"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

Evo Turf & Evo Pavers was built with Southern California homeowners in mind, especially those tired of sky-high water bills, patchy grass, and endless yard work. Since discovering the potential of synthetic turf in 2006, we’ve been committed to transforming outdoor spaces into clean, modern, and low-maintenance environments. Our company is rooted in three pillars: product expertise, top-tier customer service, and fair competitive pricing. That’s what’s made us one of the fastest-growing landscape providers in San Diego, Riverside, and Orange Counties. As San Diego natives and lifelong friends, we take a hands-on approach: one of us will be the one answering your call, walking your property, or checking in after installation. From the first conversation to the final walkthrough, we’re here with honest advice, prompt communication, and a focus on long-term satisfaction. Considering making the switch to synthetic turf? No more mowing, watering, seeding, or chemicals. Say goodbye to bugs, allergies, pet urine spots, and brown patches, and hello to a green, beautiful yard that looks great every day of the year. Contact us for a free quote today!

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