Coast to county line
From beachfront remodels in Encinitas and Coronado to commercial tenant improvements in Downtown San Diego and inland additions in Escondido and El Cajon, FastAsBuilt delivers accurate as-built plans across all of San Diego County. Our local technicians measure existing conditions on site with laser tools, and our senior drafters turn that field data into permit-ready floor plans, elevations, and site plans — all with fixed square-footage pricing and typical 48–72 hour turnaround.
Turnaround times are estimates and may vary based on project complexity and scheduling.
Built for the county's ADU and infill boom
San Diego has leaned into ADU and infill development harder than almost any California county, and the City of San Diego's ADU bonus program has made multi-unit backyard projects genuinely common. Every one of them starts the same way: with accurate existing-condition drawings of the main house, the lot, and any structures being converted. We document garages ahead of conversion, measure lots for detached-unit site plans, and produce the verified drawings designers need before a compliant ADU design can begin — in the city itself and in Chula Vista, Oceanside, La Mesa, and every jurisdiction between.
Drawings local reviewers accept
Most projects in the region route through the City of San Diego Development Services Department, one of the busiest permitting operations in the state, while each incorporated city — Carlsbad, Encinitas, Escondido, El Cajon, and the rest — runs its own building division with its own checklist. Along the shoreline, the Coastal Zone adds another layer of review that makes accurate existing documentation even more valuable. Our drawing sets are formatted for the jurisdiction they're headed to: dimensioned existing plans, consistent layering, Title 24 energy documentation where required, and clear notation of setbacks, egress, and occupancy so plan check moves the first time.
A building stock shaped by the coast
San Diego County's architecture runs from Spanish and Mission Revival homes in older neighborhoods to mid-century ranches, canyon-lot residences on stepped foundations, coastal contemporary builds, and dense urban condos and mixed-use infill. The mild climate encourages indoor-outdoor living — covered patios, enclosed sunrooms, and additions that blur the building envelope — and decades of those modifications rarely make it onto the plans on file. That's why we field-verify everything: wall thicknesses, ceiling heights, window and door locations, and the quiet changes past owners never permitted, all captured before a line is drawn.
Example projects we measure every week
Typical San Diego orders include garage conversions and detached ADUs, kitchen and whole-home remodels, second-story additions on coastal lots, condo documentation for renovations and sales, restaurant and retail tenant improvements, and office suites needing verified floor plates for leasing. 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. Every order includes permit-ready PDF and editable DWG files with revisions included, delivered by licensed, insured, locally scheduled crews.
