A 4-point inspection for home insurance is a short report on a home’s roof, electrical, plumbing, and HVAC that a carrier uses to decide whether to write or renew a policy. San Diego insurers commonly require one on homes roughly 25 to 40 years old, because those four systems drive most large claims. It is an underwriting document, not a buyer’s inspection.
Why Home Insurers Ask for a 4-Point in San Diego
When you apply for a homeowner’s policy, the carrier is pricing risk it cannot see. On a newer home the build standard is known and predictable. On an older home, the carrier has no idea whether the roof is on its third layer, whether the panel is a recalled fire hazard, or whether the supply lines are corroding shut behind the drywall. Rather than guess, the underwriter orders a 4-point inspection and lets the report answer the question.
The four systems are not chosen at random. They are the systems that produce the most expensive insurance claims: fire from failing wiring, water damage from old plumbing, and roof failure during a storm. An HVAC failure is less catastrophic but signals deferred maintenance. If those four are serviceable, the home is a reasonable risk. If one is at the end of its life, the carrier wants to know before it is on the hook.
This collides with San Diego County’s housing stock. We have deep inventory from the 1950s through the 1980s across Clairemont, Allied Gardens, La Mesa, El Cajon, and much of East County, plus older coastal homes in Encinitas, Oceanside, and the beach communities. As those homes cross insurer age thresholds, the 4-point requirement becomes routine, and the California insurance market makes it stricter every year.
The California Insurance Market Makes This Stricter
Over the past few years several major carriers have pulled back from California or tightened underwriting, largely over wildfire exposure. That pressure spills into ordinary homeowner policies. Carriers that remain are pickier about what they will insure, and an aging roof or an obsolete electrical panel is an easy reason to decline or to demand an upgrade first. A clean 4-point inspection has gone from a formality to the thing that actually gets your binder approved.
It also matters at renewal. A carrier can request a fresh 4-point on an older property at renewal time, or non-renew a policy and force you to shop. When you shop, the new carrier almost always wants its own assessment. So a 4-point is not strictly a one-time, point-of-sale event; it can resurface across the life of owning an older San Diego home.
What the Underwriter Is Actually Reading
A 4-point report is concise on purpose. For each system it states the type, the approximate age, the current condition, and any active deficiencies, usually backed by photos. Here is what an underwriter is scanning for in each category.
- Roof – covering type, approximate age, and estimated remaining service life. This is the single biggest factor. Many carriers will not write a policy on a roof with only a few years left, and tile, asphalt, and foam each age differently in our climate. Our guide to San Diego roof types explains what affects that lifespan.
- Electrical – panel brand and amperage, wiring type, and known hazards. Federal Pacific and Zinsco panels are frequent deal-killers. The full picture is in our piece on electrical panel problems in older San Diego homes.
- Plumbing – supply and drain materials, water heater age, and any active leaks or corrosion. Galvanized steel and polybutylene supply lines raise flags.
- HVAC – heating and cooling type, age, and whether the system runs. Inland heat in El Cajon, Santee, and Escondido ages these systems faster, and a dead or absent system is noted.
Vague answers get binders rejected. The underwriter wants the panel manufacturer, the actual amperage, the pipe material, and a remaining-life estimate on the roof. The value of a careful inspector is giving the carrier exactly what it needs the first time, so the policy is not held up over a follow-up question.
What Happens If a System Gets Flagged
A poor finding does not automatically end your application, but it usually means a decision. Depending on the carrier and the severity, you may see one of a few outcomes: coverage declined until the system is replaced, coverage offered with conditions or a surcharge, or a request for documentation that the issue was repaired by a licensed contractor. The roof is the most common sticking point, with the electrical panel close behind.
If you are still in escrow, a flagged system becomes leverage. You can ask the seller to replace the panel or re-roof before close, negotiate a credit, or line up your own contractor with a clear scope. Repair costs vary widely by scope, materials, access, and contractor, so get multiple bids from CSLB-verified licensed contractors before you commit to a number. Knowing the problem before closing is far better than discovering it when your insurer says no.
Keep in mind a 4-point is a visual, non-invasive inspection. We report what is visible and accessible. If a finding points to something specialized – an electrical concern that needs a licensed electrician, suspected pest damage that needs a licensed pest control operator, or a structural question for an engineer – we will tell you to bring in the right pro rather than guess.
A 4-Point Is Not a Buyer’s Inspection
This is the most common and costly mix-up, so it is worth stating plainly. A 4-point inspection serves the insurance company and looks at four systems. A full home inspection serves you and looks at the whole house: foundation, structure, grading and drainage, windows, doors, attic, insulation, appliances, and safety items, in addition to those same four systems in far more depth.
If you are buying an older home that needs a 4-point for your policy, you almost certainly still want a full buyer’s inspection too. The 4-point will not tell you about a cracked slab, poor drainage, or a failing foundation. We can perform both in a single visit, which is usually more efficient than scheduling a standalone 4-point later. For a breakdown of standalone pricing factors, see our 4-point inspection cost guide.
