Reinstatement fees vary by state and depend on how long your license has been inactive

The cost to reinstate a Professional Engineer (PE) license for washing (water and wastewater systems) is not a single national figure — each state sets its own fee. Most states charge between $100 and $400 to reinstate a lapsed PE license, but some charge more. The fee often depends on how many years have passed since your license expired and whether you need to renew your continuing education credits at the same time.

Before you pay any fee, contact your state's engineering licensing board directly. They can tell you the exact reinstatement cost for your state, what documents you need to submit, and whether you have any other requirements — such as proof of recent continuing education hours — before your license becomes active again.

Key Takeaways

  • Reinstatement fees range from roughly $100 to $400 depending on your state and how long your license has been inactive.
  • Your state's engineering licensing board sets the fee and the reinstatement process, so you must contact them directly for the exact amount.
  • Many states require you to complete continuing education hours before reinstatement, which may involve additional costs for courses.
  • Some states offer a grace period after expiration during which reinstatement is simpler and cheaper than full reapplication.

How state licensing boards determine reinstatement cost

Each state's Professional Engineer licensing board operates independently and sets its own fee schedule. Some states charge a flat reinstatement fee regardless of how long your license has been expired. Others charge more if your license has been inactive for a longer period — for example, California charges one amount if your license expired within the last five years and a higher amount if it expired longer ago.

A few states bundle the reinstatement fee with the renewal fee, meaning you pay one combined amount to bring your license current and keep it active for the next renewal cycle. Others charge reinstatement and renewal as separate transactions. The only way to know which applies to you is to look up your state's engineering board website or call them directly.

Continuing education requirements and their costs

Most states require PE licensees to complete a certain number of continuing education (CE) hours each renewal cycle — typically 30 to 40 hours over two years, though this varies. If your license has been expired, you may need to complete CE hours before reinstatement, or you may need to complete them when ready after reinstatement as part of your next renewal cycle.

CE courses are offered by universities, professional societies like the National Society of Professional Engineers (NSPE), and private training providers. Costs range widely — some courses cost $50 to $100, while comprehensive programs can run $300 or more. If reinstatement requires you to catch up on missed CE hours, budget for course fees on top of the reinstatement fee itself.

Grace periods and when reinstatement becomes more expensive

Some states offer a grace period after your license expires — usually 30 to 90 days — during which you can reinstate without penalty or at a reduced cost. If you miss the grace period, reinstatement becomes more complicated and expensive. You may have to pay a late fee, complete additional CE hours, or in some cases reapply from scratch, which costs significantly more than straightforward reinstatement.

Check your state's rules as soon as you realize your license has expired or is about to expire. Acting within the grace period can save you money and time.

Documents you will need to submit

Reinstatement typically requires less paperwork than an initial PE process, but you will still need to provide certain documents. Most states ask for a completed reinstatement form (available on the licensing board's website), proof of your current mailing address, and confirmation that you have completed any required continuing education hours.

Some states also require a brief statement explaining why your license lapsed and confirming that you are still competent to practice. If you have been out of the field for many years, your state may ask for additional information or may require you to pass a refresher exam. Ask your state board what documents to gather before you submit your reinstatement request.

How to find your state's exact reinstatement fee

The fastest way to learn the cost is to visit your state's Professional Engineer licensing board website and look for a fee schedule or reinstatement page. Most states post their current fees online. If you cannot find the information, call the board's main office — staff can tell you the fee over the phone and answer questions about what else you need to do.

When you contact them, have your PE license number ready and be prepared to tell them when your license expired. This helps the board staff give you accurate information about whether you fall within a grace period or whether additional requirements explore to your situation.

Reinstatement versus reapplication: which costs less

If your license has been expired for a very long time or if your state's reinstatement requirements are extensive, you may wonder whether it is cheaper to straightforward reapply from scratch. In almost all cases, reinstatement is less expensive than reapplication. Reapplication requires you to pay the full initial process fee (often $300 to $600), submit transcripts and work history documentation, and in many states pass the PE exam again.

Reinstatement, by contrast, assumes you already hold a valid PE license and just need to bring it current. The fee is lower, the paperwork is simpler, and you do not retake the exam. Only consider reapplication if your state's licensing board tells you that reinstatement is not an option for you — which is rare.

Frequently Asked Questions

Can I practice engineering while my reinstatement is being processed?

No. You cannot legally practice as a PE or use the PE title until your license is officially reinstated. Processing typically takes two to four weeks. If you need to practice before reinstatement is complete, ask your employer whether you can work under supervision or in a non-licensed capacity during that time.

Do I have to pay the reinstatement fee if my process is denied?

Most states do not refund reinstatement fees if your process is denied. However, denial is uncommon for reinstatement — the board is straightforward verifying that you meet basic requirements. Ask your state board what could cause a denial before you submit so you can address any issues first.

What if I cannot afford the reinstatement fee right now?

Some states offer payment plans or allow you to request a fee waiver based on financial hardship, though this is not universal. Contact your state's engineering board and ask whether they have a hardship policy. If not, you may need to wait until you can pay the full fee.

Does reinstatement cost the same as renewal?

Not always. Reinstatement and renewal fees are sometimes the same amount, but some states charge differently depending on whether you are bringing a lapsed license current or renewing an active one. Check your state's fee schedule to see the distinction.

How often do I have to reinstate, or is it a one-time payment?

Reinstatement is a one-time action that brings your license current. After that, you follow the normal renewal cycle for your state — typically every one or two years — and pay the regular renewal fee each time. You only reinstate again if your license lapses a second time.
