ADU Construction Services by Harmony Design & Build in San Diego

Harmony Design & Build specializes in the design and construction of Accessory Dwelling Units (ADUs) in San Diego, CA. Their focus is on creating spaces that balance functionality with aesthetics, offering solutions for homeowners looking to add living space, generate rental income, or accommodate family members on their property.

San Diego's housing market remains competitive, and building costs continue to rise. For many homeowners, constructing an ADU on their existing property is a practical alternative to relocating. An ADU can serve multiple purposes — a private rental unit, a home office, a guest suite, or additional living quarters for family members — making it a versatile addition to any property.

Rental income is one of the more common reasons homeowners pursue ADU construction in San Diego. The city's universities, medical centers, and tourism industry create consistent demand for rental housing. Homeowners may choose to rent to long-term tenants or list the unit on short-term rental platforms, depending on local regulations and HOA rules.

ADUs are also frequently used as in-law suites or granny flats — providing aging parents or adult children with their own space while keeping the family close. As household needs change over time, an ADU can be repurposed accordingly, which adds to its long-term value.

From a property investment standpoint, homes with ADUs tend to attract more buyer interest and can command higher resale values, as buyers recognize the income potential and added functionality these units provide.

Types of ADUs Harmony Design & Build Constructs

Harmony Design & Build works on several types of ADU projects, each suited to different property layouts and homeowner goals:

  1. Detached ADUs (Backyard Cottages): These are standalone structures built in the backyard, complete with their own entrance, kitchen, and bathroom. As a detached ADU builder, Harmony Design & Build constructs these units for homeowners who want maximum separation between the main house and the secondary unit — whether for rental purposes or private family use.
  2. Attached ADUs: Built as an extension of the existing home, attached ADUs share a wall with the main structure. These work well as in-law suites, home offices, or additional bedrooms, and are generally a more cost-effective option than a fully detached build.
  3. Garage Conversions: Harmony Design & Build also handles garage conversion projects, transforming underutilized garage space into livable square footage. This is often one of the more affordable ADU options available to homeowners.
  4. Custom ADU Designs: For properties with unique layouts, slopes, or zoning considerations, custom ADU design allows for a tailored approach. This includes two-story units, backyard offices, or configurations designed to maximize the available lot size within local zoning rules.

It's worth noting that in San Diego, most single-family properties are eligible for at least one ADU and potentially a Junior ADU (JADU). Multi-family properties may qualify for multiple units. California has relaxed its ADU regulations in recent years, making the permitting process more accessible for homeowners.

The ADU Design and Construction Process

Harmony Design & Build follows a structured process from initial concept through to completed construction:

  1. Initial Consultation: The process begins with a discussion of the homeowner's goals, vision, and property specifics. This helps establish a clear direction before any design work begins.
  2. Design Guidance and Sketches: Their team provides design input and produces professional sketches so homeowners can visualize the layout and make adjustments before construction starts.
  3. Financing Guidance: Harmony Design & Build also helps clients navigate financing and budgeting options to make the project more manageable from a financial standpoint.
  4. Permitting and Construction: The team handles the necessary permits and approvals, managing the paperwork required by the city of San Diego. On average, an ADU project takes approximately 3 to 4 months from start to finish, depending on the type and complexity of the build.

For homeowners considering an ADU — whether a detached backyard cottage, a garage conversion, a casita, or a custom accessory dwelling unit — Harmony Design & Build offers a design-build approach that covers the project from planning through completion in San Diego, CA.

"Evy and Ofek were such a pleasure to work with. They were kind, knowledgeable, creative, and respectful of my time, budget, and home. Everyone on their team that worked on our project was great and very considerate of keeping everything organized and clean by the end of each day. I am so happy with the work they have done on my backyard, and I am definitely hoping to work with them on future projects for my home and for my familys homes."

"I wanted to start with a big project right away, but Evy suggested beginning with the outdoor project so we could get to know each other without spending a large amount upfront. I liked the idea, and just a week into the project, I already felt like I was in good hands. They were very professional, detail-oriented, friendly, and respectful! I felt confident and decided to move forward with the next project even before the outdoor one was finished. I love the new remodel and highly recommend working with Harmony!"

"At first, I started with a small concrete job in my backyard. The process was clear and transparent from the start! Ofek was very up front and understanding of my needs. Because of how impressed I was with the work Ofek and his team did. I told him about the bathroom I wanted to upgrade. He and his team were incredibly helpful. They gave me layout tips helping me making decisions about knobs, faucets, and cabinets. It was a great experience for my first remodeling project. I would highly recommend working with Harmony Design for anyone that is looking to upgrade their home in any way. It is a great way to invest in your home and raise the value of your home. Thank you"

"I had the pleasure of working with Harmony Design and Build for my recent front yard project, and I cannot recommend them highly enough. From the very beginning, all of their employees were incredibly easy to communicate with. They listened to my needs and were very attentive to the details of my vision for the space. Evy and Ofek, in particular, stood outthey were not only approachable and professional, but also genuinely willing to take the time to address my concerns and preferences. Throughout the project, they were understanding and responsive, always willing to make adjustments as needed to ensure that everything aligned with my final vision.

Having worked with many landscape contractors in both my professional and personal life, I can say with confidence that Harmony Design and Build is one of the few companies I would wholeheartedly recommend. Their commitment to quality and customer satisfaction sets them apart in the industry. If you're looking for a reliable, professional, and personable landscape team, look no further than Harmony Design and Build."
