"Tal was highly recommended by a friend of mine. He came to our house with a portfolio of all the beautiful remodeling jobs he had done. He sent a detailed proposal only a few days later. We had the first floor of our home remodeled which included: kitchen, living room, dining room, family room, and powder room. We had the fireplace totally redone with an electric insert installed. We had luxury vinyl flooring installed ,the popcorn ceiling removed ,recessed lighting, and walls painted. It all looks amazing I feel like I have a new house. Tal was wonderful. He helped us pick out the flooring and the quartz countertops to complement the white shaker cabinets I chose. Everyone that was involved in the remodeling were fantastic. The workers were all very professional and were there every day, except weekends) Tal came every day to check on the progress. He let me know what was going to be done that day and who was coming to do it. Tal always answered my text messages immediately when I had questions too. It took a total of about 7 weeks. They finished on my birthday! When it is time to remodel the 2nd floor we will definitely Choose Bay Builders . (I'm hoping next year) I have recommended them to several friends and neighbors. I LOVE the 1st floor of my home now!!!!!"

FAQs for addition to existing structure building service projects in Santa Cruz, CA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
