Building Your ADU in La Mesa
Can two-story ADUs be built in La Mesa?
In La Mesa, ADUs must adhere to the height restrictions of the underlying zoning district, with possible height limits set at either 20 feet or 30 feet, depending on the specific zone. For instance, zones R1E, R1R, R1S, R1, R1A, and R2 have a maximum height limit of 20 feet, while zones R3 and RB allow for up to 30 feet. This means that a two-story ADU could be feasible, even with reduced setbacks of four feet from both the rear and side of the property. Importantly, the height of an ADU in La Mesa is measured from the average finished grade to the plate line of the roof, rather than the peak, ensuring a uniform measurement that fits within local aesthetic and structural guidelines.
What parking arrangements are required for ADUs in La Mesa?
A parking space is not required for an ADU if it is located within a half-mile walking distance of public transit, including bus stops, situated within a historic district, or if it is converted from or attached to the existing space of a primary residence or accessory structure.
Can you rent out your ADUs in La Mesa?
Yes, ADUs in La Mesa can be rented out, provided the rental period is longer than 30 days. This regulation supports the city’s goal to increase the housing supply and allows homeowners to earn rental income.
ADU Size & Building Constraints in La Mesa
What is the size limit for detached ADUs in La Mesa?
The maximum size for a detached ADU in La Mesa is 1,200 square feet. However, property-specific factors, such as lot size or coverage, may reduce this limit to 800 square feet.
How tall can ADUs be in La Mesa?
In La Mesa, ADUs are subject to height restrictions based on the zoning district, with limits of 20 feet in zones R1E through R2, and 30 feet in zones R3 and RB. This regulation permits the possibility of two-story ADUs with minimum setbacks of four feet from rear and side property lines. The height is measured from the average finished grade to the roof’s plate line, not the peak, ensuring consistency with local aesthetic and structural standards.
Is it permissible to construct roof decks on ADUs in La Mesa?
In La Mesa, the construction of roof decks on ADUs is influenced by the zoning district-specific height restrictions. For zones R1E through R2, the height limit is 20 feet, and for zones R3 and RB, it extends up to 30 feet. These limits are measured from the average finished grade to the roof’s plate line, allowing the potential for roof decks within these parameters, especially if building a two-story ADU with minimal setbacks of four feet from rear and side boundaries. This setup ensures that any roof deck aligns with local aesthetic and structural guidelines.
What exterior design standards apply to ADUs in La Mesa?
In La Mesa, ADUs must architecturally match the primary residence, using similar materials, colors, and design elements. They are also required to meet specific setback and spacing requirements for safety and aesthetics. In historic districts, ADUs need to closely mirror the architectural style and materials of the primary or historic structure.
Where can ADUs be located on a property in La Mesa?
ADUs are allowed across all residentially zoned areas in La Mesa, provided there is an existing or proposed primary residence. The city supports ADU placement on properties to increase affordable housing options, without strict lot size requirements.
Does La Mesa enforce a minimum lot size for constructing an ADU?
No, there is no minimum lot size requirement for ADU construction in La Mesa, which broadens the opportunity for property owners to develop ADUs, thereby increasing the city’s housing stock.
Renting Your ADU in La Mesa
Renting out an ADU in La Mesa offers a viable opportunity to capitalize on rental income while addressing the city’s housing needs. Homeowners should consider local market demands, potential rental income, and adherence to landlord legal requirements, including managing utilities and securing a separate mailing address if necessary. This process involves understanding La Mesa’s rental market, ensuring compliance with rental regulations, and considering the ADU’s impact on property taxes and insurance.
