1. What is an ADU?

An ADU is a secondary housing unit that is located on the same property as a single-family home. ADUs can be used for a variety of purposes, such as a guest house, in-law suite, or rental property.

2. What are the different types of ADUs?

There are two main types of ADUs: detached and attached.

Detached ADUs are separate structures that are located on the same property as the single-family home.

Attached ADUs are connected to the single-family home, but they have their own entrance and kitchen.

3. What are the benefits of adding an ADU to my home?

There are many benefits to adding an ADU to your home, including:

-Increased space: An ADU can provide you with extra space for a guest room, in-law suite, or rental property.

-Increased value: An ADU can increase the value of your home.

-Tax benefits: In some cases, you may be able to claim tax deductions for the construction of an ADU.

-Rental income: If you rent out your ADU, you can generate additional income.




Fahid, Moein and the entire Lavan team are just terrific. Extremely professional, polite, reliable, and from start-to-end just delivered as promised. Project was completed on time and at cost, and they consistently above and beyond to make sure we were happy. Work product is of highest quality, and the team is super responsive and friendly. We would work with them ahead in a heart beat and recommend Lavan to anyone!



We engaged Lavan construction for renovation of 2 bathrooms and addition of a number of storage closets in our house. We thoroughly enjoyed working with them beginning from the design phase to construction. The 3d renderings that Lavan provided of the choices we made for the bathroom stall shower was very helpful to visualize the final look. The tile work in particular was excellent. The quality of the material used and the execution was perfect to the last detail. Overall we are very pleased with our experience with Lavan. Worth the money we spent.



This was our first remodeling project and Moein spent several mornings patiently explaining the remodeling process and industry. We ended up having to postpone our project for family reasons, but we plan to use Lavan's services as soon as we can.
