What Every ADU Builder Lake Balboa Project Reviews
Lake Balboa lots are straightforward, but a few local details are worth checking early:
- Permit history: Lake Balboa was part of Van Nuys until 2007, so older permits and plans may be filed under Van Nuys. We search both names.
- Airport proximity: Homes near Van Nuys Airport benefit from extra insulation and sound-rated windows for a quieter ADU.
- Flood zone checks: A few lots near the Sepulveda Basin can fall in mapped flood areas, which can affect foundation design.
- Mid-size lots: Most lots fit a detached ADU of 500 to 800 square feet, or a garage conversion plus a JADU.
- Utilities: We decide early whether to share the main electrical panel or add a separate LADWP meter.

"I recently had the pleasure of working with KN Remodeling on adding an Accessory Dwelling Unit (ADU) to my property, and I couldn't be happier with the results. The team at KN Remodeling was professional, efficient, and extremely knowledgeable throughout the entire process. The quality of their ADU products exceeded my expectations, and the final result was exactly what I envisioned. I highly recommend KN Remodeling for anyone looking to add an ADU to their property. Thank you for a job well done!" Ching BaltazarTrustindex verifies that the original source of the review is Google. We have done two major home renovations with Nathan and his team over the last few years. They are great to work with: very professional and responsive, so when we wanted to remodel our kitchen, we trusted them with the project. They completed the work quicker than the estimated time frame and within budget. We could not be happier with the outcome and we're already planning future projects with his team. We strongly recommend KN Remodeling for any home projects you may have! Sally ChabertTrustindex verifies that the original source of the review is Google. KN Remodeling did a fantastic job on a complete remodel of our kitchen-from planning to completion, the job was seamless, on time and budget, and we are delighted with the results. Nathan had very helpful suggestions and an aesthetic eye for detail. His crew was professional, reliable, meticulous in their work, and a pleasure to have around. The entire team was courteous and very respectful of our living area and left our space tidy at the end of each work day. I wouldn't hesitate to hire them again or to recommend them to family and friends. We feel lucky to have found them. Jose PrendesTrustindex verifies that the original source of the review is Google. We took A LOT of quotes on our kitchen refresh, and Nathan was the only one who wasn't pushy or threw out high-pressure sales pitches. He listened to our concerns and approached them realistically and offered options that were doable, and not empty promises. His work teams were very professional, worked diligently, and were never rude. They took as much care of our house as we would. Even when we pointed out certain imperfections and mistakes they were quick to fix and patch up. Our kitchen was done way sooner than we had anticipated, so that's always a plus. One of the things I really liked about Nathan was that he was always a phone call away and he was very attentive to our concerns. He never dismissed us or ignored us. He cared and he never let us down. We've had experiences with other companies that have been less than favorable, and what we disliked the most was being ignored when we noticed imperfections in their work. Even today, as the kitchen is finished and Nathan came over to do final checks, we noticed our drawer hardware was rusty (it was a refresh and not a remodel), and Nathan offered to send someone over to install new ones free of charge. I would wholeheartedly recommend this company, and especially Nathan, who I found to be an honorable contractor. Ralph DavisTrustindex verifies that the original source of the review is Google. Nathan's team did two projects for us: new roof and finishing off our garage with drywall, paint and new cabinets. We couldn't be more pleased. Completely professional crew, friendly, attentive and project was completed on time. Working with Nathan was a pleasure and we would use KN again for sure. Highly recommend. HSZ33Trustindex verifies that the original source of the review is Google. I highly recommend Nathan and his team. They are Professionals who get the job done right the first time. Nathan truly cares and is very passionate about high-quality work. Thank you for a job well done. We definitely look forward to working with you again Banafsheh EsmaeiliTrustindex verifies that the original source of the review is Google. professional team, they get the job done fast, on time, with amazing results. Mr Nathan saved our unit with his professional experience and great knowledge we highly recommend him.
