Underlying permit/job matters
The AHV is tied to authorized construction activity.
NYC After Hours Variance (AHV) for Construction Work
Construction outside normal NYC hours generally requires an After Hours Variance. The filing has to match the underlying job and should be planned before the intended work date.
What This Service Covers
DOB requires AHVs for construction before 7:00 AM, after 6:00 PM, or on Saturday/Sunday and says applications should be filed at least two business days before the first intended work day.
Noise rules still apply
DEP construction-noise requirements and mitigation planning may also apply.
Late planning causes delays
AHVs have advance submission deadlines and renewal rules.
Have an active property issue?
Send the property address, notice/violation/permit information and any available photos or agency documents. We will identify the immediate deadline and scope the next paid phase before detailed technical work begins.
