5.3 Common Homeowners Endorsements (scheduled property, water backup, ordinance or law)

Key Takeaways

  • Scheduled Personal Property (the floater, HO 04 61) insures listed valuables on an open-peril, agreed/stated-value basis, defeats the Coverage C special limits, and usually carries no deductible.
  • Water Backup and Sump Discharge or Overflow (HO 04 95) covers sewer/drain backup and sump-pump failure that the base policy excludes, typically with a $5,000-$25,000 sublimit.
  • Ordinance or Law (HO 04 77) pays the extra cost to repair or rebuild to current building codes, commonly providing 10%-50% of Coverage A.
  • Personal Property Replacement Cost (HO 04 90) upgrades Coverage C from ACV to replacement cost; Inflation Guard raises Coverage A automatically to track rebuilding costs.
  • An Earthquake endorsement uses a percentage deductible (commonly 10%-25% of Coverage A), not a flat dollar deductible.

Endorsements (also called riders or floaters) amend the base homeowners form to add coverage, raise a sublimit, or buy back an exclusion. The exam does not ask you to memorize every form, but it does expect you to match the problem to the endorsement that fixes it. Below are the high-frequency endorsements, each tied to the precise gap in the unendorsed ISO HO 00 03 policy.

Scheduled Personal Property (HO 04 61)

The base policy caps certain valuables with Coverage C special limits - for example, commonly $1,500 on jewelry/watches/furs for theft and $2,500 on business property on premises. A diamond ring worth $12,000 stolen from an unendorsed policy recovers only the $1,500 theft sublimit.

The Scheduled Personal Property endorsement (the 'floater') lists each item with an appraised value and insures it on:

  • an open-peril (all-risk) basis - broader than the base named perils;
  • an agreed/stated-value basis - no depreciation, no coinsurance argument;
  • usually no deductible.
Item typeBase Coverage C special limit (theft)With the floater
Jewelry, watches, furs~$1,500Full scheduled value
Silverware~$2,500Full scheduled value
Firearms~$2,500Full scheduled value

Trap: scheduling defeats the special limit only for the listed items. Unscheduled jewelry still falls under the $1,500 cap.

Water Backup and Sump Discharge or Overflow (HO 04 95)

The base homeowners policy excludes water that backs up through sewers or drains and water that overflows from a failed sump pump. (It is distinct from flood, which is excluded everywhere and requires a National Flood Insurance Program (NFIP) or private flood policy.)

The Water Backup endorsement buys back the sewer/drain/sump exposure, typically with a $5,000 to $25,000 sublimit and its own deductible.

Worked example: a finished basement floods when the municipal sewer backs up, causing $14,000 in damage. The insured carries a $10,000 water-backup sublimit with a $500 deductible. Recovery = $10,000 - $500 = $9,500; the insured absorbs the remaining $4,000 above the sublimit. Without the endorsement, the entire $14,000 is denied.

Ordinance or Law (HO 04 77)

When an older home is damaged, current building codes may force a more expensive rebuild than the original construction - new wiring, fire sprinklers, or full demolition of an undamaged portion. The base policy excludes this added cost. Ordinance or Law pays the extra expense to bring the structure up to code, commonly offered as 10%, 25%, or up to 50% of Coverage A.

Worked example: a fire damages 60% of a 1965 home. The straight repair would cost $180,000, but the code now requires updated electrical and a sprinkler system, adding $45,000. The base policy pays the $180,000 repair; the $45,000 code upgrade is paid only if Ordinance or Law is attached (here it is well within a 25% x Coverage A allowance on a $400,000 dwelling = $100,000 of available code coverage).

Other high-frequency endorsements

Endorsement (ISO form)The gap it fixesHow it works
Personal Property Replacement Cost (HO 04 90)Coverage C defaults to ACVPays replacement cost on contents - no depreciation
Inflation GuardCoverage A erodes against rising rebuild costsAutomatically increases Coverage A by a set percent over the term
Earthquake (HO 04 54)Earthquake is excludedAdds quake coverage with a percentage deductible, commonly 10%-25% of Coverage A, not a flat dollar amount
Identity Fraud ExpenseNo coverage for ID-theft recovery costsPays expenses to restore identity, often a $15,000-$25,000 limit
Home Business / Permitted Incidental OccupanciesBusiness pursuits excludedAdds limited liability/property coverage for a small in-home business
Scheduled Personal Property (HO 04 61)Coverage C special limitsOpen-peril, agreed-value coverage on listed items

Trap: the earthquake percentage deductible is a favorite distractor. A 15% deductible on $400,000 of Coverage A is $60,000 the insured pays before the policy responds - far larger than a typical flat deductible.

Matching Endorsements to Coverage Gaps

Each common endorsement fills a specific hole in the unendorsed HO form:

Gap in Base PolicyEndorsementEffect
Special limits cap valuablesScheduled Personal Property (HO 04 61)Open-peril, agreed value, no deductible on listed items
Sewer/drain backup excludedWater Backup & Sump Overflow (HO 04 95)Adds a sublimit, often $5,000-$25,000
Code-upgrade costs excludedOrdinance or Law (HO 04 77)Pays extra cost to rebuild to current code
Contents pay ACVPersonal Property RC (HO 04 90)Upgrades Coverage C to replacement cost
Inflation erodes Coverage AInflation GuardRaises Coverage A automatically
Earthquake excludedEarthquake endorsementAdds quake; uses a percentage deductible

The earthquake endorsement's percentage deductible (commonly 10%-25% of Coverage A) is a frequent exam point because it is far larger than the flat dollar deductible on the base policy.

Scheduling Valuables and Choosing Deductibles

The Scheduled Personal Property floater (HO 04 61) is the single most important endorsement for clients with valuables, and the exam tests three of its features together: it covers listed items on an open-peril basis, settles on an agreed or stated value supported by appraisal, and typically applies no deductible, while defeating the small Coverage C special limits (such as the $1,500 jewelry-theft cap). Mysterious disappearance of a scheduled ring is therefore covered, whereas it would not be under the base Coverage C named perils.

Deductible structure differs sharply by endorsement. The base policy uses a flat dollar deductible, but the earthquake endorsement uses a large percentage deductible (commonly 10%-25% of Coverage A), and many coastal homeowners carry a separate windstorm/hurricane percentage deductible. Recognizing that catastrophe endorsements switch to percentage deductibles measured on the dwelling limit, not the loss, is a frequent test point that mirrors the percentage-deductible math covered in the property-concepts chapter.
