Architectural drafting services, CAD drawing, and 3D support etc. for California projects
California operates on a triennial statewide code cycle under Title 24 of the California Code of Regulations - twelve integrated parts covering everything from the California Building Code and Residential Code to CALGreen and the Energy Code. The current 2025 edition (based on the 2024 I-Codes with California's own amendments) took effect January 1, 2026, and it pushed further on all electric requirements, wildland-urban interface (WUI) fire hardening, EV charging infrastructure, and - new this cycle - a lower 50,000-square-foot threshold for mandatory embodied-carbon reporting on large nonresidential projects.
Drafting Buddies has drawn on nearly a decade of multi-state drafting experience to become a drafting company California design teams trust with exactly this kind of regulatory complexity. Founded in 2014 and holding an A+ BBB rating, we build every California set against the current Title 24 parts that actually apply to the project - CALGreen, WUI, Title 24 Part 6 energy - not a generic national baseline.
Our California drafting services span permit drawing sets, architectural and structural CAD drafting, MEP and HVAC design drafting, plumbing and civil/site drafting, shop drawings, as-built drawings, Title 24-compliant energy documentation support, 3D modeling and BIM, scan-to-BIM, and rendering for residential, commercial, and multifamily work.
From the Bay Area to Los Angeles, San Diego to Sacramento, our team has drafted for California's most demanding permitting climate for over a decade - and we build every set to survive California's triennial code refresh, not just clear today's review.

Design-for-manufacturing feedback, sheet metal and weldment modeling, and STEP or DXF exports for CNC and laser vendors help turn concepts into prototypes without long delays. Share your scan files for a free quote on scan to BIM and point cloud modeling services anywhere in California.
California buildings carry decades of modifications, and earthquakes and retrofits have often left drawings behind reality. Our scan to BIM workflow starts with your point cloud, whether captured by a survey team, a drone, or a handheld scanner, and ends with a Revit model of structure, walls, openings, roofs, and visible services. Typical California uses include seismic retrofit design, adaptive reuse of downtown offices, hospital and campus upgrades, and industrial plant expansion.
We register and clean the scan data, agree on a level of detail up front, and flag deviations such as out-of-plumb walls or sloping slabs. The resulting model lets design teams in Los Angeles, Oakland, and San Diego start from verified geometry. Contact Drafting Buddies today for a free quote on BIM modeling services in California and start your next project with confidence.
California owners increasingly expect BIM from design through operations, especially on hospitals, life science buildings, schools, and housing. Drafting Buddies builds multidiscipline Revit models at LOD 200 to 400, then adds clash detection, quantity takeoffs, and coordinated sheet sets for submittal. We pay attention to the details California reviewers look for, such as accessibility clearances, energy documentation hooks, and seismic coordination between structure and building services.
Teams in Los Angeles, the Bay Area, San Diego, and Sacramento send us 2D CAD, PDFs, or sketches and receive organized 3D models in return, or we model new designs in parallel with your architects and engineers so the project stays coordinated from the first concept review. Request a free quote for MEP BIM modeling and coordination services anywhere in California and keep your installation schedule protected.
California MEP coordination begins with seismic bracing, because every duct, pipe, and conduit run needs supports that fit with other trades. Drafting Buddies produces MEP BIM models that include hangers, sway bracing, and anchorage zones along with ductwork, piping, sprinklers, conduit, and cable tray. We run clash detection in Navisworks and issue coordination sets organized by level and zone, so contractors in Los Angeles, San Diego, and the Bay Area can fabricate with confidence.
Hospital, laboratory, and cleanroom projects benefit most, where dense services and strict clearances leave little room for field changes. The result is a model your foremen can build from, with fewer RFIs and less rework. Our coordination sets are organized by level, zone, and trade to match how California crews actually build. Contact us today for a free quote on architectural BIM and Revit drafting support anywhere in California.
Structural BIM services in California help engineers, fabricators, and builders coordinate seismic force-resisting systems, foundations, and connections within the building model. Drafting Buddies builds structural BIM models in Revit and Tekla, including footings, slabs, columns, beams, braced frames, moment frames, shear walls, rebar, and steel framing, and produces coordinated drawings and schedules.
Accurate structural modeling is especially important in California, where anchorage, drag elements, and lateral systems must be clearly documented for plan check and construction. We support projects in Los Angeles, the Bay Area, San Diego, Sacramento, and the Central Valley, from parking structures and housing to hospitals and industrial buildings, helping you identify clashes and constructability issues early. Request a free quote for structural BIM modeling and Revit structural drafting services anywhere in California today.
Seismic design is the organizing principle of structural modeling in California. Our team builds Revit and Tekla structural models that keep lateral systems visible: shear walls, collectors, drag struts, braced and moment frames, holdowns, and foundation anchorage, alongside slabs, beams, columns, and reinforcement. These models give engineers a consistent basis for sheets and schedules and help contractors see where congested rebar, embedded plates, and MEP penetrations will collide.
We work on parking structures, podium housing, schools, hospitals, and industrial buildings from San Diego to Sacramento, and we coordinate with architectural and MEP models so openings and sleeves are resolved before plan check comments or field RFIs appear. Send us your project details for a free quote on Tekla steel detailing and shop drawing services anywhere in California.
California steel work is defined by seismic detailing. Our Tekla team models special moment frames, buckling-restrained and concentrically braced frames, base plates, and welded connections with the weld symbols, joint-type callouts, and protected-zone notes that fabricators and inspectors expect. Beyond the primary frame, we prepare erection plans, anchor bolt layouts, bolt lists, and shop drawings for beams, columns, stairs, and miscellaneous metals, with CNC output for the shop floor.
Fabricators in Southern California, the Bay Area, and the Central Valley use us to handle surges without adding permanent headcount. Every model is checked for clashes, member continuity, and material takeoff accuracy so what leaves the detailing desk is ready to cut, fit, and ship. Contact us for a free quote on mechanical room BIM modeling, plant room coordination, and equipment layout services in California.
Mechanical rooms in California carry a unique burden: every pump, chiller, boiler, and tank needs seismic restraint, and the room must still leave space for service. Drafting Buddies models central plants and equipment rooms in 3D with anchorage points, vibration isolation, pipe supports, housekeeping pads, and maintenance envelopes visible to the whole team. Contractors use the model to verify rigging paths, prefabricate piping spools, and sequence installation, while engineers confirm that bracing and clearances work together.
For retrofit and electrification work, such as replacing gas boilers with heat pumps in older hospitals or campuses, we can start from field measurements or scans so the new equipment is coordinated against what actually exists. Request a free quote for electrical BIM modeling and coordination services anywhere in California and keep your project schedule on track.

We create custom families for local product lines, set up sheet sets for plan check, and keep worksets organized so your internal staff or consultants can step in at any time. Studios in Los Angeles, San Francisco, and San Diego use us as an extension of their team during peak submittal weeks, while contractors rely on our models for trade coordination and quantity takeoff. Contact Drafting Buddies today for a free quote on Revit modeling and drafting services anywhere in California and the entire country.
California's as-built drawing requests tend to come from three directions: seismic retrofit programs that need accurate existing framing, tenant improvements in aging offices and medical buildings, and owners who inherited a property with no plans at all. Drafting Buddies measures, photographs, or scans the space, then produces dimensioned floor plans, reflected ceiling plans, elevations, sections, and MEP as-builts in AutoCAD or Revit.
We note exposed structure, shear wall locations, accessibility clearances, and field-verified room data so architects and engineers can start from facts. Projects in Los Angeles, San Francisco, San Diego, and Sacramento often need these documents before plan check, and clear as-builts help avoid rejected submittals and redesign. Request a free quote on as-built drawings and existing condition documentation anywhere in California, with fast turnaround and accurate results.
