Expert Architects in Alhambra, CA

An ADU (also referred to as a backyard home, granny flat, in-law suite, guest house, back house, etc.) is a separate living unit complete with its own entrance, living space, kitchen, and sleeping areas.

The permitting process can take 2-3 months. Construction on an easy garage conversion can take as little as 2 to 3 months, and a more complicated larger project can take up to 5 months.

We begin with a free in-person consultation and home evaluation. This will help us see your vision, weigh your options, and plan your project. Next, we will discuss possible financing options. Once you have decided to move forward with your project, we will design and put together architecture and engineering plans. The plans will be submitted to the city, and permits will be obtained. We will begin construction as soon as permits are obtained. After construction is complete, we will have a final inspection, and your ADU will be ready to enjoy! Either move in yourself or rent it out to tenants! We can even help with that!

The existing service to typical single-family residences is usually sufficient to support a Backyard ADU. On the contrary, ADU Resource Center will work with you to upgrade the necessary services to support the ADU.

Yes, but not much. When you build an ADU, the city will do a blended assessment, which does not affect the value of your existing property, but instead, assess the cost of the construction and adds that to your original property value. Your taxes will only increase by 1.1% of the total cost of the improvements.
