Seismic Retrofit Planning for Existing Homes
A seismic retrofit plan is an engineering package that identifies practical structural upgrades for an existing home so it can better resist earthquake forces. The plan may include anchorage, shear wall improvements, foundation connections, framing details, and construction notes.
Older single family homes were often built before current seismic expectations. Improving earthquake resistance can help reduce structural movement, protect occupants, preserve property value, and lower the risk of major repair work after an earthquake.
Municipalities may require engineered drawings before retrofit construction because structural changes affect life safety, foundations, load paths, and code compliance. A clear permit ready plan helps homeowners, contractors, and inspectors work from the same approved documentation.

Frequently Asked Questions
What is a seismic retrofit plan?
It is an engineering plan that identifies structural upgrades to help an existing home better resist earthquake forces and support permit or construction review.
Do all homes require one?
Not every home requires a seismic retrofit plan, but older homes, homes with structural changes, and projects needing permits may require engineering review.
How long does it take?
Timeline depends on home complexity, site access, available drawings, and municipal requirements. We confirm expected timing after the initial consultation.
Can you help with permits?
Yes. We prepare permit ready documentation and can support clarification requests during municipal review.
Do you provide engineering drawings?
Yes. We provide retrofit drawings and supporting engineering documentation for the agreed scope of work.
Can contractors build directly from the plans?
Contractors can use the drawings for construction once permits and project approvals are in place. We can also answer technical questions during construction.
What areas do you serve?
We serve single family homeowners throughout British Columbia, including Metro Vancouver and surrounding communities.
How do I request a quote?
