As-Built Plans & Regularisation in SA: How to Legalise Existing Additions (and Protect Your Sale)

As-Built Plans & Regularisation in SA: How to Legalise Existing Additions (and Protect Your Sale)

When you need this

  • You built a room/patio/garage without approved plans.

  • The bank or purchaser requests proof the house matches the drawings.

  • You’re preparing for sale, valuation or bond approval and paperwork must match reality.

What “as-built” actually means

A measured drawing of what exists today, turned into a professional set that the council can assess. If work was done without approval, we prepare a regularisation submission to bring it into the legal record.

How CasaPlans gets you compliant

  1. Measure-up & photos — We document the house and additions thoroughly.

  2. As-built CAD/BIM set — Accurate plans/elevations/sections of the existing.

  3. Compliance review — Check setbacks, coverage and any contraventions.

  4. Rectification design (if needed) — Small tweaks to meet rules without gutting the design.

  5. Regularisation submission — Complete pack + forms, tracked through council.

Why act now (not when you list)

  • Avoid last-minute panic: Sales often hit delays when paperwork doesn’t match.

  • Protect valuation: Clear records strengthen bond and insurance conversations.

  • Plan future work: Once legal, extensions become simpler.

Costs & timelines (what influences them)

  • Size/complexity of the addition; how much needs rectifying.

  • Whether a structural or energy specialist must be appointed.

  • Council/estate queue time. We reduce delays with complete packs.

What you’ll receive

  • Measured as-built drawings (PDF + editable files).

  • A clear compliance report and recommendations.

  • A lodged regularisation pack with tracking and responses to queries.
