Track 3 (Permitting & Ordinance Assistant)

Help Manvel residents find answers in the city's published information

Partner challenge No coding needed

The problem

Manvel residents ask city staff the same questions again and again. Can I build on my lot? Can I split my land after I buy it? Is this a city rule or a county rule? The answers are already published, but they're spread across the city's website, the Code of Ordinances, permit forms, maps and Brazoria County's rules.

Who it's for

Manvel residents, including older residents, and small builders. Also the city's permitting staff, who answer these questions every day.

What to build

The minimum is a target, not a rule. Judges score every team with the same five criteria.

Build at minimum

A tool that:

  • answers common property and permit questions in plain language, using only the city's and county's published information;
  • shows the source for every answer, with a link;
  • says "I'm not sure" when it can't answer, and sends people to the city's Development Services department (opens in a new tab).

Stretch goals

  • Address lookup: is this address inside city limits, in the ETJ (the area just outside city limits where some city rules apply), or only in the county?
  • Point people to the city's Development Guide for their kind of project.
  • Work by voice, like a phone call.

The data

All of it is public, on the city's and county's own websites. Nothing to download from us.

Start here

  • No code needed: add the city's pages and PDFs as sources in Gemini Notebook, ask it the questions below, and check each answer against its source.
  • Writing code? Start with a few pages, not the whole website. Get answers with sources working first.

Questions residents ask

Written by the event team from the city's published pages. Not checked by city staff. Use them to build and test your tool, then check its answers against the sources above.

  1. I want to put a shed in my backyard. Do I need a permit?
  2. Do I need a permit to put up a fence?
  3. How do I check on a permit I already applied for?
  4. How much does a permit for a new house cost?
  5. Can I do my own electrical work?
  6. I bought 5 acres. Can I split off 1 acre so my daughter can build a house?
  7. What is a plat, and do I need one?
  8. Is my house inside Manvel city limits, or just in Brazoria County?
  9. I live just outside city limits. Who gives me a building permit?
  10. Is my lot in a flood zone, and what does that change?
  11. Can I bring in fill dirt to raise my lot?
  12. Who approves a septic system?
  13. What is my property zoned, and can I run a small business from home?
  14. My HOA (homeowners association) said yes. Do I still need a city permit?
  15. Do I need a permit for solar panels?
  16. How long does it take to get a permit?
  17. Do I need a permit for a carport?
  18. Which building code does the city use?

Some of these can't be answered from the published pages. A good tool says so and sends people to city staff, instead of guessing.

Good to know

Using the data
  • Use only what the city and county publish. Don't make up rules.
  • Show the date of each source. Rules change, and the online code can be behind.
  • Be gentle with the city's website. Download each page or file once. Don't run tools that hit the site again and again.
  • Parcel data can show owners' names. Don't put names or anyone's personal information into your tool, your slides or an AI tool.
What happens after the hackathon
  • Teams build one-day prototypes. The city doesn't host, support or guarantee anything built on the day.
  • Nothing is released under the city's name without the city's review.
  • Any decision about using an idea stays with the city.

How it's judged
