Zoning, building permits and septic rules in Town of Washington, Louisiana

Rules another office applies inside Town of Washington

Town of Washington does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Septic permitRequired

  Individual sewage system (septic tank with secondary treatment) for a home inside Washington town where no community sewer system is available

  • Applies only where no community sewer system is available; if one is available it must be used (LDH packet step one).
  • Property owner applies with plat, proof of ownership and a 911 address; a sanitarian conducts a site survey before the temporary permit is released.
  • A final permit issues only after installation is verified.

  temporary permit validity: 1 year (extension may be requested from the local sanitarian if the system is not installed within a year)

  “please note that your temporary permit is good for one year”

• Septic inspectionRequired

  Installation of an individual septic system inside Washington town under a state permit

  • No part of the system can be covered until the sanitarian verifies the installation.

  “a sanitarian must complete a final verification on the installation of your septic tank with secondary treatment”

• Mandatory utility hookupSewer (with conditions)

  New home inside Washington town when a community sewer system is available

  • Applies to sewage disposal; a water-connection rule was not located.
  • The town operates water and sewer utilities per its site navigation, but no town connection ordinance was opened.

  “if a community system is available, you must use it for your sewage disposal needs.”
