Cal. Civ. Code § 460.175

(A) (1) Following inspection of a premises by a lead inspector, the following low-risk abate-
              ment and/or containment activities may be performed on the owner’s property by authorized
              persons:
                  (a) Applying encapsulants over suitable surfaces;
                  (b) Removing doors, cabinet doors, windows on hinges (such as wooden storms) and shutters
                  by disengaging hinge pins or removing hinges;
                  (c) Covering surfaces with approved coverings;
                  (d) Capping baseboards; and
                  (e) Removing cabinet drawers and shelves which are not glued, nailed or otherwise affixed
                  to supports.
              (2) Most low-risk abatement and containment activities may be performed before non-low-risk
              abatement work begins, or after such work is complete, including final clean-up. Replacement of
              doors must be completed before reoccupancy reinspection. Surfaces identified with loose lead-
              based paint, other coating, plaster or putty at initial inspection that will be contained with approved
              coverings must either be:
                  (a) completely covered prior to reoccupancy reinspection; or
                  (b) made intact by an authorized person prior to reoccupancy reinspection, in which case
                  covering may occur after reoccupancy reinspection.
              (3) Encapsulants may be applied only after a reoccupancy reinspection, or, if only low-risk
              abatement and containment activities will be performed, after all other low-risk abatement and
              containment work is completed.

           (B) (1) Following inspection of a premises by a lead inspector,
               the following moderate-risk abatement activities may be performed by authorized persons:
                   (a) Removing surfaces containing dangerous levels of lead, with the exception of walls and
                   ceilings, and provided such removal is not accomplished by demolition.
                   (b) Making small amounts of loose lead-based paint, other coating, plaster or putty intact, as
                   defined in the following manner:
                       1. Interior Rooms, Hallways or Common Areas. Making intact up to two square feet,
                       but no more, of loose lead-based paint, other coating, plaster or putty on surfaces that are
                       not moveable impact surfaces per room, hallway or common area. Any small areas of
                       loose lead-based paint, other coating, plaster or putty on such eligible surfaces, which the
                       inspector has not ruled out as being of greater dimension than two square feet, in
                       accordance with 105 CMR 460.730(C), must be measured by the authorized person who
                       wishes to make these areas intact. Such measurements shall be taken in accordance with
                       the procedure set out in instructional materials approved by the Director.

2. Exterior of Residential Premises, Including Any Other Structures Within the Same Lot
                      Line. Making intact up to 20 square feet, but no more, of exterior loose lead-based paint,
                      other coating, plaster or putty on surfaces that are not moveable impact surfaces. Any
                      areas of loose lead-based paint, other coating, plaster or putty on such eligible surfaces,
                      which the inspector has not ruled out as being of greater dimension than 20 square feet, in
                      accordance with 105 CMR 460.730(C), must be measured by the authorized person who
                      wishes to make these areas intact. Such measurements shall be taken in accordance with
                      the procedure set out in instructional materials approved by the Director.
               (2) Timing. While a deleader is performing work, no one other than those authorized by
               454 CMR 22.12(2)(a)5.: Restriction of Access shall be permitted on the worksite until the
               deleader completes final clean-up in accordance with 105 CMR 460.160(D)(1), except as
               permitted in policies approved by the Director or the Department of Standards.

           (C) Licensed deleaders must perform all abatement and containment activities not listed in 105 CMR
           460.175(A) or (B).

           (D) All authorized persons who will be performing low- or moderate-risk abatement and/or
           containment activities, shall do such work in compliance with the provisions of 105 CMR 460.000,
           shall undergo training, and in the case of owners and owners’ agents, take a course of instruction. The
           Director shall establish and revise as necessary the respective content and requirements for the
           following: low-risk abatement and/or containment instruction for owners and owners’ agents;
           encapsulation instruction for owners, owners’ agents, authorized persons and deleaders who did not
           receive encapsulation training as part of their deleader training; and moderate-risk abatement instruction
           for owners and owners’ agents. All required instruction for owners and owners’ agents shall include
           passing an examination issued or approved by the State Program. Deleaders and authorized persons
           must be trained and licensed pursuant to, and adhere to the additional requirements of, 454 CMR
           22.00: Deleading and Lead-safe Renovation Regulations.

           (E) Authorization to Perform Low-and-moderate-risk Abatement or Containment. An owner or
           owner’s agent must submit to the State Program proof that he or she has successfully completed the
           instruction required by the Director pursuant to 105 CMR 460.175(D), and in the case of an owner’s
           agent, has attained 18 years of age. The State Program shall then issue an authorization to the owner
           or owner’s agent documenting that he or she has met these requirements and is thereby authorized to
           perform low- and/or moderate-risk abatement or containment, as applicable.

           (F) Any abatement and/or containment activities performed by an authorized owner and/or owner’s
           agent that exceed the scope of activities he or she is authorized to perform by 105 CMR 460.175, or
           which are undertaken by an owner and/or owner’s agent who has not been authorized as required by
           105 CMR 460.175(E), shall be considered unauthorized deleading under 454 CMR
           22.00: Deleading and Lead-safe Renovation Regulations and 105 CMR 460.000 and subject to
           all the penalties thereof. Any abatement and/or containment activities performed by a licensed
           authorized person that exceed the scope of activities authorized by 105 CMR 460.175 and 454 CMR
           22.00, or which are undertaken by a renovator who is not licensed to perform moderate risk deleading,
           shall be considered unauthorized deleading under 454 CMR 22.00 and 105 CMR 460.000 and
           subject to all the penalties thereof.
