Frequently asked in Aurora

What are accessory dwelling units, and how do they work?

Accessory dwelling units, or ADUs, are separate living spaces on a single-family home lot. They function like a small, independent home with their own kitchen, bathroom, and bedroom. ADUs can be attached to your main house or be a separate structure in the backyard. They offer flexibility for multi-generational living or rental income.

What is the difference between an ADU and a backyard cottage?

Essentially, a backyard cottage is a type of accessory dwelling unit (ADU). The term 'ADU' is a broader category that includes various types of secondary units. A backyard cottage typically refers to a detached unit located in the backyard. Both are designed as independent living spaces on a residential property.

What does 'accessory dwelling unit' mean for homeowners?

For homeowners in Aurora, an accessory dwelling unit means adding valuable, rentable space. It's a way to accommodate family members like aging parents or young adult children. It can also be a source of rental income. This increases your property's utility and potential return on investment without needing to move.

What are prefab ADUs, and are they suitable?

Prefab ADUs, also known as prefabricated or modular ADUs, are built off-site in a controlled factory environment. They are then transported and assembled on your property. This method can often lead to faster construction times and potentially more predictable costs. They are a viable and increasingly popular option for ADUs.
