The short answer
A structural engineer costs $100 to $500 an hour, and a foundation inspection $300 to $1,000 — $600 on average (This Old House, October 2026, drawing on Angi and Fixr data). An engineer writing for homeowners puts the usual residential rate at $100 to $250 an hour, a single-issue structural inspection at $300 to $700, beam calculations, a wall removal or a foundation assessment at $300 to $2,500 flat, and a foundation repair plan at $800 to $2,500 (HBG Civil, read November 2026).
Firms bill by grade. A Central California civil engineering firm's proposed 2026 schedule for the City of Kerman sets $250 an hour for its principal engineer, $150 to $225 for its civil engineers and $95 to $110 for CAD drafters, each rate built as the employee's pay times a 2.67 multiplier for benefits, overhead and a 10% fee (Yamabe & Horn, January 2026). A consulting firm's 2026 schedule for the City of Lebanon, Oregon, runs from $135 to $320 an hour across its nine engineer-scientist-specialist classes and $125 to $195 for CAD staff.
On bigger builds the fee is a share of the work: 5% to 15% of construction value (HBG Civil), with Monograph's guidelines putting MEP engineering at 5% to 15% and civil and infrastructure work on a sliding scale from about 6.8% on a $1–2 million project to 5.4% above $20 million (October 2026). The median civil engineer earns $48.48 an hour as an employee (O*NET, 2025 wages).

RATES · NOVEMBER 2026
Structural engineer cost and engineering rates (2026)
Two kinds of figures. What homeowners pay: This Old House's foundation inspection and hourly ranges (October 2026, drawing on Angi, Fixr and its own data) and a civil engineer's own flat-fee, hourly and percentage figures for residential work (HBG Civil, read November 2026). What firms bill: Yamabe & Horn's proposed 2026 schedule for the City of Kerman, California (January 1 to June 30, 2026, with a proposed 3% rise each fiscal year after) and a consulting firm's 2026 Schedule of Charges for the City of Lebanon, Oregon (January 1 to December 31, 2026). The two schedules are what two firms bill or propose to bill two cities — not a regional or national survey.

ADD-ONS AND ADJUSTMENTS
What changes the fee: who does the work, and the extras
Junior staff bill less than the engineer who stamps the work; soil testing and a stamped permit package are their own lines on a residential job.
| What | Typical US price · source |
|---|---|
| Who does the work: junior staff under a licensed engineer's supervision | $75–$120 an hour against the $100–$250 residential rate, with the stamping engineer's review billed separately · HBG Civil figures |
| Soil testing with an inspection | +$150–$400 · HBG Civil |
| Stamped, permit-ready package (when billed separately) | +$100–$500 · HBG Civil |

THE PRICING FORMULA
How to set your engineering fees
Six steps from an engineer's pay to the number on your proposal.
Build the rate from the pay
Yamabe & Horn's proposed Kerman schedule shows one firm's arithmetic: the employee's hourly pay × (1 + 142.70% for fringe benefits and overhead) × (1 + a 10% fee) — a 2.67 multiplier, so a principal paid $94.00 an hour bills $250.95, rounded to $250 (January 2026). That multiplier is one firm's benefits and overhead — work out your own before you use any multiplier.
Set a ladder by grade
One firm's proposed 2026 ladder runs $95 for a CAD drafter, $105 for an assistant engineer, $150–$225 for civil engineers and $250 for the principal (Yamabe & Horn, for Kerman, California); another firm's runs $135 to $320 across nine engineer-scientist-specialist classes, with CAD staff at $125–$195 (for Lebanon, Oregon).
Flat-fee the defined residential jobs
A single-issue inspection $300–$700, beam calculations, a wall removal or a foundation assessment $300–$2,500, a foundation repair plan $800–$2,500 (HBG Civil). A foundation inspection averages $600 across This Old House's $300–$1,000 range (October 2026). Say what the fee includes — the site visit, the report, the stamp — because an underpriced calculation can end in a rejected permit and a second engineer paid $500–$1,500 to redo it (HBG Civil).
Bill the open-ended work by the hour
$100–$250 an hour is the usual residential range, $300 or more for a senior principal on a complex case, and $75–$120 for junior staff under a PE's supervision, with the stamping engineer's review billed on top (HBG Civil). Hourly is the primary pricing model at 67% of architecture and engineering firms (Monograph, October 2026).
Use a percentage on the big builds
5%–15% of construction value, rare below a $50,000 budget and standard on commercial-adjacent residential work above $250,000 (HBG Civil). Monograph's guidelines: MEP engineering 5%–15% by facility complexity; civil and infrastructure about 6.8% on a $1–2 million project, 5.9% on $5–10 million and 5.4% above $20 million (October 2026).
List the extras and the yearly rise
Soil testing $150–$400 on top of an inspection and a stamped, permit-ready package $100–$500 where it's billed separately (HBG Civil). Put any escalator in writing: Yamabe & Horn's proposed Kerman schedule builds in 3% each fiscal year, and the Lebanon schedule bills outside costs at cost plus 10% and vehicles at the federal mileage rate.
Three jobs, priced
Say a homeowner wants a load-bearing wall out between the kitchen and the living room. HBG Civil's flat-fee band for beam calculations, a wall removal or a foundation assessment is $300–$2,500, and it tells of a wall job quoted at $650 that, with the site visit, a footing depth check and a revised beam, should have been billed at $1,400–$1,800; soil testing adds $150–$400 if the job needs it, and a stamped, permit-ready package $100–$500 where it's billed separately. Billed by the hour instead, 8 hours at $100–$250 is $800–$2,000.
A $300,000 addition, priced as a share: 5%–15% is $15,000–$45,000, and HBG Civil's own example at 8% is $24,000 — $28,800 if change orders take the build to $360,000, which is why the fee basis belongs in the proposal.
For your own ladder: a staff engineer you pay $45 an hour bills about $120 at the 2.67 multiplier in Yamabe & Horn's proposed Kerman schedule ($45 × 2.67 = $120.15) — one firm's benefits and overhead, so swap in your own. The median civil engineer earns $48.48 an hour (O*NET, 2025 wages). The rates are the publishers'; the job, the $45 wage and the sums are ours.
What to charge in your area
The national ranges are wide because markets are: This Old House puts structural engineers anywhere from $100 to $500 an hour, sometimes with travel time included (October 2026). The two public schedules show how far one firm can sit from another — Yamabe & Horn's proposed Kerman schedule tops out at $250 for its principal, the Lebanon schedule at $320 for its top engineer-scientist-specialist class, plus $7.50 an hour for project support costs. City and county council packets publish their consultants' rate schedules; read two or three from your own region before you set yours.
In the US, engineering is licensed state by state: NCEES — whose members are the engineering and surveying licensing boards of all 50 states — says only a licensed engineer can prepare, sign, seal and submit engineering drawings, and that the usual path is an accredited degree, the FE and PE exams and — in most states — four years of experience, with other paths in many states (read November 2026). Check your state board's rules before you offer stamped work, and confirm how you bill expenses and sales tax with your accountant.
Outside the US, treat the dollar figures as a shape, not a price: a ladder by grade built from pay, flat fees for defined jobs, a share of construction value on big builds. Check what firms in your own country publish.
Put your prices on your website
A price list — even “from” prices — answers a customer's first question before they pick up the phone, and it's the line an AI assistant can quote when someone asks what a structural engineer costs near them.
If you build your site with Zarla, tell the editor “add a pricing section: structural inspections from $300, beam calculations from $300, foundation repair plans from $800” and your prices go on the site, in a section you can edit any time.

Structural engineer cost: common questions
$100 to $500 an hour, and $300 to $1,000 for a foundation inspection, $600 on average (This Old House, October 2026). For residential work, HBG Civil puts the usual rate at $100 to $250 an hour and the flat-fee jobs — inspections, beam calculations, repair plans — at $300 to $2,500. The calculator above prices a job by type, by the hour or as a share of the build.
$100–$250 is the usual residential range, $300 or more for a senior principal on a complex case, and $75–$120 for junior staff under a PE's supervision (HBG Civil). On two public 2026 schedules, one California firm proposes $250 for its principal (Yamabe & Horn, for the City of Kerman), and another firm bills $135–$320 across its engineer-scientist-specialist classes (its schedule for the City of Lebanon, Oregon).
$300–$700 for a single-issue inspection, plus $150–$400 if you add soil testing, and $600–$1,500 for a fuller engineering assessment (HBG Civil). This Old House puts a foundation inspection at $300–$1,000, $600 on average, and says most take one to two hours (October 2026).
5%–15% of construction value is the usual band, rare below a $50,000 budget and standard on commercial-adjacent residential work above $250,000 (HBG Civil). Monograph's guidelines put MEP engineering at 5%–15% and civil and infrastructure work at about 6.8% for a $1–2 million project, 5.9% for $5–10 million and 5.4% above $20 million (October 2026).
From pay, with a multiplier. Yamabe & Horn's proposed 2026 schedule for the City of Kerman multiplies each employee's hourly pay by 1 plus 142.70% (65.02% fringe benefits plus 77.68% overhead), then by 1.10 for its fee — 2.67 in all — so $94.00 of pay bills $250.95, rounded to $250 (January 2026). Your own overhead sets your multiplier.
All the firms Zweig Group surveyed had raised their billing rates in the past three years, by 11% at the median (Monograph, October 2026), and Yamabe & Horn's proposed Kerman schedule builds in 3% each fiscal year. Whatever rise you choose, put it in your fee schedule so clients see it coming.
Yes — “inspections from $300” and a line on how you price bigger projects answer the first question before the call, and they're the figures an AI assistant can quote. On a Zarla site, tell the editor “add a pricing section” with your fees, and change them when your schedule does.
