Here is the entire clause:
MAINTENANCE, ALTERATIONS, DECORATING
1. Maintenance, Repairs and Replacements. Each Unit Owner shall furnish and be responsible for, at his own expense, all of the maintenance, repairs and replacements within his own Unit. Maintenance, repairs and replacements of the Common Elements shall be furnished by the Board as part of the common expenses, subject to the rules and regulations of the Board.
The Board may cause to be discharged any mechanics' lien or other encumbrance which, in the opinion of the Board, may constitute a lien against the Property of Common Elements, rather than against a particular Unit and its corresponding percentage of ownership in the Common Elements. When less than all the Unit Owners are responsible for the existence of any such lien, the Unit Owners responsible shall be jointly and severally liable for the amoun necessary to discharge the same and for all costs and expenses (including attorneys' fees) incurred by reason of such lien.
Whenever the Board shall determine, in its discretion, that any maintenance or repair of any Unit is necessary to protect the Common Elements or any other portion of the Building, the Board may cause a written notice of the necessity for such maintenance or repair to be served upon such Unit Owner, which notice may be served by delivering a copy thereof to any occupant of such Unit, or by mailing the same by certified or registered mail addressed to the owner of the Unit. If such Unit Owner fails or refuses to perform any such maintenance or repair within a reasonable time started in the notice (or any extension thereof approved by the Board) the Board may cause such maintenance and repair to be performed at the expense of such Unit Owner.
If, due to the act or neglect of a Unit Owner, or of a member of his family or household pet or of a guest or other authorized occupant or visitor of such Unit Owner, damage shall be caused to the Common Elements or to a Unit or Units owned by others, or maintenance, repairs or replacements shall be required which would otherwise be at the common expense, then such Unit Owner shall pay for such damage and such maintenance, repairs and replacements, as may be determined by the Board, to the extent not covered by insurance.
The Board shall have exclusive authority to take, or refrain from taking, any action pursuant to this Article VIII, Section 1. All expenses which, pursuant to this Section 1, are chargeable to any Unit Owner, may be specifically assessed to such Unit Owner and shall be payable by such Unit Owner as prescribed by the Board.
2. Limited Common Elements. Any charge or expense in connection with expenditures for the Limited Common Elements shall be assessed only against that Unit to which such Limited Common Elements are assigned.
3. Alterations, Additions or Improvements. No alterations of any Common Elements or any additions or improvements thereto, shall be made by any Unit Owner without the prior written approval of the Board. Any Unit Owner may make alterations, additions and improvements within his Unit without prior written approval of the Board, but in any event such Unit Owner shall be responsible for any damages to other Units, the Common Elements, or the Property as a result of such alterations, additions or improvements. Nothing shall be done in any Unit, or in, on or to the Common Elements which will impair the structural integrity of the Building or which would structurally change the building.
4. Decorating. Each Unit Owner shall furnish and be responsible for, at his own expense, all of the decorating within his own Unit from time to time, including painting, wall papering, washing, cleaning, paneling, floor covering, draperies, window shades, curtains, lamps and other furnishings and interior decorating. The use of and the covering of the interior surfaces of windows, whether by draperies, shades or other items visible on the exterior of the Building, shall be subject to the rules and regulations of the Board. Decorating of the Common Elements (other than interior surfaces within the Units as above provided) and any redecorating of the Units to the extent made necessary by any damage to existing decorating of such Units caused by maintenance, repairs or replacement work on the Common Elements by the Board, shall be furnished by the Board as part of the common expenses. Anything in this paragraph to the contrary notwithstanding, all Units located above a Unit shall have fully carpeted hallways and at least 80% Of all other floor areas shall be carpeted excepting therefrom, kitchen and bathroom floor areas.
