If you close on a Lake Tyler home in December and the seller never filed this year's septic inspection, who has to fix it? On Lake Tyler and Lake Tyler East, the answer is whoever holds the lease or the deed when the City of Tyler comes to collect. This winter, the City is collecting.
Both lakes supply drinking water. Together they deliver about 30 million gallons a day to Tyler, according to the City's Lake Tyler Updates and Projects page. Every lakefront lot on both lakes therefore has a sanitation file with the City alongside its title or lease. Two deadlines in that file passed on October 1, 2026. Two more fall during the months when many winter listings go under contract and close.
The dates that fall between contract and closing
| Requirement | Deadline | If it's missed |
|---|---|---|
| Boathouse plumbing inspection, for boathouses with plumbing fixtures | October 1, 2026, now past due | The City says it will begin enforcement as provided by ordinance |
| Annual septic inspection report from an OSSF-licensed inspector | October 1, 2026, with a one-time grace period through January 1, 2027 | Lake Tyler: lease renewal withheld. Lake Tyler East: possible $500 fine |
| Documentation of septic repairs found in an inspection | March 2, 2027 | Lake Tyler: lease suspension. Lake Tyler East: fines |
As of the City's last update on October 13, 2026, about half of the boathouses that need a plumbing inspection had been inspected. That leaves a lot of waterfront homes with an open item. Some of them will be listed this winter.
The same requirement carries different consequences on each side of the connecting channel, because the two lakes are owned differently.
On Lake Tyler, the septic report is tied to the lease
Lake Tyler lots on the west side sit on City-owned land under lease. The seller owns the house and the boathouse. The lot underneath belongs to the City. That makes the lease, not the deed, the document that governs the buyer's right to stay on the lot.
The City of Tyler Code of Ordinances, Chapter 19, Article VI, connects the septic report directly to that lease. The annual inspection report is due when the annual lease fee is due. The City "will not process lease renewal payments without the annual inspection report." If an inspection finds problems, the lease holder has 60 days to fix them. After that, the City withholds renewal and reserves the right to begin terminating the lease.
The renewal rules in Section 19-202 explain why that matters. A lessee who doesn't pay rent within 45 days of the due date is notified and given up to 60 days to remove the improvements. If they don't act, the lease becomes void and "the improvements thereon will revert to the City." Because the City won't process a renewal payment without the septic report, a missing report puts the lease's renewal at risk.
The sale itself also runs through the City:
- Approval. Every lease transfer, including a transfer to heirs, needs approval from the Director of Utilities. Approval is "not to be unreasonably withheld."
- Recording. A transfer isn't effective until a copy is filed with the Smith County Clerk's Official Public Records.
- The house price. The City stays out of the sale of the improvements. The seller can sell them "at whatever price the lessee can get."
- Fees. The City's Lakes page lists $150 for a lease transfer, $300 for a transfer by will or devise, $100 for a consent to mortgage, $100 for a lease addendum, and $100 when the City files the document.
- Gaps in the chain. If the City's records show a different lessee than the person selling, the requester has to document every interim transfer and pay the fees for each one.
That last item comes up on inherited lots and on houses that have changed hands informally over the years. A missing septic report and an outdated lessee record are both things to resolve before listing, not during the option period.
Financing involves the City too. Section 19-204 lets a lessee pledge the leasehold and improvements as loan collateral once the Director of Utilities consents. That consent is the $100 fee on the list above.
On Lake Tyler East, ownership is private but the City still checks sanitation
On Lake Tyler East, buyers receive a deed. The City says it does not own the residential lots there. It does hold a sanitary control easement that runs 100 feet back from the 378-foot elevation line, and it is responsible for the lake's water quality. A Smith County court document known as Exhibit B sets out what owners are responsible for.
Under paragraph (u) of Exhibit B, a new owner files their information with the City within 10 days of acquiring the property. Exhibit B sets a $25 registration fee for a five-year term. The City's current Lake Tyler East Registration Form lists an annual registration fee of $5 per waterfront lot, billed in October. A buyer can confirm the current amount with Tyler Water Utilities at (903) 531-1238. Either way, the 10-day window starts at closing.
The septic report on this side is due with the annual registration. If the report and use fee aren't submitted, the owner may face a $500 fine, and the City reserves the right to file a lien on the property for non-payment.
Why boathouse plumbing is getting attention now
Under Section 19-206, no part of a lot's sewage disposal system, "including plumbing fixtures, collection and transport components," may sit within 100 feet of the 378-foot elevation. The annual septic inspection has to cover "all collection/pumping facilities whether over the water or not." The same section bars new sanitary facilities inside that setback after April 11, 2025. Boathouse plumbing approved by City variance before August 19, 2022 may stay in use as a legal non-conforming use, but only under conditions. The system must be engineer-designed. A boathouse is limited to one each of a commode, lavatory, shower or tub, kitchen sink, water heater, and ice maker. Any collection tank needs containment and a leak alarm. The system is subject to routine City inspections and the annual inspection. For a buyer looking at a boathouse with a bathroom or kitchen, the variance and inspection record show whether those fixtures can stay.
The City's inspection program checks those fixtures against City Code. The first inspection is free if everything complies. If corrections are needed, the owner gets time to make them. Owners who haven't scheduled theirs can contact Danielle Koch at Rub-A-Dub Plumbing, (903) 525-6336, or Pam Lee at the City, (903) 426-1143. Completed reports go in through the City's online form.
Boathouses and piers also get a separate annual inspection under Section 19-205. The Director of Utilities can declare a structure below the 378-foot line "unsafe, unsightly or a nuisance" and order it repaired or removed. On these lakes, the boathouse is often one of the most valuable improvements on the lot. Its paperwork deserves the same attention as the house inspection.
The water level and the dam study
The water itself adds to the City's focus. On November 6, 2026, the provisional reading on Water Data for Texas showed Lake Tyler at 82.4% full, 2.87 feet below conservation pool. On August 6 it was 95.1% full. The U.S. Drought Monitor map valid November 3, 2026 showed all of Smith County in drought, with 89.86% of the county in severe drought.
In October, the City approved a $355,905 study by HDR Engineering of the Lake Tyler East Dam. The study compares spillway rehabilitation with embankment improvements, and it was prompted by sinkholes and possible seepage found in late summer and fall 2025. The City expects results in spring 2027. The Tyler Morning Telegraph covered the evaluation on October 15.
At the policy level, the City Council adopted an updated Lake Tyler Master Plan on February 25, 2026, the Tyler Morning Telegraph reported. Its priorities include expanded water-quality monitoring, stronger stormwater practices, and targeted shoreline erosion control. KLTV reported that boat registration or day-use fees were among the revenue ideas under consideration, and that no official decisions had been made. Tyler Water Utilities plans a community open house on lake projects in February or March 2027.
All of this points the same way. The City's attention to lot sanitation is part of how it protects its water supply, and sellers should plan on it continuing.
What should be in the file before a listing or an offer
For a seller listing this winter, or a buyer writing an offer, these are the documents worth gathering:
- This year's septic inspection report, completed and signed by a licensed OSSF inspector, with the submission confirmation email the City's form sends.
- Proof that any repairs were documented, or a clear plan to finish them before March 2, 2027.
- The boathouse plumbing inspection result, if the boathouse has plumbing fixtures.
- On Lake Tyler, a current lease, proof that this year's renewal was processed, and a City lessee record that matches the seller's name.
- On Lake Tyler East, the seller's current registration with the City.
- Any Approval for Construction forms and building permits for the boathouse, pier, or additions. On Lake Tyler leased lots, and for any structure over the water on either lake, the code requires approval before construction begins.
A seller who brings items one through five to the listing appointment has answered a buyer's first questions before they're asked. A buyer who requests them during the option period knows what kind of file they're inheriting.
Quick answers
Does a transferred Lake Tyler lease keep its old rent? The code sets rent by when a lease originated. Leases from before November 18, 2011 are CPI-adjusted from a $50 base, with each increase capped at 10%. Leases originating after that date pay the equivalent of City taxes on the City's land value plus the Smith County Appraisal District improvement value. Before closing, a buyer can ask Tyler Water Utilities which calculation will apply to that lease after the transfer.
Can I tear down and rebuild closer to the water? On Lake Tyler leased lots, no building other than boathouses and piers may be built within 100 feet of the 378-foot line. Buildings other than boathouses constructed after April 9, 2025 need a finished floor elevation of at least 380 feet. Approval for Construction costs $250.
How big can a new boathouse be? One boathouse per residential lot. It can be no more than 2,000 square feet, 60 feet wide, or 75% of the lot's shoreline frontage. It generally extends no more than 100 feet from the shoreline, or up to 150 feet where the water is shallower than 5 feet. It's limited to a single story with a roof deck, and its maximum height is 45 feet.
