You need to apply for permits from the San Diego Department of Building and Safety, which gives permits and approves any building if you want to build an attached ADU on your land. The ADU design plan must adhere to all ADU building regulations and be properly certified.

If the ADU plan is deemed to be flawless, the city will issue permits following approval. You must here pay a modest or insignificant service fee. You are not required to pay the charge in some counties.

The maximum size of an attached secondary unit on a property is controlled differently in each jurisdiction.
You are generally not allowed to construct an ADU that is bigger than half the size of your actual property in California’s cities and counties. This means that the attached ADU cannot be larger than 1,000 square feet for a 2,000-square-feet residence.
In some local jurisdictions in California, an attached secondary unit may be erected up to the height of the original residence without having to adhere to any kind of setback laws.
If your property is small, it is generally ideal to develop such an attached unit because it helps to optimize the square footage or living area.
An attached ADU in a “single-family dwelling” must fully adhere to the San Diego ADU zoning guide and meet predetermined specifications. A wall or roof must be shared by the primary dwelling and any attached structures or units.
Similarly, a door cannot be constructed on the street-facing side of an attached secondary dwelling unit. Let’s examine some more important criteria for an attached secondary unit.
