FAQ
Do you only work in NYC?
No. While most projects are in New York City, we also file applications and resolve violations in other New York State counties.
Can you help if work was done without a permit?
Often yes. We map a corrective path, coordinate inspections, and file for sign-off; penalty mitigation may apply in specific cases.
What’s faster—LNO or C of O?
When records support existing use, an Letter of No Objection ( LNO) can be faster. If use/egress/occupancy changed, you’ll likely need ALT-1/ALT-CO with a C of O.
Do you work with architects/engineers?
Yes. We frequently coordinate with A/E teams on drawings, energy, asbestos, and special inspections.
How do you quote?
After a brief scope/records review, we price by milestones (filing, inspections, close-out) so expectations stay aligned.
