What does Frisco require for porta potties on building sites?
Frisco requires 1 sanitation facility per 5 building sites, no more than 200 feet walking distance between facilities. Facilities must be on site at the start of construction and must be serviced. The rule appears in the City of Frisco Residential Inspection Checklist, revised in February 2026.

How do I count units for a street of lots?
Divide the number of active building sites by 5 and round up, then check spacing. 12 lots ÷ 5 = 2.4, so you need at least 3 units. Then make sure no lot is more than 200 feet walking distance from a unit. On a long street, spacing can require more units than the division alone.
| Active lots | Lots ÷ 5 | Minimum units | Spacing check |
|---|---|---|---|
| 4 | 0.8 | 1 | All lots within 200 ft? |
| 9 | 1.8 | 2 | Place at ends of the run |
| 12 | 2.4 | 3 | Every 4 lots on a straight street |
| 23 | 4.6 | 5 | Map it — corners add walking distance |
How does this rule compare with OSHA?
OSHA 29 CFR 1926.51 counts toilets by crew size, while Frisco counts them by building sites. Builders must meet both. A framing crew of 25 on one lot needs 1 seat and 1 urinal under OSHA, and that lot still counts toward Frisco's 1-per-5 rule. Use whichever count is higher.
Use the crew calculator for the OSHA side.
How do I pass the inspection?
Pass the sanitation check by having units on site before the first activity, keeping them within 200 feet, and keeping service records. Dennis Rental Works logs every weekly service visit with a date and time. Keep units off the street and sidewalk, and stake them on open lots.

How many porta potties does my crew need under OSHA?
OSHA 29 CFR 1926.51(c) Table D-1 sets the minimum. 20 or fewer workers need 1 toilet. 20 or more workers need 1 toilet seat and 1 urinal per 40 workers. 200 or more need 1 seat and 1 urinal per 50. Check your contract and permit for stricter rules.
Can the porta potty go on the street or sidewalk in Frisco?
Keep it on private property. Units on a Frisco sidewalk, street or alley can block access and draw a code complaint. If private property is not possible, ask the City of Frisco about right-of-way use before delivery.
Can you stake the unit down so it does not blow over?
Yes. Dennis Rental Works can stake or strap units on open jobsites and windy lots at no charge when requested. North Texas spring storms can bring strong gusts, so anchoring is a good idea on bare lots from March through June.
Can you do a better price for a long rental or several units?
Yes. Dennis Rental Works discounts multi-unit orders and jobs expected to run three or more 28-day cycles. Builders with several lots in one Frisco subdivision can bundle units onto one route and one invoice. Ask for the multi-unit rate when you call.
