Vacant Property Maintenance Checklist: What to Inspect Every 30 Days

Vacant properties deteriorate fast. A small roof leak becomes mold in two weeks. An unsecured window becomes a break-in overnight. An overgrown lot draws a code violation in 30 days. Whether you manage five vacant properties or five hundred, a structured monthly inspection routine is the single most effective way to prevent small issues from becoming expensive ones.

This checklist covers what should be inspected at every vacant property, every 30 days. Adapt it to your portfolio's specific needs, but don't skip any category entirely.

Exterior Inspection

• Walk the full perimeter — check for signs of forced entry, broken windows, or removed boarding
• Inspect the roof line from ground level — missing shingles, sagging, or visible damage
• Check all doors and locks — confirm securing hardware is intact and functioning
• Inspect gutters and downspouts — clogs cause water intrusion faster than most roof issues
• Check the foundation — cracks, settling, or water pooling near the base
• Look for pest activity — wasp nests, rodent holes, termite tubes, ant mounds
• Assess curb appeal — is the lawn overgrown? Are there code violation risks?

Lawn and Grounds

• Grass height — most municipalities cite at 10-12 inches; maintain well below that threshold
• Tree limbs — remove any branches touching the structure or hanging over the roof
• Fence and gate condition — verify gates are locked and fencing is intact
• Sidewalks and driveways — trip hazards, heaving concrete, or vegetation growing through cracks
• Debris — remove any trash, dumped materials, or wind-blown refuse

Interior Inspection

• Check for water intrusion — stains on ceilings, walls, or floors indicate active leaks
• Inspect plumbing — look under sinks, check toilet bases, inspect water heater area
• Test utilities — confirm what's on and what's off; verify winterization if applicable
• Check for mold — especially in bathrooms, basements, and around HVAC systems
• Verify HVAC — check filters, drain pans, and confirm system status matches season
• Look for pest evidence — droppings, nesting material, gnaw marks, dead insects
• Confirm personal property status — note any remaining items and condition

Documentation

• Take timestamped photos of every area inspected — exterior front, sides, rear, and all interior rooms
• Note any changes since the last inspection
• Flag items that need immediate attention versus routine maintenance
• Submit the inspection report within 24 hours of the visit

Common Mistakes in Vacant Property Maintenance

The most expensive mistakes in vacant property maintenance aren't dramatic — they're the quiet ones. Skipping an inspection because the property "looked fine last month." Not checking gutters because it hasn't rained. Assuming the lawn service is still showing up without verifying. Every deferred check is a bet that nothing went wrong since the last visit. Over a large enough portfolio, that bet always loses.

How Often Should Vacant Properties Be Inspected?

Monthly is the minimum standard for most servicers and asset managers. High-risk properties — those in flood zones, high-crime areas, or with known maintenance issues — may require biweekly or weekly checks. Properties approaching disposition or with active marketing should be inspected before every showing.

The cost of a monthly inspection is a fraction of the cost of a single missed issue. A burst pipe, a code lien, or vandalism damage can cost ten to fifty times what the inspection would have caught it for.
