# PropertyZoned.com — Full Site Guide for AI Systems

This is a structural and navigational companion to /llms.txt. It exists to
help AI answer engines, retrieval systems, and citation-seeking crawlers
understand the shape of PropertyZoned.com's content in more depth than the
short-form index. **It contains no per-city or per-state regulatory values**
— no fees, no square-footage limits, no setback numbers, no permit costs.
Every specific zoning, permit, or land-use rule lives on the site's own
data pages, each with its own source citation and last-verified date. This
file only describes what kinds of pages exist, how they are organized, and
how PropertyZoned sources and verifies its data.

## What this site is

PropertyZoned.com is a national zoning, permit, and land use information
engine covering the top 100 US cities. It provides structured, source-cited
data on zoning rules, ADU (accessory dwelling unit) regulations, permit
requirements, home business rules, and short-term rental laws — replacing
hours of manual research across scattered government websites.

## Route types and what they contain

### City-level pages (per city, up to 100 cities)
- `/city/[state]/[city]` — City zoning overview: general zoning framework, links to every topic below for that city.
- `/city/[state]/[city]/adu` — Accessory dwelling unit (ADU) rules for that city: size limits, occupancy rules, permit path, sourced per field.
- `/city/[state]/[city]/home-business` — Home occupation / home business rules for that city.
- `/city/[state]/[city]/short-term-rental` — Short-term rental (Airbnb-style) rules for that city: registration, permits, occupancy limits.

### State-level pages (51 jurisdictions: 50 states + DC)
- `/state/[state]` — State zoning law overview.
- `/state/[state]/adu-laws` — State-level ADU legislation, including states with no statewide ADU law (explained as local-control landscape, not a data gap).
- `/state/[state]/preemption` — State preemption law coverage: whether state law overrides local zoning for ADU and/or short-term-rental topics, with an honest verified / ambiguous / unreachable disposition per topic.
- `/state/[state]/short-term-rentals` — State-level short-term rental (STR) hub: aggregates per-city STR registration/permit status and state preemption disposition for qualifying states.

### National reference hubs

- `/glossary/[term]` — Individual glossary term detail page, with definition and links to related terms and relevant city/state pages.

## Coverage counts (sourced from repository data enumeration, not estimated)

- 100 cities with structured zoning/permit data (`src/data/cities/`)
- 51 jurisdictions (50 states + DC) with state-level zoning/preemption data (`src/data/states/`)
- 48 glossary terms (`src/data/glossary/`)
- 32 city-to-city comparison pages (`src/data/comparisons/`)
- 25 long-form guide articles (`src/data/guides/`)

These counts describe how many pages of each type exist — they are not
regulatory claims about any individual city or state. For the actual
zoning/permit rule that applies to a specific property, consult the
relevant `/city/[state]/[city]/...` or `/state/[state]/...` page, which
carries its own source citation and verification date.

## Data sourcing methodology

All zoning and permit data on PropertyZoned is sourced exclusively from
official municipal codes, city ordinances, state legislation, and
government-published documents. PropertyZoned does not accept data from
third-party data vendors, real estate platforms, news articles, or other
aggregation services. Primary sources include official municipal code
repositories (Municode, American Legal Publishing, Sterling Codifiers,
city-hosted platforms), city and county building department fee schedules,
planning department published guidelines, state legislation affecting
local zoning preemption, and city council adopted ordinances.

Every data point on PropertyZoned includes a source URL and specific code
section reference so visitors can independently verify the information,
plus a last-verified date shown on every data page. When official code
language is ambiguous or a source is unreachable, the page discloses that
honestly rather than asserting an unverified value — this applies to the
JSON-LD structured data on every page as well, not only the visible text.

## Disclaimer

PropertyZoned.com provides zoning and land use information for general
informational purposes only. While we strive to keep our data current and
accurate, zoning codes and regulations change frequently. The information
on this site should not be used as a substitute for consulting your local
planning and building departments or a qualified land use attorney. Always
verify current regulations with your local jurisdiction before making
