If you own or manage a building with rooftop fall protection systems, you are responsible for making sure those systems meet federal safety standards. The rules are not optional, and the consequences of ignoring them are real: fines, lawsuits, and the possibility that someone gets hurt because an anchor was not properly maintained.
This guide breaks down the key OSHA and ANSI requirements that apply to roof anchor systems in 2026, written in plain language for property managers and building owners who need to understand what is required and why.
The Two Standards That Matter
OSHA 1910.27(b)(1) (Rope Descent Systems)
This is the standard that most directly affects building owners. Under OSHA 1910.27(b)(1), before any worker uses a rope descent system (which includes window cleaners, facade inspectors, and maintenance crews using rope access), the building owner must provide written confirmation that:
- Each anchorage has been identified
- Each anchorage has been tested and certified
- Each anchorage is maintained in accordance with manufacturer specifications
- Each anchorage can support at least 5,000 pounds per attached worker
This is not a suggestion. It is a legal requirement, and the building owner is the responsible party. If a window cleaning company shows up and asks for anchor certifications and you cannot produce them, work stops until you can.
ANSI Z359.18 (Anchorage Connector Standards)
ANSI Z359.18 fills in the technical details that OSHA leaves to industry standards. It defines what a "competent person" must evaluate during an inspection, how load testing should be performed, and what documentation must be maintained. While ANSI standards are not law by themselves, OSHA references them as the accepted benchmark for compliance, and courts treat them as the standard of care.
What Inspections Are Required?
Annual Visual Inspection
Every roof anchor system must be inspected at least once per year by a competent person. "Competent person" has a specific legal meaning under OSHA: someone who can identify existing and potential hazards and has the authority to take corrective action.
The annual inspection includes evaluation of each anchor point for corrosion, cracks, deformation, loose fasteners, and damage to the surrounding substrate. Each anchor should be individually identified with a tag or marking, and the inspection results must be documented in a written report.
5-Year Load Testing
Under ANSI/IWCA I-14.1, standard industry practice is to proof-load test anchors installed with adhesive bolts (as opposed to mechanical anchors or welded connections) every 5 years. This is a recommended practice under the industry standard rather than a separate OSHA mandate, but it is the benchmark that inspectors and engineers apply. This test applies a controlled force to the anchor, typically 5,000 pounds for personal fall arrest anchors, to verify it can handle the required load without deformation or failure.
Load testing requires specialized hydraulic equipment and should be performed by a company that regularly performs this service. The results are documented with load measurements and before-and-after photographs of each anchor. Learn more about our load testing and recertification services.
10-Year Recertification
Every 10 years, anchor systems that support rope descent work require a comprehensive engineering evaluation under OSHA 1910.27(b)(1) that goes beyond annual inspection. Recertification typically includes:
- Review of original design documents and previous inspection history
- Structural assessment by a licensed professional engineer
- Load testing of all anchor points
- An engineer-stamped certification report
This is the most thorough evaluation your anchor system will undergo, and the resulting certification report becomes your building's official compliance record for the next certification cycle.
State-Specific Variations
While federal OSHA sets the baseline, several states have their own OSHA plans with additional requirements:
- California (Cal-OSHA) requires fall protection systems on all buildings three stories and above, a stricter threshold than federal standards
- Hawaii (HIOSH) adopts federal standards with state-specific enforcement under Hawaii Administrative Rules Chapter 12-60
- Alaska (AKOSH) runs its own enforcement program with additional cold-climate considerations
- Oregon (Oregon OSHA) mirrors federal standards with state-level enforcement priorities
- Washington, Nevada, Arizona, and most other Western states follow federal OSHA directly
What Happens If You Are Not Compliant?
OSHA penalties for fall protection violations are among the highest in workplace safety:
- Serious violations: Up to $16,131 per violation
- Willful or repeated violations: Up to $161,323 per violation
- Failure to abate: Up to $16,131 per day
Beyond fines, building owners face civil liability if a worker is injured using an uninspected or non-compliant anchor system. Insurance carriers increasingly require documented anchor maintenance records, and gaps in documentation can affect coverage when you need it most.
Getting Started
If you are not sure where your building stands, the best first step is a professional evaluation. ADS provides free initial assessments across the Western US. We will review your current documentation, inspect your anchor system, and give you a clear picture of what is needed to bring your building into full compliance.
