A3 How It Works

From your plan set to a cited review. In minutes.

Step 01: Upload your plan set.
01

Upload your plan set.

Architectural, structural, civil, mechanical, electrical, plumbing. Any drawing type, at any design phase.

Step 02: Rhonda identifies your jurisdiction and scope.
02

Rhonda identifies your jurisdiction and scope.

Location, occupancy classification, work type, climate zone. Rhonda figures out which jurisdiction reviews this project and which category it falls under.

Step 03: Rhonda pulls every applicable requirement.
03

Rhonda pulls every applicable requirement.

Federal regs, state codes, local amendments, fire district manuals, municipal ordinances, industry standards. One recent project pulled 63 distinct requirement sources for a single 1,183-square-foot tenant improvement.

Step 04: You get a cited report.
04

You get a cited report.

Every finding is anchored to a page in your plan set, and to a written rule when one applies. You get the same comments the permit office would write, without the back-and-forth.

A4 Why Rhonda

What makes Rhonda different

01

Knows your local rules, written or not.

Local amendments, fire district manuals, and the unwritten habits that have you calling the permit office. Rhonda knows them all.

02

Knows what the permit office flags.

Built on the comments permit reviewers actually send back. Same notes your permit office would write, no more, no less.

03

Minutes, not weeks.

A full plan set, reviewed in minutes. Run it during design. Run it before submission. Run it as often as you want.

04

Same workflow, every jurisdiction.

Most tools cover one code or one city. Rhonda figures out the right rules per project, in every jurisdiction.

A6 FAQ

Questions, answered

01
Will my plans or data be used to train AI models?

No. We don't train AI models on customer data, and we don't share your plans with third parties. Read the full commitment in our privacy policy and terms of service.

02
Can you sign our NDA?

Yes. Send it over and we'll get it signed before you upload anything.

03
What about local amendments? My city has its own thing.

Yes, and that's the point. Standard codes are the easy part. Rhonda also pulls local bulletins, fire district manuals, city amendments, and more. 30+ U.S. jurisdictions covered today, with new ones added regularly.

04
I don't trust AI for safety-critical work.

Fair. Rhonda doesn't sign and stamp plans. Your architect of record does. Think of Rhonda as a pre-check: it flags the same issues a permit reviewer would, with citations, so your team can fix them before submission.

05
What does Rhonda review?

All disciplines: architectural, structural, civil, mechanical, electrical, and plumbing. Any project type: commercial, residential, mixed-use, infrastructure, industrial. Any phase: new construction, additions, tenant improvements, renovations. Don't believe us? We'll prove it.

06
What file formats do you accept?

PDF today. Send the same file you'd submit to your local building department.

07
How long does a review take?

54 minutes on average. Run it during design or right before submission, as often as you want.

08
How does Rhonda fit with our internal review?

Rhonda runs first. Most customers generate their first report on a CD50 or CD80 set, well before the design is complete. Your senior team then reviews a cleaner plan set, so they can spend their review on design decisions instead of catching basic misses.
