TR1 Progress Inspection Services: What They Cover

For a small NYC renovation, the inspection process can feel disproportionate to the project itself. A restaurant fit-out, apartment alteration, or certificate-of-occupancy update still needs clear documentation, scheduled inspections, and dependable reporting.

TR1 progress inspection services help verify that required construction work matches the approved drawings and applicable NYC requirements. Depending on the filing, the service may include preliminary and final inspections, progress inspection reports, and DOB NOW reporting. NYC rules generally require progress inspectors to review at least 15% of the work for a given inspection. Plus at least one of each unit type, unless the applicable rule provides otherwise. NYC Department of Buildings guidance also requires owners to retain qualified professionals without a project conflict of interest.

AKS Architectural and Engineering Services, LLP is a Class 2 Special Inspection Agency focused on small and mid-size projects, typically under 4,000 square feet. Its EZTR1 service model combines menu pricing with online checkout, helping owners, contractors, and design professionals move from project details to inspection coordination without a prolonged quote process. The service begins with understanding exactly what the TR1 process must document.

What TR1 Progress Inspection Services Cover

A TR1 progress inspection service is a practical compliance review that connects the approved construction documents with the work taking place on site. For owners, contractors, and design teams, the value is not simply having an inspector visit the project. It is having the required observations documented, reported, and coordinated so the project can move toward sign-off without avoidable gaps.

AKS Architectural & Engineering Services, LLP provides this service for the small and mid-size NYC projects it is equipped to support. The inspection scope is based on the approved drawings, the applicable NYC Construction Code requirements, and the inspection stages identified for the project.

What the inspection work includes

• Approved-document review:

  Special inspections verify that selected materials, equipment, installations, fabrication, erection, or component connections comply with the approved construction documents and referenced standards under BC 1702.1. See the NYC Department of Buildings

  special inspections requirements

  for the governing framework.

• Energy Code progress checks:

  Progress inspections for Energy Code compliance are mandated by Section BC 109.3.5 and 1 RCNY 5000-01. The approved drawings should identify the inspection requirements and allow the contractor to schedule the work appropriately.

• Representative observation:

  Unless an exception applies under Tables I or II of 1 RCNY 5000-01. The progress inspector must inspect at least 15% of the construction work for a given progress inspection and at least one of each unit type. The exact field review depends on the project documents and inspection category.

• Condition tracking:

  If installed work differs from the approved drawings enough to prevent an adequate inspection. The inspector must wait until the drawings and energy analysis are updated and approved as appropriate. This protects the integrity of the inspection record instead of treating an unresolved discrepancy as compliant.

• Reporting and coordination:

  The service includes preparing TR1 progress inspection reports and supporting the required DOB NOW reporting process as applicable to the project. The work may involve preliminary and final inspection stages, depending on the filing and construction status.

The owner is responsible for retaining a registered design professional to perform progress inspections, and that professional must not have a conflict of interest on the project. That requirement makes selection important: the inspector needs both the appropriate qualifications and a clear understanding of the approved scope.

For a practical overview of how the filing and field requirements fit together, review these TR1 inspection requirements. Then, when the project is ready to arrange service, AKS can organize the inspection around the documented scope rather than a vague, open-ended site visit.

When Is a TR1 Progress Inspection Required in NYC?

A TR1 progress inspection is generally required when the approved construction documents call for progress inspections, including inspections tied to Energy Code compliance. In practical terms, owners, general contractors, and architects should plan for these reviews before covered work is concealed or completed. New York City Building Code Section BC 109.3.5 and 1 RCNY 5000-01 establish requirements for Energy Code progress inspections. While the approved drawings identify the work and timing that must be inspected.

The key question is not simply whether a project is large. Tenant fit-outs, restaurant renovations, interior alterations, and additions can all require documented reviews. If field conditions differ from the approved drawings enough to prevent an adequate inspection. The progress inspector must wait until the drawings and applicable energy analysis are updated and approved. See the NYC Department of Buildings progress inspection requirements for the governing guidance.

Which small projects commonly need a review?

Many small and mid-size projects need progress inspections because the work affects building systems, energy-related construction, or other items identified in the approved documents. Common examples include:

• Tenant fit-outs:

  Restaurant, retail, office, hospitality, and similar interior build-outs may include covered work that must be verified as construction proceeds.

• Interior alterations:

  Apartment renovations and other changes to existing spaces can require inspections when the approved plans identify progress-inspection items.

• Additions and renovations:

  A residential or commercial addition, including work connected to a change in use, may require inspections at specified stages.

• Energy-related construction:

  Progress inspections required under BC 109.3.5 must be detailed in the construction drawings so the contractor can schedule access before work is covered.

For a project to move smoothly, the owner should retain a qualified registered design professional without a conflict of interest. The TR1 form assigns responsibility for required special inspections and related inspection duties. So the design team and contractor should review it early rather than treating it as a closeout form.

What does the inspector actually review?

Progress inspections verify that installed work matches the approved drawings. Unless an exception applies under the applicable tables in 1 RCNY 5000-01. The inspector must observe at least 15% of the construction work for a given progress inspection and at least one of each unit type. The inspection is therefore a documented sample of real installed work, not a quick administrative sign-off.

Takeaway: Schedule TR1 progress inspection services when the approved plans require them, before covered work makes verification difficult, and coordinate the inspection points with the construction schedule.

Preliminary vs Final TR1 Inspections and DOB NOW Reporting

The TR1 is the central NYC document used to identify and assign responsibility for special inspections required under Building Code Chapter 17. A preliminary review and a final progress inspection serve different points in the project. Treating them as the same service can create confusion about who is responsible, what must be inspected, and when reporting can be completed. The official TR1 form provides the framework for documenting those responsibilities.

Key takeaway: The preliminary TR1 review establishes the inspection path; the final review confirms the built result and supports accurate reporting.

Why approved drawings matter to DOB NOW reporting

Final reporting is only as reliable as the documents used to evaluate the work. NYC guidance states that progress inspectors must verify construction against the approved drawings. If the construction differs enough that the inspection cannot be adequately performed. The inspector must wait until the drawings and applicable energy analysis are updated and approved before beginning the inspection. This protects the owner and contractor from filing a report that does not match the project record.

For that reason, the project team should flag design changes before requesting the final inspection. Updated drawings, field conditions, and the TR1 responsibility assignments should tell the same story. Resolving discrepancies early is more efficient than discovering them during a final visit or while preparing DOB NOW documentation.

Choosing the right TR1 service for a small project

For a small commercial or residential project, a preliminary review can clarify the required scope before work progresses. AKS Architectural and Engineering Services, LLP, a Class 2 Special Inspection Agency focused on smaller projects, offers an online TR-1 preliminary inspection product. The service is designed for a straightforward process: select the project type and size, identify the needed service, and proceed through online checkout.

Using TR1 progress inspection services at the appropriate stage gives the project team a clearer path from responsibility assignment to completed verification and DOB NOW reporting.

How AKS Delivers TR1 Progress Inspection Services for Small Projects

Small construction projects still carry serious inspection and filing responsibilities. AKS Architectural and Engineering Services, LLP is structured to help owners, contractors, architects, and engineers manage those requirements without the delays and complexity often associated with larger firms. As a Class 2 Special Inspection Agency, AKS focuses on practical code-compliance work for small and mid-size projects, typically under 4,000 square feet.

Use this NYC progress inspection checklist to organize your project before the first site visit.

A service built around the project schedule

AKS coordinates scheduled site visits around the work that needs to be observed. Progress inspectors verify that construction meets the approved drawings and that the inspection activities can be completed at the appropriate stages of the project. NYC guidance states that, unless an exception applies under the applicable rule tables. Progress inspectors must inspect at least 15% of the construction work for a given progress inspection and at least one of each unit type. The contractor therefore needs to allow inspection time in the construction schedule, rather than treating the visit as an afterthought.

For projects where the built work differs from the approved drawings, the inspection may need to wait until updated drawings and related approvals are in place. That makes early coordination valuable, especially on apartment alterations, commercial fit-outs, renovations, additions, and other small projects where schedule changes can affect several trades at once.

Deliverables that keep reporting organized

• Scheduled inspections:

  AKS arranges the required TR1 progress inspection visits and documents the observed work.

• Preliminary reporting:

  The preliminary TR1 inspection report identifies the inspection status and any items that need attention before closeout.

• Final reporting:

  The signed final TR1 report provides a clear record of completed inspection work for the project team.

• DOB NOW support:

  Reporting and filing information is organized for the DOB NOW compliance process, helping owners and professionals keep the project record current.

For background on the broader role of an inspector, see this guide to choosing an NYC special inspection agency. The goal is not to add paperwork for its own sake. It is to give the responsible parties a usable record of what was inspected, what remains open, and what is ready for final reporting.

Simple ordering for smaller clients

AKS uses transparent menu pricing and an online click-and-pay process. A customer selects the project type, chooses the project size, identifies the services needed, and proceeds to payment without waiting for a traditional quote. This digital-first model is especially useful for smaller owners and contractors who need a defined inspection service quickly, with deliverables that match the project stage.

What Does a TR1 Progress Inspection Cost at EZTR1?

The cost of TR1 progress inspection services depends on the project details and the services required. EZTR1 is designed to make that answer easier to find. Instead of waiting through repeated calls and emails for a traditional quote, you can review menu pricing online and begin with the details that affect your inspection needs.

Visit the EZTR1 online shop to review available inspection options and start your order.

Why EZTR1 uses menu pricing

A TR1 inspection is connected to the scope of work, project type, project size, and the services selected. A small commercial fit-out, apartment alteration, or other code-compliance project may not require the same inspection path as a larger or more complex job. For that reason, a single generic price would not give every owner or contractor a useful answer.

EZTR1 presents the selection process in a straightforward format. You select your project type, choose the project size, and select the services needed from a dropdown menu. The available price is then tied to those selections, giving you a clearer starting point before you move forward.

• Project type:

  Identify the kind of construction or alteration involved.

• Project size:

  Choose the size category that matches the work.

• Services needed:

  Select the inspection services relevant to the project.

• Online checkout:

  Review the order and click to pay without waiting for a separate quote response.

What is included in the online buying experience?

The e-commerce flow is meant to reduce uncertainty at the beginning of a project. You can see the available service option, understand what you are selecting, and proceed online rather than coordinating an extended quote process with a busy individual practitioner. That convenience is especially useful for owners, architects, contractors, and property managers handling smaller projects on a schedule.

EZTR1 operates under AKS Architectural and Engineering Services, LLP, a Class 2 Special Inspection Agency focused on small and mid-size work, typically under 4,000 square feet. The agency's service model combines that project focus with approximately 40 years of NYC construction-industry experience. If you already know that you need a preliminary TR1 inspection, review the TR-1 preliminary inspection product page for the applicable selection and checkout path.

Menu pricing does not replace project-specific review when the scope changes. If the work, drawings, or requested services differ from the original selection, confirm the appropriate inspection path before scheduling. The advantage is that you can begin with a transparent, organized purchase process instead of an open-ended request for a quote.

Getting TR1 Progress Inspection Services for Your Small NY Project

Starting a TR1 inspection should not require a long chain of unanswered calls or an open-ended quote. For a small renovation, fit-out, alteration, or similar NYC project, AKS Architectural and Engineering Services. LLP gives owners and general contractors a straightforward way to identify the service needed and move the project forward.

Choose the inspection service that matches your project, then arrange it before the work reaches the inspection milestone.

Use the online service menu

The EZTR1 online process is designed around the information a project team already knows. Select the project type, select the project size, choose the services needed from the menu, and click to pay online. This approach makes the initial order more predictable and helps avoid the delays that can come with waiting for a traditional custom quote.

• Project type:

  Identify whether the work involves an interior alteration, tenant fit-out, renovation, addition, or another project category.

• Project size:

  Select the size range that reflects the scope of the work so the service is matched to the project.

• Services needed:

  Choose the TR1 inspection service and any other applicable inspection needs shown in the menu.

• Online payment:

  Complete checkout so the inspection request can be coordinated with the construction schedule.

Confirm that the agency fits the project

AKS operates as a Class 2 Special Inspection Agency, with a focus on the smaller projects that are often poorly served by large-agency processes. The company's typical project focus is under 4,000 square feet. Class 2 agency limitations also mean that AKS is not the right choice for major building work, full demolitions, or large-scale expansions exceeding 10,000 square feet. Confirming the project scope at the start helps prevent an avoidable mismatch.

That focused service model is supported by approximately 40 years of NYC construction-industry experience. Owners, contractors, architects, and engineers can work with a team familiar with the practical coordination required for code-compliance inspections. While still using a digital ordering process suited to smaller jobs.

Coordinate the inspection with the construction schedule

After ordering, keep the approved drawings, project information, and construction schedule available for coordination. Progress inspectors verify that the construction meets the approved drawings, and the inspection must be planned when the relevant work is visible. If field conditions differ from the approved drawings in a way that prevents an adequate inspection, updated and approved drawings may be needed before the inspection proceeds. Early coordination gives the project team time to address that issue rather than discovering it after work is covered.

For owners and GCs who need a clear starting point, the online menu keeps the next step simple: define the project. Select the service, and arrange the inspection with a provider built around small-project compliance.

Frequently Asked Questions

When are TR1 special inspections required?

TR1-related inspections are required when the approved construction documents and NYC code identify progress or special inspections for the project. The exact scope depends on the work shown in the approved drawings, so the owner. Design team, and contractor should confirm inspection requirements before construction reaches the relevant stage.

What is the difference between progress and special inspections?

Progress inspections verify that construction follows approved drawings and required progress-inspection details. Special inspections focus on selected materials, equipment, installations, fabrication, erection, or component connections under the applicable code requirements. They may be separate services, even when one project needs both.

How much construction work does a progress inspection review?

Unless an exception applies under Tables I or II of 1 RCNY 5000-01. The inspector must review at least 15% of the construction work for a given progress inspection and at least one of each unit type. See the NYC Department of Buildings progress-inspection guidance for the governing standard.

Can a small NYC renovation use a Class 2 inspection agency?

Yes, when the project fits the agency's permitted scope. AKS Architectural and Engineering Services, LLP operates as a Class 2 Special Inspection Agency and focuses on small and mid-size projects, typically under 4,000 square feet.
