About Optivest Build

About Optivest Build

Optivest Build is a licensed general contracting and construction management company focused on delivering residential and commercial projects. Their work spans new construction, renovations, and accessory dwelling units, combining craftsmanship with structured project oversight to bring client visions to completion.

Their process follows a clear path: an initial consultation to understand the client's goals and budget, followed by design and build phases where the team manages permits, timelines, and quality control, and finally a completion and handover stage that includes final inspections before the client takes possession.

ADU Services

As an ADU contractor, Optivest Build provides end-to-end accessory dwelling unit solutions, covering design, permitting, construction, and finishing. An accessory dwelling unit can serve a range of purposes — rental income, a private guest space, or an independent living area for family members. Their team works to ensure each ADU integrates well with the existing property.

Their ADU offerings include:

  1. Detached ADUs — Stand-alone units built on the same property as the main home, offering a high degree of privacy and flexibility for use as a backyard cottage, granny flat, or Casita.
  2. Attached ADUs — Units connected to the main residence, adding living space while maintaining proximity to the primary home.
  3. Garage Conversions — As a garage conversion contractor, Optivest Build transforms existing garages into fully functional living units with custom layouts and quality finishes.

As a detached ADU builder and granny flat builder, Optivest Build manages all phases of the project — from initial design through final inspection — with the goal of keeping the process straightforward for the client. They offer free consultations and estimates to help property owners make informed decisions before committing to a project.

Key aspects of their ADU approach include:

  1. Use of quality materials and skilled workmanship for durable, functional results
  2. Complete project management from planning through final inspection
  3. Custom layouts and finishes tailored to the client's lifestyle and budget
  4. Transparent pricing and clear timelines with no hidden costs
  5. Compliance with local building codes throughout the process

Additional Construction Services

Beyond ADU work, Optivest Build offers a broader range of residential and commercial construction services:

  1. Whole-Home Renovations — Full-scale renovations addressing aesthetics, functionality, and property value
  2. Home Additions — Adding bedrooms, expanded living areas, or second stories to existing homes
  3. New Construction — Custom residential homes, commercial properties, multi-unit developments, and ground-up custom builds
  4. Kitchen Remodeling — Updated layouts, custom cabinetry, and quality finishes
  5. Bathroom Remodeling — Functional and stylish bathroom upgrades
  6. Basement Additions & Garages — Custom builds designed for utility and added property value
  7. Home Improvements — Minor upgrades through to more significant repairs and fixes

"We are almost done with our addition in basement and remodel project, and the experience was outstanding from start to finish. Moe and the team were professional, detail-oriented, and consistently kept the project on schedule despite several structural challenges. Their workmanship and communication exceeded expectations from foundation and framing all the way to final finishes. Every step was handled with care and transparency. The final result completely transformed our home and reflects true quality craftsmanship. We highly recommend this team for any remodel or construction project!"

"We hired Optivest Build to construct an ADU for my parents. After collecting quotes from several contractors, we chose them because of their cost-efficient proposal. We were also impressed by the manager, Moe, whose strong background with a PhD in Construction, assured us of the company's technical knowledge and expertise. We are nearing completion on the project and have been extremely satisfied with the work. Moe and his team are exceptional at managing the budget, working diligently to keep costs in a reasonable range without sacrificing quality. The construction team has been professional, polite, and consistently keeps the job site clean and organized, which has minimized the disturbance to our property and neighbors. I highly recommend them for anyone looking for a high-quality and budget-conscious contractor."

"We wanted to make some changes and adjustments to the new house we purchased recently. Before moving in, Moe and his team gave us a lot of good suggestions and helped us to make all ideas we had in mind possible. They even pointed out and fixed some of the issues that we were not aware of. They can cover any type of work from landscaping, structural framing, electrical and plumbing, up to fine finish work and adjustment. We even had a very large chandelier to be installed on 20 feet ceiling and they helped us with that too. We are planning to work with them to build an ADU as well which his team is helping us to finish as a turn key project from permitting to complition."

"We asked Moe to help us with preparation of our house that needed some paint and fixes reported in the inspection report to get it ready to be listed in the market for sell. We had a very tight timeframe as we were on the escrow for the new house we were moving to and we needed to wrap up things quick and clean. Moe and his crew were very supportive and helped us to wrap up things with high quality and fast. I am glad to say that we could manage our situation with their help, and for sure very happy to work with them in future again."

"We had our kitchen remodeled and hardwood floors installed, and the team did an excellent job. Overall, it was a fantastic experience working through this project. They listened to us throughout and were very open to the small changes we made along the way. Their patience made the process much less stressful and helped us feel confident in our decisions. The craftsmanship was high-quality, communication was clear, and everything was completed right on schedule. We highly recommend their work!"
