A standard home inspection checklist was built around residential construction. A conversion building inspection requires a different frame of reference.
Original building systems
Industrial buildings built before 1950 were designed for different loads, different uses, and different standards. Understanding what's original and what was added during conversion is the first step in assessing condition.
Heritage fabric condition
Exposed brick and original timber are selling features in loft buildings. They're also maintenance challenges. An inspector experienced with heritage materials can assess the actual condition of mortar, brick face, and structural timber rather than treating them as decorative elements.
Conversion-era electrical
Buildings converted in the 1980s and 1990s often have electrical work that was installed to the code of that period. A loft inspector knows which issues are standard for that era and which represent problems that need to be addressed before purchase.
Conversion-era plumbing
Industrial buildings weren't designed with residential plumbing. The conversion-era plumbing work added those systems, and the quality varies significantly by building and contractor. Knowing where to look and what to test requires experience with these buildings specifically.
Structural bearing walls and columns
The structural elements of a converted building can't be moved, regardless of what any renovation plan suggests. An inspector who knows these buildings can identify original structural elements and flag any renovation work that's compromised them.
Common element conditions
Converted buildings often have unusual common elements: freight elevators, loading docks, original roof structures. Assessing these requires an inspector who's seen similar buildings and knows what maintenance problems to anticipate.
The best loft inspector you can find is one who has inspected dozens of buildings in the same category as the one you're buying. Their first few inspections were learning experiences. By the time they've done thirty, they know exactly where each building type tends to hide its problems.
When you ask an inspector about their conversion building experience, the right answer describes specific buildings and specific issues they've found. A vague answer about inspecting "all kinds of properties" means they haven't done enough of these to have the pattern recognition that makes the inspection valuable.
