Measured drawings built on real Arcadia conditions

If you own property in Arcadia, an accurate set of as-built plans is the starting point for almost any building project. Arcadia is an affluent San Gabriel Valley city of large estate lots near the Santa Anita racetrack, known for extensive custom rebuilds.

Whether you are adding square footage, converting a garage, or preparing a property for sale, permit reviewers and trades all rely on drawings that match the building exactly as it stands today. 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 Arcadia 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 City of Arcadia Building Services Division.

Why Arcadia owners order plans

Projects that start with accurate as-builts

Across Arcadia, 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 Arcadia. 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 Arcadia starts with drawings that match the current building exactly.

Permit submittals

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

Buying & selling

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

Insurance & records

Permitting in Arcadia

Drawings the City of Arcadia Building Services Division 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 Arcadia, plans for additions, accessory dwelling units, and tenant improvements are submitted to the City of Arcadia Building Services Division. 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 Arcadia 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 Arcadia 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 Arcadia.

The buildings we measure in Arcadia

Arcadia’s housing stock reads very differently from older, tighter parts of Los Angeles County. In neighborhoods like Upper Rancho, Santa Anita Oaks, Highland Oaks, and Baldwin Stocker, you see broad suburban lots, larger single-family homes, and a steady mix of custom rebuilds and expansions. Near Downtown Arcadia, the pattern shifts toward more compact lots and newer infill, but the city is still defined by substantial homes with additions layered over time.

That matters when you need accurate as-built drawings. On Arcadia properties, the real conditions often include irregular footprints, deep rear additions, attached or converted garages, and second-story work that changed the structure long after the original house was built. FastAsBuilt measures on site with laser equipment, then our senior drafters turn those field measurements into permit-ready CAD files in PDF and DWG format. For Arcadia homes, especially estate properties and custom remodels, that measured approach helps capture what is actually there instead of relying on old plans that no longer match the house.

Common projects

Why Arcadia owners need as-built plans

Owners in Arcadia usually come to us when a project starts with a big question: what exactly exists today? In a city known for extensive custom rebuilds, that question comes up before home additions, second-story additions, and ADU conversions. It is especially common on larger properties around Upper Rancho and Santa Anita Oaks, where prior remodels, enclosed patios, expanded primary suites, or reworked garages can make old drawings unreliable.

We also see demand tied to site complexity. Arcadia includes hillside conditions in some areas, and those projects benefit from clear existing-condition plans before design begins. Typical use cases include:

  • documenting a house before a major addition or full interior reconfiguration
  • measuring for a second story on a home that has already been expanded once
  • creating accurate plans for an ADU conversion from an attached or detached garage
  • verifying existing layouts on sloped lots before hillside addition work

Because Los Angeles County properties vary so much, template drawings rarely hold up. Measured as-builts give your architect, designer, or contractor a dependable base to work from.

Permitting

Working with the City of Arcadia Building Services Division

When you submit to the City of Arcadia Building Services Division, existing conditions need to be shown clearly and consistently. That is true for the kinds of projects Arcadia owners commonly pursue, including additions, second-story work, and ADU conversions. In a permit environment shaped by Los Angeles County’s high level of scrutiny, missing dimensions or plans that do not match the house on site can slow everything down.

FastAsBuilt helps you start with verified information. We laser measure the property in the field and deliver permit-ready CAD files, including PDF and DWG, so your design team can prepare a cleaner submission package. For most residential projects, our turnaround is typically 48 to 72 hours, with 2D as-built plans starting at $900 and 3D as-built plans starting at $1,500.

Knowing the buildings is half the job; knowing the reviewers' checklist is the other half. Projects in Arcadia route through the City of Arcadia Building Services Division, and our drawing sets are organized the way its plan checkers expect — dimensioned existing-condition plans, consistent layering, and clear notation of anything that affects setbacks, egress, or occupancy. Los Angeles County is one of the most permit-intensive jurisdictions in the country.

“We needed as-builts of our 1920s Craftsman before starting a rear addition. The crew measured everything in one morning and the drawings came back in two days — our architect said they were the cleanest existing-condition set she'd worked from.”

“Converted our detached garage into an ADU. FastAsBuilt documented the garage and the main house, and the plans sailed through Long Beach plan check without a single correction on the existing conditions.”
