"THE WORST EXPERIENCE EVER! We signed a contract with Yakov to design an ADU. He raved that his engineer was on his staff as an employee and that she previously worked for LA planning so she understood how to more efficiently complete plans to be done sooner. The mistakes and time in between for her to submit corrections were so long there was no reason for it. When we were given so many excuses I contacted the city myself to get a true timeline and found that the corrections were issued by city and they were very basic items that any engineer should not have even had an issue with and weeks and over 2 months would go by that she did not respond to the corrections. When we reached out to Yakov to get resolution he brushed us off and said we had to handle it with the engineer. He did not always respond to calls. I had to excessively call them both to get the work done. It was nearly two years of stress for the plans to finally be complete and approved with the city. Suffice to say we di"

"I can not speak highly enough of Omar and LA City Builders. We started with a modest kitchen remodel, but quickly found a terrible plumbing problem that needed to be addressed before work could begin. Omar found a plumbing team that could fix our problem promptly, reasonably, and competently. After that, Omar and his crew created the most beautiful space for us. The job was done on budget (except for the unexpected plumbing issue) and on time. In this era of terrible service and lack of integrity, we were impressed that every worker that came to our job was not only competent, but they took pride in and deeply cared about the quality of work they were doing. Everyone was a true craftsman. That means everything! We are currently planning our next job for Omar and LA City Builders!"

FAQs for addition to existing structure building service projects in La Crescenta-Montrose, 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.
