What is a Delap Survey? 📋

A delap survey, also known as a dilapidations survey, represents a detailed assessment of a property’s condition at a specific point in time. This comprehensive evaluation examines the state of repair and identifies areas requiring maintenance, renovation, or replacement.
The term “delap” derives from “dilapidations,” which refers to the deterioration or disrepair of a property. Professional surveyors conduct these surveys to establish baseline conditions, assess compliance with lease terms, or prepare for potential dilapidation claims.
Core Components of a Delap Survey
A thorough delap survey encompasses several critical areas:
- Structural elements including foundations, walls, and roofing systems
- Mechanical systems such as heating, ventilation, and plumbing
- Electrical installations and safety compliance
- Interior finishes including flooring, walls, and ceilings
- External features like facades, windows, and landscaping
The survey process involves systematic documentation through photographs, detailed descriptions, and condition ratings for each element examined.
