About Residential PE — Licensed U.S. Engineering, Delivered Online
Residential PE exists to solve one specific problem: getting a competent, properly licensed professional engineer onto a project quickly, at a price that makes sense, anywhere in the United States.
For a homeowner adding a room, a contractor pricing a job, or a developer entitling a parcel, the engineering is rarely the hard part. Finding an engineer who answers the phone, understands the local code, quotes a firm number and turns work around in days rather than weeks — that is the hard part. We built the practice around fixing it.

How a Fully Online Engineering Practice Actually Works
There is nothing unusual about engineering being delivered remotely — drawings have been produced digitally for thirty years. What matters is who seals them and whether that seal is valid where you are building.
Licensed in Your State, Not Ours
A professional engineer seal is only valid in the state where the engineer holds an active licence. Every project is matched to an engineer licensed in the state where it will be permitted — and we tell you who that engineer is before you commit.
A Network, Not a Single Office
No individual holds licences in all fifty states, and any firm claiming otherwise should be treated with suspicion. We work through a network of licensed professional engineers so the right licence type is always available for your jurisdiction.
Independent Review Before Sealing
Design and review are separate steps performed by different people. Nothing is sealed on the strength of the person who drew it saying it looks right.
Services Delivered Fully Online
Consultation, drawing exchange, review comments and sealed delivery all happen digitally. That is what makes 48-to-72-hour turnaround possible without cutting the review step.
Jurisdiction Research Comes First
Before design begins we confirm the adopted code edition, the local amendments and the submittal checklist for your address. Code adoption varies enormously between states and even between neighbouring cities.
Written Scope, Fixed Fee
Every engagement starts with a written sheet list and one fixed fee. If we cannot define the scope clearly enough to price it, we say so rather than quoting a number we will have to revise.
Four Disciplines, One Coordinated Submittal
Most permit packages need more than one discipline. Keeping them together is the single most effective way to avoid the coordination errors that cause the majority of plan-review rejections.
Structural Engineering
Framing, foundations, retaining walls and lateral systems with full ASCE 7 load calculations — sealed and submittal-ready.
Civil & Site Engineering
Site plans, grading and earthwork, drainage and stormwater, utilities, access and paving for residential and commercial development.
MEP Engineering
HVAC, electrical and plumbing design with Manual J, NEC and fixture-unit calculations plus energy compliance documentation.
Review & PE Stamp
Technical review of drawings you already have, written comments, corrections where needed, and the engineer seal for your state.
The Standards We Hold Ourselves To
Engineering carries legal and professional obligations that marketing language tends to gloss over. We would rather be explicit about ours, because it is the reason our work holds up when a reviewer, an insurer or a lawyer looks closely at it.
- A seal is only ever applied after a genuine technical review by the engineer of record
- We name the engineer of record before you pay, not after
- We decline work we cannot make compliant, and say why
- We do not backdate seals, signatures or dates under any circumstance
- We do not certify work as designed beforehand when it was built first
- Client drawings, surveys and site data are never resold or published
- Where a project needs a discipline or study we do not provide, we say so
- If we get something wrong, we correct it at our cost
Why Clients Stay
Most of our work now comes from repeat clients and referrals — contractors and architects who used us once on a tight permit deadline and kept coming back. The pattern is consistent: what earns the second project is not the price, it is that the first set passed review without a correction letter.
How We Protect You Before You Spend a Dollar
Engineering is bought on trust long before it is bought on price. These are the commitments every Residential PE engagement carries, in writing, from the first message.
Free Quote, One Fixed Fee
Consultations and quotes cost nothing. You receive one written fixed fee against a written sheet list — no hourly billing, no surprise add-ons.
A Named Engineer of Record
Every drawing is sealed by a professional engineer holding an active licence in your project’s state, and we confirm who that engineer is before you commit.
Revisions Until Approval
If the plan reviewer returns comments, we revise the sealed drawings and respond as part of the original fee — never as a change order.
Your Documents Stay Private
Drawings, surveys and site information are used only to engineer your project. They are never resold, published or used as portfolio material without consent.
48–72 Hour Turnaround
Most standard packages are sealed and returned within two to three business days, so engineering is never the reason a permit slips.

Questions About Working With Us
Who actually seals my drawings?
A professional engineer holding an active licence in the state where your project will be permitted. We name that engineer before you commit, because a seal from an engineer licensed elsewhere is not valid for your permit. Some states add requirements — Illinois needs a Structural Engineer licence for structural work, Arizona does not grant reciprocity — and we match the project accordingly.
Are you a real engineering firm?
Yes. Residential PE operates as a professional engineering services practice delivering fully online, working through licensed professional engineers across the United States. Our published business entity is DBKAY SALES LLC, 13 Westwood Dr, Salem, Missouri 65560-2472. The engineer of record for your specific project, and their licence, is confirmed to you in writing before work begins.
How can you cover all 50 states?
By working through a network of licensed engineers rather than relying on one person’s licences. No individual engineer is licensed in all fifty states, and a firm that claims otherwise is worth questioning. We match each project to an engineer holding the right licence type in the right state.
What does a project cost?
We quote a fixed fee per project against a written sheet list, rather than billing hourly. The fee depends on scope, discipline and your jurisdiction’s submittal requirements. Quotes are free, carry no obligation and are usually returned the same business day — see our pricing page.
How quickly do you respond?
Live chat is typically answered within minutes during working hours, and quotes usually come back the same business day. Most standard sealed packages are delivered within 48 to 72 hours of receiving complete information.
What happens if my permit is rejected?
We respond to plan-review comments and revise the sealed drawings as part of the original engagement, not as a change order. The engineer of record stays on your project until the permit is issued.
Do you work with homeowners, or only professionals?
Both. A large share of our work is homeowners and small contractors dealing with a building department for the first time, and we explain what is required in plain language rather than assuming you already know. Architects, developers and builders use us for the same reason — speed and a set that passes first time.
How do I get started?
Send the project address, whatever drawings or sketches you have, and any comments the building department has already issued. That is enough for us to confirm scope and return a fixed-fee quote. You can use the quote form or open the live chat and talk to an engineer directly.
