How much does a structural engineer cost?
A residential structural engineer often costs $350 - $800 for a basic visit or consultation, about $100 - $220 per hour, and $500 - $3,000 for residential plans, drawings, or written recommendations.
The right scope depends on why you need the engineer: removing a wall, diagnosing foundation movement, adding a second story, repairing storm damage, getting a permit, or giving a contractor a stamped detail to build from.

Before calling a structural engineer
- Photograph the issue from several distances and include a ruler, level, or tape measure where useful.
- Write down when the issue appeared, whether it is growing, and whether water, pests, tree roots, or recent remodeling may be involved.
- Ask the building department whether a stamped engineer letter is required for your planned work.
- If a contractor recommended a major repair, ask whether the engineer is independent or tied to the repair company.

Use this before you call a structural engineer, so you know what to ask and what to avoid.
Call a pro when…
- A wall, beam, roof, foundation, floor joist, stair opening, or exterior opening may change
- A foundation, basement wall, retaining wall, deck, balcony, or porch shows movement
- A permit reviewer asks for stamped structural details
- The repair quote is expensive and you want independent diagnosis
- Storm, fire, vehicle impact, or water damage may have compromised structure
Repair or replace?
A contractor can often repair a known issue, but an engineer helps define the right repair when load paths, foundations, movement, or permit requirements are unclear. On expensive structural work, the engineer fee can prevent the wrong repair from being sold as the only option.

Related questions
Is a structural engineer different from an architect?
Yes. An architect focuses on design, layout, code coordination, and drawings. A structural engineer calculates loads, designs beams or structural details, and may stamp structural drawings or letters.
Do I need an engineer to remove a wall?
You should treat any uncertain wall as structural until verified. If the wall is load-bearing, an engineer can size the beam, posts, footings, and connections before a contractor prices the work.
Can a foundation contractor provide the engineer?
Some can, but for major foundation work it is often worth getting an independent engineer first, especially if several repair methods are possible.
