If you own, are buying, or are thinking about selling a manufactured home in California, there is a good chance you will eventually hear someone ask:
“Does the property have a 433A?”
If your response is, “A 433-what?” — you’re definitely not alone.
The HCD 433A is an important California document involving manufactured homes, and it can become especially important when you are trying to sell or refinance one. The good news is that a missing 433A doesn’t necessarily mean there is something wrong with the home. But depending on the property’s history and foundation, obtaining one can range from fairly straightforward to a much larger project.
Let’s break it down.
What Exactly Is a 433A?
The HCD 433A is officially called the Notice of Manufactured Home, Mobilehome, or Commercial Modular Installation on a Foundation System.
In simpler terms, it is the recorded document showing that a manufactured home has been installed on an approved foundation system and that the installation was inspected and approved by the appropriate enforcement agency.
Once the process is completed and the 433A is recorded with the County Recorder, the manufactured home is treated as a fixture and improvement to the underlying real property, rather than simply as personal property.
That’s a pretty big distinction.
Think about it this way: a manufactured home may physically look like it has been sitting in the same place for decades. It may have a driveway, landscaping, patios, utilities and everything else you would expect from a traditional home.
But legally, the question is:
Has the manufactured home actually been permanently attached to the real property?
The recorded 433A is an important part of establishing that answer in California.
Why Does a 433A Matter When Selling a Home?
This is often where homeowners first discover the issue.
A seller may have owned the property for years without ever thinking about a 433A. Then the property goes into escrow, the buyer obtains financing, and suddenly the lender, appraiser or title company starts asking questions about the manufactured home’s foundation and legal status.
Many mortgage programs require a manufactured home to be permanently attached and legally classified as real property. For example, Fannie Mae requires eligible manufactured homes to be attached to a permanent foundation and legally classified as real property.
Depending on the financing program, additional foundation documentation may also be required. FHA requirements, for example, can involve certification from a licensed professional engineer or registered architect that the foundation complies with HUD’s Permanent Foundations Guide for Manufactured Housing.
So when someone says, “We need the 433A,” what sounds like a small paperwork issue can sometimes become an important part of getting the transaction financed and closed.
Does Every Manufactured Home Already Have One?
No.
Some manufactured homes were properly installed and have a recorded 433A that simply needs to be located.
Others may have been installed years ago but have incomplete records.
And some homes may never have gone through the process necessary to have a 433A recorded.
That is why one of the first steps should be determining whether a 433A already exists before assuming that a new one needs to be obtained.
How Hard Is It to Get a 433A?
The answer is everyone’s favorite real estate answer:
It depends.
If the home is already installed on a compliant permanent foundation and the permitting and ownership records are in order, the process may be relatively manageable.
But if the foundation does not comply, permits were never completed, documentation is missing, there are title or lien issues, or unpermitted alterations have been made, getting everything corrected can become considerably more complicated.
California’s process requires more than simply filling out a form. Before installation on a qualifying foundation system, the appropriate building permit must be obtained, plans and specifications are required, and ownership and lien requirements must be addressed. After installation, the enforcement agency inspects the work and, when the requirements are satisfied, completes the process associated with the 433A and Certificate of Occupancy.
In other words:
You generally don’t just “apply for a 433A.” The property has to qualify for one.
What If the Home Isn’t on the Right Foundation?
This is where things can get more involved.
A contractor and, depending on the circumstances, an engineer or other qualified professional may need to evaluate the existing foundation system. If it doesn’t meet the applicable requirements, modifications or a new foundation system may be necessary before the installation can receive final approval.
California HCD also notes that installation work on manufactured homes requires the appropriate permits and that a C-47 General Manufactured Housing Contractor license is required for contractors performing certain manufactured-home installation work.
The difficulty and expense therefore depend heavily on what is already underneath the home and what records exist.
A property that already has an approved foundation but is missing documentation presents a very different situation from a home sitting on a foundation system that was never permitted or does not meet current requirements.
Can a Missing 433A Delay a Sale?
Absolutely.
And that’s one reason we recommend investigating the issue before the property is deep into escrow.
Imagine accepting an offer, opening escrow, completing inspections and getting close to the buyer’s loan approval — only to discover that the lender needs documentation concerning the manufactured home’s permanent foundation and real-property status.
Now everyone is working against a deadline.
Depending on what is discovered, there could be research, inspections, engineering, permitting, construction or recordation involved.
That isn’t something you want to discover a few days before closing.
Buying a Manufactured Home? Check Early.
Buyers should pay attention to the 433A too.
Before assuming a manufactured home will qualify for the financing you intend to use, your real estate agent and lender should help identify the property’s status early in the transaction.
Some important questions include:
- Is there a recorded 433A?
- Is the manufactured home legally part of the real property?
- Is the foundation acceptable for the buyer’s particular loan program?
- Are the home’s identifying information and property records consistent?
- Are there additions or alterations that could create additional requirements?
- Will an engineer’s foundation certification be required?
The answers can affect financing, title, appraisal and ultimately whether the transaction can close as planned.
So, How Long Does Getting a 433A Take?
There isn’t one universal timeline.
If everything is already compliant and the issue is primarily locating or completing documentation, the situation can be much simpler.
If engineering, plans, permits, foundation work, inspections or corrections are required, expect the process to take longer.
That’s why we don’t recommend guessing.

The Bottom Line
A 433A may look like just another government form, but for a California manufactured home it can represent something much more important: documentation that the home has been installed on a foundation system and made a fixture and improvement to the real property.
If you’re selling a manufactured home and aren’t sure whether you have a recorded 433A, don’t wait until you’re halfway through escrow to investigate.
And if you’re buying one, don’t assume that because the home has been sitting in the same place for 30 years that all of the necessary foundation and title documentation is already in place.
