Sarah's Expert Insight
OBC Compliance Specialist
"The 2024 updates to Section 1.11 are a game-changer for modular tiny homes in London, Oakville, and Muskoka, as they allow for greater flexibility in where these units are manufactured versus where they are installed. At empcontracting.ca Inc. your construction contractor in London, Ontario, we remind clients that the 'declaration of assumptions' is the most vital document for unknown sites to ensure the structure can handle the specific snow loads of Muskoka or the seismic requirements of the GTA."
The 2024 Building Code Compendium introduces critical updates for the modular and tiny house market.

Section 1.11: Defining Tiny House Scope and Size
According to the OBC, these regulations specifically apply to houses that contain only one dwelling unit and possess a building area of 37 m² or less. This section is designed to facilitate the movement of structures that are partially constructed in one municipality and moved to another for final installation.
OBC 1.11.1.1. Scope of Off-Site Houses
The code covers two primary scenarios for tiny houses:
- Structures moved between known municipalities before occupancy.
- Structures built at a location where the final destination is not yet determined.
Navigating Building Permits for Tiny Homes
Obtaining a permit for a tiny house under the Building Code Act involves specific exemptions related to site installation, provided certain conditions are met. empcontracting.ca Inc. your construction contractor in London, Ontario can assist in managing the dual-layered permit process required for these unique builds.
Location-Dependent Requirements
Even for off-site builds, the OBC mandates that construction must account for the specific characteristics of the final site. If the site is unknown, the applicant must file a declaration of assumptions. These 'location-dependent requirements' include:
- Climatic and Seismic Loads: Structural integrity based on regional snow loads and earthquake risks.
- Temperature-Based Requirements: Insulation and HVAC standards suitable for the local climate.
- Limiting Distance and Fire Safety: Ensuring the building face meets safety standards relative to property lines.
- Soil Gas Control: Essential radon and soil gas mitigation strategies.
