Demolition & Change of Use
Full and partial demolition permits, and filings to change how a building is used.
Demolition and change of use look unrelated but share a trait: both alter what a property legally is, so both draw scrutiny beyond the physical work. Partial demolition adds a structural question — what holds up what remains.
Scope
- Full and partial demolition permits
- Structural review and shoring design for partial demolition
- Utility disconnect coordination
- Change of use and occupancy classification filings
- Code analysis for the proposed new use
- Parking, egress and accessibility review under the new use
- Certificate of Occupancy update following the change

Common questions
Do I need a permit to take down an interior wall?
If it is load bearing, yes — and determining that is a structural question, not a visual one.
I am leasing a space that was a store and want a café. What is involved?
That is a change of use. It brings occupancy classification, egress, accessibility and often health department review. Worth checking before the lease is signed.
