ADU Construction in Pasadena
Pasadena ADUs with a step-free shower recessed into the slab at the pour, plus ember-resistant vent caps and glass on a mapped parcel. Aspenwell Construction.
A step-free shower in a Pasadena ADU bathroom is settled while the foundation forms are still going in, well before any tile is picked. To let someone walk or roll straight in, the shower floor must sit lower than the rest of the room and fall toward its drain with no curb to cross. That low pocket is shaped in the concrete itself. Missed at the pour, it can only be cut in later with a saw.
Drains laid before the concrete
Waste lines for the toilet, the lavatory and the shower all run beneath the slab, so they are placed, pitched and tested while the trench is open. An inspector sees them full of water before anything covers them. The shower pocket is formed about 2 inches below the main floor, and the reinforcing bends down through it so the slab keeps its strength at that spot. A sheet membrane lines the pocket and turns up the surrounding studs, which keeps water in the pan and the bottom plate of each wall dry for the life of the unit.
Exhaust caps and glass on a mapped parcel
Mapped fire hazard zones take in part of Pasadena, and the City of Pasadena reviews a set for a parcel inside one with ember resistance in view. In the bathroom that reaches two items. The fan duct ends at a wall or roof cap with a damper, and on a mapped lot we choose a cap built to keep embers from entering. A window beside the tub already needs safety glazing when it sits low, and inside a mapped zone every pane assembly also carries tempered glass. Off the map, the glazing rule for wet areas still holds.

ADU Construction in Pasadena: questions
Concrete placed in one piece, with thickened and reinforced edges carrying the walls, is the base we expect to draw for a Pasadena unit on firm ground. The engineer can deepen a footing under a heavily loaded post or ask for a soils report when the yard holds fill. Shower pockets and drain sleeves are formed into that same pour.
Some can. What decides it is whether the concrete beneath the old walls is deep and wide enough to anchor braced panels and to carry a new roof. We expose it at a corner and beside the door jambs. Shallow stretches get new footing sections, and the floor may be cut anyway so drain lines can reach a bathroom.
It applies to a Pasadena unit that keeps to one floor and encloses 500 square feet at most, be it freestanding, sharing a wall with the house, or framed within a garage shell. For a bathroom here, drain and shower positions are fixed on the floor plan first, and the foundation sheet follows them. Taller or roomier designs get their own figure after a lot review.
