Important service disclosures

Online property results, AI responses, cost ranges, timelines, model concepts, rental projections, and financing scenarios are preliminary planning information. They are not a permit decision, survey, appraisal, engineering opinion, legal or tax advice, loan offer, construction bid, or guarantee of eligibility, price, schedule, rent, property value, or approval.

Regulated design, engineering, surveying, lending, brokerage, and construction services are provided only under separate written agreements by the parties and licensed professionals identified in those agreements. A website interaction does not create a construction contract or professional-client relationship.
