Plot Plan & Site Plan Surveys in Los Angeles & Ventura County

What a Plot Plan / Site Plan Survey Shows

A plot plan or site plan survey is a 2D measuredsite map showing buildings, hardscape, fences, walls, driveways, and othervisible improvements on a property. It is commonly requested for permitsubmittals, remodel planning, ADU feasibility, and as a base map forarchitectural and design work. Unlike a topographic survey, a plot plantypically does not include ground elevations or contours, it focuses on theplanimetric (horizontal) layout of improvements. Plot plans are often combinedwith boundary work so the deliverable includes property lines, setbackdimensions, and tie-ins your design team can rely on.

Common Reasons Clients Request a Plot Plan Survey

• Permit  submittals requiring a site plan or plot plan showing existing improvements.

• Remodel and addition planning where the architect needs an  accurate base map.

• ADU feasibility analysis to confirm available buildable area  and setbacks.

• Property line questions where corners and improvements need  to be shown together.

• Pool, hardscape, or fence permits requiring site  documentation.

• Pre-purchase due diligence to understand site configuration  before closing.

• Insurance documentation of existing improvements.

• Compliance documentation when an agency requests an  existing-conditions site plan.

What’s Included in a Plot Plan Survey

• Field  location of visible improvements: buildings, garages, sheds, walls, fences,  and driveways.

• Hardscape features: patios, walkways, pool decks, and  retaining walls.

• Vegetation when relevant: significant trees, hedges, and  landscape boundaries.

• Property lines and corners when combined boundary scope is  included.

• Setback dimensions and offsets to property lines.

• Visible utility features: meters, cleanouts, transformers,  and fire hydrants near the site.

• 2D site map deliverable (PDF) ready for permit submittal or  design coordination.

• CAD-ready deliverable (DWG/DXF) when needed for design team  use.

Common Plot Plan Survey Add-Ons

• Boundary  Survey, almost always recommended for plot plans, since your designer needs  property lines.

• Topographic Survey, when grading, drainage, or elevation  matters for the project.

• As-Built Survey, when existing building dimensions and  detail are needed.

• Floor Plan Survey, when interior layout documentation is  required.

What We Need to Start Your Plot Plan Survey

• Property  address, and APN if available.

• Purpose of the plot plan: permit submittal, remodel  planning, ADU, pool, fence, and so on.

• Scope: which improvements need to be shown, and the level of  detail required.

• Required deliverable format: PDF for permit submittal, CAD  for design coordination.

• Permit agency requirements when applicable, since some  agencies require specific information on plot plans.

• Any available plans or sketches, helpful but not required.

• Access details: occupancy, gate or lock access, and  restricted areas.

Our Plot Plan Survey Process

1. Scope  confirmation. We confirm which improvements need to be shown, the deliverable  format, and whether boundary is included.

2. Records research. We pull parcel maps, prior surveys, and  applicable records to support boundary work when it is included.

3. Field work. Our crew locates improvements, hardscape, and  visible features within the agreed scope.

4. Mapping. We compile the 2D site map and add property lines,  setback dimensions, and required notes.

5. Quality check and delivery. We review the deliverable,  stamp and sign when required, and deliver in your requested format.

Plot Plan / Site Plan Survey Deliverables

• CAD file (DWG/DXF) for design team use when included in  scope.

• Property lines and corners when combined boundary scope is  requested.

• Setback and improvement dimensions called out on the map.

• Notes and legend appropriate to the deliverable purpose.
