Why Homeowners Build ADUs

In Phoenix, AZ, homeowners often start thinking about ADUs when their existing living spaces begin to feel inadequate. This might happen when parents seek a nearby yet independent living situation, when adult children return home and desire more personal space, or when individuals plan for future rental opportunities to bolster property value. An ADU offers flexibility without necessitating a house move or major home additions. Typical motivations for building an ADU include accommodating aging relatives, creating rental opportunities with a backyard unit, building guest accommodations, converting an unused garage, or increasing property value over time. For many, an ADU proves to be one of the most valuable spaces on their property.

ADU Builder and Contractor Services in Phoenix

Stronghold collaborates with homeowners seeking a straightforward and dependable approach to constructing an ADU.

Garage Conversions

One of the Most Practical ADU Options

Transforming garages into ADUs is a prevalent option for homeowners. Since garages already comprise a structure with a foundation and roof, they serve as a logical basis for expanding into livable areas. Residents in Phoenix frequently opt for garage conversions owing to their efficient use of existing space, reduced costs compared to standalone builds, quicker completion times, and suitability as guest quarters or rental options. However, as garages are not originally designed as living spaces, enhancements to insulation, plumbing, ventilation, and electrical systems are often required. Stronghold manages these upgrades to ensure the finished space adheres to residential building codes and seamlessly extends from the home.

Understanding ADU Permits and Local Regulations

Navigating the permitting process can often take homeowners by surprise. Each city and county has its own set of requirements for constructing ADUs, which may impact the maximum allowable size, property boundaries, utility connections, parking rules, zoning policies, and associated fees. Homeowners frequently wish to commence construction right away, but the permit process can be time-consuming based on the local municipality and its review timeline. Stronghold oversees the entire permitting process from beginning to end, preparing necessary documents, submitting applications, and liaising with city reviewers and inspectors. This internal management helps minimize delays and ensures progress on projects.

ADUs for Rental Income and Multi-Family Properties

In Phoenix, many homeowners consider ADUs to optimize their property's financial potential. A thoughtfully designed backyard apartment can create an independent living unit while leveraging existing property infrastructure. Common uses for ADUs include long-term rentals, guest houses, accommodations for extended family, and secured living spaces for aging in place. Some homeowners also contemplate incorporating ADUs into larger rental or multi-family strategies. Such designs necessitate provisions for separate entrances, privacy between units, utility management, parking needs, and compliance with local rental guidelines. Stronghold partners with homeowners and investors to create lasting and adaptable ADUs.
