You're buying a property and need to know whether the work on record was permitted, what unpermitted work means for your ROI, and what disclosure law applies in the state.
You need a fast sanity check on a city you've never worked in. Fees, review timelines, what the local inspectors actually look at first.
You're advising a client on renovation ROI or disclosing work at sale. You need source-cited facts and the right filing path.
