ADU Terminology FAQs
Do I need an in-person submission of plans for an ADU?
Answer: No, the City of San Diego allows electronic submissions of ADU plans through the online permitting portal. However, for some cases involving specific review requirements, such as projects in historic or coastal zones, an in-person meeting may still be recommended or required. CRS Builders can handle the submission process for you, ensuring everything is completed efficiently and correctly.
Do I need a soils report for an ADU?
Answer: Yes, a soils report is often required when building a detached ADU in San Diego, especially if new foundation work is involved. The report evaluates soil stability and ensures the foundation design meets local safety codes. However, if you’re converting an existing structure like a garage, a soils report may not be necessary. CRS Builders will guide you through this step, ensuring compliance and avoiding unnecessary reports when possible.
Do I need coastal development permits for an ADU?
Answer: If your property is within the Coastal Zone, you will need a Coastal Development Permit (CDP) unless your ADU qualifies for an exemption. ADUs that meet specific criteria—such as being at least 4 feet from the property line and not exceeding local height limits—may be exempt. CRS Builders is experienced in navigating San Diego's coastal regulations and can handle the permitting process for you.
Are there specific landscaping requirements for ADUs in San Diego?
Answer: Yes, there may be landscaping requirements depending on your property's zoning and environmental overlays. For example, projects in fire hazard zones often require fire-resistant landscaping, while ADUs in environmentally sensitive areas may need additional planting plans. However, in most cases, San Diego’s ADU regulations focus more on setback and design requirements than specific landscaping mandates. CRS Builders ensures your project meets all local guidelines and aesthetic goals.
What is the plan check process in San Diego, and how long does it take?
Answer: The plan check process involves submitting detailed architectural and structural plans for review by city departments. For ADUs, the initial plan check typically takes 4 to 6 months, depending on the complexity of the project and whether corrections are needed. Expedited reviews may be available for qualifying projects. Our team ensures that your plans meet city codes on the first submission to streamline approvals and minimize delays.
