4-Point Inspections

California 4-Point Inspection: What It Is and When Insurers Require One

A 4-point inspection is a focused report on a home's roof, electrical, plumbing, and HVAC systems — the four most expensive systems insurers worry about. California carriers increasingly require one for older homes (typically 20+ years) before binding or renewing coverage.

Book a 4-Point Inspection

If your carrier sent a letter asking for a "4-point" before they would bind or renew, you're not alone. The same form that has been standard in Florida for years is now arriving in California mailboxes, driven by a wave of non-renewals on older homes after years of catastrophic wildfire losses. This guide walks through exactly what gets inspected, what triggers insurer concern, when you'll be asked for the report, what it costs, and how the 4-point differs from a full home inspection.

The short version: A 4-point inspection takes 45–90 minutes, costs $175 flat in Santa Barbara County, and documents the age and condition of your roof, electrical, plumbing, and HVAC. Insurers use it to decide whether to write or renew your policy. It is not a home inspection — the foundation, drainage, structure, and dozens of other systems are out of scope.

What the four points actually are

Each "point" is one major system. For each, an inspector documents age, materials, observed condition, and any safety or functional defects on the carrier's form. The reason these four were chosen is straightforward: they are the systems whose failure produces the largest insurance claims. A roof failure becomes interior water damage and mold. An electrical failure becomes a structure fire. A plumbing failure becomes flooded floors and drywall. An HVAC failure becomes carbon-monoxide exposure or a refrigerant leak. Underwriters have a century of loss data telling them where the money goes, and these are the systems on that list.

Here is what we look at for each, and the findings that consistently trigger underwriter pushback.

1Roof

What inspectors check

  • Covering type (asphalt, tile, metal, foam, wood) and age
  • Remaining useful life estimate
  • Visible damage: cracked tiles, curled shingles, granular loss, ponding
  • Flashing, valleys, penetrations, and underlayment where visible
  • Active or past leak evidence in the attic or ceilings

Red flags for insurers

  • Asphalt shingles past 15–20 years
  • Tile roofs with failed underlayment ("lift & relay" territory)
  • Less than 3–5 years of remaining useful life
  • Active leaks or significant prior repairs

2Electrical

What inspectors check

  • Panel brand, age, amperage, and dead-front condition
  • Branch wiring type (copper, aluminum, knob-and-tube)
  • Double-tapped breakers, missing knockouts, exposed splices
  • GFCI and AFCI protection where required
  • Grounding and bonding of the service

Red flags for insurers

See our electrical panel service →

3Plumbing

What inspectors check

  • Supply piping material (copper, PEX, galvanized, polybutylene)
  • Drain piping material (ABS, PVC, cast iron, Orangeburg)
  • Water heater age, type, and TPR/seismic strapping
  • Active leaks, corrosion, and prior repairs
  • Main shut-off location and function

Red flags for insurers

  • Polybutylene supply lines — rupture-prone, often non-insurable
  • Galvanized supply piping over ~40 years old
  • Water heater over 12–15 years or unstrapped
  • Active drips, staining, or visible corrosion
See our plumbing inspection →

4HVAC

What inspectors check

  • Equipment type, age, and manufacturer data
  • Cooling and heating operation at the thermostat
  • Condition of supply and return ducts where visible
  • Combustion air, venting, and flue condition (gas)
  • Condensate handling and visible refrigerant lines

Red flags for insurers

  • Furnace or AC over 15–20 years old
  • System non-functional at time of inspection
  • Improper venting or rusted heat exchanger evidence
  • Heavy water staining at the air handler

Why California is adopting 4-Points

The 4-point form was perfected in Florida, where hurricane-driven losses pushed carriers to demand documentation on older homes before they would write coverage. For decades, California sat on the other side of that line — a stable, profitable market where homeowner policies renewed automatically. That has changed.

After consecutive years of catastrophic wildfire losses, several of the largest national carriers paused new-business writing in California, and others stopped renewing tens of thousands of existing policies. The California FAIR Plan — the insurer of last resort — has absorbed the overflow and is now the largest writer of homeowners coverage in several high-risk ZIP codes. The carriers that remain in the market have responded the way Florida insurers did: by demanding proof of condition before they will bind or renew.

For older California homes, that proof increasingly takes the shape of a 4-point inspection. Pre-1990 builds, homes with original roofs, and any house with a flagged panel brand are the most likely to be asked. Even newer homes in wildfire-exposed canyons are seeing requests when a carrier switches, a claim is filed, or the property moves onto the FAIR Plan. If you want the deeper read on why carriers are pulling back, our California insurance inspections guide covers the broader picture.

The practical effect for homeowners: the inspection has moved from optional to required. Five years ago, the only Californians asking for 4-points were buyers moving here from Florida who already knew the form. Today, the requests come from local underwriters writing local risks, on local forms. The Santa Barbara County housing stock — large segments built in the 1950s, 1960s and 1970s, with original panels, original underlayment, and original galvanized supply lines — sits squarely in the age range carriers are now scrutinizing. A 4-point is the document that translates "the house is fine" from a feeling into a record an underwriter can file.

When you'll be asked for one

You will rarely be asked for a 4-point out of the blue. The request almost always follows one of these triggers:

TriggerTypical thresholdWhat the carrier does
Home age20–30+ yearsRequests 4-point at new-business binding or renewal
Roof ageRoof 15+ years (asphalt) or 25+ years (tile)Requests roof condition report or full 4-point
Recent claim1+ claim in the last 3–5 yearsRequires 4-point before renewal decision
FAIR Plan issuanceAny older home placing onto the FAIR PlanTypically requires 4-point and roof verification
Carrier switchingAfter a non-renewal or shopping for new coverageNew carrier requires 4-point before binding
Purchase in escrowBuying an older home; lender requires bound coverageRequired before close so a policy can be written

If you received a letter, look for the phrase "4-point inspection" or "verification of the roof, electrical, plumbing and HVAC." That's what they want. Some carriers send their own preferred form — we complete the inspection on that form so it can be submitted directly.

One thing to watch: deadlines on these letters are short. Carriers typically give 30 to 60 days from the date of the letter, and a missed deadline can convert a request into a non-renewal. If you've been sitting on a request because you weren't sure what it meant, the first move is to call your agent and ask which inspection they actually want. The second is to book it. The third is to send the report in before the deadline, on the form the carrier provided.

What insurers are looking for (red flags)

The 4-point report is condition documentation, but every line item maps to a specific underwriting concern. These are the findings that most often change a binding decision:

SystemRed flagLikely insurer response
RoofAsphalt shingle 15+ years oldReplacement required before binding or non-renewal
RoofTile roof with failed underlaymentLift-and-relay or full replacement required
ElectricalFederal Pacific Stab-LokNon-insurable until replaced
ElectricalZinsco / Sylvania-ZinscoNon-insurable until replaced
ElectricalKnob-and-tube or aluminum branch wiringCoverage often denied or requires remediation
Electrical60-amp service or fuse boxService upgrade typically required
PlumbingPolybutylene supply linesRepipe required before binding
PlumbingGalvanized supply piping, 40+ yearsRepipe or higher premium / exclusions
PlumbingWater heater 15+ years, unstrappedReplacement and strapping required
HVACFurnace or AC 15+ yearsInspection often allowed; replacement sometimes required
HVACNon-operational at time of inspectionRepair required and re-inspection

None of these are deal-breakers for a homeowner — they are signals. A replacement, repair, or repipe brings the home back into insurable shape, and a follow-up inspection documents the fix. Where it gets uncomfortable is when several of these stack up on one property: a 30-year-old asphalt roof and a Federal Pacific panel and galvanized supply lines. At that point underwriters tend to walk, and the FAIR Plan often becomes the only path to coverage until upgrades are made.

If the 4-point flags an issue you didn't know about, that's actually the point of the report. Insurers reward documented upgrades: replace a flagged panel, hand the inspector your permit and final, and the next report comes back clean. We frequently re-inspect the same home a few months after a repipe or roof replacement so the homeowner can submit an updated 4-point to their carrier and clear the file.

4-Point vs full home inspection

Buyers in escrow ask us this constantly. The two reports are not interchangeable; they exist for different audiences and have different scopes.

If you're buying an older home in escrow, you may need both: a full inspection for your own due diligence, and a 4-point so the lender's required policy can bind. We routinely bundle the two on the same site visit.

Two practical points buyers and sellers ask about. First, a full home inspection report is not a substitute for a 4-point. Even if the home inspection covers all four systems in detail, it doesn't sit on the carrier's required form — and underwriters reject reports that aren't on their form. Second, the 4-point form is filled out by the inspector at the time of inspection; we do not "translate" a recent home-inspection report into a 4-point after the fact. Both reports require a fresh on-site visit, though we can complete them on the same trip and keep the total cost low.

What it costs in California

$175 flat, Santa Barbara County

Includes the on-site inspection, completion of the carrier's 4-point form, and digital delivery so you can forward it to your agent or underwriter directly.

Book at $175

Across California, 4-point inspections typically run $150 to $300. Pricing varies by region, square footage, and whether the inspector bundles the report with additional documentation — a roof condition report, an electrical panel verification, or a wildfire-mitigation report can be added at the same visit. Some firms charge by square footage; we keep ours flat so there are no surprises. See full pricing on our pricing page.

If your home is on the FAIR Plan or being placed onto it, expect the carrier to request 4-point and a separate roof condition report at minimum. We can complete both at the same visit so you're not paying two trip fees.

A note on what not to pay for: some companies advertise 4-points at very low prices and then upsell additional reports, photos, or "expedited" delivery. A complete 4-point should include the carrier's full form, dated and signed by a qualified inspector, with photos of the panel, roof, water heater, and HVAC condenser. That's the deliverable that gets accepted by underwriting. Anything less typically comes back from the carrier with a request for more documentation, which means a second visit and another fee.

Common questions

California 4-point inspections, answered.

What is a 4-point inspection?
A 4-point inspection is a focused report on a home's four major systems — roof, electrical, plumbing and HVAC — written specifically for insurance underwriting. It documents the age and condition of each system so a carrier can decide whether to bind or renew a policy. It is narrower than a full home inspection and is the standard report insurers request on older homes.
How much does a 4-point inspection cost in California?
In Santa Barbara County, Coastal Shield charges a flat $175 for a 4-point inspection. Across California, prices typically run between $150 and $300 depending on the inspector, square footage, and whether the report is bundled with other insurance documentation.
Is a 4-point inspection the same as a home inspection?
No. A 4-point inspection only evaluates four systems — roof, electrical, plumbing and HVAC — for an insurance carrier. A full home inspection is much broader and covers foundation, structure, drainage, exterior, appliances, attic, crawl space and dozens of other items for a buyer's due diligence. They serve different audiences and aren't interchangeable.
How long does a 4-point inspection take?
Most 4-point inspections take 45 to 90 minutes on-site, plus a short time afterward to complete the carrier's form. Larger or more complex homes can take longer, especially if the panel cover needs to be pulled or attic access is involved.
Who orders a 4-point inspection — the buyer or the homeowner?
Either, depending on the situation. A buyer may order one during escrow if the lender or carrier requires it to bind a new policy. An existing homeowner usually orders one after receiving an inspection demand letter, a renewal questionnaire, or a non-renewal notice from their carrier.
Does a 4-point inspection include the foundation?
No. A 4-point inspection is limited to roof, electrical, plumbing and HVAC. It does not evaluate the foundation, structure, drainage, grading or any other system. If you want foundation and structural review you need a full home inspection.
Will my insurance require a 4-point inspection if I have a Federal Pacific panel?
Almost certainly yes — and the 4-point will flag it. Federal Pacific Stab-Lok and Zinsco panels are routinely uninsurable in California because their breakers can fail to trip on overload. Most carriers require these panels to be replaced before they will write or renew a policy, regardless of the home's age. See our Federal Pacific guide and Zinsco guide for what replacement looks like.
How long is a 4-point inspection valid?
Most California carriers treat a 4-point inspection as valid for 12 months, though some accept reports up to 24 months old. If material changes occur — a new roof, a panel replacement, a re-pipe — many insurers will want an updated report to reflect the upgrade.
Do I need a 4-point inspection if my house is new?
Usually no. Carriers reserve 4-point inspections for older homes, typically those 20 to 30+ years old, because the four systems are the ones that age and fail. Homes under about 20 years generally bind on the standard application alone.
Can a 4-point inspection fail?
A 4-point inspection isn't pass/fail in the strict sense — it's a condition report. But carriers can reject the home based on what's in it: an aged roof, a hazard-flagged panel, polybutylene plumbing, or an end-of-life HVAC system can all trigger a refusal to bind, a requirement to repair, or a non-renewal.
