Detached ADUs: The Private Retreat

A detached ADU is a standalone structure, perfect for rental income or a quiet guest house.

Maximum Independence: Provides total privacy with no shared walls and independent utility options.
Flexible Placement: Can be positioned in the backyard or as a detached garage conversion to optimize your yard’s layout.
Property Equity: Standalone dwellings typically offer the highest increase in total property valuation.

Attached ADUs: The Seamless Extension

An attached ADU is built as an addition to your primary residence or as an attached garage conversion.

Integrated Living: Ideal for multi-generational housing or a home office that stays connected to the main house.
Cost Efficiency: Often more affordable by utilizing existing exterior walls and easier access to the main home’s utility lines.
Architectural Unity: Designed to blend perfectly with your home's current aesthetic for a unified look.

Build Smarter. Build Faster. Build with Urbatect.

Thousands of homeowners across California trust Urbatect to handle everything under one roof — and now, we’re helping San Jose homeowners unlock the full potential of their properties with ADUs that are as beautiful as they are functional.

Detached ADU

A Detached Accessory Dwelling Unit (ADU) is a standalone structure, built independently from your main house and any other buildings on your lot. This offers maximum privacy and flexibility, perfect for rental income, guest accommodations, a home office, or multi-generational living.

Attached ADU

While an Attached Accessory Dwelling Unit (ADU) integrates with your existing home by sharing a wall, it’s important to understand its independent nature. Unlike a simple extension, an attached ADU operates as a self-contained living space with its own private entrance. This ensures clear separation and privacy between the main house and the ADU.

Garage Conversion / Junior ADU (J-ADU) / ADU Over Garage

Your garage holds untapped potential! Converting it into a self-contained living space is a smart way to add value and flexibility to your property. Often, garage conversions fall under the category of an Accessory Dwelling Unit (ADU). When this conversion stays within the existing footprint of your single-family home, it might be classified as a Junior ADU (JADU). JADUs often have specific size limitations set by local ordinances and can be a cost-effective way to create an independent unit for family, guests, or even rental income. We can help you navigate the possibilities and determine if a JADU conversion is the right fit for your needs.

Basement & In-Law Unit Transformations

Have an underused basement or an existing in-law unit in your home? These are prime candidates for Accessory Dwelling Unit (ADU) conversions! Let us help you reimagine these spaces into comfortable, self-contained living areas. Whether you need extra income, guest accommodations, or a solution for multi-generational living, we’ll handle the design and build process to create a valuable ADU that meets local requirements.
