How are inspections scheduled?
Obtain the applicable Class A or Class B floodplain development permit from Randall County Road and Bridge before construction; floodplain building proposals require surveyor certification, and no work may begin before approval. For OSSF work, submit the application to ehealthOSSF@amarillo.gov, by mail, or in person.

Do not backfill until the system passes inspection. Public OSSF permit records are available in eBridge with username 'public', password 'publicuser', and cabinet 'AMARILLOEH'.
Which codes and exemptions should I review?
Randall County requires a floodplain development permit before construction and applies 44 CFR floodplain requirements and the Randall County Flood Damage Prevention Order. A Class A permit is required for all development outside the mapped 100-year floodplain and a Class B permit for property wholly or partly within it; regulated development includes buildings, excavation, fill, grading, paving, and storage. Residential development is prohibited in an identified floodway. Subdivision development is governed by the county's 2023 subdivision regulations. OSSFs are administered for Randall County by the Amarillo Area Public Health District under 30 TAC Chapter 285 and the county OSSF order. No general county structural building-code edition was published for ordinary unincorporated construction in 2026. No minor-structure, cosmetic-work, or acreage-based county development-permit exemption was published: the county says all development requires either a Class A or Class B permit. For the substantial-improvement calculation only, the floodplain order excludes minimum work needed to correct identified health or safety code violations and qualifying alterations to historic structures; these are not general permit waivers. The OSSF authority notes possible lot-size exceptions for lots platted before January 1, 1988, but still requires approval before installation, repair, replacement, or alteration.
