Ordinance Upgrade Gap Calculator

When an older building is damaged, current code often requires upgrades (ADA, seismic, fire sprinkler, energy) plus demolition of undamaged portions. Standard property policies give small O&L limits. This calculator shows the gap between likely exposure and endorsement coverage.

How the math works

Ordinance and Law (O&L) coverage pays for: (1) demolition of undamaged portions required by code, (2) cost to meet current code when rebuilding. Many older buildings have major code gaps — 20-30% of replacement cost can be pure code upgrade.

Standard property policies give minimal O&L limits. Older buildings need higher O&L endorsement limits — typically 25-50% of replacement cost for code upgrade and separate demo coverage.

Frequently Asked Questions

Why is O&L needed?

Newer codes may require sprinklers, ADA compliance, seismic upgrades, etc. After damage, you can't rebuild to 1970s code — you must meet today's. O&L pays the difference.

How much coverage?

Older buildings (pre-1985): 25-50% of RC for code upgrade + 25% for demo. Newer buildings: 10-15% of RC. Always confirm local building code requirements — some cities mandate specific upgrades on any damage over 50% of value.

Three coverages?

A: damage to undamaged portions (forced demo). B: cost of demolition/debris removal. C: increased cost of construction. Most policies bundle them but sub-limits vary. Check each on your declarations page.
