Build An ADU For Combining Households

An Accessory Dwelling Unit, or ADU, is an independent living space built on the same property as your main residence. ADUs can take the form of a detached unit, attached unit, or even a conversion of an existing structure. Here's why ADUs are the perfect solution for your additional living space needs:

1 Multi-Generational Living

ADUs provide an excellent space for elderly family members or adult children, allowing them to live independently while remaining close to their loved ones.

2 Concept & Ideas

Remaining attuned to your renovation goals, we will develop architectural concepts to evaluate the feasibility of your ideas. This stage empowers us to make necessary adjustments to the design before initiating the actual work. This proactive approach guarantees that you have the chance to refine and solidify your plans before entering the construction phase.

3 Structural Design & Permits

Upon receiving your approval for our designs, we will proceed to prepare engineering and structural plans necessary for San Diego building permits. Simultaneously, we will initiate the procurement of construction materials, taking into account your aesthetic preferences and choices.

4 Construction

Ultimately, your project seamlessly transitions from the design phase to your property! The process commences with demolition and preparatory work, progressing to the actual construction and installation of new materials. Throughout every stage, we take charge of managing all aspects of the build, ensuring you receive consistent updates on the progress.

5 Finished Project

Upon completion, we will conduct final inspections with the relevant officials to ensure compliance. We will facilitate the acquisition of the Certificate of Occupancy and necessary documentation to meet the Code of Compliance requirements.
