Common Homeowners Endorsements (Scheduled Property, Water Backup, Ordinance or Law)

Tailoring the Policy with Endorsements

The unendorsed homeowners form leaves predictable gaps: sublimits on valuables, no coverage for sewer/drain backup, and limited coverage for rebuilding to current code. Endorsements modify the base form to close those gaps. Each ISO endorsement carries a form number and edition (e.g., HO 04 90, HO 04 95, HO 04 77). Exam questions test which endorsement solves a stated problem and how its trigger differs from the base policy.

Scheduled Personal Property - HO 04 61 (Scheduled Personal Property Endorsement)

Coverage C contains special limits of liability (sublimits) on certain high-value categories. Without scheduling, an insured can be drastically underinsured on jewelry or other valuables.

The Scheduled Personal Property endorsement schedules each item by description and value, providing broader "all-risk" coverage, no deductible, and coverage for mysterious disappearance. It often requires an appraisal for high-value items and pays the lesser of the scheduled amount or the cost to repair/replace. Trap: scheduling raises the limit and broadens the perils - it is not merely a higher dollar amount.

Remember the sublimits operate two ways: most are theft-only caps (jewelry, furs, firearms, silverware), meaning a fire that destroys $10,000 of jewelry is paid in full under Coverage C, but a theft of the same jewelry is capped at $1,500 unless scheduled. Money and securities are limited for all perils. Scheduling removes both the peril limitation and the dollar cap, which is why it is the standard recommendation for engagement rings, fine art, and collectibles.

Water Back-Up and Sump Overflow - HO 04 95

The base homeowners form excludes water that backs up through sewers or drains or that overflows from a sump/sump pump. The Water Back-Up and Sump Discharge or Overflow endorsement buys this exposure back, typically with a separate aggregate limit selected by the insured (commonly $5,000, $10,000, or $25,000) and its own deductible.

Watch the distinction:

• Water back-up endorsement = water entering from sewers/drains/sump originating inside or below the system.
• Flood = surface water/rising water from outside; never covered by homeowners or this endorsement - it requires a separate NFIP flood policy.

Confusing back-up with flood is one of the most common P&C exam traps.

Ordinance or Law - HO 04 77

When a building is damaged, local building codes may require the undamaged portion to be brought up to current standards during reconstruction. The base form provides only limited (often 10%) ordinance-or-law coverage. The Ordinance or Law endorsement increases that protection, covering three cost categories:

1. Loss to the undamaged portion that must be demolished to comply with code.
2. Demolition cost of the undamaged portion.
3. Increased cost of construction to rebuild to current code.

Limits are commonly expressed as a percentage of Coverage A (e.g., increasing built-in 10% up to 25%, 50%, or 100%). Older homes in jurisdictions with updated codes need this most - without it, the insured pays code-upgrade costs out of pocket.

The coverage matters because building codes change over time: wiring, plumbing, insulation, hurricane strapping, and accessibility rules in force today may far exceed those in place when an older home was built. After a covered loss, the city can refuse a rebuild permit unless the entire structure meets current code. Ordinance or Law fills the gap between what it costs to replace what was there and what it costs to build a code-compliant structure - a gap the standard replacement-cost provision specifically excludes beyond the small built-in percentage.

Other Frequently Tested Endorsements

Worked example - Personal Property Replacement Cost: A 6-year-old sofa with a $1,500 replacement cost and 50% depreciation has an ACV of $750. Under the base policy, Coverage C pays $750. With HO 04 90 added, the policy pays the full $1,500 RCV (subject to deductible and limit).

On the exam, focus on the trigger and gap each endorsement addresses rather than memorizing every form number. Three patterns recur:

• Buy-back of an excluded peril - the base form excludes a peril entirely (earthquake, water back-up), and the endorsement restores it with its own limit and deductible.
• Scheduling a sublimited category - the base form caps a category (jewelry, firearms), and the endorsement schedules it for broader, higher coverage.
• Upgrading valuation - the base form settles at ACV or a small percentage (personal property, ordinance or law), and the endorsement upgrades to replacement cost or a higher percentage of Coverage A.

Matching a fact pattern to one of these three categories answers most endorsement questions correctly.
