Mobile Home Additions: Practical Ideas to Upgrade Your Manufactured Home

Modern homes offer the same comfort as site-built homes. They’re a great deal of flexibility since you can make customizations to your liking. Mobile additions are all about aesthetics and functionality.

Mobile Home Additions

With a bit of color or greenery, a porch or garden could enhance the look of your mobile property. It’s great to have extra rooms for entertaining guests or to move around. You can also get more space with an addition.

To make a great mobile home addition, you must put in a lot of time and work. It involves designing, planning, getting permits, and hiring qualified contractors.

If you want to revamp your mobile home or move into one pretty soon, keep reading for some helpful tips.

Things to Consider Before Starting a Mobile Home Addition

Adding on to an existing house may seem less expensive than buying a new one, but the truth is that it could cost just as much or even more. The best part is that you won’t have to move from home when making the addition. A reasonable budget will help you stay on track and avoid overspending.

Also, remember that an addition should be a separate structure from the main home. Its foundation maintains stability and is easy to dismantle when relocating. Now, let’s get into the details of a mobile home addition plan.


Each house addition project has its own set of costs. The type, size, and style will all impact the cost. On top of that, enclosed sections, such as bedrooms, bathrooms, and kitchens, require more time and money to redesign.

Such upgrades require some plumbing, and you’ll need to engage electricians during construction. Decks, porches, and carports are much cheaper and easier to install. You can get a quote and a list of requirements from your local contractor.

An addition may not be the best option if you plan to sell the house. A potential buyer may not find it enticing, thus the reason for this. We all have different tastes. Above all, building a dingy extension loses the curb appeal of your mobile home.

Building Permits

Mobile Home Additions

Mobile home modifications require permits from local officials. You or your licensed contractor can seek these permits. This step is necessary for any mechanical or electrical work and the addition of new rooms, windows, and doors.

Before starting the construction process, check with your mobile home park for approval. It’s not unusual to find mobile home park managers limiting the number of detached structures in your neighborhood.

You might need site assessments to confirm that your property’s water, septic, and electrical infrastructure can support the addition. After completion, the state municipality will inspect the construction to ensure it follows plans and building codes.

Fire exits, air conditioning, and wiring should be on your checklist. It’s critical not to skip any of these processes. If you need financing or decide to sell, the requisite parties will need to see these permits.

Quality of Build

Mobile home additions should have a separate foundation. Each addition needs at least four-footers on each corner so there can be an even weight distribution. It’s best to hire a professional to help inspect for any mishaps.

You want to build a framing that’s as sturdy as that of the mobile home. This HUD guide illustrates more about foundations and support structures while making additions to mobile homes. There are also local building codes that manufactured homeowners must follow.

Sealing the entire addition binds it with your mobile home and prevents leaks. It closes all gaps that would lead to leaks and water damage. The same goes for roof additions. Your local electrical codes should help you pass all the inspections. Hiring a professional electrician is worth it when dealing with cords and sockets.


Anyone entering or living in a mobile home should feel safe. On purchase, a mobile home must have enough floor space to accommodate at least two exit doors. The Federal Emergency Management Agency also recommends this.

Because a manufactured home can only support its weight, any additional space requires its foundation structure. Again, the reason for building the extension adjacent to the main house is to make sealing much easier.

It reinforces and makes the extension sturdy when moving. You should also expect no damage to the mobile home when dismantling it. The addition should maintain moisture-control ventilation and not interfere with the crawl space.

You must be careful not to void the manufacturer’s warranty when making upgrades. Be sure to inform them of any modifications you wish to make when placing your order. It’s best to avoid making more modifications, as the manufacturer will no longer be liable for any issues.
