Custom Accessory Dwelling Units for Mountain View, CA Homeowners
Elevate Your Silicon Valley Property with a Turnkey Backyard Cottage, Luxury Rental, or Private In-Law Suite



Building an accessory dwelling unit (ADU) on your property in Mountain View, California, is a significant financial investment—one that you should only trust to a company with a proven track record for exceptional service and top-notch structural craftsmanship. You have found a partner with Sunrooms N More.
Leveraging over 23 years of specialized home improvement and structural general contracting experience—ranging from complete home additions to high-end interior structural renovations—we provide competitive local pricing on truly site-built, custom ADUs.
Bespoke vs. Prefabricated Analysis
You should never limit your property’s potential by turning to a franchise company that forces you into a highly restricted catalog of mass-produced, prefabricated ADUs. Prefab kits rarely align with Mountain View’s unique zoning guidelines, strict lot coverage maximums, or sloping backyard profiles.
At Sunrooms N More, we possess the technical engineering expertise to bring your unique vision to life successfully through high-performance, site-built construction.
To streamline your planning process, we offer a premier selection of semi-custom base floor plans ranging from efficient 500 sq. ft. open-concept models to expansive 1,200 sq. ft. multi-bedroom secondary homes. These blueprints serve as a perfect foundation that our design team can tailor to suit your unique property lines and lifestyle requirements.
As a premier custom builder, we specialize in constructing structures from the ground up. This allows for maximum spatial efficiency and creativity. You have the total freedom to choose every custom component—including custom exterior siding styles that seamlessly match your primary home, energy-efficient window packages, and high-end bathroom and kitchen finishes.
Designing and building from the ground up ensures your new unit integrates flawlessly with your existing property architecture while maintaining structural integrity and high modern efficiency. Because we have optimized our building pipelines over the last two decades, our fully custom, site-built solutions frequently cost less than the rigid pre-fabricated models offered by other builders.
Turnkey Project Management
Navigating the Mountain View Community Development Department can be an administrative headache. Sunrooms N More makes the ADU construction process completely seamless by taking total, single-source ownership of your project. You will never have to stress over coordinating or scheduling separate architects, engineers, and independent subcontractors.
Our experienced, in-house team handles every single phase:
Every aspect of your project is handled by our highly trained, full-time experts. Once we break ground, your project becomes our sole, undivided focus. We never split our attention or leave your job site half-finished to juggle other regional work, allowing us to strictly protect your timeline and guarantee immaculate quality control.

Let's Get Started
Whether you plan to use your accessory dwelling unit as a high-yield rental to offset Silicon Valley housing costs, or as a private in-law cottage or granny unit to keep extended family close, we will create the ideal secondary home for your needs and budget.
