What is Tertius?

Tertius is an online services platform that connects residential and commercial property owners and managers with access to private certified and approved inspectors. Tertius was created to conveniently present more options for customers and to potentially shorten the timeline to complete inspections.

Tertius also creates opportunity for certified, local inspectors to be introduced to more customers.

What is the Department of Consumer and Regulatory Affairs’ (DCRA) role?

DCRA protects the health, safety, economic interests and quality of life of residents, businesses and visitors in the District of Columbia by ensuring code compliance and regulating business. To support this mission, DCRA is responsible for regulating construction and business activity in the District. All inspectors included in Tertius are certified by DCRA and licensed in the District of Columbia.

What is the difference between “booking” and “scheduling” an inspection?

“Booking” refers to when a customer selects an inspection agency to conduct an inspection, or a series of inspections, and contracts for their services. “Scheduling” refers to when the inspection agency, in consultation with the customer, sets the date and time that a contracted inspection, or series of inspections, will occur.

Request a W-9 form from Stripe


Stripe does not have a W-9 to provide, as W-9 forms are typically used when payments are made to a vendor in response to an invoice. Because businesses using Stripe don’t actively send payments to Stripe directly, a W-9 form isn’t generally needed.

Additional Information

Stripe makes outbound payments to businesses in the form of payouts, so Stripe will issue a 1099-K form if the appropriate reporting threshold is met. This article is neither legal advice nor tax advice. We recommend that you speak to your lawyer or accounting firm with any questions or concerns around tax reporting. https://support.stripe.com/questions/request-a-w-9-form-from-stripe
