About IEE Designs

IEE Designs: ADU and Landscape Design & Build Services in San Diego County

IEE Designs is a San Diego County-based design and build firm offering a range of services that includes accessory dwelling unit (ADU) construction alongside comprehensive exterior landscape design. Founded in 1998, the company serves residential clients across North San Diego County, with a focus on quality craftsmanship, sustainability, and attention to detail.

As an ADU contractor and accessory dwelling unit builder, IEE Designs handles projects from initial concept through to completion. Their ADU services are designed to help homeowners expand their usable living space, whether for rental income, guest accommodations, or multi-generational living arrangements.

ADU Design and Build Services

IEE Designs approaches each ADU project with a focus on local compliance and custom design. As a detached ADU builder and granny flat builder operating in San Diego County, they are familiar with the local zoning laws, permitting requirements, and regulations that govern ADU construction in the region. Their process includes managing:

  1. Lot size and zoning requirements
  2. Maximum square footage and setback rules
  3. Parking exemptions and height restrictions

Their ADU floor plans are available in several architectural styles, including Spanish, Modern, and Traditional. Each plan comes with 3D renderings to help clients visualize the finished space before construction begins. Floor plans can be customized to suit individual property layouts and lifestyle needs.

Pricing for ADU projects covers design and permitting, construction from foundation to finishes, and optional sustainability features such as energy-efficient appliances, solar panels, and water-conscious landscaping. IEE Designs positions itself as a turnkey ADU builder, managing the full scope of the project on behalf of the homeowner.

Their completed ADU projects across San Diego County have been used for a variety of purposes, including rental units, guest houses, and family living arrangements. As a Casita and in-law suite builder, they aim to deliver functional spaces that also contribute to overall property value.

Exterior Landscape and Additional Services

Beyond ADU construction, IEE Designs offers a broad range of exterior and interior plant-related services. Their landscape design and build work includes:

  1. Custom front yard and backyard design
  2. Irrigation and drainage systems
  3. Outdoor features such as fireplaces, fire pits, jacuzzis, and pools
  4. Green walls and indoor plant services for homes and offices
  5. Plant rentals and landscape maintenance

The company's design process begins with an on-site consultation, during which the team conducts site photography, takes measurements, and assesses the property. From there, they produce detailed drawings and 3D renderings before moving into construction.

IEE Designs was founded by Patty Jones, a licensed contractor with a background in industrial engineering and a long career in hardscape and landscape architecture. She has been recognized in Architectural Digest for her landscape design work. The team also includes Managing Director David Jones, who brings extensive experience in business management, and Andrea Capelli, a skilled landscape designer with nearly a decade of experience at the company.

IEE Designs received the Best of Houzz Service award for 2024, reflecting their focus on client experience and project quality. Their work spans residential landscape design, outdoor living construction, and ADU development across San Diego County.

"We recently had a patio of concrete pavers installed in our backyard, and we couldnt be happier with the results! From start to finish, the experience was smooth, professional, and enjoyable. Patty and Jorge were absolutely wonderful to work with - kind, communicative, and genuinely invested in making sure we were happy with every step of the project. Its clear this is a family business that takes pride in its work and cares about its customers. The patio turned out even better than we expected, thanks to their professional recommendations and willingness to make adjustments. If you're looking for quality work from people you can trust, we highly recommend this team. Thank you again, Patty and Jorge, for everything!"

"Im writing this review about four months after our backyard project was completed by IEED and were really enjoying the space! It offers a variety of areas for relaxing, entertaining, and spending time outdoors, exactly what we were hoping for. Working with Patty and Andie was a positive experience. The team was easy to talk to, communicated well through most of the process. They listened to our ideas, pitched some of their own and were responsive when we had questions, which made collaboration smooth and comfortable. There were a few moments where communication could have been clearer or more consistent some of the smaller details. Which is why we decided 4.5 stars was granted. Overall, were happy with how everything turned out and appreciate the work that went into bringing our vision to life. We will most definitely use them again when we are ready to work on the front of our home. Thank you Patty, Andie and team!"

"When it comes to construction projects, perhaps THE most important decision made is who you choose to work with. All contractors will be able to offer you the same or similar services and product. But how those services are performed, and product installed, certainly varies. As does the character and personality of the contractor. Before deciding to work with IEEDesigns, I interviewed several other contractors, and even interviewed specific trades to see if moving forward with the project in piecemeal fashion made sense financially and otherwise. I read reviews, looked into the records available through the Contractors State Licensing Board, evaluated the companies organizational structure, and reviewed projects completed through social media. I happily ended on IEEDesigns for several reasons. Patty, at her core, cares. She takes the time and effort to understand your design style, to not only look at the spaces in the scope of work, but other areas inside and outside of the home to make sure the design and style is cohesive. Patty was also very responsive throughout the project and made herself available not only telephonically, but in-person, too. She was responsive and adaptive, taking all my change orders in stride. Our project was fairly comprehensive for a backyard project. We removed Mexican Palms, moved retaining walls, moved the in-ground jacuzzi and overhauled the pool including new bond beams, rebuilding walls, changing from plaster to an aggregate finish, tiling, coping and adding a new waterfall feature. We even changed the elevations around the pool, building an outdoor kitchen including new gas lines, electrical, and plumbing, fireplace and separate fire pit, artificial turf, landscape drainage, irrigation, and low-voltage uplighting, pavers, and soft scape. Each person in the various trades IEEDesigns had contribute to our project was very professional. They were extremely hard workers who showed up on time everyday, 6-days a week. The detail in the work was very good. On the rare occasion something was not to my standard I.e. a surface drain was in an awkward position on a paver; or changing the style of pool skimmer cover, Id raise my concern and Patty and team addressed it without issue. Id be remiss if I didnt mention Andiewho was so amazing in assisting us with the design concept, material choices, and soft scape. Ultimately, we were very pleased with IEEDesigns every step of the way, and love the finished product. I have recommended IEEDesigns to the best of friends. Before and after photos included."

"Patty and her crew are top notch! How high? High enough to be in Architectural Digest. The designers and builders are professional and pay great attention to details. They turned my Encinitas backyard of dirt into a green oasis. My sons love spending time in our backyard now. Highly recommended!"
