Contractor Tested: NYC Storefront Permits for Owners, Avoid Penalties


Most exterior changes to a storefront, including new storefront installation, signage over the applicable size threshold, and structural work, require a Department of Buildings permit, and landmarked buildings often need Landmarks Preservation Commission approval as well. Before signing a contract, check your address against DOB and LPC records and open the correct online application. Starting construction before that permit is issued exposes the owner to fines, violations, and stop work orders.
TL;DR:
Most exterior storefront modifications, including new installations and structural work, require permits from the Department of Buildings and, for landmarked buildings, approval from the Landmarks Preservation Commission.
Owners should verify their building’s landmark status and gather complete documentation, photos, and drawings before applying to avoid delays caused by incomplete submissions or violations.
The typical permit process involves creating an account on DOB NOW or Portico, submitting comprehensive plans with professional seals, and waiting for plan examiner approval, which can take roughly 10 days with expedited review.
Signage, security gates, and façade alterations also need specific approvals, with current rules mandating open-grille security gates meeting transparency standards and sign size regulation by zoning districts.
Working without a permit can lead to penalties, violations, or criminal charges, requiring owners to halt work immediately and undertake retroactive legalization efforts with professional assistance.

Quick step-by-step checklist owners can use today
Before calling a contractor, spend an afternoon gathering facts. A clear scope and a complete file are the two things that separate a fast approval from a stalled one.
Confirm whether your building sits in a historic district or carries individual landmark status, since that determines whether LPC review applies alongside DOB.
Define the actual scope of work: cosmetic repair, structural alteration, or full storefront replacement, because each triggers a different filing path.
Pull together photos of the current condition, dimensioned drawings if you have them, proof of ownership or authorization, and contact information for any contractor, Registered Design Professional, or engineer involved.
Decide who will act as the filer, whether that’s you, a Registered Design Professional, or a licensed contractor, and confirm that trade contractors hold the correct NYC licenses before signing anything.
Open the appropriate portal, DOB NOW: Build for standard construction filings or Portico for landmarked properties, and review the agency checklists early so your submission qualifies for expedited review where available.
Pro Tip: Run a records search on your address before you even call a contractor. An open violation you didn’t know about can knock a landmarked project out of expedited review before it starts.
How to apply for a DOB permit: DOB NOW: Build step-by-step
Nearly every storefront project outside of ordinary repair runs through DOB NOW: Build, the Department of Buildings’ online filing system. Understanding the sequence before you start prevents the back-and-forth that stalls most first-time filers.
Create or log into your DOB NOW account and start a new permit application, selecting the job type that matches your scope, such as alteration or sign installation.
Identify all required stakeholders, including the owner, the Applicant of Record, and any licensed trade contractors, since DOB NOW requires electronic signatures from each party before the filing can move forward.
Upload construction documents. Structural work, new storefront openings, or exterior alterations generally require drawings signed and sealed by a Registered Design Professional, while straightforward trade work may only need the trade contractor’s own permit filing.
For projects touching multiple systems, file each discipline separately, electrical and plumbing permits are distinct from the general construction permit, and reference the general project’s job number so DOB can link the filings together.
Submit and monitor the review queue. A plan examiner will either approve the filing or issue objections that must be answered and resubmitted before the permit is issued.
Once approved, print the permit directly from DOB NOW and post it at the job site, since inspectors will look for it on their first visit.
Objections are common on a first pass, missing dimensions, an unclear scope description, or a document that lacks a required professional seal are frequent culprits. Resubmission simply means correcting the flagged item and re-uploading, but each round can add days or weeks depending on the examiner’s queue, so a complete first submission is worth the extra hour of preparation. For a broader walkthrough of the filing basics that apply beyond storefronts, see our guide to NYC building permit requirements.
LPC and landmarked storefronts: Portico, FasTrack, XCNE, and Business Express
If your building sits within a historic district or carries individual landmark status, storefront work also needs sign-off from the Landmarks Preservation Commission, on top of any DOB permit. Check your address on the Discover NYC Landmarks map before assuming either way.
Identify your property in Portico, LPC’s online filing portal, and assemble your team, typically an owner representative and, for anything beyond minor work, an architect or design professional.
Use Portico’s Application Assistant, which asks a series of questions about your scope and routes you to the correct application type, so you know exactly which drawings and photos to prepare before you start uploading.
Upload clear photos of existing conditions alongside dimensioned drawings of the proposed work, then submit through the portal for LPC staff review.
Check whether your project qualifies for FasTrack or an Expedited Certificate of No Effect, both of which move faster than standard review but only when the application is complete and the property has no outstanding LPC violations.
Commercial storefront owners can also route certain filings through Business Express, a service built to help small businesses move filings through city agencies with less friction.
Pro Tip: A single missing photo or an undimensioned drawing is enough to bump a project out of FasTrack and into the standard queue, so double-check your upload against the Portico checklist before you hit submit.
Which storefront jobs require permits and which are exempt
NYC Administrative Code §28-105.4 lays out categories of work, ordinary repairs, emergency work, and certain minor alterations, that don’t require a DOB permit. In practice, the exemption is narrower than most owners expect.
Ordinary repairs, such as patching plaster, repainting, or replacing worn hardware without altering structural elements, generally do not require a permit.
Emergency work needed to protect life or property can begin immediately, but it must be reported through an Emergency Work Notification, and formal filings follow after the fact.
New storefront installations, including replacing a full storefront system, do require a permit and typically need construction documents.
Structural work such as lintel replacement, curtain wall installation, or removing a load-bearing element always requires a permit and sealed drawings from a Registered Design Professional.
Awning installation, exterior alterations that change the building’s facade, and any work touching egress or fire separation also fall under permit requirements.
Electrical, plumbing, and gas work each carry their own trade-specific permit obligations, and only a licensed electrician, plumber, or fitter can pull those permits.
The line between “ordinary repair” and “alteration” is where most disputes with DOB examiners happen. A cracked storefront pane replaced like-for-like is a repair. The same pane replaced with a different glazing system, a new frame, or a larger opening becomes an alteration that needs review. When in doubt, treat the work as requiring a permit and confirm with DOB before starting, since retroactive fixes cost more than the delay of asking first. For more detail on when a Registered Design Professional must be involved, see our alteration permits guide for New York and New Jersey.
Signage and security gate rules that affect storefront permits
Storefront signage and security gates carry their own layer of rules, separate from the general construction permit, and they trip up more projects than owners expect.
Sign size is governed by zoning district rules, and signs above the applicable threshold require DOB sign permit review or a zoning confirmation before installation.
New illuminated or projecting signs often need a separate sign permit filed through DOB, and the Sign Enforcement Unit monitors compliance after installation.
Landmarked properties add another layer: LPC must approve sign design, size, and placement, so coordinate that review alongside your zoning check.
Security gates installed since 2011 must be open-grille rather than solid panel, and newly installed gates must provide at least 70% transparency, a rule intended to keep storefronts visible for both retail display and street safety.
Coordinate gate and signage work across agencies early. DOB handles the construction permit, the Department of City Planning’s zoning rules set the size limits, and LPC weighs in if your building is landmarked.
Owners replacing an old solid gate often assume a like-for-like swap is fine. It isn’t, current policy requires the new gate to meet the open-grille standard regardless of what it’s replacing. Businesses sourcing compliant gate systems can look at open-grille options from vendors like Modern Fence, which fabricates gates built to meet transparency requirements, or review commercial door and gate installation options through 911 Garage Door Repair Pros.
Who to hire, who pulls which permits, and how inspections are arranged
Storefront projects involve several distinct roles, and confusing them is one of the fastest ways to stall a filing.
The Applicant of Record, typically a Registered Design Professional for anything beyond simple repairs, prepares and submits the construction documents and takes responsibility for code compliance on the filing.
Licensed trade contractors, electricians, plumbers, and sign hangers among them, pull their own permits for their specific scope; a general contractor cannot file an electrical permit on a licensed electrician’s behalf.
The owner, not the contractor, must engage the Special Inspection Agency directly when the project documents call for special inspections, a structural requirement meant to keep the inspecting agency independent from the crew doing the work.
Good contractor coordination means requesting copies of every filed document, signed inspection reports, and the final sign-off paperwork, so you have a complete record if a future buyer, lender, or inspector asks for it.
Pro Tip: Ask your contractor for copies of every permit application and inspection report as they’re filed, not at the end of the project. Reconstructing that paper trail after the fact is far harder than requesting it as you go.
Timelines, fees, and cost drivers for storefront permits and reviews
Review times swing widely depending on completeness. A DOB filing with sealed drawings, correct stakeholder signatures, and no open violations moves through plan review far faster than one missing any of those pieces. LPC’s expedited paths give the clearest benchmarks available: FasTrack targets roughly 10 days and Expedited Certificate of No Effect targets roughly 3 days, but both depend on a complete application and a clean violation history.
DOB filing and permit fees vary by job type and scope, and plan examination charges apply on top of the base permit fee.
LPC charges its own application fee separate from any DOB fee, and trade contractors pay separate fees for their own permits.
Professional fees for a Registered Design Professional’s drawings and a Special Inspection Agency’s services add to the total, particularly on structural or curtain wall work.
Outstanding DOB or LPC violations on the property will delay or block a new filing until they’re resolved, adding both time and legal cost.
Energy code analyses, required on certain exterior envelope changes, add another review step and another professional fee if your project touches insulation, glazing, or the building envelope.
The single most effective way to control both cost and timeline is a complete first submission. A pre-application consultation with DOB or a careful pass through the Portico checklist before filing catches the gaps that would otherwise surface as objections weeks later.
Common pitfalls and how to avoid delays or denials
Most storefront permit delays trace back to a small handful of avoidable mistakes.
Filing with an existing DOB or LPC violation still open, which blocks expedited review and can stall the entire application until resolved.
Submitting incomplete drawings or photos, missing a dimension, an elevation, or a required detail is enough to drop a landmarked project out of FasTrack.
Hiring a contractor without the correct trade license for the scope, which means the permit for that portion of the work can’t be issued at all.
Overlooking energy code requirements on envelope work or skipping the special inspection review needed for structural elements, both of which surface as objections late in the process.
Run a violations search and a document completeness check before you file, not after an objection comes back. That single habit prevents the majority of the delays owners run into.
If you already did work without a permit: penalties and the path to legalization
Work performed without a permit, commonly called WOP, exposes owners to real consequences. DOB can issue civil penalties, formal violations that attach to the property record, and in serious cases, criminal exposure with a required court appearance.
Stop all further work immediately and document current conditions with photos before anything changes.
Hire a Registered Design Professional and a licensed contractor experienced with legalization filings to assess what was built against what code requires.
File corrective applications through DOB NOW and, if the property is landmarked, through Portico, to bring the work into the review process retroactively.
Resolve any fines or violations tied to the WOP finding, which may include negotiated settlement terms depending on the scope and severity.
Depending on the assessment, the path forward is either a post-facto permit with remedial drawings, or in some cases, partial demolition and restoration to bring the storefront back into compliance.
Legalization timelines run longer than a standard permit because the RDP has to reverse-engineer what was actually built before filing corrective drawings. A contractor with direct experience resolving DOB violations can shorten that process by knowing which documentation DOB examiners expect to see first.
Practitioner perspective: contractor workflows and real-world expectations

On every storefront intake, we start with a site survey and a violations search before discussing scope, because a clean starting point changes the entire timeline. Breaking the project into discrete pieces, structural, cosmetic, signage, and trade work, makes it clear early which pieces need a Registered Design Professional’s seal and which don’t.
Coordination between the contractor, the RDP, and the Special Inspection Agency matters more than owners usually expect. When those three parties communicate before filing rather than after an objection, inspections get scheduled around the actual construction sequence instead of causing gaps where crews wait on paperwork. A straightforward storefront replacement with no structural change tends to move through DOB review in a matter of weeks once the application is complete. A landmarked property with a curtain wall change or a lintel repair takes longer, since it layers LPC review, structural design, and special inspection scheduling on top of the base DOB process. Owners who stay reachable for quick document requests during plan review consistently see faster outcomes than owners who go quiet after signing the contract.

FAQ
Do you need a permit to replace drywall in NYC?
Ordinary drywall repair or replacement that doesn’t touch structural elements, electrical, or fire-rated assemblies typically falls under the ordinary repair exemption and doesn’t require a DOB permit. If the drywall work is part of a larger alteration, such as removing a wall or changing a fire-rated partition, the full project generally needs a permit even though the drywall itself would not on its own.
Is there a building height limit in NYC?
Building height limits in New York City are set by zoning district rather than a single citywide number, and they vary block by block based on the applicable zoning designation. A storefront project rarely affects overall building height, but any work near the roofline or affecting the building envelope should be checked against the property’s specific zoning district before filing.
What requires a permit on a storefront project?
New storefront installation, structural changes like lintel or curtain wall work, exterior alterations, and signage above the applicable size threshold all require a DOB permit, and landmarked buildings need LPC approval as well. Ordinary repairs that don’t touch structure or systems are generally exempt under Administrative Code §28-105.4.
How long does a storefront permit take to get in NYC?
Timelines depend heavily on completeness. LPC’s expedited FasTrack review targets roughly 10 days and its Expedited Certificate of No Effect targets roughly 3 days, both only for complete applications with no outstanding violations, while standard DOB review runs longer and depends on the plan examiner’s current queue.
What happens if you build a storefront without a permit in NYC?
Performing storefront work without a permit exposes the owner to civil penalties and formal violations, and in serious cases criminal exposure with a court appearance. Resolving it requires stopping work, hiring a Registered Design Professional to prepare corrective documents, and filing a legalization application through DOB or LPC depending on the property.
