Understand what the agreement controls.
The alteration agreement is a private document governing renovation between the owner and the co-op, condominium, landlord, or building entity. It may incorporate house rules, design standards, insurance instructions, contractor requirements, fees, deposits, damage responsibility, access procedures, and remedies for noncompliance. It is separate from the construction contract and government permits.
Owners should read the complete current package and obtain legal advice when appropriate. Contractors should review the sections that affect scope, logistics, documentation, time, and site conduct. Neither party should rely only on a summary because important requirements may appear in schedules, exhibits, insurance samples, or management forms.
Confirm which work the building is being asked to approve.
The application may require a written scope, drawings, specifications, product data, demolition notes, acoustic information, wet-area details, equipment information, and public filing status. The contractor proposal should align with those materials. If the project has alternates or future phases, clarify whether they are included in the requested approval.
Changes after approval may need resubmission. Establish who decides whether a revision is material, who updates the documents, and whether construction must pause. A building approval based on outdated information can expose the owner and contractor to disputes or rework.
Identify every party named in the process.
The agreement may assign obligations to the unit owner, shareholder, tenant, board, managing agent, building architect or engineer, contractor, subcontractors, design professionals, and insurers. Create a contact and responsibility matrix using the exact legal names. Determine who may issue direction and who has authority to approve changes.
The owner should avoid forwarding building requests without assigning them. A design comment belongs with the appropriate architect or engineer. A certificate request belongs with the insurance broker. A permit question belongs with the qualified professional or licensee. A logistics request belongs with the contractor and management. Routing correctly shortens the response cycle.
Translate working-hour rules into a realistic schedule.
Agreements can restrict daily hours, noisy work, weekends, holidays, elevator access, shutdowns, deliveries, demolition periods, or total project duration. They may require advance notice for certain activities. These restrictions reduce the theoretical production time and should be visible in labor planning and milestone dates.
Some documents include daily or periodic charges for work extending beyond an approved period. Others require extensions or renewed submissions. Review these provisions early and seek legal guidance for interpretation. The construction schedule should show the assumptions used rather than promising a date based on unrestricted access.
Define protection, conduct, and damage procedures.
Common-area protection can include entrance paths, corridors, elevators, stairs, doors, floors, walls, and service areas. The agreement may regulate material movement, carts, debris, dust, water shutoffs, noise, smoking, worker access, identification, restroom use, and daily cleaning. The contractor must price and supervise these conditions.
Document existing common-area conditions when appropriate and establish how damage is reported, secured, evaluated, and repaired. The goal is not only to avoid charges; it is to keep the building safe and functional while preserving a clear record of responsibility.
Send insurance language to qualified insurance professionals.
Alteration packages may include certificate samples, required policy types, limits, additional insured names, endorsements, waiver language, and cancellation conditions. Contractors should submit the exact instructions to their brokers. Owners and contractors should not alter an insurance document or assume a certificate alone proves every requested term.
Determine whether subcontractors must submit separate evidence, whether policies must remain active through closeout, and how renewals are handled. Insurance review should be a scheduled approval step because correcting entity names or obtaining endorsements can take time.
Track deposits, fees, professional review, and building charges.
Buildings may require refundable deposits, nonrefundable processing charges, professional review fees, move or elevator charges, security or staffing costs, or damage assessments. Identify who pays each item and whether it belongs inside or outside the contractor's price. Do not assume every building charge is a construction cost carried by the contractor.
Record conditions for deposit release and possible deductions. The owner should retain submissions, approvals, inspection results, payment records, and closeout correspondence. If the agreement contains penalties, indemnity, legal-fee, or dispute provisions, legal counsel should advise the owner rather than the contractor interpreting them.
Create the closeout checklist before work starts.
The agreement may require final inspections, permit signoffs, architect or engineer letters, plumbing or electrical documentation, contractor affidavits, warranties, product information, photographs, cleaning, protection removal, keys, and confirmation that common areas are restored. Assign each requirement to a party and a target date.
Do not wait until final payment to learn what management expects. A complete closeout package supports deposit release and demonstrates that the approved renovation, building obligations, and public requirements have been addressed. Keep the final accepted package with the owner's property records.
- Read every exhibit and work rule
- Align the approved and contracted scopes
- Assign submissions by responsible party
- Price access and protection requirements
- Track fees, deposits, and renewals
- Define final inspection and document requirements
Turn this guide into a working project record.
Begin with a short owner brief rather than leaving important details scattered across browser tabs or conversations. Record the complete property address and unit, legal or management contacts, current occupancy, affected rooms or commercial areas, desired result, elements that must remain, photographs, available drawings, known damage, previous alterations, target timing, and every document already received from the building or landlord. Date the brief and identify which information is confirmed, assumed, or still missing.
Next, separate decisions into four categories: confirmed base scope, owner selections still required, optional alternates, and conditions needing investigation. Give each open item a responsible person and a decision date tied to the work it controls. A product decision may affect rough locations or fabrication; a building comment may affect access or protection; a professional review may affect whether pricing can be fixed. Recording that dependency makes the consequence of delay visible before the field is waiting.
Create a responsibility matrix for design, filing, permits, building submissions, insurance, purchasing, delivery, licensed and specialty trades, protection, testing, patching, cleaning, inspections, punch list, and closeout. Use exact legal entities where contracts, permits, licenses, or insurance are involved. The matrix is not a substitute for professional advice; it is a way to expose responsibilities that otherwise fall between parties.
Finally, give the same project package to every contractor or consultant being evaluated. Issue clarifications consistently, retain prior versions, and keep one current decision log. Review official requirements near the time of the project because agency procedures, building requirements, products, and property conditions can change. A strong record helps the owner ask better questions, compare the same promise, and identify when more design, investigation, or qualified advice is needed before construction.

Common project questions.
What is an alteration agreement?
It is a private agreement governing renovation between an owner and a co-op, condominium, landlord, or building entity. It can address scope, approvals, insurance, access, protection, deposits, conduct, damage, and closeout.
Should the contractor read the alteration agreement?
Yes. The contractor should review provisions affecting scope, insurance, work hours, deliveries, protection, debris, shutdowns, staffing, supervision, and closeout before final pricing and scheduling.
Does signing an alteration agreement provide a DOB permit?
No. Building authorization and government approvals are separate. The project team must determine and complete every applicable building, agency, professional, and licensed-trade requirement.
Who pays the building's renovation fees and deposits?
The agreement and construction contract should state responsibility. Owners often have direct obligations to the building, while contractor pricing may include specific logistics or documentation. Never assume without documenting it.
Can the scope change after board or management approval?
Possibly, but the building may require notice, revised drawings, professional review, additional fees, or a new approval. Confirm the procedure before changed work proceeds.
Who should interpret legal language in an alteration agreement?
An attorney should advise the owner on legal rights, indemnity, penalties, disputes, and other legal terms. Contractors can identify construction and logistics effects but should not substitute for legal advice.
