As-Built Drawings

Existing-structure Field Survey + CAD As-builts for permits, remodels, additions, ADUs, and buyer/lender documentation across Southern California.

As-built drawings are the starting point for any remodel, addition, or renovation project. In Southern California, an accurate record of existing conditions is vital for obtaining building permits. We conduct thorough on-site field surveys to measure the building's interior/exterior structure, spatial layout, and key utilities, then translate that data into high-precision AutoCAD drawings. Whether you are planning a garage conversion, an ADU addition, or a commercial space renovation in Los Angeles, Orange, San Bernardino, or Riverside County, our as-built services ensure your design is based on real-world data, preventing errors and construction delays.

What’s included in an As-Built services?

Based on general building permit requirements in Southern California, we provide the following building-specific plans (excluding land surveying/site plans):

Existing Floor Plans

Clearly showing room layouts, wall thicknesses, door/window locations, and existing kitchen/bath fixtures.

Existing Exterior Elevations

Drawings of all four sides of the house, including real height dimensions and window proportions.

Existing Roof Plan

Documentation of the roof shape, slope directions, and the locations of existing chimneys or skylights.

Utility Locations

Accurate marking of the electrical panel, water meter, and gas meter to provide a reference for your future additions.

Structural Details

Records of actual ceiling heights and visible beam locations, so you know exactly how much space you have to work with for your remodel.

How does the As-Built process work?

We follow five simple steps to prepare the foundational drawings required for your project:

Free Consultation & Scheduling

We discuss your project details, provide a clear quote, and schedule a time for the on-site measurement.

On-Site Measurement

We visit the property in person to measure every wall, every room, and the heights of all doors, windows, and ceilings.

Utility Mapping

We locate and mark the exact positions of the electrical panel, water meter, and gas meter on the plans to help you plan your utility lines.

AutoCAD Drafting

We take the data collected on-site and draw it into standard AutoCAD plans, ensuring they are ready for your designer or for submission to the city.

Final Delivery

We send the final AutoCAD (DWG) files and high-resolution PDF copies directly to you.
