An ADU Builder Tarzana and Reseda Families Rely On
Whether you want a modern backyard cottage on a large Tarzana lot or a smart garage conversion in Reseda, KN Remodeling builds it from the first sketch to the final walkthrough. As a licensed, insured, family-owned design-build team, we are the ADU builder Tarzana and Reseda homeowners call when they want one crew they can trust.
Along the Ventura Boulevard corridor, Tarzana's larger estate-style lots are ideal for a detached ADU. Reseda's more compact lots are often a better fit for a garage conversion or junior ADU. We know the City of Los Angeles zoning rules in both neighborhoods and plan the right type of ADU for your property.

How an ADU Builder Tarzana Team Picks the Right ADU
These two neighborhoods sit side by side, but the best ADU for each lot can be very different:
- Tarzana estate lots: Larger lots south of Ventura Boulevard often have room for a detached ADU of up to 1,200 square feet.
- Tarzana hillside streets: Sloped lots toward the Santa Monica Mountains can need grading, soils reports and fire-zone construction details.
- Reseda compact lots: Smaller lots often get the best value from a garage conversion, an attached ADU or a JADU of up to 500 square feet.
- Parking: Converting a garage into an ADU does not require replacement parking under state law.
- 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.
