PlexIntel — the data division

The data layer under every score

The same dataset behind PlexScore™ — 205,047 scored lots, 600+ tracked Vancouver permits, build-cost models for five cities — is available to the people who need it whole: investment firms screening lots, municipalities measuring whether rezoning produces housing, and lenders checking the math before committing.

Vancouver Missing-Middle Intelligence Platform

VanPlex scores missing-middle housing potential across British Columbia. Enter any address and get its PlexScore™: the multiplex feasibility, profit, build budget, and timeline for that lot under Bill 44 and SSMUH. The score is free and takes seconds.

Behind every score is PlexRank, which has analyzed 205,047 lots across six BC cities for return on equity under current zoning. The platform also tracks 600+ Vancouver multiplex permits, zoning by district, and development costs, so the numbers reflect what is actually getting built and approved.

Homeowners use it to see what their lot can become. Investors screen lots by return on equity. Realtors pull a PlexScore™ for any listing. When an owner is ready to build, VanPlex connects them with vetted builders and experts or co-develops the project directly.

Behind the Score

The cost numbers come from someone who's built.

David Babakaiff has built homes in BC for 25+ years, most recently as principal of Alair Homes Vancouver. He co-founded VanPlex so the construction cost, timeline, and approval assumptions inside every PlexScore™ come from someone who has built these projects, not a spreadsheet. PlexRank has now scored 205,047 lots across six BC cities.

David Babakaiff interviewed on Castanet's Okanagan Edge about Kelowna's missing middle housing
In the Press

“The missing middle is still missing.”

VanPlex co-founder David Babakaiff, a Vancouver builder with more than 25 years of experience, joined Castanet's Okanagan Edge to discuss British Columbia's Bill 44 zoning in Kelowna. Drawing on VanPlex's lot-by-lot analysis, he explained that roughly 75% of the city's rezoned properties are not economical to convert to multiplex housing under current construction costs and financing.

“Zoning only establishes the legal right to build. It does not establish the economic common sense to do it.” — David Babakaiff, VanPlex co-founder and principal of Alair Homes Vancouver

Common questions

Vancouver multiplex development — answered

Can I build a multiplex on my lot in Vancouver?

Most lots in Vancouver that were zoned RS (single-family residential) before 2023 now fall under R1-1 zoning, which allows 3 to 6 units under Bill 44 and BC's Small-Scale Multi-Unit Housing (SSMUH) rules. Whether you can build 3, 4, or 6 units depends on your lot size, frontage, and the specific city. Enter your address on VanPlex for a free instant check.

How much does it cost to build a multiplex in Vancouver in 2026?

Construction costs run $450 to $550 per square foot for a standard Metro Vancouver multiplex. A typical fourplex — around 5,200 sq ft — totals $5.6M to $8M all-in, including design, permits, development cost charges (DCCs), and construction. VanPlex generates a property-specific budget when you run a PlexScore™.

What is R1-1 zoning in Vancouver?

R1-1 is Vancouver's Residential Inclusionary zone, which replaced the old RS single-family zones in 2023. Under R1-1, landowners can build up to 6 units on a standard lot — or up to 8 units if all units are rented at below-market rates. This opened roughly 71,000 Vancouver lots to missing-middle housing for the first time.

How long does a multiplex permit take in Vancouver?

A Vancouver development permit for a standard SSMUH multiplex typically takes 3 to 6 months, followed by 2 to 4 months for the building permit. Projects that match the as-of-right zoning rules move faster than those needing discretionary review. VanPlex tracks 600+ active Vancouver multiplex permits and can provide a current neighbourhood estimate.

What is PlexScore™?

PlexScore™ is VanPlex's free feasibility rating for any BC address, scored 0 to 10. It combines zoning eligibility, lot geometry, estimated build cost, projected unit prices, and return on equity into one number. A score of 7 or higher means the project is likely profitable under current market conditions. The score is free and takes about 30 seconds to generate.
