## Frequently asked questions

### How much does adu cost?

Most adu falls between $1,418 and $4,396, with a typical figure near $2,497 per job. The low end is a straightforward job with no surprises; the high end covers complex scope, premium materials or urgent timing. Where you are in St. Petersburg can change the detail, so compare nearby quotes.

### What affects the price of adu?

No single factor decides it — scope, materials, access and timing all move the total, and the biggest swings usually come from access and scheduling. The specifics vary across St. Petersburg, so confirm them with the provider you hire.

### Is ADUs cheaper in smaller cities?

Often, but not always. Smaller markets can carry a travel or availability premium that offsets a lower local rate, so it is worth checking a nearby city before assuming the lowest published figure applies to you. For St. Petersburg, ask a provider to put that in writing with the quote.

### How many quotes should I get for adu?

Two or three written quotes are enough to see the real market range. Compare the same scope side by side, and ask each provider what is excluded and what would change the price after the quote is accepted. Providers serving St. Petersburg can tell you how it affects a typical job.
