Bill 44 in Vancouver: What Small-Scale Multi-Unit Housing Really Costs to Build

If you own a single-family lot in Vancouver, Burnaby, Richmond or Surrey, the maths on your property has quietly changed. Since British Columbia's Bill 44 (the Housing Statutes Amendment Act, 2023) took effect, municipalities have been required to allow small-scale multi-unit housing on lots that were once zoned for a single house. Depending on lot size and proximity to frequent transit, that can mean three, four or even six homes on one parcel.

For owners, that is an opportunity. It is also a trap. A lot that can legally hold four units does not automatically produce a profitable four-unit project. Between the zoning bylaw and the keys in your hand sit permits, servicing, soils, trades, financing and a construction market that has rarely been kind to small developers. The projects that succeed are almost always the ones that were costed properly before a single drawing was finished.

This article explains what Bill 44 changed, where small-scale multi-unit budgets go wrong in the Lower Mainland, and how independent quantity surveying services keep the numbers honest.

What Bill 44 Actually Changed

Before Bill 44, adding density to a single-family lot usually meant a rezoning application: months of staff review, a public hearing and no guarantee of approval. Bill 44 flipped the default. Local governments in BC were directed to update their zoning bylaws so that, in general, a minimum number of units is allowed as of right on residential lots.

In broad terms, the legislation sets out that:

• Lots of a certain size in larger municipalities must allow at least three or four units.
• Lots close to frequent transit service must allow up to six units.
• Municipalities cannot require a public hearing for rezonings that are consistent with an official community plan, which speeds up the process.

Vancouver has layered its own multiplex and laneway rules on top of the provincial framework, and every Lower Mainland municipality has interpreted the details differently. Setbacks, height, floor-space ratio, parking and unit-size rules vary from city to city. Always confirm the current bylaw with your municipality, because these rules have been changing quickly.

The important point for owners is this: Bill 44 removed a planning barrier. It did nothing to lower the cost of concrete, lumber, labour or borrowing. The barrier that remains is financial.

Why Small-Scale Projects Blow Their Budgets

Large developers have in-house estimators and long-standing trade relationships. A homeowner or small investor converting a family lot into a fourplex has neither. The same four problems turn up again and again.

1. The budget starts from a per-square-foot guess. A rule of thumb pulled from an online article or a friend's last project is not a cost plan. Multi-unit buildings have fire separations, acoustic assemblies, multiple mechanical systems, separate meters and parking solutions that single houses do not. A blended per-square-foot number hides all of it.

2. Site costs are discovered late. Vancouver lots can hide old fuel tanks, poor soils, high water tables, shared services, trees that need protection and lanes that do not connect cleanly. None of these show up on a zoning map. Each can add significant cost if found after the contractor is hired.

3. City fees and levies are underestimated. Development cost charges, amenity cost charges, permit fees, servicing connections and utility upgrades are real line items. The City of Vancouver has been introducing and adjusting city-wide charges, and Metro Vancouver's regional levies keep rising. Owners who budget only for construction are often surprised by a large gap in soft costs.

4. Contingency is treated as optional. On a small project, a single surprise, such as a failed inspection, a delayed utility connection or a trade that walks off the job, can eat the entire margin. Without a defined contingency, every surprise becomes a crisis.

The Cost Drivers Specific to Multi-Unit Housing in Vancouver

When we build a cost plan for a small multi-unit project, these are the categories that most often move the total.

Building code and fire separation. Once you exceed two units, the BC Building Code treats the building differently from a single-family house. Fire-rated separations between units, sprinkler requirements in some configurations, and egress rules all affect framing and finishes. Which part of the code applies depends on the size and height of the building, and the difference in cost can be material.

Energy and carbon requirements. The BC Energy Step Code, and in Vancouver the Zero Emissions Building Plan, push owners toward heat pumps, airtight envelopes, better windows and heat-recovery ventilation. These choices cost more upfront but reduce operating costs. A good cost plan prices alternatives so owners can see the trade-off rather than guessing.

Foundations, excavation and shoring. Vancouver's clay and glacial till soils, plus a high water table in many neighbourhoods, can turn a simple basement into an expensive one. Underground parking in a small project is rarely cheap.

Servicing. Older neighbourhoods may need new water, sewer and storm connections, and sometimes upgrades to the street main. Coordination with the city can add months and cost.

Finishes and unit mix. Four identical units are cheaper than four different ones. The decision between strata ownership, rental and a mix of the two also changes the specification, the financing and the exit.

Soft costs. Architectural, structural, mechanical, geotechnical and survey fees, legal and strata documentation, insurance, interest and holding costs, and marketing all belong in the budget from day one.

What a Quantity Surveyor Does for a Small Project

A quantity surveyor, often shortened to QS, is a construction cost professional. In Canada, the title Professional Quantity Surveyor (PQS) indicates formal credentials. A QS measures the work, prices it, and keeps the numbers current as the design evolves.

For a Bill 44 project, that usually breaks down into stages:

1. Feasibility cost check. Before you buy a lot or commit to a designer, a QS reviews the site, the allowable density and a concept layout and produces a high-level budget range with the key risks identified. This is often the cheapest and most valuable work in the whole project.
2. Cost plan during design. As drawings develop, the QS performs quantity takeoff, which means measuring the materials and work from the plans, and prices each element. The cost plan shows the impact of design decisions in real time, so you can choose a different cladding or a smaller unit before it becomes expensive to change.
3. Tender and procurement. The QS prepares a clear tender package, helps you select qualified bidders and compares bids on a like-for-like basis. Many owners discover that the lowest bid is the lowest because of what it leaves out.
4. Contract administration support. During construction, the QS reviews progress claims, checks them against work completed, assesses change orders and tracks the forecast final cost.
5. Close-out. Final account, holdbacks and deficiency lists are reconciled so you pay for what was built, and nothing more.

Because a QS has no stake in the build, their advice is independent. That matters when the contractor, the designer and the lender each have their own interests.

A Short Pre-Construction Checklist for Owners

Before you commit to a multi-unit project under Bill 44, answer these questions.

• Have you confirmed the current zoning, unit count and height limits with your municipality in writing?
• Has a geotechnical engineer assessed the soils and groundwater?
• Do you have a written list of city fees, levies and servicing costs?
• Is your budget built from measured quantities rather than a per-square-foot rule of thumb?
• Does it include a contingency, and do you know what it is for?
• Have you priced at least two options for the building envelope and heating system?
• Does your lender require a cost review or monitoring during construction?
• Do you know whether the project will be strata, rental or a mix, and how that affects financing?

If you cannot answer yes to most of these, you are not ready to tender the project. The time spent now will save multiples of its cost later.

The Real Value Is in the Decisions You Do Not Make

Owners often think of a cost consultant as someone who tells them what a project will cost. That is only half of it. The other half is steering design decisions early, while changes are free. A QS who sees an expensive wall assembly in a sketch can suggest an alternative that delivers the same performance for less. A QS who notices that a layout creates awkward framing or extra plumbing stacks can flag it before the structural engineer is paid to design it.

The result is a project where the budget, the design and the schedule all move together, rather than one being discovered after the others have been fixed.
