Home Insurance Preparation

Per IRC R312.1, guards are required on open sides of walking surfaces (including porches, balconies, and raised floor surfaces) located more than 30 inches above the floor or grade below. Guard height must be at least 36 inches for residential (42 inches for commercial per IBC 1015.3). Balusters must not allow passage of a 4-inch sphere (IRC R312.1.3). Insurance underwriters flag missing or non-compliant guards as a major liability risk.

1. Measure guard/railing height — must be at least 36" from the deck surface for residential

2. Test baluster spacing with a 4-inch sphere — it must not pass through at any point

3. Check structural integrity — push firmly against the railing; it must resist a 200 lb concentrated load per IRC R301.5

4. Verify that all posts are securely fastened to the deck framing (not just to decking boards)

5. Inspect for rot, corrosion, loose fasteners, or cracked welds on metal railings

6. Confirm guards are present on all open sides where drop exceeds 30 inches

7. Check stairway handrails — must be 34"–38" high and graspable (1.25"–2" diameter per IRC R311.7.8)

- Railing height below 36 inches (older homes built to previous codes)

- Baluster spacing exceeding 4 inches, especially on older wooden decks

- Rotted or corroded post bases from water pooling

- Deck ledger board improperly attached to house (no flashing, lag bolts missing)

- Missing guards on raised patios or porches homeowners don't consider "elevated"

Per NFPA 72 and IRC R314/R315, smoke alarms are required in each sleeping room, outside each sleeping area, and on every level of the home including basements. CO alarms are required outside sleeping areas on every level with fuel-burning appliances or attached garages. Alarms must be interconnected in new construction (IRC R314.3). Most insurers require functional detectors as a condition of coverage.

1. Verify smoke detectors are installed in every bedroom, hallway outside bedrooms, and on every floor

2. Verify CO detectors are present outside sleeping areas and near fuel-burning appliances (furnace, water heater, fireplace)

3. Test each detector using the test button — ensure audible alarm sounds

4. Check manufacture date on each unit — replace smoke detectors older than 10 years, CO detectors older than 5–7 years

5. Confirm detectors are mounted on the ceiling or high on the wall (within 12 inches of ceiling per NFPA 72)

6. Verify interconnection — when one alarm sounds, all should activate (required in homes built after 1993)

7. Document detector locations and test dates for the insurance file

- Missing detectors in finished basements or attic bedrooms

- Expired units still installed (no manufacture date check)

- Detectors painted over during renovations (sensors blocked)

- Battery-only units where hardwired interconnected units are required

- Detectors installed near kitchens or bathrooms causing nuisance trips (removed by homeowners)

Insurance underwriters evaluate roof condition as a primary factor in coverage eligibility and premium calculation. Most insurers require roofs to have a remaining useful life of at least 5 years. Per IRC R905, roofing materials must comply with wind resistance ratings (ASTM D3161 or D7158) and fire classification (Class A, B, or C per ASTM E108). In hurricane-prone regions, FBC (Florida Building Code) and IRC R903.5 require additional wind uplift resistance.

1. Determine roof age from building records, permit history, or prior inspection reports

2. Inspect shingles for curling, cracking, granule loss, or missing sections from ground level with binoculars

3. Check for sagging ridgelines or visible structural deformation

4. Inspect flashings around chimneys, vents, skylights, and wall intersections for deterioration

5. Examine gutters for excessive granule accumulation (indicates shingle wear)

6. Check attic for daylight penetration, water stains, or mold on sheathing

7. Verify impact-resistant shingles (Class 4 per UL 2218) in hail-prone areas — may qualify for premium discounts

8. Document roof material, age, and condition with photographs

- Roof over 20 years old with asphalt shingles (typical lifespan 20–30 years)

- Multiple layers of shingles (max 2 layers per IRC R907.3; insurers prefer single layer)

- Missing or damaged hip/ridge caps

- Improper flashing installation leading to chronic leaks

- No hurricane straps/clips in wind-prone regions (required by IRC R802.11.1)

Per NEC (NFPA 70) and IRC E3601–E3609, the electrical system must be properly grounded, circuits must be protected by appropriately sized breakers, and GFCI/AFCI protection must be installed where required. Many insurers will not cover homes with Federal Pacific, Zinsco, or certain Pushmatic panels due to known defect rates. Aluminum branch wiring (1965–1973 era) is also flagged as high-risk.

1. Identify the electrical panel brand — Federal Pacific (Stab-Lok), Zinsco, and certain Pushmatic panels are insurance red flags

2. Check panel amperage — 100A minimum for most insurers; 200A preferred for modern homes

3. Test all GFCI outlets in bathrooms, kitchen, garage, exterior, and basement (press test/reset buttons)

4. Verify AFCI breakers are present for bedroom circuits (required since NEC 2002)

5. Look for double-tapped breakers (two wires on one breaker), which is a code violation

6. Check for exposed or damaged wiring in accessible areas (attic, basement, garage)

7. Verify proper grounding — look for ground rod or Ufer ground connection at panel

8. Check for aluminum branch wiring (silver-colored at outlets) — requires COPALUM or AlumiConn connectors

- Federal Pacific or Zinsco panels (known breaker failure rates; many insurers require replacement)

- Aluminum branch circuit wiring without proper termination remediation

- Ungrounded outlets in older homes (2-prong) without GFCI upgrade

- Overloaded circuits or improper breaker sizing

- DIY wiring without permits (knob-and-tube remnants, exposed junction boxes)

Per IRC P2601–P2903 and Uniform Plumbing Code (UPC), supply and drain piping must be in serviceable condition with no active leaks. Polybutylene piping (1978–1995) is flagged by most insurers due to high failure rates. Water heaters must have temperature-pressure relief (TPR) valves with discharge piping per IRC P2803.6.1. Insurers increasingly offer discounts for whole-house water shutoff systems.

1. Identify supply pipe material — polybutylene (gray flexible pipe) is an insurance disqualifier for many carriers

2. Check for visible leaks under all sinks, around toilets, and at water heater connections

3. Inspect water heater age (typically 8–12 year lifespan) and verify TPR valve has proper discharge pipe

4. Look for water stains on ceilings and walls that indicate past or current leaks

5. Check washing machine hoses — replace rubber hoses with braided stainless steel

6. Verify main water shutoff valve is accessible and functional

7. Inspect sump pump operation if present (pour water to test activation)

8. Check for proper drainage slope away from foundation (6 inches drop in first 10 feet per IRC R401.3)

- Polybutylene supply piping (high failure rate; some insurers refuse coverage)

- Galvanized steel drain pipes corroded internally (pre-1970s homes)

- Water heater over 12 years old without recent service

- Missing or improperly routed TPR valve discharge

- No backflow prevention on sewer line in flood-prone areas

Per IRC Appendix G (Swimming Pools) and CPSC Guidelines, residential pools must have a barrier (fence) at least 48 inches high with self-closing, self-latching gates. The "attractive nuisance" doctrine holds homeowners liable for injuries to trespassing children from hazards like pools, trampolines, and play structures. Most insurers require pool fencing and may exclude or surcharge for trampolines.

1. Verify pool fence is at least 48 inches high on all sides (per IRC AG105.2)

2. Check that fence gate is self-closing and self-latching, with latch on pool side at least 54 inches high

3. Ensure no climbable objects (chairs, planters) are near the pool fence

4. Verify pool drain covers comply with Virginia Graeme Baker Act (anti-entrapment)

5. Check that a pool alarm or safety cover is installed (required in some states)

6. If trampoline is present, verify safety netting enclosure and check insurer's policy — some exclude trampoline injuries

7. Inspect playground equipment for structural integrity and fall zone surfacing (6 feet clearance per CPSC)

8. Document all safety measures with photographs for the insurance file

- Pool fence below 48 inches or with gaps allowing child access

- Non-self-latching gates or latches accessible to small children

- Trampoline without enclosure netting (insurance liability exclusion)

- Above-ground pool ladder left in place providing unsupervised access

- Tree houses or play structures without proper safety zones

Per NFPA 1 Fire Code and IRC R302, homes must maintain fire-rated separation between garage and living space (1/2" drywall minimum, 5/8" Type X on garage ceiling below living space per IRC R302.6). Fire extinguishers are recommended in kitchen, garage, and workshop areas (NFPA 10). In wildfire-prone areas (WUI zones), defensible space and fire-resistant materials are required and heavily weighted by insurers.

1. Verify fire-rated garage-to-house separation — minimum 1/2" drywall on garage walls, 5/8" Type X on ceiling if living space above

2. Check that the garage-to-house door is solid wood or 20-minute fire-rated and self-closing

3. Inspect fireplace and chimney — verify damper operation, check for creosote buildup, confirm spark arrestor on chimney top

4. Ensure at least one fire extinguisher (2A:10BC minimum) is accessible in kitchen area, plus one in garage

5. Check that dryer vent is rigid metal (not plastic/foil flex) and free of lint buildup

6. In WUI zones: verify defensible space (30 feet minimum clearance from structures per NFPA 1144), fire-resistant roofing and siding

7. Verify no combustible storage within 3 feet of water heater or furnace

8. Check that address numbers are clearly visible from the street for emergency response

- Missing or incomplete garage fire separation (exposed framing)

- Dryer vent clogged with lint or using combustible flexible duct

- No fire extinguishers in home (not code-required but insurance benefit)

- Vegetation or combustible materials against exterior walls in fire-prone areas

- Fireplace without spark arrestor or with deteriorated chimney liner

While not code-mandated, home security systems can qualify for insurance discounts of 5–20%. Per premises liability law, homeowners must maintain safe conditions for visitors. ADA-adjacent considerations (clear walkways, adequate lighting) reduce slip-and-fall liability. Deadbolt locks meeting ANSI/BHMA A156.5 Grade 1 or 2 are recommended by insurers.

1. Verify deadbolt locks on all exterior doors — minimum 1-inch throw bolt

2. Check that exterior lighting illuminates all entry points, walkways, and stairs

3. Inspect walkways and driveways for trip hazards (raised concrete sections, cracked pavement, uneven steps)

4. Verify handrails on all exterior stairs with 4 or more risers (per IRC R311.7.8)

5. Check window locks on all ground-floor and accessible windows

6. If a security/alarm system is installed, verify it is monitored and document for insurer discount

7. Inspect fencing for property boundary — ensure no gaps that could allow uncontrolled access by children or animals

8. Check for dog breed restrictions — some insurers exclude certain breeds; document all pets

- Uneven walkways or heaved concrete creating trip hazards

- Missing exterior handrails on porch or entry steps

- Inadequate exterior lighting at side or rear entries

- Broken or missing window locks on accessible windows

- Unfenced yard with known aggressive dog breed (insurance exclusion risk)

Per IRC R401–R404 and IBC Chapter 18, foundations must be structurally sound without evidence of significant settlement, movement, or water intrusion. Cracks wider than 1/4 inch or horizontal/stair-step cracks may indicate structural failure. Insurers may deny coverage or require engineering evaluation for homes with visible foundation distress. In seismic zones, cripple wall bracing and foundation bolting per IRC R403.1.6 are required.

1. Walk the exterior perimeter and inspect foundation walls for cracks — note width, direction, and pattern

2. Check for horizontal or stair-step cracks in block/brick foundations (indicates lateral pressure failure)

3. Look for water stain lines on foundation walls (indicates chronic water intrusion)

4. Verify crawl space or basement is dry with no standing water or active moisture

5. Check that the ground slopes away from the foundation on all sides (6" in 10' per IRC R401.3)

6. Inspect for visible settling — doors that don't close, cracks above window/door frames

7. In seismic zones: verify foundation bolting and cripple wall bracing if applicable

8. Document any foundation concerns with measurements and photographs

- Vertical settlement cracks wider than 1/4 inch

- Horizontal cracks from hydrostatic pressure in basement walls

- Missing or inadequate foundation drainage (no French drain or sump)

- Unbolted foundation in seismic zones (pre-1950s homes)

- Expansive soil damage causing cyclical movement

Per IRC M1401–M1411 and NFPA 54 (National Fuel Gas Code), heating and cooling systems must be properly installed, vented, and maintained. Gas appliances require proper combustion air supply and venting per IRC G2407 and G2427. Insurers consider HVAC age in underwriting — systems over 20 years old may trigger surcharges. Well-maintained systems with annual service records can support premium reductions.

1. Record age and condition of furnace/boiler (typical life 15–25 years) and AC unit (12–20 years)

2. Verify gas appliance venting — check for proper draft at draft hood, no visible corrosion or disconnected flue pipes

3. Ensure furnace filter has been changed recently (dirty filters increase fire risk and reduce efficiency)

4. Test thermostat operation — system should cycle on and off properly

5. Check for proper combustion air supply to mechanical room (per IRC G2407)

6. Inspect condensate drain line on AC for clogs (can cause water damage)

7. Verify that all gas connections use approved flexible connectors (not older brass or uncoated copper)

8. Document service history and any recent maintenance for insurance records

- HVAC system exceeding expected service life with no maintenance records

- Cracked heat exchanger in gas furnace (carbon monoxide risk)

- Disconnected or corroded vent piping on water heater or furnace

- Missing combustion air supply in enclosed mechanical rooms

- Outdated refrigerant (R-22) requiring expensive service or replacement

Per ANSI A300 Tree Care Standards and ISA (International Society of Arboriculture) best practices, trees with dead branches, disease, or structural defects that overhang structures or property lines represent a liability. Insurers may require removal of hazardous trees as a condition of coverage. Retaining walls over 4 feet require engineering per IRC R404.4. Proper grading and drainage protect against foundation and water damage claims.

1. Inspect all trees within falling distance of the house for dead limbs, trunk cavities, or visible disease

2. Check for branches overhanging the roof — trim back to at least 10 feet from the structure

3. Verify retaining walls are structurally sound with no bulging, leaning, or cracking

4. Ensure drainage directs water away from the foundation and neighboring properties

5. Check for dead or dying trees that could fall on power lines, fences, or neighbor's property

6. Inspect outdoor storage sheds and detached structures for structural soundness

7. Verify firewood and combustible materials are stored at least 30 feet from structures (in wildfire areas)

8. Check for standing water or poor drainage that could indicate future flooding claims

- Large dead trees or limbs overhanging the house (windstorm damage risk)

- Root damage to foundation or sewer lines from trees planted too close to house

- Leaning retaining walls without drainage relief (hydrostatic failure)

- Shed or outbuilding in poor condition (collapse risk, liability)

- Improper grading directing water toward the foundation

Insurance underwriters assess risk based on verifiable home condition. Maintaining organized documentation of home improvements, safety upgrades, and maintenance history supports better coverage terms. CLUE (Comprehensive Loss Underwriting Exchange) reports track prior claims and affect premiums. Various safety and resilience upgrades qualify for premium discounts depending on the carrier and state.

1. Obtain a CLUE report to review claim history (free annually from LexisNexis)

2. Gather documentation for all major upgrades: roof replacement, electrical panel upgrade, plumbing re-pipe

3. Collect permits and inspection records for any renovations or additions

4. Document home security system monitoring contract (5–20% discount potential)

5. Verify and document impact-resistant roofing or windows if installed (wind/hail discount)

6. Confirm smoke/CO detector interconnection and fire extinguisher placement (fire protection discount)

7. Document water leak detection or automatic shutoff system if installed (water damage discount)

8. Photograph the overall condition of the home exterior, roof, electrical panel, and major systems

9. Compile list of recent maintenance (HVAC service, chimney cleaning, tree trimming) with receipts

- No documentation of prior improvements (insurer defaults to original condition)

- Unknown prior claims on CLUE report affecting premiums

- Missing permits for additions or renovations (creates coverage gaps)

- Failing to claim available discounts for existing safety features

- Outdated home inventory for personal property coverage
