How to Use Building Permit History on an Insurance Claim

Ask a carrier why a roof claim was underpaid and the answer is often one word: age. The older the carrier says the roof is, the more it depreciates, and the easier it is to call the damage wear and tear.

The fastest way to answer that argument is a document most adjusters never pull: the property’s building permit history. This guide explains what permit records contain, the four ways they strengthen a claim, and how to get them for any address.

What is building permit history?

Every time a property owner or contractor pulls a building permit, the local jurisdiction creates a record. Over the life of a property, those records add up to a timeline of the work done on it: re-roofs, additions, pools, HVAC, electrical, plumbing, solar, windows and doors, and general building work.

A permit record typically shows:

• The permit type, number, status, jurisdiction, and description
• Its dates: filed, issued, started, finaled, and expiration
• The job value and permit fees, where reported
• Inspection results on the permit
• The contractor and applicant on record

Four ways permit history strengthens a claim

1. Prove the roof’s real age

Carriers depreciate a roof based on its age, and when they do not know it, they often assume the roof is as old as the house. A re-roof permit shows when the roof was actually replaced. If a 1950s house got a new roof six years ago, the depreciation should reflect a six-year-old roof, not a seventy-year-old one.

2. Answer "pre-existing damage" arguments

A recent, finaled roofing permit with passed inspections is strong evidence that the roof was in good condition before the storm. Pair it with historical aerial imagery from the same period and you can show the new roof going on, and the roof intact before the loss.

3. Confirm what was built, and when

Additions, pools, and electrical or plumbing work on record explain what is on the property today and when it was added. That matters when a carrier questions a structure, a square footage, or whether a system was original to the house.

4. Plan for code upgrades

When damaged parts of a building are repaired, current building codes can require upgrades that go beyond the original construction. Knowing when the roof and major systems were last permitted helps you spot those upgrades early and review the policy’s ordinance or law coverage. Dex can find the exact ordinance or law language in the policy for you.

A real example

Drodat’s demo property in Surfside, Florida has 22 permits on record. Among them:

• A residential re-roof permit for a metal roof, issued December 7, 2020
• A residential pool permit, issued April 25, 2022, with the matching pool electrical and plumbing permits issued July 28, 2022
• A residential addition application from 2023

On a roof claim for this property, the re-roof permit shows the roof was about five years old in 2026, not original to the house. Step through the property’s aerial captures and you can see the change for yourself: a different roof in earlier years, and the metal roof after 2020.

How to get permit history for a property

You can request permit records from the local building department, but it can take days, and every jurisdiction works differently. In Drodat, permit history is already on the property:

1. Open the property. The Permits tab lists every permit on record for the address, newest first, with a total count.
2. Filter by category. Narrow the list to roofing, HVAC, electrical, plumbing, solar, EV chargers, pools and hot tubs, windows and doors, additions, or general building work.
3. Open a permit. See its dates, job value, fees, inspection results, and the contractor and applicant on record. The property’s facts, such as year built, building area, lot size, stories, and assessed value, are there too.
4. Share the record. Download one permit or all of them. Each permit PDF carries a QR code that links to a public verification page, so the carrier can check it.

What if a property shows no permits?

It means no permits were found in the data for that address. Some jurisdictions keep records that are not published, so the local building department may have more. A missing permit is not proof that work was never done, and it is worth asking the owner for receipts or contracts from any past roof work.

Put it next to the rest of the evidence

Permit history is strongest alongside the rest of the property record. In Drodat, the same property shows its weather history for the date of loss, its historical aerial imagery, and its roof measurements, all in one place.
