Mobile and manufactured homes are a popular, affordable option in Calgary and surrounding communities — but they don't inspect the same way as a detached or semi-detached home. The construction method, foundation type, and utility systems are different, and a generic inspection can miss the issues that matter most. If you're buying a mobile home in Calgary, here's what the inspection should cover.

Mobile home vs. manufactured home

In everyday conversation, the terms are used interchangeably, but there is a technical difference. A mobile home was typically built before modern Canadian manufactured-home standards were widely adopted and transported to a site. A manufactured home is built in a factory to CSA standards (such as CSA Z240 MH) and the National Building Code of Canada, then transported and installed on site. In Calgary listings, you'll usually see them grouped together, but the age matters — older mobile homes may have ungrounded outlets, uninsulated walls, and outdated plumbing or heating systems.

Foundation and anchoring

Unlike a site-built home, a manufactured home rests on a foundation system that may include piers, blocks, tie-downs, or a permanent engineered foundation. The inspector should check for:

Levelness: Is the home sitting level, or has it settled or shifted?
Anchor straps and tie-downs: Are they present, intact, and properly tensioned?
Skirting: Is it vented properly to prevent moisture buildup and rodent entry?
Permanent foundation: If it was converted to a permanent foundation, was the work permitted and engineered?

Foundation movement is one of the most expensive issues to fix, so this is not a section to skip.

Roofing and exterior

Manufactured home roofs are often lower-slope than site-built homes and may have seams where sections were joined during transport. The inspector should look for:

Roof leaks: Especially around seams, vents, and chimney or plumbing penetrations.
Soft spots or sagging: These can indicate water damage or structural fatigue.
Exterior siding: Check for gaps, cracks, and moisture intrusion at seams.
Window and door seals: Mobile homes flex more during transport and settling, so seals can fail.

Calgary's hail and high winds make roof and exterior condition even more important.

Electrical and plumbing

Older mobile homes may have aluminum wiring, ungrounded circuits, or subpanels that were added without proper permits. Plumbing can be polybutylene (Poly-B), which insurers often flag. The inspector should confirm:

Service panel size and whether it can handle modern loads.
Presence of GFCI protection in kitchens, bathrooms, and exterior outlets.
Plumbing material and any signs of leaks under the home.
Water heater location, age, and venting.

Heating and ventilation

Many manufactured homes use a forced-air furnace that pushes heat through a belly-wrap duct system beneath the floor. This setup is different from a typical basement furnace, and the inspector should confirm the furnace is properly installed, vented, and not drawing combustion air from a confined space. Calgary winters make this a safety and comfort priority.

What a mobile home inspection is not

A standard home inspection is visual and non-invasive. It won't cover the park's infrastructure, lot lease terms, or the park's financial health. If you're buying in a land-lease community, review those documents separately. The inspection focuses on the structure and systems you own.
