What’s posted
Page (sanjoseca.gov/.../preapproved-adus) lists 4 vendors with 7 total named/sized preapproved plans: Acsiom Designs (749 sq ft 2bd/2ba), Ca2Homes (499 sq ft 2bd/1ba and 747 sq ft 2bd/2ba), J. Kretschmer Architect (748 sq ft 2bd/1ba and 476 sq ft 1bd/1ba), and LiveLarge (795 sq ft 2bd/2ba). Page also lists 7 additional vendors with plans pending review.
Gap from a fully compliant program: Full plan documents are not hosted directly on sanjoseca.gov; page provides vendor contact/website links for pricing and full plan access rather than direct downloads.
Read via reader proxy (https://r.jina.ai/) after direct WebFetch 403'd. Confirmed a real, active catalog of 7 named/sized plans from 4 approved vendors, consistent with San Jose's reputation as an early AB 1332 adopter. Adversarially re-verified 2026-08-06 by an independent re-fetch agent: Fetched sanjoseca.gov/business/development-services-permit-center/accessory-dwelling-units-adus/preapproved-adus via proxy. Confirms exactly 4 vendors under a 'PREAPPROVED ADU PLANS' heading -- Acsiom Designs (1), Ca2Homes (2), J. Kretschmer Architect (2), LiveLarge (1) -- totaling 7 named plans with sqft/bed/bath specs, matching the claim exactly. A separate 'Currently Under Review (Not Yet Approved)' section lists 7 more pending vendors not yet counted. No PDFs hosted on the city page itself; each approved vendor has a listed website/contact for the actual plan set.
Any other agency can adopt these plans
Cal. Gov. Code § 65852.27, added by Stats. 2023, ch. 759, amended by Stats. 2024, ch. 7 (SB 477) (§ 65852.27(a)(5)) lets any California local agency admit into its own program plans “A local agency may also admit the following accessory dwelling unit plans into the program: (A) Plans that have been developed and preapproved by the local agency. (B) Plans that have been preapproved by other agencies within the state.” A city or county without a preapproval program of its own can post City of San Jose’s plans as part of its own program instead of designing new ones — see the full statewide catalog for more options.
We build and maintain the program page, the plan library and the required third-party submission path for agencies that want to stand this up: $1,950 setup + $3,600/year (year one all-in $5,550).
