When Do You Need As-Built Drawings?
California homeowners and property owners need professional as-built plans in several critical situations. Here is when accurate documentation saves you time and money.
- Before Any Remodeling or Renovation Project
California building departments require as-built drawings showing existing conditions before approving remodeling permits. Without accurate as-built plans, your permit application will be rejected. - Homes Without Original Construction Plans
Many older California homes have no existing plans on file. Our as-built survey creates professional documentation from scratch, measuring every wall, window, door, and structural element. - Unpermitted Work or Undocumented Changes
Previous owners made changes without permits? As-built drawings document the current reality of your property, the essential first step to legalizing existing work or planning new improvements. - Real Estate Transactions & Insurance
Accurate as-built documentation protects your investment during property sales, refinancing, or insurance claims. Lenders and insurers increasingly require current as-built floor plans. - ADU, Addition, or Expansion Planning
Planning an ADU, room addition, or home expansion? As-built drawings of your existing property are required before any new construction can be designed or permitted in California.
