How much dwelling coverage do I actually need?

Set your dwelling coverage at the cost to rebuild your home from the ground up, not at its sale price. For most Georgia homes, a starting estimate is square footage multiplied by a local per-square-foot construction cost, plus an allowance for upgrades. Then add endorsements that keep the number current as construction costs rise.

What is the difference between rebuild cost and market value?

Market value is what a buyer would pay for your home. It bundles in the land, the school district, and the mood of the housing market. Rebuild cost is the labor and materials needed to put the same house back on the same lot after a total loss. The land survives a fire, so you do not insure it.

Georgia’s Office of Commissioner of Insurance and Safety Fire tells homeowners that the amount of insurance you buy should be based on rebuilding costs, not the market value as determined by a real estate agent or by the local property tax appraiser. The two numbers often sit far apart. In an older intown neighborhood, the lot can be most of the price, so rebuild cost runs below market value. In a newer subdivision, rebuilding one home without a builder’s bulk pricing can cost more than it would sell for.

How do I estimate my rebuild cost?

Start with square footage times a local reconstruction cost, then adjust for what makes your home yours.

• Square footage. Use finished, heated space from your county property record or appraisal.
• Local cost per square foot. Reconstruction pricing varies by market and by year. Your agent’s replacement cost estimator carries current local figures.
• Features. Custom kitchens, hardwood floors, masonry exteriors, high ceilings, and finished basements all raise the rebuild number.

For illustration, a 2,400 square foot home in Athens at $165 per square foot pencils out to $396,000 in dwelling coverage before feature adjustments. Treat that as a planning figure, not a quote. We run a room-by-room replacement cost estimate with every homeowners insurance quote.

Why do dwelling limits fall behind?

Construction costs climb, and sometimes they jump. CoreLogic, now operating as Cotality, measured an average 16.6 percent spike in reconstruction costs nationally between the second quarter of 2020 and the second quarter of 2021. A dwelling limit set before a run-up like that can be short by tens of thousands of dollars.

Georgia’s insurance regulator also warns against settling for the common 80 percent threshold. Insuring for 80 percent of replacement cost, the standard coinsurance line in many policies, can leave you underinsured if you have a total loss. The regulator’s guidance is to carry coverage equal to the full cost of rebuilding, not a percentage of it.

Age cuts the other way too. The Insurance Information Institute notes that on older roofs, some policies pay actual cash value, which means depreciation comes out of the payout instead of the full replacement cost. If your roof is past fifteen years, ask how your policy treats it. Our explainer on actual cash value versus replacement cost walks through the math.

What add-ons close the gap?

An endorsement is an add-on that changes what your base policy pays. A few exist to keep your dwelling limit from drifting below real costs.

• Inflation guard nudges your dwelling limit upward at each renewal so it tracks construction costs instead of freezing in place.
• Extended replacement cost adds a cushion above your limit, commonly 25 to 50 percent, for years when rebuilding costs outrun estimates, such as when a major hailstorm spikes contractor demand across a region.
• Ordinance or law coverage pays the extra cost of rebuilding to today’s building codes, which a decades-old home would not meet.

These add-ons cost little relative to the gap they close, yet many homeowners go without them. In 2022, the Insurance Information Institute, citing research from the American Property Casualty Insurance Association, reported that approximately two-thirds of insured U.S. homeowners could be without key additional coverages, including automatic inflation guard, extended replacement cost, and building code coverage.

What does this look like for a north Atlanta home?

U.S. Census Bureau figures put the median owner-occupied home value at $629,400 in Johns Creek and $649,000 in Alpharetta for 2020 through 2024. Those are market values, and they include the land, so they are not the number to insure. They do show the scale at stake in these neighborhoods.

For illustration only, a 3,200 square foot Johns Creek home at $175 per square foot of reconstruction cost needs about $560,000 in dwelling coverage before features. Add a brick exterior, a finished basement, and upgraded kitchens, and the rebuild estimate can climb past $600,000. A homeowner still carrying the limit set at purchase eight years ago could be $100,000 or more short. We cover that pattern in our piece on underinsured north Atlanta homeowners.

Your deductible is a lever here too. Raising it lowers your premium and frees up budget for a stronger dwelling limit.
