About the Alteration Agreement Process
What triggers an Alteration Agreement?
Any work that goes beyond cosmetic improvements — structural changes to walls, floors, or ceilings; plumbing modifications; electrical work beyond cosmetic replacements; HVAC changes; window or building envelope modifications; or any work requiring a NYC Department of Buildings permit or architect filing.
What does the process involve?
Initial submission to property management — The shareholder submits a description of the proposed work, along with any preliminary plans or drawings, to the Resident Manager and managing agent (AKAM Associates) for initial review.
Engineering and architectural review — Property management coordinates with the building's engineer and/or architect to evaluate the proposed scope. This may involve reviewing structural drawings, mechanical plans, or other technical documentation submitted by the shareholder's contractor or architect.
Walkthroughs and site visits — Depending on the scope, a walkthrough of the apartment may be required so that the building's engineer or architect can assess existing conditions and confirm that the proposed work is feasible and will not affect building systems or other units.
Review and revision — All parties — the shareholder, their contractor or architect, property management, and the building's engineer — communicate until the scope is agreed upon and any required modifications to the plans are resolved.
Board approval and agreement execution — Once all parties are in agreement, the formal Alteration Agreement is prepared, reviewed by the board, and executed by both the shareholder and the building. Insurance requirements, any required security deposit, and permit obligations are confirmed at this stage.
Scheduling approval — Only after the Alteration Agreement is fully executed will the Resident Manager approve scheduling requests through this portal. Work may not begin before this point.
How long does it take?
The timeline varies based on scope complexity and how quickly all parties can align. Simple projects may be resolved in a few weeks; larger or more complex renovations involving multiple review rounds and walkthroughs can take 6–12 weeks or more. Shareholders are strongly encouraged to begin this process well in advance of their intended start date.
