Getting a Prefab ADU in Southern California - Buyer’s Guide

These features should guide your decision-making when buying a prefab ADU: 

Unit Size

You must know the size of the prefab ADU you want to get before anything. 

Firstly, you don't want to get a unit bigger than the available space in your backyard. You end up wasting time and money even if you can return it. This is because you will pay for transportation of the unit to and from the site. 

Knowing the size you want also helps you understand which company to approach. 

Another reason is that there are regulations about the size of units in some jurisdictions within the state. An example is the 800-square feet limit for one-bedroom ADUs in San Francisco. 

You don't want to break any building codes on size. 

Floor Plan and Unit Design

Knowing the size of the prefab ADU you want is not enough. Have a fair idea of the floor plan and unit design before you buy one.

ADUs are smaller, but this is no excuse for them to be cramped. You must check out the designs and layout plans of the units you want to buy. With the appropriate design scheme, your ADU can feel spacious. 

To make your ADU this welcoming, opt for layouts that maximize space. Your floor plan should be open with a few partition walls between the different living areas. 

Choose a layout that lets in as much natural light as possible. This means opting for designs with large windows, skylight installations, and sliding glass doors. Such a layout makes the unit seem bigger than it actually is. 

Prefab ADUs with tall ceilings also help your space feel larger. However, there are regulations in certain California jurisdictions that only allow ceiling heights up to 16 feet. 

The best ADU designs integrate several built-in storage spaces. This way, you don’t have large dressers taking up floor space. Wall storage, shelves, and multipurpose furniture units keep your floor plan as open as possible. 

Floor Plan and Unit Design

Permits and Certifications

Federal and state building codes guide what you can construct and how to do it. These ensure that properties don't infringe on the rights of other citizens, are safe to be inside or around, and are also environmentally sustainable.

California enforces specific energy efficiency standards to ensure that ADUs are eco-friendly.

Another example is the Certified Passive House Designer certificate which assesses homes based on their ecological footprint.

Your ADU company should also follow the California Green Building Standards Code (CALGreen).

These regulations include standards for environmental factors such as water and energy efficiency and material conservation.

Installation Skills Required

After buying the prefab ADU comes the issue of installation. Are you going to do that yourself, or will you get help from professionals? 

Some companies provide in-house teams to help you set up the unit you buy. This saves a lot of time and effort, even though it may come at an extra cost.

Installation Skills Required

Turnkey Level

Turnkey covers the time it takes for your ADU to be ready to use after buying it. Choose a unit with a short period if you are in a hurry. However, if you have time to spare, you can take your time. 

You pay more for those with short turnkey times.

Conclusion

You’ve put a lot of thought, time, and research into adding an ADU to your property. That makes choosing a company that will support your vision, facilitate the entire process, and produces quality results even more important.
