8.3 Re-Occupancy Criteria, Occupant Notice, and Access Control

The work area is closed until clearance — not until the crew's trucks leave

Quick Answer: Occupants do not re-occupy the work area until post-abatement procedures in 40 CFR 745.227(e)(8) succeed: a visual inspection showing no remaining deteriorated paint and no visible dust, debris, or residue, then dust sampling by a certified inspector or risk assessor (not the supervisor), with results below the action levels. On or after January 12, 2026, those action levels are 5 µg/ft² floors, 40 µg/ft² interior window sills, and 100 µg/ft² window troughs. Exterior work is a visual standard, including the outdoor living area closest to the abated surface and paint chips at the dripline or foundation.

HUD Guidelines Chapter 8 states the same operational rule: do not allow residents to reoccupy the work area until a clearance examination (or cleaning verification, where that RRP concept applies) has been passed; if clearance is not achieved at day's end, keep the barriers in place overnight and instruct residents not to enter. For abatement under Subpart L, cleaning verification is the wrong tool. Abatement of interiors that require dust sampling ends only below the action levels, sampled by the independent discipline.

Re-occupancy of the work area is not the same as re-occupancy of the building. Occupants who stayed in the kitchen under a valid isolation plan still cannot open the zipper into the contained bedroom until that bedroom has passed (e)(8). Occupants who were fully relocated do not move back into a unit that is the work area until that unit has passed. The OPP must use that vocabulary so a property manager does not treat crew demobilization as a welcome-home date.

Interior sequence the OPP should promise — and the supervisor cannot shortcut

40 CFR 745.227(e)(8) is blunt: the following post-abatement procedures shall be performed only by a certified inspector or risk assessor. The supervisor who wrote the OPP, ran prep, and ran cleanup does not wipe the floors, bag the wipes, and declare the unit cleared. Sampling locations, the 1-hour wait after final cleanup, multi-family random sampling, and the 2026 dust-lead hazard statement are Chapter 18. This section only needs the occupant-protection consequence.

A passing visual without dust results is not re-occupancy of an interior work area that required sampling. A supervisor's wet-wipe of a windowsill is not a clearance sample. A same-day verbal it's clean from the crew is how children get into a dusty room before the lab calls.

Worked example — isolation, waiting on the lab. Apt. 2's bedroom is contained. Occupants have been living in the rest of the unit. Cleanup finishes Friday afternoon. The inspector's visual passes. Dust cassettes go to the lab. Results arrive Monday, all below 5/40/100. The work area may be opened Monday after the supervisor confirms the written results — not Friday night because the plastic looked clean. The OPP should have said that.

Worked example — failed floor. One floor sample is 12 µg/ft². The represented components are recleaned and retested. Occupants do not get the bedroom back because three of four samples passed. Failed clearance is still a closed work area.

Exterior re-occupancy of the outdoor living area

Following exterior paint abatement, 745.227(e)(8)(v)(C) is a visual protocol, not a dust-wipe protocol for siding:

• A visual inspection is conducted.
• All horizontal surfaces in the outdoor living area closest to the abated surface shall be found to be cleaned of visible dust and debris.
• A visual inspection shall determine whether paint chips are present on the dripline or next to the foundation below any exterior surface abated. If paint chips, dust, or debris are present, they must be removed from the site and properly disposed of.

The OPP for an occupied exterior job should say that porches, stoops, play areas, and walkways in that closest outdoor living area stay closed to occupants until that visual standard is met, and that children do not play at the dripline while chips are still on the soil. Interior rooms can often remain occupied during exterior work if openings are sealed — that is a Section 8.2 isolation choice — but the work area still includes the ground and horizontal surfaces the regulation names.

Who tells occupants they may return

745.227 does not designate a public-affairs officer. HUD Guidelines Chapter 8 recommends that the property owner or manager notify residents of what lead-based paint hazards were controlled and of the clearance (or cleaning verification) results — and recommends that notification whether or not the work is federally assisted. For work that is not federally assisted, HUD notes that at least the person who ordered the work must be informed of the results. The building owner also receives copies of reports and plans under 745.227(i).

The supervisor's duty in the OPP is to name the communication procedure so re-occupancy is not a crew-level improvisation:

The supervisor does not have to knock on every door personally. The supervisor does have to refuse to drop barriers because a tenant is tired of the hotel. Sending people back before (e)(8) is a work-practice failure, an OPP failure, and a way to undo the cleanup the supervisor was required to be onsite for.

Belongings, after-hours access, and pets

Access control is what makes isolation real at 2 a.m., not only while the crew is watching. The OPP must say the controls. How to tape 6-mil and size a decontamination unit is Chapter 10.

Belongings. Occupant belongings that would be contaminated do not stay in the work area as-is. Move them to a safe area outside containment, or cover them with an impermeable covering with all seams and edges taped (the same practical rule HUD writes at 24 CFR 35.1345(a)(3) for HUD-assisted hazard reduction). A contained closet the tenant will open tonight for a coat is still the work area. The plan should say whether furniture is moved, wrapped, or both, and that unwrapping waits for clearance of that room.

After-hours access. Barriers stay up overnight and on weekends. Occupants who remain in the dwelling are instructed — in the plan and in the notice — not to enter the work area to grab belongings, inspect progress, or let the dog in. A lockable barrier or an attended entry is a management procedure; a polite request is not. HUD Guidelines Chapter 8: if clearance has not been achieved at the end of the day, keep the barriers in place overnight.

Pets. Pets track dust on fur and paws, chew poly, and re-enter through any gap a toddler can find. The OPP states whether pets are boarded, confined outside the work area, or otherwise kept out. A litter box in the contained spare room is an occupant-protection failure.

Warning signs, critical barriers, decon, HVAC. The plan names that warning signs will be posted at entries to the work area (and, on HUD-assisted jobs, 24 CFR 35.1345(b)(2) points to 29 CFR 1926.62(m) style signs, posted even without an OSHA over-PEL finding, in the occupants' primary language to the extent practicable). It names critical barriers at every occupant opening. It names the decontamination path so workers do not walk contamination through the occupied kitchen. It names HVAC isolation. Exact construction, negative-air calculations, and three-stage decon layout are Chapter 10. OSHA sign rules tied to the PEL are Chapter 16. Do not dump those chapters into the OPP paragraph — do make the OPP say they will exist and that occupants cannot bypass them.

Worked example — after-hours coat. Containment is up in the bedroom. The tenant still lives in the rest of the unit. Saturday the tenant texts the worker for permission to grab winter coats from the contained closet. The OPP's access-control section says no occupant entry until the inspector's passing results are in. The supervisor's answer is no, keep the barrier, we will stage a coat from a non-work closet or buy time another way. Opening the zipper for a coat is re-occupancy of the work area.

Worked example — multi-family visitors. Common-hall paint abatement. The OPP states visitors use the rear stair, signs are at both corridor doors, the front stair is the work area until exterior-adjacent floors and the hall pass visual and any required dust sampling, and delivery drivers are directed by the superintendent. A pizza carrier walking the dirty hall is an occupant the plan failed to manage.

Putting 8.1–8.3 together on the job

1. Write a unique OPP before start, as a certified supervisor or project designer (8.1).
2. Choose relocate or isolate; never put occupants in the work area; name how children under 6 and pregnant occupants are protected; relocate when there is no second living space (8.2).
3. Keep the work area closed until independent clearance below 5/40/100; tell occupants through the named notice; hold belongings, after-hours access, pets, signs, barriers, decon, and HVAC as management procedures (8.3).
4. Attach the OPP to the abatement report, keep it ≥3 years, and give the owner a copy.
