Departmental Operations Updates
In an effort to be proactive regarding FY26 budget challenges, Howard County has implemented "Energy Saving Days". During these dates many County buildings, including the George Howard Building, will be closed and/or energy use will be drastically reduced. DILP will remain operational with employees available by phone, email and off-site meetings, as needed. Please plan ahead to ensure that you meet submission deadlines; Energy Saving Days do not impact electronic submissions.
The remaining 2026 Energy Savings Day are below:
- June 29th, 30th
- July 1st, 2nd
- August 3rd, 4th, 5th, 6th, 7th
- November 23rd, 24th, 25th
Beginning February 1, 2025, the County will cease absorbing merchant services fees associated with all payments made by credit card or ACH. These fees will now be paid by the customer and will be clearly shown during checkout at the completion of their transaction.
