In San Diego County, the size you can buy is shaped as much by the lot as the budget, because park lots and coastal parcels don’t all fit the wider models. This guide breaks down the real dimensions, what each size tends to cost here, and how to pick the one that fits your land and your life.
Size is where most manufactured home decisions start, and the “wide” in the name is the key. It doesn’t describe width alone. It describes how many transportable sections the home is built in and hauled to the site. That single fact drives square footage, price, financing, and whether a home will even fit the lot you have in mind.
What’s the difference between a single-wide, double-wide, and triple-wide?
The difference is the number of factory-built sections. A single-wide ships as one long section and needs no on-site joining. A double-wide ships as two sections that get connected on the lot. A triple-wide, sometimes called a multi-section home, ships as three. More sections mean more width, more square footage, and more rooms, but also a wider lot and a bigger move.
Here’s how the three compare on the numbers that matter to a buyer.
| Feature | Single-wide | Double-wide | Triple-wide |
|---|---|---|---|
| Sections | One | Two | Three |
| Typical width | 14 to 18 ft | 20 to 36 ft | 36 ft or more |
| Living space | Model-specific; verify the floor plan and transportable section | Model-specific; verify both sections and joined dimensions | Model-specific; verify every section and installed dimensions |
| Bedrooms | 1 to 2 | 2 to 3 | 3 to 5 |
| Feels most like | A compact apartment | A small single-family home | A full-size house |
The categories overlap on purpose, because floor plans vary by manufacturer. A generous single-wide can rival a small double-wide, and a compact double-wide can feel like a large single-wide. Read the actual floor plan, not just the label.
Single-wide vs double-wide manufactured homes: sizes and square footage
For most San Diego buyers, the real choice is between a single-wide and a double-wide. The gap between them is bigger than the numbers suggest, because a double-wide’s second section usually goes toward living space, not just extra bedrooms.
A single-wide’s narrow footprint means rooms line up down one hallway. That layout is efficient and easy to heat and cool, which matters on a fixed budget. A double-wide opens up. You get a real living room, a kitchen you can move around in, and often a primary suite. If you plan to stay for years or you have a family, that extra section changes daily life more than the square footage alone shows.
To see how size flows into price, compare floor plans against our manufactured home cost guide for San Diego, which breaks down what drives the final number. And if you’re still deciding between a manufactured, modular, or prefab home, our types explainer covers how construction method changes what you can put where.
How much do single-wide and double-wide homes cost in San Diego?
Price tracks the number of sections, the home’s age, and whether it sits in a park or on owned land. Single-wides are the county’s most affordable path into a home, which is why older single-wides in parks make up much of the entry-level market here. Double-wides cost more up front but hold their value better and appeal to a wider pool of buyers at resale.
| Home type | What buyers here spend on it | Why |
|---|---|---|
| Used single-wide in a park | The lowest entry point in the county | Older stock, smaller footprint, leased lot |
| New single-wide on land | Low end of new-home pricing | One section, less material and setup |
| Double-wide (used or new) | A clear step up from a single-wide | More space, stronger resale, family-friendly |
| Triple-wide on owned land | Toward the top of the market | Site-built feel, largest floor plans |
New manufactured homes built to HUD code cost meaningfully more as you move from a single-wide to a multi-section layout, and the structure is only part of the total once land and site work are counted. Get written dealer quotes for the exact models you’re weighing. Prices also shift by area, so check our manufactured home cost guide breakdown for local ranges. A home on a leased park lot appreciates differently than one on owned land, so factor the land question into the price. Our guide to what your mobile home is worth in San Diego explains that difference, and our manufactured home financing guide covers which loans reach which home sizes.
Which size fits San Diego parks and lots?
This is where local reality overrides the floor plan, and where national guides go quiet. The home you want has to fit the space you’re putting it on, and in San Diego County that space is often the constraint.
In a park, the lot sets the ceiling. Many San Diego parks have lots sized for a specific home width, and older or coastal parks tend to have narrower lots built for single-wides. A double-wide simply won’t fit some of them. Before you fall for a wider home, confirm the lot’s dimensions and setback rules with park management in writing. Our guide to San Diego County mobile home parks covers how park rules shape what you can place.
On owned land, you get more freedom on size, but the ground rules still apply. County setbacks, HCD placement standards, and the permanent foundation all scale with the home. Our putting a home on private land page walks through placement, and larger multi-section homes lean harder on that process. One more cost that grows with size: the move. A triple-wide takes more trips and more setup than a single-wide, as our cost to move a mobile home guide lays out.
Single-wide or double-wide: which should you buy?
There’s no universal winner. The right size is the one that fits your budget, your lot, and how long you plan to stay.
A single-wide makes sense when the budget is tight, you’re buying for one or two people, or the lot you want is narrow. It’s the fastest, cheapest way into a home in San Diego, and it’s easier to move later if your plans change. A double-wide makes sense when you need real living space, you’re housing a family, or you’re staying long term and want stronger resale. A triple-wide fits buyers on owned land who want the feel of a site-built house and have room to place it.
Whatever size you land on, line up the money and the lot before you shop. Our buying and placement process page shows the full path, and our manufactured homes for sale page and San Diego County hub show what’s available now, including the older-home parks in Chula Vista where many single-wides trade.
Frequently asked questions
What is the difference between a single-wide and a double-wide manufactured home?
A single-wide is built as one factory section and hauled to the lot in one piece. A double-wide is built as two sections that get joined on-site into a wider home. The double-wide gives you more width, more square footage, and usually a more open floor plan, while the single-wide costs less and fits narrower lots.
How many square feet is a single-wide vs a double-wide?
Exact sizes vary by manufacturer and floor plan, so check the plan for the specific home.
Is a double-wide worth more than a single-wide?
Location and land matter too. A double-wide on owned land holds value differently than the same home on a leased park lot.
Can you fit a double-wide in any mobile home park?
No. Many San Diego parks have lots sized for a specific home width, and older or coastal parks often have narrower lots built for single-wides.
Are triple-wide manufactured homes available in San Diego?
Yes, though they’re less common than single-wides and double-wides. Triple-wide, or multi-section, homes work best on owned land with room to place a wider footprint. They offer the most space and the closest feel to a site-built house, at the top of the local price range.
Which is cheaper to move, a single-wide or a double-wide?
A single-wide. It ships as one section, so it takes fewer trips, less setup, and a simpler permit. A double-wide moves in two sections and costs more to transport and re-join, and a triple-wide costs more still. Size drives the move, so factor it in before you buy a home you may relocate.
