📝 Permits for ADU Construction in Daly City – What to Expect

Daly City follows California’s state ADU laws but also has local planning considerations that must be met. At Royalty Builders, we manage the entire permit process—saving you time and ensuring everything is done right the first time.

Here’s what the process includes:

🔹 Zoning & Setback Review
We verify that your property qualifies for an ADU based on size, setbacks, and lot coverage. Daly City allows both ADUs and Junior ADUs on most single-family lots.

🔹 Design Compliance
The ADU must be compatible with the main home’s appearance. We design with aesthetics and code in mind, avoiding unnecessary delays during review.

🔹 Permit Submission
We submit your application, including architectural plans, site plans, energy compliance documents (Title 24), and any required structural or drainage reports.

🔹 Plan Review & Corrections
City planners may request clarifications or minor changes. We handle all revisions to keep your project moving.

🔹 Building Permit Issuance & Construction
Once approved, we begin construction and coordinate all city inspections until final sign-off.

✅ Daly City complies with California’s ADU laws, including:

• 60-day permit review requirement

• No minimum lot size for ADUs

• ADUs up to 1,200 sq. ft. permitted

• Parking waivers available under specific conditions (e.g. near transit)

Our experience with Daly City’s Planning & Building Department allows us to expedite approvals and avoid common pitfalls.
