What can you actually do with a piece of Denver?
The zone district in plain words, what the lot can hold, whether you can run a short-term rental there, the tax on the lot and flood risk, for any spot in the city. Built from the City and County of Denver's own records, the Denver Zoning Code and the Revised Municipal Code.

What this shows that the city map does not
A short-term rental answer for the lot, not a maybe. Denver licenses a short-term rental only in the host's own primary residence, so a whole home rented by someone who lives elsewhere is not allowed anywhere in the city. Click a spot and we read the Assessor's record for that lot: if it holds a home in a district that permits rentals, a host who lives there can rent it, all of it or part, even while away. If it holds no home, or sits in one of the districts that bar rentals, the answer is no. Custom zoning is read too: every PUD and rezoning with waivers made under the 2010 code was read for its uses (59 documents), and older land follows the Zoning Administrator's 2018 ruling that rentals are allowed wherever that code allows homes.
Room for an ADU. Since December 2024 every house in a single unit, two unit, row house or multi unit district can add one accessory dwelling unit: 44,668 acres. We size it for the lot you click (864 or 1,000 sq ft) and give the height the district allows. The City's own ADU map column predates that change; this map follows the code.
The pre-2010 code, named. 13,442 acres were never rezoned into the 2010 Denver Zoning Code, so the old Chapter 59 still sets their rules. The map marks them so you know which rulebook applies.
The tax on this lot. We take the Assessor's 2026 taxable values for the parcel you click and apply the levies of its own tax district: the City, the Mile High Flood District, Denver Public Schools, and any metropolitan, business improvement or water district on top, which can more than double the bill.
How to use it
- Pick a ready-made view, or type what you want, for example "duplex lots out of the floodplain in Highlands".
- 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 verification, a flood determination or a tax bill.
- Zoning lines are simplified for speed. Near a boundary, check the City's zoning map.
- Denver sets no homes-per-acre cap outside its house districts: height, setbacks and building forms decide how many homes fit, so for apartments we give the height, not a count. PUD terms, waivers and the pre-2010 code's standards live in their own documents.
- The short-term rental answer settles the lot, not the person. A license needs proof that the home is your primary residence, and a condo or HOA declaration can ban rentals on its own; the City's records do not show those.
- Tax estimates use the Assessor's 2026 values with the 2025 mill levies, the latest set. The 2026 levies are set in December 2026. Exemptions are included only as the Assessor records them.
- Flood: FEMA's maps as the City publishes them. Denver also regulates land removed from the map by fill, which this map cannot see.
