Bay St. Louis, the artful end of the Coast.

I'm not from Bay St. Louis — I'm about an hour east in Ocean Springs, where I moved from California in March 2005, five months before Katrina took my house. I stayed and rebuilt. That's why I can talk about this end of the Coast honestly: Bay St. Louis and Waveland took the worst of that storm, and twenty years later the rebuild is still part of the landscape. Below: what Old Town and the inland subdivisions actually look like, why the flood and insurance math here is the most serious on the Coast, how the schools are organized, and the local pieces I'd want a New Orleans weekender or a relocating family to know before they put in an offer.

The town in one paragraph

Bay St. Louis is the seat of Hancock County, the westernmost coast county and the most "Louisiana-adjacent" stretch of the Mississippi Gulf Coast — New Orleans is about 50 minutes west on I-10, which runs through the county to the north. The heart of the place is Old Town: a historic, walkable downtown along Beach Boulevard and the Main Street / Second Street grid, full of galleries, restaurants, and boutiques. It draws New Orleans weekenders, retirees, artists, and remote workers, and it has a real arts identity — Second Saturday art walks, the Depot District, working harbor and municipal pier. It feels less polished and more bohemian than the eastern Coast towns, in a good way. Day-to-day it's a small, water-facing town where the gallery openings and the shrimp boats share the same few blocks.

This is the Katrina end of the Coast. When the storm came ashore on August 29, 2005, Hancock County caught the worst of it — surge peaked around 27 to 28 feet, and Bay St. Louis and neighboring Waveland were essentially leveled. Twenty years on you'll still see empty lots and homes lifted high on pilings. That isn't decay; that's the rebuild. Understanding it is the first step to understanding the housing stock, the build years, and the insurance bills here. I'll handle it honestly throughout this guide, because I lived through that storm myself, an hour east.

The areas, by geography

Bay St. Louis splits roughly into Old Town and the inland subdivisions, with Waveland and Diamondhead as nearby Hancock options worth knowing. Each carries a different price band and a different flood and insurance profile.

OLD TOWN / BEACHFRONT

Old Town & the Beach Boulevard waterfront

Walk-to-everything

The historic, walkable core — Beach Boulevard along the water and the Main Street / Second Street grid running back from it. Galleries, restaurants, boutiques, the harbor and municipal pier. A mix of pre-Katrina survivors, elevated post-storm rebuilds on pilings, and lots that still sit empty twenty years on. The most expensive part of the city.

Flood-zone heavy: VE on the immediate beachfront, AE through much of Old Town and the first mile back. Most of the historic core also sits in the local + National Register historic district — exterior changes visible from the street go before the Bay St. Louis Historic Preservation Commission. Mortgage flood insurance required almost everywhere here; coastal construction rules (pile foundations, breakaway walls below BFE) apply to rebuilds. Verify the district boundary and the flood zone for any specific address before counting on either.

INLAND / NORTH

Inland Bay St. Louis subdivisions

Drive-to-Old-Town

The neighborhoods running north away from the water — toward and across the I-10 corridor. Higher ground, generally newer housing stock, and a different price band from the waterfront. This is the lower-flood-exposure half of the area and where a lot of the everyday family inventory lives.

Higher and farther from the surge line means more Zone X and lower flood-insurance exposure than Old Town — though you still verify per address, because AE pockets follow the bayous and low spots even inland. No historic-district overlay up here. Easier access to I-10 for the commute toward Slidell and New Orleans west or Gulfport east.

NEXT DOOR · WAVELAND

Waveland

Drive-only

The city adjacent to the south and west, sharing the same beach and the same Katrina story — Waveland took surge that erased nearly everything in 2005. Today it is a more affordable, mostly residential neighbor, with its own stretch of waterfront and a lot of single-family inventory at a lower price point than Old Town.

Same flood realities as the rest of the immediate coast — VE on the beachfront, AE through much of the residential grid, more X as you move inland and north. Worth looking at alongside Bay St. Louis if Old Town pricing is out of range and you still want to be close to the water and the same school district.

NEXT DOOR · DIAMONDHEAD

Diamondhead

Drive-only

A planned community to the northeast, up off I-10 — golf, a marina, and a more master-planned, suburban feel than historic Old Town. Newer housing stock on the whole and a popular landing spot for buyers who want Hancock County and water access without the beachfront flood profile or the historic-district rules.

Being inland and up off the immediate coast, much of Diamondhead carries lower flood exposure than the beachfront — but the waterway and canal lots have their own AE considerations, so verify per parcel. Different feel and different price math from Old Town; a real alternative inside the same county.

A note on pricing. Directional only — verify against current MLS before you count on a number. Mid-2020s, Old Town homes tend to run roughly $350K–$900K, with Bay St. Louis waterfront stretching $600K to $2M+. For context, Waveland single-family tends to fall around $180K–$400K, and inland Hancock County runs roughly $150K–$300K. These bands move; treat them as a starting orientation, not a quote.

Schools

Bay St. Louis and Waveland are served by the Bay-Waveland School District. I'm not going to pretend to map attendance boundaries or grade individual schools from an hour away — that changes, and you should pull it fresh. What I can point you to is where the real information lives.

District Bay-Waveland School District (serves Bay St. Louis and Waveland)
Ratings Annual accountability ratings published at mdek12.org
Private (Catholic) Our Lady Academy · St. Stanislaus College Prep — both long-established Bay St. Louis schools

District ratings change year to year — the Mississippi Department of Education publishes annual accountability ratings at mdek12.org. Don't take any single year's letter grade as the whole story; check the trend. On the private side, Bay St. Louis is home to two long-established Catholic schools — Our Lady Academy and St. Stanislaus College Prep — which are well known across the Coast. Verify current programs, grades served, and admissions directly with each school.

Flood profile, in plain terms

Bay St. Louis carries the heaviest surge history on the Mississippi Coast. The flood map here is not a formality — it's the center of the buying decision near the water. The short version:

For any specific address, pull the current FEMA FIRM panel at msc.fema.gov before counting on a zone designation. Designations can change after map updates. I have a longer walk-through of the FEMA zones on the Coast flood-zone guide.

Market beats every Bay St. Louis buyer or seller should hear

Stable patterns — not month-to-month price talk. These are the things that come up in every real Bay St. Louis conversation.

The Katrina backdrop
Bay St. Louis and Waveland took the worst of Hurricane Katrina in 2005 — surge peaked around 27–28 feet in Hancock County and the immediate coast was essentially leveled. Twenty years later you still see empty lots and elevated rebuilds on pilings. That history is written into the housing stock, the build years, and the insurance math. It is not a footnote here; it is the context for everything south of high ground.
The New Orleans pull
Hancock County is the westernmost, most Louisiana-adjacent part of the Coast — New Orleans is roughly 50 minutes west on I-10. A meaningful share of demand here comes from NOLA weekenders and relocaters. That outflow shapes Old Town pricing and the second-home market in ways the eastern Coast counties feel less.
Insurance reality
Coastal homes here typically need three policies: an ex-wind homeowners policy, a separate wind/hail policy through the Mississippi Wind Pool (MWUA), and flood through the NFIP or a private flood carrier. Named-storm deductibles are a percentage of the dwelling value, not a flat dollar amount — 5% of a $400K dwelling is $20,000 out of pocket. Premiums on the water are real money. Get a coast-local quote before you fall in love with a beachfront listing.
Build era & elevation
Pre-2005 slab homes in flood zones are the hardest to insure affordably. Post-storm elevated builds on pilings tend to insure cleanest. A current Elevation Certificate matters a lot on an elevated rebuild — it can be the difference between a workable premium and a brutal one. The build year and the elevation are among the first things to check on any listing near the water.
Stennis drives demand
Stennis Space Center — NASA, Navy, NOAA, Coast Guard, and contractors, 5,000-plus personnel — sits nearby and is a steady source of Hancock County housing demand. Federal and contractor workers are a real share of the inland buyer pool.
Talk to Rob signal
New Orleans buyers scouting a weekend place, retirees and remote workers drawn to Old Town, and Stennis-area families looking inland are the most common Bay St. Louis inbound. I am about an hour east in Ocean Springs and I went through Katrina here myself — so I can talk straight about the rebuild story and the insurance math without the sales gloss.

Day-to-day in Bay St. Louis

Stuff that's actually here, in case you're trying to picture life on the ground:

The historic-district thing. Most of Old Town sits in a National Register and local historic district, and the Bay St. Louis Historic Preservation Commission reviews exterior changes that are visible from the street — windows, roofing, additions, fences. Interior work and routine maintenance generally aren't regulated, but buyers regularly miss this until they want to swap out windows or add on. If you're buying in Old Town, confirm whether the address is in the district and what the current ordinance requires before you plan a renovation.

Who tends to buy here

The Bay St. Louis buyer pool I see breaks down roughly like this — useful context whether you're moving in or thinking about who might end up in your house when you sell:

Thinking about Bay St. Louis?

Whether you're scouting a weekend place from New Orleans, weighing Old Town against Waveland or Diamondhead, or just trying to make sense of the flood and insurance math on a beachfront listing — happy to talk. I'm an hour east in Ocean Springs, I went through Katrina here myself, and I can give you a straight read on the rebuild story and the numbers. Once I'm licensed (mid-2026), I'll be able to bring this into a full buyer or seller conversation. For now: it's a neighborly call, not a service call.
