How 10hub works — and the fine print, in plain language

Two tools, one workspace: price a residential job, then draw the permit-application set for it, all in this browser. This page says exactly what you get, what you don't, and where your information lives. It is short on purpose — read all of it.

What you get

The estimator produces a line-item construction budget: trade scopes, finish tiers, regional pricing, and — for cities in our library — the city's own published permit fees, itemised in the city's own words. Estimates are preliminary and say so on their face.

The permit plans service turns field dimensions into a multi-sheet permit-application PDF: floor plans, dimensions, code notes, plumbing isometrics, and a cover sheet that runs automated dimensional code checks and prints the result. With a library city chosen, the cover carries that city's adopted code editions and reconciles the set against the city's own submittal checklist — every sheet it deliberately omits is stated, with the reason.

This is real: a bathroom set drawn by this tool was submitted to the City of Elk Grove and the permit issued with zero corrections, first pass.

What a set is — and is not

A generated set is a permit-application package. It is not a stamped architectural or engineered design, and not an energy compliance certificate. Structural design, the Title 24 CF1R, and any soils report are deferred submittals by others — the cover sheet says which.
Plan geometry is drawn to the dimensions you enter. It is not a survey of your building. Field-verify every dimension and existing condition before ordering material, fabricating, or building.
Code citations are to the 2025 California Building Standards Code and its January 1, 2026 errata. Local amendments may be more restrictive and govern; for cities in the library the set prints the ones we have read out of the city's own documents.
No warranty of plan-check approval is made or implied. You are the applicant, and the building department has the last word.

The beta promise

You are using 10hub during its beta, and the deal runs both ways. If a set drawn here comes back from a plan-check counter with corrections, send us the corrections letter — every item on it becomes a fix: to a drawing module, to a city profile, or to the "what you still must provide" list. That letter is the most valuable thing a beta user can hand us, and it is treated that way.

The same goes for anything smaller — a confusing screen, a number that looks wrong for your market, a city we should add. The Feedback link in the top strip of every page composes a report you can send us; nothing goes anywhere until you send it.

Privacy — where your information lives

Nothing here identifies you. Your company name, your jobs and everything you type stay in this browser; a price range leaves it only when you press Send, and the request form says where it goes. The homeowner site keeps one cookie, so your free estimate for the week and, once you sign in, your quotes follow you; nothing else is tracked.

We count pages. To see which tools get used, we add one to a counter each time a page is opened and note the site a visitor came from, never the page or the search they typed. No list of visits exists. To tell two visitors apart within one day, a random code for that day is combined with your connection details into a short hash that is destroyed the next day, after which nothing can be traced back. Browsers that send Do Not Track or Global Privacy Control are not counted at all. These numbers are never sold or shared. The free estimate is one a week per household: we keep a cookie, a hashed copy of your connection address and, once you sign up, your email to tell one household from another. Card payments are taken by Stripe; we never see the card.

Two things do leave this browser, and only these:

Pricing. When a tool prices a job it sends the job's measurements and selections — sizes, product, system, rooms — to 10hub's own server, which holds the rate book and answers with the itemised range. No name or contact details travel with that request, and the server keeps no copy of it.
Site-walk requests. When you press Send, the details you entered on that form (name, phone, email, address, notes) plus the priced job go to 10hub's office, via our form provider (Formspree), after you tick the consent box. 10hub calls to confirm. As site walks open up, your request goes only to a licensed contractor 10hub chooses for that kind of job, so they can walk it; it is never sold on or posted anywhere.

Two honest consequences of keeping your work in the browser:

Clearing this browser's site data deletes your work. The plan maker's job inbox has Back up / Restore buttons — use them.
Your work does not follow you to another device or browser, except through that same backup file.

The plan maker's drawing engine (Pyodide) loads from a public CDN on first visit. That request carries no project data — it is the engine arriving, nothing leaving.

Terms of use

This software is proprietary. The tools on this site — their code, layouts, drawing engine, pricing tables, rate books, catalogs, jurisdiction data and text — are copyrighted works of 10hub and are licensed to you for one purpose: estimating and planning your own project, or a project you are quoting for a customer. Copying, downloading, scraping, mirroring, reverse engineering, or reproducing any part of the site or its data for use in another product or service is prohibited without written permission. Automated access to the site or its price data is prohibited.
Estimates are preliminary budgetary figures, not quotes, offers, or contracts. No obligation exists on either side until a written agreement is signed.
Generated drawings are instruments of service and remain the property of 10hub. You may use sets you generate for permitting and building your own project.
You are responsible for the accuracy of the dimensions and conditions you enter, and for complying with your jurisdiction's requirements — including who may prepare plans for your project type under California law.
During the beta the tools are provided as-is, and features may change. We may get things wrong; the automated checks and the honesty of the output are designed so that when we do, it is visible rather than hidden.
California only, for now: the code citations, fee schedules, and check figures are Californian. Outside California the numbers do not apply.
