FAQ
What is an ADU?
An accessory dwelling unit (ADU) is a second complete dwelling unit which is built within or on the same lot as an existing single-family residence. An ADU provides complete independent living facilities including a kitchen, bathroom, and its own entryway. ADUs are typically not allowed to be sold separate from the primary home and the homeowners are usually required to reside in one of the two units.
Why are people building ADUs?
Thousands of new ADUs are being built in communities across the U.S. because they are a manageable and minimally-disruptive option for adding desperately needed housing to existing neighborhoods. Moreover, ADUs typically cost less than other forms of housing and make efficient use of existing land.
How are your ADUs different?
We build prefab modular buildings, which means you get your ADU faster than conventional on-site construction.
Whereas all the work on a conventional construction site happens one after the other, we can start site preparation and building construction at the same time because all of our construction happens offsite in a factory.
Our buildings are also made from up-cycled shipping containers, which are already manufactured units by default.
Why shipping containers?
With a shipping container, not only do we reduce waste and repurpose scrap metal, but the container acts as an extremely durable, waterproof, fire resistant, and earthquake-rated body/chassis for the rest of our build.
How do you make the ADUs?
Because our process begins in a factory, we can deliver your unit with complete framing once the sitework is prepared. We load up our models in two sections and deliver to your site using a crane. Once installed permanently to the foundation, our team of contractors will install all the electrical wiring, plumbing, and fixtures before connecting your model to existing utilities.
What’s included in your ADUs?
All of our ADUs are completely finished and equipped with appliances and built-in cabinetry. To read additional information on our prefab ADUs, click here.
In addition to our turn-key ADUs, our construction project management services are included in our unit pricing at no additional hourly cost, which includes a member of our team who will handle all the permitting discussions with the Planning and Building Departments.
How long does it take to build my ADU?
Typically, it takes 4-6 months (Depending on the model) from the moment you order your prefab ADU* to the day we hand you the key. This provides us time to modify our containers in multiple sections to be assembled, connected, and secured on-site.
On occasion, it takes longer to receive materials to complete our project, in which case we will inform you of the delays. Additionally, we may be delayed by city inspection scheduling, in which case we will inform you of the delays.
*Custom container projects or modifications that required adjustments to prefab plans will require additional time and may include service fees for design and engineering.

How long does it take to get permitted?
Because our base models are standardized, total permitting can take up to 2-6 months.
Custom projects tend to take more time to permit than our prefab ADU because of additional architectural and structural requirements, of which we’ve already completed for our prefab models. However, due to the modular nature of our buildings, we have a series of structural connections that have been tested, calculated, and drawn that can be repurposed with custom designed hardware to create most custom spaces.
Can I finance it?
Yes, financing is certainly an option. We have worked with several local banks over the years that have products that may suit your needs. Please contact us directly and we can discuss what financing options you may have given your situation.
Can I customize it?
Absolutely! Although the structure for our prefab ADUs are fixed, you can customize most of the exterior and interior within our fixed pricing. Some special exterior and interior materials have premiums, but we will be sure to discuss this with you in advance of purchasing material.
To read more about our possible customizations, you can view our Prefab Models page to learn more about our customizations, including: flooring, exterior paint, interior paint, cabinetry, countertops, and tile.
Can I stack multiple containers?
Our containers are ISO-rated intermodal shipping containers that fall under ICC G5 guidelines for safe use. On ships, these containers can stack as much as 8 units high. However, due to zoning and planning limitations within neighborhoods and most commercial zones, we are typically only able to stack 2-3 units high to meet local requirements.
What does it mean that you handle everything?
Our prefab ADUs are turn-key.
You work with one project manager who manages the construction of your unit in addition to all on-site work, so you don’t have to work with multiple contractors.
Our team of designers, architects, and engineers will work together to select the best model for your lot. From permitting to final installation, we partner with you to realize your ideal space.

Can I put an ADU on my property?
Most major cities on the West Coast permit the construction of ADUs as a secondary housing unit. Cities and counties are constantly working to update codes and reduce fees to encourage the development of ADUs because they provide additional housing.
Planning & Zoning fees and regulations will vary by municipality but most cities allow ADUs.
Other requirements include ensuring proper setbacks and adhering to size requirements. We can help with this during our submission to the permitting office.
Can I rent it out?
In most cases, your ADU can be rented out! Yay, rental income 🤑.
However, different cities have requirements for duration of rental and whether the property owner resides in the primary home or ADU.
An SB13 update voided owner-occupancy requirements for ADUs for 5 years.
How will an ADU affect my property value?
A permitted ADU will enhance the curb appeal of a house on the market by adding additional square footage to the property. ADUs are seen as investments that are reflected in the appraised value of properties.
What happens to my property taxes?
A permitted ADU will result in an increase in property taxes equal to the assessment of the ADU as an improvement to the property. It should not result in a new assessment of the rest of the property. The homeowner’s property tax bill can still increase as a result of standard annual increase in taxes and new levies that are added to property taxes each year unrelated to the ADU.
How does an ADU access utilities?
We access sewer and water service by connecting to the main sewer and water service to the primary residence. We connect to the existing electrical service of the main panel and route a line via conduit to a subpanel in the ADU. We do not use natural gas in our ADUs.
What else can I do with my ADU?
It’s up to you how you use your ADU! If you or a renter is not living it — many use the extra space to be creative with music, art, fitness, etc.
What’s the difference between modular and prefab?
Modular is a style of building refers to the creation of modules or sections of a building (usually built offsite) that are later assembled (on-site).
Prefab is a term that defines the offsite building of these modules.
What’s the benefit of building prefab?
Buying a prefab ADU has a host of benefits, which include:
greater time and cost predictability
fewer distractions and disturbances at your residence
faster speed to market
lower cost due to fewer workers on site
far less construction waste due to ordering and delivering specifically manufactured parts
the ability to streamline reviews with planning departments with a pre-approved set of drawings
reduced accidents, normally due to lack of necessary equipment on a job site
