Summary

Austria’s fossil heating restrictions prohibit new oil heating systems and limit replacements in existing buildings. Compliance is enforced at the permitting stage, making this a market access issue rather than a post-installation fine risk. Building owners must factor heating compliance into renovation planning early to avoid costly redesigns.

  • Progressive tightening toward 2030 climate goals.

Current Status

Restrictions are in force, with enforcement primarily through building permits and renovation approvals.

Penalties for Non-Compliance

  • Refusal of building permits.

  • Orders to remove non-compliant systems.

Examples of Known Violations

  • Installation of oil boilers during renovation without exemption.

  • Misclassification of renovation scope to avoid compliance.
