Who Can Seal Your Plans? Engineer Requirements in Five States
You hired a good engineer. The plans look right. You submit them, and the reviewer sends the package back before anyone has looked at a single line of the design: not sealed by an engineer licensed in this state. Or worse, and more confusing: firm not registered.
Both rejections come from the same misunderstanding, and it is the single most expensive assumption in multi-state development. A professional engineering licence is not a national credential. Neither is your engineer's company.
Here is how it actually works in the five states we practise in, what each one demands, and the specific detail in each that catches people out.
Two licences, not one
Almost everyone understands the first requirement: the individual engineer who signs and seals your drawings must hold a licence in the state where the project will be built. A Texas PE cannot seal plans for a house in Florida because they are a Texas PE.
The second requirement is the one that stops projects, because almost nobody outside the profession knows it exists. In most states, the firm needs its own authorisation to offer engineering services there separate from any individual licence, with its own application, its own fee and its own renewal.
That means a correctly licensed engineer can produce a perfectly sealed drawing that a building department still rejects, because the company that released it was not registered in that state. The seal was never the problem.
Florida: no shortcuts in
Florida is the strictest of the five on the individual side, and people consistently get this wrong.
Florida does not license by reciprocity or comity. There is no arrangement where a licence from another state converts automatically into a Florida one. The Board's own position is blunt: Florida offers licensure through endorsement, which means meeting Florida's requirements not another state's.
Florida does recognise that you passed the FE and PE exams elsewhere. It does not accept that the rest of your qualifying criteria necessarily match. Applicants also sit Florida's Laws and Rules study guide and must score 90% or above.
On the firm side, Florida changed in October 2019. The old certificates of authorization, renewed every two years for a fee, were eliminated. Firms now register with the Board and must be qualified by a Florida-licensed professional engineer on staff. The registry covers out-of-state firms providing services on a temporary basis, so crossing the state line for one project does not exempt you.
Texas: the number has to be on the drawing
Texas requires firm registration under Board Rule 137.77: any firm offering engineering services to the public must be registered with the Board.
Then Texas adds something no other state on this list does, and it is the reason Texas submittals get bounced. Every engineering document released by a registered firm including preliminary documents must clearly indicate the firm name and registration number. On the sheet. Where a reviewer can see it.
The Board is explicit that this is a shared duty: the PE who signs and seals the document and the firm that releases it are both responsible for checking that the firm name and number appear on the work.
It is a formatting requirement, which is exactly why it gets missed. Nobody reviews a title block for a registration number when they are worried about drainage calculations.
Maryland: the words are prescribed
Maryland regulates the seal itself in unusual detail. It carries the pictorial device of the Great Seal of Maryland at its centre, surrounded by "State of Maryland" and "Professional Engineer", plus the licensee's name and licence number, at an overall diameter between 1-5/8 and 2 inches.
More consequentially, Maryland prescribes the certification wording that must appear in the title block. The engineer certifies that the documents were prepared or approved by them and that they are a duly licensed professional engineer under the laws of the State of Maryland, with the licence number and expiration date stated. The title block, certification, seal and signature must sit in close proximity to one another.
Maryland's Board also issues permits to the business entities through which engineering is practised, and restricts the name itself: an entity may not use the word "engineering" or its derivatives unless it regularly employs a licensed professional engineer.
North Carolina: who owns the firm matters
North Carolina requires firm licensure in addition to the individual professional's licence, and its conditions reach further into your company than any other state here.
Under N.C.G.S. 55B, the firm must be at least two-thirds owned by licensees. There must be at least one North Carolina licensee for each profession practised who is an officer, director and shareholder. Up to one third of the firm may be owned by non-licensed people, and they must be employees.
For an out-of-state company the sequence matters and it is not the obvious one. Corporations and LLCs formed after June 1969 must qualify in North Carolina as foreign Professional Corporations or Professional Limited Liability Companies. The application goes to the Board first, then to the Secretary of State, and the Secretary of State's documents come back to the Board before the firm licence is issued. Getting that order wrong costs weeks.
Qualifying as a foreign professional entity does not change how your firm is organised in its home state. It is an additional registration, not a restructuring.
Virginia: register the entity, and every office
Virginia requires any business entity offering or rendering professional services in the Commonwealth to register with the Board and to designate a responsible person for each professional service offered. The requirement sits at 18VAC10-20-627.
There is an ordering trap here too. An out-of-state professional limited liability company must first obtain a certificate of registration to conduct business in Virginia from the State Corporation Commission, and only then register with the Board.
And Virginia counts locations. If your business operates from more than one place, each branch office registers separately. A firm that opens a second office and assumes the original registration carries over is operating unregistered at the new address.
The five states side by side
Florida. Endorsement or examination, no comity or reciprocity. The firm registers with the Board and must be qualified by a Florida PE on staff. Temporary out-of-state work is covered too.
Texas. Texas PE licence plus firm registration under Board Rule 137.77. The firm name and registration number must appear on every document, preliminary ones included.
Maryland. Maryland PE licence with a prescribed seal and prescribed certification wording. The Board issues a permit to the business entity.
North Carolina. North Carolina PE licence plus a firm licence, with the firm at least two-thirds owned by licensees. Board first, Secretary of State second, Board again.
Virginia. Virginia PE licence plus entity registration under 18VAC10-20-627, with a designated responsible person. Every branch office registers separately.
What this means if you are building outside your home state
Your usual engineer may not be able to help you. A long relationship with a firm in one state is worth nothing at a counter in another if neither the engineer nor the firm is licensed there.
Ask before the design starts, not before the submittal. Firm registration can take weeks. Discovering the gap when the plans are finished means the drawings exist and cannot be used.
A sealed drawing is not proof of compliance. The seal covers the individual. It says nothing about whether the firm may legally release the work in that state.
Each state is a separate exercise. Nothing carries over. Five states means five individual licences and five firm authorisations.
Budget the ordering, not just the fees. North Carolina and Virginia both require steps in a specific sequence involving a second agency. The cost is time, not money.
Four questions to ask before you hire
Any competent firm will answer these in a sentence each. Hesitation is your answer.
Is the engineer who will seal my plans licensed in the state where my project is? Not the firm's principal the person whose seal goes on the sheet.
Is your firm registered or licensed to practise in that state, and what is the number? In Texas that number has to appear on the drawing anyway.
If not, how long will it take, and who pays for the wait?
Who is the designated responsible person for this state? Virginia requires one by regulation, and the question is revealing everywhere else.
Building in more than one state? Vasquez Civil is licensed and registered to practise in Florida, Texas, Maryland, North Carolina, and Virginia, which means one team, one set of drawings, and no gap between the engineer's seal and the firm's authority to release it. Tell us where your project is and we will tell you what it takes to get sealed plans there.
Frequently asked questions
Can an out-of-state engineer stamp my plans?
Only if that engineer holds a licence in the state where the project is located. A professional engineering licence is issued state by state and does not transfer automatically. In most states the engineer's firm also needs its own registration or licence to offer services there, which is a separate requirement from the individual licence.
Does Florida accept an engineering licence from another state?
Not by reciprocity or comity. Florida offers licensure through endorsement, which means the applicant must meet Florida's own requirements. Florida recognises that the FE and PE exams were passed elsewhere, but other criteria may differ, and applicants must also complete Florida's Laws and Rules study guide with a score of at least 90%.
Why was my Texas submittal rejected if the plans were sealed?
A common cause is the firm registration number. Texas requires that engineering documents released by a registered firm clearly show the firm name and registration number, including preliminary documents. Both the sealing engineer and the firm are responsible for checking it appears. The design can be correct and the package still incomplete.
Does my engineering company need its own licence?
In Florida, Texas, Maryland, North Carolina, and Virginia, yes the business entity needs its own registration, permit or licence to offer engineering services, separate from the individual engineer's licence. Requirements differ: North Carolina sets ownership conditions, and Virginia requires a designated responsible person and separate registration for each branch office.
How long does it take to get a firm registered in a new state?
It varies by state and by how the company is organised, and it is rarely instant. North Carolina and Virginia both involve a second agency in a set sequence, which adds time beyond the board's own review. Start the process before the design work, not when the plans are ready to submit.
Do I need separate plans for each state?
The design usually adapts rather than restarts, but the sealing, certification and title block requirements are state-specific. Maryland prescribes particular certification wording, Texas requires the firm registration number on the sheet, and each state requires a seal from an engineer licensed there. The drawings must be issued to satisfy the state where the project is built.
