Measured drawings built on real Pasadena conditions

Before an architect sketches a single new wall in Pasadena, they need to know exactly where the existing ones are — that is what an as-built set delivers. Pasadena is famous for its Craftsman architecture and protected historic districts, where sensitive remodels demand precise as-built drawings.

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 Pasadena 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 Pasadena Planning & Community Development Department.

Why Pasadena owners order plans

Projects that start with accurate as-builts

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

Historic remodels

Pasadena's older homes demand sensitive, accurate documentation before any renovation in a protected district.

Permit submittals

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

Buying & selling

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

Insurance & records

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

Permitting in Pasadena

Drawings the City of Pasadena Planning & Community Development Department 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 Pasadena, plans for additions, accessory dwelling units, and tenant improvements are submitted to the City of Pasadena Planning & Community Development Department. 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 Pasadena 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 Pasadena 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 Pasadena.

Local architecture

The buildings we measure in Pasadena

Pasadena’s residential character is defined by Craftsman houses, and that matters when you need reliable existing-condition drawings. In neighborhoods like Bungalow Heaven and Madison Heights, homes often have layered additions, deep porches, built-ins, varied rooflines, and room layouts that do not match old paper plans. You also see Spanish Colonial Revival details, older mixed-use buildings near Old Pasadena, and larger properties in San Rafael Hills, each with its own measuring challenges.

FastAsBuilt documents these properties the right way: we send a local crew for on-site laser measurement, then senior drafters turn the field data into permit-ready CAD files in PDF and DWG format. In Pasadena, that level of verification is especially important because template plans and assumed dimensions rarely hold up once you measure an older house with decades of changes.

Common projects

Why Pasadena owners need as-built plans

Owners in Pasadena usually come to us when a project needs a precise starting point, not a guess. That is especially true for historic Craftsman remodels and additions in protected or landmark-sensitive areas, where design decisions depend on what is actually there. If you are working in Bungalow Heaven, Madison Heights, or around Old Pasadena, accurate as-builts help your architect and contractor respond to existing walls, ceiling heights, porch conditions, and previous alterations before new work is drawn.

We also regularly support practical projects such as:

  • ADU conversions based on verified garage or existing floor plan dimensions
  • Additions where older homes have undocumented changes
  • Remodel planning for houses in Hastings Ranch or hillside properties in San Rafael Hills

For residential work, FastAsBuilt typically delivers in 48 to 72 hours. Our 2D As-Built Plans start at $900, and 3D As-Built Plans start at $1,500, giving you a clear base set before design and permitting move forward.

Permitting

Working with the City of Pasadena Planning & Community Development Department

When you submit to the City of Pasadena Planning & Community Development Department, clean existing-condition documentation helps the review process start on solid ground. In a city known for historic neighborhoods and sensitive residential work, reviewers need drawings that reflect the actual building, not a simplified version pulled from an old listing or outdated plan set.

FastAsBuilt provides field-measured as-built drawings that help your design team prepare permit submissions with fewer assumptions. For additions, ADU conversions, and remodels in Pasadena, verified plans make it easier to show how new work relates to the current structure, which is exactly where many permit questions begin.

We know Pasadena buildings

The fastest way to a clean drawing set in Pasadena is a crew that has seen this housing stock before. 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.

We pair that field experience with submittal know-how. Projects in Pasadena route through the City of Pasadena Planning & Community Development Department, 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. 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.
