Average Cost of Hiring a Structural Engineer

The average cost of hiring a structural engineer in the U.S. is around $475, but actual costs can vary significantly depending on the type of project, location, and the engineer’s expertise. Most people hiring can expect to pay between $450–$600, though prices can range from as low as $300–$400 for smaller inspections to $750–$4,500 or more for complex projects.

How are Structural Engineering Costs Calculated?

Structural engineers are highly specialised professionals who analyse and design safe building systems to withstand loads. They handle live loads (temporary weight, like people and furniture) and dead loads, permanent weight, such as:

Floors
Walls
Roofing

Their work involves calculations, drawings, inspections, and reports, all of which influence cost.

Common Pricing Models

Per Square Foot: $0.25–$2.00 (often for larger projects like new builds).

Per Hour: $100–$200 (standard for consultations or inspections).
Percentage of Total Construction Costs: 1%–10% (residential) or 0.5%–1.5% (commercial).
Flat Fee: Often used for specific services like inspections or drafting engineering plans.

Inspection Costs

Inspections are among the most frequent services requested.

Here’s a breakdown:

Full Home Inspection: $300–$750+ – Checks:
- Foundations
- Roofing
- Walls
- Joists
- Signs of water
- Structural damage
Foundation Inspection: $300–$600 – Evaluates basement/foundation walls for:
- Movement
- Cracks
- Safety issues
Load-Bearing Wall Inspection: $200–$600 – Essential if removing or altering a wall, ensuring proper support replacement.
Roof Inspection: $200–$600 – Assesses roof strength for snow loads, damage, or readiness for solar panels.
Chimney Inspection: $200–$500 (can reach $5,000 if extensive work is needed).

Cost per Project

Engineering Plans/Drawing:

Residential: $300–$2,500 per sheet.
Commercial: $1,000–$16,000+ per sheet.
Project Management: Around $20,000 for comprehensive oversight of complex builds.
Structural Reports: About $150 (often needed for real estate transactions).

While $475 is the average, costs are highly dependent on your project scope. Simple inspections stay at the lower end, but detailed plans for renovations, new builds, or commercial work can easily climb into the thousands.

Factors That Affect Structural Engineering Costs

Scope and Complexity of the Project

Structural engineering costs can fluctuate widely depending on the unique circumstances of each project. Understanding these factors helps in estimating fees accurately and avoiding unexpected expenses. Here are the primary elements that influence how much a structural engineer will charge:

Straightforward Tasks

Straightforward tasks such as inspecting a single crack or designing a beam, are less costly compared to larger, more involved projects like full-scale home extensions or new builds.

Complex projects often require extensive calculations, multiple site visits, and detailed drawings, which increase the overall fee.

Qualifications and Accreditation

Highly qualified professionals, such as chartered engineers in the UK or licensed engineers (PE) in the US, generally command higher rates. While this raises upfront costs, their credentials often ensure compliance with local building regulations, provide reassurance to lenders or insurers, and can be mandatory for planning approvals.

Type and Size of Firm

Smaller independent engineers or boutique consultancies typically have lower overheads and can offer more competitive pricing. Larger firms, while often providing a broader range of integrated services, may pass along higher operational costs in their fees.

Geographic Location

Urban and high-demand regions, such as London, New York, or San Francisco, tend to see higher professional rates, partly due to increased living and operating costs. Conversely, rural or less competitive areas may offer lower fees, though additional travel costs can arise if specialised engineers must be brought in.

Site Accessibility and Travel

Projects in remote or difficult-to-access areas can incur extra charges for travel time, fuel, or even overnight stays. Engaging a local structural engineer can not only reduce these costs but also provide an advantage in understanding:

Local soil conditions
Materials availability
Permitting requirements

Reports and Documentation

Not all structural engineering quotes include reports, calculations, and drawings by default. These documents are often essential for:

Building permits
Contractor guidance
Legal sign-off

A detailed structural report or stamped drawings may add to the final price if charged separately.

Urgency and Timeline

Fast-tracked projects or emergency inspections often cost more. If an engineer must rearrange their schedule, work outside regular business hours, or expedite deliverables, expect to pay a premium for prioritised service.

VAT or Sales Tax

Finally, factor in regional taxes: VAT in the UK or sales tax in certain US states may not be included in quoted fees. This can add anywhere from 10% to 20% to the final invoice if not clarified upfront.

6 Tips for Saving Money When Hiring a Structural Engineer

people working together - How Much Does It Cost To Hire A Structural Engineer

1. Bundle Services When Possible

If you're working on new construction, look into hiring a structural engineer who also offers architectural drawing services. Many firms provide discounts when you combine services, which can reduce overall costs while ensuring better coordination between design and structural planning.

2. Opt for Flat Fees on Smaller Projects

For smaller, well-defined tasks, like removing a load-bearing wall or replacing a beam, look for engineers who charge flat rates rather than hourly. Flat fees eliminate the risk of escalating costs if unexpected delays arise and provide more precise cost control from the outset.

3. Simplify and Standardise Your Design

Ask your architect to standardise building components such as beams, columns, and layouts. Repeated design elements reduce the amount of custom calculations and detailing your structural engineer must perform, lowering both engineering and construction costs.

4. Request Cost-Efficient Design Solutions

Work with an engineer who can propose designs that minimise material and labour needs while still achieving your goals. For example, using repetitive structural connections or aligning load paths efficiently can save on steel, timber, and labour hours while maintaining structural integrity.

5. Combine Inspections with Repairs

If you’re facing issues like foundation cracks or structural movement, choose an engineer who can perform both the assessment and necessary repairs. Many professionals offer small discounts when both services are carried out together, and it also streamlines the process.

6. Foster Collaboration Between Your Team

Select an engineer who is willing to work closely with your architect and contractor during the planning stages. Early coordination helps identify design conflicts or potential problems before construction begins, preventing costly changes and delays later on.

Experience Matters: How to Gauge a Structural Engineer's Expertise

When hiring a structural engineer for your project, experience is paramount. The more experience they have, the better the results will likely be. Of course, experience isn’t something that you can easily see.

This is why you’ll want to ask potential candidates a slew of different questions so that you can determine how experienced they are.

Here’s a list of questions that you can start with:

How many projects have you worked on?
What kind of projects have you been a part of?
How long have you been working as a residential structural engineer?

Aside from asking the questions listed above, you’ll also want to ask them for examples of the projects that they’ve worked on. This will help you determine whether they’ll be a good fit for your project.

Reputation Is Key: Don’t Skip the Research

While experience is essential, it’s also crucial that you hire a structural engineer with a good reputation. This is a great way to gauge the quality of their services, as it will be indicative of the quality of services that their previous clients received.

Be sure to check client reviews and testimonials so that you can get a good idea of the kind of service that you’ll be receiving. When reading reviews, be aware of fake reviews and testimonials that are there to mislead potential clients.

Interviewing a Structural Engineer: Get to Know Your Candidate

Have either a face-to-face or phone consultation to help you get a better sense of what they do and give you a chance to get to know one another. You should meet with multiple structural engineers to see who you click with and who has the skills to complete your project.

Cost of Hiring a Structural Engineer: Budgeting for Your Project

You’ll want to consider how everything will cost you. While this shouldn’t be the most significant factor, your budget will dictate what kinds of services you’ll have access to. With that being said, the costs of the services will be indicative of the type of service that you’re going to get.

While more affordable structural engineers are better suited for people who are operating on a tight budget, this isn’t something that you’ll want to skimp on if you have the resources to spare.
