Design, permits & build — Toronto Multiplex FAQ

Getting from a lot to a finished building.

Frequently asked questions

What are the steps to build a multiplex?

Broadly: secure the lot, confirm as-of-right potential, design, obtain building permits, arrange financing, build, then lease up. As-of-right projects skip rezoning.

How long does it take to build a multiplex in Toronto?

It varies with design, permitting and construction, but small infill projects are commonly measured in months to a couple of years end to end. Your team can give a lot-specific timeline.

Do I need a committee of adjustment hearing?

Not for as-of-right unit counts. You may need minor variances for things like setbacks or height if your design exceeds the standards — your designer will flag this.

Can Lotmax help with design and construction?

Yes — Lotmax provides approved multiplex designs and the path from lot to lease-up. Start by modelling a lot on the map.

What is a massing study?

A massing study shows the buildable volume on a lot within setbacks and height limits — it tells you how big a building can fit before detailed design.
