ADU Floor Plans come in all kinds of different shapes and sizes. Some floor plans are detached from your primary residence, while other ADU floor plans are attached. Some ADU floor plans are even meant to be built within the footprint of your existing home. In reality, ADU floor plans can be created almost any way you want, as long as it follows local and state laws and codes. This is where things can get tricky. You must make sure that the ADU floor plan that you choose is legal and will be approved in your local jurisdiction. For example, if your architect or draftsman drafts an ADU floor plan for you that is 1,200 square feet, but then your city comes back and says the maximum allowed is only 800 square feet, you’ve just wasted a lot of time and money. Let’s get into the nitty-gritty of ADU floor plans and what’s allowed.
Check with Your City First
Before you even start looking at ADU floor plans, you should check with your city’s planning department to find out all of the requirements that they have regarding ADUs. This is incredibly important, because what is legal in one city might be illegal in the city a few blocks away. Some important questions to ask are as follows:
- What is the maximum size detached ADU that I can put on my property? What about attached ADUs? What about Junior ADUs?
- What is the maximum height limit for the ADU?
- Does your city have any specific requirements that must be met?
- Are you able to send me the written ADU laws and codes for this specific city?
After talking with someone at the planning department, you should have a better idea of what can and cannot be built. Once you have this information, you can then assess all of your options and determine what ADU floor plan will be best for you to build.
