Pressure Washing for Apartment Buildings in Los Angeles

What an apartment building cleaning usually covers

Most apartment cleanings in Los Angeles focus on the shared spaces: the front entry and lobby approach, common walkways and stairs, the parking garage or carport, the trash enclosure, and the building walls facing the street. Private balconies and patios are usually left to tenants unless the owner decides otherwise.

Treat it as several small jobs rather than one big one. Each zone has its own kind of dirt, its own method and its own timing. Planning it that way keeps residents moving and gets a better result in each area.

Entries, walkways and stairs

These are the surfaces tenants judge the building by. Concrete walkways collect gum, drink spills, tracked-in dirt and the dark gray film that builds up under foot traffic. A rotary surface cleaner gives an even finish on flat concrete without the stripes a wand can leave. Gum needs heat or a dedicated pass, and stubborn spots may only lighten.

Stairs and landings take more care. Exterior stairs are cleaned top down so dirty water never runs over a surface that is already clean. Painted or coated steps get lower pressure, because a strong wand can lift paint and leave the stairs looking worse. Railings and stucco near the stairs are soft washed, not blasted.

Doormats, shoe racks and potted plants left outside units are the usual obstacles. Anything left in place gets cleaned around, which leaves a clean outline and a dirty square underneath, so it helps when residents clear their doorways the night before.

Garages, carports and trash areas

Parking areas collect oil drips, tire marks and fine road grime. A degreaser is applied first and given dwell time to break down the oil, then the area is cleaned with hot or warm water where it helps. Old oil that has soaked into concrete for years will usually lighten rather than disappear, and it is worth saying so to owners up front.

Trash enclosures are their own category. They hold food waste, sticky residue and odor, and they need degreasing plus a thorough rinse. Under Los Angeles Municipal Code section 64.70.02, untreated wash water from washing paved surfaces cannot be discharged into the storm drain system unless a permit allows it. In a trash area, where the water is at its dirtiest, blocking drains and collecting the runoff matters most.

Notifying tenants and scheduling around residents

Good notice prevents most complaints. Post a note in common areas and send it through whatever channel the building already uses, with the date, the time window, the areas being cleaned and what residents need to do. Usually that means moving cars out of the garage, bringing in doormats and items left on walkways, and closing windows near the work.

Timing depends on the building. Many owners prefer mid-morning on a weekday, after the commute rush and before people come home. Garages often work best in two halves, so residents always have somewhere to park. Keep at least one path to every unit open and dry at all times, and use cones or tape around wet stairs.

Building walls and the street view

Stucco is the most common exterior on LA apartment buildings, and it should be soft washed, not hit with high pressure. A mild cleaning solution is applied at low pressure, allowed to dwell, then rinsed. This lifts dirt, algae on shaded north walls, and the dust that builds up after Santa Ana wind events, without forcing water behind the stucco or etching the finish.

Faded paint, hairline cracks and stains that have soaked into the stucco will not be fixed by washing. A clean wall does make it easier to see what actually needs repair or paint, which is useful if a repaint is on the horizon.

Pricing and how often to clean

As of October 2026, our calculator rates are $0.30 per square foot for building exteriors, $0.55 per square foot for walkways, $0.25 per square foot for parking areas and concrete, and $85 per dumpster pad. Every visit has a $195 minimum. Booking two services together earns a 5% discount, and three or more earns 10%, which applies naturally to apartment jobs. The flat price is confirmed before work begins.

Many buildings do a full cleaning once a year, with entries, walkways and trash areas done more often because they get dirty fastest. Late summer or early fall, before the rainy season, is a common choice.
