Zoning check
What the zoning allows on a lot: the zone, its main uses and height or density limits in Los Angeles; in Houston, which has no zoning, the city’s lot-size, building-line and historic rules.
What it answers
Section titled “What it answers”- Can I open a cafe here?
- Is this lot zoned for apartments?
- How tall can I build?
For the agent, the tool is described as: Zoning at a place. Los Angeles: zone string from ZIMAS, its class and main uses (summary of LAMC chapter 1), height district floor area ratio and height (LAMC 12.21.1), General Plan land use, and whether a stated use is on the zone’s use list. Houston: explains there is no zoning and reports special minimum lot size, building lines, historic districts and the parcel’s present use; deed restrictions are not mapped. Give use in the person’s words when they name one.
Who it is for
Section titled “Who it is for”Inputs
Section titled “Inputs”| Input | Type | Required | Default | Notes |
|---|---|---|---|---|
place |
Place | yes | Where a tool runs when it does not need a scan: a scan id, a CoStar property id (all its scans), an address,. Filled from the selected building. | |
use |
string | What the person wants to do there, in their words (a cafe, a daycare, apartments). |
An input that nothing fills (the selected building, a saved preference, a persona’s preset) becomes a question to the person. The agent asks only for those.
Data used
Section titled “Data used”| Layer | Id | Needed | If it is missing |

How it works
Section titled “How it works”Zoning check: the zone on a lot and what it allows, as the city’s own map and code say.
Reliability
Section titled “Reliability”Every metric and finding carries its layer, its method and a high, medium or low label, set by the tool for each value. See findings and reliability.
Limits
Section titled “Limits”- Needs: public.zoning. On a scan without it, the verdict is
unknownand says why. - A result is a planning aid, not an inspection.
On the made-up test home
Section titled “On the made-up test home”This section was written by running the tool when the docs were built, on a hand-made RoomPlan export (no real place was scanned), with no sponsor keys and the network switched off.
Cannot answer here This place has no location, so there is no zone to read.
A phone scan has walls, doors, windows, rooms and objects, but no location, no photos and no property record.
