National cost-data averages published by Angi give a real, sourced starting point — even though your actual quote depends on the specifics of your project.
Structural engineering fees vary more than most other home-project costs, which makes them hard to estimate from a quick search. Rather than invent a number, here’s what Angi’s published home-services cost data — compiled from national pricing research — actually reports, along with the factors that explain the spread.
What the published data shows
According to Angi’s structural engineering cost guide, the average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500 depending on the scope of work.[1] Angi’s data further breaks down structural engineer fees by billing structure: per-project flat fees, a percentage of renovation cost (typically 1–5%), hourly rates (commonly $100–$250), and per-square-foot pricing.[1]
| Service Type | Typical Cost Range (Angi) |
|---|---|
| Structural inspection/calculations (flat rate) | $300 – $800[1] |
| Load-bearing wall assessment | $300 – $1,000[1] |
| Roof structural assessment | $150 – $600[1] |
| Chimney structural assessment | $200 – $500[1] |
Angi’s guide also notes that a structural engineer’s fee typically covers the engineer’s time, on-site consultation, evaluation of the property’s structural integrity, and the written findings report — but does not typically include trip charges, general contractor fees, permitting fees, or the actual cost of any recommended repair work.[1]
What drives the cost up or down
Scope of work
A narrow assessment — one wall, one crack pattern — sits at the lower end of the ranges above; a full structural evaluation of an addition or new build involves more calculation and lands higher.
Billing structure
Whether the engineer bills as a flat project fee, a percentage of renovation cost, hourly, or per square foot changes how the final number is calculated, even for similar-sized jobs.[1]
What’s included versus billed separately
Since trip charges, permitting fees, and repair costs typically sit outside the base engineering fee,[1] two quotes that look different on paper may reflect different assumptions about what’s bundled in.
Describe your project and we’ll give you an actual quote based on its scope — not a national average.
