Junior Accessory Dwelling Units (JADUs)

A Junior Accessory Dwelling Unit (JADU) is a smaller, more compact living space created by converting an existing room or area within the main residence, such as a bedroom or part of a garage. JADUs are limited to a maximum of 500 square feet and are designed to provide independent living with basic amenities like a kitchenette and private entrance while sharing a bathroom with the main house. They are an affordable and efficient solution to add livable space without major construction.

Why Consider a JADU?

Cost-Effective Solution

Minimal construction requirements make JADUs an affordable option for adding living space.
JADUs typically have simpler permitting processes compared to larger ADUs.

Rental Income Potential

Generate additional income by renting out the JADU while remaining within the main home.

Efficient Use of Existing Space

Utilize unused areas in your home to create a functional unit.

Flexible Housing Option

Ideal for housing family members, students, or as a guest suite.

Design and Features


JADUs are designed to maximize efficiency and functionality within a compact space. Key features include:

  • Compact Layouts: Efficient use of up to 500 square feet to include essential amenities.
  • Kitchenettes: Small-scale cooking areas with sinks, counters, and appliances.
  • Private Entrances: Ensures independence for tenants or guests.
  • Shared Utilities: Typically shares water, electricity, and sewage systems with the main house.
  • Cost-Saving Options: Lower construction and maintenance costs compared to larger ADUs.

Key Regulations to Know


Building a JADU requires compliance with specific local zoning and building codes. Important considerations include:

  1. Size Restrictions:
    • JADUs are limited to 500 square feet.
  2. Shared Amenities:
    • A JADU can share a bathroom with the primary residence, reducing construction complexity.
  3. Owner Occupancy:
    • In most jurisdictions, the homeowner must occupy either the primary residence or the JADU.
  4. Parking Requirements:
    • JADUs often have reduced or waived parking requirements, especially in areas close to public transit.
  5. Permits:
    • Zoning and safety permits are required; ADU360 simplifies this process for you.

Costs and Financing Options


JADUs are among the most affordable ADU options. Here’s a breakdown:

  1. Construction Costs:
    • Typically ranges between $10,000 and $50,000, depending on the scope of the conversion.
  2. Financing Options:
    • Home equity loans or local incentives for ADU projects are often available.
  3. Rental Income Potential:
    • Even a small JADU can provide consistent rental income, especially in high-demand housing areas.

Educational Tips for Building a JADU


  1. Identify the Right Space
    • Look for underutilized areas, such as a spare bedroom, attic, or part of a garage.
  2. Plan for Efficiency
    • Use space-saving designs like built-in storage, foldable furniture, and compact appliances.
  3. Simplify the Process
    • JADUs have fewer requirements compared to larger ADUs. Take advantage of their streamlined approval process.

Why Build an ADU in Southern California?

Southern California homeowners build ADUs for various reasons. Whether you’re considering housing family members or seeking additional income, ADUs offer flexible solutions that enhance your property’s functionality and value. Notably, a 2021 survey by Generations United found that 26% of Americans live in multigenerational households, up from 7% in 2011, indicating a growing trend toward such living arrangements. ADUs provide a practical means to accommodate this shift, offering independent yet connected living spaces for aging parents or extended family members.

Rental Income

Lease your ADU for 30 days or longer, or consider downsizing by moving into the ADU and renting out your main home!

Family Housing

Need a place for your parents or college-aged kids? ADUs provide the perfect solution for family housing!

Flexible Hosting

Whether it’s for a live-in nanny, an au pair, or friends and family visiting from out of town, an ADU creates a versatile solution for hosting.
