New Credit Card, E-Check/ACH Payment Portal
Montgomery County Building Regulations is excited to announce the release of a new credit card and Echeck/ACH payment portal through our partnership with Point & Pay. Effective January 4, 2021, our online payment options are expanding to include debit card, credit card and Echeck payment options.
The following service fees will be applied to each transaction through the new payment portal.
Credit/Debit Cards: 2.30% with a minimum service charge of $2.00 per transaction.
Echecks/ACH: $0.50 per transaction
The new online payment portal will allow entry of multiple items in a single transaction. What this means is that customers can complete payments for more than one permit or item in a single transaction and the service fee will be applied to the transaction – Echeck’s are only $0.50 per transaction and credit/debit cards would be calculated per the 2.30% minimum $2.00 transaction criteria. Please follow this link to visit the new payment portal: Make Online Payment.
Electronic project submission
We have started a prototype program for submitting one-, two- or three-family residential projects electronically. This program allows you to submit drawings and plan changes via email. Every submittal must be a flattened PDF (no layers) and must be accompanied by a completed Residential Application Form or a Supplemental Document Submittal form. The email address is firstname.lastname@example.org.
Fee payments can be made by mailing a check or using our electronic Online Payment portal, but for new submittals, you will need to wait until our Permit Clerk has validated the submittal and assigned it a “Case Number” (once the project is approved, that will be referred to as a Permit Number).
You are welcome to call our office for more information.
