A JADU (Junior Accessory Dwelling Unit) is a specific type of accessory dwelling unit (ADU) in California. It is a small, self-contained living unit that is created within an existing single-family home. The main distinction between a JADU and other types of ADUs is that a JADU is created within the existing space of the primary residence, typically by converting a part of the house, such as a bedroom or a portion of the living area.

Title 24 refers to a set of building energy efficiency standards in the state of California, United States. These standards are established by the California Energy Commission (CEC) and are part of the California Code of Regulations.

CALGreen – In an effort to preserve water quality, these techniques aim to reduce storm water runoff volume and rate. The discharge of surface water contaminants from the project site into receiving waterways can be avoided by making sure that there is no detectable increase.

CALGreen – To limit thermal bridging between materials that come into contact with steel framing and to reduce the quantity of steel that must be utilized in a steel framing system.

CALGreen – To maximize open space inside a development and to promote the use of plants whenever it is possible. The inclusion of these clauses can enhance groundwater recharge, preserve open space and wildlife habitats, and increase the carbon sink effect, which lowers greenhouse gas emissions.

CALGreen – To provide vehicle parking that satisfies local zoning requirements while minimizing the on-site space required to accommodate the required number of parking spaces. In addition, it discourages the design of parking lots larger than necessary.

CALGreen – To promote the installation and use of on-site renewable energy production that partially balances the energy consumption of a building.

CALGreen – By minimizing peak rain-water runoff, utilizing regional water quality control board mitigation measures locally, and/or utilizing other mitigation methods described above, these laws aim to promote low-impact development. Site that has grayfield or infill. In places with impermeable surfaces, rainfall needs to be managed at a slower rate than in undeveloped areas.

CALGreen – These actions are intended to cut back on indoor potable water consumption beyond the required flow rates and compliance. The state’s unstable water supply and the likelihood of future population increase and droughts, California may soon run out of water. The provisions take into account how much energy is needed to purify drinking water.
