22 feet width units B2601217, B2601512, B2601514, B2601513 The District of Columbia Mechanical Code is currently in the 2017 cycle, which does not have the A2L refrigerant requirements that later ICC codes have. Therefore, the DC Department of Buildings has elected to allow for the installation of A2L refrigerant piping, as is allowed by the 2024 International Mechanical Code. Section 1109.2.5 of the 2024 IMC requires that refrigerant piping penetrating two or more floor/ceiling assemblies be enclosed in a fire-resistance-rated shaft enclosure. It also lists exceptions. Exception 2 states: Piping in a direct refrigeration system using Group A1 refrigerant where the refrigerant quantity does not exceed the limits of Table 1103.1 for the smallest occupied space through which the piping passes. The 2024 IMC borrows language from ASHRAE 15-2022, but changes the language in this exception. This code modification request is to modify the code to utilize language directly from ASHRAE 15-2022. The difference we would like the DOB to consider is the second exception. Instead of specifying A1 refrigerants, the exception states: Piping in a high-probability system where the refrigerant concentration does not exceed the amounts shown in ASHRAE Standard 34, Table 4-1 or 4-2, for the smallest occupied space through which the piping passes.

Published by the District as assessment data, separately from the permit record above, and current as of the District’s own assessment cycle rather than today. An assessment can lag construction by a cycle, so a property with a recently issued permit may still be assessed as it was before the work. Owner details are published by the jurisdiction but are deliberately not shown here.
These are the permits published by the jurisdictions listed above. A project usually depends on approvals from other agencies that publish nothing machine-readable — a forest conservation exemption, a well completion report, a sediment control or grading plan, a utility connection, a homeowners’ association sign-off. Their absence here is not evidence they were not required, and the gaps between the dates above are usually where they happened. Rows labelled “Issued” are ISSUED permits — Washington DC publishes an issue date and no project valuation at all. Records are grouped by normalised address text, so the same property may also appear upstream under a different spelling. Verify scope, dates, and contractor information with the issuing jurisdiction before bidding, quoting, or performing work.
