Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesDelta County, TX
Zoning & raw-land occupancy
Generally allowedDelta County has no general zoning authority over unincorporated land, a state-level limitation on all Texas counties; incorporated towns like Cooper set their own rules, not confirmed for any specific town.
Dwellings, tiny homes & RVs
Unclear - verifyNo county rule on minimum dwelling size, tiny homes, or RV occupancy was found; confirm with Delta County Development Services.
Building permits & codes
Unclear - verifyNo Delta County page describing a general building-permit process or adopted building code was found; ask the county directly before assuming either way. source
Septic & composting toilets
Generally allowedDelta County requires its own OSSF permit, enforcing TCEQ's Chapter 285 state rules, including site evaluation and staged inspections. source
Greywater reuse
Unclear - verifyNo county-specific greywater rule found; it would default to the state TCEQ Chapter 285 framework.
Rainwater harvesting
Generally allowedNo Delta County restriction on rainwater harvesting was found, so the state's generally permissive stance applies by default.
Private wells & water rights
Varies locallyDelta County doesn't appear to have a confirmed Groundwater Conservation District, so the state's default rule of capture likely applies; verify current status with TWDB. source
Living disconnected from utilities
Generally allowedNo county ordinance requiring utility hookup was found, and the county's own OSSF materials describe septic as the standard solution where centralized sewer isn't available.
