Structural Engineer Cost Factors 

Boston, Massachusetts, homeowners can expect costs to vary based on fee structure, project complexity, inspection type, and required plans, especially in older buildings where evaluating signs of structural damage often demands more time and expertise.

Fee Structure

When hiring a structural engineer in Boston, 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 a house. The type of billing depends on the professional and the exact scope of work requested.

Price StructureAverage Cost
Per project (fee)$3,000–$10,000
Per project (%)1%–8%
Per hour$145–$175
Per square foot$1.50–$6

Project Complexity

The cost of a structural engineer for a home inspection 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 and will be the most expensive.

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 in Boston charges $750 to $1,300 for a standard structural inspection, with most full structural reports landing $900 to $1,500, depending on home size, age, and complexity.

Your structural engineer inspection cost will likely reach $1,600 or more if you’re having your professional perform a foundation inspection for foundational cracks, bowing foundation walls, wavy rooflines, or sagging or squeaky floors.

Type of InspectionAverage Cost
Beams/joists/trusses$450–$700
Buying or selling a home$800–$1,200
Foundation damage$700–$1,500
Home remodel$900–$2,000
Load-bearing walls$450–$800
New construction$600–$1,100
Storm damage$700–$1,500

Engineer Plans

Engineer plans are the drawings that detail the 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 $6,000, 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 the same amount.

Below, we've included some average pricing for standard drawings you might request from a structural engineer:

Drawing TypeAverage Cost
Commercial construction$7,000–$120,000
Home add-on or bump-out$2,500–$7,000
Major home renovation$3,000–$8,000
New construction$3,000–$12,000
Outbuilding construction$1,000–$10,000

Additional Structural Engineer Costs

In Boston, Massachusetts, additional structural engineering expenses often stem from local labor rates, permitting expectations, and the level of documentation required for older homes and tightly regulated neighborhoods. Understanding these extra costs helps you budget more accurately for complex or historic Boston properties.

Labor

Labor rates in the city range from $145 to $200 per hour, but costs climb when engineers must evaluate aging brick foundations, tight South End basements, or difficult third-floor walkups. A professional structural engineer inspection in Boston may cost $200 to $400 more when additional onsite time, advanced testing, or return visits are required.

PE Stamps

A standard PE stamp in Boston costs $150 to $400, but the price rises to $500 to $1,000 for stamped calculations involving load-bearing walls, multi-unit conversions, or major structural changes. Historic-district permits can also trigger added stamp fees if the city requires multiple revisions or resubmittals.

Permits

Boston homeowners don’t pay permit fees for a structural engineer’s inspection or stamped plans alone, but they do pay permit fees when the engineer’s findings lead to structural work. Any modification, such as removing a load-bearing wall, reinforcing framing, or repairing a foundation, requires a building permit from Boston ISD, with fees ranging from $50 to $200 or more for major structural work.

Taxes

Massachusetts doesn’t charge sales tax on structural engineering services, so Boston homeowners won’t pay tax on inspections, reports, or PE-stamped plans. However, the state does apply its 6.25% sales tax to construction materials used in the structural work itself, such as lumber, steel beams, connectors, or concrete, once the project moves from engineering into physical repairs or modifications.

In most cases, this tax is handled by your contractor as part of the materials purchase rather than being paid directly by the homeowner. 

Tipping

Tipping isn’t customary, but some Boston homeowners offer $20 to $50 when engineers spend extra time navigating cramped basements, steep staircases, or snow-season access issues. For extensive, multi-hour assessments on older homes, gratuities occasionally reach $75 to $100, though they remain entirely optional.

Can a Structural Engineer Add Value to Your Home?

Hiring a structural engineer doesn’t create a direct return on investment (ROI) on its own—your ROI depends on the project their expertise supports. In Boston, Massachusetts, projects such as a home addition can contribute to an overall project ROI of 20% to 50%, especially in older homes where added space and improved layouts are highly valued. If you’re hiring a structural engineer for a pre-purchase inspection or to evaluate storm-related foundation issues, the financial return is less direct, though their assessment can help you avoid costly surprises during negotiations.
