Program Overview

The current export lists 10 accepted plans from 3 providers; provider names include County of Ventura Building & Safety Division, RRM Design Group, and Westside Community Development Corporation.

Plan records cover 288 to 1,188 sq ft and studio to 3 bedrooms where those fields were listed by the source.

Permit and fee context is kept separate from plan acceptance. The data export includes 7 permit requirement records and 4 fee records for Ventura. Permit requirement records include Building permit, Coastal-zone review, and others. Fee records include Standardized plan cost, City-developed plan cost, and others. When a source did not publish a value, the page keeps that field as Not listed in source instead of filling a blank.

Use these listings as a starting point for matching a plan to a property. Source links, checked dates, acceptance notes, and provider records are shown so you can verify whether a plan remains accepted locally, what site-specific review remains, and whether local fees, plan licensing, or provider terms apply. A listing in this directory does not guarantee permit approval for a specific parcel.
