Stop managing handoffs across firms. We deliver one coordinated, stamped package by licensed engineers for structural, MEP, and energy in 7 to 10 business days for most projects.
AI agents read your plans and identify clashes, load issues, and common code misses early.

Our in-house, licensed engineers review every sheet, make the judgment calls, and sign and stamp the set.

Most projects move from intake to a coordinated, permit-ready engineering package in 7–10 business days.

We align to your standards, not just defaults. Details and preferences stay consistent across your plan sets.

The result
A faster path to submission, fewer avoidable review comments, and less time chasing corrections across multiple firms.
Industry Partners. Press coverage to prove it.
How it works




We validate
Our AI coordinates the model and runs code and clash checks, then we confirm the set is ready to move forward.


We design
Our licensed engineers design your set according to local codes and regulations in 7 to 10 days.


Receive permit-ready plans!
Our PE-licensed engineer stamps the plans and we send you permit-ready plans.
Frequently Asked Questions
Do you really have licensed engineers in-house, and what is their role in the process?
Yes. Spacial has licensed engineers in-house, including licensed structural engineers and a licensed architect. Our AI helps accelerate early production and coordination, but licensed engineers remain fully responsible for the final outcome. Every structural plan, structural calculation, MEP layout, and energy set is reviewed, validated, and stamped by a licensed professional before it is delivered for permit submittal.
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 across the United 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.
