Making sure you have enough coverage

From Home Insurance in Colorado: What It Costs and What Actually Covers You

The most consequential number on your policy is the Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.

Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices, with today's labor. That is a construction number, not a real estate number. Market value includes your land, which does not burn down and does not get hailed on. Your mortgage balance is a financing number with no relationship to construction cost — someone who has paid a loan down to $120,000 still needs a full rebuild if the house is destroyed.

Working a real Colorado example

Rebuilding in Colorado runs roughly $220 per square foot — the midpoint of a published $160 to $280 band covering materials, labor, and general contractor overhead and profit, excluding land.

On a 2,200 square foot home:

  • 2,200 x $220 = $484,000 to rebuild

Now put that next to Colorado's median home price of about $563,000. The rebuild cost is roughly $79,000 below the median sale price — and that gap is essentially the land. This is the clearest illustration available of why market value is the wrong input: in Colorado, insuring to your purchase price generally means overpaying for coverage you cannot use, because you will never need to rebuild the lot.

Take the band seriously in both directions. At $160/sq ft, a 2,200 square foot home is $352,000. At $280/sq ft it is $616,000. That $264,000 spread is the honest width of a statewide construction figure. Colorado shares its exact cost band with eight other Mountain and Plains states, which makes it a regional construction-cost band applied to Colorado rather than a Colorado-specific survey — and Colorado's own cross-check figures run above most of the states sharing that band. Treat $220 as a starting point for a conversation with your agent, and get an actual replacement-cost estimate for your specific home. Mountain properties with difficult access, custom finishes, or non-standard construction can sit well above the top of the band.

The 80% coinsurance rule, and what a shortfall does to a partial claim

Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not simply cap your total payout at your limit — it reduces every partial claim proportionally.

Work it on the example. Full replacement cost $484,000, so the 80% threshold is $387,200. Suppose you carry the $300,000 reference limit and hail does $100,000 of damage. Your limit is three times the loss, so it feels safe. It is not:

  • $300,000 carried / $387,200 required = 0.775
  • 0.775 x $100,000 = $77,479
  • Then subtract your wind-hail deductible — 2% of $300,000 = $6,000
  • Net payment: about $71,479 on a $100,000 loss

You are roughly $28,500 short on a claim well inside your policy limit, purely because Coverage A was set too low. And if your roof also settles on an actual cash value basis — see the next section — the real number is worse than that.

Two endorsements worth asking about by name

  • Extended replacement cost — pays a stated percentage above your Coverage A limit (commonly 25% to 50%) if rebuilding costs more than expected. Valuable in a state where a single storm or fire can consume regional contractor capacity and push costs up at exactly the wrong moment.
  • Ordinance or law coverage — as above, covers the extra cost of building to current code.

Review your limit annually. Construction costs have moved sharply and a limit set five years ago is very likely too low.
