About ArchPermit
ArchPermit is an AI-native tool for preparing architect-reviewed ADU permit packages. It is built “grounded, not guessed”: every requirement is cited, uncertainty is surfaced, and nothing is permit-ready until a licensed professional seals it.
- Overview
- ArchPermit is software that prepares draft ADU (accessory dwelling unit) permit packages for U.S. residential projects. It turns a plain project brief into a jurisdiction-specific, source-cited requirements checklist and an assembled draft package — always marked Draft — pending licensed review until an independent licensed architect reviews and seals it. ArchPermit is not a licensed architect, engineer, or law firm, and it does not provide legal or professional engineering advice.
- What ArchPermit does
- ArchPermit resolves the Authority Having Jurisdiction from an address, builds a cited requirements checklist (each item links a government source with a last-reviewed date), reads your uploaded documents to extract permit-relevant facts, assembles a draft permit package, and routes that package to an independent licensed architect for review and seal. When a source is contradictory or confidence is low, it fails closed and flags the uncertainty for a human rather than inventing a requirement.
- Pricing
- Free: prepare one ADU package end to end (jurisdiction resolution, cited checklist, AI intake chat, and a draft watermarked PDF) for $0. Pro: $39/month or $390/year for unlimited projects, AI document intelligence, one-click package generation and export, and priority reviewer sourcing. Licensed review & seal: not an ArchPermit fee. We connect you to an independent licensed architect; they set their own fee and you pay them directly — ArchPermit never sets it, collects it, or takes a cut. Paying ArchPermit never removes the draft-until-sealed safety gate.
- Who it's for
- Homeowners, designers, builders, and real-estate professionals preparing an ADU permit submittal who want grounded, cited requirements and a clear path to a licensed-architect review — instead of guessing at a jurisdiction's checklist or paying for a full custom engagement before they know what's required.
- Coverage facts
- ArchPermit has grounded, source-cited ADU requirements for all 50 U.S. states and the District of Columbia, plus deeper city-specific checklists for a growing set of cities. Every requirement carries a citation to an authoritative source and the date it was last reviewed; items that vary locally are flagged to confirm with the permitting authority.
