How Much Does a Structural Engineer Cost?
Structural engineering fees depend on whether you need an inspection and letter, a small calculation such as a beam size, or full sealed drawings. Small residential tasks are usually a modest fixed fee; additions and commercial work cost more.
Common residential services and how they are priced
A structural inspection with a written letter (for a foundation crack, a sagging floor or a home sale contingency) is usually a fixed fee. Commonly quoted ranges run from a few hundred dollars to roughly a thousand dollars, depending on the region, the size of the house and how detailed the report must be.
Sizing a beam to remove a load-bearing wall, or designing a header, often costs a few hundred to a couple thousand dollars because the engineer must trace loads from the roof down to the foundation and may need a site visit. Full structural drawings for an addition, a second story or a custom home cost more and are often quoted as a fixed fee based on the square footage and complexity.
These are rough, commonly quoted ranges, not market data. Local quotes govern.
What makes structural work cost more
Unknown existing conditions are the biggest variable. If the engineer cannot see how the existing framing or foundation is built, they may need to open walls or make assumptions that require extra checks. Old houses with undocumented renovations take longer.
Other cost drivers include point loads that must be carried to new footings, steel beams and their connections, high wind or seismic regions, repair designs for damaged structures, and jurisdictions that require full calculations rather than a letter. Rush schedules and repeat site visits during construction also add cost.
How to keep the fee reasonable
Send clear photos, the address, any existing plans and a description of what you want to change before the visit. Ask whether the fee includes revisions after plan review and a final observation visit, which many building departments require for structural repairs.
Combine tasks into one visit when possible. If you are planning several changes, an engineer can evaluate them together for less than separate visits.
Frequently asked questions
Is a structural engineer worth it for a home purchase?
If an inspector flags foundation movement, framing damage or a large crack, a structural engineer's evaluation gives you a professional opinion and a repair scope to negotiate with.
Do I need a structural engineer to remove a wall?
If the wall is load-bearing, yes in most jurisdictions. The engineer specifies the beam, posts and footings.
Does the engineer's letter cover repair costs?
The letter describes the condition and the recommended repair. Costs come from contractor bids.
Will my insurance pay for a structural engineer?
Sometimes, as part of a covered claim evaluation. Ask your insurer before scheduling.
