Quick Answer: Why Ordinance or Law Coverage Matters
- Covers code‑mandated upgrades after a covered loss
- Applies to electrical, plumbing, roofing, energy code, egress
- Prevents surprise out‑of‑pocket for required compliance
- Older housing stock + evolving codes
- Storm‑driven rebuilds expose code gaps
- Upgrades can add 10–25%+ to rebuild costs
What Is Ordinance or Law Coverage?
Ordinance or Law coverage (often abbreviated O&L) pays for the extra costs to repair, rebuild, or demolish parts of your home as required by current building codes after a covered loss. Standard dwelling coverage pays to put damaged portions back the way they were; O&L helps bridge the gap to make them code‑compliant today.
Part A: Undamaged Portion
If code requires removal/rebuild of undamaged areas (e.g., full roof replacement), O&L can contribute.
Part B: Demolition
Costs to demolish undamaged parts mandated by code.
Part C: Increased Cost of Construction
Upgrades to current code: electrical panels, GFCIs/AFCIs, roof decking, egress, energy code, sprinklers where required.
What it doesn’t do
It does not pay to proactively upgrade an intact home; it applies after a covered loss triggers code enforcement.
When Does O&L Apply in Tennessee?
- Covered loss first: Fire, wind/hail, lightning, etc. must trigger the claim.
- Code enforcement: Building officials require upgrades/demolition to meet current code.
- Scope: Applies to undamaged parts when code mandates replacement; applies to upgrades on damaged parts to meet code.
- Older homes: The older the home, the larger the code gap—and the higher the potential O&L costs.
- 2022 energy code adoption increased insulation and HVAC efficiency standards.
- AFCI/GFCI electrical protections required across most circuits.
- Roofing standards updated for high‑wind resistance in Davidson County.
Covered vs. Not Covered (Code Upgrades)
| Typically Covered (with O&L) | Typically Not Covered | Notes for Nashville |
|---|---|---|
| Full roof replacement when code disallows partial tie‑ins | Voluntary upgrades before a loss | Common after wind/hail where decking/underlayment standards changed |
| Electrical panel upgrades to current code (AFCI/GFCI) | Pre‑existing violations not related to the loss | Expect inspection‑driven changes during rebuilds |
| Egress windows/doors and smoke/CO requirements | Undamaged outbuildings unless mandated | Older basements/bedrooms often need egress updates |
| Energy‑code upgrades (insulation, HVAC efficiency) | Lot‑line changes or zoning issues | Energy standards have tightened in recent cycles |
Typical Limits and Choosing 10–25%+
- Common limits: 10%, 15%, 25% of Coverage A; higher options may be available.
- Older homes, bigger gaps: Homes built before major code cycles (e.g., pre‑2000) often benefit from 20–25%+.
- Complexity factor: Historic details, masonry, and additions increase code‑driven costs.
- Roof and electrical: Two frequent cost drivers during code‑triggered rebuilds.

Choose a limit that aligns with your home’s age, complexity, and likely upgrade requirements.
| Home Age | Typical O&L Need | Common Upgrades | Recommended Limit |
|---|---|---|---|
| 0–10 yrs | Minimal | Roof decking only | 10% |
| 10–25 yrs | Moderate | Electrical + roof | 15% |
| 25+ yrs | High | Panel, egress, insulation | 25% |

| Scenario | Coverage A | O&L Limit | Code Costs | Insurer Pays (O&L) | You Pay |
|---|---|---|---|---|---|
| Fire with panel + egress upgrades | $400,000 | 10% ($40,000) | $38,000 | $38,000 | $0 |
| Wind roof + full code deck/vent | $500,000 | 10% ($50,000) | $62,000 | $50,000 | $12,000 |
| Major rebuild with energy/electrical | $650,000 | 25% ($162,500) | $150,000 | $150,000 | $0 |
What O&L Costs in Nashville (2025)
Pricing varies by carrier, home age/complexity, roof type, electrical/plumbing age, and claims history. As a rider or built‑in percentage, Ordinance or Law coverage in Nashville is generally a modest addition relative to potential code costs.
| O&L Limit | Illustrative Annual Cost Add‑On | Best For |
|---|---|---|
| 10% | $20–$60 | Newer homes; limited expected upgrades |
| 15% | $35–$95 | Mixed‑age neighborhoods; typical code gaps |
| 25% | $70–$180 | Older/historic homes; roof/electrical uncertainties |

Why Older Nashville Homes Need Ordinance or Law Coverage
Aging Electrical
Legacy panels, limited circuits, and absent AFCI/GFCI protections increase upgrade needs after a claim.
Roof Systems
Decking, ventilation, and underlayment standards have evolved—partial fixes may be disallowed.
Egress & Safety
Basement bedrooms and older layouts often need egress updates and additional smoke/CO devices.
Energy Requirements
Insulation and HVAC efficiency changes can add material labor and cost during rebuilds.
Pre‑Loss Steps to Control Code Costs
Pre‑Inspections
Electrical and roof assessments reveal likely upgrades; plan O&L limits accordingly.
Documentation
Keep records of prior permits and upgrades—helps adjusters align scope to code.
Scope Alignment
Ensure contractors quote code‑compliant assemblies to avoid late surprises.
Right‑Sizing Limits
Pair O&L with adequate dwelling limits and replacement cost on contents.
How O&L Interacts with Other Coverages
| Coverage | Role | Interaction with O&L | Notes |
|---|---|---|---|
| Dwelling (Coverage A) | Repairs damaged portions to pre‑loss condition | O&L adds code‑required costs above base repairs | Ensure replacement cost valuation is accurate |
| Extended/Guaranteed RC | Extra % beyond Coverage A for rebuild inflation | Complements O&L when costs spike post‑storm | Common in storm‑prone markets |
| Water Backup | Backups via drains/sumps | O&L may apply if code requires upgrades during repair | Separate endorsement with sub‑limits |
| Flood | Overland/rising water | NFIP policies have limited ICC (Increased Cost of Compliance) | Verify ICC details and eligibility |
Realistic Claim Scenarios: With vs Without O&L
Wind/Hail Roof Damage — With O&L
Code prohibits partial tie‑ins; entire slope replaced with updated decking/vent. O&L pays the incremental code costs.
Kitchen Fire — With O&L
Panel upgrade, AFCIs, added smoke/CO devices installed during rebuild. O&L covers the increase over standard repair costs.
Basement Bedroom — Without O&L
Repair covered, but new egress window and stair changes required by code fall to the homeowner without O&L limits.
Major Rebuild — With 25% O&L
Historic home requires extensive code upgrades. A 25% limit absorbs substantial increased construction costs.
