What ZIP Code Is Snell Isle In? St. Pete Guide

Snell Isle ZIP Code: The Quick Answer

Snell Isle is in ZIP code 33704, St. Petersburg, Florida. The island shares that postal code with adjacent Old Northeast — but in terms of home prices, lot sizes, and flood exposure, Snell Isle is its own world. If you own here, that address carries serious weight with buyers.

What's Actually Inside ZIP 33704

ZIP 33704 covers a roughly two-mile corridor running north from downtown St. Pete, along the western shore of Tampa Bay. The main neighborhoods inside it are:

• Snell Isle — the 275-acre island bounded by Coffee Pot Bayou and Tampa Bay, accessed primarily off Snell Isle Boulevard NE
• Old Northeast — the walkable historic grid between 4th Street N and the waterfront, loaded with Craftsman bungalows and Spanish Eclectic homes from the 1920s
• Portions of Historic Uptown — the blocks south of 18th Avenue N that blend into the 33704 boundary

Within that ZIP, Snell Isle sits at the high end on almost every metric: lot size, list price, flood exposure, and insurance cost. A bungalow on 22nd Avenue NE in Old Northeast and a waterfront estate on Brightwaters Boulevard NE are both "33704" — but they're priced in different universes.

Snell Isle Home Values in 2026

The Pinellas County single-family median was $469,900 in April 2026 (Florida Realtors), up roughly 1.1% year-over-year. Snell Isle pulls well above that countywide figure.

Non-waterfront homes on the interior of the island — think quiet streets like Snell Isle Boulevard and North Shore Drive NE — are typically priced in the $700,000–$1.2 million range depending on lot size and condition. Canal-front and open-bay homes regularly list from $1.5 million to $4 million+, and teardown lots on the water have traded above $700,000 on their own.

One of the search signals I track shows significant search volume for "custom home builders Snell Isle" — and that makes sense on the ground. The island has been an active teardown-and-rebuild market for years. Wide bayfront lots, 75-to-100-foot canal frontage, and the island's deed-restricted character attract high-end builders completing projects in the $1.5M–$4M range. If you own an older home on a desirable lot, buyers may be pricing the land, not the structure.

A Zestimate won't capture that nuance — Zillow's automated valuations carry a ~7% median error rate for off-market homes in Florida markets like this one, where a 10-foot difference in lot elevation or 20 feet of additional water frontage can swing value by six figures. Real comps from a local agent are the only way to know.

Flood Zones in 33704 / Snell Isle

This is the single most consequential homeownership cost factor for Snell Isle buyers and sellers. Here's the breakdown:

Most of Snell Isle is FEMA Zone AE — the 1%-annual-chance floodplain. That means:

• Federally backed mortgage holders (FHA, VA, conventional with Fannie/Freddie) are required to carry flood insurance
• NFIP premiums run $1,200–$3,500 per year for a standard $250,000 building policy on a St. Pete single-family home under Risk Rating 2.0
• Under Risk Rating 2.0, pricing is individual, not zonal — two homes on the same Snell Isle canal can pay $1,400 and $2,800 per year, based on finished-floor height relative to Base Flood Elevation (BFE), distance to open water, and foundation type
• Below-BFE finished floors or VE-zone exposure (coastal wave action) push premiums above that range — sometimes significantly

The post-Helene and post-Milton environment (September and October 2024) has made flood insurance a first-line buyer objection on Snell Isle. Sellers who have an Elevation Certificate on file — which costs $400–$900 from a licensed Florida surveyor — can document favorable floor elevation to buyers and potentially reduce the insurance quote a buyer faces at closing. That piece of paper can directly affect how many offers you get and at what price.

Schools Serving the 33704 / Snell Isle Area

The public school assignment for Snell Isle runs through three Pinellas County schools:

Some families opt for Northeast High (also strong), and private options within a short drive include Admiral Farragut Academy on the island itself, plus several Catholic and independent schools along the 4th Street N corridor.

If schools are a deciding factor in your purchase or pricing strategy, worth noting: North Shore Elementary attendance-zone addresses carry a measurable premium in this part of 33704.

Selling a Home in 33704: What Actually Matters

If you own on Snell Isle and are thinking about selling in 2026, here's what I'm seeing move the needle with buyers right now:

1. Flood insurance documentation — Buyers are asking for it on the first showing. If your current annual premium is below $1,500, that's a marketable data point. If it's above $3,000, be prepared for buyer negotiation on price or seller concessions.
2. Elevation Certificate — If you have one, pull it. If you don't, consider getting one before listing. At $400–$900, it often pays for itself in reduced buyer risk perception.
3. Lot specifics for teardown buyers — Canal-front homes under 2,000 square feet on 80+ foot lots are drawing serious attention from custom builders. The right comp set needs to account for land value, not just living area.
4. Custom build demand — The search data is clear: there is sustained buyer interest in custom-home lots on Snell Isle. If your property has tear-down potential, I'll structure the comp pull to reflect that buyer pool, not just the retail end-user pool.
5. Comparable sales, not Zestimates — The algorithm doesn't know your specific bay view, your lot orientation, or that the home two doors down just sold as a teardown for land value. I will.
