Buying your first home is exciting — and a little nerve-wracking. One of the most important steps before you hand over any money is the home inspection, and it’s worth understanding what it actually involves before you’re standing in someone else’s kitchen wondering what the inspector is writing down.

Here’s what you need to know.

What a Home Inspection Actually Is

A home inspection is a visual, non-invasive walkthrough of a property carried out by a certified professional. They’re not there to tell you whether to buy the home — that’s your call. What they are there to do is flag any “material defects”: problems that could significantly affect the home’s value or, more importantly, your safety.

In San Diego, home inspections happen in roughly 90% of real estate transactions. They’re not legally required, but skipping one would be an unusual risk to take.

The inspector will work through the home’s main systems: the foundation and structural framing, the roof, exterior walls and windows, plumbing, electrical panel and wiring, heating and cooling, and the interior spaces including stairs, ceilings, and built-in appliances. They use tools — ladders, moisture meters, circuit testers — and they get into spaces most buyers never look at.

What they won’t do is dismantle anything, evaluate cosmetic issues, or test systems that have been shut off. If the water is off at the main, they can’t run the taps. That’s a known limitation, not a failure on their part.

San Diego Has Its Own Set of Risks

Southern California properties come with some specific concerns that show up in inspection reports more often than you might expect.

Seismic movement is a quiet but constant force here. Even in areas that haven’t seen a major earthquake recently, foundation cracking, uneven floors, and doors that stick or won’t close properly are common findings — all signs of gradual ground movement over time.

Coastal salt air accelerates corrosion on anything metal: plumbing fittings, electrical connections, HVAC components. Homes within a few miles of the coast tend to age differently than inland properties, and a good inspector will look for this.

Older plumbing is another recurring issue. Pipes in homes built before the 1980s are often galvanized steel, which rusts from the inside out. Slow leaks inside walls can go unnoticed for years, leading to mold and structural rot that’s expensive to fix. This is one reason a sewer scope — a camera inspection of the drain line — is strongly recommended for any home built before 1980. It costs $250–$550 and can save you from an $8,000+ surprise.

Wildfire risk affects nearly 17% of homes in San Diego County. Beyond checking for defensible space and fire-resistant materials, inspectors sometimes find evidence of past fire damage — to neighboring structures or the home itself — that wasn’t properly remediated. Worth knowing before you close.

Electrical systems in older homes are often undersized for modern use. Homes wired decades ago weren’t designed for EV chargers, multiple large appliances, and today’s general power demands. An outdated panel isn’t just inconvenient — it’s a fire risk.

Add-On Inspections Worth Considering

A standard inspection is thorough, but it doesn’t cover everything. Depending on the property, your inspector may recommend bringing in specialists for a closer look.

Termite and Wood-Destroying Organism (WDO) inspection — California’s climate is hospitable to termites year-round. These inspections are required for VA loans and are a smart add-on for nearly any property, particularly older homes with wood framing or decks.

Thermal imaging — An infrared camera can detect moisture trapped inside walls, electrical hotspots, and gaps in insulation without opening anything up. It’s especially useful in older homes or properties that have had any water damage history.

SB 721 compliance — If you’re buying a condo or multi-unit property, California law now requires inspection of exterior elevated elements (think balconies and decks) every six years. Make sure this is current before you close.

How the Inspection Fits Into the Bigger Picture

One thing first-time buyers sometimes don’t realize: the inspection report is just one of three documents you’ll be reviewing during escrow. The other two are the Seller Disclosure (the owner’s written account of the home’s history, known issues, and past repairs) and the Agent Visual Inspection Disclosure (your agent’s observations from their walkthrough).

All three documents matter, and they often contain different information. The seller might know about a roof repair from five years ago that the inspector can’t detect now. The inspector might find an issue the seller genuinely wasn’t aware of. Reading them together gives you the most complete picture.

What Happens When Problems Are Found

Finding issues in an inspection report is normal — it doesn’t mean the deal is off. What it means is that you now have documented evidence to work with.

Most buyers use the inspection report to negotiate: requesting a credit toward repairs, asking the seller to fix specific items before closing, or adjusting the purchase price to reflect the work that needs to be done. Reports often include estimated repair costs, which makes these conversations easier to have.

About 75% of contracts in California include an inspection contingency, meaning if the findings are serious enough, you can walk away without losing your deposit. That’s a meaningful protection, and it’s worth making sure yours is in place.

One practical tip: try to attend the final hour or two of your inspection. Walking through with the inspector and seeing issues firsthand — rather than just reading about them in a report — makes a significant difference in how well you understand what you’re buying.

The Bottom Line

A home inspection won’t tell you everything about a property, and it won’t make your decision for you. What it will do is give you a clear, professional assessment of what you’re actually buying — before you’re legally committed to buying it. For most first-time
