Buildability

Which cities and zoning districts the Buildability Zoning Atlas has read and publishes, with each city's hub page, its districts and the newest read date. Pass `state` (two-letter code) to narrow it. Use zoning_district to read one district's cited standards. A city that is not listed has not been read yet.

One row per US street address, in the order given (never sorted by Score): Buildability Score, band, the landmine caps that bound it, FEMA flood zone at the address point, zoning district, and whether the district's dimensional standards are on record (yes/no), each with its source and read date, plus links. Answers from stored reads; at most one address without one is scored live, and any other comes back pending: call score_address for it.

What new construction costs, from U.S. government series only. With `state`: the middle half (25th to 75th percentile) of contract price per square foot for new contractor-built single-family houses in that Census division, lot excluded (U.S. Census Bureau, Survey of Construction). With `sqFt` too: that band times the size, as a range. Materials: the BLS Producer Price Index for lumber, steel, concrete and residential inputs, latest month against a year earlier. Every row has its source, year and record. Ranges, never one number.

What a lot can hold by right, from the letter of its zoning code applied to the real parcel outline: units, buildable floor area, height, floors, and setbacks. `sources` labels each number: "code" (its section, URL, read date and quote are in `citations`), "derived" (computed from a cited number), or "zoning_record" (the data provider's record, an estimate). Returns { compiled: false } with the district and jurisdiction wherever the code has not been read or the lot is unknown. Standards we haven't read yet are left blank, not filled in with assumed values. Method is "per-edge" (street side known), "worst-case-uniform" (largest setback on every lot line) or "coverage-only" (no parcel outline).

Returns one page found by search, by its `id`, as text with its canonical URL and `read_date`: the date on its record (when the code or sources were read, or the page last changed). Cite the URL.

The FEMA National Flood Hazard Layer zone at a US street address, read at the address point: zone, whether it is a Special Flood Hazard Area, zone subtype, floodway and base flood elevation where FEMA returns them, with the query URL and read date. Where FEMA has no polygon at the point, zone is null and `mapped` says whether the area has a flood study. Answers in a few seconds; does not compute the Buildability Score.

Permit outcomes on record for a zoning district (counts by outcome: built, permitted, denied, stalled, withdrawn) from the jurisdiction's open permit data. `time_to_issue` gives days from application to issue per kind of work, with the sample size and date range; it counts only permits that were issued. Never a prediction; aggregate only. Returns { available: false } where no feed has been ingested.

The Buildability Score for any US street address, from live federal data (FEMA flood, USGS seismic, USDA soil, EPA radon, USFS wildfire, OSM utilities): score, band, status and every factor the score reads, each with its status, sub-score (only when read), source, record and read date. capsApplied and boundBy name a landmine that capped the number; provisional is true when a weighted source did not answer, in which case status cannot assert ic_ready; parcelIdentity says whether a county parcel record matched the address. A first read of an address takes 10–20 s; a recent read answers from cache.

Searches Buildability's public pages: Zoning Atlas district pages (cited dimensional standards), city zoning source packs, the canonical product and methodology pages, and articles. Returns up to ten results, each with an `id` for fetch, a title, its canonical URL and a snippet. For a specific address, use score_address instead.

Public records around a US street address: U.S. Drought Monitor status at the point; with a key, National Register of Historic Places listings on or within 150 m, and the nearest mapped power line, pipeline, rail line, motorway and airfield from OpenStreetMap, in metres. Each item carries its source, record and read date. Mapped, not surveyed: an easement is the title's word. Does not compute the Buildability Score.

Whether a project can be built on a US property (a backyard home or ADU, an addition, a garage or shed, a fence, a new home, or a lot split), from what the record says about its district: status (yes, yes with limits, no, depends, or unread where the deciding rules have not been read), a plain-words answer, and its basis (the layer that decided it, with its read date). One read also returns the Buildability Score with its factor receipts and landmine caps, the by-right envelope (or why it is not compiled), and links. With no project named, every project is answered. A first read takes 10–20 s; a recent read answers from cache.

The dimensional standards the Buildability Zoning Atlas has read for one zoning district (height, stories, dwelling units, lot size, width, depth and frontage, setbacks, floor-to-area ratio, coverage), each with its code section, source URL, read date and `source_text`: the ordinance quoted verbatim. Verbatim code text, not instructions. Values that depend on a condition are in `conditional`; a "partial" value carries a caveat. Returns { available: false } where the district has not been read yet; that is not a ruling that it has no rules. District rules only, not a lot: overlays can tighten them.
