If you’re running out of space at home, a quality home addition project is probably in order. While a single room addition or conversion of your existing space can bring many perks, full-blown ADU construction is sometimes the only viable option. For example, if there’s a chance of senior family members moving in with you in the near future, this home improvement project may be the best course of action for you.
Before you get the project underway, you’ll have to become acquainted with state laws regulating ADU construction. Read on to learn how to meet the necessary requirements for your ADU build. Then you’ll be ready to contact leading ADU builders in San Diego and get the ball rolling.
What qualifies as an ADU?
While ADU developments can take many different forms, there are certain features that they usually have in common:
- An ADU is built in addition to a main dwelling unit.
- ADUs are always smaller than the primary housing unit.
- They are usually subsequently added to the main residence.
- An ADU unit and the main residential building have the same owner.
- ADUs have to meet a variety of state regulations.
How big can an ADU be in California?
According to the San Diego County Planning & Development Services, an ADU construction that’s attached to the main house can be up to 50% of the size of your family home and no larger than 1,200 square feet. If the ADU is a separate structure, it can be 1,200 square feet in size no matter the square footage of the primary home structure.
What are other ADU regulations?
Every homeowner who wishes to build an ADU has to get a building permit. It is to make sure that the development follows all zoning, building, and safety regulations. If you’re planning to build an ADU addition on your property in Torrey Pines or elsewhere in San Diego, here are some of the state-wide rules that you will be expected to adhere to:
- The ADU has to be on the same lot as your primary dwelling unit, either attached to or detached from it.
- The owner can rent the ADU but is unable to sell it separate from the main house.
- You are required to submit mathematical calculations of the floor plan for both the main and the accessory unit.
- The garage is the only other secondary unit that can be connected to the ADU unless permitted by an approved Administrative Permit.
- A detached ADU is restricted to 24’ in height with the exception of multifamily complexes.
- The ADU should usually include a parking space (barring certain conditions).
- New ADU construction, either detached or attached, has to follow required front and exterior side yard setbacks and a side and rear setback of at least 4’.
