Confirm municipal, ETJ, or unincorporated status using the parcel and legal description. A city property uses its building and code offices. McLennan County Engineering provides development orders, floodplain information, culvert requirements, subdivision materials, and residential requirements for certain construction outside a city ETJ. If the tract was divided, retrieve the recorded plat or the County exemption affidavit. County guidance notes that an OSSF application can require one of those records, so land history and wastewater review may connect. Retain the recorded instrument reference.
Gather the onsite sewage design, authorization, inspection, final, maintenance, and repair records from the Waco-McLennan County Public Health District program. For floodplain questions, use the County’s property-specific information and permit rather than drawing conclusions from a creek or reservoir reference. Add elevation data, drainage work, claims, photographs, and repair history. Manufactured-home infrastructure, driveway culverts, utilities, access easements, and private-road responsibilities can have separate engineering or recorded documents.
A listing may require plat or affidavit work, OSSF service, floodplain research, repairs, hauling, mowing, photography, appointments, and ongoing tax, insurance, utility, and access costs. A no-obligation cash offer might reduce preparation, but review the diligence and termination windows, earnest money, proof of funds, title and survey requirements, fees, closing date, possession, and contents. Ask how a missing plat exemption or septic final changes the written proposal. Compare the written net and dependable closing date with the County, city, and property tasks left to you.
