Office Building Annual Maintenance Calendar

Office scheduling has an advantage most commercial property types lack: buildings are genuinely empty overnight and at weekends, which opens a substantial working window. The constraints are the leasing calendar, which imposes fixed tour dates, and the wet season, which limits what can be done well.

This calendar is a starting structure. Adjust it against your property's observed condition, its leasing pattern, and the microclimate notes at the end.

January – March | Late Wet Season

• Inspect drainage under load — plaza drains, structure drainage, and surface lot inlets. This is the only period that reveals whether autumn preparation worked.
• Address slip conditions promptly; arrival and departure both occur in low light.
• Entry and plaza touch-ups on a short cycle; tracked water is at its heaviest.
• Limit major cleaning to weather windows, with genuine drying margin — structures and shaded plazas dry slowly.
• Record what the season reveals: water paths, ponding, growth patterns, staining.
• Verify lighting; outages matter most now.

April – June | Spring — The Main Working Window

• The year's major cleaning belongs here. Conditions are reliable and surfaces dry predictably.
• Full pass: plazas, walkways, entries, elevations, surface lots, structure levels.
• Treat organic growth accumulated over the wet season on shaded plaza and connector sections.
• Address staining the wet season produced, including efflorescence and mineral deposition.
• Pavement work in sequence: repair, clean, seal where applicable, then stripe.
• Structure cleaning, taking advantage of reliable drying and weekend availability.
• Reassess zone frequencies against what the winter revealed.

July – September | Dry Season

• Dust and particulate management, heavier in Central Valley and near arterial roads.
• Schedule work early or late — hot surfaces cause solutions to dry before rinsing.
• Plaza seating and outdoor areas at their highest use; shorten that cycle.
• Smoking area load peaks with outdoor use.
• Use reliable conditions for work needing predictable drying: sealing, coating, striping.
• Begin watching for wildfire ash deposition.
• Position an appearance pass ahead of autumn leasing activity where the property's pattern warrants it.

October – December | Pre-Season Preparation

The highest-value and most-missed window of the office maintenance year. Work here prevents conditions rather than remediating them.

• Clear all drainage — plaza drains, structure drainage, surface lot inlets, gutters, downspouts, scuppers. The single highest-return item.
• Verify drainage functions rather than merely looks clear.
• Treat organic growth before the rains, particularly on shaded walkway sections with slip exposure.
• Clear any wildfire ash before it combines with rain.
• Repair joint sealant on plazas, walkways, and parking.
• Verify lighting comprehensively before the short days — structure levels, stair cores, employee entrance, connector walkways.
• Trim landscaping back from buildings, walkways, glazing, and drainage features.
• Confirm entry matting is adequate and in good condition for the wet season.
• Complete an appearance pass ahead of any year-end leasing activity.

Continuous Throughout the Year

• Entry and plaza touch-ups on a short cycle.
• Employee entrance and stair cores at entry-level frequency, not back-of-house frequency.
• Graffiti removal on discovery.
• Smoking area attention on a set cycle — it generates a predictable load.
• Inspection per the schedules in the Inspection Library.
• Pre-peak visual check of the arrival route, particularly after rain and in winter.
