Fidelity General Contractors, Inc., provides beautiful remodeling results. Your satisfaction is very important to us. We're dedicated to excellence so - let us make your house a home to be proud of!

"We had some issues with the shower pan step drainage, that they eventually fixed. However, I was not 100% satisfied with the reception I got from the PM when I initially explained the issue. I had to legally withhold any further payments until the step was repaired. I also had to revert to written communication only, in order to complete the project. Other than that small issue, we live the work they did for us."

The remodel was completed on time, and the craftsmanship exceeded our expectations. Shawn and his team made the whole experience stress-free, and I couldn?t be happier with the outcome."

"The quality of the construction was excellent. I received positive comments from home owners, and also from my architect, praising specifically the house-framing. He also hired a painter who worked closely with us and his work also came out beautiful. Actually, everyone who was hired by Ryan did great work and the whole project came out beautiful!"

FAQs for addition to existing structure building service projects in Oak View, 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.
