About ADU Construction OC

ADU Construction OC – Accessory Dwelling Unit Specialists

ADU Construction OC is a company focused exclusively on the design and construction of accessory dwelling units (ADUs). Operating out of the San Clemente area, they work with homeowners looking to make better use of their property through thoughtfully built ADUs. According to the company, ADUs have the potential to improve property value by more than 20%, making them a practical consideration for many homeowners.

The company handles a range of ADU project types, including:

  1. Detached ADUs – standalone backyard cottage or granny flat structures separate from the main home
  2. Garage conversions – transforming an existing garage into a livable accessory dwelling unit
  3. Above-garage ADUs – building an additional unit above an existing garage structure
  4. Junior ADUs (JADUs) – smaller units typically created within the existing footprint of a home

As an ADU contractor and builder, ADU Construction OC positions itself as a single point of contact throughout the entire process. Rather than requiring clients to coordinate between multiple professionals, the company manages quoting, exterior and interior design, permitting, and construction under one roof.

Leadership and Experience

ADU Construction OC was founded by Jed Stamen, who brings over 30 years of experience in the construction industry. His background includes a career focused on major contemporary remodels before transitioning to specialize entirely in ADU construction. With that depth of hands-on experience, Jed leads the team with an emphasis on strategic planning and practical execution.

The company's approach centers on creating ADUs that reflect the individual needs of each client, with attention to both design and function. Each project is treated as its own unique build rather than a one-size-fits-all solution.

Common Questions About ADU Projects

ADU Construction OC addresses a number of questions that homeowners commonly have before starting a project. These include topics such as:

  1. Whether a property in San Clemente is eligible for an ADU
  2. How long the construction process typically takes
  3. What size ADU makes the most sense for a given property
  4. Whether an HOA or local jurisdiction can restrict ADU development
  5. The feasibility of building an ADU above an existing garage
  6. Parking replacement requirements when converting a garage
  7. How many ADUs can be built on a single property
  8. Whether an ADU can be used as a short-term rental

For homeowners in the San Clemente area considering an ADU — whether a detached ADU, a garage conversion, a casita-style unit, or an in-law suite — ADU Construction OC offers an initial property assessment to determine eligibility and explore the options available.

"Were absolutely thrilled with our new kitchen, thanks to Kikos incredible design and Brians outstanding contracting work! Kiko transformed our space into a beautiful, modern, and open-concept kitchen that still feels warm and inviting. The dark cabinetry, spacious counters, and large windows make it both stylish and functional. Brian and his team brought the design to life perfectly their attention to detail, professionalism, and commitment to finishing on time made the entire process smooth and stress-free. The final result exceeded our expectations! We highly recommend L Square Construction for anyone looking for top-quality design and craftsmanship."

"Brian and his team did an exceptional job designing and building my ADU! From start to finish they were basically there every step of the way - from inspection to questions being answered they were prompt and knowledgeable about the construction process and what type of finished fixtures they recommended. I cannot express how satisfied I am with my ADU, which will be used for my AirBnB business! My tenants customers will enjoy what Brian and his team created!"
