How to Build an ADU in Encinitas?

Building an ADU in Carlsbad 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.

Permitting

Once the design is finalized, we'll navigate the permitting process on your behalf. This involves submitting the detailed plans and necessary documents to the City of Encinitas for approval. 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

Once construction is complete, a final inspection by the City of Encinitas is required to ensure the ADU meets all safety and building standards. 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.
