An ADU is one of the highest-return investments a California homeowner can make—and it starts with the right design.
Choosing Sparrow Design & Plans means increasing your property value significantly with expertly crafted ADU plans. Our designs not only meet California’s building codes but also enhance the functionality and aesthetics of your property. This investment can transform your space and increase potential rental income.

Each project is a unique reflection of your ADU vision. Our team excels at creating custom ADU designs that perfectly match your specific requirements and style preferences, ensuring your space is both practical and personalized.
We take pride in our ability to bring your ideas to life—whether you’re envisioning a detached ADU for complete privacy, an attached ADU that shares a wall with your primary residence, or a garage conversion that repurposes existing space into functional living area. Your project goals may include rental income, additional family living space, or both.
Sparrow handled every step—from zoning review to permit approval. Our ADU was approved on the first submission.
A fully separate structure on your lot—up to 1,200 sq ft—providing complete privacy from the main dwelling. Ideal for rental income or a dedicated family suite.
Created within the existing footprint of your home—typically up to 500 sq ft. Lower cost and permitting complexity than a full ADU.
Shares a wall with the primary residence. Works well for homeowners who want a more connected layout while maintaining a separate entrance.
Convert an existing garage into permitted living space. One of the most cost-effective paths to adding an ADU to your property.
A standalone cottage designed for multi-generational living. Gives family members a comfortable level of independence on the same property.
Transform an underused basement into a legal, permitted dwelling unit—often the fastest path when an existing structure is already in place.
A properly permitted ADU increases property value, generates rental income, and provides flexible living space for decades to come.
From site review to permit submittal—a transparent, guided process with clear deliverables at every step.
We begin with a thorough consultation to understand your needs. Our Sacramento, CA-based team will discuss your ideas, review site challenges early, and determine the best approach for your project. We consider site conditions, budget, and your specific requirements to ensure the optimal size and functionality of your ADU.
