How to Tour Open Houses in SoCal Like a Pro (Checklist Inside)

Most buyers treat open houses as casual browsing. Smart buyers treat them as intelligence-gathering operations. Here is how to tour homes in Southern California like someone who has done this 100 times.

Before you walk in

• Pull the permit history using the address on your county's building department website. Any significant unpermitted work is a liability you inherit.
• Check the listing days on market. A home sitting for 45+ days in SoCal usually has a problem — price, condition, or location. Ask why.
• Look up the property tax record. The listing will show taxes; the actual bill on county assessor sites shows you the full picture including any Mello-Roos.
• Drive the neighborhood at different times. Sunday at 11am and Thursday at 6pm are very different experiences in many SoCal neighborhoods.

What to examine inside

Foundation and structure

• Cracks in walls, especially diagonal cracks at window corners — can indicate settling or seismic movement
• Doors that stick or do not close properly
• Floors that slope — roll a marble if you are unsure
• Signs of past water intrusion: stains on ceilings, bubbling paint near baseboards, efflorescence (white mineral deposits) on concrete

Roof and exterior

• Ask when the roof was last replaced and get the documentation
• Look at the gutters — overflowing or improperly sloped gutters direct water toward the foundation
• Check stucco for cracks, especially at roof-to-wall junctions
• Look at the garage slab — oil stains suggest a leak, cracks suggest settling

Systems

• Run every faucet. Check water pressure and drainage speed.
• Turn on the HVAC. Listen for unusual noises. Check the filter — a dirty filter suggests deferred maintenance.
• Locate the electrical panel. Federal Pacific and Zinsco panels are fire hazards and will need replacement.
• Ask the age of the water heater, HVAC, and roof. Budget replacements accordingly.

California-specific concerns

• Seismic retrofitting: Was the home bolted to its foundation? Pre-1980 homes in earthquake zones often were not. Ask for the retrofit documentation.
• Wildfire risk: Check the property on the CalFire Fire Hazard Severity Zone map. In a Very High FHSZ, insurance is a serious issue before you make an offer.
• Flood zone: Check FEMA flood maps. Coastal and low-lying areas may require flood insurance.

What to ask the listing agent

The listing agent works for the seller — but they must answer honestly when asked directly:

• "Are there any known material defects you are required to disclose?"
• "Has there been any water intrusion or mold history?"
• "Are there any pending HOA special assessments?"
• "What offers have been received and declined, and why?"
• "What is the seller's ideal closing timeline?"
