General Requirements
A permit is required for any man-made change to improved or unimproved real estate, including buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials. A residential development permit must be obtained before building or adding any man-made structure or adding onto an existing structure. A residential development permit is also needed to obtain electric service for the structure. An elevation certificate is required before permits can be purchased when building in the floodplain. OSSF permits are required for septic installation or modification under county and state rules. Commercial development permits require Fire Marshal plan review first. A 911 address permit is required to establish a new physical address. Right-of-way permits are separately required where applicable.
Required Documents
- County fillable permit application
- Floodplain elevation certificate where applicable
- For commercial work: Fire Marshal plan review completion
- OSSF plans for septic review
- Addressing and site information as required on the county forms
- For water wells: registration permit through the Lower Trinity Groundwater Conservation District
- Permit validity
- Residential development permit: good for two years from the date of purchase. The fillable permit application form states permit expires one year from the issue date unless revoked. Confirm the applicable expiration period with the Permit Department for the specific permit being requested.
- Building code
- No countywide adopted building code for ordinary construction was identified on the reviewed Polk County permit pages. The Permit Office profile ties county permitting to the Flood Damage Prevention Order, National Flood Insurance Program requirements, and OSSF rules under Texas Health and Safety Code Chapter 366 and 30 Texas Administrative Code Chapter 285. The Fire Marshal page states all new commercial buildings must be inspected and comply with NFPA 101, 2021 edition, and NFPA 1 fire life safety codes.
- Owner-builder
- The county application authorizes county entry for lot and land evaluation, septic inspections, and flood hazard evaluation. The county page states deed restrictions remain the property owner's responsibility. For residential work in unincorporated areas, project-specific legal review may be warranted on any Texas HB 2833 private-inspection issues because Polk County publishes development and floodplain controls but does not publicly present itself as a full municipal-style building code department.
- Contractor requirements
- No countywide local contractor registration program was identified on the permit page. The public record reviewed does not show Polk County adopting a broad county contractor-licensing regime for ordinary building permits.

- $35.00 (911 addressing); $150.00 (residential development); $300.00 (residential septic); $150.00 (residential septic repair)
