About Our Interior ADUs & Additions Service
An interior ADU – also known as a Junior ADU (JADU) – is created by converting existing space within your home into an independent living unit. This could be a basement, a large bedroom, a bonus room, or any underutilized area. Interior ADUs are the most affordable and fastest option because they leverage your home’s existing structure, utilities, and roof. View ADU Builders also designs and builds home additions that expand your footprint to create a new ADU space. We manage everything from architectural plans to city permits to construction, ensuring your interior ADU meets all California building codes and local zoning requirements.
Interior ADUs & Additions — Frequently Asked Questions
What is a Junior ADU (JADU)?
A JADU is a small ADU (up to 500 sq ft) created within your existing home. JADUs must include a cooking facility and may share a bathroom with the main house. They're the fastest and most affordable ADU option.
How much does an interior ADU conversion cost?
Interior ADU conversions in Los Angeles typically cost between $80,000 and $150,000, depending on the scope of work, plumbing needs, and finishes. This is significantly less than new construction.
Can I build both a JADU and a detached ADU?
Yes! California law allows you to have one JADU plus one ADU on a single-family lot. This means you could have your main home, a JADU inside it, and a detached ADU in the backyard.
Does an interior ADU need a separate entrance?
JADUs are required to have a separate entrance from the main home. Full interior ADUs (created through additions) also typically include independent access for privacy and code compliance.
