Building Official Memo on Permitting Operations during COVID-19


Monroe County Building Department is open to the public with a phased and changed approach for services. Services will be provided, as indicated below, between 8:30 am and 3:00 pm at the Key Largo Permitting Office, Marathon Permitting Office, Stock Island Office, and Ocean Reef Office. 

A Drop-off and Pick-up system is in place for all offices, accepting all permitting related documents including permit applications, corrections, revisions, and post-issuance related items including but not limited to roof truss plan and permit clarifications.  We will not process the application or other documents when you drop them off. Instead, they will be processed after an overnight “waiting period.” 

All submissions must contain a Transmittal Form

You may also mail your documentation/payment (checks) to the office where your permit is or would be reviewed by plans examiners:

  • Key Largo: 102050 Overseas Highway, Key Largo, FL 33037
  • Marathon: 2798 Overseas Highway, Suite 300, Marathon, FL 33050
  • Stock Island: 5503 College Road, Suite 203, Key West, FL 33040
  • Ocean Reef: 11601 CR 905, Key Largo, FL 33037

Use the MS Excel Fee Estimator (found on the Permitting Fees, Forms & Applications webpage under Building Department Fees section) to calculate the estimated amount of your payment needed for submittal at drop-off. If the fee amount you submit isn’t exactly correct, this will be adjusted at permit issuance or you will be asked to mail in the difference needed.


Pick-up service is only available for those authorized individuals that have replied to the permit-related County-generated email and provided the location and date they will be present for the pick-up.   

Boxes/ envelopes for pick-up will be identified with the name of the authorized individual, permit number, and pick-up date provided; and placed in a clearly identified area inside each office/building for pick-up.

INSPECTIONS (Select to go to Inspections web page for additional information regarding inspections)

Governor DeSantis issued Executive Order Number 20-52 on March 9, 2020 declaring a state of emergency because of COVID-19 which allows the Building Official to extend Building Permits and the Planning Director to extend Development Orders.   

All Building Permits and Development Orders active on March 9, 2020 are eligible to receive an additional 6 months to receive a passed inspection (once a passed inspection occurs then the permit would again be subject to the continuing 180-day passed inspection cycle.) 

The permit holder is required to notify the county in writing (email is acceptable) and identify the specific permit/development order of their intent to exercise this extension within 90 days after the termination of the emergency declaration. The termination date will be forwarded once it is known.  

Building Permits, for example, if the permit had an inspection due by April 2 (after March 9,) then the requirement to have that inspection would be extended 6 months to October 2.

Please send Building Permit extension requests to Sebben-Crystal@MonroeCounty-FL.Gov or Monroe County Building Department, 102050 Overseas Highway, Key Largo, FL 33037,  Attn: Crystal Sebben – Permit Extension.


Staff will contact those Permit Holders who are ready to receive COs. Contact will primarily be made via email.
