§ 154.003 REDUCTION OF FEES FOR SECOND DWELLING UNIT. (A) When a building permit is sought for the addition of a second unit to a property containing only one existing single-family dwelling unit, regardless of the zoning district in which the property is located, the amount of the in lieu fee to be paid at the time the Certificate of Occupancy is issued for that second unit shall be 50% of the amount required under the formula established in § 154.002(B) for so long as the property remains developed with only two units. (B) In the event a third (or more) residential unit is constructed on the property for which the reduced in lieu fee established in division (A) has been paid, the amount of the in lieu fee fees to be paid at the time the Certificate of Occupancy is issued for such third unit shall be calculated pursuant to the formula established in § 154.002(B) plus an additional amount equal to 50% of the in lieu fee for the second dwelling unit shall also be collected.

Violations & Fines
A Certificate of Occupancy or Temporary Certificate of Occupancy will not be issued for a new dwelling unit, including a second unit, until the § 154.002/§ 154.003 park in-lieu fee is paid under § 154.002(E). Adding a third unit without paying the § 154.003(B) surcharge on top of the standard formula fee blocks occupancy of that unit until the shortfall is resolved.
