The Process
Assessment
Creating an Accessory Dwelling Unit (ADU) begins with a crucial step in our three-part agreement with your San Diego General Contractor. In this phase, we evaluate the feasibility and legality of your ADU project by examining zoning laws, model code requirements, and the necessary permits. We will measure your current home and draft a basic sketch of the proposed plot plan. This comprehensive assessment is priced at $1,900 and aims to avoid expensive errors, protecting your investment as we proceed with the blueprints.
Design
Welcome to the next stage of your ADU. After confirming the feasibility of building an ADU on your San Diego lot, we'll move forward with a design contract. This crucial phase includes collaborating closely with an architect and an engineer to create detailed architectural and structural plans that comply with your property’s zoning regulations and budget. As your reliable contractor in San Diego, we handle all logistics, ensuring we acquire the necessary permits and secure city approval for your project.
Construction
To facilitate a seamless shift into the construction phase, the final step is to secure construction approval. Before commencing, it’s essential to get the city’s approval for project, ensuring the site is appropriate for the intended unit and aligns with the community’s character. Once these approvals are obtained, expect the construction process to take around 3 to 5 months, although this timeline may due to factors like site preparation. As a reliable General Contractor in San Diego, we understand that aspects such as a steep slope or demolishing existing structures can impact the overall timeline.
Completion
Our primary focus as a San Diego General Contractor is ensuring client satisfaction. We start each project with an initial inspection alongside the homeowner to pinpoint any areas that require attention. We are committed to quickly addressing any concerns related to contract compliance or particular issues. After resolving all matters obtaining approval from both the homeowner and the city, we guarantee that the ADU is fully completed and ready for use.
