Chino ADU Permit & Building Guide
Building an ADU in Chino is an excellent way to expand your living space, create long-term rental income, and increase the value of your property. The City of Chino offers clear ADU regulations designed to make it easier for homeowners to build legally and efficiently, while maintaining the integrity of local neighborhoods. With guidance from Apex Homes, homeowners can navigate the process with ease, from feasibility and design to permitting and construction.
ADU Regulations in Chino
Chino follows California’s state ADU law while adding local standards that define what can be built on single-family and multi-family lots. For single-family properties, homeowners may construct one detached or attached ADU and one Junior ADU (JADU). For multi-family properties, up to two detached ADUs may be added in addition to conversions of existing non-livable spaces.
Detached ADUs in Chino may be up to 1,200 square feet in size, providing ample space for a one- or two-bedroom layout. Setbacks must match those required for the main dwelling at the front of the lot, while interior side and rear setbacks are a minimum of four feet. Detached ADUs may be one story and up to 16 feet in height. Each ADU must be located at least six feet away from the primary residence to maintain safety and access requirements.
These standards offer flexibility for homeowners while ensuring ADUs blend seamlessly into existing residential areas.

The Chino ADU Permitting Process
To obtain an ADU permit in Chino, start by confirming your property’s zoning designation and selecting a design that complies with the city’s ADU standards. Choosing a pre-approved ADU plan, if available, can help streamline the review process and reduce design costs. Once your design is selected, prepare a full submittal package that includes your site plan, elevations, floor plans, structural details, and Title 24 energy documentation.
Applications are submitted through the Chino Permit Center, and if your plans meet all city requirements, permits are typically issued within two to four months. After approval and payment of applicable fees, construction may begin. Working with an experienced ADU builder like Apex Homes can further simplify this process and minimize delays.
