As the housing crisis continues to grip California, innovative solutions, like a garage conversion in Costa Mesa, are emerging to address the growing demand for affordable living spaces. One such solution is the rise of Accessory Dwelling Units (ADUs), with garage conversions gaining immense popularity. These transformations are not only easing the housing shortage but also offering homeowners a chance to maximize their property’s value. In this article, we’ll delve into the world of garage conversion ADUs in Costa Mesa, exploring the benefits, regulations, and the positive impact on the community.


What is a Garage Conversion ADU?

A Garage Conversion Accessory Dwelling Unit (ADU) is a separate living space created by converting an existing garage into a self-contained unit. This ADU can be used for various purposes, including as a rental unit, a home office, or housing for family members. This creative adaptation of space allows homeowners to make the most of their property without the need for extensive construction. See an example of one our Costa Mesa garage conversions.

Benefits of Garage Conversion ADUs:

  1. Affordable Housing: Garage conversion ADUs are an affordable way to create additional housing units in Costa Mesa. These smaller spaces are often more cost-effective than building a new structure from scratch, making them accessible for homeowners with limited budgets.
  2. Property Value: Adding an ADU through a garage conversion can significantly increase your property’s value. Not only do you gain additional square footage, but the flexibility of having two separate living spaces is appealing to potential buyers or renters.
  3. Sustainability: Garage conversions are a sustainable way to repurpose existing structures, reducing the environmental impact associated with new construction. By reusing materials and minimizing waste, homeowners contribute positively to the environment.
  4. Rental Income: For homeowners in need of extra income, garage conversion ADUs can be a lucrative option. Renting out the converted space provides a consistent source of revenue, helping offset mortgage costs.

Regulations and Permits

Costa Mesa, like many California cities, has recognized the importance of ADUs in addressing housing challenges. To ensure safety and compliance, there are specific regulations and permitting processes in place for garage conversions. Here are some key points to consider:

  1. Zoning Requirements: Check with the city’s zoning department to ensure your property is eligible for a garage conversion ADU. Different zones may have different rules and restrictions.
  2. Building Codes: ADUs must adhere to building codes and safety standards. This may involve structural changes, such as reinforcing the garage’s foundation, to meet these requirements.
  3. Parking: Depending on your property’s location, you may need to provide additional parking spaces to compensate for the loss of the garage. Be sure to review the parking regulations in your area.
  4. Permitting Process: The city of Costa Mesa has streamlined the permitting process for ADUs to encourage their construction. However, homeowners must still obtain the necessary permits and inspections to ensure compliance. See more information on Costa Mesa’s ADU requirements.

A homeowner in Dana Point, CA was interested in building an Accessory Dwelling Unit in her backyard. She liked the idea of having a “granny house,” as she called it, that she could move into, while being able to rent out her main home. She chose to build out Springfield ADU Model, which has 2-bedrooms, 2-bathrooms, and 850 square feet of living space. Our team made a few custom modifications to the Springfield ADU Model in order to meet the client’s request that the unit be as “wheelchair friendly” as possible. To do this, we went ahead and swapped out the bathtub in the secondary bathroom with another walk-in, curb-less shower. We also expaneded the master shower significantly and added a shower bench and handheld shower wand. Additionally, we extended the washer/dryer area to allow for a side-by-side washer/dryer if needed. She is so excited to have her “granny house” complete and has already moved in!
