Buying a Multi Unit or Mixed Use Building in the North Okanagan: A Buyer’s Guide

A four plex is not a big house. It looks like one on the listing, and a lot of first time investors walk it the way they would walk a house. But the moment a building has more than one household under one roof, the failure modes change. One boiler heats everybody. One roof covers everybody. One sewer lateral carries everybody’s waste to the street. When a shared system fails, it fails for every door at once, and the owner is the one who answers the phone.

This guide is for buyers and their agents looking at the multi unit stock across Vernon, Coldstream, Armstrong, Enderby and the rest of the North Okanagan: four plexes, walk up apartment buildings, and the main street buildings with retail below and suites above. It covers what a commercial inspection of a multi unit building deals with that a house inspection never does, and what it cannot see with tenants in place.

One of everything, serving many doors

Start with the shared systems. In a walk up of any age there is usually one heating plant, a boiler feeding radiators or a hydronic loop in older stock, a central rooftop unit serving corridors in newer stock. A boiler with a corroded heat exchanger or a relief valve weeping onto the floor is a building wide problem waiting for the first cold week in November.

One electrical service feeds everything, and the total is fixed no matter how many suites want a heat pump or an EV charger. One roof covers every unit, and a low slope membrane over a walk up has the same drain, parapet and ponding problems as any commercial roof, with the twist that the top floor tenants find the leak first and are the least likely to report it.

The sewer lateral is the one people forget. A single lateral carries every toilet, every kitchen sink and, in a mixed use building, the restaurant’s grease. In the older main street stock in Vernon, Armstrong and Enderby that lateral is often original cast iron or clay, decades past the point where its interior has roughened and narrowed. A backup in a four plex is four households displaced. c4u documents visible drain material, cleanout locations, staining at floor drains and evidence of past backups, and recommends a camera scope by a drain contractor where the age or the evidence warrants it. The inspection tells you whether to pay for that scope; it does not include it.

Getting in: tenants, notice and who arranges what

Tenants have a right to be in their homes undisturbed. The principle under BC’s residential tenancy rules is that a landlord may enter a rented unit only with proper written notice given a reasonable time ahead, at a reasonable hour, for a legitimate purpose, and an inspection for a sale is one. The landlord here is the vendor. The buyer has no standing to contact tenants or arrange entry, so the whole exercise runs through the vendor or the property manager, and it has to start at acceptance, not the week before subjects come off. Commercial tenants are governed by their leases, and a restaurant kitchen is not a place to inspect at noon.

This is the biggest driver of schedule in a multi unit purchase, covered in more depth in the post on how long a commercial due diligence period actually needs to be. Every suite is a separate appointment somebody else has to arrange, and the buyer’s window is running the whole time.

Every suite, or a sample

With tenants in place, buyers are sometimes offered a sample: the inspector sees three of eight suites and the vendor calls the rest representative. Full access is the standard to aim for. Sampling is a compromise, and if it is accepted it should be a written, deliberate decision by the buyer, with the unseen suites listed as not inspected in the report, not a quiet default because two tenants did not answer the door.

What sampling misses is exactly what costs money. One suite with a slow leak under a bathtub that has been rotting the subfloor and staining the ceiling below. One suite where a previous tenant added a wood stove without a permit or a proper chimney, which is not rare in the north end of the valley. None of these show from the corridor, and none are visible in the three suites the vendor chose to show.

If a sample is unavoidable, the buyer should choose it for the worst case: the top floor suites under the roof, the lowest suites where moisture shows up, and any suite the vendor’s disclosures mention. The mechanical room, the electrical room, the roof, the laundry and the parkade are never sampled. They are the building.

Common areas: the owner’s liability, not the tenant’s

Inside a suite, a tenant’s habits are mostly their problem. In the common areas, everything is the owner’s, and that is where life safety lives.

Egress first. Every storey needs its exits, and the exit doors need to open without a key from the inside. Fire separations between suites and corridors, and between the retail occupancy and the residential floors above, depend on rated doors that close and latch on their own. Closers get removed because they slam, doors get propped, and both undo the separation. Exit signs and emergency lights have test buttons and the inspector presses them. Extinguishers carry a dated inspection tag. The fire alarm panel, where there is one, should show normal with no trouble lights and have a current annual inspection record, and a corridor with no alarm of any kind is a finding in itself.

Then the ordinary things that hurt people: stair treads and handrails, guard heights, exterior stairs that ice up on the north face through the shoulder seasons, walkways heaved by freeze thaw. c4u documents all of this with photographs, notes missing or expired tags and refers testing and certification to a fire protection contractor. It does not certify systems. It tells you what is there and what is not.

Laundry and parkade

Shared laundry rooms concentrate water, heat and gas in one room that nobody owns. Dryer vents packed with lint or terminating inside a ceiling space, gas connectors that have seen better decades, floor drains that are dry or missing, supply hoses never changed and shutoffs that no longer turn.

A parkade under the building is a different order of exposure. It carries vehicles, snowmelt and road salt onto a suspended slab, and in the Okanagan it does that through months of freeze thaw. c4u looks at the underside of the slab and the beams for staining, efflorescence, spalling and exposed rusting reinforcement, and at the joints and cracks where salt water gets in. A parkade also has its own ventilation, often its own sprinkler zone with heads exposed to vehicle strikes and to freezing, and columns that get hit by bumpers. Deterioration in a suspended slab is slow and then very expensive, and it is where a finding leads straight to a structural engineer rather than a contractor’s quote.

Service capacity

Multi unit buildings hit capacity limits that single homes never approach. On the electrical side the question is what the total service is, how it is split, whether there is any spare capacity in the house panel, and what happens the day the first tenant asks for an EV charger. That topic gets its own post on what electrical service capacity means for a building and its tenants. c4u identifies service size and panel condition and flags obvious constraints; load calculations belong to an electrician.

Water and heat are the other two. Heating capacity matters most in the north end of the valley, where January is not theoretical. The question for each is not just condition but whether the system is sized for the building as it is now, after the basement suite was added and the retail bay became a restaurant.

What the inspection cannot see with tenants in place

An honest inspection of an occupied building comes with a list of what it could not do, and the buyer should read that list as carefully as the findings. Furniture hides staining. Full closets hide the panel or the water heater. A retail stock room stacked to the ceiling hides the back wall and the floor drain. A drop ceiling hides everything above the tiles that cannot be lifted. Tenant alterations, a wall moved or a circuit added, are documented nowhere and may not be visible. Moisture behind tile and inside walls is not visible without invasive work, which an inspection does not do. And no inspection tells you whether the suite count is legal, whether the rent roll is real or whether the leases say what the vendor says they say. Those questions belong to the buyer’s lawyer and the municipality.

Tenants can be a source too. They will often tell an inspector, unprompted, about the leak in March and the heat that failed in January. c4u listens and records it as reported, not as a finding.

A scenario, plainly hypothetical

Say a buyer is under contract on a two storey main street building in Vernon: two retail bays at grade, one of them a cafe, and four apartments above, built in the 1950s. The vendor offers access to two of the four suites and says the others are “the same”. The buyer accepts. The roof is not accessed because nobody brought a ladder that reached. The cafe’s grease interceptor drains to the same lateral as the apartments.

After possession, the top floor suite nobody entered has a ceiling patched twice over a roof leak, the lateral backs up into the cafe’s floor drain in the first week of spring freshet, and the fire alarm panel in the rear corridor has had a trouble light on for months. Each of these was findable. Each was in a place the buyer agreed not to look. The price did not change, and the first year’s income went to plumbing and roofing instead of the mortgage.

Where c4u fits

c4u carries out commercial assessments of multi unit and mixed use buildings following ASTM E2018 across Vernon and the rest of the North Okanagan. Vin McConnachie does every one himself, inspects every suite that access allows, and lists plainly what was not accessed and why. The inspection ends with a walkthrough on site and a written report with photographs, notations and recommendations through the client portal, and the report names the specialist wherever one is needed. The overview of commercial property inspection in Vernon and the North Okanagan covers the full scope, and the Vernon service area page covers the base c4u works from.
