The sheets in a typical permit set
Every property is different, so we confirm the exact list with your city. Most applications include:

Why these applications get sent back
These are comments plan examiners often raise. We address each one in the drawings before we submit.
From site visit to issued permit
Site visit
We measure the house, review your survey and talk through what you want to add.
Design & zoning
We confirm zoning, then design the layout and exterior with you.
Drawings & submit
Architectural, structural and HVAC sheets are completed and submitted.
Comments & permit
We answer plan-examiner comments until the permit is issued.
"Had a great experience working with them for our basement second dwelling unit project. The architectural work was done very professionally, with clear drawings, good communication, and attention to detail throughout the process."
Common questions
What if my addition does not fit zoning?
You may need a minor variance from the Committee of Adjustment. We can tell you early, and help with the application if you go ahead.
Can I add a second storey to my bungalow?
Often, yes. We check whether the existing foundation and walls can carry the new floor and what zoning allows for height.
Do I need a survey?
A property survey helps a lot for setbacks. If you do not have one, we will tell you whether your city needs it.
How do you handle structure?
We prepare structural drawings in-house and coordinate with a licensed engineer when a seal is required.
Can you design the inside too?
Yes. Our interior design team can plan finishes, kitchens and baths for the new space.
Thinking about adding space?
Send us your address and survey if you have one. We'll check what your zoning allows before you spend on design.
