A 4-point home inspection is a focused, insurance-driven visit that examines four specific building systems: roof, HVAC, electrical, and plumbing. Florida insurance carriers commonly require this report for homes that are twenty years old or older before they will write or renew a homeowner’s policy. The visit is shorter and cheaper than a full home inspection, the deliverable goes to the insurance carrier rather than the homeowner, and the focus is narrower. This guide walks through what the 4-point inspection covers, how it differs from a full home inspection, and what homeowners should expect from the process.

What a 4-point inspection actually examines

The four points are the four major systems that insurance underwriters care most about because failures in those systems generate the largest claim costs. The roof is the primary weather barrier; a failing roof produces interior water damage that cascades through the home. The HVAC system is expensive to repair and presents fire and carbon-monoxide risks when it fails. The electrical system is the source of most house fires when it fails. The plumbing system is the source of most water damage when it fails. By examining those four systems specifically, an insurance carrier can estimate the risk of writing a policy on the home.

The parent hiring a home inspector guide covers the broader inspection landscape; this guide focuses on the 4-point variant specifically. Sibling guides such as the scope-by-system overview and the real-estate inspection guide place the 4-point in context.

How the 4-point differs from a full home inspection

A full home inspection covers ten or more building systems and produces a detailed report aimed at the homebuyer. The inspector looks at the structure, exterior, interior, insulation, ventilation, appliances, and the four systems already mentioned. The deliverable runs forty to one hundred pages with photographs and detailed narrative observations. The fee runs from three hundred fifty to seven hundred fifty dollars for a typical single-family home depending on location.

A 4-point inspection limits the scope to the four named systems and produces a shorter standardized report that goes to the insurance carrier. The deliverable is usually four to eight pages organized into sections matching the four systems. The fee runs from fifty to one hundred fifty dollars in most markets. The inspector spends roughly one to two hours on site, compared to three to four hours for a full inspection. The homeowner usually does not receive a detailed homeowner-facing narrative because the document is structured for underwriting use.

Why Florida is the dominant market

Florida insurance carriers institutionalized the 4-point inspection during the 1990s as the state’s housing stock aged and weather-related losses mounted. The state’s hurricane exposure, humid climate, and large pool of homes constructed before modern building codes made age-based underwriting an important risk-management tool. Other states have adopted similar requirements for older homes, particularly along the Gulf Coast and in parts of the Southwest, but Florida remains the dominant market by volume.

The twenty-year age threshold is the most common trigger. A 2005-built home will not need a 4-point in most Florida markets until 2025. A 1995-built home already needs one. Some carriers extend the requirement to all homes regardless of age; some restrict it to homes thirty or forty years old. The exact threshold depends on the carrier and the underwriting policy in effect at the time of the request.

What the roof section covers

The roof section of a 4-point report documents the roof’s current condition and estimates the remaining service life. The inspector notes the roof-covering material — asphalt shingles, tile, metal, flat-roof membrane — and the installation date if available. They look for visible damage: lifted shingles, missing pieces, cracked tiles, ponding water on flat roofs, exposed underlayment, deteriorating flashing around vents and chimneys.

The remaining-life estimate matters because most insurance carriers will not write or renew a policy on a home with less than two to three years of remaining roof life. Asphalt-shingle roofs typically last fifteen to twenty-five years; tile roofs last thirty to fifty years; metal roofs last forty to seventy years. The inspector applies professional judgment to estimate how many more years the current roof will perform reliably.

What the HVAC section covers

The HVAC section documents the heating and cooling equipment by type, age, and operational condition. The inspector notes whether the system is electric heat pump, gas furnace with central air conditioning, or a less common configuration. They record the manufacturing dates from the equipment data plates, which lets the carrier estimate remaining service life against the manufacturer’s typical lifespan.

Operational testing during the 4-point visit usually involves running the system through a heating cycle and a cooling cycle while the inspector observes for unusual sounds, leaks, or visible failure indicators. The inspector does not perform refrigerant-charge measurements, ductwork pressure testing, or other deep diagnostic work that an HVAC contractor would perform. The deliverable is a high-level assessment of whether the system is operational and how much service life remains.

What the electrical section covers

The electrical section documents the service entrance configuration, the main panel manufacturer and model, the presence or absence of known-problematic equipment, and the general condition of visible wiring. The inspector records the panel amperage, the wiring material (copper or aluminum branch circuits), the breaker manufacturer (Federal Pacific Stab-Lok and Zinsco panels are typically flagged), and the condition of the service entrance from outside.

Insurance carriers care particularly about three flagged conditions. Federal Pacific Stab-Lok breakers have a documented history of failing to trip under overload conditions and pose fire risks; many carriers refuse to write policies on homes with these panels. Zinsco panels carry similar concerns. Aluminum branch wiring used between 1965 and 1973 has a higher connection-failure rate than copper and may require approved remediation before a carrier writes a policy.

What the plumbing section covers

The plumbing section documents the water-supply piping material, the drain-waste-vent piping material, the water-heater type and age, and the general condition of visible plumbing. The inspector records whether the supply lines are copper, PEX, CPVC, galvanized steel, or polybutylene. They record the drain lines as cast iron, PVC, ABS, or galvanized. They note the water heater’s age, capacity, and condition.

Polybutylene supply piping and Quest fittings installed between roughly 1978 and 1995 are the major flagged plumbing concerns. These systems have a documented history of premature failure that has produced significant claim losses for insurance carriers; many carriers refuse to write policies on homes with active polybutylene plumbing. Galvanized supply piping older than fifty years is also commonly flagged because internal corrosion reduces flow and increases the risk of pinhole leaks.

What the homeowner sees from the visit

The homeowner schedules the inspection, lets the inspector into the home, and pays the inspection fee. The inspector spends one to two hours examining the four systems and may ask the homeowner for documentation: roof installation receipts, HVAC service records, electrical panel upgrade history. The deliverable goes directly to the insurance carrier in most cases. The homeowner may receive a copy of the report on request, but the primary recipient is the underwriter.

If the report identifies issues that affect insurability, the carrier may decline to renew the policy, may require remediation before binding coverage, or may add exclusions to the policy that limit coverage for the flagged systems. Homeowners who receive these contingent decisions usually have a defined window to remediate and resubmit before the policy lapses.

Common findings that affect insurability

Three findings commonly affect insurance binding. The first is a roof with less than two to three years of estimated remaining life. The carrier may require roof replacement before binding or may issue a policy with an actual-cash-value rather than replacement-cost roof endorsement, which is significantly less valuable to the homeowner in a claim. The second is the presence of Federal Pacific Stab-Lok or Zinsco panels. The carrier may require panel replacement before binding. The third is active polybutylene plumbing. The carrier may require partial or full repipe before binding.

Homeowners facing any of these findings benefit from consulting an independent contractor before agreeing to the remediation the carrier suggests. A roofer can confirm whether replacement is genuinely needed or whether a less-expensive repair would extend the life enough to satisfy the carrier. An electrician can evaluate whether a full panel replacement or a partial breaker-swap meets the carrier’s requirements. The 4-point inspector identifies issues but does not specify the remediation; that is the contractor’s role.

Front Range homeowners and similar requirements

Colorado does not have the same widespread 4-point inspection requirement Florida does, but some Front Range carriers — particularly for older homes in central Denver — request similar focused inspections before binding policies. Homeowners in Denver, Boulder, Jefferson, and Adams counties with homes built before 1970 may encounter underwriting requests that resemble the Florida 4-point in scope. A working home inspector in the region can produce a similar deliverable on request, even if the carrier does not use the specific 4-point label.

How a 4-point fits into a real-estate transaction

Buyers purchasing a Florida home twenty years or older often discover the 4-point requirement only when they apply for homeowner’s insurance after going under contract. The insurance application triggers the carrier’s underwriting workflow, which generates the 4-point request, which the buyer or seller has to fulfill before the policy can bind. The contract closing date may depend on the policy binding, which makes the 4-point a time-critical step.

Some real-estate agents recommend completing the 4-point as part of the pre-listing process so the seller can address any findings before the home goes on the market. That approach reduces the risk of a late-stage insurance complication derailing the closing. Other agents wait until the buyer’s loan and insurance applications are in motion, accepting the timing risk in exchange for not paying for an inspection the buyer might re-order anyway.

Buyers should treat the 4-point as a complement to, not a substitute for, the standard pre-purchase home inspection. The standard inspection covers the full house and produces a buyer-facing report; the 4-point covers four systems and produces an underwriter-facing report. Skipping the standard inspection in favor of the 4-point leaves the buyer without the broader picture they need to make purchase decisions, even if the 4-point satisfies the carrier.

Choosing an inspector for the 4-point

Most working home inspectors offer 4-point inspections as a separate service from their full home inspections. The 4-point report uses a standardized form that varies slightly between insurance carriers but follows a common content structure. Inspectors familiar with the specific carrier’s preferred form complete the deliverable more quickly than inspectors who have to look up the form for each visit. Buyers and sellers benefit from asking the inspector whether they have completed 4-points for the requesting carrier before.
