La Puente has many garages converted into bedrooms or family rooms, and more backyard ADUs are being added every year. A converted garage usually keeps the original garage slab, a few inches lower than the rest of the house and often only a step above the driveway. Flooring laid right on that slab and walls framed on it make these rooms the first place water collects.
How converted rooms take on water
- Storm runoff down the driveway and under the old garage door opening
- A water heater or washer that stayed in the room after conversion
- Water under the wall from the main house when a line breaks inside
- Condensation and moisture from a slab with no vapor barrier
How the work is handled
The extraction crew pulls standing water and the tech who does the walkthrough maps the slab and walls. Carpet, laminate and vinyl plank laid on the slab usually have to come up so the concrete can dry. Wall bottoms are checked, since the bottom plate sits right on the slab. If the water came from outside, it is handled as Category 3 and wet porous materials are removed.
Flooring glued straight to a garage slab traps moisture. The drying team meters the slab before any new flooring goes down.
ADUs and back houses
Newer ADUs are usually built on their own slab with modern plumbing, but they share the same yard grading and storm runoff. The drying process is the same. The California HCD ADU pages cover ADU rules, and Ready.gov flood guidance covers safety during storms.

See every area coveredGarage Conversion and ADU Flooding in La Puente: common questions
Why does my converted garage flood when the house does not?
The old garage slab is lower than the house floor and close to driveway level, so water reaches it first.
Does flooring on the slab have to come up?
Usually, when water got under it. Concrete cannot dry through plank, laminate or carpet pad.
Is the water from a driveway contaminated?
Runoff from outside is treated as Category 3, so porous materials it soaked are removed.
Can the room be used while it dries?
Usually not. Air movers and dehumidifiers run around the clock, and wet flooring is removed.
How long does a converted garage take to dry?
Most dry in three to five days after extraction and removal. A slab that stood under water can take longer.
Is a converted garage covered like the rest of the house?
That depends on how the conversion was permitted and reported to the insurer, and on the source of the water. Coverage depends on your policy, so it is worth checking with your own insurer.
