What does it cost to pressure wash a 3,000 square foot office in San Diego?
A 3,000 sq ft commercial office exterior in San Diego runs $450 to $750 for cold-water pressure washing of stucco and concrete. Add $200 to $400 if there is a grease alley or restaurant zone requiring heated 180-degree water. BMP-compliant runoff reclaim adds $100 to $250 depending on storm drain proximity.

We quoted 23 office buildings between Mira Mesa and Chula Vista this spring. The 3,000 sq ft size came up often enough that we tracked the numbers. Property managers kept asking the same question and getting wildly different answers from competitors. The spread ranged from $280 to $1,400 for nearly identical buildings.
Here is what we charged and why.
The base price for a 3,000 sq ft exterior
Plain stucco walls and a concrete walkway. No grease, no gum, standard parking lot adjacent. Two crew, one cold-water 4 GPM rig at 3,200 PSI, surface cleaner for the flatwork, soft wash mix on the stucco. Average time: 3 to 4 hours.
That job runs $450 to $600. We charge on the lower end if access is easy and the building was washed within the last 18 months. Higher end if it has not been touched in three years and the algae is set into the stucco.
Why grease alleys double the price
The minute a building has a restaurant tenant, the math changes. Grease does not respond to cold water. It needs heat. We pull the heated rig out for grease zones, run 180 to 200-degree water at 2,500 PSI, and use a degreaser pre-spray with 10-minute dwell time.
A standard 3,000 sq ft office with a single grease alley behind a coffee tenant runs $700 to $1,100. Two restaurant tenants and the price climbs to $1,200 to $1,800. The fuel and time on the heated unit doubles our cost, and the cleanup is more involved.
Stormwater compliance and reclaim mats
San Diego enforces BMP rules under the regional MS4 permit. Wash water cannot enter storm drains. For most residential work this is barely an issue. For commercial work in a parking lot with drains every 60 feet, it is the whole job.
We carry a reclaim mat and vacuum trailer on every commercial visit. The mat goes around the drain or under the wash zone, captures runoff, and the vacuum sends it to a holding tank for proper disposal. Adds about an hour to setup and breakdown.
Property managers in Mission Valley and Sorrento Valley get fined when their vendors flush soap and grease into the storm drain. We have picked up four buildings in the last year from owners whose previous vendor cost them a city violation.
Frequency and contract pricing
One-off cleans cost more per visit. A quarterly contract on the same 3,000 sq ft office drops the per-visit price 20 to 30 percent because the building never gets bad. Algae never sets in. Grease never builds up.
Most of our quarterly commercial accounts pay $350 to $450 per visit for the building we would charge $600 to a one-time customer. Contract pricing also locks in scheduling so the work happens overnight or on weekends and tenants never see the crew.
Comparison: residential vs commercial pricing per square foot
| Property type | Cold water | Heated water | With BMP reclaim |
|---|---|---|---|
| Residential driveway | $0.15 to $0.25 per sq ft | Rarely needed | Not required |
| Office exterior | $0.18 to $0.32 per sq ft | $0.30 to $0.50 | Add $100 to $250 |
| Restaurant zone | Not effective | $0.40 to $0.80 per sq ft | Add $150 to $300 |
| Warehouse loading | $0.20 to $0.35 per sq ft | $0.35 to $0.55 | Add $200 to $400 |
What the $280 quotes are missing
When you see a quote for $280 on a 3,000 sq ft office, ask three questions. Are they capturing runoff. Are they bringing heated water for any grease zones. Are they insured for $2 million in commercial liability.
The cheap quote almost always says no to at least one. We have replaced four vendors in the last year for property managers in Kearny Mesa whose buildings were getting flushed straight into the storm drain. The city fines run $500 to $5,000 per incident.
If we cleaned your commercial property in San Diego, we would love to hear about it on Google. Mention your neighborhood and the type of work. It helps other property managers find us.
