Interior alterations do not require the Alderman’s approval, however, the Department of Building's 10-day permit waiting period can be waived for self-certified projects, with an aldermanic acknowledgment letter.
To apply for an aldermanic acknowledgment letter, please submit your request and permit application from the Department of Buildings (first page of permit application only) to our office via fax to (312) 642-0420. Include complete contact information, including your fax and telephone numbers for return correspondence. Please expect a minimum 3-5 day turnaround for the signed application or approval letter.
Please note - residential interior alterations require an approval letter from the condominium association or board for processing.
