Radius Services

Radius Services was started in 1986 to support the building permit application process. We generate area maps and provide owner and occupant data that is physically verified by our staff to ensure the highest accuracy. Our clients include property and business owners, architects, builders, contractors, attorneys, and real estate professionals of varied specializations and disciplines for over 30 years and we are proud to work with them. The San Francisco permitting and notification process is nuanced and we strive to meet the requirements and timing constraints unique to every project. Our goal is to provide our customers with the most accurate data and area maps that meet San Francisco city and California state requirements. We strive to fulfill the customer's needs and expectations throughout the process.
