Two Different Businesses That Both Do Inspections
Specialist compliance firms and multi-service engineering firms both perform building inspections, and both can file with DOB or state authorities. But they are structured as different businesses, with different cost bases, different staffing models, and different definitions of success. Understanding the difference is how owners avoid paying engineering-firm rates for inspection-firm work.
Specialist Compliance Firm
Built around inspection, testing, certification, and filing. The actual report is the deliverable, and the business model is per-inspection rather than per-hour. Staff are licensed inspectors, Master Plumbers, QEWI engineers, and similar specialty credentials.
- Primary product: The inspection and its filed record
- Billing model: Flat fee per inspection or annual contract
- Staffing: Inspectors, certified specialists, filing administrators
- Examples of scope: Annual boiler inspections, Cat 1 / Cat 5 elevator inspections, LL11 facade examinations, LL84/87/97 benchmarking, LL152 gas inspections, backflow testing
- Turnaround: Same-day to one-week scheduling typical, filings within 24 hours of inspection
Multi-Service Engineering Firm
Built around engineering studies, design, capital planning, and restoration. Inspections are usually one offering inside a much larger book of services. Staff includes PEs, RAs, structural engineers, MEP engineers, plus inspectors.
- Primary product: Engineering studies, capital plans, design documents, restoration scoping
- Billing model: Hourly or project-based, with hourly rates reflecting the engineering work the firm primarily sells
- Staffing: Licensed PEs, RAs, MEP engineers, structural specialists, with inspector roles often filled by junior or rotating staff
- Examples of scope: Facade restoration design, capital improvement plans, retro-commissioning, energy upgrade design, structural condition assessments, full building MEP studies, plus inspections as part of any of these scopes
- Turnaround: Weeks to months for typical engineering work; inspections fit into project schedules rather than driving them
Both types of firm have legitimate roles in building compliance. The mistake owners make is hiring one type when the other would have been faster, cheaper, or more appropriate for the actual work needed.
