Accessory Dwelling Units (ADUs) are one of the best ways to add value, living space, and rental income to a Los Angeles property. But one question comes up first for nearly every homeowner: how much does an ADU actually cost?
The three cost phases of an ADU
An ADU project generally breaks into three phases: design, permitting, and construction. Design and permitting cover the drawings and approvals that make your project buildable; construction is the physical build.
Design & plans
Custom ADU design varies with the size and complexity of your project. A faster, more affordable option is a pre-designed, permit-ready ADU plan, drafted to California and Los Angeles code and ready to build. Browse our ADU plan catalog to compare sizes, layouts, and pricing.
Permitting
Every plan must be drafted to California zoning and housing regulations. At Jayzar Designs, we handle the full filing and permitting process so you don’t have to navigate the paperwork. Learn more about our ADU design and plans service.
Construction
Build costs depend on finishes, site conditions, and size. We partner with JSN Construction to bring permitted designs to life with high-quality, custom builds.
Save with a pre-designed plan
Pre-designed plans shorten the design timeline and reduce cost, making them a practical choice for most properties. Request a free quote and we’ll prepare a proposal based on your space and goals.
