If you've been looking on the island

You already know the questions.

Windstorm, flood, rental rules, historic review, parking. Every house on Galveston Island comes with the same list, and most listings make you ask. Here it is up front — the house first, the island below.

"Which bedroom is the primary?"
The smallest one, and it is upstairs. The primary measures 16'1" × 10'5", about 167 sq ft. The other two are 15'10" × 13'5" and 15'10" × 13'6", about 212 and 214. All three are on the second floor, along with both full baths. If you need a large first-floor suite, this is not that house. If you need three rooms nobody has to fight over — parents and adult kids, two couples splitting a beach house, roommates, or a rental where every bedroom books at the same rate — it is.
"Where are the bathrooms?"
Two full baths upstairs, a powder room down. The full baths measure 6'9" × 10'5" and 6'11" × 9'2". The powder room (2'8" × 5'2") sits off the entry hall, so guests never climb the stairs.
"What's on the first floor?"
An entry hall, living room, dining room, kitchen and powder room. The entry hall is 24'9" long. The living room (15'9" × 13'4") and dining room (15'9" × 13'3") share the same width and open to each other through a cased opening. The kitchen is 23'4" long and 10'5" wide, with an island, a gas range and a separate pantry. There are two staircases — one off the kitchen, one off the entry hall — which is part of why the layout splits so cleanly between households.
"Does it work as a rental?"
Whether it may be rented short-term is a city question; see below. Whether the floor plan works as one is answered above: three bedrooms of near-equal size, two full baths on the same floor as the bedrooms, and a kitchen that seats people at the island.
"How big is it?"
1,872 square feet, per the Galveston Central Appraisal District. That is the county's figure and it is the only one we quote. The lot is 1,829 square feet, about 0.042 of an acre, from the same record.

The reason we name the source rather than just a number: the eleven labeled rooms on the floor plan add up to one total, a measured plan gives another, and a prior listing may show a third. None of them is wrong. Quoting whichever is largest is how a buyer ends up feeling misled at the appraisal, so the number here will always be the county's. Why the numbers never match.
Floor plan

Every room, measured.

Eleven labeled rooms across two floors. Entry, living room, dining room, kitchen and powder room are down. All three bedrooms and both full baths are up. Note the two staircases: one off the kitchen, one off the entry hall, so the second floor is reachable two ways.

* Square footage and lot size are from the Galveston Central Appraisal District. Year built, roof type and tax rate are from the MLS record; the appraisal district attributes the 1886 build year to the seller rather than to its own records, and taxes without exemptions were $6,572 for 2022. The seller's disclosure marks central air conditioning and central heat without stating fuel type or unit count. Room dimensions are from the listing floor plan and are approximate. Buyer should independently verify all measurements. Why the appraisal district and the floor plan disagree.

Galveston Island

The island questions, answered.

This is not a suburban house and you are not a commuter. Whether you are buying a second home, a rental, or a place to live year-round, these six items decide whether the deal closes. They are answered here in the order they kill contracts.

1. "What about windstorm insurance?"
On Galveston Island, windstorm is a separate policy from flood, usually written through the Texas Windstorm Insurance Association (TWIA), and a missing windstorm certificate is the most common reason an island contract falls apart. Whether this house holds a current WPI-8 Certificate of Compliance: being confirmed. What the record does show: storm shutters, a slate roof of unknown age, and no known roof defects. The seller has never filed a damage claim of any kind other than flood, and has never been paid on a claim without doing the repair. No premium is quoted here; get your own quote from your own agent before you write an offer. On a house of this age the carrier will ask about roof age, electrical, plumbing and foundation before it asks about anything else. What underwriters actually flag on a historic Galveston home.
2. "What flood zone is it in?"
Zone AE. The property sits wholly inside the 100-year floodplain. That is a Special Flood Hazard Area, and it is the single most important fact on this page to underwrite, so it is not buried. The seller's disclosure marks the property as located wholly in a 100-year floodplain, and the 2019 survey carries the same note from the surveyor. With a federally backed mortgage, flood insurance is required here, not optional. AE is the one-percent-annual-chance zone and it comes with a published base flood elevation, which means an elevation certificate can be measured against a real number rather than guessed at.

What the seller discloses alongside that: present flood insurance coverage is in place. No previous flooding from a natural flood event. No previous water penetration into the structure from a natural flood. No claim ever filed under the National Flood Insurance Program. No FEMA or Small Business Administration flood assistance ever received. A house that has been standing on this corner since 1886 with none of those answers is worth more than a favorable zone letter on a newer build.

The specifics, so you can hand them to an insurer today: Zone AE, FEMA panel 48167C0441G, effective 15 August 2019, inside the Special Flood Hazard Area, community of Galveston. The parcel is not within 250 feet of a different flood zone, so there is no boundary argument to have with an underwriter and no obvious exposure to the line moving at the next map revision. Whether an elevation certificate exists for the structure: pending. On a pier-and-beam house in AE that certificate moves the premium more than anything else on this page, so get a real quote during your option period rather than an estimate. What Zone X, X500 and AE actually cost you on the island.
3. "Can I rent it short-term?"
The rules changed in January 2026, and they are stricter than the ones most listings still describe. The City of Galveston now regulates short-term rentals directly, having taken that authority from the Park Board. A short-term rental is any residential dwelling, or part of one, rented for fewer than thirty consecutive days.

What operating one now takes: annual registration at $250 per property, due 31 December, with a $500 late fee after that. A designated local contact reachable around the clock who can physically reach the property in roughly thirty to sixty minutes. Occupancy capped against bedroom count and the property's sewer capacity. Generally one off-street parking space per bedroom. Required guest information posted inside, flood-evacuation guidance included. Lodging tax runs 15% in total — 6% state, 9% local — on top of the fee. Airbnb and VRBO now have to display a valid Galveston Vacation Rental registration number and pull listings without one. Three violations at one property inside twelve months revokes the license.

Short-term rentals are permitted in every zoning district on the island except R-0. This parcel's classification is being confirmed with the city rather than assumed from the block: pending.

Read the parking requirement carefully before you underwrite rental income here. The city generally wants one off-street space per bedroom, which is three for this house. What conveys is a one-half undivided interest in a two-car garage and driveway shared with the house next door. If you are buying this as a short-term rental, settle that with the city in writing first, because it is the part of the ordinance this property is least likely to satisfy. Then underwrite against the full 15%, the annual fee and a real local-contact arrangement, not a nightly rate off a listing site. The 2026 rules in full.
4. "Is it in a historic district?"
Yes. Lost Bayou, one of Galveston's four locally designated districts, alongside East End, Silk Stocking and Strand/Mechanic. The house also carries a historic designation of its own: the seller's disclosure marks both "located in historic district" and "historic property designation", and the MLS record lists historic restrictions on the parcel. One thing is still open: where the parcel sits in the district's own grading — Contributing, Compatible, Non-Contributing or Intrusion — which is being confirmed with Development Services: pending. That matters for the tax freeze further down rather than for the review rules, which apply either way.

Here is what the designation actually means. The Landmark Commission reviews exterior work — additions, demolition, new construction, window and door replacement, anything visible from the street. Interiors are never reviewed, so a kitchen or a floor plan is yours to change with an ordinary building permit. Minor repairs, most fencing and rear decks are handled by staff at the permit counter rather than at a hearing. A full review runs four to six weeks, because the city notifies surrounding owners first, and the Commission meets the first and third Monday of the month. Plan exterior work around that calendar rather than discovering it afterward. What the Commission does and does not review.

The same designation carries an incentive that rarely reaches a listing: put at least 50% of the building's pre-improvement value into a qualifying rehabilitation, have the Commission and City Council approve it, and the City of Galveston freezes its portion of the property tax at the pre-improvement value for ten years. County and school district taxes keep billing on the new value. It applies to buildings classified Contributing or Compatible, and to individually designated Galveston Landmarks — and the seller has already disclosed a historic property designation on this one, which is the door into the program. How the tax freeze works.
5. "What are the taxes?"
2.0161%, and no MUD, PID or LID. Water and sewer come from the City of Galveston, so there is no utility district riding on top of the bill, and the property is not in a groundwater conservation or subsidence district either.

The part that catches buyers: the current owner claims both a homestead and an over-65 exemption, and neither of those transfers to you. Underwrite the unexempted figure, which the tax record puts at $6,572 for 2022, not whatever the current owner is paying. Ask your lender to escrow against the unexempted number in year one. What a MUD, PID or LID actually costs you.
6. "Where do I park?"
One bay of a shared garage on the alley, and a shared drive. Nothing is attached to the house. The detached structure at the back is a two-car footprint, roughly twenty feet square on the survey, and it is split down the middle: each of the two houses owns half. The seller discloses it as "one half of a 2 car garage and driveway", co-owned in undivided interest, and the survey draws the structure at the south property line rather than inside it. Each half measures roughly ten feet wide by twenty deep, which is why the listing calls it a golf-cart garage. A cart fits with room to spare. A full-size truck does not.

A garage on the alley is the island's oldest building pattern, not a workaround. Galveston was platted in 1838 with fourteen narrow lots to a block and twenty-foot alleys running down the middle of each one. Carriage houses, stables, quarters and later garages have filled those alleys and back lots since the city's first decades — enough of them that they have their own scholarly history in Ellen Beasley's The Alleys and Back Buildings of Galveston, and the city's historic design standards treat garages and alley houses as their own regulated building type. That twenty-foot alley is on the 2019 survey, running behind this lot. The lot is also a corner, so there is street frontage on two sides.

Worth knowing if the bay sounds small: golf carts are street legal in Galveston on roads posted at 35 mph or less with no more than two lanes each way, once the cart is registered, inspected and plated with the city. Whether that half-interest is recorded, and how the two households actually divide it, is being confirmed: pending. If you are counting on three off-street spaces for a rental, read the short-term rental answer above first.
The block this house stands on

A house older than the district that grew up around it.

Before the storm, before the seawall, before the district had a name, there was Hitchcock's Bayou — a brackish inlet that once cut inland from the Gulf between 20th and 23rd Streets. This house was built in 1886, when that bayou still ran open water a few blocks from the front door.

Galveston filled the bayou in during the grade-raising that followed the Great Storm of 1900 — the deadliest natural disaster in U.S. history, and the reason nearly 2,000 buildings on this side of the island were jacked up by hand, block by block, between 1904 and 1911, while a 17-foot concrete seawall went in along the Gulf. A house built in 1886, standing in the raised zone, almost certainly went through that lift along with its neighbors — it's part of why a 140-year-old house on this block is still standing square today. The engineering held: when the next major hurricane hit in 1915, the seawall and the raised grade held with it, and the island lost 8 lives instead of the thousands it lost in 1900.

The neighborhood that grew back over that filled-in bayou took the name Lost Bayou. Locally designated a historic district in 1994 and expanded in 2004, it was individually added to the National Register of Historic Places in 2017 — 23 blocks of modest, well-built Victorian and early 20th-century homes between Broadway and Avenue M½, originally home to the working families who rebuilt this stretch of the island by hand. This house predates the district's name, the seawall, and the storm that caused both.
