"These guys did a fantastic job. They arrived on time, communicated with me as to what they were doing and finished when they said they would. The ceiling in my home has a rough transition to the wall, but they were able to make the paint line perfectly crisp and straight. My wife was very happy about that I would definitely recommend."

"I was looking for someone to handle blueprints and engineering for a home in the Florida Keys. Having built homes before, I’m familiar with the process and already had some sketches with a few changes I wanted to make. I found Evolution Drafting online, and Kristine walked me through everything clearly. Lindsey was assigned to my project after a quick introduction and a follow up she was AMAZING to say the least! The initial drawings were excellent, and any changes I requested were completed within days. Compared to another project that took nearly a year, this was incredibly fast and detailed. My wife and I are very impressed. I highly recommend Evolution Drafting LLC—ask for Lindsey on your project. Truly top shelf!!"
No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.
Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.
The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:
Do you have experience working in my specific area?
Do you have professional indemnity insurance?
What will your structural report cover?
Do you charge a flat fee for a structural report or by the hour?
How long have you been in business?
Do you have a list of customer references?
Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.
Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
