A second Black Rock Coffee Bar is in the works for Round Rock, with permit filings pointing to a compact freestanding shop planned for the intersection of East Palm Valley and A.W. Grimes boulevards. The proposed modular building would sit closer to central Round Rock than the chain’s existing RM-620 outpost and could bring another quick-service option to the increasingly crowded Palm Valley corridor. City and state records indicate the project is still in early review.
According to WhatNow, a Texas Department of Licensing and Regulation filing describes the construction as a "1400 SF A modular building restaurant with dining" and lists an estimated price tag of $475,000. The same filing outlines a projected construction window from November 27, 2026, to February 27, 2027, while also noting that these dates reflect the internal schedule on the TDLR entry rather than a confirmed public opening.
Permit records show the project is under review
The City of Round Rock permit portal lists the Palm Valley corner project and flags roughly 1,484 square feet of gross floor area, with review steps and staff comments logged this winter. That listing places the build among active development applications, which means additional reviews and a pre-construction meeting could still be required before any dirt is turned.
Black Rock's local footprint
Black Rock already operates a Round Rock drive-thru at 17220 RM-620, Suite 100, per Black Rock Coffee Bar. The company has been expanding aggressively, and the chain noted that it operates more than 150 locations in recent investor materials, which helps explain the flurry of compact-build permit filings across Central Texas; see Black Rock Coffee Bar for more.
What else is planned at the corner
Local reporting in November 2025 noted that city staff confirmed Black Rock was engaged in permitting for the Palm Valley site and that the same corner is slated for other tenants, including Frost Bank and Whataburger. As reported by Community Impact, multiple applications at the intersection suggest the block could become a small retail node, but timing will depend on each tenant clearing review.
Permitting and construction windows are subject to change, and city filings will ultimately decide whether this second Round Rock Black Rock moves from paperwork to pour-overs. For now, residents who favor quick, drive-thru coffee options can expect to keep seeing the project in planning documents, with its eventual opening tied to how smoothly the permit process and construction timetable unfold.
