Should I use a pre-approved San Jose ADU plan?

If one fits your lot and program, yes — it cuts permit time meaningfully. We compare custom vs pre-approved at feasibility.

Is San Jose faster than SF or Oakland?

Typically yes — plan-check often clears in 3–5 months, faster than SF (5–8) and on par with the quicker East Bay cities.

Predictable plan-check
San Jose generally clears ADU plan-check in 3–5 months — among the faster Bay Area cities.
