Bill 44 and Prefab: More Homes on One Family Lot

Two things have changed at once for BC families. The rules now let many single-family lots hold several homes, and prefab building makes putting up those homes faster. Together they give families a real path to build a multiplex for the whole family. This guide explains how the two fit together.

What Bill 44 does

Bill 44 is BC's small-scale housing legislation. It requires many municipalities to allow three to six homes on lots that used to permit only a single house (Source: Government of BC, small-scale multi-unit housing legislation). Lots near frequent transit can allow more, and cities like Vancouver go further with their own policies.

For families, the practical effect is simple: a lot that once held one house can now hold a duplex, triplex, or fourplex. That is a big shift, and it is the foundation of the whole multiplex movement in BC. We cover the buyer side of this in our guide to multi-generational living.

Why prefab fits Bill 44 so well

Bill 44 opened the door, but you still have to build the homes. That is where prefab helps. Building a multiplex the traditional way takes many months on site. Prefab moves much of the work into a factory that runs while your lot is prepared, so the building stage is faster and more predictable, with fewer weather delays.

For a family turning one lot into three or four homes, that speed matters. It shortens the disruption, lowers financing costs, and gets everyone moved in sooner. See prefab vs traditional for the full comparison.

What this means for your family

If your family owns a lot, or plans to buy one, Bill 44 plus prefab gives you options that did not exist a few years ago:

• Parents and grown children can each have their own home on one lot.
• You can share the land cost, the biggest cost in Greater Vancouver, across several homes.
• You can build faster than a traditional multiplex, with a clearer schedule.
• You can live in some homes and rent others for income.

How to find out what your lot allows

The number of homes depends on your lot's size, location, and your municipality's zoning. A builder or the city checks your specific lot early, so you know your options before you commit. Our prefab fourplex on a standard lot page shows what a typical Vancouver lot can support.

What this comes down to

• Bill 44 lets many single-family lots in BC hold three to six homes.
• Prefab makes building those homes faster and more predictable.
• Together they give families a practical way to build a multiplex on one lot.
• The number of homes depends on your lot, which a builder confirms early.

Frequently asked questions

What is Bill 44 in BC?

Bill 44 is provincial legislation that requires many municipalities to allow three to six homes on lots that used to permit only a single house, with more allowed near frequent transit.

How many homes can I build under Bill 44?

Commonly three to six, depending on your lot's size and location and your city's zoning. Vancouver allows more on suitable lots. A builder confirms the number for your lot.

Do I need to rezone to build a multiplex?

Often not, because the provincial rules make multiplexes a permitted use on many lots. Your municipality's zoning sets the details, which a builder or the city can confirm.

Why does prefab pair well with Bill 44?

Bill 44 lets you build more homes, and prefab builds them faster by moving work into a factory. Together they make turning one lot into several homes practical and quicker.

Can my family build on a lot we already own?

Yes, if the lot qualifies under the rules. Many families build on a lot they own or buy one to build on. A builder checks what your specific lot allows.

Does Bill 44 apply everywhere in BC?

It applies to many municipalities, with details varying by city. Larger municipalities have updated their zoning. Check your city's current rules or ask a builder.

How many families can live on one lot?

As many as the number of homes allows, commonly two to six households. Each home is private, so families keep their independence while sharing the lot.

Is prefab required to build a Bill 44 multiplex?

No. You can build traditionally or with prefab. Prefab simply tends to be faster and more predictable. See prefab vs traditional.
