Get a Supplemental Permit

DCRA now lets you apply for, pay for and get your supplemental building permits online.  These permits are required to install supplemental systems in buildings, per § 105.1.13 of the DC Municipal Regulations (DCMR). Only licensed DC contractors for each specific trade may apply for these permits. You may be required to complete a building permit for the supplemental permit.
