Are hidden rooms legal?

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.

What should be in a safe room?

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.

Does a secret room add value to your home?

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.

"I had an old refrigerator, microwave and some other things to be removed from my backyard. Robert was the original guy I I contacted. We talked pricing and then arranged a Time for pickup. Vinny was the worker that came out on time I may add he introduced himself and got straight to work it took him about not even 15 minutes to get all the stuff on the trailer. We talked for a bit and he informed me that they were a construction company that also did repairs and to keep them in mind if I ever needed anything which I will I've added them to my contact list. I think Robert and Vinny are phenomenal guys. They were both professional and friendly at the same time. I gave them five stars but that really not enough to describe how they made me feel like a special and valued customer. So this is my personal rating; 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟Satisfaction! 🤗🤗🤗🤗🤗 Friendliness! 👍🏼👍🏻👍👍🏾👍🏽👍🏿 Getting the job done! "
