Calabasas is one of the better places in Los Angeles County to build an accessory dwelling unit. Lots are generally larger than in the Valley flats, many homes already have a detached or oversized garage, and the reasons families build here are practical: a parent moving in, an adult child who grew up in Calabasas and wants to stay, a guest house for visiting family, or a home office and studio that is genuinely separate from the main house. The complications are also specific to Calabasas — hillside lots, wildfire-zone construction standards and homeowner-association design review — and they need to be understood before the first drawing.
American Reliable Construction & Remodeling designs and builds ADUs in Calabasas from our Sherman Oaks office, about twenty minutes down the 101. We start with a feasibility visit to your property, then handle design, the City of Calabasas permit process, any HOA architectural submittal, utility connections, construction and final inspection under one license and one written scope.
American Reliable Construction & Remodeling, Inc. is a licensed California general contractor (CSLB #1155602), bonded, insured and BBB Accredited. Warranty available. Call for details.
Feasibility and design take a few weeks; City of Calabasas plan check and any HOA review follow and vary with the design and the season. Construction of a detached ADU typically runs several months; a garage conversion is shorter. You receive a written schedule and a single point of contact from the first visit to the certificate of occupancy.
“We recently completed a room addition along with a full roof customization, and the results are amazing. The team was professional, organized, and easy to communicate with throughout the entire project. The new room looks like it has always been part of the house, and the new roof was installed perfectly. Highly recommend their services!”
“I didn't think a bathroom could make that much of a difference until this one was finished. We kept the design pretty timeless with a walk in shower, porcelain tile, and a wood vanity, and it completely changed the feel of the space. It feels cleaner, more open, and just a lot more enjoyable to use every day.”
“Great experience with American Reliable Construction & Remodeling. They helped us with our ADU from start to finish and made the whole process smooth and stress-free. The team was professional, responsive, and delivered quality work. Highly recommend!”
We'll visit the property, answer the permit and layout questions, and put a written, itemized estimate in your hands — free, no obligation.
Under state ADU law, most single-family lots in Calabasas can have at least one ADU, and the City processes ADU applications routinely. Hillside slope, fire-zone requirements, septic or utility constraints and HOA design review are the usual complications. We review all of them at a free feasibility visit before you spend money on design.
