Estimate total DOB permit and professional costs by project type.
A planning range, not a quote — actual cost depends on scope, square footage, special inspections, and whether BSA variances, Landmarks review, or FDNY/DEP/DOT permits apply. DOB filing fees themselves are modest; professional fees drive the total.
DOB filing fees depend on the job type and scope:
The largest cost component is often professional fees:
Budget for these commonly overlooked items: DOB plan examination re-review fees, post-approval amendment fees, BSA applications for variances ($5,000-$20,000), Landmarks Preservation Commission filings for historic districts, DEP sewer connection approvals, DOT highway permit fees for sidewalk work, and FDNY plan review fees for fire protection systems.
Total costs range from $3,000-$8,000 for a simple renovation to $50,000+ for new construction. DOB fees are relatively small; the majority of cost is professional fees (architect, engineer, expeditor) and required inspections.
Most NYC permits require a licensed architect (RA) or professional engineer (PE) to prepare and file. Homeowners can file for certain minor work in owner-occupied 1-2 family homes, but this is limited to specific work types.
This is an estimate. Look up any NYC address for the actual assessed value, tax class, zoning, and FAR — free, no account needed.
