Electrical Systems That Are Never Maintained Are Systems That Fail Unexpectedly.
NFPA 70B-Aligned Preventive Maintenance.

An annual preventive maintenance visit is a hands-on service visit, not just a quick look. A typical NFPA 70B-aligned visit includes: systematic visual inspection of main service, panels, disconnects, transformers, and accessible wiring for overheating, corrosion, water intrusion, physical damage, and code issues; thermal imaging of energized equipment to find hot spots from loose connections, overloads, or failing components; mechanical and electrical checks including tightening accessible terminations to manufacturer torque specs, verifying breaker operation, testing GFCI and AFCI devices, and sampling voltage and current to confirm proper loading; cleaning and minor servicing including removing dust and debris from panels and gear, checking ventilation and clearances; and documentation and reporting including updated panel schedules, logged inspection results, and a written report with findings and recommendations. Cali Rollin Electric includes the written service report with every visit. Minor remediation found during the visit can be quoted and completed same day when possible.

Not every small commercial building has a specific statute mandating NFPA 70B compliance, but for most commercial and industrial properties the answer is effectively yes. The 2023 edition of NFPA 70B converted from a recommended practice into a formal consensus standard with mandatory shall requirements for electrical maintenance programs where adopted by an authority having jurisdiction. OSHA requires that electrical equipment be maintained in a safe condition, and regulators and courts increasingly look to NFPA 70B as the benchmark for what safe condition means — meaning OSHA can reference it when evaluating electrical hazards under the General Duty Clause. Many insurers now explicitly require NFPA 70B-style preventive maintenance and documentation as a condition of coverage or favorable premiums for commercial accounts. While California does not send inspectors to every strip mall demanding an EMP, larger, more complex, or higher-risk commercial properties are now expected to have NFPA-aligned preventive maintenance in place.

NFPA 70B establishes a clear baseline. At least once per year: visual and functional inspection of all major electrical equipment and infrared thermography of panels, switchgear, MCCs, and other critical gear under normal load. Every six months: IR scans and checks on equipment in poor condition or with high criticality — Condition 3 under NFPA 70B. Every three to five years or per manufacturer: deeper maintenance including breaker and relay testing, insulation resistance tests, cleaning of switchgear interiors, and updated system studies covering short-circuit analysis, coordination, and arc flash. Cali Rollin Electric preventive maintenance plans start at $500–$900 per year for residential and $900–$1,800 per year for small commercial suites on an annual schedule, and $800–$1,400 per year for residential and $1,500–$3,000 per year for commercial on a semi-annual schedule.

Think of them as check versus fix. A safety inspection is primarily an assessment — a mostly visual and non-invasive check to see if equipment appears safe and compliant at a point in time. It focuses on finding obvious hazards, damage, or code issues and ends with a written report and recommendations. Preventive maintenance is a program of scheduled work that includes inspection plus specific maintenance actions — tightening, cleaning, adjusting, testing, replacing wear components, and updating documentation — designed to prevent failures and extend equipment life. An inspection tells you what is wrong or at risk. Preventive maintenance actually does something about it on a planned schedule. Cali Rollin Electric offers both standalone safety inspections and ongoing preventive maintenance programs — the right choice depends on your property type, risk profile, and whether you need a one-time assessment or long-term documented maintenance.

Yes. A preventive maintenance program makes just as much sense for rental properties as for owner-occupied or commercial buildings, especially where you have older wiring or panels, multiple tenants including duplexes, fourplexes, or small multi-family, or heavy electric loads like EV chargers, electric heat, or older HVAC. A right-sized rental PM program typically includes annually: panel inspection and tightening, GFCI and AFCI testing, IR scan of panels, and safety walk of common area lighting and receptacles. At tenant turnover: a quick safety check in the unit covering outlet tests, obvious damage or DIY wiring, and smoke and CO alarm verification. Every three to five years: deeper check of service capacity, grounding and bonding, and any known legacy issues like FPE, Zinsco, knob and tube, or aluminum wiring. This documented program aligns with NFPA 70B expectations and helps satisfy insurer and lender questions about how you manage electrical risk in your portfolio.

NFPA 70B treats deficiencies as part of a closed-loop process: find, assess, correct, verify, and document. The technician documents what is wrong — an overheated lug, overloaded circuit, deteriorated insulation, or code violation — and assigns a severity and priority level from monitor to schedule repair to immediate action required if there is fire or shock risk. For critical issues, temporary safeguards like de-energizing a circuit or reducing load may be implemented immediately. Specific corrective actions are recommended: tightening or reterminating conductors, redistributing load, replacing breakers or damaged components, or correcting code violations. Many minor deficiencies can be corrected on the same visit if authorized. Larger items are quoted, scheduled, and when required performed under permit. After repairs the affected equipment is re-checked visually, mechanically, or with IR as appropriate to confirm the issue is resolved. The maintenance records are updated so you can demonstrate that the deficiency was addressed — which is exactly what NFPA 70B requires and what insurers and safety auditors want to see.
