State law allows a local ADU ordinance to establish certain ADU development standards. However, these standards shall not include minimum lot size (see GC Section  65852.2(a)(1)(B)(i)). Therefore, a minimum Lot size requirement for a given zone classification shall not be the basis of a denial of a new ADU.

When submitting your Building Permit application, please indicate the ADU Standard Plan number you are using in the work description.
