California gives cities 60 days to review an ADU permit. But many don't start the clock until they've formally accepted your application, which can take another month on its own.

Cross the wrong threshold on a small remodel or ADU and the city can make you rebuild the sidewalk in front of your home. It's called public improvements, and it can easily add $50,000 to a project.

In a lot of California cities, building an ADU even one square foot over 750 triggered full impact fees of $5,000 to $50,000. A new state law is changing that.

California's new AB 956 lets homeowners build two detached ADUs alongside their main home. That's three units on almost every residential lot, which effectively ends single-family zoning.

A new California law makes cities give you a cost estimate for required sidewalk and infrastructure work within 30 days of applying for a permit. The catch is that the city's numbers rarely match what a contractor will actually charge.

In California, a three-unit home falls under the same building code as a hospital or an airport. That's a big reason small apartment buildings don't get built.

In San Diego, the city can require you to give up the front two feet of your property before it approves your permit. It's called a dedication, and most homeowners don't find out until they've already paid for design + engineering.
