Your loan officer just told you the loan needs a foundation certification from a licensed engineer. You’ve never needed one before, you don’t know who does them, and the closing date isn’t moving.
That’s how almost everyone finds out this exists. The good news is that picking the right engineer doesn’t take engineering knowledge. It takes a few questions on the first phone call, and knowing what the answers should sound like.
Start Here: It Has to Be a Licensed Professional Engineer
A foundation certification isn’t a home inspection. Your lender is asking for a letter signed and sealed by a licensed professional engineer (PE) stating that the foundation under the home meets HUD’s standard. A home inspector can tell you a lot about a house, but they can’t issue this letter, and an underwriter won’t accept one in its place.
The license also has to be in the state where the home sits. A PE licensed in Virginia can’t seal a letter for a home in North Carolina unless they’re licensed here too.
You don’t have to take anyone’s word for it. In North Carolina, every engineer and engineering firm is listed with the state board, and you can look one up in under a minute on the NC Board of Examiners for Engineers and Surveyors license verification page. A legitimate firm will give you both numbers without hesitating. Ours are on every letter: Person Engineering, Inc. is NC Firm License No. C-5329, and Travis Person, PE, is NC PE License No. 048738.
The Questions Worth Asking Before You Book
“Do you know the Permanent Foundations Guide for Manufactured Housing?”
This is the standard your home is being measured against. HUD published the Permanent Foundations Guide for Manufactured Housing, usually shortened to PFGMH, and it’s what lenders mean when they ask for a foundation certification, a PFGMH certification, or an engineer’s letter.
Any engineer doing this work should answer yes immediately and be able to tell you what it covers in a sentence or two. It’s a basic question, and most engineers who take on manufactured homes will pass it easily. That’s fine. It takes ten seconds, and the rare engineer who hesitates has just told you what you needed to know.
“Are additions included in the inspection?”
This is the question that changes the price.
Most manufactured homes on a loan file have something attached: a porch, a deck, a carport, an added room. When there’s an addition, the lender needs it inspected too (that’s the additions inspection), and the letter has to say the addition was inspected and doesn’t negatively affect the structure.
That means every addition, not only the ones someone points out. A small side stoop gets the same look as the front porch, because the letter covers everything attached to the home.
Some firms price the foundation and the additions as two separate inspections. The number you see advertised is the foundation number. The additions inspection gets added when it turns out you need one, which on most files is nearly always. If you don’t ask, you find out when the invoice changes, or worse, when the lender asks for an additions letter you were never sent.
So ask it plainly: if the home has a porch, a deck, or an addition, is that in the price you just quoted me?
“Have you certified manufactured homes specifically?”
A manufactured home isn’t built like a site-built house, and its foundation isn’t evaluated like one either. Plenty of very good engineers spend their careers on commercial buildings or custom homes and only occasionally see a manufactured home. That doesn’t make them bad engineers. It does mean they’re working outside what they see every week, and that’s when homes get failed for things the guidelines never asked for.
An engineer who does this work regularly will say so, and won’t mind you asking.
“When will I have the letter?”
Ask for a number of business days, and ask whether that’s from the inspection or from the day you book. Closing dates have very little give, and on some loans the lender sets its own deadline for the paperwork, with fees that add up fast once it passes.
A firm that tells you a slightly longer timeline and beats it is worth more than one that promises tomorrow and calls you on day four.
“If my lender has a question about the letter, who answers it?”
Underwriters follow up. They ask for a clarification, a corrected name, an additions statement, a copy sent to someone new. You want to know there’s a real office on the other end that will pick up and handle it while your loan is still open.
We’ve had clients come to us weeks after a certification was done elsewhere, because the lender asked for the additions inspection and nobody at the original firm could be reached. They ended up paying twice to save a little on the first quote.
What You’ll Need to Give the Engineer
Less than you’d think. To get on the schedule, we start with the property address and the name that goes on the letter, which is the borrower’s. Depending on the home, there may be a few follow-up questions, such as whether it’s occupied or vacant, so the visit goes smoothly. Your loan officer may reach out to check whether we can take the job, which is normal, but the letter is yours.
In most cases the borrower books and pays for the certification, since it’s their loan. It doesn’t have to be the borrower, though. Sometimes a seller, a family member, or the lender covers it. Whoever pays, the certification is still written for the borrower.
You don’t need to know what kind of foundation you have, whether the home has been modified, or which form the lender wants. That’s our job.
If the Report Comes Back Asking for Work
A certification can fail, and if it does, the letter should name a real structural or safety reason. That’s the point of having an engineer look at it.
Handrails are a common example. On a porch or deck, they’re often the first thing to rot or work loose, and a loose rail on a raised deck is a safety problem even when the deck itself is sound.
What a report shouldn’t do is ask for expensive work the guidelines don’t actually require on that foundation. If you get a report calling for thousands of dollars of repairs and something feels off, it’s fair to ask the engineer which part of the guidelines requires each item. A good engineer will answer that without getting defensive. If the answers don’t hold up, a second engineer’s opinion is a reasonable thing to get before you pay a contractor.

FAQ
Can a home inspector do a manufactured home foundation certification?
No. FHA, VA, and most conventional lenders require the foundation certification to come from a licensed professional engineer, signed and sealed. A home inspection is a different report for a different purpose, and an underwriter won’t accept it in place of the engineer’s letter.
How much does an engineer charge for a manufactured home foundation certification?
At Person Engineering it’s $500 flat in North Carolina, and that includes the additions inspection. Elsewhere, ask whether the quote includes porches, decks, and other additions. Some firms price those separately, which is why their advertised number can look lower.
Who pays for the foundation certification?
Typically the borrower, since it’s their loan and their name goes on the certification. It doesn’t have to be, though. Sometimes a seller, a family member, or the lender pays for it instead. A lender or loan officer often reaches out to check availability, but the borrower is usually the one who books and pays.
Can I use the foundation certification from the last time the home sold?
Sometimes. Two things usually decide it: how old the certification is, and whether the home has changed since. Most lenders will accept one from the last year, as long as nothing has been added or modified since, such as a new deck, porch, or heated addition. Each lender sets its own rules, and some want a new certification for every new buyer, so ask your loan officer before you order one.
How long does an engineer’s foundation certification take?
With us, 2–4 business days from the inspection. Timelines vary by firm, so ask for business days, and ask whether the clock starts at booking or at the inspection.
