London, Ontario Renovation Energy Code & Bylaw Guide
London, Ontario property owners and contractors must meet energy conservation requirements when renovating buildings. This guide explains when energy rules apply, the roles of City of London Building Services and provincial regulation, typical compliance steps, and what to expect from inspections and enforcement. It is focused on municipal procedures and official sources for London, Ontario to help you plan compliant renovations and avoid enforcement actions.
Overview of energy requirements
Renovations that alter building envelope, heating, ventilation, air conditioning, or major systems commonly trigger energy conservation requirements under the provincial building framework and city permitting process. The City of London processes building permits and requires submitted work to meet applicable energy and building code rules; see the City of London building and renovating permits page for permit triggers and submission guidance City of London Building Permits[1].
- Major envelope changes (windows, insulation, exterior cladding) often require energy compliance documentation.
- HVAC replacement or fuel-switching work may trigger additional efficiency or ventilation requirements.
- Alterations that change conditioned floor area or use can require updated compliance reports or calculations.
When renovations trigger energy code obligations
Not all small repairs trigger energy code compliance, but many renovations do. Typical triggers include changes to building envelope components, replacement of heating systems, additions of conditioned space, and significant interior alterations. Documentation expectations vary by project scope and the City of London permit review process.
- Submit permit applications before work starts to avoid stop-work orders.
- Provide fee estimates or schedule payments as required by the permit process.
- Provide energy compliance reports, calculations, or performance assessments when requested.
