The Ultimate Guide to Passing a Four Point Home Insurance Inspection

Insurers often rely on a four-point inspection to determine if they can even insure your home. If you’ve recently remodeled in California, you’ll probably be given one of these inspections, and yet, homeowners don’t know what prompts it or understand what deficiencies can be found.

What a four-point inspection actually checks

The four points are roofing, electrical, plumbing, and HVAC. That’s it. An inspector walks the property, pulls a panel cover, checks the attic, runs water in a few fixtures, and writes a report that your insurer uses to decide whether to renew your policy, raise your premium, or deny coverage outright.

Insurers don’t request these randomly. In California, they usually get triggered by one of three things: the home is older and coming up for a renewal review, the insurer pulled a CLUE report and saw claims history that concerns them, or – increasingly common – you filed a permit for a renovation and the county or your carrier flagged it. Home renovation underwriting has gotten aggressive over the last few years, and a kitchen remodel or panel upgrade can put your policy back on an underwriter’s desk even if nothing was wrong with it before.

The electrical section is where most homes fail

Electricity is the category that kills more applications than the other three combined, and it’s not even close. Inspectors are checking for three things, and any one of them is a hard no.

One, unsafe breaker brands. Federal Pacific Electric Stab-Lok panels and Zinsco panels are both widely recalled and both an instant denial. These panels and their breakers were used in jaw-dropping quantities for a few decades through the ’60s and ’70s, and the breakers have a long paper trail of failing to trip during an overload – you know, the reason you have a breaker. If your home still has one of these panels, no amount of elbow grease will change the result.

Two, old 60-amp fuse boxes. Anything under 100 amps is treated as all but certain to be denied by most carriers, and honestly, 100 amps is barely enough for a modern household with central air, an electric stove, and a few phone chargers going at once. Most insurance companies want to see 150 amps or more on an updated home, especially if you’ve added any square footage or new appliances.

Third, any visible sign of DIY wiring – exposed splices, missing junction boxes, wire nuts without covers, anything that looks like it wasn’t pulled to code. Inspectors don’t need to prove it was unpermitted. They just need to see it.

If your panel falls into any of these categories, the fix isn’t cosmetic. It’s a full replacement, done by a licensed electrician who pulls the proper permit and signs off on the work. A lot of homeowners in this position end up going with a service like Smartchoice electrical panel installation specifically because insurers want documentation that the job was done by someone licensed, not a handyman doing a favor. This one line item, done right, is usually enough to flip an automatic fail into a clean pass. Electrical distribution equipment was involved in 10% of reported home fires (NFPA), and that risk sits almost entirely with older homes running outdated panels and wiring – which is exactly why insurers treat this section so strictly.

Aluminum branch circuit wiring is a red flag that this is a home built in the 60s and 70s. It’s not always an automatic fail, but they are going to want to see proper connectors (like COPALUM or AlumiConn) at every termination point, not raw aluminum twisted onto a copper-rated device. If that repair hasn’t been done, it’s going on the report.

Modern code also requires kitchen, bathroom, bedroom, and outdoor circuits to be protected by arc-fault circuit interrupters and GFCIs. They will test these. A tripped or dead GFCI outlet is a quick fail for something that costs about ten bucks to fix, so there’s no excuse for leaving one dead before the inspector shows up.

Roofing: age and paperwork both matter

Roof condition and age are used to evaluate whether a roof is insurable or not. In general, most insurers prefer to see asphalt shingle roofs under 20-25 years old, with no visible curling, missing granules, staining, or patch jobs that look improvised. A roof at year 22 with a clean surface might still pass. A roof at year 15 with some obvious wear might not.

Here’s the part most people overlook: if you’ve had roof repairs done, the inspector and the insurer are going to want to see a permit tied to that work. An unpermitted patch job reads as a liability, not a fix, because there’s no paper trail indicating it was handled responsibly. If your roof is anywhere near the upper end of its expected lifespan, a full re-roof is genuinely the fastest way to move your insurability in the right direction. It’s not cheap, but it resolves the entire category in one pass rather than leaving you exposed to guesswork every renewal cycle.

Plumbing: two materials will sink you

Plumbing failures almost always come down to pipe material. Galvanized steel and polybutylene are the two insurers treat as deal-breakers. Galvanized pipe corrodes from the inside out and eventually restricts flow or fails at joints. Polybutylene, common in homes built through the 80s and early 90s, is prone to cracking and was the subject of massive class-action litigation years ago. Neither one gets a pass, no matter how well-maintained it looks on the surface.

Beyond pipe material, inspectors check under every sink and around the water heater for active drips, corrosion at fittings, and missing shut-off valves. In California specifically, they’ll also check for water heater seismic strapping – this is a state-specific code requirement, and an unstrapped tank is an easy, cheap fix that gets overlooked constantly.

HVAC: age plus maintenance records

The age of your HVAC isn’t the only factor when it comes to whether or not the system will be okayed by an inspector. But most are using a simple rule of thumb – if a unit is 15-20 years of age or older, insurers consider them more risky. The same goes for any unit with rust, a corroded condensate pan, or blocked clearance surrounding the unit. Clearances around the unit are more important than most people realize – if the furnace intake or outdoor unit has storage boxed in around it, clear it out before the inspector arrives.

The simplest thing you can use as "evidence" with the inspector is to hand them a dated service invoice showing recent service. It doesn’t prove the unit is new, but it implies that someone looked at it and determined it’s in good working order.

Seven California renovations that should trigger your own insurance review

Do not let your insurer find you instead. Be proactive if you have done any of the following:

Kitchen remodel: New wiring circuits, new appliances that use more amperage, sometimes a relocated gas line – all things that can show up under electrical or plumbing at the same time.

Bathroom remodel: Re-piping, new GFCI circuits, and ventilation changes are all items that show up on a four-point.

Electrical panel upgrade: Oddly enough, even a good-faith upgrade can have your file reviewed if that permit wasn’t closed out properly with the local building department.

Roof replacement: This resets the Roof Age in the file which is generally good news, but only if the permit is on record.

Re-piping: The removal of galvanized or polybutylene in favor of PEX or copper is a big insurability win, but not until it’s on paper.

HVAC replacement: A new system resets the age-based fail threshold.

Square-footage additions: New rooms are new electrical load, new plumbing runs, and often a full re-underwriting of the policy as the dwelling coverage amount has to change anyway.

Any one of these can bring your policy back under review under Title 24 energy code requirements or general code compliance checks, especially if the local jurisdiction is sharing permit data with the carriers, which more counties in California now do.

Pull your permits before you schedule anything

The most important advice in this guide is that if permits don’t cover your upgrade, insurance carriers must assume the worst. An unpermitted upgrade is a liability in their eyes. The underwriters have to base their decision on data that can be documented and verified. That means permits. There’s no guarantee from the California Department of Insurance about what conditions must pass inspection, but there is a guarantee that insurers must decide based on provable details. And the permits are your paper trail. They’re what an insurance company uses to determine whether or not your upgrades count.

So, spend some time before you arrange your four-point inspection gathering every single permit you have from work over the previous five to ten years. If something slipped through the cracks, look into getting it finalized by your local building department or prepare to have it reinspected.

The pre-inspection sweep

A brief tour the week before your inspection nips most easily avoidable failures in the bud:

Replace any dead or tripped GFCI outlets. Test every arc-fault breaker in the panel by hitting the test button – if it doesn’t trip, it needs replacement. Leave at least two feet of clearance around HVAC units. Check that your water heater has proper seismic strapping. Look under every sink for slow drips or corrosion at the shut-off valve.

None of this fixes a recalled panel or a 25-year-old roof, but it clears out the small stuff that turns an otherwise passable inspection into a denial over something trivial.

There’s no negotiating a real failure

Insurance companies do not compromise on such matters. An FPE panel must be replaced without exceptions. Similarly, a roof that is 27 years old must be entirely replaced. When it comes to polybutylene plumbing, it must be entirely re-piped. A letter stating that the panel "appears to be in good condition" or that the roof "does not appear to be leaking" is unacceptable. The report is very clear in these cases, and the only solution to correct a failed item is to go ahead with the replacement and provide the documentation.

What passing actually gets you

Passing an inspection ensures a lot more than ticking a box. You’ll likely have a lower premium because you have eliminated the systems that insurers base their risk assessment on the most. Your policy will not exclude coverage for older electrical or plumbing systems, which often happens when borderline homes are approved with conditions. And your actual fire and water-loss risk is reduced, not just on paper.

Renovations are meant to improve your home. Consider the insurance review as part of the renovation, rather than as an after-the-fact issue, and you’ll end up with a home that is truly safer and an insurance policy that reflects that.
