Small office/shop changes — do minor works still need approval, or only full fit-outs?

Short answer: don't assume "small = no permission" — in a commercial building, even minor works usually need at least the BUILDING/landlord's approval (a fit-out or works NOC and often insurance/method statements), and anything touching MEP, fire, structure, the façade or external signage typically needs an authority permit too, however small it looks. The rough line: purely cosmetic, non-fixed, within-your-unit changes (paint, loose furniture) are usually fine; but a partition (fire/means-of-escape), electrical/lighting changes (MEP), anything affecting fire systems, structure, the shopfront or external signage crosses into permit territory. Skipping it risks fines, being made to undo the work, insurance/liability problems, and trouble at licence renewal or handover — so check first, per unit and per building.

The rough line (minor vs permit-needed): - Usually fine without a permit (still check your lease/building): paint, loose/free-standing furniture, purely cosmetic changes that don't touch services, fire, structure or the exterior. - Usually needs approval even if "small": - Partitions/layout — affects fire compartmentation and means of escape, so almost always controlled. - Electrical/lighting/MEP changes — touching power, data, HVAC, plumbing = permit/qualified-contractor territory. - Fire systems (sprinklers, alarms, detection) — always controlled; never touch without approval. - Structure — any structural change. - Shopfront / external signage / façade — typically needs authority + building/landlord sign-off.

The building's role (don't skip this): - Most commercial buildings require a fit-out/works NOC from the landlord/management even for minor works — plus approved contractors, insurance, sometimes method statements and works hours. This is separate from, and additional to, any government permit.

If you skip it: - Fines, stop-work, or being ordered to reinstate; insurance/liability exposure if something goes wrong; and problems at trade-licence renewal, inspections or lease handover where unpermitted works surface. The saving is never worth it.

Common mistake: treating a partition, a lighting change or new signage as "too small to bother" — those are exactly the ones that touch fire, MEP or the façade and need sign-off. Check the requirement per your unit and building first; a fit-out and finishing contractor who works in commercial buildings will know what needs a permit/NOC and handle the approvals. What "minor" job caught someone out on approvals?
