Florida has some of the strictest building codes in the country — a direct result of Hurricane Andrew's 1992 devastation, which exposed catastrophic failures in pre-storm construction standards. The 2002 Florida Building Code and its subsequent revisions have progressively raised the bar for wind resistance, roofing systems, and structural requirements. For older properties, this creates a significant gap between how they were built and what current code requires. When a hurricane forces a major repair or partial rebuild, that gap becomes a financial exposure — unless you have ordinance or law coverage to close it.
What Ordinance or Law Coverage Does
A standard property insurance policy promises to restore your building to its pre-loss condition. If your 1985 roof is destroyed in a hurricane, the policy pays to replace it with a comparable 1985-era roof system. But building codes don't allow that — the new roof must meet current code requirements, which are significantly more demanding than 1985 standards in Florida.
The cost difference between a code-compliant 2026 roof and a 1985-era replacement roof is your out-of-pocket exposure if you don't have ordinance or law coverage. On a larger or older building, that gap can reach tens of thousands of dollars.
Ordinance or law coverage — sometimes called "Building Ordinance" or "Building Code Upgrade" coverage — fills this gap by paying for the additional cost required to comply with current building codes following a covered loss.
The Three Parts of Ordinance or Law Coverage
Ordinance or law coverage has three distinct components. All three are necessary for complete protection:
Part A — Loss to Undamaged Portion
When building codes require demolishing an undamaged portion of a structure to comply with current standards, Part A pays for the loss in value of that undamaged portion. Example: a building is 60% destroyed by hurricane wind. Local code requires demolishing the remaining 40% because the structure cannot be partially rebuilt to code — it must be torn down entirely and rebuilt. Without Part A, the standard policy only pays for the 60% that was directly damaged; the value of the demolished 40% is uncompensated.
Part B — Demolition Cost
Part B pays the actual cost to demolish the undamaged portion that must be torn down. This is separate from Part A — Part A covers the loss of that undamaged portion's value; Part B covers the physical cost of demolishing it. Both are needed.
Part C — Increased Cost of Construction
Part C is often the most significant component in Florida. It covers the additional construction cost to rebuild to current code rather than original construction standards. This includes: hurricane straps and metal connectors now required but not present in older construction; enhanced roof deck attachment requirements; updated underlayment specifications; impact-resistant window and door requirements triggered by permit; and any other code-driven upgrade costs that the standard policy won't cover because they exceed restoring pre-loss condition.
Why Florida Properties Are Particularly Exposed
Florida properties face a larger ordinance or law exposure than most states for two reasons:
- Older building stock: Florida has significant housing stock built before the 2002 Florida Building Code — in some cases, before the 1994 post-Andrew revisions that first introduced modern wind resistance requirements. The code gap between 1980s construction and current standards is substantial.
- Strict hurricane codes: The Florida Building Code's wind resistance requirements are among the most demanding in the country. When a storm triggers a repair requiring permits — which in Florida includes most roof replacements — the entire roofing system must meet current code, including components that were not part of the original covered loss.
The practical consequence: a Florida property owner with a 1988-built home whose roof is 60% destroyed by a hurricane may find that their insurer's payment covers the 60% replacement cost at 1988 standards, while current building code requires a full roof system meeting 2026 standards. The gap — hurricane straps, enhanced decking attachment, required underlayment — is the property owner's problem without ordinance or law coverage.
Many Florida jurisdictions apply a "50% rule": if the cost to repair a damaged structure exceeds 50% of the structure's pre-damage value, the entire structure must be brought into compliance with current building code — not just the damaged portion. This can convert a partial storm loss into a full code-compliance rebuild project. Properties built before modern wind resistance codes face the largest exposure here. Ordinance or law coverage at adequate limits is essential for any building that could trigger this threshold after major hurricane damage.
What Happens Without It: A Real Scenario
A 1987-built rental property with $300,000 Coverage A and 10% ordinance or law coverage (the policy default) sustains significant hurricane roof damage. The adjuster values the covered loss at $45,000. However:
- The building permit triggers current code requirements for the entire roof system
- Current code requires hurricane straps throughout — the 1987 construction has none: $8,000
- Current code requires specific roof-to-wall connections: $4,500
- Enhanced decking attachment per current code: $3,200
- Current underlayment specification: $1,800
- Total code upgrade costs: $17,500
- Policy pays (10% of $300,000 Coverage A): $30,000 in ordinance or law coverage
- All code upgrade costs are covered at 10% limit — but only because the loss wasn't larger
Now run the same scenario with $150,000 in total code upgrade costs on a larger commercial building. At 10% ordinance or law ($30,000), the gap is $120,000 out of pocket. At 50% ($150,000), the exposure is covered.
How to Add It and How Much to Get
Ordinance or law coverage is typically available as an endorsement on standard Florida property policies. Some policies include it at a default limit (usually 10% of Coverage A); others require it to be explicitly added.
- For post-2002 construction: 10–25% of Coverage A is often adequate, as the construction gap between original code and current code is smaller
- For 1994–2002 construction: 25–50% of Coverage A is a reasonable starting point
- For pre-1994 construction: 50% or more of Coverage A may be warranted, particularly for buildings in high wind zones
- For commercial or multi-unit properties: consult a contractor and your agent to estimate actual code upgrade costs for your specific building type
Some policies offer ordinance or law coverage as a single combined limit, while others offer Parts A, B, and C separately with individual sublimits. Check your policy declarations page and endorsements to confirm which parts are included and at what limits. A policy that includes Part C (Increased Cost of Construction) but not Part A or Part B provides incomplete protection. Ask your agent to confirm explicitly that all three parts are covered.

Start Free — No Card Required →The Bottom Line
Ordinance or law coverage is not an optional add-on for Florida property owners — it is a necessary component of a complete property insurance program, particularly for buildings constructed before the 2002 Florida Building Code. The default 10% limit in most policies is insufficient for older construction where the gap between original and current code standards is substantial. Review your current ordinance or law limit, assess your building's construction year and type, and increase the limit if the default doesn't match your actual exposure. The premium increase is modest; the out-of-pocket exposure without adequate coverage is not. For a broader view of Florida insurance policy components, see the Florida insurance endorsements guide.
