Notice: As a result of many inquiries regarding the items outlined below, effective October 13, 2010, the Department of Inspections, Licenses and Permits requires the following in connection with HVACR installations:
- Manual J will only be required for finished basements when new equipment is installed to serve that area
- No Manual N required if drawings are engineered stamped or certified by the Master HVACR contractor installing the same mechanical system
- All change out of existing HVACR equipment will require a block house load calculation at time of permit application
- Electrical permit is required when the contractor is relocating or replacing a unit that requires the resizing of electrical conductors and/or circuit breakers which also includes the disconnect replacement.
The Department of Planning and Zoning will review all site plans associated with the installation of a Geothermal System prior to the issuance of required mechanical permit. A site plan of the property depicting the size and location of the proposed system shall be required. A Planning Assistant will review the site plan to assure the proposed system is not located in a forest retention area, a Natural Resource District, a recorded easement, critical area or floodplain, etc.
Once the Planning Assistant has verified the system is acceptable, the site plan will then be stamped approved by Zoning, signed and dated. A copy of this approved site plan will be filed in the Zoning Office and a copy will be attached to the mechanical permit. Contact the Plumbing Services Division at 410-638-3215 with any questions in reference to these requirements.
Application for a mechanical permit must be made by a registered master, master restricted or limited HVACR. A Manual J or acceptable unit sizing documentation is required. Permit information:
