There is a set of drawings that describes your building as it actually exists — every wall, every beam, every electrical circuit, every plumbing line, every structural connection — documented in precise technical detail and stamped by a licensed engineer. These drawings are the definitive record of what was built, where it is, how it connects, and what it is made of.

Most property owners in Los Angeles don't have them.

Not because the drawings don't exist — in many cases they do, filed away somewhere in the LADBS permit archive from the original construction permit. But because the original construction drawings and the as-built condition of the building are frequently two different things. Buildings get modified. Walls get moved. Electrical systems get extended. Structural elements get added, relocated, or removed — sometimes with permits, sometimes without. The original drawings become a historical document rather than an accurate record of the building as it stands today.

As-built drawings — sometimes called record drawings — are the documentation of the building as it actually exists at a specific point in time. They are not the original design intent. They are the verified, field-confirmed record of what is there. And they are the document that determines whether your next project moves or stalls, whether your refinancing proceeds or gets delayed, whether your property sale closes cleanly or generates due diligence disputes, and whether your permit application sails through plan check or generates correction letters that extend your timeline by months.

Every property owner in Los Angeles should have current, accurate as-built drawings for their property. Most don't. And the cost of not having them tends to arrive exactly when the cost is least affordable.

What As-Built Drawings Actually Contain

An as-built drawing set is a technical document package — produced by a licensed architect, structural engineer, or civil engineer — that records the existing conditions of a building across multiple disciplines. The content varies depending on the building type, the purpose of the drawings, and the scope of the documentation effort, but a complete as-built set for a multifamily residential building typically includes:

Architectural plans — Floor plans showing the current room layout, wall locations, door and window positions, stair configurations, and unit boundaries. For multifamily buildings, this includes the common area configuration, the parking layout, and any accessory structures on the lot. The architectural plans record what the building looks like from a space and use perspective — the information that tells you what is where.

Structural drawings — Foundation plan showing the foundation system type, footing locations and dimensions, anchor bolt patterns, and any structural elements at grade. Framing plans showing the floor and roof framing members — the beam sizes, joist sizes, span directions, and connection hardware. Structural details showing the specific connection conditions at critical locations — post bases, beam-to-column connections, hold-down hardware, shear wall nailing patterns. For buildings that have been structurally retrofitted, the as-built structural drawings document the retrofit elements — the moment frames, the shear walls, the diaphragm connections — that are now inside the building's walls.

Electrical single-line diagram — A schematic representation of the electrical system showing the service entrance capacity, the main panel configuration, the circuit breaker schedule, and the distribution to subpanels and major loads. The single-line diagram is the document that a new electrician, a permit applicant, or a lender's engineer needs to understand the building's electrical infrastructure without opening the panel.

Mechanical and plumbing schematics — For larger multifamily buildings, schematics showing the HVAC system configuration, the plumbing supply and waste distribution, the gas supply routing, and the location of major mechanical equipment. For smaller residential buildings, the mechanical and plumbing documentation may be less formal but should at minimum identify the location of shutoffs, the configuration of the water heater and HVAC equipment, and any shared systems between units.

Site plan — A plan view of the entire lot showing the building footprint, the setbacks from property lines, the location of accessory structures, the driveway and parking configuration, the utility connections and meter locations, and the overall site geometry. The site plan is the document that establishes the building's relationship to the lot — the information that determines setback compliance, lot coverage calculations, and the feasibility of additions or new construction on the site.

Why Most Properties Don't Have Current As-Built Drawings

The answer to why most properties lack current as-built drawings is straightforward: nobody required them, nobody paid for them, and the consequences of not having them are deferred until they aren't.

Original construction drawings — the plans submitted for the building permit when the property was first built — are filed with LADBS and are technically accessible through the permit records. But accessing those records is not always simple, and more importantly, original construction drawings are frequently not accurate records of what was built. Construction changes happen during the building process — field modifications, engineer-directed changes, owner-directed revisions — and those changes are not always formally recorded as amendments to the permitted drawings.

The original construction drawings for a 1965 apartment building in Van Nuys show the building as it was designed. They do not show the wall that was removed in 1978 to combine two units. They do not show the electrical panel that was upgraded in 1992 without a permit. They do not show the soft-story moment frames that were installed in 2019. They do not show the garage that was partially converted to storage in 2004. The building that exists today is a layered document — the original design plus fifty years of modifications, some permitted and documented, some not.

The gap between the original drawings and the current building condition is the as-built documentation gap. It is invisible until a transaction, a permit application, or a structural assessment reveals it — at which point the cost of filling it falls on whoever is trying to move forward with the project that needs it.

When the As-Built Gap Becomes Expensive — The Four Trigger Events

The cost of not having as-built drawings is not paid evenly over time. It is concentrated in specific trigger events where the absence of accurate building documentation creates a problem that stops progress until the documentation is produced.

Trigger Event One: Permit Application for New Work

Every permit application for construction work on an existing building requires the applicant to document the existing conditions that the new work will affect. A permit application for an ADU addition requires a site plan showing the existing building footprint and the lot dimensions. A permit application for a structural retrofit requires drawings showing the existing structural configuration that the retrofit will modify. A permit application for an electrical panel upgrade requires a single-line diagram showing the existing electrical service.

When the applicant doesn't have current as-built drawings, the permit application is either incomplete — which triggers correction letters and delays — or it is submitted with inaccurate information, which creates a different problem: the approved plans don't match the actual existing conditions, and the LADBS inspector who shows up in the field finds discrepancies that require plan revisions and re-inspection.

The resolution in both cases is the same: produce as-built drawings of the existing conditions before the permit application can proceed. The difference between having those drawings and not having them at the start of the project is typically four to eight weeks of additional pre-construction time and several thousand dollars of additional engineering cost — costs that would have been avoided if the drawings had been produced in advance.

Trigger Event Two: Refinancing

Commercial lenders underwriting a refinancing of a multifamily property typically require a property condition assessment — a third-party evaluation of the building's physical condition and compliance status. Many PCAs include a review of available building documentation: the permit history, the available drawings, and the evidence of permitted improvements.

A PCA that identifies significant discrepancies between the permit record and the building's apparent physical condition — additions that don't appear in the permit history, modifications that weren't permitted, systems that were upgraded without documentation — generates findings that the lender must address before the loan can close. Those findings typically require either as-built documentation of the existing conditions or a resolution of the unpermitted work — either of which takes time and costs money.

Lenders who encounter properties without adequate building documentation also face an underwriting uncertainty that they price into the loan terms. A property whose structural and electrical systems cannot be accurately characterized from available documentation is a property with an undocumented risk profile — and lenders price undocumented risk with higher rates, lower LTV, or both.

Trigger Event Three: Property Sale

Buyer due diligence on a multifamily property sale typically includes a request for available building documentation: permits, certificates of occupancy, available drawings, and compliance records. A seller who cannot produce current as-built drawings — who can only offer original construction drawings from 1965 that don't reflect fifty years of modifications — is producing documentation that a sophisticated buyer's team will identify as incomplete.

Incomplete documentation in due diligence creates two consequences. The first is a negotiation dynamic that favors the buyer: documented uncertainty about the building's physical conditions is a basis for price adjustment, extended due diligence periods, or contingency provisions that the seller did not anticipate when the property was listed. The second is a potential disclosure issue: a seller who knows the available drawings don't accurately reflect the building's current condition and fails to disclose that gap has created a post-closing liability that can survive the transaction.

Trigger Event Four: Insurance Claim

Property insurance claims on multifamily buildings — fire, water damage, structural damage — require documentation of the building's condition before the loss to establish the scope and value of the damage. A claim on a building without accurate as-built drawings requires the insurer's adjuster to determine the pre-loss condition from physical evidence — a process that is slower, less accurate, and frequently less favorable to the insured than a claim supported by documented pre-loss condition records.

For structural damage claims — particularly relevant in the context of seismic events — the absence of as-built structural drawings means the adjuster cannot accurately determine the pre-loss structural configuration, which affects the scope of the repair that will be approved and the value of the claim that will be settled.

The As-Built Drawings That SKS Produces on Every Project

Every SKS Construction project produces a specific category of as-built documentation — the record of the work performed, verified against the field conditions, stamped by our in-house licensed structural engineer, and provided to the client as part of the project closeout package.

For soft-story retrofits, the as-built structural drawings document the installed moment frames, shear walls, hold-down hardware, and diaphragm connections — the structural elements that are now inside the building's walls and that will be invisible without this documentation. These drawings are the record of what was installed, where it is, what size it is, and how it connects — the information that the next engineer who works on the building needs to understand its structural configuration.

For electrical panel upgrades, the as-built documentation includes the updated single-line diagram reflecting the new service entrance capacity, the panel configuration, and the circuit schedule. This document is the record of the building's current electrical infrastructure — the information that supports any future permit application involving electrical work and that a lender's engineer needs for the PCA review.

For balcony structural repairs, the as-built drawings document the repaired framing configuration — the replaced ledger boards, the new joist hangers, the updated connection hardware — and the condition of the elements that were not replaced. This documentation is the baseline for the next SB 326 or SB 721 inspection cycle.

For ADU construction, the as-built drawings produce the complete record of the new unit — floor plan, structural framing, electrical system, plumbing configuration, and site plan showing the ADU's location on the lot. These drawings are the documentation that establishes the ADU as a permitted, engineered, city-signed-off dwelling unit — the document package that supports AB 1033 condo subdivision, refinancing, and sale.

The as-built drawings SKS produces are not informal field sketches. They are engineer-stamped technical documents — prepared to the standard that LADBS plan check requires and that lenders, title companies, and subsequent engineers rely on. They are part of the paper trail that distinguishes a SKS project from a project that was physically completed but not completely documented.

The Broader As-Built Need — Documenting the Existing Building Before Any New Work

The as-built drawings that SKS produces as part of every project document the work we perform. They do not automatically document the rest of the building — the existing conditions that were present before our work began and that are relevant to future permit applications, transactions, and assessments.

For property owners who are planning significant future construction — an ADU addition, a vertical expansion, a comprehensive renovation — the broader existing conditions documentation is a prerequisite that is worth addressing proactively rather than reactively. A property owner who commissions a complete as-built drawing set — architectural, structural, electrical, mechanical, and site plan — before initiating any new construction has the foundation document that every subsequent project, permit application, and transaction will build on.

The cost of a comprehensive as-built documentation effort — typically in the range of $5,000 to $15,000 depending on the building size and complexity — is a one-time investment that eliminates a recurring cost: the cost of reconstructing existing conditions from field investigation every time a new project requires documentation of the building that exists.

SKS can produce comprehensive as-built documentation for existing multifamily and residential properties as a standalone engagement — not as part of a construction project, but as the foundational documentation effort that precedes and enables future construction planning. Our in-house licensed structural engineer conducts the field investigation, verifies existing conditions, and produces a stamped drawing set that accurately reflects the building as it stands.

What to Do If You Don't Have As-Built Drawings Right Now

If you own a multifamily or residential property in Los Angeles and you don't have current as-built drawings — or if you have original construction drawings that you know don't reflect the current building condition — the question is not whether to address the gap but when.

The answer to when is: before the trigger event, not during it. The cost of producing as-built drawings proactively — as a planned, scheduled documentation effort — is substantially lower than the cost of producing them reactively — under the time pressure of a permit deadline, a refinancing closing date, or a buyer's due diligence period.

The reactive production of as-built drawings under time pressure produces drawings that are less thorough, less accurate, and more expensive than drawings produced under a planned timeline. The pressure to produce quickly creates shortcuts in the field investigation, compression in the drawing production, and reduced opportunity for the engineer to verify conditions that require access or opening of finished surfaces.

The proactive production of as-built drawings — commissioned when the project is not yet in motion, when the timeline is the owner's rather than the transaction's — produces a more complete and accurate document at a lower cost, and creates a resource that protects the owner in every subsequent engagement where the building's physical record matters.
