"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."

You will not be disappointed; we do large or small projects. We also specialize in building new custom homes, and complete remodels. Call us at (714) 981-5729 Newland Construction, Inc., today!

"My husband and I had several appointments with different contractors. When we met with Terry, we both felt he was very knowledgeable in all areas, and had very good pricing. Needless to say, we chose Newland Construction. From day one, we felt comfortable and at ease. Renovation Project: 1. Moved the small kitchen to our large dining room. 2. Moved dining room to former kitchen ( swapped rooms) 3. Dining room: (former kitchen) removed wall for open concept 4. New flooring 5. Stairs: replaced carpet with laminate, replaced rails 6. Living room: Added a window seat with storage 7. Living room: Added entertainment wall with shelving 8. Living room: Added modern fireplace 9. Added windows, moved sliding glass door WE LOVE THE FINISHED PRODUCT!! The project was right on schedule (5 months) and we didn't go over budget. As it is expected to run into a few snags during ANY renovation, Terry and John were very responsive and quick to resolve any issue. They were on top of the problem, and resolved with excellent results. We get a ton of compliments on our home. Thank you, Terry, John and your crew. You've exceeded our expectations. Highly recommended!!"

"This is our second project with Horizon Construction & Remodeling. They originally remodeled our primary bathroom. They did such an excellent job with that, so we brought them back to remodel our kitchen and upgrade our electrical panel. We had a good idea of what we wanted, but Mark helped walk us through our design. He made several suggestions that helped improve our design and function in the kitchen. The staff that did the work were extremely polite and professional. They cleaned up after each day of work and were overall respectful of our property. They showed up when they said they would be here. Not only does everything look great, but the quality is also wonderful! As our house was built in 1958, we did find problems with the plumbing for gas and water. We needed to replace all the lines, so we had the whole house replumbed.

FAQs for addition to existing structure building service projects in Aliso Viejo, CA

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
