Public Storage and Extra Space Storage are the two largest operators in Miami — between them they run roughly 140 locations across Miami-Dade. On paper they look identical: orange vs green branding, same unit sizes, same move-in promos. The real differences show up in average pricing, post-promo rate increases, and which neighborhoods each chain actually covers.
This comparison uses each chain's own published 2026 Miami pricing plus renter-reported rate-increase patterns. Where we cite numbers, they're the companies' advertised averages — your specific quote will vary by location and availability.

Public Storage operates ~76 facilities in the Miami metro area. Their coverage is densest inside the urban core — Downtown, Little Havana, Allapattah, and along major corridors like SW 8th Street and Biscayne Boulevard. Of those 76 locations, about 65 offer climate-controlled units and 31 accept car/vehicle storage.
Extra Space Storage operates 60+ facilities in the same footprint, with strength in the suburbs — Doral, Hialeah, Kendall, and the northwest corridor near Miami Executive Airport. They list roughly 75 climate-controlled locations and are typically newer builds than Public Storage's older urban sites.
Practical takeaway: if you live in Brickell, Downtown, or Little Havana, Public Storage probably has a closer location. In Doral, Kendall, or the suburbs, you'll often have both options within a few miles — compare on price, not brand.

Reading the table: Public Storage wins on small-unit averages and large-unit advertised lows; Extra Space often wins on climate-controlled promos and suburban drive-up pricing. The "low" numbers are promo rates — they tell you the floor, not what you'll pay in month 7.
Street-price reality: across both chains, a standard 10x10 in Miami lands around $150-$170/month after promos expire. Neither chain is structurally cheaper — the winner is whichever specific location near you is running the better promo this month.
Promo Deals: 50% Off vs $1 First Month
The chains compete with different promo structures:
- Public Storage: typically runs "50% off first 3 months" or "$1 first month" on select units. The 50%-off-for-3-months deal has the highest total dollar value if the base rate is high — a $200 unit saves you $300 over three months.
- Extra Space: leans on "$1 first month" and "first month free." Simple, easy to calculate, but worth less in absolute dollars on expensive units ($200 saved vs $300 under Public's 50% deal).
The trap both chains share: promo pricing disappears fast, and online rates are usually lower than walk-in rates. Reserve online even if you plan to sign in person — the web rate typically locks for a short window.
Short-stay math: for a 2-3 month rental, compare total cost including admin fee and mandatory insurance, not the headline promo. For a 12+ month stay, the post-promo rate matters far more than month one.
