SANDOVAL ADU
Rendering of a one-story ADU with a black standing-seam gable roof, white stucco walls and a recessed cedar porch

ADU design and drafting in Los Angeles.

Floor plans, permit drawings and photoreal renderings for backyard units, garage conversions and two-story ADUs. Every project starts as one accurate 3D model, so the plans, sections and renderings always agree.

For homeowners, builders and designers
01

ADU floor plans

Layouts for detached ADUs, junior ADUs and garage conversions, sized to your lot and setbacks.

02

Site plan, floor plan, roof plan, elevations, sections and schedules, drawn in Revit from one model.

03

Photoreal renderings

Exterior and interior views rendered in Blender with real materials, light and landscaping.

04

06

CAD and Revit files

Every job delivered as a combined PDF set plus the native RVT and DWG files.

Structural engineering and Title 24 energy reports are prepared by licensed consultants when a project needs them.

04Process

How a plan set gets made
  1. 01

    Intake

    Site measurements or survey, your wish list, and your city's ADU rules checked before drawing starts.

  2. 02

    Model from a standard template

    Every ADU starts from the same Revit template: title block, wall types, door and window families, sheet list.

  3. 03

    Sheets come from the model

    Plans, elevations and sections are views of one model, so a change on one sheet updates every sheet.

  4. 04

    Checklist review

    Setbacks, heights, egress windows, areas and dimensions checked against a written list before anything goes out.

  5. 05

    Renderings if you want them

    Photoreal views and rendered plans from the same dimensions, for clients, lenders or HOA review.

  6. 06

    Delivery

    One combined PDF set plus the native files, ready for engineering and plan check.

05About

Andrew Sandoval
Interior rendering with pendant lights and a vaulted ceiling

I'm Andrew Sandoval, an ADU designer and drafter in Los Angeles. I build every project as a 3D model first, then draw the plans and render the views from that same model, so what a homeowner sees in a rendering matches what the city sees on the plans.

I work directly with homeowners, and as drafting support for designers and builders who need more sets done each week.
