What is an ADU?
An Accessory Dwelling Unit (ADU) refers to a self-contained living space that can either be attached or detached to an existing single-family home. They are also referred to as a "granny flat" or in-law unit. Accessory Dwelling units are designed to function independently. They feature separate entrances, kitchens, bathrooms, and living areas, while still being part of the same property as the primary residence.
ADUs provide homeowners with flexibility in accommodating extended family members, tenants, or additional household needs without compromising the privacy or functionality of the main dwelling.
This versatility makes ADUs a valuable solution for increasing housing options while maintaining residential integrity.
Encinitas ADU Laws
Encinitas has implemented specific ADU laws to govern the construction and use of ADUs. The city’s ADU regulations fall under California State laws and have been tailored to meet the local needs.
Types of Accessory Dwelling Units Allowed
Encinitas accommodates both attached ADUs and detached ADUs to meet varied homeowner needs and lot configurations. State regulations allow for the maximum construction of two Accessory dwelling units, one of which can include a junior accessory dwelling unit (JADU).
Attached units share structural elements with the existing primary residence, while detached units stand independently on the property, offering flexibility in design and use.
Under California law, the maximum size for attached ADUs is set to up to 50% of the floor area of the existing main residence. They must include their own living, sleeping, and cooking arrangements.
Junior Accessory Dwelling Units (JADU's)
JADU’s differ from traditional Accessory Dwelling Units (ADUs) despite recent legislative changes that affect both. JADUs are smaller units created within the footprint of an existing single-family home, often converting spaces like garages or basements into independent living quarters within an existing primary residence.
Unlike ADUs, which can be up to 1,200 square feet in size and stand alone on a property, JADUs are limited to 500 square feet or 50% of the existing home’s living area, whichever is less. This distinction ensures that JADUs maintain a smaller scale and are integrated within the primary residence.
JADU's also promote affordable housing solutions without significantly altering neighborhood density or character.
Size and Setback Requirements
ADU size is capped at 1,200 square feet or 50% of the primary dwelling’s floor area, whichever is less, ensuring proportional development.
Setback requirements specify minimum distances from property lines, safeguarding privacy and minimizing visual impact on neighboring properties. ADUs in Encinitas are required to maintain a minimum setback of 4 feet from rear and side-yard property lines.
If an ADU utilizes these 4-foot setbacks, it must not exceed a height of 16 feet. ADUs taller than 16 feet must comply with the setback requirements specified by the underlying zoning regulations.
Additionally, it's important to note that street-side setbacks exceeding 4 feet do not apply in Encinitas. This means that even on a corner lot, ADUs can be constructed with a minimum 4-foot side setback, ensuring flexibility in property development while adhering to local zoning standards.
Height Requirments
Height restrictions typically permit one or two stories based on the zoning district and lot size. This ensures that ADUs blend harmoniously with surrounding properties while maintaining aesthetic and structural integrity.
Homeowner Occupancy Requirements
In Encinitas, the regulations regarding owner occupancy for ADUs align with broader state laws. California state law no longer mandates owner occupancy for ADUs on the same lot as a proposed or existing primary dwelling.
Assembly Bill 976, implemented from January 1, 2024, prohibits such requirements statewide, allowing ADUs to be rented out without the primary residence being owner-occupied. This change reflects efforts to increase housing flexibility and accessibility across California.
Rental Regulations
Encinitas implements rental regulations for Accessory Dwelling Units (ADUs) to maintain residential integrity while accommodating housing needs:
Encinitas may impose limits on the duration of ADU rentals to ensure they contribute to long-term housing solutions rather than short-term rentals. These restrictions help maintain community stability and prevent ADUs from being used solely for vacation rentals.
Homeowners interested in turning their ADU’s into short term rentals must fill out a Short-term Rental Permit application form. This form contains information about short-term rental fees and additional information about short stay ADUs.
These measures aim to balance housing supply with community cohesion, ensuring ADUs contribute positively to neighborhood dynamics.
Parking
In Encinitas, ADUs are exempt from parking space requirements under the following circumstances:
- When located within a one-half mile walking distance from public transit, such as bus stops.
- Within designated historic districts recognized by the city.
- When converted from existing space within the primary residence or an accessory structure, or when attached to an existing or proposed primary residence. Additionally, exemptions apply if the ADU is part of a property that already has a primary residence.
These exemptions reflect efforts to reduce parking demands and promote sustainable transportation options while accommodating ADU development in Encinitas.
Permitting Process
Securing an ADU permit involves submitting detailed plans to the City’s planning department, including site plans, floor plans, and exterior elevations. Ensuring a seamless and efficient ADU building process is crucial for timely approval and compliance with regulations.
Adherence to local building codes and zoning laws is mandatory to guarantee structural integrity and aesthetic compatibility with the neighborhood.
