Apartment construction has a building process alongside design and agency work. AZRL NYC serves Manhattan and Brooklyn as a licensed general contractor and offers a free walkthrough and estimate for co-op and condo renovations.
Why apartment projects need early coordination
A renovation in a co-op or condo has two parallel tracks: the design and construction plan, and the building’s review process. The board, managing agent, and building architect or engineer may review drawings, scope, contractor records, insurance certificates, schedule, and logistics. Requirements vary, and the current alteration agreement is the source for property-specific rules.
A project can be ready on paper but still need revisions to satisfy the building. Confirm submission format, required signatures, review sequence, deposits, permitted hours, and any seasonal restrictions before committing to a mobilization date. Board review can take weeks. Starting the package early gives the owner and architect a chance to resolve questions before ordering materials.
What an alteration agreement covers
The alteration agreement commonly sets conditions for work inside the unit and the protection of shared areas. It may address scope approval, insurance, deposits, work hours, noise, debris, plumbing shutoffs, elevator booking, corridor protection, and required inspections or sign-offs. Some buildings also set rules for wet-over-dry work, gas, ventilation, and periods when construction is limited.
Read the agreement with the managing agent and design team, then turn each requirement into a project action. For example, an elevator rule needs a reservation process; a protection rule needs a defined installation and removal scope; and an insurance requirement needs the correct certificate wording. Do not assume another building’s forms or terms will apply.
Contractor package and professional roles
The construction side of a submission may include a written scope, schedule, contractor information, and certificates of insurance naming parties as the building requires. The architect supplies drawings and design responses; the expediter advises on filings; the contractor coordinates construction details and building logistics. The exact package is set by the agreement and managing agent.
Insurance documentation should be prepared by the relevant broker or insurer using the building’s instructions. We coordinate construction questions with your architect or expediter and the building, while licensed design professionals prepare drawings and required filings. Before submission, compare the package against the building checklist so that revisions do not arise from missing forms or outdated scope.
DOB NOW board attestation
For Condo Unit Owner and Co-Op Tenant-Shareholder filings, the DOB NOW: Build workflow changed on February 2, 2026. A board representative now participates in the filing and records that the board authorized the applicant. This city workflow is distinct from the building’s alteration process.
The owner, architect, and expediter should account for the attestation when planning filing readiness. Confirm who will request the board authorization and who will complete the agency workflow. Read the DOB service notice. The notice describes the system change; the project’s registered design professional confirms how it applies to the filing.
Building logistics and close-out
Reserve the service elevator, confirm delivery windows, install protection, and agree on debris routes before the first trade arrives. Coordinate access with the superintendent and give the building the notices it requests. Noise limits and work hours affect sequencing, especially when several trades need access during a narrow daily window.
At completion, the building may request inspection, sign-off documents, proof of permit close-out, removal of protection, or confirmation that shared areas are restored. Keep a close-out list that names the responsible person for each item. Your architect or expediter confirms agency sign-off; the managing agent confirms building requirements.
Planning and estimate factors
The scope, finish selections, building review, elevator access, work-hour limits, and existing conditions all affect planning. Wet-over-dry restrictions or limits on exhaust and gas can lead to design changes before construction. A walkthrough can surface visible constraints, but drawings and professional review may be needed to confirm systems and filing requirements.
Our sequence is conversation, walkthrough and estimate, build, and handover. Before work starts, align the design, building package, required filings, selections, and site rules. The related alteration agreement guide includes a checklist for owners preparing a submission.
Frequently asked questions
What is an alteration agreement?
It is a building’s written set of requirements for proposed unit work. It can address scope review, insurance, deposits, hours, access, protection, and close-out.
How long does board review take?
It varies by building and submission. Review can take weeks and may involve comments or revisions, so ask the managing agent for the current process.
What documents go in the package?
The building may request drawings, a scope, contractor information, certificates of insurance, schedule, signatures, and deposits. Follow its current checklist.
What changed in DOB NOW on February 2, 2026?
The DOB notice describes a new board-participation step for certain owner categories. The representative records authorization in the filing system; the project’s registered design professional can confirm whether that workflow applies.
Can work happen during summer?
Some buildings restrict work seasonally; others set different conditions. Confirm the rule and any exceptions with the managing agent.
Who confirms permit sign-off?
The architect or expediter confirms agency filing and sign-off requirements; the managing agent confirms separate building close-out requirements.
Deposits, work periods, and owner coordination
Buildings may require refundable deposits or other charges, but amounts and terms are property-specific. Ask what triggers release, which documents are needed, and who confirms that protection has been removed and common areas restored. Record these responsibilities with the owner and managing agent rather than assuming release happens automatically.
Some buildings limit construction during particular seasons, holidays, or occupied periods. Confirm the current calendar before selecting a start window. If a scope changes after approval, check whether revised board documents, insurance certificates, or agency filings are required. Keep one current approved scope available to the superintendent and trades.
