Commercial Alteration Approval in NYC Buildings

Building documents, property governance and project scope determine what materials and reviews may apply. Use the current documents for the actual property; this reference is not legal advice, a permit determination or approval.

Building coordination

Commercial tenant and landlord alteration planning

01

Commercial tenant and landlord alterations

A tenant improvement conversation starts with the lease boundary, landlord work letter, existing building documents and specific scope. Clarify which party controls shared or base-building systems and who reviews the tenant submission.

02

Identify governing documents

Ask the owner or authorized building representative which current bylaws, house rules, contracts or alteration requirements apply to the commercial interior scope.

03

Define the commercial tenant and landlord scope

Identify the lobby, hallway, corridor or other shared space, the proposed work and the boundaries of the project request.

04

Confirm the review parties

The landlord or property manager, owner representative, architect/designer, engineers, contractors and procurement contact may hold distinct responsibilities. Confirm who owns each decision.

05

Verify filings and technical requirements

Applicable filings, permits, insurance and professional responsibilities depend on the defined scope and actual property. Obtain confirmation from the responsible design professional and applicable authority.

06

Keep decisions documented

Record the current requirements, submitted scope, reviewer questions and written decisions in the approved project record. No approval or timeline is promised by this guide.

Commercial / project planning

Contact the commercial project team

Share project location, scope and available documents. Do not email confidential plans or bid files.

Use a building-specific planning discussion to organize current commercial tenant and landlord scope, building documents and responsible project-team questions.

Have a space that has to stay open while it's renovated?

Send the address, the scope and your drawings or photos. Waldy Corniel reviews every inquiry personally.
