Junior ADU Construction San Fernando
Maximize your property's value with a sustainable footprint. We transform 500 sq. ft. of your existing home—like an attached garage or master suite—into a premium, income-generating rental for a flat-rate target of $65,000.
By utilizing eco-efficient materials and your home's current infrastructure, we deliver a turnkey San Fernando JADU that pays for itself in record time.

Note: JADUs generally require the property owner to live in either the main house or the JADU itself. Contact us for current 2026 local ordinance updates.
While JADUs offer incredible advantages, they come with specific local and state guidelines. Our team expertly navigates these rules to ensure your conversion is seamless and compliant.
JADUs are limited to a maximum of 500 square feet and must be at least 150 square feet. This makes them perfect for converted master suites or garages.
Requires a sink, a cooking appliance, and a refrigerator. Note: 240V stove outlets are typically not required, keeping electrical upgrades minimal.
A key distinction: The property owner must occupy either the main dwelling or the JADU. This is a vital legal requirement for 2026 JADU compliance.
JADUs are often exempt from additional parking and can share utilities with the main house, significantly reducing your initial investment.

We design "plug-in" ready kitchenettes that meet the San Fernando building code—requiring a sink, a clear working surface, and a small refrigerator without the need for expensive 240V heavy-duty stove wiring.
A JADU is the only unit type allowed to "share" a bathroom with the main house. However, for maximum rental value, we can often reconfigure existing plumbing to create a private, dedicated bathroom within the 500 sq. ft. limit.
To meet San Fernando JADU requirements, the unit must be contained within the existing walls of your home and not exceed 500 square feet. For official state guidelines, you can reference the California HCD standards.
