What Is California Form HCD 433A?
HCD 433A is an official California form that documents a manufactured home's installation on a qualifying permanent foundation system.
Form 433A, officially the "Manufactured Home Installation on a Foundation System" certification, is used when a manufactured home is installed on a permanent foundation that meets HCD's requirements. The form documents that the installation qualifies under the applicable standards. It is an HCD document associated with a specific category of installation — not a form a contractor produces on its own.
Because 433A relates to a qualifying permanent foundation, it does not apply to every manufactured home. Many homes rest on support systems that do not involve a 433A, and that is perfectly normal. The form becomes relevant only when an installation meets the specific requirements that call for it.
When HCD 433A May Apply to a Huntington Beach Manufactured Home
433A applies to a specific category of installation. Understanding when it applies — and when it does not — prevents unnecessary confusion.
A 433A may apply when a manufactured home is placed on a permanent foundation system that meets HCD's qualifying standards. This is distinct from a home on conventional piers, blocks, or stands that do not qualify as a permanent foundation under the applicable rules. For Huntington Beach owners, the question is whether a given installation falls into the qualifying category — and most routine installations do not.
Importantly, a 433A is not something a homeowner or contractor can simply choose to create. It depends on an installation that meets specific requirements and follows HCD's process. If a home does not have a 433A, that does not mean the home is defective or improperly installed — it may simply not fall under the category the form covers.
Permanent Foundation Installations and Documentation
A qualifying permanent foundation installation involves specific design and documentation requirements that go beyond ordinary support work.
Where a 433A applies, the installation typically involves an engineered foundation system, inspections, and documentation that follows HCD's process. The work may require engineering input, permits, and county recording. This is a more involved category than routine leveling or pier adjustment, and the documentation reflects that higher standard.
Owners considering a permanent foundation installation should understand that the process is distinct from ordinary repair work. It involves design, approval, and documentation steps that take time and coordination with qualified professionals and the relevant authorities. Confirming the requirements with HCD before beginning is essential.
HCD 433A Versus Routine Mobile Home Re-Leveling
One of the most common points of confusion is the difference between 433A and routine re-leveling. They are not the same thing.
Routine re-leveling
Adjusts the existing support system to restore even alignment. It does not require or produce a 433A, and it does not change the home's foundation classification.
433A installation
Documents a qualifying permanent foundation installation that meets HCD's specific standards. It is a distinct category involving engineered design and formal documentation.
Why the difference matters
Owners sometimes assume leveling work will generate a 433A or change their home's status. It will not. The two are separate categories of work.
When 433A is actually relevant
433A becomes relevant only when an installation meets the qualifying permanent foundation requirements — not during ordinary maintenance or adjustment.
Permits, Inspections and County Recording
Where a 433A applies, the process involves permits, inspections, and county recording — steps that are separate from the foundation work itself.
A qualifying permanent foundation installation typically requires permits and inspections under the applicable authority, and the 433A documentation is recorded with the county recorder in the county where the property is located. These steps follow HCD's process and depend on the documentation being complete and consistent with the applicable standards.
Recording is a formal step that makes the foundation documentation part of the property's public records. The specifics of the recording process, including fees and requirements, are set by the county recorder's office and HCD. Owners should confirm the current process rather than assuming a particular sequence.
Registration, Titling and Foundation Records
A 433A can interact with how a manufactured home is classified for title and tax purposes, but it is not the same as a title document.
Because a 433A documents a qualifying permanent foundation, it can be relevant to whether a manufactured home is treated as personal property or real property for certain purposes. That classification can affect taxation and how the home is financed or insured. However, the 433A itself is a foundation documentation form, not a title instrument, and its effect depends on HCD's requirements and the recording process.
Owners should not assume that obtaining or recording a 433A guarantees particular financing, insurance, tax, or resale outcomes. Those depend on lenders, insurers, tax authorities, and buyers, each applying their own criteria. Questions about title classification are best directed to HCD's registration and titling program.
Finding Existing HCD 433A Documentation
Owners researching a home's history can look for existing 433A documentation through official records.
Existing 433A documentation may be found through HCD's registration and titling records or through the county recorder's office where the property is located. A title search or records request can help determine whether a 433A is on file for a particular property. If no 433A exists, that may simply mean the home was not installed on a qualifying permanent foundation — not that anything is wrong.

Questions Before Modifying a Manufactured Home Foundation
Before any foundation modification, a few questions help clarify whether 433A is even relevant to the project.
Is the home currently on a qualifying permanent foundation?
Does the planned work change the foundation classification?
Is the work routine leveling or a permanent foundation installation?
What permits and inspections does the authority require?
Will the work need engineering input?
What documentation will the project produce or require?
