Calcons – ADU Contractor in Los Angeles, CA

About Calcons

Calcons is a construction company that specializes in accessory dwelling units (ADUs) and related residential construction services. Based in California, they work with homeowners looking to add living space to their properties through a range of ADU solutions.

ADU Construction Services

As an experienced ADU contractor, Calcons handles projects from the ground up. Their services cover the full scope of ADU development, including detached ADU construction, garage conversions, and junior accessory dwelling units (JADUs). Whether a homeowner is looking to build a backyard cottage, a granny flat, or convert an existing structure into a livable space, Calcons manages the process from planning through completion.

Garage conversion projects are a common request, and Calcons works as a garage conversion contractor to transform underutilized garage space into functional living quarters. This type of project can be a cost-effective way to add a rentable unit or additional space for family members without the need for new ground-up construction.

What Calcons Offers

Calcons approaches each project with attention to local building codes and permit requirements, which are particularly important in California given the state's evolving ADU regulations. Their work as an accessory dwelling unit builder includes:

  1. Detached ADU construction
  2. Attached ADU additions
  3. Garage conversions to living space
  4. Junior ADU (JADU) buildouts
  5. In-law suite construction

Each of these project types requires careful coordination between design, permitting, and construction phases. Calcons takes on that coordination as part of their service, helping homeowners navigate what can otherwise be a complex process.

For those interested in a Casita or a standalone backyard cottage, Calcons can work with the homeowner to determine what is feasible on a given lot, taking into account setback requirements, utility connections, and local zoning rules.

Working with Calcons

Calcons positions itself as a hands-on ADU builder that manages the construction process directly. Their focus on ADU projects means they have familiarity with the specific challenges these builds present, including site constraints, structural considerations, and the need to minimize disruption to the existing property.

Homeowners considering an ADU — whether as a rental unit, a space for aging relatives, or simply additional square footage — can look to Calcons as a contractor with relevant experience in this area of residential construction.

From day one, Ed was a pleasure to work with honest, easy to talk to, and clearly very knowledgeable about both design and construction. The projects were handled smoothly from start to finish, and the results turned out better than I expected.
