Construction site portable toilets are the units a contractor places on a job for its crew, sized by the number of employees under California's own construction standard. Title 8 Section 1526 governs California job sites rather than the federal rule, and it allows non-water toilets where water closets are not feasible, subject to local rules. A local provider places, services and removes the units.
A construction crew in San Francisco needs a toilet on the first day of the job, not the fifth. Whether the work is a kitchen in a Victorian flat, a multi-unit retrofit or a commercial shell, the crew needs a place to go, and the rule that sets how many places is California's, not the federal one.
The governing rule is California Code of Regulations, Title 8, Section 1526, Toilets at Construction Jobsites. Subsection (a) requires one separate toilet facility for each 20 employees or fraction thereof, of each sex, and the number of toilets must be at least half the minimum required number of facilities. Where fewer than five employees are on the site, one single-user toilet designated for all-gender use is sufficient. Cal/OSHA, the Division of Occupational Safety and Health within the California Department of Industrial Relations, is the body that applies the state standard.
Portable units come into the picture under subsection (c), which allows non-water disposal, such as chemical or recirculating toilets, where water closets are not feasible, subject to local rules. That is why many San Francisco job sites without a sewer or water connection rely on portable units. Temporary field conditions must still have at least one toilet available, and mobile crews with ready transportation to nearby toilets are excepted. The sections below cover the count, what changes it and how units are placed on a city site.
Do not connect units to a water line or drain their holding tanks onto the site; the provider handles waste under its own registrations and permits. Do not let the unit count fall below the crew's need when the headcount changes; tell the provider when the crew grows. Do not place a unit in the path of hoists, trenches or traffic, and keep it clear of the work zone. If a unit is damaged or tips, stop using it and call the provider.
The first step is the number of employees on the site. Section 1526 sets separate facilities for each 20 employees or fraction thereof, of each sex, so twenty-one workers of one sex call for two separate facilities. Where fewer than five employees are on the site, one single-user unit designated for all-gender use is sufficient. The technician works from the headcount the contractor provides.
The technician confirms whether the site has a sewer connection or a water supply that could serve flushing toilets. Where water closets are not feasible, the subsection allowing chemical or recirculating units applies, subject to local rules that the provider and contractor check together. That answer settles whether the site is served by portable units or by fixed facilities.
The units are placed on firm, level ground near the work, with a clear path from the work area. Toilets and urinals can both count toward the total, but at least half of the required facilities must be toilets. The technician places the units so no worker has to cross the work zone to reach them.
Temporary field conditions call for at least one toilet to be available at all times. Early in a job, before the crew is full, the provider can start with the minimum and add units as headcount grows. The schedule for adding units is set with the contractor, so the count keeps pace with the crew.
The units are serviced on a schedule that matches the crew's use, and the waste is removed by the provider under its own registrations and permits. At the end of the job the units are removed and the site is left clear of them. The contractor confirms the final headcount so the last visits match the work.
One separate facility for each 20 employees or fraction thereof, of each sex, with at least half of the required facilities being toilets.
Title 8 Section 1526(a) is the rule, and it counts the employees on the site. A site with fewer than five employees may use one single-user toilet designated for all-gender use. The federal tiered table does not apply on a California job site and should not be used to size one.
Where the count is in doubt, the contractor confirms the headcount with the provider before the units are set. The count is based on the employees actually on the site, not on a schedule of planned workers.
Yes. Where a sewer or water connection is not feasible, Section 1526 allows non-water disposal such as chemical or recirculating toilets, subject to local rules.
That is the subsection that puts portable units on many San Francisco sites without a connection. The provider confirms the local rules for the site before placing units, and the contractor keeps the site consistent with them.
Where a sewer or water connection is available and suitable, the rule for water closets applies, and portable units are not the default.
Mobile crews with ready transportation to nearby toilets are excepted under subsection (e).
A crew that moves between sites and can reach toilets nearby without delay may not need units at each site. The exception turns on transport and nearby toilets, not on convenience. A crew that stays on one site for the day, or whose nearby toilets are not close, needs units placed on that site.
The provider can advise on whether a short task qualifies, but the test is the crew's access to toilets, and the contractor confirms it.
Temporary field conditions must have at least one toilet available from the start.
Subsection (b) requires at least one toilet to be available under temporary field conditions. A job that starts with a few workers and a shell still to build can begin with a single unit and add more as the headcount grows. The count is revisited as the crew changes.
The provider sets the first unit before the crew arrives, so the crew is not waiting for a full bank to be sized.
The number of employees, the length of the job, the service visits and the access to the site set the quote. The provider explains the price, and it is approved before work starts.
The count of units follows the crew, and the crew changes as the job moves from demolition to framing to finish work. A larger crew needs more units and more visits, and a long job needs its units maintained across many months. The number of units also sets how many service visits the site needs.
Access matters as well. A unit placed on a hill, behind a gate, up stairs or in a rear yard takes more time to set and to service, and the quote reflects that. Any street space permit is pulled by the contractor, and the price is confirmed before delivery.
A small site with a crew of a few people is served by a small number of single units, often one all-gender unit for a crew under five. As the crew grows, the count moves up under the 20-employee ratio. The units are placed where the crew works and kept clear of the material staging area.
A larger crew with more than one sex needs separate facilities for each sex, so the bank is counted as separate groups. The ratio applies to each group. All-gender single-user units can count toward the total under conditions the regulation lists, and the contractor confirms those conditions before the bank is set.
A retrofit on an occupied building, such as a soft-story job, often keeps a crew working inside and out for months. The units may sit on the street or a driveway, which brings the public right of way rules into play. The provider plans the placement with the permit footprint, and the contractor pulls the permit.
A commercial shell or a multi-phase site can run for seasons, and the units move as phases change. Each phase needs the count re-checked against the crew on site, and each move is a new placement. The provider keeps the units serviced through every phase and confirms the count before each move.
San Francisco construction sites are heavy on hill lots, narrow frontages and occupied buildings.
Earthquake retrofits keep crews on occupied buildings for months. The Mandatory Soft Story Program covers wood-frame buildings with five or more residential units and two or more stories over a soft or weak story, permitted for construction before January 1, 1978. The city's Department of Building Inspection counted at least 2,800 buildings with a soft-story condition, which is the scale of work this rule creates.
Weather matters on open sites. A wet winter turns bare ground into mud around a unit, and a dry summer brings dust. Pacific wind is strongest on the west side of the city and at the coast in summer, so units on open ground are staked or weighted and checked after windy spells.

California job sites are governed by Cal/OSHA Title 8 Section 1526, not by a federal summary.
Portable toilet waste leaves a site under a chain of registrations and permits.
No. California is a state-plan state, and its construction toilet rule is Title 8 Section 1526, applied by Cal/OSHA. The federal tiered table is not the California requirement and should not be used to size a California site. A contractor who plans to the state rule meets the state count, and the provider sets the units to those figures.
Single-user units designated for all-gender use can count toward the required facilities where the conditions in Section 1526(a)(2) are met. Those conditions include the rule that multi-user facilities are split equally by sex. The contractor confirms the conditions with the provider before the units are placed, and the provider can set single-user units for a small crew.
The rule allows non-water disposal only where water closets are not feasible, subject to local rules. A site with a sewer connection that can take a water closet is planned on that basis, and the provider does not assume a portable unit is the answer. The contractor confirms with the city which arrangement applies.
Any business that cleans chemical toilets or disposes of the cleanings must register under California Health and Safety Code Section 117405, and the registration is valid for one calendar year. The provider holds the registrations and the permits for hauling and disposal. The contractor's job is to confirm that the provider holds them.
The service schedule is set in the quote and follows the crew's use. A large crew needs more visits, and hot weather or wet ground can change the schedule. The provider confirms the schedule before delivery, and the contractor reports changes in headcount so the service follows the crew.
Tell the provider as soon as the headcount changes. The count is worked again under the same ratio, and a unit or a bank is added where needed. The provider can add units before the crew arrives, so the site does not fall below the count during a busy week.
