Typical structural engineering fees

Structural engineering fees are charged as a flat fee, hourly rate, or percentage of construction costs, depending on the scope of work, site visits, drawings, and reports.

  • Home and foundation inspections are charged at a flat fee, with any additional time billed hourly.

  • Consultations are charged by the hour.

  • Home renovations and new house construction are charged as a percentage of the total construction budget. The architect's fee typically includes the structural engineer's fee.

  • Drawings and building plans are charged at an hourly rate or have a flat fee.

  • Project management is charged as a percentage of the total construction cost.

Engineering fees as a percentage of construction cost

Structural engineer fee percentages for residential projects are 1% to 5% of the total construction budget, depending on if it's a new house, extension, or renovation. Engineering fees for commercial construction projects are 0.5% to 2.5%.

Structural engineer fee percentage
Project Percentage fees Total cost for engineer
New house construction 1% – 3% $1,600 – $12,500
House renovation / remodel 1% – 5% $1,900 – $3,700
House extension / addition 1% – 5% $2,200 – $3,700
Commercial construction 0.5% – 2.5% $4,000 – $190,000+

Structural engineer consultation cost per hour

A structural engineer costs $100 to $220 per hour, depending on experience, location, and project complexity. Most structural engineers charge a flat fee for inspections and an hourly rate for a consultation or anything outside the project's original scope.

Structural engineer cost per square foot

Structural engineering costs $0.50 to $2.00 per square foot, depending on the project type, size, and complexity. Hourly rates and flat fees are more common than charging per square foot.

Structural engineer inspection and report cost

A structural engineer inspection costs $150 to $1,000, depending on the type and purpose. After inspecting the home, foundation, roof, or chimney, the structural engineer provides a report detailing the findings.

Structural engineer inspection cost
Type Inspection and report cost
Full home inspection $350 – $900
Foundation inspection $300 – $750
Load-bearing walls & beam calculation $250 – $1,000
Roof inspection $150 – $600
Chimney inspection $200 – $600

Structural engineer inspecting home
Structural engineer inspecting home

The engineer's report typically states:

  • If the home is structurally sound

  • If not, what repairs are needed to address the problem

  • A step-by-step plan for correcting the issue, if included in the fee

If the inspection is for new construction or a remodel, the report confirms whether the building contractor adhered to the design plans.

Structural engineer home inspection cost

A structural engineer home inspection costs $350 to $900 and takes 1.5 to 3 hours, depending on the home's size. During a house inspection, a structural engineer performs a visual inspection to confirm the building's structural integrity and then reports the findings.

  • A structural home inspection involves examining the home's load-bearing components, including the foundation, walls, beams, joists, columns, and posts.

  • Engineers check for shifting foundations, erosion, dry rot, and infestations.

Structural engineer foundation inspection cost

A structural engineer foundation inspection costs $300 to $750, depending on the home size and type. A structural engineer performs a visual evaluation to confirm the foundation is safe and intact. Hire a structural engineer to inspect cracks, bowing, or foundation shifting.

Load-bearing walls and beam calculation cost

Structural engineers charge $250 to $1,000 for a load-bearing wall analysis or $3,000+ when including drawing beam calculation plans. Prices are higher in areas with more building regulations and a higher cost of living.

Structural engineer roof inspection cost

A structural engineer roof inspection costs $150 to $600, depending on the home's location, size, and style. If the inspection uncovers problems, structural roof repair costs $1,000 to $3,000.

Chimney inspection or breast removal

chimney inspection costs $100 to $600 to identify structural issues. A Level 2 or 3 inspection is required if the chimney is leaning or has structural, fire, or weather damage. Chimney repair costs $2,000 to $4,000 to fix a leaning stack.

Removing a chimney breast wall typically requires an inspection from a structural engineer if the wall provides structural support. Removing the wall may require adding support beams.

Engineering design plans fees

Structural engineering plans cost $500 to $3,000 for an average house design or remodel or up to $12,000 for a large construction project. The architectural firm's design fee typically includes the structural engineer's plan.

Draftsperson structural drawings cost

Hiring a draftsperson costs $30 to $120 per hour to create structural drawings. Drafting house plans costs $700 to $1,500 for pre-drawn plans or $2,000 to $10,000 for custom house plans. A draftsperson creates technical drawings and new blueprints or transfers existing site plans into CAD blueprints.

PE engineering stamp cost

The PE engineer stamp cost is included in the architectural plan fee. A PE stamp confirms the design plans meet all code and safety standards. For legal and liability reasons, most engineers won't stamp plans that weren't created by them or another engineer working under their direct supervision.

Civil engineer charges for plans

A civil engineer charges $100 to $200 per hour. Civil engineers design and maintain large structures, such as airports, roads, infrastructure, water systems, and public buildings.

Mechanical engineer cost

A mechanical engineer costs $100 to $200 per hour. Mechanical engineers design systems that generate, distribute, or use energy—such as engines, refrigeration, and air-conditioning systems—along with tools and technologies to meet transportation, production, and health care needs.

Structural Engineer FAQs

What does a structural engineer do?

A structural engineer evaluates the home's structural integrity during the design and construction process, inspects existing homes for structural issues, and draws up plans to fix those issues.

  • Design – A structural engineer works with the architect and building contractor to confirm the home's structural elements can withstand forces like gravity, pressure from the surrounding earth, and severe weather.

  • Construction – Structural engineers review site and soil conditions to determine the best structural support and materials for the building's design.

  • Renovation – A structural engineer evaluates remodeling design plans to ensure the changes will not harm the home's structural integrity.

  • Inspection – Structural engineers inspect existing homes, foundations, roofs, and retaining walls to identify structural issues that may cause a collapse, then create plans to correct the problem.

When to call and hire a structural engineer

Hire a structural engineer for any project that may affect the home's stability or structural integrity, such as:

  • Buying a home

  • A home addition or renovation

  • Moving or removing walls or a chimney breast

  • Foundation cracks, upheaval, sinking, or bowing walls

  • Structural movement, including unusual settlement, sloped floors, or cracks

  • Drainage issues on your property

  • Structural damage from a storm, flood, or earthquake

  • Solar panel or solar water heater installation

  • Retaining wall problems

Do I need an architect, home inspector, or structural engineer?

An architect costs $100 to $250 per hour or $5,000 to $60,000 for a full house design. Architects and structural engineers often work together to design a home, but their responsibilities differ.

  • An architect designs the home's aesthetic, spatial, functional, and technical aspects.

  • A structural engineer specializes in the home's strength, safety, durability, load-bearing elements, and structural integrity.

home inspection costs $250 to $400. A home inspector evaluates the home's structure and electrical, plumbing, and HVAC systems, typically for a real estate transaction.

How long does a structural engineer report take?

A structural engineer takes 1 to 10 days to deliver a report after inspecting, depending on if the inspection uncovered any problems. Most structural home inspection reports for real estate transactions are delivered within 24 hours.

How much do structural engineers make?

Structural engineers make $55,000 to $110,000 per year, depending on experience and location.
