AI Agent for Property Inspections: Checklist Management and Report Generation

Build an AI agent that manages property inspection workflows, handles checklist tracking, categorizes issues from photos, and generates professional inspection reports.

Why Automate Property Inspections?

Property inspections happen at move-in, move-out, annually, and whenever maintenance concerns arise. Inspectors walk through units with a clipboard, photograph issues, and then spend an hour back at the office formatting a report. An AI inspection agent structures this workflow — generating checklists, categorizing photographed issues, and producing formatted reports instantly.

The Inspection Data Model

We start with a structured representation of inspections and their findings.

class InspectionType(Enum):
    MOVE_IN = "move_in"
    MOVE_OUT = "move_out"
    ANNUAL = "annual"
    MAINTENANCE = "maintenance"

class IssueSeverity(Enum):
    COSMETIC = "cosmetic"      # scuff marks, minor wear

@dataclass
class InspectionItem:
    room: str
    area: str  # walls, floor, ceiling, fixtures, appliances
    condition: str  # good, fair, poor, damaged

    severity: Optional[IssueSeverity] = None

Dynamic Checklist Generation

Different inspection types need different checklists. The agent generates them based on the unit configuration.

ROOM_CHECKLISTS = {
    "kitchen": [
        "Countertops", "Cabinets (open/close all)", "Sink and faucet",
        "Dishwasher", "Stove/oven", "Refrigerator", "Microwave",
        "Floor condition", "Walls and ceiling", "Light fixtures",
        "Outlets (test GFCI)", "Under-sink (check for leaks)",
    ],
    "bathroom": [
        "Toilet (flush test)", "Sink and faucet", "Shower/tub",
        "Tile and grout", "Mirror and medicine cabinet",
        "Exhaust fan", "Floor condition", "Outlets (test GFCI)",
        "Under-sink (check for leaks)", "Caulking condition",
    ],
    "bedroom": [
        "Walls and ceiling", "Floor/carpet condition",
        "Closet (doors, shelves, rod)", "Windows (open/close, locks)",
        "Window coverings", "Light fixtures", "Outlets",
        "Smoke detector (test)", "Door and hardware",
    ],
    "living_room": [
        "Walls and ceiling", "Floor condition", "Windows",
        "Window coverings", "Light fixtures", "Outlets",
        "Thermostat", "Front door (locks, deadbolt)",
    ],
}

def generate_checklist(
    unit_rooms: list[str],
    inspection_type: InspectionType,
) -> dict[str, list[str]]:
    """Generate an inspection checklist based on unit layout."""
    checklist = {}
    for room in unit_rooms:
        room_key = room.lower().split()[0]  # 'Master Bedroom' -> 'bedroom'
        base_items = ROOM_CHECKLISTS.get(room_key, ROOM_CHECKLISTS["bedroom"])
        checklist[room] = list(base_items)

    # Add move-specific items
    if inspection_type == InspectionType.MOVE_OUT:
        checklist["General"] = [
            "All personal belongings removed",
            "Unit cleaned to move-in standard",
            "All keys returned",
            "Forwarding address collected",
            "Garage/storage cleared",
        ]
    return checklist

Photo-Based Issue Categorization

When an inspector photographs damage, the AI categorizes it automatically.

Building the Inspection Agent

FAQ

Can the photo analysis detect issues that are hard to spot visually?

Vision models can identify obvious damage like cracks, water stains, mold, and broken fixtures reliably. Subtle issues like hidden water damage behind walls or electrical problems are beyond visual analysis — those still require professional inspection techniques.

How do you handle discrepancies between move-in and move-out inspections?

The system stores both inspection records linked to the same unit and tenancy period. A comparison tool diffs the two reports item by item, highlighting new damage that appeared during the tenancy. This comparison forms the basis for security deposit deduction decisions.

Is the AI-generated report legally sufficient?

AI-generated reports should be reviewed and signed by a licensed inspector or property manager. The AI handles data collection and formatting, but the human provides the professional judgment and legal accountability. Most jurisdictions accept digitally signed inspection reports.
