Manufactured vs. Modular Homes: Key Differences and Considerations for Homebuyers

When it comes to affordable housing options, manufactured and modular homes are both popular prefabricated housing choices. Though they may seem similar at first glance, there are significant differences in their construction, regulation, and overall design that can impact a buyer’s decision.

Manufactured vs Modular Homes

Definition and Construction

Manufactured Homes: Manufactured homes, formerly known as mobile homes, are built entirely in a factory setting under federal code administered by the U.S. Department of Housing and Urban Development (HUD). This means that the construction, design, and safety standards are uniform nationwide. After manufacturing, the homes are transported to their location in one or more sections on their own chassis and wheels, which are often removed once the home is placed.

Modular Homes: Modular homes are also factory-built, but they are constructed in sections or modules. These modules are then transported to a building site where they are assembled on a permanent foundation. Unlike manufactured homes, modular homes must adhere to local building codes that vary by state and even by municipality, similar to traditional site-built homes.

Regulation and Standards

Manufactured Homes: The HUD Code, which was implemented in 1976 and has been updated regularly, governs the construction of manufactured homes. This code covers a wide range of criteria, including heating, plumbing, air-conditioning, thermal and electrical systems. The HUD Code also ensures that manufactured homes are built with durability in mind, able to withstand transport to their final location.

Modular Homes: Modular homes are subject to the building codes of the state, county, or city where the home will be located. This means they must be inspected by local building inspectors, unlike manufactured homes which are inspected in the factory. The standards can be more stringent, often leading to higher building quality and customization options compared to manufactured homes.

Foundation and Installation

Manufactured Homes: These homes are typically installed on a non-permanent foundation, making them easier to relocate than modular homes. Common types of foundations used include pier and beam, and slab setups. It is crucial for homeowners to ensure that their home complies with local zoning regulations, which can sometimes restrict the placement of manufactured homes.

Modular Homes: Modular homes are placed on a permanent foundation, similar to site-built homes. This can include full basements and crawl spaces. The permanent foundation contributes to the stability and durability of modular homes, making them similar in property value and financing options to traditional homes.

Design and Customization

Manufactured Homes: While there has been significant progress in the design options available for manufactured homes, they are generally limited to a few layouts and customization options due to the constraints of manufacturing and transporting them. However, they are less expensive, which makes them an attractive option for many buyers.

Modular Homes: Modular homes offer a greater range of design flexibility. They can be customized in countless ways, including multiple floors and extensive architectural detailing. Homeowners can work with builders to create a unique home that fits their specific needs and tastes, closely mirroring the experience of building a traditional site-built home.

Cost and Financing

Manufactured Homes: Typically less expensive than modular and site-built homes, manufactured homes offer a lower entry price, making homeownership accessible to more people. Financing a manufactured home can be different from a traditional home loan, with some buyers opting for personal property loans if the home isn’t attached to a permanent foundation.

Modular Homes: The cost of modular homes can vary widely, depending on the complexity of the design and the local costs of labor and materials. They are generally more expensive than manufactured homes but can be less costly than a comparable site-built home. Financing for modular homes is typically the same as for site-built homes, with standard mortgage options available.

Resale Value and Longevity

Manufactured Homes: The resale value of manufactured homes can depreciate over time, much like vehicles. This depreciation is particularly significant if the home remains on a non-permanent foundation and retains its ability to be moved.

Modular Homes: Modular homes tend to retain value and appreciate similarly to site-built homes, especially since they are often indistinguishable from traditional homes once assembled. Their durability, adherence to local codes, and permanent foundation help in maintaining their value over time.


Choosing between a manufactured home and a modular home largely depends on your budget, design preferences, and long-term housing needs. Manufactured homes provide a more cost-effective option with quicker setup times, while modular homes offer the benefits of traditional construction with potentially quicker completion and some cost savings. Understanding these differences can help potential homeowners make a decision that aligns with their lifestyle, budget, and long-term objectives.


Manufactured homes and modular homes are both affordable prefabricated housing options, but they differ in construction, regulations, and installation. Manufactured homes are built entirely in factories under federal HUD code and are usually placed on a non-permanent foundation, making them easier to relocate. They are generally less expensive but may depreciate over time. Modular homes are constructed in modules at factories and then assembled on a permanent foundation at the site, adhering to local building codes. They offer more design flexibility, similar financing and property value appreciation as traditional homes, but can be more costly than manufactured homes.
