About

We read the rules so you don’t have to.

Built in Waterloo, Ontario, for homeowners and the contractors and designers they hire. We turn the space you’re picturing into the drawings and City forms you need to build it.

What it is

Software that designs small residential projects (decks, fences, bathrooms and basements) to the Ontario Building Code, draws the permit drawings, fills in the City’s forms and tells you exactly what’s left before you submit.

What it isn’t

A permit office, an engineering firm or a guarantee. You, or your designer, submit the application. The City decides.

Where it works

The Building Code checks work anywhere in Ontario. Local permit rules, fees and forms are checked municipality by municipality (285 so far), and the application is filled in for each. See the permit rules by city
