Multi-Unit Inspection in St. Paul, MN
Duplex, triplex and fourplex inspections for investors and owner-occupants across St. Paul's older housing.
A multi-unit inspection is a home inspection of a small multi-family building — typically a duplex, triplex or fourplex — covering each individual unit plus the shared systems and structure. It evaluates the same systems as a single-family inspection across multiple units, which makes it more involved and time-consuming than a standard inspection.

Why multi-unit inspections are bigger
St. Paul has a deep stock of older duplexes, triplexes and fourplexes, especially in neighborhoods like the East Side, Frogtown and Dayton's Bluff. Inspecting one means evaluating each unit — its kitchen, bath, electrical, plumbing fixtures and HVAC — plus the shared systems: the roof, foundation, common electrical service, shared plumbing, and any common laundry or mechanical room. It is several inspections in one building.
What we evaluate
- Each unit: interior condition, fixtures, the unit's heating and cooling, electrical and plumbing.
- Shared structure: roof, foundation, exterior, framing and grading.
- Shared systems: the main electrical service and metering, shared water heaters, common plumbing, and mechanical spaces.
- Safety items: egress, smoke and CO considerations, and separation between units.
Common St. Paul findings
Older multi-unit buildings frequently show aging wiring across units, galvanized supply lines, overloaded or recalled electrical, aging shared sewer laterals, and the foundation and roof concerns common to the era. A sewer scope is especially valuable since a single failed lateral affects every unit.
For investors and owner-occupants
Whether you plan to live in one unit and rent the others or hold the property as an investment, a documented condition report across all units helps you budget for repairs, capital improvements and the realities of older St. Paul multi-family housing.
Frequently asked questions
Do you inspect every unit?
Yes. A multi-unit inspection covers each individual unit plus the shared structure and systems, which makes it larger than a single-family inspection.
How much longer does a multi-unit inspection take?
Longer than a single-family inspection, since each unit and the shared systems are evaluated. Plan for additional time on site.
Is a sewer scope worth it on a multi-unit?
Especially so. A single shared lateral serves all units, so a failure affects everyone — scoping it before purchase is strongly recommended.
Can you inspect for an investor who won't occupy?
Yes. We provide the same documented condition report whether you plan to owner-occupy one unit or hold the building as an investment.
