What changes the price
Scope, not ZIP code. The things that move a quote are the number of sheets, the number of disciplines, whether calculations and a report are required, how much information is missing at the start, and how fast you need it. We will tell you which of those is driving your number, and usually how to bring it down.
How engineering pricing works here
Every project gets one fixed price before any work starts. You send what you have, an engineer reviews the scope, and you receive a written quote with the price, the sheets included and the delivery date. If you approve it, that is the price you pay. It does not grow because the plan reviewer asks questions, and it does not change if the review takes an extra round. The only thing that changes a fixed fee is a change to the project itself, and even then you see the new price before any extra work begins.
This is different from the hourly billing many engineering firms still use. Hourly billing makes budgeting hard because nobody knows how many hours a project will take until it is finished. For the kind of residential and light commercial work we do every day, the scope is predictable enough to price up front, so the risk of overruns sits with us, not with you.
What sets the price
Engineering pricing depends on scope, not on where you live. These are the factors that move a quote up or down.
- Number of sheets. A single beam letter is one page; a new house can be twenty sheets across several disciplines.
- Disciplines. Structural only, or structural with mechanical, electrical, plumbing and civil.
- Calculations and reports. Some departments want a full calculation package or a stormwater report; others accept notes on the drawings.
- Starting information. Complete drawings and a survey take less time than a hand sketch and photos.
- Complexity. Long spans, steel, hillside sites, high-wind or seismic zones and unusual shapes take more engineering.
- Schedule. Standard turnaround is included; rush delivery is available on many scopes for an added fee.
Typical starting prices by project
These are starting points for common residential scopes. Your quote may be lower or higher depending on the factors above, and it is always confirmed in writing before work begins.
- Review and PE stamp of existing drawings for small residential work: from $249
- Engineered plans with a PE stamp, such as a beam design, deck plan, retaining wall or small addition: from $599
- Full approval support for larger or multi-discipline projects, with a dedicated project manager: from $1,999
- Solar structural letters and plan sets, MEP sheets and site plans are quoted to scope, often in the lower range for standard residential work
- Commercial tenant improvements and multi-discipline commercial projects are quoted individually after a short review of the space and the scope
What every price includes
A fixed fee covers the work needed to get your permit approved. That means the engineering design or review, the drawings and calculations the jurisdiction requires, the seal and signature of an engineer licensed in your state, the sealed PDF set ready for submission, responses to plan review comments and the revisions those comments require. Direct contact with the engineer doing the work is included too, so your questions get answered by someone who knows the project.
What is not included
Some items are separate because they involve other professionals or fees outside our control. Building department permit fees are paid directly to the city or county. Land surveys are performed by licensed surveyors on site. Geotechnical soil reports are prepared by geotechnical engineers when the project needs one. Site visits are quoted separately when a project requires an engineer on site. We tell you up front when any of these are needed, so there are no surprises later.
How payment works
After you approve the quote, you receive an invoice by email with payment instructions. Work starts once the invoice is settled, and the delivery date in the quote begins from that point. For larger projects, payment can be split into stages tied to milestones such as the preliminary design and the final sealed set. Contractors with regular work can set up a simple process for recurring scopes.
Fixed fee versus hourly: an example
Consider a kitchen remodel that removes a bearing wall. Under hourly billing, the design might take three hours, then the reviewer asks for a connection detail, then another question about the footing, and each step adds time to the invoice. Under a fixed fee, the beam, posts, footings, connection details and every reviewer response are covered by the original price. You know the cost before you sign the contract with your builder, and the builder knows the engineering will not hold up the schedule.
How to get the best price
- Send complete information at the start: drawings, address, photos and any comment letter
- Combine related scopes, such as structural and MEP for the same remodel, into one quote
- Ask about standard turnaround if your schedule allows it; rush delivery costs more
- Tell us if you already have a survey or soil report, so the design uses it
- For multiple similar projects, ask about consistent pricing for repeat scopes
Engineering pricing compared with the cost of delays
The real cost of engineering is rarely the fee itself. It is the cost of a rejected permit, a failed inspection or a crew waiting for an answer. A set that is drawn for plan review, sealed correctly and supported until approval saves weeks on a typical project. That is why we focus on getting the drawings right the first time and staying with the project until the permit is issued.
Getting your fixed price
Send your plans, photos, a survey or a sketch through the quote form, by email or by chat. An engineer reviews the scope and replies with a written fixed price and a delivery date, usually within the hour, seven days a week. There is no obligation, and nothing is billed until you approve the scope and the price.
Pricing by discipline
Structural engineering is priced by the number of members and connections to design, the foundation work and whether lateral design is needed. A single beam for a wall removal sits at the lower end; an addition with framing, foundation and bracing sits higher; a new home with a full structural set is quoted as a package.
MEP engineering is priced by discipline and size. A single electrical sheet with a load calculation for a service upgrade or an EV charger is a small scope. A coordinated mechanical, electrical and plumbing set for an addition, a restaurant or a tenant improvement is larger, and the quote lists each sheet.
Civil engineering is priced by site area, the grading complexity and whether a stormwater report or erosion control plan is required. A simple residential grading plan is a modest scope; a sloped lot with retaining walls, detention and utility design is quoted to match.
Architectural plans are priced by floor area and the sheets the project needs, from a floor plan for an interior remodel to a complete set for a new home.
How online delivery keeps costs down
Most residential permit work does not require an engineer to drive to the site. Drawings, photos and measurements give the engineer what is needed, and the sealed set is delivered as a PDF for online submission. Avoiding travel time, printing and office overhead lets us keep fees predictable and turnaround short. When a project genuinely needs a site visit, for example certain inspections or a structural assessment, we say so before quoting and include it as a separate line.
Pricing for contractors and repeat clients
Contractors, designers and investors who send regular work get consistent pricing for repeat scopes such as beam designs, deck plans, foundation repair letters and solar structural letters. That makes it easy to include engineering in your own quotes. Ask about setting up standard details and title blocks for your company so every new job moves faster.
Refunds and changes
If an engineer reviews your project and finds that the drawings cannot be sealed as submitted, you get a written list of what needs to change and a separate price to complete it before you pay for anything extra. If your project changes after the quote, for example a larger addition or an added discipline, we send a revised quote for approval before doing the extra work. You always know the price before the work happens.
Questions about a quote
If anything in a quote is unclear, ask. The engineer who prepared it explains what is included, why a scope costs what it does and whether there is a simpler path that meets the code. Sometimes the cheapest option is a different design, such as a dropped beam instead of a flush beam, and the engineer will tell you when that is the case.
Pricing examples by project size
Small scopes include a single beam for a wall removal, a structural letter for solar panels or rooftop equipment, a review and stamp of a deck plan, or a load calculation for a service upgrade. These are typically the lowest fixed fees and the fastest turnaround, often 48 hours once the information is complete.
Medium scopes include an addition or ADU with framing and foundation design, a garage conversion with structural and MEP sheets, a retaining wall with drainage, or a grading and drainage plan for a new driveway. These are quoted as one fixed fee covering every sheet the permit needs.
Larger scopes include a new home, a second story, a restaurant or tenant improvement with several disciplines, or a site with stormwater management. These come with a dedicated project manager who coordinates the disciplines and keeps your schedule on track, and the fee is still fixed before work begins.
Price transparency you can share
Every quote lists the sheets, the disciplines, the delivery date and the price on one page. You can forward it to your contractor, lender or business partner, and everyone sees the same scope. If anything needs to be added later, the change is quoted the same way and approved before work continues. That simple process is why many clients come back for their next project.
Questions about pricing
If you are comparing quotes, look at what is included. A low price that excludes calculations, plan review responses or revisions often costs more by the end of the project. Our pricing includes the work needed to get your permit approved, so the number you approve is the number you pay.
Every fixed fee is confirmed in writing before work begins, and the price you approve is the price on your invoice.

Pricing: common questions
Is the quote really fixed?
Yes, for the scope we agree in writing. If you later change what you are building, we requote that change before doing it. You are never billed for something you did not approve.
Do I pay before or after?
Work starts once the fee is settled, and you see the scope, the engineer and the delivery date before you pay anything.
Are revisions charged?
Revisions needed to satisfy the plan reviewer are included. Revisions because you have changed the design are quoted separately and fairly.
Do you offer contractor pricing?
Yes, see engineering for contractors for standing scopes and repeat-volume pricing.
