The first step to creating an ADU is to understand your needs. You want extra space for your family or earn income from rent. ADU serves both purposes and also increases the value of your property.
There are a few important things to note when planning an ADU. Assess your space first and decide the budget. Then start the design and permit process. This will make your job easier.
Site planning is very important for ADU in Calabasas. Planning should be done keeping in mind the geographical location and rules here. Pay special attention to things like the slope of the ground, soil conditions, and water drainage. Also include parking and landscaping space in the site plan.
To make an ADU in Calabasas, it is necessary to follow certain rules. According to the building code here, the size, height and distance of the ADU are decided. There are also special rules for parking, electricity, and water connections. Following these rules will make it easier for you to get a permit.
The design of the ADU should be both beautiful and practical. It has good light and air flow. The arrangement of the rooms should be such that it gives convenience to the occupants. The roof, walls and floors are made of strong and durable materials.
Make the floor plan of your ADU according to your need. This includes the size of the rooms, the location of the kitchen, and the storage space. Position windows and doors in a way that allows light and air to flow through. You can also add outdoor spaces such as patio or balcony to the floor plan.
