My strata in Coquitlam says I need approval before modifying my deck stairs — what do they typically want to see?

Strata corporations typically require an alteration agreement, architectural drawings showing the proposed changes, and confirmation that the work meets BC Building Code requirements before approving deck stair modifications.

Most strata bylaws classify deck stairs as part of the building envelope or common property infrastructure, even when they serve an individual unit. This means any modification — whether replacing existing stairs, changing the design, or adding new stairs — requires formal strata approval through an alteration agreement process.

What Your Strata Will Likely Request:

Your strata council will typically want to see detailed drawings showing the current stairs versus the proposed design, including dimensions, materials, railing specifications, and how the stairs connect to both the deck and the ground or landing below. They need to verify that the new stairs won't interfere with building maintenance, emergency access, or neighbouring units. Many strata corporations also require confirmation that the work will be performed by a licensed contractor with valid WorkSafeBC coverage and liability insurance.

Building Code Compliance Documentation:

Since stair modifications often trigger BC Building Code requirements, your strata may request confirmation that the new stairs meet current code standards for rise/run ratios (maximum 8-inch rise, minimum 10-inch run), handrail height (34-38 inches), guardrail requirements if the stairs are elevated, and proper structural connections. If your stairs are more than 600mm above grade at any point, a building permit from the City of Coquitlam will likely be required, and your strata will want to see that permit approval.

Timeline and Process Considerations:

Submit your alteration request well before you plan to start construction — most strata councils meet monthly, and the approval process can take 30-60 days. Include material specifications (cedar, composite, pressure-treated), colour samples if appearance standards apply, and a construction timeline. Some strata corporations have specific requirements about construction hours, contractor parking, and site cleanup that must be addressed in your application.

Potential Sticking Points:

Strata councils often scrutinize stair modifications that change the visual appearance of the building, affect drainage patterns, or require excavation near the foundation. If your stairs currently drain onto common property and the new design changes that drainage, expect additional review. Similarly, if the new stairs extend further into common property areas or affect snow removal access, the council may require modifications to your proposal.
