How Many Guards Does Your Property Need?

Count your entries, multiply by shifts per day, add reliever cover. One gate covered round the clock needs three 8-hour shifts plus a reliever for weekly offs — roughly four guards on roster, not one. A two-gate society on 12-hour day cover needs about four to five. The exact number is fixed after a site survey, but this entries-times-shifts method gets you within one of the right answer. Try /tools/guard-requirement-calculator for a quick estimate.

Guard headcount follows posts, not square feet. Walk your site and list every position needing a human: main gate, rear gates, basement entries, reception floors, parking stretches, night boundary. A sprawling single-entry farmhouse needs fewer guards than a compact three-gate commercial plot. Each post is one guard per shift — that is the unit everything else multiplies.

Eight-hour single-shift cover needs one guard per post. Twelve-hour day cover needs two. Round-the-clock cover needs three 8-hour shifts per post. Event and function cover is counted in event-shifts instead — a wedding needs a team for the function window plus setup and dispersal, sized from guest count and venue layout rather than daily shifts. See /services/event-security for function-wise sizing.

Guards take weekly offs and leave. Without relievers, your gate goes unmanned or a tired guard doubles up — both are how incidents happen. As a rule, rosters of four or more need at least one reliever; larger rosters need proportional cover. Reliever cost is a fraction of one incident's cost. Any quote without a reliever line should be questioned before signing.

Property | Posts | Cover | Indicative roster Independent home | 1 gate | 12-hr night or 24-hr | 2–4 guards Small apartment block | 1–2 gates | 12–24 hrs | 3–6 guards Mid-size society | 2–4 gates + patrols | 24 hrs | 8–14 guards Office / showroom | 1–2 posts | 10–12 hrs | 2–4 guards Factory / warehouse | 2–4 gates + night | 24 hrs | 8–14 guards Event (500 guests) | Entries + parking | Function window | 8–14 hands These are planning bands, not quotes — the survey fixes the final number. Contract deployment models are covered under /services/manpower-services.

Single-home posts can run on supervisor visits. Multi-gate societies, factories and campuses need denser supervision — scheduled audits, register checks and night visits. Supervision is planned separately from guard headcount and listed as its own line in a proper quote. If a vendor bundles it invisibly, ask for the visit schedule in writing.

Example one: a two-gate society with 24-hour cover. Two posts times three shifts equals six, plus one reliever and one night-patrol augmentation — plan seven to eight on roster. Example two: a single showroom open twelve hours. One post times two shifts equals two, with reliever cover shared from the zone pool — plan two to three. Example three: a factory with a material gate, a labour gate and night boundary watch. Three posts times blended shifts plus a reliever — plan eight to ten. Notice the pattern: posts first, shifts second, relievers always.

Mistake one: hiring one guard for 24/7 cover and calling it done — that is one shift covered and two empty. Mistake two: counting plot size instead of posts, which understaffs multi-gate sites. Mistake three: skipping relievers to save money, which buys absenteeism instead. Mistake four: forgetting supervision — ten unsupervised guards perform worse than six supervised ones. Mistake five: sizing from a phone description instead of a walkthrough; staircases, basements and rear gates never appear in phone estimates.

The method above gives you a planning number; the written quote makes it contractual. A proper quote names every post, its shift pattern, the reliever arrangement, the supervisor's visit schedule and the start date — each line checkable. When comparing vendors, normalize their quotes to this format before comparing prices; a cheaper total with fewer named posts is not cheaper, it is thinner. Sign only the quote whose posts you could walk and verify, because that is exactly what supervision will do every month.

One: headcount equals posts times shifts plus relievers. Two: one 24/7 gate means about four guards on roster. Three: never accept a quote without a reliever line. Four: use the calculator for a starting number, then confirm with a free site survey and a written post-wise quote.
