Extra Space Storage Pulls $14M Permit in Westchester

Miami-Dade County issued a $14 million building permit on August 26 for a four-story, 99,718-square-foot project at 888 SW 68th Ave in Westchester, and the developer of record is Extra Space Properties, a name that matches the entity-naming pattern Extra Space Storage Inc. (NYSE: EXR) uses for its subsidiaries in SEC filings. This newsroom tracks the permit directly off Miami-Dade RER’s own building permit dataset.

Why it matters

We pulled this off our own permit wire, the same Miami-Dade RER building permit feed we check every morning, and cross-checked the address against the county’s list of active filings from the past two weeks. It is the largest permit in that window nobody else has flagged, because every bigger one, the $60 million Little Havana tower, the $263 million Fisher Island project, the Grupo T&C Edgewater permit, the South Miami hotel, already ran here. The permit’s 876-unit count is filed under “multifamily” in the county’s coding, but a 99,718-square-foot building averaging 114 square feet per unit is a storage-unit count, not an apartment count, and the site sits one block from an existing Extra Space Storage facility at 910 SW 68th Ave. That reads as expansion, not new-market entry, in a submarket where self-storage has quietly kept building through a cycle where multifamily financing has not.

The numbers

Permit 2026067570 declares $14,000,000 in value for 99,718 square feet across four floors at 888 SW 68th Ave, with Millennium Makeover Inc. listed as contractor. Extra Space Properties is not a name on our South Florida developer watchlist, its footprint here is industrial storage, not condo or rental towers, and that is exactly why it does not show up in the usual developer coverage even though the dollar figure clears our threshold.

What’s next

The next verifiable marker is a certificate of occupancy tied to the same permit number, which would confirm the timeline from issuance to opening. For builders and construction firms watching where dollars are still moving in South Florida, a REIT quietly expanding an existing self-storage footprint is a different signal than another luxury tower announcement, and it is one only a direct read of the permit record surfaces.
