Buying a Short-Term Rental Near Canyon Lake: What to Check First

If you’re buying near Canyon Lake with short-term rental income in mind, check five things before you fall for the view: the deed restrictions and POA rules, which local rules apply at that exact address, how hotel taxes will be collected, whether your insurance covers paying guests, and whether the septic system fits the number of people you plan to host. Then plan for the lake’s seasons and water levels.

Here’s what each check involves and who to ask.

Private restrictions and local rules

Deed restrictions and POA rules

Private restrictions can limit or block rentals no matter what any government allows, so read them first. Look for minimum lease terms, “residential use” language, bans on commercial use, occupancy or parking limits, and any amendments.

If the home is in a property owners’ association, Texas Property Code Section 207.003 requires the association to deliver a resale certificate and current copies of the restrictions, bylaws and rules within 10 business days of a written request. Ask for them early, while you can still walk away, and have a real estate attorney review them if rental income is central to your plan.

Which local rules apply

Start by confirming whether the property is inside a city’s limits.

Inside a city. City rules can be strict. The City of New Braunfels’ short-term rental guide says its ordinance does not allow short-term rental use in residential zoning districts, so a residential property needs a zoning change and a special use permit, which the guide calls a discretionary City Council decision. Its permit checklist includes $500,000 per occurrence in commercial liability insurance, a fire inspection and a city hotel tax account. Confirm the current rules with the city before you rely on them.

Outside city limits in Comal County. The county touchpoints are practical ones. The county’s permits page shows the Engineer’s Office issuing septic (OSSF) and floodplain development permits. The Fire Marshal posts burn bans for unincorporated areas, and while one is on, campfires, fire pits, fire rings and chimineas are prohibited. Ask the county whether anything else applies to your plans.

Next to the lake. Corps of Engineers rules apply to your guests, too. The Corps’ adjacent landowner rules bar private exclusive use of public land, signs that limit public access, fireworks, and vehicles (golf carts included) anywhere but paved roads and authorized access points. The Corps FAQ also rules out private docks. Don’t market the public shoreline as a private yard or promise a dock.

Hotel occupancy tax: state and local layers

State tax. The Texas Comptroller collects a 6 percent state hotel occupancy tax, and it applies to houses, not just hotels. The Comptroller’s FAQ defines a short-term rental as a stay of 29 days or less.

If a booking platform has agreed to collect and remit state tax on your behalf, it handles those bookings. For direct bookings or platforms that don’t collect, you collect and remit it yourself, starting with Form AP-102, the Hotel Occupancy Tax Questionnaire. The Comptroller’s hotel tax line is 800-252-1385.

Local taxes. Cities, some counties and special purpose districts can add their own hotel taxes, and the Comptroller tells owners to contact the city and county directly.

WORD. Around Canyon Lake, the Water Oriented Recreation District (WORD) of Comal County requires a permit for tourism businesses, including lodging of less than 30 consecutive days, according to its business FAQ. The permit is free for first-time applicants and returns are filed quarterly.

WORD’s 2025 tax return form lists lodging at 3 percent. Its instructions say owners who book through a third party still file, and a return is due every quarter even when no tax is owed. Check the district map to see whether an address falls inside WORD.

Tax rules change, so confirm with the Comptroller and WORD, and talk with a tax professional about your situation.

Insurance: don’t assume you’re covered

The Texas Department of Insurance warns that homeowners insurance probably won’t cover the costs if a short-term guest gets hurt or causes damage. It suggests asking your insurer about coverage for paying guests, notes that some home-share platforms sell coverage, and says landlord insurance is mainly for long-term leases and may not suit short-term rentals.

Flood is separate. FEMA notes that most homeowners insurance doesn’t cover flood damage and that a new flood policy typically has a 30-day waiting period. Get quotes while you can still back out of the contract.

Septic: match the system to your plan

If the home is on a septic system, called an on-site sewage facility (OSSF) in Texas rules, find out what it was designed to handle. State rules require a permit to construct, alter, repair, extend or operate one, and permits transfer to a new owner automatically at sale.

The definition of altering a system includes increasing the volume of permitted flow or changing the nature of what goes into it. So ask the Comal County Engineer’s Office for the permit file and compare the design with the guest count you plan to advertise. If you plan to add bedrooms or sleeping space, ask whether that triggers a new permit.

Maintenance is the next question. Comal County lets owners of single-family homes maintain their own aerobic systems, but commercial owners must use licensed providers. Ask how the county would classify a home used as a short-term rental.

Close to the lake, the Corps won’t allow septic tanks below the 948-foot contour. Systems in a federal flowage easement need Corps consent, must use spray fields, and must keep spray zones at least 75 feet from the 940-foot contour.

Seasons, burn bans and the water level

Lake recreation here follows the calendar. WORD’s Canyon Park and Comal Park are open March through October, and the Corps closes some campsites at Potters Creek Park from October 1 through the end of March.

The water level matters too. The Corps notes that some boat ramps close when the lake is too low, and the Texas Water Development Board’s daily record shows the lake stayed below its normal 909-foot level from late 2021 until July 2026. Burn bans can also take a fire pit off your amenity list while they’re in effect.

I don’t publish occupancy or nightly rate figures because they change quickly, but I can pull current numbers for your area.

Your pre-offer checklist

1. Request the deed restrictions and, if there’s a POA, the resale certificate, bylaws and rules.
2. Confirm whether the address is inside city limits, and if it is, read that city’s rental rules.
3. Check the WORD district map and plan for the WORD permit.
4. Decide how state hotel tax will be handled for each booking channel.
5. Get short-term rental liability and flood insurance quotes.
6. Pull the OSSF permit file and compare it with your planned guest count.
7. Find the Corps boundary and any flowage easement on the survey.
8. Budget for the off-season, burn bans and low-water stretches.

If you’re weighing a rental purchase

A short-term rental plan works only when the restrictions, the taxes, the insurance and the septic all line up for that specific property. If you’d like help running an address through this list, send me a note.
