Manufactured Home Installation

Setting the home

Installation has its own federal standard, separate from the build

The code that governs how a manufactured home is built is not the code that governs how it gets set on your site. Construction runs under 24 CFR Part 3280. Installation runs under 24 CFR Part 3285, the Model Installation Standards, which provide minimum requirements for the initial installation of new manufactured homes in accordance with section 605 of the Act, 42 U.S.C. 5404¹.

There is a second route, and it is the one most installations actually follow. A manufacturer's own installation instructions are deemed to comply with the Model Installation Standards, provided they meet or exceed the minimum requirements of those standards and do not take the home out of compliance with the Manufactured Home Construction and Safety Standards at 24 CFR Part 3280¹. So the manufacturer's manual is the working document on site, and Part 3285 is the floor it has to clear.

HUD lists regulating installation among its own program functions, alongside enforcing the standards directly and through state agencies, inspecting factories and retailer lots, administering dispute resolution and authorizing the certification label². It identifies Part 3285 for model installation standards and Part 3286 for the installation program².

Six things that govern the set

Installation is where the federal code, the manufacturer's manual and your specific site all have to line up.

The Model Installation Standards

Part 3285 provides minimum requirements for the initial installation of new manufactured homes, in accordance with section 605 of the Act at 42 U.S.C. 5404¹. It sets the federal floor for the set, and it applies to new homes being installed for the first time rather than to later moves.

The manufacturer's instructions

The manufacturer's own installation instructions are deemed to comply with the Model Installation Standards, provided they meet or exceed those minimum requirements and do not take the home out of compliance with the construction and safety standards at 24 CFR Part 3280¹. Get a copy and keep it.

The installation program

Part 3285 does not stand alone. HUD identifies Part 3286 as the installation program, alongside Part 3280 for construction and safety standards and Part 3282 for procedural and enforcement regulations². HUD describes regulating installation as one of its direct program functions².

Foundation and utilities

The federal definition of a manufactured home describes a structure built on a permanent chassis and designed to be used as a dwelling with or without a permanent foundation when connected to the required utilities³. Foundation choice is a real decision at the set, and it is closely tied to how the home ends up titled⁴.

Matching the design zones to the site

The home was engineered for one wind zone and one roof load zone, and the data plate must reference both, with duplicates of the maps from section 3280.305(c)³. Confirm the zones on the plate suit the site before the home leaves the lot, not after it is sitting on piers.

Attached structures

The data plate must carry one of two statements about whether the home IS or IS NOT designed to accommodate the loads imposed by an attached accessory building or structure³. That line decides whether a carport, attached porch or add-on room is possible, and it is easier to read before the set than after.

Governing installation standard24 CFR Part 3285

Published national installation costNone

What does it cost?

No federal agency publishes what installation costs. Part 3285 governs how the work must be done¹ and HUD regulates installation as a program function², but neither publishes a price. The same is true for transport and set, site preparation, foundation work, utility connections and permits. This is the second largest thing a manufactured home buyer pays for and it has no citable national figure, so this guide gives none.

What is published is the home itself. The Census Bureau's Manufactured Housing Survey puts the 2025 average sales price of a new manufactured home at $127,200, with single-section homes at $85,600 and double-section at $157,100⁵. That is the home as sold and it excludes every installation item listed above. Get itemized written quotes locally, and treat any national installed-cost range you see as an estimate with no survey behind it.

The installation requirements come from 24 CFR Parts 3285 and 3280 as of August 2026 and from HUD's program description. The price is Census Manufactured Housing Survey 2025 data for the home only, excluding transport, site work, foundation, utilities, permits and installation.

Hiring

How to hire for a manufactured home set

1

Who does the work

HUD regulates installation and administers dispute resolution as part of its manufactured housing program, and identifies Part 3285 for the model standards and Part 3286 for the installation program². On site, the crew works to the manufacturer's installation instructions, which are deemed to comply with Part 3285 if they meet or exceed its minimum requirements¹.

2

What pros will ask

Site access for the transport, the foundation type, and how utilities will be brought in, since the federal definition contemplates a home used as a dwelling with or without a permanent foundation when connected to the required utilities³. Expect a question about titling too, because whether you own the land drives whether the home is personal property or real estate⁴.

3

What to check before signing

Ask for the manufacturer's installation instructions before work starts and confirm the crew is working to them¹. Read the data plate near the electrical panel and check the wind zone and roof load zone against the site³. Then confirm in writing whether site preparation, utility connections and permits are inside the quoted scope, since nothing published tells you what they should cost.

Manufactured home installation questions, answered straight

Which rules govern how my home is installed?

Two documents, working together. The federal floor is 24 CFR Part 3285, the Model Installation Standards, which provide minimum requirements for the initial installation of new manufactured homes in accordance with section 605 of the Act, 42 U.S.C. 5404¹. The working document on site is usually the manufacturer's own installation instructions, which are deemed to comply with Part 3285 provided they meet or exceed its minimums and do not take the home out of compliance with 24 CFR Part 3280¹.

Does a manufactured home need a permanent foundation?

The federal definition does not require one. It describes a structure built on a permanent chassis and designed to be used as a dwelling with or without a permanent foundation when connected to the required utilities³. What the foundation decision does affect is the paperwork. Whether the homeowner owns the underlying land plays a key role in whether the home is titled as personal property or real property, and that in turn affects financing and security of tenure⁴.

What does it cost to deliver and set a manufactured home?

No agency publishes a figure. Installation is federally regulated under 24 CFR Part 3285¹ and HUD lists regulating installation among its program functions², but neither publishes what the work costs, and no federal series covers transport, site preparation, foundation, utility connections or permits either. Census publishes the price of the home itself, $127,200 on average in 2025⁵, and that price excludes all of it. Collect itemized local quotes.

Can the installer deviate from the manufacturer's instructions?

The regulation sets a clear condition. Manufacturer instructions are deemed to comply with the Model Installation Standards only if they meet or exceed the minimum requirements of those standards and do not take the home out of compliance with the Manufactured Home Construction and Safety Standards at 24 CFR Part 3280¹. That is the yardstick. Ask for the instructions in advance, keep them, and raise any departure from them at the time rather than after the set is finished.

What if something is wrong after the home is set?

Start with the retailer and the manufacturer. HUD states that complaints about the performance of your manufactured home that have not been resolved by the retailer where you bought it or the manufacturer that produced it should go first to the State Administrative Agency where you live, or to HUD if your state has no such program⁶. Have the serial and label numbers ready⁶. HUD also lists administering dispute resolution among its program functions².
