Methodology & Local Data Sources

How we estimate fireplace installation costs in Ontario: Our local cost figure of $9,273 for Ontario, CA is calculated by adjusting the national mid-range baseline of $8,000 using two location-specific factors:

1. Labor adjustment, 55% of the project cost is treated as labor. That share is scaled by the ratio of the BLS OEWS May 2025 median hourly wage for Brickmasons & blockmasons in the Riverside-San Bernardino-Ontario, CA metro ($30.45/hr) to the U.S. median for the same occupation ($29.87/hr), a factor of 1.02. BLS publishes employee wages, not contractor billing rates, so only the ratio is used; the wage itself is not a quote.
2. Materials adjustment, 45% of cost is treated as materials, scaled by HammerIO's modeled material cost index for Ontario of 133 (national baseline = 100). The BLS Producer Price Index tracks national construction-material price trends; it does not publish a city-level index, so this regional factor is an estimate.
3. Permit fees are shown as a modeled allowance of $1,742 for Ontario. Actual permit costs follow the local fee schedule and vary by project scope, valuation, and inspection requirements set by the local building department.
4. Scope pricing for this project in Ontario: quotes should be compared by equipment, design, access, permit, and finish assumptions rather than a square-foot shortcut.
