Before you write an offer on a parcel, ask one question: what can legally be built here, and who confirms it in writing? Get the plat, survey, and title commitment first. Then get a written utility letter or septic evaluation, plus floodplain and permit answers from the county or city.
What should buyers verify before buying land near Lake Conroe?
Choosing Lake Conroe land starts with proof, not a listing label. Verify legal recorded access, written water and sewer availability for the specific address (or a septic feasibility evaluation), floodplain status, drainage, deed restrictions, and which permits your plans require. A parcel can look buildable and still fail one of those checks.
Key Takeaways
- In unincorporated Montgomery County, floodplain review applies to property within 100 feet of the floodplain or floodway, so a building site outside the mapped floodplain can still be reviewed.
- Structures in or within 100 feet of the Area of Special Flood Hazard must be elevated at least 2 feet above Base Flood Elevation, verified by an elevation certificate from a licensed surveyor or engineer.
- The county asks for a utility-district letter dated within the past year stating that water and sewer will be provided to the specific address, and a letter that only confirms capacity is not enough.
- A parcel within 2,075 feet of Lake Conroe may need a San Jacinto River Authority permit as proof of sewer when that requirement applies.
- If the parcel needs a septic system, a new system requires a permit, so confirm a buildable septic area before you commit.
Access, utilities, drainage, and the right to build change from one parcel to the next. That is true whether you plan to build soon or hold the land for later. Here is how I walk buyers through each check.
What should you verify first when choosing Lake Conroe land?
Start with jurisdiction and recorded access. The parcel’s location decides which rules and permit office apply, and a road you can drive on is not proof that you have a legal right to use it.
Which jurisdiction governs the parcel?
Lake Conroe-area parcels may sit in the City of Conroe, another municipality, or unincorporated Montgomery County. The permitting authority and the development rules follow that line. Verify the city limits and county precinct before you rely on any guidance, including the county rules in this post.
In unincorporated Montgomery County, a development permit is generally required for proposed development. That includes construction, grading, dredging, clearing, and filling. Don’t plan to clear the lot just to see what you have before you know what approval applies.
Is access legal, recorded, and maintained?
Legal access means a recorded right to reach the lot from a public road. Ask for the recorded deed, survey, subdivision plat, title commitment, and every easement they reference. Your title company can pull the commitment. (My post on buyer closing costs in Lake Conroe, line by line shows where that fits in the closing process.)
A subdivision plat must identify each lot’s size and intended use and show roads and utility rights-of-way. Compare the plat, deed, survey, and commitment against each other. Don’t rely on a listing description or a casual “yes, it has access.”
Then ask who maintains the road:
- Is it publicly maintained?
- Is it privately maintained?
- Is it covered by a road-maintenance agreement?
In my experience, the surprises usually come from the paperwork around a lot, not the lot itself.
What do deed restrictions and easements limit?
Deed restrictions, utility easements, drainage easements, and subdivision or lake-related rules can all limit what you build and where. Read them before you make an offer, not after. Also confirm whether the parcel has usable lake access. Shoreline access can be private, restricted, or unavailable, and a lake view does not guarantee a right to the water. If the shoreline is part of your plan, my post on waterfront homes in Lake Conroe and who to trust is worth your time.
Can you get water, sewer, or a septic system on the parcel?
Only written confirmation for that specific address answers it. A water or sewer line down the road does not.
Montgomery County’s residential guidance requires a letter on utility-district letterhead, dated within the past year, stating that water and sewer will be provided to the specific address. A statement that capacity exists is not sufficient. The same guidance says that if the property is within 2,075 feet of Lake Conroe, a San Jacinto River Authority permit is required as proof of sewer when applicable.
Don’t assume that distance applies or doesn’t apply from a listing map. Confirm the measurement and the requirement for your parcel with the county or the authority.
What if there is no sewer?
No sewer does not mean unbuildable, but it adds a separate approval path. Constructing a new on-site sewage facility requires a residential septic permit, so you want to know a system can be permitted before you close.
Acreage alone does not prove feasibility. County planning materials for larger proposals must address the floodplain, soils, topography, water wells, easements, and drainage, and those materials come from a professional engineer or registered sanitarian. On a single lot, the same factors still decide where a system can go.
Hire a licensed septic professional to evaluate soils, setbacks, the reserve area, driveway placement, and floodplain constraints on your footprint. The county’s development regulations also prohibit septic-tank drainage into public roads, streets, alleys, or other public ditches. That limits where the system can sit.
How do floodplain and drainage affect what you can build?
They can decide whether you build and how high. Floodplain rules apply even when your building site looks dry.
Work within the 100-year floodplain requires a permit, and floodplain review is required for property located within 100 feet of the floodplain or floodway. The county’s residential process also requires a separate permit for each structure or addition. For this purpose a structure is anything with a roof and at least one wall, including a carport. That matters if you plan a home, a garage, and a shop.
Structures placed or built in, or within 100 feet of, the Area of Special Flood Hazard must be elevated at least 2 feet above the Base Flood Elevation. A licensed surveyor or engineer provides the elevation certificate that verifies compliance. Check FEMA and county floodplain information first. Then have a surveyor or engineer confirm elevation and buildable-area issues on your site.
Why check drainage before clearing or filling?
Clearing and filling change where water goes, and the county treats drainage as an engineering issue. For subdivision developments subject to platting, the regulations require a complete drainage plan prepared and sealed by a Texas-licensed professional engineer. Alterations in a floodway may need FEMA approval before the county approves a drainage plan or study.
Ask how water crosses the parcel and what drainage easements exist. Do that before you buy, not after the first heavy rain.
What order should you run these checks in before your contract deadlines pass?
Run documents first, then utilities or septic, then flood and survey questions, then permits and restrictions. A listing’s “buildable” label is not an approval, and each step below can show you early that a parcel won’t work as planned.
- Get the recorded deed, survey, plat, title commitment, and all referenced easements.
- Confirm access is legally recorded and identify who maintains the road.
- Ask the water and sewer provider for written availability to the specific address.
- If sewer is unavailable, get a licensed septic evaluation.
- Check FEMA and county floodplain information, then have a surveyor or engineer confirm elevation and buildable area.
- Ask the county or city whether your plan needs a development, floodplain, driveway, septic, or other permit. List every item: clearing, driveway, fill, grading, dock, home, or outbuilding.
- Review deed restrictions, association documents, utility easements, drainage easements, and any lake or subdivision rules.
| What to verify | Who confirms it | What to ask for |
|---|---|---|
| Legal access | Title company and recorded records | Deed, plat, survey, title commitment |
| Road maintenance | Seller, recorded records, county | Maintenance agreement or road records |
| Water and sewer | Utility district, San Jacinto River Authority when applicable | Letter naming the specific address, dated within the past year |
| Septic feasibility | Licensed septic professional and county | Soil and site evaluation, septic permit path |
| Floodplain and elevation | FEMA and county information, surveyor or engineer | Elevation certificate where required |
| Drainage | Licensed engineer, county | Drainage plan or study where required |
| Permits | County or city | Written answer on each planned structure and site work |
| Restrictions and easements | Title commitment, association, recorded documents | Full restrictions and easement documents |
If you’re holding land for later, run the same checks now. They show what the parcel can become, which matters when you are weighing it as an investment. My post on Lake Conroe land opportunities for investors in 2026 pairs well with this checklist.
Your answers depend on the parcel, your plans, and your timeline. The final determination comes from the governing authority and qualified survey, engineering, and septic professionals. I help buyers line up those pieces before they commit, so the contract deadlines work for you.

FAQ
Can I clear, grade, or fill a Lake Conroe lot before getting county approval?
No, not in unincorporated Montgomery County without checking first. A development permit is generally required for construction, grading, dredging, clearing, and filling. If the parcel is inside a city, that city’s rules apply instead, so confirm jurisdiction before any site work.
Will my lot need a septic system?
It will if sewer service isn’t provided to your specific address. Ask the utility provider for a written answer. If the answer is no, a licensed septic evaluation tells you whether the soils, setbacks, and reserve area support a permitted system on your building footprint.
How close to the floodplain triggers review?
Within 100 feet of the floodplain or floodway triggers floodplain review in unincorporated Montgomery County. Structures in or within 100 feet of the Area of Special Flood Hazard must be elevated at least 2 feet above Base Flood Elevation. A licensed surveyor or engineer provides the elevation certificate.
Does a lot near Lake Conroe come with lake access?
Not automatically. Shoreline access can be private, restricted, or unavailable. Confirm any lake access rights in the recorded documents and subdivision rules, not from a listing photo or map.
Who confirms that a parcel is buildable?
The governing city or county authority, together with a qualified surveyor, engineer, and septic professional. A listing’s “buildable” label is marketing, not approval. Verify recorded access, utilities, restrictions, floodplain status, drainage, and permits before you commit.
