What can you actually do with a piece of Los Angeles?
Zoning in plain words, how many homes the lot can take, whether you can home-share it, the tax on the lot, flood and fire risk, for any spot in the City. Built from the City's zoning maps, the County Assessor's roll, the City's rent stabilization list and the Municipal Code.
- acres of single-family zoning where SB 9 allows two homes or a lot split
- 94,461
- rent-stabilized units on the City's list, none of which can be home-shared
- 724,334
- acres of zoning in a Very High Fire Hazard Severity Zone
- 106,727
- acres already under the City's new zoning code
- 5,359

What this shows that the City map does not
A Home-Sharing answer from the lot's records. Los Angeles allows short-term rentals only as Home-Sharing in the host's own primary residence, so renting a home you do not live in is not allowed anywhere in the City. Click a spot and we read the County Assessor's roll and the City's rent stabilization and affordable housing lists for that lot: a home that is not rent-stabilized or income-restricted, in a zone that permits homes, can be home-shared by a host who lives there. Known exclusions produce a no, with the record that decided it. If the required City records do not answer, permission is not established; the map and brief say so and explain how to retry.
How many homes, on this lot. We read the lot's size from the Assessor's parcel map and do the arithmetic for its zone (one home per 800 sq ft in R3, per 400 sq ft in R4 and most commercial zones), then add what state law allows on top: ADUs and JADUs on every home, and on 94,461 acres of single-family zoning, SB 9's two homes or a split into two lots.
Fire, named. 106,727 acres sit in a Very High Fire Hazard Severity Zone on the State's 2025 map or the City's. That changes the answer for ADUs on hillsides and for SB 9, which the City does not accept at all in the fire zone inside the Palisades fire perimeter.
The tax on this lot. Prop 13's 1% plus the voter-approved debt of the lot's own tax rate area (233 of them in the City, from 1.117% to 1.295%), on the Assessor's roll value, with or without the homeowners' exemption.
How to use it
- Pick a ready-made view, or type what you want, for example "SB 9 lots out of the floodplain in Highland Park".
- Click anywhere, or type a street address, to see the rules for that spot.
- Share a view by copying the link. It opens with the same view selected.
Limits, plainly
- This is a screening tool. It is not a survey, a zoning determination, a flood determination or a tax bill.
- Zoning lines are simplified for speed. Near a boundary, check ZIMAS.
- Home counts are the zone's ceilings for the lot size. Q and D conditions, specific plans, setbacks, hillside rules and the Chapter 1A form districts can lower them; density bonus programs (the State's and the City's CHIP) can raise them.
- The Home-Sharing answer is shown only when the available records settle the lot. Registration needs proof that the home is your primary residence, and a landlord or condo association can bar it. Rent stabilization comes from the City's list (snapshot of Jan 15, 2025); where the list is silent, a building of two or more homes built before October 1978 is treated as rent-stabilized. The ZIMAS Housing tab is the official record.
- Tax: FY 2026/27 rates. Direct assessments and special taxes on the bill are not included. A buyer is reassessed at the purchase price.
- Flood: FEMA's current maps. Fire: the State's 2025 map and the City's earlier map, whichever marks a lot.
