Serving the greater Los Angeles region
Southern California moves fast, and your project shouldn't wait weeks for accurate drawings. FastAsBuilt delivers field-measured as-built plans for homeowners, contractors, architects, and designers throughout Los Angeles County, Orange County, and the Inland Empire. Whether you're planning a remodel in Santa Monica, adding an ADU in Pasadena, converting a garage in Anaheim, or documenting a commercial suite in Downtown LA, our local crews capture existing conditions with laser precision and turn them into permit-ready CAD files — typically within 48–72 hours of the site visit.
Turnaround times are estimates and may vary based on project complexity and scheduling.
Projects that start here
The most common Southern California orders tell the story of the region itself. ADU and garage conversions dominate residential work: statewide ADU law plus local incentive programs have made backyard units the fastest-growing project type from Long Beach to Riverside, and every one of them begins with measured drawings of the existing house and lot. Hillside additions in Los Angeles, second-story additions on tight Orange County lots, historic Craftsman and Spanish Colonial Revival remodels in Pasadena and Riverside, and kitchen-to-studs renovations in post-war tract homes all rely on the same foundation: an as-built set that matches the building exactly as it stands. On the commercial side, we document office suites, restaurants, retail spaces, and the Inland Empire's vast warehouse and logistics buildings for tenant improvements, change-of-use applications, and lease exhibits.
Built for local permitting
Permitting is where Southern California projects live or die. The City of Los Angeles Department of Building and Safety (LADBS) is famously rigorous about matching submitted drawings to real site conditions, and the dozens of independent building divisions across LA County — Burbank, Glendale, Torrance, Santa Monica, and beyond — each add their own submittal checklists. Orange County cities layer HOA review and, along the coast, Coastal Commission oversight on top of standard plan check, while Riverside and San Bernardino County departments are processing record volumes of ADU and industrial applications. We format every drawing set for the jurisdiction it's headed to: dimensioned existing-condition plans, consistent AIA layering, Title 24 energy documentation where required, and clear notation of setbacks, egress, and occupancy so reviewers can move quickly.
A building stock that punishes guesswork
The region's architecture spans a century of construction styles — 1910s Craftsman bungalows, 1920s Spanish Revival, mid-century ranch homes and hillside moderns, dense multifamily buildings, stucco tract suburbs, and contemporary infill. Decades of unpermitted remodels and quiet additions mean the plans on file at the county rarely match what's actually standing. That's why we measure everything on site with laser tools instead of tracing old records: wall thicknesses, ceiling heights, window and door locations, and every fixture, verified in the field before it reaches a drawing.
Fixed pricing, local crews
2D as-built plans start at $900 and 3D plans at $1,500 for properties up to 1,500 square feet, with transparent per-square-foot pricing above that — no hourly billing and no quote-waiting. Every order includes print-ready PDF and editable DWG files, revisions included, delivered by licensed, insured, California-based teams that schedule quickly anywhere from the Westside to San Bernardino.
