In R-4, a detached house needs a lot of at least 10,000 square feet and 65 feet wide, set back 20 feet from the street, 10 feet from each side and 30 feet from the rear. It can be up to 40 feet and 3 stories tall (Sec. 2.2.1).

Cited answers from county records

Your agent looks up the parcel, the zoning and any permits or cases, then answers with the sources it used.

Zoning rules come with the section of the ordinance they are from.

Same data and credits as the API

A tool call costs what the same API request costs, from the same credit balance.

Frequently asked questions

What is an MCP server?
MCP, the Model Context Protocol, is the standard way AI agents connect to outside data and tools. An MCP server lets an agent such as Claude or ChatGPT call Placestack while it answers you.
Which AI agents does it work with?
Claude, Claude Code, ChatGPT, Codex and Cursor, and any other client that supports remote MCP servers over HTTP.
What is the server URL?
https://mcp.placestack.com/mcp. It uses OAuth, so you sign in with your Placestack account when you connect.
How much does it cost?
The same as the API: 1 credit per lookup and 1 credit per 20 search results. The free plan includes 500 credits.
Can I use it in an agent I am building?
Yes. Connect with an API key from the console, using the Claude Agent SDK, the OpenAI Agents SDK or any MCP client.
