Measured drawings built on real Los Angeles conditions

In Los Angeles, the difference between a smooth project and a stalled one is often the quality of the existing-condition drawings it started from. The city's housing stock ranges from historic bungalow courts and hillside homes to dense multifamily and modern infill, so no two as-built projects look alike.

Every downstream decision — structural, layout, budget — leans on the base drawings, so getting them field-verified up front pays for itself many times over. The region's building stock spans century-old Craftsman bungalows and Spanish Colonial Revival homes, mid-century hillside residences, dense multifamily buildings, and modern infill. That variety means as-built accuracy matters: assumptions from a template rarely survive contact with a real LA property.

FastAsBuilt combines on-site laser measurement with senior CAD drafting to document existing conditions across Los Angeles and the rest of Los Angeles County. You get clean, dimensioned floor plans, elevations, and sections you can hand straight to your architect, designer, contractor, or the Los Angeles Department of Building and Safety (LADBS).

Why Los Angeles owners order plans

Projects that start with accurate as-builts

Across Los Angeles, the most common reasons property owners come to us are simple: they need drawings that reflect what is really there.

ADUs & garage conversions

Accessory dwelling units are booming in Los Angeles. Precise as-builts of the existing structure are the first thing plan check wants to see.

Additions & remodels

Adding square footage or reworking a floor plan in Los Angeles starts with drawings that match the current building exactly.

Commercial & tenant improvements

Landlords and businesses in Los Angeles need reliable existing-condition drawings for build-outs, change of use, and leasing.

Permit submittals

Additions, ADUs, and tenant improvements in Los Angeles all require accurate as-built drawings for the building department.

Buying & selling

Realtors and owners in Los Angeles use measured floor plans and verified square footage to market and close with confidence.

Insurance & records

Accurate documentation of your Los Angeles property protects you for insurance, appraisals, and future planning.

Permitting in Los Angeles

Drawings the Los Angeles Department of Building and Safety (LADBS) will accept

Los Angeles County is one of the most permit-intensive jurisdictions in the country. Most cities require accurate existing-condition drawings before they will accept plans for additions, ADUs, tenant improvements, or change-of-use projects, and the City of Los Angeles Department of Building and Safety (LADBS) is especially rigorous about matching submitted drawings to what is actually on site.

In Los Angeles, plans for additions, accessory dwelling units, and tenant improvements are submitted to the Los Angeles Department of Building and Safety (LADBS). Reviewers compare your proposed work against documented existing conditions, so an accurate as-built set is what keeps a project from stalling in plan check.

Our Los Angeles drawings are prepared with California requirements in mind, including Title 24 energy documentation, current ADU regulations, and seismic considerations common to Los Angeles County. That groundwork means fewer correction cycles and a faster path to approval.

Most Los Angeles building departments will not begin a meaningful review without existing-condition drawings, because they establish the baseline for setbacks, egress, occupancy, and how much of a structure is being altered. California ADU law has made garage and accessory-unit conversions especially popular, and each of those projects hinges on documenting exactly what is there before new work is proposed. Starting with a verified as-built set is the single most reliable way to avoid a stalled permit in Los Angeles.

Local architecture

The buildings we measure in Los Angeles

Los Angeles gives you almost every building type in one city. A job in Silver Lake or Eagle Rock may involve a sloped lot with stepped floor levels and retaining conditions, while a property in Highland Park or Mid-City may be a century-old bungalow with layers of alterations. In Venice, Westwood, Sherman Oaks, and Downtown, we also see dense multifamily buildings, mixed-use spaces, and newer infill where field verification matters just as much as in older homes.

That variety is exactly why as-built documentation in Los Angeles needs to start with real site measurement, not guesswork. FastAsBuilt uses on-site laser measurement to capture existing walls, openings, ceiling heights, stairs, and site-driven irregularities, then our senior drafters turn that information into permit-ready CAD files in PDF and DWG format. On hillside properties especially, small offsets and level changes can affect the whole drawing set, so accurate existing conditions are the foundation for the next design step.

Common projects

Why Los Angeles owners need as-built plans

Owners across Los Angeles order as-built plans for very different reasons depending on the neighborhood and property type. In hillside areas, we often support additions where the existing structure does not follow a simple rectangular footprint. In neighborhoods with older housing stock, many clients need measured drawings before planning an ADU conversion or remodel because the house on site no longer matches old records.

Common Los Angeles use cases include:

  • hillside additions for homes with split levels or irregular footprints
  • ADU conversions built around garages or existing lower-level space
  • duplex and multifamily remodels in dense residential areas
  • commercial tenant improvements in places like Downtown and neighborhood corridors

Because no two LA properties are quite alike, verified floor plans help your architect, designer, contractor, or engineer begin with dimensions they can trust. FastAsBuilt provides 2D as-built plans starting at $900 and 3D as-built plans starting at $1,500, with typical residential turnaround in 48 to 72 hours.

Permitting

Working with the Los Angeles Department of Building and Safety (LADBS)

When you submit in the City of Los Angeles, the Los Angeles Department of Building and Safety (LADBS) expects existing-condition drawings to match what is actually built. That matters whether you are preparing an ADU conversion in Sherman Oaks, a multifamily remodel in Mid-City, a tenant improvement in Downtown, or a hillside addition in Silver Lake. In a city with such mixed building stock, assumptions copied from standard plans often break down quickly.

Verified as-built drawings help reduce avoidable revisions by giving your design team a reliable base file before permit documents are prepared. FastAsBuilt measures on site with laser equipment and delivers permit-ready CAD files so your LADBS submission starts from documented existing conditions rather than estimates.
