About Regency Builders Inc

Regency Builders Inc is a construction company serving residential clients with a focus on quality craftsmanship and reliable project delivery. Based in California, they work with homeowners on a range of building and remodeling projects, including accessory dwelling units (ADUs), which have become an increasingly important part of their service offering as demand for additional living space continues to grow across the state.

ADU Construction and Accessory Dwelling Unit Services

As an ADU contractor, Regency Builders Inc handles the construction of accessory dwelling units for homeowners looking to add functional living space to their property. Whether the goal is to house extended family, create a rental unit, or simply expand usable square footage, they work through the process from planning to completion.

Their work as an accessory dwelling unit builder covers several common ADU types, including:

  1. Detached ADUs — standalone structures built on the same lot as the primary residence, sometimes referred to as a backyard cottage or Casita
  2. Garage conversions — converting an existing attached or detached garage into a livable unit
  3. In-law suites — interior conversions or additions designed to accommodate family members
  4. JADUs (Junior Accessory Dwelling Units) — smaller units created within the existing footprint of a home

As a garage conversion contractor, Regency Builders Inc helps homeowners make use of underutilized garage space by transforming it into a permitted, code-compliant living area. This type of conversion is often a cost-effective way to add an ADU without the need for new ground-up construction.

Residential Remodeling and General Construction

Beyond ADU work, Regency Builders Inc also takes on broader residential remodeling and construction projects. Their experience spans kitchen and bathroom remodels, room additions, and other home improvement work. This general construction background supports their ADU projects, as many builds require coordination across multiple trades and construction phases.

As a licensed contractor in California, they are familiar with local permitting requirements, which is a practical consideration for any homeowner pursuing an ADU project. Navigating building codes and permit approvals can be one of the more time-consuming aspects of ADU construction, and having a contractor with relevant experience in this area can help keep a project on track.

Working with Regency Builders Inc

Regency Builders Inc positions itself as a contractor that takes a hands-on approach to project management. They work directly with homeowners throughout the construction process, aiming to keep communication clear and timelines realistic. For those considering adding a granny flat, in-law suite, or other type of accessory dwelling unit to their property, Regency Builders Inc represents one option among ADU builders operating in the California market.

Homeowners interested in ADU construction are encouraged to consult with multiple contractors to compare scope, timelines, and pricing before committing to a project.

"I built a house with Regency in 2016 and Ill be honestI was initially skeptical about builders in general. Over the years, Id heard too many horror stories and was prepared for delays, cost overruns, and surprises around every corner. But working with Regency Builders completely changed my outlook. From the start, their team especially Kevin communicated clearly, explained the timeline, and made sure we were informed at every step. During the build, I had a few last-minute updates and tweaks. Every time I asked for something, Regency gave me honest options, explained the pros and cons, and implemented changes smoothly. They were genuinely easy to work with and to come to an agreement. Even after moving in, Regency continued to impress. Whenever I had a question or a small issueno matter how minorthey responded promptly and took care of it. That kind of attentiveness has made a big difference. The craftsmanship is outstanding and after 10 years in the house I have yet to have an issue related to build quality. From the framing to the finishes, everything feels solid, thoughtfully designed, and built to last. Regency transformed what I expected to be a stressful experience into a smooth, transparent, and even enjoyable experience. They delivered on price, quality, flexibility, and customer careeverything I was hoping for and more. If you're considering a custom-built home in Southeastern Wisconsin, Id wholeheartedly recommend them."

"I built a house with Regency in 2012-2013. Best experience ever. Jon, Mike, Pat, Chad and everyone over there were awesome to work with. They made the project run smoothly, on time and met our budget. The quality of construction has stood the test of time now that we have been in our house for 12 years. And we know Regency is still there if we need a recommendation for a painter or other professional when we are ready to update our home. When we are ready to build our next home we will call Regency to do the work. Thanks to everyone there for their excellence."
