Common Home Inspection Findings in Southern California (What Buyers and Sellers Should Know)

Common home inspection findings can reveal costly issues before they become major problems. From roof damage to plumbing, electrical, and foundation concerns, a professional inspection helps protect your investment and gives you confidence in your home purchase.

Buying or selling a home in Southern California comes with unique challenges. From seismic activity to intense sun exposure, homes in this region experience conditions that can accelerate wear and tear. A professional home inspection helps uncover hidden issues before they become costly surprises.

Below are the most common home inspection findings in Southern California and why they matter.

1. Roof Wear and Sun Damage

Southern California’s constant UV exposure can significantly shorten the lifespan of roofing materials. During an inspection, it is common to find:

• Cracked or brittle shingles

• Loose or broken tiles

• Deteriorated underlayment

• Improper previous repairs

  
  

  Why it matters: Roof repairs can be expensive, and unnoticed damage may lead to moisture intrusion and interior deterioration.

  
  
  
  

2. Plumbing Issues and High-Water Pressure

Many homes have water pressure exceeding the recommended 40–80 PSI range. Excessive pressure can damage pipes, fixtures, and appliances.

Common findings include:

• Failing pressure regulators

• Aging supply lines

• Slow leaks

• Corrosion

  
  

  Why it matters: Small leaks can quickly escalate into major water damage and mold concerns.

3. Electrical Safety Concerns

Electrical defects are among the most important safety findings during a home inspection.

Typical issues include:

• Double-tapped breakers

• Improper wiring

• Lack of GFCI protection

• Outdated electrical panels

  
  

  Why it matters: Electrical hazards increase fire risk and should always be addressed by a qualified electrician.

  
  

4. HVAC Deficiencies

Heating and cooling systems often show deferred maintenance.

Inspectors frequently observe:

• Dirty filters

• Older units nearing the end of service life

• Damaged ductwork

• Poor airflow

  
  

  Why it matters: HVAC replacement is one of the largest expenses homeowners face.

  
  

5. Foundation Cracks and Structural Movement

Because Southern California is earthquake-prone, minor foundation cracking is not unusual. However, distinguishing cosmetic cracks from structural concerns is critical.

Inspectors look for:

• Horizontal cracks

• Stair-step cracking in masonry

• Sloping floors

• Sticking doors and windows

  
  

  Why it matters: Structural repairs can be significant, so early detection is key.

  
  

6. Drainage and Grading Problems

Improper drainage allows water to collect near the foundation.

Common findings:

• Negative grading

• Blocked gutters

• Missing downspout extensions

• Soil-to-siding contact

  
  

  Why it matters: Poor drainage is a leading cause of foundation damage and moisture intrusion.

  
  

7. Attic Insulation and Ventilation Issues

Many homes lack proper attic airflow or insulation levels.

Inspectors often find:

• Compressed or missing insulation

• Inadequate ventilation

• Signs of past leaks

  
  

  Why it matters: Proper attic conditions improve energy efficiency and help prevent mold growth.
