The timeline for building an Accessory Dwelling Unit (ADU) can vary based on several factors, including the complexity of the design, permitting process, and construction challenges. Generally, the process can be broken down into the following stages:
1. Design and Planning (1-3 months): This stage involves working with architects and designers to create your ADU plans and ensure they comply with local zoning and building codes.
2. Permitting (2-4 months): Obtaining the necessary permits from local authorities can take some time, depending on the jurisdiction and the specifics of your project.
3. Construction (4-8 months): The actual construction phase includes site preparation, building, and finishing the ADU. The duration depends on the size and complexity of the unit.
