Foundations must comply with OBC Part 9 standards.

Before breaking ground on your new home, it’s critical to determine whether your chosen lot is zoned for a prefab or modular construction.
The City of Guelph enforces zoning bylaws that dictate how land can be used, and these apply directly to prefab homes Guelph.
Most residential zones allow for prefab dwellings, but there are nuances.
For example:
Tiny homes or accessory dwelling units (ADUs) may be subject to different rules than larger, single-family structures.
There may be restrictions on lot setbacks, building height, parking requirements, and maximum SQ. FT limits.
Locations like Mini Lakes or suburban pockets may have specific zoning overlays that impact your design or placement.
Working with an experienced team like ours ensures these zoning guidelines are reviewed early in the process.
Inevitably, this will help you avoid delays or unexpected costs.

Fire safety: Proper fire-rated walls, smoke detectors, and egress points are non-negotiables.
