Who it's for
One address. A different answer for each person.
The same lot means something different to a homeowner, an investor, and the agent listing it. PlexScore™ gives each of them the number they came for.

For developersVancouver 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.
