I run a NYC compliance software company, so I am not a neutral party. But I am going to write this piece honestly, because the alternative — spreadsheet versus consultant versus platform — is a real choice that owners face, and the framing matters more than any single product. Each of the three approaches works for some portfolios. Each fails for others. Here is a straight comparison.
The three options, briefly
The spreadsheet. A property manager maintains a workbook. Each tab is a building, or each row is a deadline. Someone updates it when they remember. The cost is internal staff time. Almost every NYC owner starts here.
The consultant. An outside firm — a compliance specialist, a property management company's compliance group, an expediter, or a law firm — owns the calendar for you. They send reminders, file the reports, and bill hourly or on a flat retainer.
The software platform. A SaaS tool that maps your buildings to applicable laws, maintains the deadline calendar, alerts you, and stores documentation. The owner or property manager remains in the workflow but the system handles the structure.
These are not mutually exclusive. Many owners use a combination. The right blend depends on portfolio size, sophistication of in-house staff, and how much you trust your memory.
What spreadsheets are good for
Spreadsheets work — for a while.
Strengths:
- Zero subscription cost.
- Familiar to everyone.
- Customizable to whatever the team thinks is important.
- Portable; you can take it with you.
Where it breaks:
- Single-author dependence. The spreadsheet is only as good as the person maintaining it. When that person leaves, takes a vacation, or simply forgets one Tuesday, the system fails silently.
- No alerts. A spreadsheet doesn't email you when a deadline is approaching. You have to check it. Most people don't.
- Versioning. Every email-around-the-spreadsheet workflow generates conflicting copies. Within six months, nobody knows which one is current.
- No agency cross-reference. When DOB publishes an updated FISP sub-cycle list, the spreadsheet doesn't know. Someone has to read it and update.
- Document storage is separate. Reports, certifications, photos all live somewhere else. Reconciling the spreadsheet to the actual documents takes time.
The honest assessment: a spreadsheet works for an owner with one or two buildings, a single property manager who has been on the job for years, and a high tolerance for personal-memory dependence. For anything bigger, the spreadsheet quietly accumulates errors that surface during audits or transactions.
What consultants are good for
A good compliance consultant or expediter is genuinely valuable. The best ones know more about specific rules than most platforms can encode.
Strengths:
- Expert judgment. A consultant can read a violation notice and tell you in 90 seconds whether to certify, contest, or escalate. That kind of judgment is hard to automate.
- Filing experience. They have submitted hundreds of these reports. They know the portal quirks, the inspector preferences, the language that lands well at OATH.
- Specialization. A facade specialist for FISP, an energy professional for LL87, a fire safety expert for FDNY filings. You get depth where you need it.
- They do the work, not just track it.
Where it breaks:
- Cost scales with portfolio. Every additional building is an additional engagement. For a 50-building portfolio, the annual consulting bill is substantial.
- Knowledge stays with the consultant. When the engagement ends or the consultant moves on, you don't necessarily inherit their workflow.
- Deadline tracking is often a side effort. Most consultants are paid to file specific reports — not to maintain a 360-degree compliance calendar across all your obligations.
- Reactive rather than proactive. A consultant filing your LL97 report in April is not the same as a system that watched your benchmarking data drift in November and flagged it.
- Vendor lock-in. Some consultants store your records in their own systems. Switching firms means data migration headaches.
The honest assessment: consultants are essential for the substantive expertise — the actual engineering, the QEWI inspection, the OATH defense — and weak as the front-line tracking system. Don't ask the consultant to be your calendar.
What software platforms are good for
This is where I have a stake. Let me try to write it fairly.
Strengths:
- Cross-portfolio visibility. Every building, every law, every deadline, in one view.
- Automated detection. A good platform applies the rules engine to your portfolio and tells you what laws apply — including the ones you didn't know about.
- Alerts and follow-up. Deadline approaching? You get notified. Document expiring? You get notified. Inspection result not yet uploaded? You get notified.
- Document vault. Reports, certifications, photos all attached to the relevant law and building. When the auditor asks, you have it.
- Stays current. When DOB publishes new rules or sub-cycle lists, the platform updates centrally and every customer benefits.
- Cost scales sub-linearly. Adding a building to a platform is a marginal cost; adding a building to a consulting engagement is a full new line item.
Where it breaks:
- Edge cases. A good rules engine handles 95% of buildings cleanly. The 5% with quirks — mixed-use with unusual occupancy mixes, partial landmarking, special zoning overlays — still need human judgment.
- Garbage in, garbage out. A platform with wrong building data gives wrong outputs. Owners who skip the setup phase or refuse to validate the auto-detected laws get a confidently wrong answer.
- Workflow change. The platform replaces the spreadsheet, which means the property manager has to actually use it. If the team won't change habits, the platform sits unused.
- Subscription cost. Real money, every month, even when nothing is happening. For a single-building owner, the math may not work.
- No substantive expertise. A platform tracks the FISP deadline. It does not perform the FISP inspection. You still need the QEWI.
The honest assessment: a platform is the right backbone for a multi-building portfolio. It is overkill for a single owner-occupied small building. And it never replaces the substantive consultants — it complements them by maintaining the calendar and documentation around their work.
What about a property management company?
A managing agent provides some of the consultant value as part of their fee, particularly for routine filings (LL84 benchmarking, LL126 parapet observations, basic NOV responses). The good ones also use either a platform or a robust internal system.
The risk: management companies turn over staff, and the institutional memory walks out the door with the prior property manager. If your management company's compliance is "Susan keeps a spreadsheet," you are exposed when Susan changes jobs.
A decision framework
For owners deciding which way to go:
1 to 3 buildings, simple portfolio (e.g., a few small multifamily walk-ups): spreadsheet, augmented by a consultant or expediter for substantive filings. Total annual cost: a few thousand dollars in consulting fees plus the property manager's time.
4 to 20 buildings, mixed types: a software platform plus consultants for substantive work. The platform replaces the spreadsheet; the consultants handle the actual inspections and filings. Total cost: platform subscription plus consulting.
20+ buildings, complex portfolio: software platform is essential, plus a dedicated in-house compliance person and external consultants for specialized work. The portfolio is too big to track in any other way.
Special situations: A new acquisition with unknown history needs a one-time diligence engagement regardless of which model you use. An OATH-heavy year needs a violations-defense specialist. An LL97 Period 2 problem needs an energy professional. None of these are platform substitutes; they are jobs to be done.
The honest pitch for LLDesk is not "instead of a consultant." It's "the connective tissue that makes your consultants more effective and your team less dependent on a single property manager's memory." If a platform is selling you on replacing all human expertise, run.
Where I see owners go wrong
After two decades of conversations with owners, the failure patterns are consistent.
Sticking with the spreadsheet too long. The moment you have more than three buildings, the spreadsheet stops being the right tool. Most owners ride it to 10, then panic.
Outsourcing without oversight. Hiring a consultant and assuming they own everything. Then discovering at the next audit that the consultant filed the report but never told you about the deficiency findings.
Buying software and not configuring it. Signing up, importing buildings, and never actually validating the auto-detected laws or uploading the historical documents. Six months later, the platform is full of holes and the owner concludes "the software didn't work."
Treating compliance as a cost center. It is, in the sense of money out. But every dollar spent on calendar, alerts, and documentation is a fraction of the potential downside. A single missed FISP deadline can be $30,000 in late penalties. A single LL97 over-cap year can be six figures. The math always favors the disciplined approach.
Key takeaways
- Three approaches: spreadsheet, consultant, software platform. They are complements, not substitutes.
- Spreadsheets work for tiny portfolios with stable staff. They fail invisibly when staff turn over.
- Consultants provide substantive expertise — engineering, inspections, OATH defense — that no platform replaces.
- Software platforms are the right backbone for multi-building portfolios. They handle the calendar, alerts, and documentation; consultants handle the substantive work.
- The biggest mistake is treating compliance as a single-tool problem. Use the right tool for each job.
- Whichever combination you choose, be intentional. Default-mode spreadsheet management is the most expensive option of all.
