Type a question and an address. You get where the lot is, its rules and flood zone, and the office that decides, each line with its source and date. Covers fences, sheds, carports and workshops, pools and spas, driveways (state roads go to TxDOT), fill and floodplain, signs, garage sales and new houses (the septic part goes to the septic office); for anything else, including additions and remodels, guest houses, demolition, septic systems, trees and home businesses, it names the office to ask.
Check every lot in a plat before you buy it
For builders, title companies and installers. Send the addresses; get back, for each lot, who governs it, what the map says about it, and which office issues the permit. Near a boundary it says so instead of guessing.
Lot check for a whole plat
City, extraterritorial jurisdiction or county; utility and drainage district; FEMA flood zone and floodway; special lot-size, building-line and historic areas; the permitting office; the edit date of every map read.
New permits near your work
Permits issued each week by job type and area, starting with unincorporated Harris County. For roofers, pool builders, solar installers and subcontractors.
Lot cost and flood
The elevation rule that applies, past flood claims in the ZIP code, impact fees and utility-district tax, before you make an offer.

How the answers stay right
Every number in an answer appears in the source it cites. A line that fails that check is not shown.
When the published rules do not settle a question, the answer says so and names the office to ask.
When a city or county changes a source, answers built on the old one are withdrawn.
Corrections are recorded and kept. A withdrawn claim does not come back.
Before a place goes live, a checker who did not build it scores 21 practice questions with real addresses. A place goes live at 18 of 21 with no harmful answers.
Where it works today. Elsewhere the check places the address and names the office that decides, with its page; it states no rule or fee.
