Not every land is permitted to have an ADU built and passed on their structure. For San Bernardino, just like most of California, an ADU can only be built on a property that has an existing primary home. The owner of the property must occupy the primary home, though in some cases, exceptions may apply, too. For instance, in the case of a detached ADU, the primary property does not need to be owner-occupied. But for attached or Junior ADUs, the property should be occupied by the owner only.
Number of ADUs Allowed
Matching to the San Jose ADUs regulations, a single-family home property only allows 1 ADU to be built on that structure. Additionally, if the owner is living on the property, it is allowed to have a Junior ADU, too.
Size and Height of Unit
State regulations specify that an ADU on a single-family property may have a maximum floor space of 800 sf and a minimum floor area of 150 sf. Larger sizes may be permitted by local regulations, although there may be extra conditions. This maximum floor area of 800 square feet is applicable in cases of a single-bedroom unit. For a two-bedroom unit, the property size should be up to 100 square feet to make the property suitable for living. For a Junior ADU, the minimum size requirement is 500 square feet.
Secondly, for the height of ADU, the structure should be no taller than 16 feet for a detached structure. Or it should not exceed the primary property on the lot, making the space look uneven or unpleasant. For an attached ADU, the height can be up to 25 feet, and these limits are not applied for conversion ADU structures.
For parking and similar laws, the ADU regulations are very similar to San Diego ADUs regulations and Los Angeles ADUs regulations in many ways. If the ADU is located within a half-mile walking distance of a public transportation stop, it is free from parking restrictions. The local authority shall not demand that those off-street parking spots be restored when a garage, carport, or covered parking structure is destroyed in conjunction with the development of an accessory dwelling unit or when it is transformed into an accessory dwelling unit.
The ADU for San Bernardino must have a minimum setback of 4 feet from the original property. This setback needs to be followed around the rear and interior sides of the property lines. For conversion of ADUs from existing structures or garages, there is no rule of following a certain setback rule, and ADU can be built freely on the land.
