California valuation note: this estimate covers the cost to reconstruct the dwelling and attached structures only. Per California valuation guidance it excludes land value, market/sale value, and personal belongings (Coverage C). It is an educational ballpark, not an appraisal, quote, or final insured value.

How It's Calculated

A component-based engine β€” the way a rebuild estimate is actually assembled

Rather than a single price-per-foot, the estimator layers the same cost components a professional replacement-cost valuation uses, consistent with industry methodology (IRMI / RSMeans-style regional indexing) and California valuation guidance.

1 Β· Regional cost basis

A California region (or ZIP) sets the base reconstruction cost per square foot, reflecting local labor and material indices. Los Angeles, the Bay Area, and rural Northern California differ substantially.

  • Region-indexed base $/sq ft
  • Contractor partner rates can override the basis
  • Production build connects live cost APIs

2 Β· Structure, materials & systems

Construction grade, stories, exterior, roof, foundation, interior finish, HVAC, and electrical/plumbing each adjust the effective rate, compounding into a realistic per-foot figure.

  • Construction grade: economy β†’ luxury
  • Material multipliers for roof & exterior
  • Systems and finish complexity
  • Age / code-complexity factor

3 Β· Features & attached structures

Distinctive cost drivers are added as discrete line items rather than buried in the rate, so the estimate reflects what actually has to be rebuilt.

  • Attached garage by size
  • Fireplaces (per unit)
  • Premium built-ins & millwork
  • Covered patio / deck area

4 Β· Rebuild conditions

Total-loss rebuilds cost more than new construction. The engine layers the real-world friction that drives that gap.

  • Site access & slope difficulty
  • Wildfire / WUI rebuild friction
  • Debris removal & demolition
  • Permits, plans & supervision (soft costs)

5 Β· Code & market conditions

Two factors that routinely cause underinsurance in California are made explicit and adjustable.

  • Ordinance-or-law code-upgrade allowance
  • Post-disaster contractor demand surge
  • Inflation-aware 2026 cost basis

6 Β· What it excludes

The calculation deliberately leaves out everything that is not part of rebuilding the structure itself.

  • Excludes land value
  • Excludes market / sale value
  • Excludes personal property (Coverage C)
  • Educational disclosure on every report

For Contractors

Built to plug in verified contractor rates

This estimator is designed to be licensed and co-branded. Partner general contractors supply their own per-square-foot reconstruction rates by construction grade and region; the engine uses those rates, and each report links back to the contractor's site and offerings.

GC
Sample Partner GC (example)Example contractor cost basis

Select "Sample Partner GC" in the estimator's Cost Basis to see how a contractor's verified rates replace the generic regional basis. Real partners provide their own numbers.

Economy / builder grade$235 / sq ft
Standard grade$280 / sq ft
Semi-custom grade$330 / sq ft
Custom / high-end$400 / sq ft
Luxury / bespoke$520 / sq ft

Good To Know

Why your replacement cost may differ from what you expect

Market value is not rebuild cost

Land, school district, and neighborhood demand push market value above or below reconstruction cost. Coverage A should track rebuild economics, not your purchase price or a Zillow estimate.

Older homes can cost more to rebuild

Period detail, plaster, custom windows, and code-driven upgrades can make an older home cost more to reconstruct than its square footage alone suggests.

Wildfire zones raise rebuild cost

Slope, access, labor demand, debris, and post-event conditions can sharply increase rebuild pricing in wildfire-exposed areas β€” even for a straightforward home.

Underinsurance is common

Code-upgrade costs and post-disaster demand surge are the two factors most often missing from a dwelling limit. This tool makes both explicit so you can see their impact.
