No, that is not a misprint. Or an exaggerated number.
In fact, I am going to show you exactly how building one new 650 square foot ADU is projected to add over $1,000,000 to my net worth over the next 30 years (hint: you can copy this exact formula and do the same thing).Read More
How much will it cost to build a new ADU?
That is inevitably the first question you'll ask when considering a new ADU.
I do not blame you; that would be the first question I would ask as well. I mean there is no reason to spend time and money designing and planning an ADU that is going to be too expensive to build, or too expensive to afford.Read More

We've compiled a list of the most commonly asked questions related to Accessory Dwelling Units and their design and construction.
If you have a question that you don't see asked below, please don't hesitate to contact us.
An Accessory Dwelling Unit is a secondary living structure that occupies the same property as an existing single family residential property.
ADUs have their own independent areas for living, sleeping, eating, cooking, and sanitation.
In most cases, the answer is Yes. But, there are some restrictions that vary between municipalities that will determine how big your ADU can be, etc.
Contact us today to discuss your property and project. We will investigate what type of ADU can be designed and built on your specific property and discuss your alternatives.
Homeowners are motivated by all sorts of reasons when deciding to build an ADU. Below are a few of the most common reasons we see...
Guest House - An ADU can act as a charming retreat for your overnight guests.
Rental Income - You can make a lot of money providing safe and comfortable rental housing.
Granny Flat - ADUs are perfect for aging-in-place housing and allow your loved ones to remain close to their family.
Home Office - A dedicated home office can help you stay productive while working from home.
You do not need to occupy your new ADU and it can be built and used for investment purposes. You just can't sell the ADU individually from the main house.
A Detached ADU is a great option for you if you have the room for one.
Detached ADUs provide the most privacy due to their separation from the main residence. Your new ADU will not share any walls with the main house and will be a welcome addition to your backyard.
The Return On Investment (ROI) for a detached ADU is off the charts.
Attached ADUs are great when your current home is on a small lot, and the setbacks required by the zoning code make it hard to fit a detached unit on your property. You can create an awesome attached ADU by carving out a portion of your existing home, or really increase the value of your property by adding an attached ADU addition.
Attached ADUs allow homeowners the ability to add an ADU without sacrificing a large portion of their property.
Garage conversion ADUs are the least expensive to build and are the fastest to get approved. Garage conversion ADUs are also the quickest of any of the ADUs to build. If you want to add some quick cash flow to your property, or just need additional living space quickly, a Garage Conversion ADU might be your perfect solution.
No, your new ADU and the main house on the property cannot be sold separately.
No, covered parking is not required for the new ADU. In fact, a tandem parking spot in an existing driveway is sufficient in most instances.
Yes, if your property meets any of the following criteria you can waive the parking requirement for your new ADU.
How big your ADU can be will depend on the type of ADU you want to build, and the size of your current home.
Attached ADUs An ADU that is built attached to your main residence is limited to fifty percent of the existing living area. For example, if you current home is 1,500 square feet, your new attached ADU would be limited to 750 square feet.
Detached ADUs An ADU that is built detached from your home may be up to 1,200 square feet, but is sometime limited by the local ADU ordinances. In no case can a local ADU ordinance limit a detached ADU to less than 800 square feet.
