Steps
Confirm the local sign ordinance's definition of exempt routine maintenance (commonly like-for-like bulb/lamp replacement, cleaning, and minor repair) versus work that requires a new permit
Check whether changing illumination technology (e.g., converting fluorescent or neon to an LED retrofit) is treated as routine maintenance or as a sign alteration requiring a permit in that jurisdiction — this is commonly treated as more than routine maintenance because it changes the listed electrical components
Confirm whether any structural change (new cabinet, new mounting, size or copy change) is involved, since these virtually always require a new permit even if framed as 'maintenance'
If the sign is a legally nonconforming structure, confirm what level of alteration the local ordinance allows without triggering loss of nonconforming status or a new permit review
When in doubt, confirm directly with the local building/sign department before performing work, since the maintenance/permit line is set locally and enforcement varies
Known gotchas
Retrofitting illumination technology (e.g., neon or fluorescent to LED) is often not treated as routine maintenance because it changes listed electrical components — verify locally before assuming a 'like-for-like' exemption applies
What counts as 'routine maintenance' is defined locally and not standardized — never assume a specific threshold (dollar value, percentage of sign value, or specific scope) without checking the local ordinance text
Work on a legally nonconforming sign carries extra risk: an alteration that would be routine on a conforming sign can jeopardize nonconforming status if it exceeds the local ordinance's allowance
