"If you need a contractor in Grass Valley, I highly recommend Green Bee Construction. They did an incredible job adding a bathroom to our home and installing a mini-split to finish off our guest room. They are professional, easy to work with, and even helped us find a great painter and electrician. We’re thrilled with the results!"

"We have had a great rapport over the years. They know the quirks of my old home and how to fix just about anything that has been done to it (or not done to it) over the past 125 years of its existence. We have worked under a time/material agreement for smaller jobs and contracts for the larger jobs. Communication is great, they are there rain or shine and stay on the job until its done. My list has been long on getting this 'ole place fixed up and they have made it happen. I've got more to do and can't think of anyone else I would call. Thanks for the help guys!!"

"I hired Landmark construction & energy crew for a 650 sq/ft. of living room addition. Before we hired them, we already had all the necessary plans on hand including all the secured building permits with the city. When it comes to workmanship and speed, I must admit that landmark construction was very fast while investing extra attention to perfection. All the teams of workers worked fast even when it came to fixes and adjustments. They replaced the wood floor with new engineered wood flooring, repainted the entire ceiling and one living room wall and blended new stucco on the exterior wall. The new addition required new foundation, framing, and window installation. We are thoroughly content with all the work that was completed by landmark construction & energy crew. 1) they made sure to cover everything all around the working area in order to prevent damages and extra work due to paint spots and dust from all the sanding. 2) They came to work on a daily basis and few times they skipped work BUT they made sure to confirm that 2 days ahead. This was very responsible from them to do. 3) Charlie the Project Manager was available and reached all the time. When he couldn’t talk or answered, he called within the hour. In regards to pricing… the price that we got from Landmark construction & energy crew was in the middle range. Charlie came over to the house several times to discuss about the details and the process of the project, and after that he start working on the estimate."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

FAQs for addition to existing structure building service projects in Nevada City, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
