What a home inspection does and does not cover

A general home inspection is one of the most useful tools a buyer has. It is a few hours with a licensed professional who walks the property and tells you, in writing, the condition of what they can see. It gives you real information before you commit. But it has limits, and knowing those limits up front is what keeps a good inspection from turning into a false sense of security.

Here is what a general inspection covers, what it does not, and how to decide whether you need more.

What a general inspection looks at

A general home inspector evaluates the major systems and components of the home that are visible and accessible on the day they visit. That typically includes:

• The roof, from the ground or the surface where it can be safely reached, noting age, wear, and obvious problems.
• The foundation and structure, in the areas they can actually see, such as an accessible crawl space or basement.
• Plumbing, including visible pipes, water pressure, drainage, and the water heater.
• Electrical, including the panel, visible wiring, outlets, and basic safety items.
• Heating and cooling systems, confirming they turn on and run.
• Interior items like walls, floors, windows, doors, and signs of past water intrusion.
• Exterior items like siding, grading, drainage, and walkways.

The report you get back is detailed and usually has photos. A good inspector explains what is normal wear for the home’s age and what deserves a closer look. That distinction matters, because no older home is perfect, and the goal is understanding, not alarm.

What it does not cover

This is the part buyers most need to hear clearly. A general inspection is visual and non-invasive. The inspector does not open up walls, dig up the yard, or take systems apart. So a few things fall outside the scope by design:

• Anything behind walls or under floors. Hidden wiring, pipes inside a wall, or insulation are not part of a visual inspection.
• The sewer lateral. This is the underground pipe that carries waste from the house to the city main. It needs its own camera scope, and in older Bay Area neighborhoods it is one of the more important specialized inspections you can order.
• The chimney and fireplace interior, which a chimney specialist evaluates with their own equipment.
• Pools and spas, which usually call for a dedicated pool inspector.
• Foundation and structural questions that go beyond what is visible. If the general inspector sees something concerning, the right next step is often a structural or foundation engineer.

A general inspector who spots a possible issue will say so and recommend a specialist. That is exactly how the process is supposed to work. The general inspection is the wide-angle view, and the specialists are the zoom lens.

How to decide which extra inspections to order

You do not need every specialized inspection on every home. Here is how I help buyers decide:

• Start with the general inspection and the disclosures. Read them together. The seller’s disclosure package and the general report usually point you toward what deserves a second opinion. If you want a sense of what a well-organized package looks like, I wrote about what a clean disclosure package actually looks like.
• Let the home’s age and type guide you. An older home in a neighborhood known for original clay sewer lines is a strong candidate for a sewer scope. A home with a pool calls for a pool inspection. A home with a wood-burning fireplace may warrant a chimney check.
• Follow the red flags. If the general inspector flags the foundation, bring in the engineer. If the pest report notes activity, dig into it. Let the findings drive the spending.

Specialized inspections cost money and time, so the goal is to order the ones that actually answer a question you have about this specific property. That keeps your investigation focused and your budget sensible.

The whole point of inspections is to replace worry with information. You go in knowing the home, not guessing about it. If you are getting close to making an offer and want help thinking through which inspections make sense for a particular property, reach out anytime. I am glad to help you build the right short list.
