Your Guide to Building an Accessory Dwelling Unit (ADU) in Upland

Are you a homeowner in Upland considering adding an Accessory Dwelling Unit (ADU) to your property? Whether you’re looking to create extra living space for family, generate rental income, or increase your property’s value, the City of Upland has developed a comprehensive ADU Guidebook to help you navigate the process from start to finish.

What is an ADU?

Commonly known as granny flats, casitas, in-law units, or second dwelling units, ADUs are independent living spaces located on the same lot as a primary residence. These units provide a flexible and affordable housing solution for multi-generational families and the local workforce while also offering homeowners an opportunity for additional income.

The Upland ADU Guidebook is your step-by-step resource, covering:
Planning & Permits – Understand zoning requirements, design guidelines, and permit approvals.
Types of ADUs – Learn about different ADU styles, including detached, attached, and Junior ADUs (JADUs).
Construction & Compliance – Get insights into the building process, local and state regulations, and real-world floor plans.
Success Stories – See how other Upland homeowners have successfully added ADUs to their properties.
