Caine and Company: Scottsdale Casita and Guest House Builders
Caine and Company is a design-build firm based in the greater Phoenix area, serving homeowners in Scottsdale, Arcadia, and Paradise Valley. Founded over 22 years ago by Justin Caine, the company has grown primarily through client referrals — a reflection of the consistent experience they have delivered over the years. They operate as a boutique-style firm, intentionally limiting their active projects to no more than 6 to 8 at any given time to ensure each one receives adequate attention.
Their services span a range of residential construction and remodeling work, with a particular focus on custom Casitas, guest houses, pool houses, detached ADUs, and garage studio conversions. They describe their approach as straightforward — including being upfront when a project is not a good fit for their team.
ADU and Casita Construction Services
Caine and Company builds several types of accessory dwelling units and secondary structures, including:
- Guest Houses and Casitas — Separate living spaces on the property that typically include a bedroom, bathroom, and living area, suitable for guests, relatives, or renters.
- Pool Houses — Standalone structures near pool areas, often featuring changing rooms, bathrooms, lounging areas, and sometimes a kitchenette.
- Detached Garage Studio Apartments — Self-contained living spaces above or beside a standalone garage, with a compact kitchen, bathroom, and open living and sleeping area.
These structures are designed to enhance both the functionality and value of a property. Homes with ADUs can see higher resale values, and when not in use by family or guests, these spaces can serve as a source of rental income.
The process Caine and Company follows for ADU projects begins with a feasibility analysis using satellite imaging to assess the property. From there, they help determine whether the property qualifies for an ADU under local zoning and planning regulations. Because ADUs require additional permitting, they work with the relevant city or county planning departments to understand any restrictions, such as maximum square footage requirements.
Once feasibility is confirmed, their team of architects and designers collaborates with the homeowner to develop plans that reflect the intended size, layout, and functionality. After design is finalized, they manage the permit submission process. They note that permit approval typically takes between 10 to 16 weeks, depending on the location. Construction begins as soon as permits are in hand, with Caine and Company managing all subcontractors and inspection scheduling throughout.
Pricing is presented as a fixed price, lump sum contract once the design has been finalized and a proposal submitted. They offer free initial estimates and note that cost varies based on the complexity of the space, materials, structural requirements, and any changes needed to integrate the new structure with the existing property.
Design-Build Process and Team
As a design-build firm, Caine and Company handles both the design and construction phases under one roof. Their team includes interior designers, carpenters, subcontractors, and project managers who work collaboratively throughout the project. This integrated approach is intended to reduce the burden on homeowners who would otherwise need to coordinate multiple parties independently.
Designers on their team are described as college-educated professionals with experience in both timeless architectural styles and current trends. The design process for most kitchen and bathroom projects typically runs 1 to 2 months, while full home renovations or additions may take longer, particularly when permitting timelines are factored in.
Beyond ADU and Casita construction, their broader service offering includes:
- Home additions and large-scale renovations
- Kitchen and bathroom remodeling
- Custom millwork
- Exterior refresh or rebuild
- Outdoor living spaces
- Plumbing and electrical upgrades
- Sustainable luxury updates
Caine and Company serves homeowners looking for a structured, managed process from initial concept through completed construction. Their stated goal is to deliver functional, well-designed results while respecting the homeowner's time, space, and budget.
