Got a question? We've got an answer for that.

We understand you may have questions about LIM Living, our mission, and our products. Here are some of the most commonly asked questions we receive, along with our answers. If you don't see an answer to your question, please don't hesitate to reach out to us!

Do I need a permit to put an ADU in my backyard?

Generally, accessory units that are under 120 square feet typically do not require permitting. However, since the Mini unit needs electricity to provide lighting and power to the HVAC system, it's essential to confirm the specific requirements with your city or county's building department. They can provide you with the exact information on whether a permit is needed for your specific installation.

It's always a good idea to double-check with the local authorities to ensure everything is in compliance and to avoid any potential issues.

Is there a warranty?

Absolutely! We stand behind the quality and craftsmanship of our accessory units, and to ensure your peace of mind, we offer a comprehensive warranty for all of our units.

With every purchase, you'll receive a 5-year warranty that covers materials, workmanship, and structural aspects of the units. Your satisfaction and confidence in our products are of utmost importance to us, and our warranty reflects our commitment to delivering a reliable and durable solution for your backyard needs.

For more detailed information about the warranty coverage, visit our Warranty page for all the details. Rest assured, with our warranty in place, you can enjoy your ADU knowing that we have you fully covered.

Can I build this myself?

Absolutely! We've specifically designed and engineered our units to be user-friendly, allowing even the handy DIYer with basic construction knowledge to assemble them. It's like a real-life Lego home project that you can undertake with the help of a couple of friends.

To make the process even smoother, we provide a detailed and easy-to-follow step-by-step instruction manual. For any more complex parts of the installation, we offer video links to guide you through the process—think of it as an improved version of an Ikea project, complete with clear instructions and helpful videos. Learn more about the assembly process here.

We understand that you might have questions or need additional support during the DIY process, and we're here to assist you. You can contact us directly by emailing:

How quickly can the Carbon Mini be assembled?

You'll be pleasantly surprised by the efficiency of our Carbon Mini's assembly process! With a dedicated 3-person team, the unit can be fully assembled in just 3-5 days. However, it's important to note that this assembly time does not include the duration required for obtaining permits and site preparation.

Once your site is prepared and ready, you or your selected contractors will find the assembly process efficient and straightforward. You can read more about the assembly process here.

If you require any guidance or have questions during the installation process, our team is always available to provide support and assistance. You can contact us directly by emailing:

What types of foundations are the most suitable for a LIM Living ADU?

For our units, a pier foundation in the form of precast concrete footings is the most ideal choice. It allows you to place the unit on top of leveled soil or gravel while ensuring the proper clearance underneath. With precast concrete footings, there's no need to deal with the hassle of mixing and pouring concrete, making the installation process faster and more straightforward.

While our models can also be installed on a concrete slab, it would require several modifications to accommodate the anchoring of the foundation beams, provide an 18" crawl space beneath the foundations, and allow space for water pipes, sewage pipes, and electrical hookups.

Can the Carbon Mini be increased in size?

As of now, the Carbon Mini cannot be increased in size beyond its current specifications. However, we offer the Quartz unit, and an ADA accessible option in the Argon.

If you're interested in exploring these or our Slate apartments or Onyx village options further or have any other questions, please don't hesitate to get in touch with us.

Does the Carbon Mini come with a bathroom?

As of now, the Carbon Mini does not come with a bathroom included. However, if you are in need of an accessory unit that includes a bathroom, we offer the Quartz and Argon units.

Are there any additional costs to putting a Carbon Mini in my backyard?

Yes, there are additional costs outside of the purchase price of the Carbon Mini. Our upfront pricing does not include any sitework (such as utility connections, trenching, demolition, ground leveling, and foundation prep) and the cost of any sales tax or permit fees.
