Alon Design & Remodeling: ADU Builder Services

Alon Design & Remodeling is recognized as one of the leading ADU contractors in the country. As accessory dwelling units continue to grow in popularity among homeowners, Alon Design & Remodeling has positioned itself as an experienced ADU builder capable of handling a range of project types and sizes.

An Accessory Dwelling Unit (ADU) is an additional unit added to a residential property that functions as a fully independent living space. Unlike a simple room addition, an ADU is equipped with its own bathroom, kitchen, lighting, and all the amenities needed for someone to live there independently. They can also serve non-residential purposes, such as home offices or creative studios, depending on the homeowner's needs.

There are several reasons homeowners choose to work with an ADU contractor. ADUs can house family members, provide affordable rental income, reduce energy consumption compared to full-sized homes, and increase overall property value. These factors often help offset the initial cost of construction.

ADU Options and Project Types

When working with Alon Design & Remodeling as your ADU builder, there are several approaches to consider depending on your property and goals:

  1. Detached ADU: A standalone backyard cottage or granny flat built on the same lot as the primary residence.
  2. Attached ADU: An addition connected to the existing home, which can allow for shared plumbing and electrical systems.
  3. Garage conversion contractor services: Converting an underused garage into a livable accessory dwelling unit.
  4. Basement conversion: Transforming an existing basement into a functional living space.
  5. JADU (Junior Accessory Dwelling Unit): A smaller unit created within the existing footprint of the home.

Before starting any project, it's important to establish a clear budget and determine how the ADU will be used. The number of bedrooms, the layout, roofing choices, interior finishes, and exterior design all factor into the overall scope. Alon Design & Remodeling works with clients to understand these specifics before moving forward.

The ADU Building Process

Building an ADU involves several distinct phases, and Alon Design & Remodeling guides clients through each one:

  1. Planning: This initial phase involves setting the budget, defining the scope of work, and finalizing the design. This stage typically takes around one month.
  2. Permits: ADU construction requires specific permits and paperwork. This phase can take anywhere from 2 to 4 months depending on local regulations.
  3. Construction: Once permits are secured, site preparation and foundation work begin. The construction phase generally takes 3 to 6 months and represents the bulk of the project timeline.
  4. Finishing: Final installations and finishing touches are completed, wrapping up the project over the course of a few additional months.

The overall process — planning, permitting, building, and finishing — is straightforward in structure, though it does require patience and preparation at each stage.

It's worth noting the difference between an ADU and a guest house. Guest houses are typically not fully equipped — they may lack a kitchen or even a private bathroom. An ADU, by contrast, is designed to be fully self-sufficient, making it suitable for long-term occupancy.

From in-law suite builders to detached ADU construction and garage conversion contractor work, Alon Design & Remodeling offers a range of services for homeowners looking to add functional, livable space to their property. Adding an ADU increases the habitable square footage of a home, which is a meaningful factor in overall property value and return on investment.

"Alon Design and Remodeling did a fantastic job on my bathroom remodel. From the start, they were organized and made the whole process smooth. Alon helped me pick out materials that fit my budget but still looked high-end. The workers were respectful of my home and always kept things tidy. Every detail, from the tile work to the lighting, was done carefully and with real craftsmanship. The finished bathroom feels elegant, bright, and so much more comfortable than before."

"I highly recommend Alon Design and Remodeling Inc., The construction work craftsmanship was great and the design work had room to improve. Eli owner project manager Wilson construction team lead worked on a full remodel of our townhouse which look 2.5month from demolition to moving back in. The scope of work was extensive. The bulk of the work included removal of a load bearing wall downstairs, reconfiguration and upgrade of kitchen and master bathroom, new flooring and new paint throughout. Pros: Eli Wilson are very customer focused. When we raised issues, they listened and provided solutions fixes. They made things work within our set budget. No project is smooth sailing; their approach made this renovation less stressful. They took good care of materials hardware fixtures used in the remodeling, kept the areas outside inside cleaned and handled the relation with our neighbours well. Thank you! Cons: The design scope and process require high degree of involvement. The 3D renderings were provided so late in the process which would have caused delays if we had made design material adjustments then. We did the lighting plan recess light and other light placement is an art in itself and matched paint colours ourselves - would have loved some support there. Overall, I highly recommend Eli team. We will not hesitate to work with the team again. The take-aways are 1 where relevant, try to run interior and structural design in parallel. It was a lot of hassle to make changes downstream 2 build in lots of buffer and stay on top of everyone including your project manager to ensure all parties are aware of the deliverables."

"Project: Bathroom and Closet demorebuild Summary: Overall a good experience and I would recommend Alon if you're planning your next remodel! Lital, Eli, and the rest of the team at Alon were really nice, easy to work with, and they'll definitely be top of my list for my next project. Pros: Very communicative and got things done quickly, especially concerning permits and working with the county. Group chats were set up to coordinate everything, post pictures, and update on progress. The quality of the work was great when we settled on the right crew. The scope of the project needed to increase a bit to fix unforeseen issues and Alon handled it quickly and without any hassle. Cons: The crew that handled the beginning of the project was capable for certain steps in the process demo, framing, drywall, etc. but struggled with the attention to detail required for the finishing steps. The PM and Eli stepped in and changed crews quickly to make sure the project finished on a high note."

"We did a complete house remodel that includes windows, flooring, kitchen renovation, roof, bathrooms, master suite, painting, with garage refinish, and in a few words - it was excellent! Eli and Hen were our project managers who were very responsive, professional, and ready to help. The process was straightforward and they gave us clarification during the whole process. Also, the office team opened a group chat for us so all communications were done in one place and the process was easier than expected - not to mention that the final product is beautiful. You can't go wrong with Alon Design and Remodeling - they took care of our project from start to finish and I am glad to say that they were the right choice for the job. A highly recommended company."
