Where we are now
Today, Spacial delivers full engineering services powered by AI and in-house licensed engineers. Licensed engineers and AI work together from the start. You share the set. Our AI validates design intent, runs jurisdiction-specific code checks, and surfaces conflicts. From day one we coordinate structural, MEP, and energy in one loop. PE-licensed engineers review the model, resolve clashes before submittal, generate the sheets and schedules, and prepare clear responses for plan check. The deliverable is a coordinated permit package stamped by a Professional Engineer (PE) licensed in your state.

Where we
are headed
We are building a self-serve workspace that brings the same coordination into your hands. Upload models or PDFs, see issues flagged in context, request stamps, and track status to approval. Plugins for your design tools let you push updates without breaking the thread. Join the beta to get early access as we roll out invites.
Deliverables include coordinated sheets, calculations, and submittal-ready documentation. We design to the city you are working in and tailor details to that jurisdiction.

Our beta core capabilities
AI code validation
An intelligent review system that analyzes plans at submission. It identifies issues before review, aligns designs with local standards, and tracks every adjustment for full transparency.

Coming to your tools
Works with Revit, AutoCAD, Archicad, and PDFs. Version history protects design intent. Plug-ins sync models to a shared workspace with status and comments. Role-based access. Exports match city formats.
The result is less rework, clearer ownership, and plans that match what the city expects to see.

Frequently Asked Questions
Do you really have licensed engineers?
Yes. We have licensed engineers in-house, including a licensed in-house architect.
Structural Engineer License: S7075 | Architectural License: C-31344
Through our partner network, we support projects with licensing coverage across 43 states, including CA, GA, TX, AZ, and FL.
Do you work with architects, designers and builders?
All of the above.
Architects and designers use Spacial as their all-in-one engineering partner so they can ship coordinated structural, MEP, and energy sets without juggling multiple consultants.
Builders and developers use us when they want a single team responsible for engineering that understands production schedules, options, and repeat plans.
In every case, we plug into your workflow so you still own the client relationship while we handle the engineering.
How do you use AI without compromising safety?
Safety starts with people. AI supports our team by catching conflicts and running code checks at scale, but a licensed engineer reviews the work, signs off, and takes professional responsibility for every project. The technology extends our eyesight, not our liability.
What is "builder-led engineering"?
It means our leadership's deep background in construction informs every engineering decision we make. We anticipate field issues that traditional firms might miss, ensuring our architectural engineering solutions are practical and efficient to build.
How does your process help with getting plans approved faster?
Our focus on constructability and our use of AI to validate plans against local codes before submission helps to reduce plan check delays. By delivering cleaner, more accurate structural engineering and MEP sets, we minimize the back-and-forth with city reviewers.
What areas do you serve?
Today we primarily serve residential projects in over 43 states, including California, Texas, Florida, Arizona, and Georgia.
In these states we provide full structural engineering, MEP, and energy engineering, including energy-code compliance (Title 24 in California and equivalent requirements in other jurisdictions).
If you have a project outside this list, reach out with the city and state; we can quickly confirm whether we can take it on or when coverage will be available.
Can you handle the complete MEP scope for a custom home?
Yes. Our MEP engineers provide a fully coordinated solution. This includes efficient HVAC design, full electrical engineering for modern homes with complex lighting and EV charging needs, and performance-based plumbing design.
What types of residential projects do you specialize in?
We specialize in high-end custom home design, complex remodels, and ADU additions. Our team has extensive experience delivering permit-ready plans for projects throughout California, with a deep portfolio in demanding municipalities like Palo Alto and Los Altos.
What makes Spacial different from a traditional engineering firm?
Spacial replaces multiple engineering consultants with one coordinated partner and delivers a stamped, permit ready set in 7 to 10 business days for most projects. Our AI flags coordination gaps early, and licensed engineers make the final judgment calls and stamp the package. Fewer handoffs means fewer coordination misses and fewer resubmits.
Are you the same company as Spatial?
No. We are Spacial with a “c,” at spacial.io.
Spacial provides residential builders and architects with coordinated structural, MEP, and energy engineering, and we deliver permit ready plan sets stamped by licensed engineers.
Spatial, spelled with a “t,” is a separate company focused on 3D software technology and developer tools, not an engineering firm preparing permit drawings or stamped sets.
