SEC. 151.07. AUTHORITY OF THE DEPARTMENT AND THE COMMISSION TO GRANT INDIVIDUAL RENT ADJUSTMENTS. A. Authority of the Department . 1. The Department, in accordance with such regulations and guidelines as the Commission may establish, shall have the authority to grant adjustments in the rent for a rental unit or units located in the same housing complex upon receipt of an application for an adjustment filed by the landlord of the unit or units if it finds that one or more of the grounds set forth in this Subdivision exist. Nothing in this Section shall prevent the Department from granting rent adjustments under more than one provision of this Section, provided the rent adjustments are for different work or improvements. The Department shall not grant a rent adjustment for a rental unit under more than one provision of this Section for the same work or improvement. The Department shall not process any applications for rent adjustments under this Section if the landlord has not paid all outstanding fees imposed pursuant to Section 151.05, Section 161.352 and Section 161.901 of this Code. (Amended by Ord. No. 184,080, Eff. 2/19/16.) a. That on or after April 1, 1978, the landlord has completed a capital improvement with respect to a rental unit and has not increased the rent to reflect the cost of such improvement. If the Department so finds, the landlord shall be entitled to a permanent monthly rent increase of 1/60th the average per unit capital improvement cost; provided, however, any rent adjustment for a capital improvement granted by the Department between February 13, 1981, and May 31, 1982, shall terminate after five (5) years. Except that, for any capital improvement work for which a rent increase application is filed with the Department on or after October 1, 1989 the landlord shall only be entitled to a temporary monthly rent increase of 1/60th of fifty percent (50%) of the average per unit capital improvement cost for a period not to exceed six (6) years. This temporary monthly surcharge shall not exceed $55.00 per month for each rental unit unless agreed upon in writing by a landlord and a tenant. If the surcharge, as calculated under the above formula, would exceed $55.00 per month, then the surcharge period of six (6) years may be extended until the allowable capital improvement expenses are recovered.
