The first step to becoming an ADU is to understand your needs and plan correctly. You must think about how to use ADU – whether for family or for rent. After this, you decide the budget and gather information about the necessary permits. Once the plan is made, the construction work can be started.
Building an ADU is a big investment that requires the right guidance. Therefore, it is important to consult experienced builders. They will help you at every stage from design to construction. At the same time, they will also ensure that all the rules are followed.
Site planning is very important for ADU in Santa Monica. In this, the property is examined where ADU will be built. The slope of the ground, drainage, and electricity-water facilities are taken care of. The site plan also looks to maintain proper distance from neighboring houses and get natural light.
To create an ADU in Santa Monica, it is necessary to follow certain rules. This includes building codes, zoning regulations, and permits. ADUs have fixed height, size, and parking requirements. Non-compliance with these rules can result in fines or construction stoppages.
The design of the ADU should be such that it is both beautiful and useful. Special care is taken for the convenience of the occupants. The design is created by considering the size of the rooms, the position of the windows, and the storage space. This allows for comfortable living even in a small space.
