How it Works

Download and fully complete the application. Submit via U.S. Mail or in person with the following (if applicable):

1.) Two (2) copies of properly marked site plans for residential properties that outdoor heating/cooling equipment and tanks are being installed or relocated in accordance with the provisions in the Montgomery County Zoning Ordinance setback requirements. Link to Zoning Diagrams and Examples page

Two (2) copies of ACCA Manual J Calculations (Eighth edition) for residential properties that duct work is being installed/added to an existing or new system in compliance with the International Residential Code Sections N1103.6 Equipment Sizing & M1401.3 Sizing. If the required Manual J calculation is not submitted with the permit application, the application will not be processed.

A non-refundable fee payment must accompany the application. DPS accepts credit card, check (with proper ID) and cash. No applications or payments will be accepted or processed by fax or email

How it Works

The application will be reviewed for completion and accuracy. Upon initial approval by the permit technicians, the applicable data will be entered and the application will be given a permit number. If necessary, the application and supporting documents will be forwarded to our zoning review staff for approval. Mail will be forwarded by the permit technicians to required review staff. Applicants in the office will be sent to review their documentation in person with zoning staff. Upon approval, the site plan will be stamped and the applications forwarded back to the permit technicians.

How it Works

Once all approvals are met, the permit technician will stamp the Manual J calculations, intake the Departments copies for recordation, and send the permit to the be paid at the fee payment office. Mail will be forwarded by DPS staff and, in person applicants will be entered in to the queue to physically pay at the cashier’s window. Once paid & issued, the applicant will be handed or mailed two (2) copies of the approved permit, one (1) copy of the approved/stamped site plan and one (1) copy of the stamped Manual J calculation (if applicable), as well as the receipt.

How it Works

All DPS issued permits must be conspicuously posted and approved plans immediately available for review at all times at the location of work. The project must be constructed in accordance with the approved plans and any plan review approval comments. All required inspections must be obtained and can be scheduled online using DPS’ eServices program or by calling Montgomery County 311 (240-777-0311). After final inspection approval, the approved plans and permit should be stored in a safe location for future reference.
