Locate the property before searching permits. Inside San Antonio or another incorporated city, begin with that municipality's building and code systems. For unincorporated property, current County guidance directs Fire Marshal building permits to structures or uses outside the County's defined single-family-dwelling category. The absence of that particular permit is therefore not automatically an open defect for a qualifying home. Separate approvals may still apply to floodplain work, onsite sewage, driveways, manufactured homes, drainage, platting, or other regulated development. Use the deed, parcel, boundary, and exact address to choose each office and ask what record applies.
Treat water issues separately. Bexar County administers floodplain development permits in applicable unincorporated areas and regulates onsite sewage facilities through its published program. Keep flood maps, elevation certificates, drainage studies, claims, photographs, and repair invoices. For septic, collect the authorization, design, maintenance agreement, service reports, and repair history. A mapped floodplain does not prove water entered the house, and a nearby sewer line does not prove this parcel is connected. Confirm the actual service and responsible authority before budgeting a correction.
Now compare the effort each option would require from you, not just the price. A listing could require jurisdiction research, permit follow-up, septic or drainage work, cleanup, showings, inspection negotiations, and months of taxes, insurance, utilities, and loan payments. An as-is contract may reduce some preparation, but examine inspections, termination rights, title conditions, costs, closing date, possession, and any remaining belongings. Estates, co-owners, and tenants need early coordination. The useful next step is not a countywide repair checklist; it is a written plan for the specific office, system, and condition tied to the parcel.
