Casita and ADU Solutions for Every Household Situation
A to Z Casita Builders offers a range of casita and accessory dwelling unit (ADU) designs tailored to different household needs. Whether a family is looking to house an elderly relative, support a young adult, or simply make better use of their property, they work with clients to find a practical solution that fits the available space and budget.
With the passage of HB 2720 in Arizona, the construction of casitas and ADUs has become more accessible. The law, which took effect on January 1, 2025, allows attached and detached ADUs to be built in cities with populations over 75,000 within one mile of central business districts. This legislation was introduced in part to address Arizona's estimated housing shortfall of nearly 300,000 units, and it opens up real opportunities for existing homeowners to expand their livable space.
Common Reasons Families Build a Casita or ADU
Multi-generational living is one of the primary drivers behind ADU construction. Many families need to provide housing for an elderly parent or grandparent who may require some level of support but still wants to maintain independence. A casita built on the same property can help bridge the gap between fully independent living and more structured care options like assisted living facilities. A to Z Casita Builders can design and build ADA-compliant casitas and ADUs to accommodate specific mobility or accessibility needs.
College students and older teens represent another common use case. First-time renters often struggle to meet the income and rental history requirements set by apartment complexes near college campuses. A backyard cottage or detached ADU on the family property can offer a more practical and cost-effective alternative. It also gives older teens a degree of independence while keeping them within reach of family support.
Supported living for family members with disabilities is another area where a casita or ADU can make a meaningful difference. Group homes and social service programs don't always meet every individual's needs. A custom-built casita on family property can be designed to match a specific level of functionality, offering a more personalized living arrangement that promotes independence while keeping family close.
Beyond family-focused uses, A to Z Casita Builders also constructs pool houses for homeowners looking to make fuller use of their outdoor space. These can be designed with open floor plans or include separate rooms, kitchens, and bathrooms depending on the homeowner's vision and lot size.
Creating a Small Family Compound
For families interested in a more connected living arrangement, HB 2720 also creates an opportunity to think strategically about property purchases. Buying two adjacent properties and building casitas or ADUs on each can create a small family compound — a more affordable alternative to the traditional large-plot compound. This approach allows families to stay close while maintaining separate living spaces.
