First Choice For Prefab ADUs In San Diego

San Diegans Trust Organic ADU with Their ADUs in San Diego County

Prefab ADUs in San Diego are some of the most popular construction projects in the San Diego area. Whether you want to add a source of income to your property, create a guest house, or prepare for multigenerational housing, an ADU might be the answer you need.

These projects come in two main types: custom and prefabricated.

Prefabricated designs are more inexpensive than custom ones. They have parts and plans that can be more easily put together. A prefab option is often the best choice for your budget for those who want a detached ADU.

Timeline For Prefab ADU San Diego Construction

Since the pieces of a prefab model are built offsite and then shipped to the property, they can be assembled more quickly than custom designs. With a custom stick-and-build model, everything is put together onsite instead.

Prefab timelines are also subject to fewer hiccups and delays than custom model timelines. Again, since the pieces are manufactured offsite, you don’t need to be concerned about inclement weather or other delay-causing issues.

When considering the timeline, you need to consider the time it takes to receive building permits and construct the pieces offsite. However, actual construction on your property will likely take less time than a custom model would.

Our ADU specialists will work with contractors to do the following:

  • Build a foundation for the unit
  • Prepare the foundation for the modules
  • Put the modules together

We will also work with professionals like plumbers and electricians to make the unit move-in ready. Once everything is constructed, there will be a final inspection to ensure everything corresponds to what you want.

About Prefab ADUs in San Diego

Over three million people live in San Diego county, but there are only about a million homes. California has been dealing with a housing crisis for years. As the population grows, home construction hasn’t been keeping pace. And it’s difficult to create affordable housing.

That’s where granny flats come in.

Granny flats are a popular way to create multigenerational housing on a single property. You can also use them for property owners to receive rental income from a tenant. In San Diego, they are one of the key ways people deal with a housing shortage.

Over the past few years, more than 30 percent of the housing construction projects in San Diego have been ADUs. Before that, these housing options were rarely, if ever, used.

San Diego encourages the building of ADUs in several ways. For one, they have waived thousands of dollars in initial fees so that many more homeowners can access the option. They also make it easy for people to find floor plans that work with city zoning laws.

Our ADU specialists in San Diego have an intimate knowledge of the rules and regulations surrounding these homes. If you want to add to your property’s value or increase your living space, a prefab ADU might be the place to start.

Benefits of a Prefab ADU in San Diego

Prebuilt flats have quite a few advantages. These are some that you might take into consideration.

Less Waste

Since pre built models have their pieces manufactured offsite. You’re less likely to end up with wasted supplies at the end of the project.

In addition, factories protect their materials. It’s less likely that housing materials will be damaged or stolen in a factory than in an open construction site.



Some people assume that prefab homes are less durable than stick-and-build ones. But that isn’t true.

The pieces of a prefab home need to be shipped over highways, driven by trucks that go at least 60 miles per hour. To withstand the journey, they reinforce the materials for maximum durability.

It makes a prefab more likely to withstand natural disasters like earthquakes and hurricanes.


Short Construction Time

The construction timeline will vary depending on the size of the project. However, prefab projects often take less time than custom options. Pieces can be manufactured offsite while the property is being prepared for construction.

The National Association of Home Builders says that you can build most prefab home models within half a year. Most custom options take longer than that.


Less Expensive Cost

The cost for a prefab model will typically be less than that of a custom model. It will vary depending on the size and scope of the project.

With a prefab model, you have a sense of the cost right away. You’re also less likely to run into unexpected expenses during the process.

You can talk to our ADU specialist about the potential costs of prefab models to decide which option is right for you.

Frequently Asked Questions About Prefab ADUs

Can I put a prefabricated guest house on my property?
The rules about prefab guest houses vary depending on the state and city. If you live in San Diego, you have several options to place a prefabricated guest house near your own.

California has recently put new laws into place regarding ADUs. In San Diego, more and more people want ADUs because of the need for multigenerational housing or extra income from a tenant.

The San Diego county has waived the initial fees for starting this kind of project, making it accessible to many more homeowners. If you want to add a guest house to your property, you can talk to one of our specialists at Organic ADU to make it happen.

How much does a prefab ADU cost in San Diego?

Prefab ADUs are less expensive than custom ones. They’re designed to fit in a backyard or other part of your property. Most are not made to attach to your existing home, which allows them to be assembled more easily.

The cost of a unit is typically calculated based on square footage. The structure and size will also affect this number. Larger ones will be less expensive per square foot.

Another thing to keep in mind is that two-story units tend to have higher costs than single-floor units. For those on a budget, it’s best to look for a one-story ADU option.

You can talk to one of our ADU specialists about the project’s costs, including whether there are any costs calculated after the initial prefab price.

Generally, the price estimate for a new ADU in San Diego can range from $180 to $450 or more per square foot. The estimated price is all-inclusive, which means that the cost of the granny flat components, interior design, site work, and labor are included. However, the cost may vary on a case-to-case basis. 

Our ADU specialists will discuss your vision and go over some options to determine an accurate estimate for your new ADU.

How long does it take to build a prefab home?
You can have a prefab home built much more quickly than most custom home plans. Some projects might even take just a few months. The size of the project makes a difference – larger homes will take longer to put together than smaller ones.

When you choose a prefab home, most of the structure’s pieces come ready to use. It’s much easier to put them together than to create a custom building from scratch.

There will be a few weeks necessary to get your permits and home design in order. It usually takes about a week to prepare the site.

You can have most foundations built within about a month. Then we will do the modules for the home in about a week. Setting and installing the modules takes another month.
