Years of inspiration from @eden_housing guides my approach to helping put a dent in California’s affordable housing crisis. I was interviewed on how ADU’s are meeting the demand and had to shout out my former employer! #housing #housingcrisis #adu #adubuilder #customadu #bayarea #gc #generalcontractor

Accessory Dwelling Unit Construction & More in Sunnyvale, CA
Planners call them Accessory Dwelling Units, or ADUs. You might know them as carriage houses, caretaker quarters, casitas, cottages, garage conversions, granny flats, guest homes, in-law suites, or pool homes. Whichever name you choose, ADUs are an old idea making a big comeback! ADUs are, by definition, secondary homes on the same property as the main house that are smaller than the main house. They have their own kitchen, bathroom, and outside entrance and they can be separate from the house or attached.
Many cities are dusting off the concept of this home of a thousand names and allowing homeowners to build them by improving ordinances and development regulations, thus making it easier to build ADUs. Why? ADUs provide:
- Flexible dwelling options for the more modern family
- Housing with a smaller environmental footprint
- More affordable housing
What else? ADUs can be built to match the neighborhood’s and the homeowner’s personality. Your personality! Good design is intentional and beautiful. It should fit seamlessly into your life, your location, and your personal requirements. Good design is also intelligent. While ADUs are compact, they can be crafted to feel large, pristine, and organized.
Are you ready to add value to your property, give your kids a place to crash, add a home office, create an urban oasis, or add extra income from a rental or vacation rental? Integrum Construction has partnered up with several design teams to expedite your ADU design. From permitting and design, to giving you the keys, we can assist you with the entire process!

Say
”Here are my key takeaways from working with Sergio: He still surprises me with his quick response turnaround over text/call. He is the most responsive GC I’ve ever seen. He has a great team of sub-contractors – their work quality is great, friendly, and flexible for minor changes. Being local to Lakewood neighborhood, Sergio understands a lot about existing home's structure and working around them. As we encountered some changes in our plan, Sergio was always reasonable with making the optimal decision to minimize additional expense.
PraveenLakewood Village
”Sergio has been very knowledgeable, responsive, and reasonably priced. Because he is local, he knows the local codes really well and has been able to move really quickly on our building project. Anyone considering building or remodeling should ask Sergio for an estimate, he can give you some solid advice.
