City hears plan for permit-ready ADU program to speed homebuilding

Lompoc — RRM Design Group told the City Council it has drafted six schematic “permit-ready” ADU plans and a neighborhood context study intended to streamline the city’s accessory dwelling unit approvals and reduce costs for homeowners.

The presentation, delivered by Rachel Hollander of RRM, said the firm and city staff have developed four detached ADU footprints and two garage-conversion plans informed by three local architectural characters — Mediterranean Spanish, cottage agrarian and California ranch — and by recent state law changes regarding ADU programs.

Hollander said the project responds to a state bill that “took effect January” and requires jurisdictions to develop a program for preapproval of ADU plans; she noted the law requires jurisdictions to develop a “program” but does not itself mandate that municipalities produce the preapproved plans. The city committed to preparing plans in its recently updated housing element, Hollander said. “At the end of this project, we’ll not only have the plans available on the city’s website, but there will be a handbook or an informational guide,” she told the council.

Why it matters: Preapproved plan sets are intended to cut plan-preparation costs and shorten plan-review time at building and safety. Hollander said jurisdictions that use permit-ready plans typically reduce applicants’ consultant costs because most of the technical review has already been completed.

The plan details Hollander previewed include two one-bedroom detached plans (350 and 490 square feet), two two-bedroom detached plans (640 and 650 square feet) and two garage-conversion options (a studio for a single-car garage and a one-bedroom layout for a two-car garage). Hollander said the team coordinated with building and safety to limit on-site review to site-specific elements such as foundations, utility connections and minor modifications.

Council discussion focused on why the city is developing its own plans rather than buying preexisting plan sets from other California cities. Hollander said her team frequently evaluates local soil and structural requirements and performs a context study to tailor plans to each city. “The styles that were proposed as part of Encinitas project would not have been our recommendation for the city of Lompoc,” she said, adding that geotechnical reports and foundation design remain site-specific elements.

Council members also asked about uptake and whether 55 ADUs permitted since 2017 indicates local demand. Hollander said ADU construction remains costly — “hundreds of thousands of dollars” for detached units, she said — and that permit-ready plans reduce only part of the total cost by removing much of the bespoke design expense.

What’s next: Hollander said the schematic plans will be finalized by the end of summer, then the construction-ready plan set and handbook will be completed and returned to council in winter for formal adoption of the program. Staff and the consultant said they would consider additional targeted outreach before the formal public hearing and would consult building professionals and designers to test the footprints for constructability.

Actions (meeting record): - No formal council action required at this informational presentation; consultant and staff will return with final plan sets and handbook for a future council decision (direction to return).

Discussion vs. decision: Council discussion was informational only; no ordinance or resolution was adopted at the meeting. Staff and the consultant were directed to finalize schematic plans and bring construction-ready materials and a public-handbook back to council for formal approval this winter.

Clarifying details extracted from transcript: - “55 ADUs have received certificates of occupancy in Lompoc since 2017,” per RRM’s presentation. - Draft plan footprints include two 1-bed/1-bath detached plans (approx. 350 and 490 sq ft) and two 2-bed/1-bath detached plans (approx. 640–650 sq ft); two garage-conversion options include a studio and a 1-bed/1-bath for two-car garages. - Consultant recommendation: property-specific geotechnical reports and foundation design remain required for detached ADUs; preapproved plans reduce but do not eliminate site-specific investigations.
