How Many Porta Potties Do You Need for a Wedding in Georgia?
The short answer
For a 150-guest, six-hour Georgia wedding with alcohol, Georgia's own planning table scaled to your guest count lands at roughly three units, including one accessible unit. Published wedding rules of thumb for the same event range from two to six, because they disagree with each other by a factor of three.

Compared across published planning guidance, 21 August 2026
What we found
Wedding restroom guidance disagrees by a factor of three, and none of it cites an authority. Georgia publishes one, but it starts above wedding scale.
Method: We compared the guest-per-unit ratios given in published wedding planning guidance on 21 August 2026, then computed the equivalent ratio from Ga. Comp. R. & Regs. 511-3-6 Appendix Table 2 with its own alcohol adjustment applied.
| Basis | Ratio | Units for 150 guests |
|---|---|---|
| Common planning ratio, lower bound | 1 per 75 guests | 2 |
| Common planning ratio, mid | 1 per 50 guests | 3 |
| Upscale-event ratio often quoted | 1 per 25 guests | 6 |
| Georgia Table 2, 500-person row at 6 hours | 7 units per 500 | roughly 2 |
| Georgia Table 2 with the 25% alcohol adjustment | 9 units per 500 | roughly 3 |
Georgia's own table, adjusted the way the rule tells you to adjust it, produces about one unit per 56 guests. That sits inside the common planning range and well under the one-per-25 figure some vendors quote, which is worth knowing before you are sold six units for a 150-person wedding.
Why does the advice vary so much?
Because there is no authority at wedding scale. Georgia's official table begins at 500 attendees, so for a typical wedding every source is extrapolating, and they extrapolate differently.
Ga. Comp. R. & Regs. 511-3-6 Appendix Table 2 is the closest thing Georgia has to a definitive answer, and its smallest row is 500 people. A 150-guest wedding sits well below the published range. That gap is why planning guidance fills the space with ratios rather than citations, and why those ratios do not agree.
The spread is not academic. At 150 guests, the difference between one per 75 and one per 25 is two units against six, which is roughly $480 of rental cost on Georgia pricing. Nobody publishing a ratio tells you where it came from.
The defensible approach is to scale from the table Georgia actually publishes, apply the adjustments the rule specifies, then add margin for the things a wedding does that a festival does not.
What does Georgia's table actually produce?
Seven units for 500 people at six hours, rising to nine once you apply the 25% alcohol adjustment. That works out to about one unit per 56 guests.
Read the table by peak crowd and hours at the event, then apply three adjustments the rule states in its own notes: subtract one unit for each sewered toilet already available on site, add 25% to the base number if alcoholic beverages are served, and round up to the next row for crowd sizes that fall between values.
The sewered-toilet credit matters more at weddings than anywhere else, because many Georgia wedding venues have permanent restrooms in a barn, house, or clubhouse. If the venue has two working sewered toilets, those come straight off the required portable count.
One structural note that changes multi-day planning: the table assumes units are serviced daily. For a single-evening reception that is not a constraint. For a weekend event with a Friday rehearsal dinner and a Sunday brunch, it is.
| Guests | Base from table | With alcohol | Practical order |
|---|---|---|---|
| 75 | 1 | 2 | 2 units, 1 accessible |
| 100 | 2 | 2 | 2 units, 1 accessible |
| 150 | 2 | 3 | 3 units, 1 accessible |
| 200 | 3 | 4 | 4 units, 1 accessible |
| 300 | 5 | 6 | 6 units, 1 accessible |
Scaled proportionally from the 500-person, six-hour row (7 units), with the rule's 25% alcohol adjustment applied and the result rounded up. Subtract one unit for each sewered toilet the venue already has.
Does a wedding count as a special event under Georgia rule?
Almost always. Georgia defines a special event as any temporary activity attracting more than fifty people who gather for more than two consecutive hours, and it makes no distinction between public and private.
Cross both thresholds and the rule applies, which most weddings do comfortably. The consequence that surprises couples is 511-3-6-.03(5): each special event sponsor using a portable sanitation unit must hold and show proof of a service contract with a certified portable sanitation company.
As the sponsor, that document is yours to hold. It is not the venue's and not the caterer's. In practice this is a non-issue when you book through a certified company, because the agreement is the proof, but it is worth knowing what the agreement is for.
Georgia also assigns responsibility for prohibited discharge and spillage to the property owner and the event sponsor jointly. If your venue is a private property owned by family, both parties named in that clause may be people at your wedding.
How many accessible units do you need?
At least one, and Georgia points to its accessibility code rather than fixing a ratio in the sanitation rule. Request it at booking, not later.
Georgia's table carries a note that units shall be provided in accordance with the Georgia Accessibility Code following state or local requirements. That is a pointer, not a number, so the count for your event is confirmed against the code and, where a permit is involved, the local permit office.
The practical rule at wedding scale is straightforward: order at least one accessible unit. A ground-level unit with a wide door and grab bars also serves elderly guests, guests using a walker, and anyone in a long dress, which at a wedding is a meaningful share of the room.
Accessible inventory across Georgia is thinner than standard inventory, so it is the first category to run out on peak Saturdays. Late requests come back unavailable rather than simply costing more.
What else changes the number at a wedding specifically?
Dwell time and drink service. Wedding guests stay put for the whole event in a way festival crowds do not, which concentrates usage rather than spreading it.
A festival crowd of 500 turns over through the day. A wedding of 150 is the same 150 people for six hours, all of them served drinks on a schedule and all of them queuing at the same moments, after the ceremony, before dinner, and after the toasts.
Two adjustments follow from that, and neither is in any table. Put the units where guests actually are rather than where the truck found it convenient, because a two-minute walk in heels is the difference between a used unit and an unused one. And if your bar service is generous, treat the 25% alcohol adjustment as a floor.
Georgia's placement rule pushes in the same direction. Units go as close as practical to the highest concentration of people, and as far from food service as possible. At a wedding those two instructions are in direct tension, and resolving it is a site-plan decision worth making deliberately rather than on the delivery morning.
What we would actually order
For 150 guests, six hours, alcohol, and no venue restrooms: three units, one of them accessible, plus a handwashing station near the catering area. Roughly $400 to $850 on Georgia pricing.
Frequently asked questions

Couples and wedding planners hosting an outdoor or venue-adjacent reception in Georgia.
Call (470) 431-3553How many porta potties do I need for 100 wedding guests?
Two units for a six-hour reception with alcohol, one of which should be accessible. That comes from scaling Georgia's Appendix Table 2 and applying its 25% alcohol adjustment. Subtract from that count if the venue has working sewered toilets, and add one if your bar service is heavy or the reception runs past six hours.
Do I need a permit for porta potties at my Georgia wedding?
Not usually a personal permit, but two obligations apply. The hauling company must hold a current Waste Removal and Disposal Permit, and as event sponsor you must be able to show proof of a service contract with a certified portable sanitation company. Venues on public land or in the right-of-way may also need a local event permit.
Should I get a restroom trailer instead for a wedding?
A trailer buys guest experience rather than capacity. For most Georgia weddings between 100 and 300 guests, one trailer near the reception plus standard units at the edges of the site delivers the best result per dollar. Below about 100 guests, deluxe flushing units often make more sense than a trailer that cannot reach the site.
How far in advance should I book wedding restrooms in Georgia?
Four to eight weeks for standard units, and longer for restroom trailers and accessible units on peak spring and fall Saturdays. Metro Atlanta and Savannah commit their trailer inventory earliest. Standard units are far more forgiving, with one to three business days typical outside peak weekends.
Where should porta potties be placed at a wedding?
Close enough that guests will actually walk to them, screened from sightlines, away from the food service area, and on ground a service truck can reach. Georgia rule requires units at a special event stay accessible for maintenance by truck at all times, so check the service route against the finished layout rather than the empty field.
