Our ADU Services

Detached ADUs

Stand-alone ADUs function as complete, independent living spaces, perfect for rental units or guest houses. These detached structures provide privacy while blending seamlessly with a property’s existing style. With full kitchens, bathrooms, and living areas, they operate as self-sufficient homes. Durable materials and thoughtful design ensure long-term value.

Attached ADUs

Attached ADUs share a wall with the primary home, making them ideal for families who want proximity combined with privacy. These additions integrate smoothly into the existing layout and architecture. They offer convenience, easy accessibility, and the feel of a separate unit without consuming additional land space.

Garage Conversion

Unused garages can be transformed into stylish, functional living units with upgraded insulation, flooring, plumbing, and electrical systems. These conversions make efficient use of existing structures while creating new opportunities for living or rental income. Proper planning ensures a comfortable, modern, and fully compliant finished space.

Basement ADUs

Basement conversions add value and space without altering the home’s footprint. A remodeled basement can become a fully functional apartment with kitchens, bathrooms, and quality finishes. With proper lighting, moisture control, and smart layouts, basements are transformed into bright, welcoming living areas suitable for long-term use.

In-Law Suites

Custom-designed in-law suites are perfect for multigenerational living, balancing independence and family connection. These ADUs feature private entrances, kitchens, and bathrooms for comfort and privacy. They provide aging relatives or adult children with secure, comfortable accommodations while keeping them close to the main household.

ADU Design & Planning

Comprehensive design and planning services cover architectural drawings, zoning compliance, and permit acquisition. Every detail is managed to ensure projects run smoothly and efficiently. With careful attention to layout, aesthetics, and regulations, the result is an ADU that aligns perfectly with both vision and requirements.

Benefits of ADUs

Increased Property Value

An ADU is a proven way to raise the resale value of your property. Buyers see additional living space as a major advantage, making a home more desirable in today’s competitive housing market. Extra square footage appeals to a wider pool of potential buyers and often results in higher offers. Over time, an ADU becomes both a practical upgrade and a profitable investment.

Rental Income Opportunities

With housing demand remaining strong, ADUs provide an attractive source of supplemental income. Homeowners can rent the unit to long-term tenants or short-term visitors, helping offset mortgage payments and improving financial stability. Consistent rental income also provides a steady return on investment, while offering flexibility if housing needs change in the future.

Housing Flexibility

ADUs provide versatile living options, whether used for aging parents, adult children, or visiting relatives. They allow families to remain close while maintaining privacy and independence for everyone. These units adapt easily as needs evolve, functioning as multi-purpose spaces that support both family life and future planning.

Cost-Effective Expansion

Compared to buying a larger home, building an ADU is a cost-effective way to gain space without leaving a neighborhood. Construction costs are typically lower than relocating, and the unit provides long-term benefits without the disruption of moving. This makes ADUs an efficient solution for expanding living space while staying within budget.

Sustainable Living

Modern ADUs are designed with energy efficiency and sustainability in mind. From low-energy appliances to eco-friendly materials, these units reduce environmental impact while lowering utility costs for homeowners. Smaller footprints also encourage efficient use of resources, making ADUs an environmentally responsible choice for forward-thinking property owners.

Enhanced Lifestyle Options

ADUs are not limited to living quarters. They can function as home offices, studios, or personal retreats. This flexibility allows homeowners to design spaces that support both productivity and relaxation. Whether used for work, creativity, or leisure, an ADU enhances daily living with convenience and comfort.
