🏠 US Homeowners Insurance Coverage Calculator & Replacement Cost Estimator (All 50 States)

Most HO-3 policies cover mold only when it results from a sudden, covered peril like a burst pipe — and typically cap payouts at $5,000–$10,000. Gradual mold from long-term leaks, humidity, or flooding is excluded. Florida, Texas, and Louisiana offer special mold endorsements ($50–$150/year) that raise the cap to $50K+.

Yes — under Coverage B (Other Structures), usually limited to 10% of your Coverage A. A $400,000 dwelling typically has $40,000 for garages, sheds, fences, and driveways. If you have a high-value workshop or detached ADU, you can raise this limit via endorsement.

Yes — Coverage C follows your belongings worldwide, including inside a vehicle. If your laptop is stolen from your parked car, your home policy pays (minus deductible). Your auto policy only covers the car itself, not personal items inside it.

Most HO-3 policies cover trees, shrubs, and landscaping at 5% of Coverage A, capped at $500 per tree. Coverage applies only for specific perils: fire, lightning, explosion, vandalism, theft, or falling aircraft — NOT wind or ice. If your neighbor’s tree falls on your house, your policy pays; if a healthy tree just falls in your yard with no damage, it’s usually not covered.

US homeowners premiums rose an average of 22% in 2025 due to four factors: (1) climate-driven catastrophe losses, (2) construction material inflation, (3) reinsurance cost increases, and (4) carriers exiting high-risk states. If your jump exceeded 25%, shop 3–5 competing quotes — carrier pricing varies by 30–50% for the same home.

Yes — in 47 US states, insurers legally use a credit-based insurance score (different from your FICO). Excellent credit can cut premiums 20–40%. California, Maryland, and Massachusetts restrict or ban this practice. Pay down credit utilization below 30% before your renewal date for the biggest impact.

Absolutely. Roofs 15+ years old often trigger premium surcharges or ACV-only coverage. Roofs over 20 years may be declined entirely. A new impact-resistant (Class 4) roof can cut your wind/hail premium by up to 35% — worth documenting with photos and receipts at your next renewal.

Multi-policy bundling typically saves 10–20%. State Farm, Allstate, USAA, Liberty Mutual, and Progressive all offer bundle discounts. Always compare the bundle total to two separate best-in-class quotes — sometimes unbundling beats bundling by $200–$400/year.

Most US insurers tolerate one claim every 3–5 years. Two claims within 3 years often triggers non-renewal at your next cycle. Water damage and liability claims raise the biggest red flags. If a claim is under $2,500, it’s usually better to pay out of pocket than risk your rating.

You have four escalation options: (1) request a written denial reason, (2) file a formal appeal with the insurer, (3) invoke your policy’s Appraisal Clause for disputed amounts, (4) file a complaint with your state Department of Insurance (free and effective). Hiring a licensed public adjuster (10% fee) can also recover 30–70% more on denied or underpaid claims.

Most policies require “prompt notice” — usually interpreted as 30–60 days for property damage and 1 year for liability. Check your dec page for the exact deadline. Filing later isn’t always denied, but insurers often reduce payouts citing difficulty in verifying damage.

Yes — you have the legal right to choose any licensed contractor. Insurers may “recommend” their preferred vendor network, but they cannot require you to use them. Get 2–3 independent estimates and submit them alongside the insurer’s estimate for any supplement negotiations.

Always choose RCV (Replacement Cost Value) if available. ACV (Actual Cash Value) subtracts depreciation — a 10-year-old roof pays only 50% of a new one’s cost. RCV costs 5–10% more in premium but can pay 2–4× more on a claim. Many insurers now default to ACV for roofs in hail-prone states; fight for RCV in writing.

HO-3 covers the dwelling on an open-peril basis and contents on a named-peril basis. HO-5 covers BOTH on open-peril with RCV by default — meaning the insurer must prove your loss is excluded rather than you proving it’s covered. HO-5 costs 15–30% more but is often worth it for homes over $500K or with valuable contents.

Yes — lenders require Coverage A equal to at least your mortgage balance. Many also require the loss payee clause (mortgagee clause) listing them by name. Some lenders force-place expensive coverage if yours lapses; set up auto-pay and escrow to prevent this.

Yes — you can cancel any time. Most insurers refund the unused premium on a pro-rata basis. A few use “short-rate” cancellation with a 10% penalty, so read your policy. Never cancel before the new policy is active — even a 1-day gap can be a mortgage violation and loses you continuous-coverage discounts.

Yes — 25% of all US flood claims come from low-risk zones. Standard HO-3 never covers flood. NFIP policies cost $400–$900/year in moderate zones and $1,500–$4,000/year in high-risk zones. Private flood insurance (Neptune, Flood Simple) is often 20–40% cheaper with higher coverage limits.

Limited. Standard policies cap business property at $2,500 in-home and $500 off-premises. If you’re a remote W-2 employee, that’s usually enough. Self-employed and client-facing businesses need either an endorsement ($50–$150/year) or a separate business owners policy (BOP). Liability for client injuries is NOT covered by Coverage E.

Your insurer pays the lesser of the replacement cost or actual rebuild cost. If your $400K Coverage A home is rebuilt as a $300K smaller home, you receive $300K — not the full $400K. Some policies include “cash-out” clauses letting you keep the difference; read carefully.

No. Standard HO-3 explicitly excludes commercial use. Airbnb’s Host Guarantee is NOT insurance. You need one of: (1) an STR endorsement on your HO-3 ($200–$500/year), (2) a standalone STR policy (Proper Insurance, Farmers HomeSuite — $1,500–$3,500/year), or (3) a commercial BOP if rentals are your primary business.
