NEW RESIDENT GUIDE · 新居民安家指南
A practical Round Rock new-resident checklist covering city limits, MUDs, utilities, schools, library access, alerts and local services.
First confirm whether the property is inside city limits or a Municipal Utility District (MUD). Then identify the water provider, choose an electric retail provider, confirm the assigned RRISD school, register for regional alerts and apply for a library card.
第一步先确认房产位于市政边界内还是 MUD 区域；接着开通市政或所属区的水务与垃圾服务、选择电力零售商、按地址核实 RRISD 对口学校、注册地区紧急提醒，并办理公共图书馆借书证。
A Round Rock mailing address does not always mean a home is inside Round Rock city limits. Your exact address determines the city, county, MUD, utility and school services that apply, so verify the address before opening accounts.
Postal addresses do not establish city residency. Properties outside city limits may receive water, wastewater, fire or county services through different entities.
The City provides water, wastewater, garbage and recycling for qualifying addresses; Utility Billing handles applications, rates and account questions.
Round Rock ISD serves Round Rock and portions of surrounding cities and counties; school assignment depends on the home address.
Library cards provide access to books, digital resources, workspaces and free programs; eligibility and fees depend on residency.
Warn Central Texas distributes regional emergency notifications to registered residents by phone, text or email.
Service boundaries vary by address. This checklist summarizes official City and RRISD guidance but does not replace an address-specific service lookup.
