We have been serving Auburn and Sacremento Valley for more than 25 years, we specialize in ADUs) -auxillary dwelling units,- new additions, and garages. we focus on you and your project. Call today, you'll be glad you did.

"Glenn and his crews built an ADU for me in less than 3 months. His subcontractors were clean, friendly and professional. Their work was exceptional. They worked some of the hottest days of the year in July and August to ensure that the job was done in a timely manner. The job foreman was prompt to ask my opinion and ensure that my wishes were accomplished. The crews were well aware of the regulations for constructing an ADU and met the regulations in a timely manner. All permits were signed in a timely manner, inspections were scheduled in a timely manner and crews were ready and in attendance. I would definitely recommend Glenn and his crews to anyone planning projects large or small. I would hire him again for similar projects."

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