Need a foundation certification
for your manufactured home?

Your lender wants a foundation certification. An engineer’s inspection decides whether you get one. Learn which rulebooks apply to your home, hire an engineer who checks only those, then check their report against them.

I have a report I need to check

Six steps to certification

  1. Step 1: Understand what your lender needs

    Pre-inspection: you and your lender or agent

    Why your lender asks. Your lender is betting on the house. Most home loans need it on a . It doesn’t mean the home can never move. It means the foundation meets the for support and anchoring, often ’s. Your lender wants proof, usually a certification from an engineer.

    Who signs it. Usually an engineer or architect licensed in the state where your home is. They sign and seal a certification saying your foundation meets the rulebooks your loan requires.

    HUD and . HUD’s guide covers how to support and anchor the home. FEMA’s rules cover how a home in a handles water. HUD’s guide itself points to FEMA for raised homes in flood areas. A report that ignores your flood zone deserves a second look.

    The foundation may need work. If it doesn’t meet the rulebooks, it needs upgrades before it can be certified. Some fixes are small, like extra tie-down straps. Some are big, like a new wall around the foundation. Knowing what’s actually required keeps you from paying for more.

    What you do

    • Find out if your home is in a flood zone. Step 3 checks your address for you.
    • Ask your lender which loan program you’re using, such as or conventional. It decides which rulebook applies (see step 3).

    What your lender or agent does

    • Asks for a foundation certification.
    • May not explain what it involves. If you have a real estate agent, they may help arrange it.

  2. Step 2: Find an engineer who certifies manufactured homes

    Pre-inspection: you

    Home inspector versus engineer. A home inspector checks a house’s condition for a buyer. They usually can’t certify a foundation. Some companies send a technician to measure. A reviews the results and signs. Either way, make sure a licensed engineer will sign the certification.

    What you do

    • Search the web for “manufactured home foundation certification” in your county. Look for engineers, not home inspectors.
    • Ask first whether they certify manufactured home foundations. Many don’t.
    • Have an agent? Ask who they’ve used. Then ask step 3’s questions anyway.
    • Look up the engineer’s license. How to look it up

    What the engineer does

    • Says up front whether they do manufactured homes.
    • Has a licensed engineer sign the certification, even if a technician does the visit.

  3. Step 3: Agree on the rulebooks before you hire Very important

    Pre-inspection: you and the engineer

    You’re hiring an engineer to answer one question: does your foundation meet the rulebooks that apply? There are up to four.

    1. HUD’s foundation guide, from 1996. FHA loans use it.
    2. The home maker’s installation instructions. Some conventional loans use these instead.
    3. State and local codes. Your state, county or town can add their own. How to check
    4. FEMA’s flood rules, if your home is in a flood zone.

    Your loan decides between the first two. Your home’s location decides the other two. Some engineers add of their own, beyond these, and you pay for those too.

    After the inspection, you get a pass or fail report. If it fails, the report lists the fixes, and you pay a contractor to make them. Some engineers charge extra for the list of required fixes.

    Questions you should ask

    • Which rulebooks will you check my home against? Check off the ones they name:
      Red flag: anything else, or “We can add any requirement we think is important.”
    • Does your price include the report, a second visit after any fixes, and the certification?
    • If the inspection fails the foundation, will the report say exactly what to fix, or do I pay extra for plans?
    • Will your report say which rulebook each required fix comes from?

    Print the questions

  4. Step 4: Get the inspection

    Inspection: you and the engineer or their technician

    Often a technician visits, measures, takes photos and leaves. There isn’t much for you to do. The work you did in step 3 is what protects you.

    What you do

    • Let them in, or have someone there.
    • Don’t agree to any work on the spot.

    What the engineer or technician does

    • Measures and photographs the foundation.
    • Tells you when the report will come.

  5. Step 5: Check the report Very important

    Post-inspection: you and the engineer

    What you check

    • Each required fix says which rulebook it comes from.
    • are labeled as recommendations.
    • Every required fix is described in the report, not held back for a paid plan.
    • Your flood zone is mentioned.
    • The report or certification is for your home, signed and sealed.
    • The seal shows a license number for the state where your home is. How to look it up

    What the engineer does

    • Can tell you which rulebook each required fix comes from, if you ask.
    • Explains the report in plain words when you ask.

    A good report says what failed, why, and which rulebook says so. Check each item.

  6. Step 6: Get your certification

    Post-inspection: you, the engineer and your lender

    Once any work is done, the engineer usually checks it again, then issues the certification.

    What you do

    • Do only the work the rulebooks require. You can get your own contractor quotes.
    • Send the certification to your lender and keep a copy.
    • Ask your lender whether they need anything else.

    What the engineer does

    • Corrects the certification if it has a mistake.
    • Answers your lender’s follow-up questions.
