For a complaint on movable encroachment, the show-cause or removal notice gives the occupier:

For a complaint concerning a movable encroachment, the show-cause or removal notice typically grants the occupier 3 days to comply. This timeframe is considered reasonable for the removal of items that are not permanently affixed, allowing the occupier sufficient opportunity to rectify the situation before further enforcement action is taken.

• 24 hours is generally too short for a formal notice, unless it's an immediate and severe hazard.
• 7 days is often allocated for more significant or semi-permanent encroachments, or for issues requiring more complex resolution.
• 15 days is usually reserved for more complex cases, immovable encroachments, or for appeal periods, not for initial removal notices of movable items.
