ADU Construction in Valley Glen
Why window glass gets the most planning on a Valley Glen ADU, how each unit type limits where it can go, and what LADBS checks for egress and energy.
Windows and their glass are the part of a Valley Glen ADU we plan most carefully, since on any inland lot they admit more heat than the walls around them. In a small unit, one large pane facing the afternoon sun can set the cooling load for the whole space. The ADU type you choose decides how much freedom we have with placement, so glazing enters the type comparison early.
Glass placement by unit type
A detached unit can be turned on the lot so its larger openings face away from the harshest exposure, within what the setbacks allow. An attached unit has fewer walls to work with, and the shared wall carries no windows at all. A garage conversion replaces the vehicle door with a framed wall, which gives a chance to set new glass where it helps. A JADU keeps the windows the house already has, so shades or a film may be all that changes there. Each version of the window plan is drawn and compared side by side.
Glass ratings and the LADBS review
Dual panes with a low-gain coating and frames that slow heat flow lower the load on the cooling equipment. Any bedroom still needs a window big enough to climb out of in an emergency, and glass set close to a property line may need a fire rating or a smaller opening. The LADBS plan checker who takes Valley Glen drawings looks at both, and the energy forms list the glass ratings chosen. For Van Nuys, Panorama City, Sherman Oaks, Lake Balboa, Valley Village and Encino, the window plan is drawn the same way and goes to that same counter.
