Delta is drafting a houseplex zone. Here is what applies until it lands.

Delta is a useful case study in how differently one piece of provincial legislation can land, and in why a landowner has to separate what is in force from what is being discussed.

What applies today

Delta permits small-scale housing on properties already zoned to allow a single detached or duplex dwelling, naming RS and RD zones as examples along with some CD zones. No rezoning is required on those properties.

Unit maximums run on lot size, with one geographic exception.

• Up to 280 square metres: a maximum of three units.
• Over 280 square metres: a maximum of four units.
• Over 280 square metres and within 400 metres of frequent transit along Scott Road: a maximum of six units.

Delta adopted these regulations on June 24 2024, ahead of the provincial deadline.

The Scott Road corridor

The third bullet is what makes Delta distinctive, and it is unusually specific for a zoning provision.

The six-unit case is not tied to frequent transit generally. It is tied to frequent transit along Scott Road. A named corridor, in a municipality that stretches from North Delta through Ladner to Tsawwassen.

In Delta, the difference between four units and six is not how good your transit is. It is whether you are on one particular road.

The same corridor carries a parking consequence. Delta requires one parking space per unit on the lot, exempting dwelling units under 33 square metres and any dwelling units on properties within 400 metres of frequent transit along Scott Road. So a Scott Road property gets both the higher unit ceiling and relief from parking, while the rest of Delta gets neither.

Delta's own 2026 material is explicit that this is stable, stating that parking requirements are not changing and one on-site space will continue to be required for each unit on the lot. That is a helpful thing for a municipality to say plainly, since it removes a question a landowner would otherwise have to ask.

For how narrow the frequent transit provision is across the region generally, see the six-unit transit rule.

The 33 square metre exemption

The small-unit parking exemption is worth pulling out because it is a design lever rather than a geographic accident.

A dwelling unit under 33 square metres carries no parking requirement anywhere in Delta. That is a small unit, and it will not suit every project or every market. But on a constrained lot where parking is the binding limit on unit count, it is a genuine option to evaluate rather than dismiss.

It is the same category of decision as Pitt Meadows scaling parking by unit size, covered in Pitt Meadows R-3, R-4 and R-6. Two municipalities, both making unit size a lever on the parking obligation, through different mechanisms.

The zone that does not exist yet

Now the part that requires discipline, because it is easy to plan around something that has not happened.

Delta implemented small-scale housing by amending its existing single-family zones, which is the patch approach several municipalities took. Staff reported to Council on April 27 2026, following consultation in November 2025, that they will continue monitoring how the current regulations work in practice and plan to explore a standalone houseplex zone for future Council consideration.

Read that wording carefully. Plan to explore. Future Council consideration. That is a proposal at an early stage, with no adoption date attached.

What is on the table

The changes being considered alongside the new zone are worth knowing, if only so you recognize them when they surface.

• Adding houseplexes as a permitted use.
• Increasing the maximum height for sloped roofs from 9.5 to 10.5 metres.
• Removing floor space ratio.
• Consolidating and standardizing zones.
• Increasing the minimum frontage for new lots from 11 to 15 metres, while maintaining a 30 metre depth.

Most of those would loosen constraints. The last one would tighten a requirement, and it applies to new lots rather than to development on existing ones. Anyone assuming a future zone would be uniformly more permissive should notice that.

Removing floor space ratio is the change with the largest potential effect on what fits, since floor space ratio is often the binding constraint before setbacks are. Whether it happens is Council's decision.

How Delta defines a houseplex

Delta's definition contains a constraint people miss: a building with three or four main dwelling units on one lot, each with its own exterior entrance, and secondary suites are not permitted in a houseplex.

That last clause matters for anyone planning a mix, such as four principal units with suites in some of them. Delta's definition rules that out. Surrey takes the same position on its houseplexes, as covered in strata vs freehold multiplex ownership in Surrey, so it is a pattern in the municipalities using houseplex terminology rather than a Delta quirk.

Designing now or waiting

Landowners ask whether to wait for the new zone. Our answer is that a proposal at the exploration stage is not a timeline.

There is no adoption date, the content could change through consultation and Council review, and one proposed change tightens rather than loosens. Holding land on the expectation of a zone that has not been drafted carries real cost in a market that moves.

What is reasonable is to confirm the current status with Delta at the point of decision, since this file is active and the position may have moved since anything was written about it, including this. Our Delta area page tracks where things stand.
