- In Campbell, CA, Public Works handles temporary right-of-way use through its encroachment permit process.
- For a park or campus setting, discuss the proposed pad and delivery route with the site contact responsible for the space.

Placement Permission for Private Lots and Public Space
Permission depends on the property boundary, the proposed use and the office responsible for the space. Choosing where to put a porta potty means considering the door, guest route and delivery access alongside that permission. Call while the location is still being discussed; approvals for placement can be addressed during planning.
The Standard Unit on Private Property
A standard unit can suit a remodel driveway, side yard or job-site lot when a firm, level pad leaves the work route open. Discuss the location with the owner or landlord. An HOA or property manager may also have conditions for shared space, appearance or access. A driveway apron may cross a public sidewalk or right-of-way, so ask the street-use office about the boundary rather than assuming every paved area belongs to the lot.
For temporary public right-of-way use in Campbell, CA, Public Works lists a miscellaneous-work encroachment permit category. Ask that department how the proposed unit location should be submitted.
The Accessible Unit at a Public Event
The accessible unit belongs on a usable approach from the gathering area, with space at the entrance. Include the approach and waiting area in the proposed event layout. The ADA Standards address accessible routes connecting accessible facilities and spaces on the same site. Discuss the applicable layout requirements with the event reviewer.
Street fair porta potty rental planning should identify the approved toilet area within the event layout. A closed street still needs room for pedestrians, neighboring entrances and designated vehicle access.
The Wash Station at a School or Park
A wash station fits beside the restroom approach at a school field or park picnic area when people can use it without blocking circulation. Ask the school facilities contact or parks reservation staff about the proposed location and delivery route.
In Campbell, CA, a picnic reservation is required to serve alcohol or bring an approved inflatable at eligible sites, according to Recreation & Community Services. Ask parks staff separately about bringing portable toilets and wash stations; the picnic reservation rule does not itself approve their placement.
The Trailer Restroom on a Paved Lot
A trailer restroom needs a site plan that accounts for the tow vehicle, tongue, steps and guest approach. A private campus lot or wedding venue's paved area is worth discussing with the facilities manager. Identify overhead lines, drains, equipment and vehicle movement when proposing the pad. Keep neighboring driveways and fire lanes open.

Use a firm, level pad separated from vehicle movement, equipment, drains and overhead lines. Keep everyone from shifting, tilting, hoisting or climbing onto a unit. Your delivery pro arranges service visits and handles requests to reposition equipment. One of our local porta potty partners discusses how access and placement affect the scope and price before the rental is arranged.
