An exception to the requirement described above, is when the front yard is the only area on the property which can accommodate an ADU that meets the definition of a “Statewide Exemption ADU”. That is, when the side and rear yard of the property are not large enough to accommodate an ADU that meets the definition of a Statewide Exemption ADU.
A Statewide Exemption ADU is defined an accessory dwelling that is less than or equal to 800 square feet in floor area, sixteen (16) feet tall, with at least four (4) feet side and rear setbacks.
This diagram shows a lot layout when it may be possible to request the location of a Statewide exemption ADU in the front yard setback. This diagram shows that the four (4)-foot sides and rear yards are not large enough to accommodate am ADU of at least 800 square feet (Statewide Exemption ADU). This type of lot layout is not typical for Tustin properties. It is anticipated that this would only occur in rare situations since most properties have a rear yard or even side yards to accommodate the location of a “Statewide exemption ADU” and other types of permitted ADUs or JADUs.
