About Gannage Construction

Additional Dwelling Units On The Central Coast of California

An Additional Dwelling Unit (ADU) isn’t just an extra space—it’s an investment in your future. Whether you’re looking to generate rental income, create a private retreat for family, or increase the value of your property, an ADU provides flexibility, financial benefits, and long-term security.

At Gannage Design & Construction, we specialize in ADU construction on the Central Coast, guiding you from concept to completion with a seamless, stress-free process.

What is an ADU & Why Should You Consider One?

An Accessory Dwelling Unit (ADU) is a secondary living space on your property that can be attached (like a garage conversion) or detached (a stand-alone structure).

  1. Boost Your Home’s Value – A well-designed ADU can significantly increase your property’s worth.
  2. Earn Passive Income – Rent it out as a short-term or long-term rental and offset your mortgage.
  3. Create Multi-Generational Living – Give aging parents or adult children a private space while staying close.
  4. Work From Home – Use it as a home office or creative studio without sacrificing space in your main home.


Did You Know? Lenders can now include rental income from ADUs in a borrower’s qualifying income, thanks to a new policy from HUD via the FHA.

"Thanks to the entire team at Gannage Construction, including the subcontractors, whom did an amazing job on updating and remodeling our Airbnb! From meeting Nick, project manager, and Denise, designer extraordinaire, we instantly felt a connection to have the Gannage Team do our remodel. Communication was key for us, as we do not live in the area to do a daily check. We received pictures and updates weekly. Denise guided us through the endless design decisions with ease. Mikhail, the owner, got us to the finish line, following through with final touch ups to complete the job! We would highly recommend Gannage Construction for your remodeling projects! "

"We approached Gannage Design Construction for help with designing our remodel and additions to our home in Templeton. As a contractor, I planned to handle the construction myself, but we needed their expertise with design, permitting, engineering, and related processes. Since Gannage is a full-service design-build firm, we werent sure how they would respond to a design-only request. However, shortly after submitting our inquiry online, we received a call directly from the owner, Mikhail. He acknowledged that our request was outside their usual scope, but he was open to meeting with us and taking on the project. From our very first meeting with Mikhail and Denise at our home, they demonstrated enthusiasm, professionalism, and deep expertise. Throughout the design process, Denise was fantasticshe clearly presented all of our options and helped us understand the pros and cons of each. In the end, we had a comprehensive design that exceeded our expectations. They navigated the county permitting process efficiently and ultimately delivered a complete set of plans that we could confidently build from. Were incredibly grateful for everything they did for us. Mikhail even returned with the engineer a few times during construction to assist with framing questions, special inspections, and more. We always felt supported and well taken care of by the entire team. Thank you, Gannage Design Construction, for helping us bring our vision to life. We now have an amazing home for our family, and we truly appreciate your guidance and partnership throughout the process."

"We hired Gannage construction to do a full home remodel on our older 1970s home to make updates to our layout, siding and update a bathroom. We are very happy with Gannage. They showed up and worked everyday once the project started until the job was complete. They helped us stay in budget and we were able to see our full design on a big screen to walk through the project before we started. If you have a construction project and want to work with a trustworthy, hardworking, detailed oriented, upstanding company you should give Gannage a call."

"Mikhail and Aaron Gannage are simply the best. They conduct business honestly, openly, transparently and with integrity. We hired their team of professionals to renovate our entire house and we are doing these renovations in phases. Phase one is completed and we absolutely love it! They renovated the garage, laundry room and put new flooring and baseboards in our bedrooms and bathrooms. We fully intend to complete all the rest of our projects with Gannage! This project was not without its challenges, as every construction project encounters. Mikhail and Aaron worked tirelessly to stay within our budget and solve problems as they occurred. They are wonderful communicators. They responded to questions and concerns in a timely and patient manner. It really feels like a team when you work with Mikhail and Aaron. And I simply have to give a shout out to Denise, the best resource for finding building materials, fixtures, and deals! We saved so much money because she works so hard to find what you want at lowest price possible."
