Building Your ADU in National City
In National City, you have the opportunity to build two-story ADUs under specific conditions. Attached or detached ADUs must generally not exceed the height of the primary dwelling or 16 feet, whichever is greater. However, for ADUs built above garages or on lots smaller than 5,000 square feet, the allowable height increases to 25 feet. For properties near major transit stops, recent state legislation permits detached ADUs to adopt 4-foot side and rear setbacks and reach up to 18 feet. If the ADU’s roof pitch matches that of the primary dwelling, you can add an additional 2 feet, enabling the construction of two-story units.
The available regulations do not directly address the allowance for roof decks on ADUs in National City. Prospective builders should consult with the city’s planning and zoning departments to understand the specific requirements and determine if such constructions are permissible under local ordinances.
No, National City does not impose a minimum lot size requirement for constructing ADUs. Property owners can build ADUs regardless of their lot size, subject to other relevant zoning and building regulations.
ADU Size & Building Constraints in National City
In National City, detached ADUs can span up to 1,200 square feet and must maintain a minimum setback of 4 feet from side and rear property lines. Additionally, ADUs built within the existing footprint of a dwelling or other detached structures, such as a barn, are not restricted by maximum floor area limits, allowing for larger conversions.
According to National City ADU regulations, attached or detached ADUs must not surpass the height of the primary residence or 16 feet, whichever is taller. If the ADU is above a garage or on a lot under 5,000 square feet, the maximum height is 25 feet. For multi-family properties, detached ADUs are capped at 16 feet. Recent state laws allow detached ADUs within half a mile of major transit stops to have 4-foot side and rear setbacks and reach up to 18 feet in height. An additional 2 feet is permitted if the ADU’s roof pitch aligns with the main home, potentially accommodating a two-story structure.
