Ordinance or Law coverage — why current code can add 10-25% to your rebuild
By Severance Calculator Editorial · Updated
The problem
A home built in 1985 was built to the 1985 building code. After a covered loss, the rebuild must comply with the 2024 International Building Code (or the state-amended version): updated electrical (AFCI/GFCI throughout, 200-amp service), updated plumbing (low-flow fixtures), energy code (R-49 attic insulation in most zones, low-E windows), accessibility where applicable, and — in hurricane and seismic zones — substantial structural upgrades (hurricane straps, sheathing nailing patterns, hold-downs). Standard HO-3 covers the cost to rebuild the house as it was; Ordinance or Law (Coverage E) covers the increment to bring it to code.
The data
Typical Coverage E defaults run 10% of Coverage A — $40,000 on a $400,000 policy. Actual code-upgrade cost on a 1980s-era home in a hurricane or seismic zone often runs 15-25% of rebuild cost. Florida post-Hurricane Andrew (1992 Florida Building Code), California post-Northridge (1997 UBC seismic), and Texas post-Hurricane Ike (2009 IRC wind provisions) all created step-changes in the code-vs-existing gap. United Policyholders and the Florida OIR have documented Ordinance or Law underinsurance as a top-3 systematic gap post-disaster.
What to do
Increase Ordinance or Law (Coverage E) to 25% of Coverage A — most carriers offer this as a low-cost endorsement ($30-$120/yr). If your home is older than the most recent major code adoption in your state (Florida 2001, California 2019, Texas 2015 IRC), 50% Coverage E may be defensible. Pair this with Extended Replacement Cost on Coverage A so the full envelope (rebuild + code upgrade) is funded. Read the policy form — some carriers split Coverage E into A/B/C (demolition, increased cost of construction, loss to undamaged portion) with separate sub-limits.
