The Opportunity and the Responsibility.

Adding a real dwelling to your property is a significant structural and legal undertaking. A casita is not merely an outbuilding. It requires the same rigorous planning, foundation work, utility integration, and climate consideration as a primary residence.

We help families navigate the realities of creating comfortable space for family members, visiting guests, independent living, a dedicated office, or flexible property use. DYS Construction AZ LLC approaches every addition as a permanent extension of your home.

Navigating Zoning

The Realities of Accessory Dwelling Units

While Phoenix updated Accessory Dwelling Unit regulations in late 2024, the path to building remains highly specific to your exact address. Requirements vary significantly by municipality, local zoning, existing lot coverage, property setbacks, utility access, homeowners association rules, and current property conditions.

We do not promise guaranteed eligibility, exact permit outcomes, preapproved plans, fixed schedules, or fixed initial costs. Instead, DYS Construction AZ LLC coordinates the appropriate design professionals, structural engineering, permitting, inspections, and construction when your property qualifies for development.

A Clear Path to Construction

Our process organizes the hundreds of decisions required to build a new dwelling on your property, creating a structured path from the first conversation to final inspection.

01. Property Assessment

We evaluate your lot, existing utilities, access points, and broad municipality guidelines to understand what might be physically and legally possible.

02. Design Coordination

When a project appears viable, we coordinate with architects and engineers to develop plans that respect your property lines, setbacks, and neighborhood character.

03. Scope and Planning

We review structural requirements, material selections, and necessary municipal approvals to define the scope of work and budget parameters.

04. Construction

DYS manages the complexities of site preparation, utility trenching, foundations, framing, and all city inspections through completion.

Homeowner Questions

Understanding the realities of property development.

Yes, we offer free estimates for casita projects. Utility connections, required setbacks, site access, and the proposed design all affect the cost of a casita. A property assessment helps establish the scope before an estimate can be prepared. Financing is the homeowner's responsibility.

Eligibility depends on the property's zoning, lot coverage, setbacks, and utility connections. Projects within Scottsdale require review through the City of Scottsdale; projects within Phoenix require review through the City of Phoenix. Confirm the requirements for your specific property before planning construction.

A permitted casita does not automatically establish permission for every rental use. Homeowners should confirm applicable rental and occupancy requirements with the City of Scottsdale or City of Phoenix before making rental plans. Financing and decisions about how to use the property remain the homeowner's responsibility.

A standard plan can be a starting point, but it must fit the property's setbacks, utility connections, and local code requirements. Plans still need review and permitting through the City of Scottsdale or City of Phoenix, depending on the property's location.

A typical planning range is 4 to 8 months from design to completion, rather than a guaranteed delivery date. City review, design revisions, site conditions, and utility connections can affect the schedule. The sequence should be confirmed once the property and proposed scope are understood.
