A lot that was worth one house is now worth three, four, sometimes six. That changed what is worth buying. It did not change how long it takes to clear what is already standing on it.
Since the Province required municipalities to allow small-scale multi-unit housing on single-family and duplex lots, Surrey has rezoned on a scale that is easy to underestimate — the City's own draft materials described the change as applying to more than seventy thousand lots. Council approved a comprehensive review of the SSMUH regulations and their implementation in July 2026, so the details continue to move. Confirm what applies to a specific lot using the City's SSMUH zoning lookup tool before you rely on anything.
The development side of this has been covered to death. The part nobody writes about is what sits on those lots right now.
The houses are old, and that is the whole point
The lots that became worth redeveloping are, overwhelmingly, older single-family neighbourhoods. The housing stock on them is the housing stock of the 1960s through the 1980s.
That matters because asbestos was used across ordinary residential building products through that entire period — floor tile and the mastic beneath it, sheet flooring, drywall joint compound, textured ceilings, pipe and duct insulation, cement board, roofing. On a house of that vintage, a hazardous materials survey finding something is the expected result, not the unlucky one.
So the practical reality of an SSMUH teardown is this: the survey is not a box to tick near the end. It is the first real step, and it carries the longest lead time of anything on your schedule.
A developer who has done rezonings but never a teardown often sequences this like a planning process — secure the lot, finalise the design, then deal with the existing structure. By the time the survey is ordered, the construction schedule is already committed, and a positive result lands as a delay rather than a known cost.
Multiple lots multiply the problem, not the cost
SSMUH has pushed a lot of small developers from one project at a time to several. That changes the shape of the work in a way worth planning for.
Surveys, abatement crews, and clearance consultants all have finite availability. Four teardowns sequenced one after another take four times as long as one. Four teardowns scoped together, with the surveys booked as a block and the abatement scheduled as a continuous run, take considerably less — and usually price better, because mobilisation is being spread rather than repeated.
The inverse is also true, and more painful. If you buy four lots and discover the hazmat position on all four at the same late moment, you have four stalled schedules at once and no sequencing room to absorb it.
What to do during due diligence
- Arrange the survey before closing where you can. With the seller's cooperation this is often possible, and it moves weeks off the front of your schedule.
- Treat findings as a number, not a surprise. What turns up affects budget and timeline and belongs in your offer or your conditions, the same as a structural issue would.
- Book utility disconnections in parallel the day you close. Gas, electrical, and water are scheduled by separate organizations on their own calendars, and sequencing them one after another is the most common self-inflicted delay.
- Confirm the zoning position on the specific lot. Permitted unit counts vary with lot size and proximity to transit, and the framework has been under review — do not assume one lot's answer applies to the next.
Where Nexora fits
Nexora coordinates and manages the clearing stage of these projects. We engage and manage the qualified consultants who carry out hazardous materials surveys, the licensed contractors who perform any abatement the survey triggers, and the independent clearance that lets the next trade start — across one lot or a run of them.
For developers running several SSMUH sites at once, the useful part is usually the scheduling: one party holding the sequence across all of them, rather than each site discovering its own problems on its own timeline.
