What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.

Frequently asked in Scottsdale

What exactly is an accessory dwelling unit?

An accessory dwelling unit, or ADU, is a secondary housing unit on a single-family residential lot. It's an independent living space, typically with its own kitchen, bathroom, and sleeping area. In Scottsdale, these can be attached to the primary dwelling or completely separate, offering flexibility for homeowners. They are designed to be a permanent addition to your property, not a temporary structure.

Tell me about detached accessory dwelling units.

A detached accessory dwelling unit (DADU) is a standalone structure on your property, separate from your main house. Think of it as a small guest house or casita. These are common in Scottsdale and can be built in backyards or on side yards, depending on lot size and zoning. They offer maximum privacy for occupants and are a popular choice for homeowners.

What are the downsides of building an ADU?

While ADUs offer many benefits, potential downsides include the upfront construction costs and the time involved in the building and permitting process. Homeowners should also consider potential impacts on property taxes and insurance. In Scottsdale, understanding local zoning regulations is crucial to avoid any compliance issues down the line. Careful planning with experienced professionals mitigates most concerns.

Are there any grants for accessory dwelling units in Arizona?

Currently, direct state-level grants specifically for ADU construction in Arizona are limited. However, some local municipalities or non-profit organizations may offer incentives or financing programs. It's advisable to investigate current programs available within Scottsdale or Maricopa County. We can help you explore potential avenues when you call for your estimate.

What are the requirements for building an ADU in Scottsdale?
How is an ADU typically constructed?

ADU construction can involve various methods, including traditional stick-built framing using materials like dimensional lumber and plywood, or modular construction where components are prefabricated off-site. The foundation might be a concrete slab or piers, depending on soil conditions and design. Utility connections for water, sewer, and electricity are integrated into the existing home's systems or established independently.

What does 'accessory dwelling unit' mean in practical terms?

Practically speaking, an accessory dwelling unit means you're adding a complete, self-contained living space to your property. This could be a basement apartment, an addition to your existing home, or a separate backyard cottage. In Scottsdale, it's a way to increase housing density and provide flexible living options on your lot. It's essentially a mini-home within your property lines.
