Welcome to SoHo Construction Company’s comprehensive guide to building an ADU in Encinitas.

What is an ADU?

In the realm of construction and real estate, the term “ADU” stands for “Accessory Dwelling Unit.” While it’s commonly known as an ADU, some may refer to it as a granny flat, casita, guest house, companion unit, granny cottage, secondary living space, or mother-in-law apartment.
An ADU is a secondary housing unit on a single residential lot. It can be attached to or detached from the main house, offering a complete independent living space with its own kitchen, bathroom, and sleeping area. ADUs provide flexible housing options for family members, renters, or as a means to generate additional income, while efficiently utilizing existing property space.

Where Can You Build an ADU in Encinitas?

In Encinitas, ADUs can be introduced on lots zoned for residential use, whether they’re single-family or multi-family. This includes properties situated within homeowners’ associations (HOAs) or even the Coastal Zone. Specific guidelines or restrictions from HOAs or local regulations in the Coastal Zone should be considered.

How Many ADUs Can You Build in Encinitas?

In Encinitas, property owners can add one Accessory Dwelling Unit (ADU) and one Junior ADU (JADU) on single-family residential lots. The JADU must be within the primary residence and comes with an owner-occupancy requirement. For multifamily lots with at least one duplex, property owners can build up to two detached ADUs. Additionally, non-livable spaces within existing multifamily buildings, such as storage rooms or garages, can be converted into ADUs.

What Types of ADUs Can You Build in Encinitas?

ADUs present a versatile array of design and construction options to fit various homeowner needs and property configurations. Popular choices include Detached ADUs, Attached ADUs, Conversion ADUs, and Junior ADUs (JADUs).

Detached A detached ADU is a standalone structure located on the same property as the main residence but completely separate from it. This type of ADU offers maximum privacy and independence, featuring its own entrance, living facilities, and often a private outdoor space. — Detached

How to Build an ADU in Encinitas?

Building an ADU in Encinitas involves a structured process to ensure compliance with local regulations and to achieve a successful project outcome. Here’s an overview of the typical steps of building an ADU with SoHo Construction:

Discovery call

Initiate your ADU project with a discovery call to SoHo Construction. This initial consultation allows us to understand your vision, needs, and goals for your ADU. We'll discuss your property, potential ADU types, and any initial questions you may have.

Feasibility Study

After the discovery call, we conduct a comprehensive feasibility study of your property. This involves evaluating local zoning laws, property analysis, and assessing any constraints that might impact the ADU project. Our goal is to determine the most suitable type of ADU for your property, considering factors like size, location, and legal requirements in Encinitas.

Design Phase

Moving forward with the insights gained from the feasibility study, our team collaborates with you to design your ADU in Encinitas. This phase includes drafting preliminary designs, refining layouts, and selecting materials that align with your preferences and budget. We ensure that the design not only meets your requirements but also complies with Encinitas's regulations for ADUs.

We handle all aspects of the permitting process, from addressing any questions from the city to ensuring that all requirements are met for a smooth approval process.

Construction

With permits in hand, we move to the construction phase. Our skilled team manages every detail of the build, from site preparation and foundation work to framing, electrical, plumbing, and finishing touches. Regular updates and open communication ensure you're informed at every stage.

Post-Construction

After passing the final inspection, you’ll receive a certificate of occupancy, allowing you to legally rent out the ADU or use it as additional living space.
