Accessibility alterations help people enter, use and move through buildings, including historic properties where entrances and circulation routes were designed before modern accessibility standards. The New York City Landmarks Preservation Commission (LPC) may review a ramp, lift, altered door, handrail or other change to a designated facade or significant interior landmark.
The goal is to address applicable accessibility requirements while protecting the historic building as far as reasonably possible. LPC review is separate from the legal and technical accessibility standards administered through building codes and other laws; owners should involve the qualified professionals appropriate to the scope.

Barrier-free access generally describes features that help a person with mobility needs enter and use a building, such as an accessible route, ramp, lift, landing, door or properly coordinated threshold. On a landmark, the change may affect a protected stoop, ornamental railing, entrance or historic stone surround.
LPC’s permit guidance includes barrier-free access work and recognizes the need to adapt historic properties. The review examines whether the proposed design can achieve the project goal with suitable materials, attachment and treatment of significant historic features.
Begin with a site survey that accurately records entry levels, door clearances, steps, sidewalks and the historic materials affected. The professional team evaluates accessibility solutions and their effects on the landmark. Portico documents the selected approach using existing/proposed plans, elevations, photographs and details.
A qualifying ramp or other DOB-permitted project may be considered for a Certificate of No Effect if it meets LPC standards and does not adversely affect significant features. Other schemes may require staff revisions or Commission review. The agency, not the applicant, determines the permit route.
DOB reviews applicable construction and accessibility requirements; federal, state or City accessibility laws may involve additional responsibilities beyond LPC’s historic character review. A preservation approval does not excuse compliance with those laws, and SLK should not offer legal opinions about them.
A front-stoop project might also occupy or alter the sidewalk, where DOT or other public-right-of-way permissions apply. The building team should identify boundary lines, existing conditions and the agency for each approval before selecting a final design.
Several concepts may be worth documenting: a reversible ramp, a side entrance, a modified door arrangement or another appropriate route. The qualified team should decide which options are technically and legally workable for the actual property.
For a business, accessibility alterations may be coordinated with LPC Business Express when its eligibility applies. Commercial operating and construction permissions remain separate.
SLK Buildings assists property owners, building managers, developers, business operators and project teams with accessible entrance application records, historic design coordination and separate technical professional review. For an initial conversation, share the property address, available photographs, proposed work, existing LPC or DOB permit numbers, and any relevant agency correspondence. SLK can help organize the filing, coordination and next actions, while LPC and the other responsible agencies make their own determinations and licensed professionals carry out the work legally reserved to them.

New York City Landmarks Preservation Commission (LPC) requirements can affect a proposed alteration even when the project appears minor. Owners and project teams may need to confirm landmark designation, identify protected features, gather existing-condition photographs, prepare drawings and material information, and obtain LPC approval before starting regulated work.
LPC requirements may intersect with DOB construction permits, DCP zoning or land-use approvals, DOT sidewalk and street permissions, and OATH enforcement proceedings. The correct path depends on the designated property, the proposed scope, the applicable permit category, and whether staff review or a Commission hearing is necessary.
SLK Buildings assists with LPC application coordination, permit expediting, Portico submissions, records research, related professional coordination, agency comments, alteration approvals, landmark violations, and associated multi-agency filings within its confirmed scope of services.
Whether a project is at the research stage, awaiting an LPC response, being revised for a preservation concern, or addressing unauthorized work, maintaining consistent records and clear next actions can help the team coordinate the required approvals.
SLK Buildings provides free educational content to help property owners, business operators, developers, architects, contractors, and project teams understand LPC designation, current permit categories, Portico filing, historic-district alterations, hearings, violations, professional roles, and related DOB and other agency requirements.
For those who prefer professional assistance, SLK Buildings is available to coordinate LPC records review, filing-path research, application preparation, Portico submissions, agency comments and follow-up, design-professional coordination, permit and violation tracking, and connected NYC agency obligations. Final determinations and applicable professional work remain with the appropriate agency and qualified providers.

Often an appropriate design can be evaluated, but LPC review and applicable construction/accessibility rules must be considered.
No. The applicable accessibility standards and legal duties are separate from LPC preservation review.
Possibly, with suitable documentation of protected features, door design, clearances and any necessary DOB review.
Eligible street-level commercial ramp, lift or entry work is included in LPC Business Express work types.
That depends on the scope and code requirements; the design team should independently determine DOB obligations.
