A Studio City addition is two different jobs depending on which half of the neighborhood the house sits in. In the flats around Tujunga Village and Colfax Meadows, mid-century homes on compact lots usually add a primary suite or family room at the rear, and the constraint is floor area, not slope. In the hills of Fryman, Laurel and Coldwater Canyons, an addition is engineered for the slope first — foundations, retaining, drainage and access — before any floor plan is drawn.
Studio City is part of the City of Los Angeles, and the zoning code’s setbacks, height and floor-area ratio decide how much can be built. Parts of Studio City also carry residential floor-area limits that cap additions on smaller lots, and hillside parcels fall under the Baseline Hillside Ordinance. We check every applicable limit for your parcel at the feasibility visit.

Read the Sherman Oaks room addition guideFeasibility, design and engineering come first, then LADBS plan check — whose timing varies with the season and the design. Construction of a flat-lot addition runs several months once started; canyon work takes longer for foundation and site stages. You receive a written, phased schedule before anything is demolished.
“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!”
