Start Here: Is HDLC the Right Authority for Your Property?

Don’t assume that every property described as “historic” follows the same process. New Orleans has local historic districts, individual landmarks, the Vieux Carré, National Register districts, and areas with different levels of HDLC control. The safest first move is to verify the address against the City’s current historic-district and landmark resources before you plan the project around assumptions about approval.

Use the City’s Historic Landmarks & Districts map to confirm the property’s local designation and then follow the applicable review path.

Use this as a routing tool, not a substitute for checking the actual address and current City rules.

If the Property Is in the French Quarter, Start With the Vieux Carré Commission

The French Quarter is the biggest jurisdiction trap in an HDLC search. The City states that the Vieux Carré Commission (VCC) has jurisdiction over private and semi-private properties within the Vieux Carré Historic District. Exterior work there begins through the City’s One Stop process and requires VCC approval before work starts.

For a French Quarter property, go directly to the Vieux Carré Commission rather than trying to force the project into an HDLC workflow.

Full-Control and Partial-Control Districts Do Not Have the Same Review Scope

A local historic-district label alone doesn’t tell you how much authority HDLC has over a specific project. The City’s current demolition-review guidance identifies four partial-control districts where HDLC jurisdiction is limited to work that meets the HDLC demolition definition.

Control levels and district boundaries can change. Recheck the current City district information for the property before work is designed or contracted.

What HDLC Approval Means: Certificate of Appropriateness vs. Building Permit

Owners often search for an “HDLC permit,” but the City uses two different approvals. HDLC issues a Certificate of Appropriateness for regulated historic-district work. The Department of Safety & Permits handles building permits and code review. A project may involve both.

Some work that does not need a Safety & Permits building permit can still require HDLC approval. One approval should never be treated as proof that the other is unnecessary.

What Exterior Work Commonly Needs HDLC Review?

The City’s current CofA page covers a broad range of exterior work in local historic districts and on nominated/designated landmarks. Common categories include repairs, alterations, additions, demolition, relocation, new construction, fencing, paving, and other site work. That is a starting point, not a complete exemption or approval chart for every property.

• Repairs or replacement of exterior materials and features
• Changes to windows, doors, siding, roofing, porches, steps, railings or other visible exterior components
• Additions or new construction
• Demolition, partial demolition or relocation
• Fences, paving and other site work that falls within the current rules

Include Repair-in-Kind and Small Exterior Changes in the Project Scope

One of the most practical instructions on the City’s application page is also one of the easiest to miss: itemize everything you plan to do on the exterior, even work that is simply repairing what is already there. For each item, identify where it is, what exists now, and what material or product is proposed. A complete scope gives staff something concrete to review and reduces the chance that a “small” omitted item becomes a problem later.

Does Your Project Qualify for the HDLC Express Lane?

The HDLC Express Lane is the current expedited route for eligible work that meets the Design Guidelines and arrives as a complete application. The City states that qualifying CofAs can be issued within approximately 1–3 business days. That’s an HDLC estimate for eligible complete applications—not a guarantee for every project and not the timeline for a separate building permit.

Examples on the current City list include roof replacement, repairs or replacement work that matches existing conditions, solar and battery installations, HVAC, gutters and downspouts, signage and lighting, security features, ADA ramps and lifts, generators, handrails, awnings, shutters, roof vents, fencing, paving and shoring.

• □The proposed work appears on the current Express Lane eligibility list or HDLC staff confirms it can use that route.
• □The work meets the current HDLC Design Guidelines.
• □The One Stop application is complete.
• □All requested supporting documents have been uploaded.
• □The property does not have a disqualifying existing violation under the current Express Lane criteria.
• □Any separate building-permit requirement has also been identified.

If the scope isn’t clearly listed, check the current HDLC Express Lane page or contact HDLC rather than assuming the project qualifies.

Staff Review, ARC, or Full Commission: How the Review Path Changes

The biggest timing difference is often not the size of the project; it’s the review route. The City can approve some work at staff level, refer other work to the Architectural Review Committee (ARC), and send certain matters to the full Commission. The City’s CofA page notes that projects involving demolition, new construction, or retention of work completed in violation are among those that may require full Commission review.

These are HDLC review estimates, not combined HDLC + building-permit timelines.

A Major Renovation Can Trigger Demolition Review

A project can be called a renovation in everyday language and still meet HDLC’s demolition definition. The current City rule looks at specific structural and material thresholds over a five-year period. Use the thresholds as an early signal to talk with HDLC—not as a way to self-certify a real project.

The City applies these criteria within a five-year period. For a real project, ask HDLC to determine whether the proposed scope triggers demolition review.

How to Apply for HDLC Approval in New Orleans

Treat the application as a sequence rather than a form-filling exercise. The goal is to give the City a complete, consistent picture of the property, the existing condition, and the proposed exterior work.

1. Verify the property’s historic-review jurisdiction and status using the City’s current maps and district information.
2. Review the HDLC Design Guidelines that apply to the proposed work.
3. Define and itemize the complete exterior scope, including repair-in-kind.
4. Gather clear existing-condition photos and supporting documentation.
5. Prepare drawings, site or roof plans, specifications, and material details where the scope requires them.
6. Start the applicable building-permit application through the City’s One Stop portal so the HDLC CofA review can begin.
7. Respond promptly if staff requests clarification or additional documents.
8. Follow the staff, ARC, or Commission route assigned to the project.
9. Obtain the CofA and any separate required permits before beginning regulated work.
10. If the exterior scope changes materially in the field, ask the applicable City office whether the approval needs to be revised before proceeding.

What to Include in the Scope of Work

A useful scope is specific enough that a reviewer doesn’t have to guess what will be removed, repaired, covered, replaced, or added. Identify the location of each item, the existing material, the proposed material if it is changing, and any relevant dimensions, quantities, colors or product information.

Documents That Can Help Prevent an Incomplete Application

Not every project needs every document, but the City’s current application and Express Lane pages list the following materials as common requirements or supporting items, depending on the scope:

• □A detailed, itemized scope of work
• □Clear photos of the work locations and deteriorated items being replaced
• □Signed contract when required by the applicable application route
• □Measured drawings when needed
• □Site plans or roof plans showing relevant equipment or work areas when needed
• □Product or material specification sheets when needed
• □Replacement-material information and the exact location where it will be used

Safety & Permits can require additional information for the building permit, so don’t treat the HDLC document list as a complete building-permit checklist.

If you’re coordinating a broader renovation or ongoing building operations, you can review LaNasa’s historic property management services once you understand the approval path.

How Long Does HDLC Approval Take?

There’s no single answer that holds for every project. The current City pages publish short estimates for two staff-driven routes, while ARC and Commission projects depend on the meeting calendar, completeness, revisions, and the scope under review.

What Can Slow the Process?

The preventable delays are usually the boring ones: an incomplete scope, missing photographs, unclear materials, missing drawings, or a contractor proposal that does not match the application. Larger or more sensitive projects can also move to ARC or Commission review. Separate building-permit issues can add time even after HDLC has finished its part.

What Does HDLC Approval Cost?

The current City CofA page says HDLC itself does not collect a fee for the Certificate of Appropriateness. It also states that Safety & Permits adds a 50% surcharge to the permit fee, plus the applicable plan-checking fee, for work requiring HDLC review. Other design, professional, permit, material and construction costs are separate and depend on the project.

Before Work Starts: A Historic-Property Owner Checklist

• □Confirm which historic-review agency has jurisdiction over the property.
• □Verify the address and district or landmark status using current City resources.
• □Write down the complete exterior scope, including repair-in-kind.
• □Review the Design Guidelines that apply to the proposed work.
• □Confirm whether the project needs a CofA, a building permit, or both.
• □Submit the current required documents and resolve staff questions.
• □Keep the approved materials and details aligned with the contractor’s actual scope.
• □Obtain the written approvals required for the work before construction begins.
• □Do not assume a contractor’s past experience replaces approval for this property and scope.
• □Ask the agency before making a material change to the approved exterior work.

What If Exterior Work Has Already Started?

Don’t keep working on the assumption that approval can be sorted out later. Contact the applicable historic-review and permitting offices promptly, describe what has already been done, and ask for current project-specific instructions. The City has review routes for work completed in violation, but the consequences and required corrective steps depend on the facts. This guide does not give an enforcement or penalty estimate.

Buying a Historic Property for Renovation or Redevelopment? Do Due Diligence Before You Close

If the value of a deal depends on removing a building, changing a façade, adding substantial new floor area, or making major structural alterations, approval risk belongs in the purchase analysis—not after closing. The City’s demolition guidance strongly recommends against buying a property in anticipation of demolishing it without prior HDLC approval.

• □Verify whether the property is in a local historic district, the Vieux Carré, a National Register district, or more than one of these contexts.
• □Confirm the applicable control level and which agency will review the intended work.
• □Compare the development concept with the current Design Guidelines and demolition-review criteria.
• □Ask HDLC or VCC about the specific property before assuming a demolition or major-alteration path.
• □Build design, permitting, professional-review, and meeting time into the transaction plan.
• □Do not treat a seller, broker, contractor, or prior project as a substitute for current City confirmation.

For an out-of-state owner or investor, this step matters even more because historic-review terms that sound familiar can mean something different in New Orleans than they do in another city.

New Orleans HDLC Approval FAQs

Need Local Help Coordinating a Historic Property Project?

Historic-property work often involves more than one moving part: contractors, materials, tenant or ownership needs, permit sequencing, and communication with the professionals working on the project. Once you have confirmed the City review path, the next question is who will keep the project scope and day-to-day coordination organized.
