Your Trusted NorCal General Contractor for High-ROI Property Repairs, Remodels, Additions, & ADA Accessibility

Experience the Ed Neir Difference: Quality, Integrity, Reliability, Making Your Vision a Reality

We know that your home or commercial building is more than just real estate—it's a major investment in your lifestyle and your long-term peace of mind. At Ed Neir Construction, BBB A+ rated, actively licensed general contractor, we specialize in high-ROI renovations, premium Accessory Dwelling Units (ADUs), and targeted commercial building solutions designed to maximize equity and protect your capital. Serving Northern California property owners from Yolo, Solano, Marin, and Napa Counties down to Contra Costa and Santa Clara County, we transform spaces to elevate their long-term value, utility, and market performance.

We specialize in adapting structures for your next chapter—balancing modern functionality with smart asset management. For homeowners and retirees, we craft high-quality, low-maintenance living spaces and ADUs tailored for independent retirement living, multi-generational families, or reliable passive rental income. That means we build beautiful, highly efficient spaces that make daily life easier, using smart technology and integrated design that wisely supports both your financial and personal comfort needs. For local business owners and commercial investors, we provide efficient tenant improvements (TIs), cost-effective critical repairs, and proactive ADA accessibility upgrades engineered to eliminate liability and optimize your operations.

Navigating Northern California's complex zoning, strict building codes, and permitting hurdles can prove to be an overwhelming, time-consuming, and frustrating roadblock. That's why we provide a signature, fully managed process that handles every single detail from initial design and building department approvals to the final inspection. Whether we're upgrading a residential neighborhood property or modernizing a local commercial storefront, we guarantee a transparent, fixed-price experience that respects your timeline, your budget, and your peace of mind.

Craft Your Ideal ADU: Take the First Step!

The ADU revolution is here, changing the way homeowners make the most of their property. In our local community of Vacaville, and in Santa Clara County, where we first launched our construction company, homes with an ADU – a self-contained living space on the same lot as the main house with half or less square footage – typically sell for 30% to 35% more than comparable properties without them. In California alone, ADU permits skyrocketed by over 15,000% from 2016 to 2022, with more than 83,000 units built—and the demand keeps growing.

From navigating permits to delivering a seamless build, we make the process smooth and stress-free. Whether you're dreaming of a private guest suite, a home for a loved one, or a profitable rental unit, we bring your vision to life. With Ed Neir Construction, your property isn't just a home—it's an opportunity. Let's build something great together.

I couldn’t be happier with the work they did replacing my bathroom walls and floors! From start to finish, they were professional, punctual, and incredibly easy to work with. Their attention to detail was truly impressive, and it was clear they take great pride in the quality of their work. They kept everything clean, communicated throughout the project, and made sure every detail was done right. The finished bathroom looks amazing, and I couldn’t have asked for a better experience. I highly recommend Ed Neir Construction anyone looking for honest, reliable, and skilled contractors. I absolutely love this company and will definitely use them again for future projects!

I hired Ed Neir Construction to refresh my mother's home in preparation for sale. Thanks to the diligence and professionalism of Ed and his team, we completed the refresh, listed the home, and closed with a sale price well above list, all within 4 months of start. I especially appreciate Ed's work since I live out of state. Ed kept me involved every step of the way by sending photos and calling me regularly. He made sure I was able to keep up with details, and I was overjoyed with the finished product.

I hired Ed Neir Construction to level up the living room floor to the rest of the house. I had many other projects for them to do and when I was done with all the projects for them the inside of my house was down to the studs. It took longer than I thought but we were living in the house while the work was done. Antonio and Lenny were the best, whatever we wanted done it was done. They were the best workers and Ed and the guys really did a fantastic job on the whole house. I recommend Ed Neir constitution for all your house projects. I would recommend you make a list of what you want done. The house came out unrecognizable, I was very happy.

I came home from a trip to find a water heater had failed and flooded the pantry and part of the kitchen. After the initial water heater replacement, fixing this involved coordinating service master, plumber, flooring and drywall repair. Instead I just used Ed. He was on time and on budget.
