Structural Engineer Cost Factors
How much you’ll pay to hire a structural engineer in Portland, OR, depends on a variety of factors. Here’s a closer look at how your total breaks down.
Fee Structure
When hiring a structural engineer in Portland, you will pay per project, per hour, or per square foot. If your engineer charges by the project, they may either charge a flat fee or a percentage of the entire renovation cost or the cost to build your house. The type of billing depends on the professional and the exact scope of work requested.
A structural engineer’s fee typically includes necessary manhours, on-site design consultation with an engineer or architect, evaluation of your property’s structural integrity, and a findings report. Their fee does not include trip charges, general contractor fees, permitting fees, or actual project costs such as materials, labor, or post-construction cleanup fees.
| Price Structure | Average Cost |
|---|---|
| Per project (fee) | $3,000–$10,000 |
| Per project (%) | 1%–4% |
| Per hour | $110–$140 |
| Per square foot | $1–$10 |
Project Complexity
The cost of a structural engineer will also vary based on the complexity of your project. If you’re just building an add-on to your existing home, your engineer will have minimal work to do to ensure the addition is safe.
If you’re instead altering your roof structure, replacing standard beams with more supportive steel I-beams to open up your space, or removing load-bearing walls, your engineer will have more work to do and will charge more accordingly. Custom new construction projects are the most involved work for a structural engineer and will typically be the most expensive. Costs can also increase if you’re hiring an engineer for complex projects like assessing your foundation or your home’s structural integrity as part of an earthquake retrofit project.
Type of Inspection
When working with a structural engineer, an inspection is the first step—and may also be the only step, depending on why you’re hiring them. A structural engineer charges a flat fee for inspections, including checks during the sale of a home. The cost of a structural report averages $700, but prices can range from $400 to $1,000, depending on the size of your home and the complexity of your project.
Your structural engineer inspection cost will likely reach $1,000 to $1,500 if you’re having your professional investigate suspected foundation issues, including foundation cracks, bowing foundation walls, wavy rooflines, or sagging or squeaky floors.
Structural engineers in Portland are often hired to assess a home’s structural integrity to protect against potential earthquakes. Structural damage inspections allow your engineer to recommend necessary structural repairs to restore your home’s safety.
These are the average costs associated with common types of structural engineering inspections.
| Type of Inspection | Average Cost |
|---|---|
| Beams/joists/trusses | $250–$1,000 |
| Buying or selling a home | $400–$1,000 |
| Foundation damage | $400–$1,000 |
| Home remodel | $500–$1,500 |
| Load-bearing walls | $250–$1,000 |
| New construction | $300–$1,500 |
| Storm damage | $500–$1,200 |
Engineer Plans
Engineer plans are the drawings that detail your construction project, and in the case of new construction, they’re the plans that an architect and builder will work off of to construct your home safely.
The engineer plans themselves, and the process to produce them will cost you anywhere from $1,000 to $4,000, depending on the scope of the project. The cost can be much higher for more complex, large-scale projects, sometimes reaching 45% of the engineering budget.
It’s a good idea to budget an additional $300 to $700 for revisions in case you want to make changes after the first round of drafting. Additional revisions after that point will cost about the same amount.
Here are average prices for standard drawings that Portland homeowners might request from a structural engineer.
| Drawing Type | Average Cost |
|---|---|
| Commercial construction | $7,000–$80,000 |
| Home add-on or bump-out | $2,000–$6,000 |
| Major home renovation | $3,000–$8,000 |
| New construction | $4,000–$12,000+ |
| Outbuilding construction | $1,000–$8,000 |
Additional Structural Engineer Costs
Portland homeowners should consider additional costs when hiring a structural engineer. Here’s a look at some other expenses that can impact your project.
PE Stamp
In most cases, a professional engineer (PE) stamp is bundled into the total project cost, which includes drawings, designs, calculations, and permit-ready plans. However, if you have existing plans from an architect or designer and just need a PE stamp from a licensed structural engineer for obtaining project permits, expect to pay between $500 and $1,500 for them to review your plans.
How much you’ll pay depends on the level of review and calculations required, whether any revisions or updates are needed, your engineer’s rate, and your project’s complexity. The more involved the engineer needs to be, the higher the cost for their stamp.
Permits
You don’t need a permit to hire a structural engineer, but you’ll need one to carry out your construction plans after their work is complete. In the city of Portland, permit fees are calculated based on the estimated cost of your project and the type of permit you require.
As a general guideline, Portland building permits start at $134 and increase for higher-value projects. There is also a plan review fee of 65% of the building permit fee, and a state surcharge of 12% is also applied to building permit fees. If you require additional inspections, budget an extra $153 in reinspection fees. For example, a 2,000-square-foot new residential single-family permit has a Building Permit Residential fee of $1,431.
If you’re obtaining permits for a commercial construction project, fees may reach several thousand dollars, depending on your scope.
Can a Structural Engineer Add Value to Your Home?
Hiring a structural engineer doesn’t have a specific return on investment (ROI) itself—instead, your returns will depend on the type of project you’re completing after they’ve completed their services. For example, if you hire a structural engineer in Portland because you’re building a home addition, you may see an ROI of 20% to 50% on your project. If you’re hiring a structural engineer for a pre-purchase home inspection or for post-storm soil inspection, your ROI will be less significant.
