Common questions

These answers are meant to be practical and useful for homeowners considering an addition, extension, or garage project.

Do additions always require permits?

Most structural addition work will require drawings, approvals, and inspections. Permit coordination is usually part of the process.

Can you help evaluate options before final scope is locked?

Yes. We can help think through the best path before construction starts, including practical scope and layout discussions.

Can garage work be part of a larger renovation plan?

Yes. Garage-related work can often be part of a broader property improvement plan depending on the goals of the project.
