Four Point Home Inspection: What It Is and When You Need One

You are trying to get homeowners insurance on a house that is 30 years old, and your insurer is requiring a "four point inspection" before they will issue a policy. Or your buyer's agent mentions it during negotiations on a 1985 home in Florida. You have never heard the term, and nobody is explaining exactly what it means.

Here is what it is, why insurers require it, and what will and will not pass.

What Is a Four Point Inspection?

A four point home inspection is a limited scope inspection that covers only four systems of the home:

1. Roofing
2. Electrical
3. Plumbing
4. HVAC (heating, ventilation, and air conditioning)

It does not cover the structural components, foundation, interior finishes, windows, insulation, grading, drainage, or any of the other items a standard buyer's inspection would assess. It is not a comprehensive property condition report — it is a risk assessment for the insurer's four highest-exposure categories.

The format is typically a standardized form (many Florida insurers use a specific Citizens Property Insurance form) that the inspector fills out with the age, condition, and material type for each of the four systems. The inspector also takes photographs of each system, particularly the electrical panel, water heater, and roof.

Why Do Insurers Require It?

Homeowners insurance losses are dominated by four categories: roof claims (storm, wind, hail, age), water damage (plumbing failures), fire (electrical faults), and HVAC-related moisture issues. For older homes, these systems are more likely to be at end of life, made of materials with known failure rates, or installed under outdated codes.

By requiring a four point inspection, the insurer is essentially asking: "Are we about to write a policy on a house that is likely to generate a major claim in the next few years?"

Florida is the most common market for this requirement because of the combination of hurricane exposure, aging housing stock, and an insurance market that has seen catastrophic losses. Most Florida insurers require a four point inspection for homes 25 years or older, and sometimes for homes as young as 15 years. In Louisiana, Alabama, and other Gulf Coast states, similar requirements exist.

Outside of the Southeast US, four point inspections are less common but can still be required for older homes when an insurer perceives elevated risk.

What Each Section Covers

Roof

The inspector documents the type of roof covering (asphalt shingles, tile, metal, flat/modified bitumen), the estimated age, the estimated remaining useful life, and the condition. They look for missing or damaged shingles, granule loss in the gutters, lifted or curling shingles, exposed underlayment, and evidence of prior repairs.

For insurance purposes, the key question is: how many years of life does this roof have left? A roof with less than three to five years of estimated remaining life will often result in the insurer refusing coverage or excluding wind/hail coverage until the roof is replaced.

A secondary concern is roof covering type. Some insurers in high-wind zones will not cover flat or low-slope roofs with modified bitumen membrane unless it has been recently replaced. Metal roofing tends to be viewed favorably for longevity.

Electrical

The electrical section is where four point inspections most commonly result in coverage refusals. The inspector documents:

• The service capacity (100-amp versus 200-amp main service)
• The panel brand and type
• The wiring type (copper, aluminum, knob-and-tube)
• The presence of any double-tapped breakers, improper modifications, or open knockouts

Federal Pacific Stab-Lok panels are an automatic red flag with nearly every insurer. Citizens Property Insurance in Florida explicitly lists them as an unacceptable risk. If the inspector identifies an FPE or Zinsco panel, the insurer will typically decline coverage until the panel is replaced ($2,500-$4,500).

Aluminum wiring in branch circuits (the 15-amp and 20-amp circuits serving outlets and lights, as opposed to the larger aluminum conductors used for main service entrances, which are standard) triggers similar concerns. Branch circuit aluminum wiring was used in homes built from approximately 1965 to 1973. Insurers may require either full rewiring or certified remediation with AlumiConn connectors.

Knob-and-tube wiring in active use typically results in a coverage refusal until the system is updated.

100-amp service may result in a surcharge or denial for homes with central air conditioning, electric ranges, or electric dryers, which the smaller service panel may not adequately support.

Plumbing

The plumbing section documents the water supply pipe material (copper, CPVC, PVC, galvanized steel, polybutylene), the waste/drain pipe material (PVC, cast iron, ABS), the water heater age and condition, and any visible signs of leaks or active water damage.

The single most significant plumbing issue in four point inspections is polybutylene piping. Polybutylene (often grey plastic pipe, with "PB" stamped on it) was used in residential construction from approximately 1978 to 1995 and is notorious for internal degradation from chlorine in municipal water supplies. Most major insurers will not write a policy on a home with active polybutylene supply lines, or they will add a significant exclusion.

Galvanized steel typically results in a notation about age and remaining life rather than an immediate refusal, but an inspector finding corroded or restricted galvanized pipes will document that the system is at or near end of life.

Water heater age matters: most insurers flag water heaters older than 15-20 years as an elevated risk.

HVAC

The HVAC section documents the heating and cooling system types, fuel source (gas, electric, heat pump), equipment ages, and general condition. The inspector will look at the data plates on the furnace, air handler, and condenser unit to determine manufacture dates.

A system older than 15-20 years is typically flagged as near end of life. If the condenser unit still uses R-22 refrigerant (phased out of production as of 2020), that is also noted — it indicates a system that cannot be serviced when it eventually needs a refrigerant charge.

The inspector checks for visible rust, water staining around the air handler (indicating past condensate overflow or leak), and proper flue connections on gas systems.

What Passes and What Does Not

Items that almost always result in coverage refusal or required repairs before a policy is issued:

• Federal Pacific Stab-Lok or Zinsco electrical panels
• Active polybutylene supply piping
• Active knob-and-tube wiring
• A roof with zero to three years of estimated remaining life
• Evidence of active water intrusion or structural roof failure

Items that may result in conditions, exclusions, or higher premiums but not automatic refusal:

• 100-amp service panels
• Galvanized steel plumbing at end of life
• Water heaters older than 15-20 years
• HVAC systems older than 15-20 years
• Roofing with five to eight years of remaining life
• Aluminum branch circuit wiring (depends on insurer and remediation status)

How a Four Point Differs From a Standard Inspection

A standard buyer's inspection covers 12-15 systems and typically runs two to three hours for an average house. A four point inspection covers only four systems and typically takes 45 minutes to an hour.

The purpose is different. A buyer's inspection is about the buyer understanding the full condition of the property so they can negotiate and plan. A four point inspection is about the insurer assessing their specific financial exposure.

You should not substitute a four point inspection for a standard buyer's inspection when purchasing a home. They answer different questions. The four point inspection will not tell you whether the foundation has horizontal cracks, whether the sewer line is failing, whether the attic has adequate insulation, or whether the basement has active moisture infiltration. These are the findings that affect your actual ownership experience and your negotiation position — and they are invisible to the four point format.

Who Can Perform a Four Point Inspection

In Florida, the Citizens Property Insurance four point form requires the inspector to be a licensed home inspector, general contractor, building contractor, or HVAC, plumbing, or electrical contractor (for their specific systems). In most markets, a licensed home inspector can perform a four point inspection.

Cost typically runs $75 to $150 separately, or it may be bundled with a full buyer's inspection at a reduced combined rate. Ask your home inspector whether they offer a bundled price if you need both.

Preparing Your Home for a Four Point Inspection

If you are a seller and you know a buyer's insurer will require a four point inspection, address these before listing or before the inspection is scheduled:

Replace the electrical panel if it is Federal Pacific, Zinsco, or Challenger. This is a sale-enabling repair, not optional. Replace the water heater if it is over 15 years old — it will be flagged regardless, and a new unit gives buyers immediate insurance approval. Get a roofer's assessment and remaining-life estimate so you know before the inspection what condition it is in.

For buyers, the Home Inspection Checklist covers the electrical panel identification section in detail — including photographs and descriptions of FPE and Zinsco panel characteristics — so you can identify potential insurance issues before the inspection appointment and prepare your questions for the inspector.

The Bottom Line

A four point inspection is a focused, limited-scope assessment for insurance underwriting purposes. It covers roof, electrical, plumbing, and HVAC. It tells you whether the insurer will write the policy and on what terms — it does not tell you the full condition of the home.

If your insurer requires one, budget $75 to $150 and about an hour. If you are buying an older home and want the complete picture that a four point inspection cannot provide, that is what a standard pre-purchase inspection is for.
