifts. Cracks in slab or raised foundations are common, especially in older homes.
What to do:
Hairline cracks are usually cosmetic. Major settlement or sloping floors require further evaluation. A foundation specialist can estimate repair costs and risk level.
3. Plumbing Issues
Why it happens:
Many older homes in California still have galvanized or clay pipes, which corrode, clog, or leak over time. Newer homes aren’t immune either—PEX piping can suffer from poor installation.
What to do:
Request a sewer scope (especially for homes built before 1980). Minor leaks can be patched, but full repiping or sewer replacement is a major cost—and a powerful negotiation point.
4. Electrical Panel Concerns
Why it happens:
Outdated panels like Zinsco and Federal Pacific are common in California homes built before 1980 and are known fire risks. Missing GFCI outlets and overloaded circuits are also red flags.
What to do:
Panels can be replaced—budget $1,500–$3,500 depending on scope. Don’t skip an electrician review if the inspection flags wiring concerns.
5. HVAC System Deficiencies
Why it happens:
Air conditioning is essential in many parts of CA, but HVAC systems are often underserviced or sized incorrectly—especially in flips or remodels.
What to do:
Check the age and service history of the system. If it’s over 15 years old or blowing weak, factor replacement costs into your offer.
6. Termite Damage & Wood Rot
Why it happens:
Warm climates and older construction make termite infestations common. Wood rot, especially around exterior trim or decks, is another widespread issue.
What to do:
Termite inspections are routine and often required. Treating infestations is affordable; structural damage is more serious and should be repaired by the seller.
How to Handle Inspection Issues Like a Pro
Don’t Panic—Prioritize
Not every item is a dealbreaker. Prioritize health, safety, and structural issues first. Cosmetic fixes can wait.
Negotiate Smartly
Use the inspection report to request:
- Seller repairs before close
- Credits toward closing costs
- Price reductions based on repair quotes
Bring in Specialists
Your general inspector might flag an issue, but foundation pros, electricians, or roofers provide deeper insight. Use their estimates to guide negotiations.
Understand Local Code Requirements
California has evolving building codes—especially for seismic safety, energy efficiency, and water conservation. You may be required to upgrade during resale or renovation.
