New buildings covered by Comox Valley Regional District requirements will face stronger carbon-emission standards beginning January 1, 2027, as the regional district implements Emission Level 3 of B.C.’s Zero Carbon Step Code.

The change aims to reduce greenhouse-gas emissions from new construction by moving space heating and hot-water systems away from fossil fuels and toward high-efficiency electric alternatives. It follows the regional district’s introduction of Emission Level 2 in June 2026, forming part of a phased approach intended to give the construction industry time to prepare.

The Zero Carbon Step Code forms part of the BC Building Code framework and establishes progressively stronger limits on emissions produced during a building’s operation. It complements the province’s Energy Step Code, which focuses on energy efficiency.

Emission Level 3 is described as “strong carbon performance.” It is one step below the code’s highest level, Zero Carbon Performance, and supports the provincial objective of reaching zero operational emissions from new buildings by 2030.

According to the regional district, the upcoming requirements will apply to buildings covered by Parts 3 and 9 of the BC Building Code. Builders will need to plan their designs and mechanical systems carefully, working with energy advisors to demonstrate compliance.

John Crockford, the regional district’s manager of building inspection services, says the staged rollout is intended to help builders and residents confidently make the transition while reducing community greenhouse-gas emissions.

Requirements can vary by location and building-permit date, so builders, designers and property owners planning projects should confirm which standards apply to their development. Local governments can adopt higher Energy and Zero Carbon Step Code requirements through their bylaws.

More information about the January implementation is available at Comox Valley Regional District, or through the regional district’s building department.
