Mailbox and Street Sign Services Across Metro Detroit
There is a version of this work that looks fine from the street and falls apart within a year. The post settles wrong because the concrete was rushed. The mailbox sits half an inch too low, and the carrier starts skipping the delivery. The street sign fades below Michigan’s reflectivity standard, and nobody notices until an inspector does. These are not rare outcomes. They are what happens when mailbox and street sign installation gets treated as a simple job rather than the compliance-driven infrastructure work it actually is.
Mailboxes by Bob has been doing this work across Metro Detroit and Oakland County for years, and our service area reflects where that experience has taken us. We work with homeowners replacing a single post, HOA boards running a full subdivision sign program, property managers coordinating cluster mailbox repairs across a community, and builders who need USPS-coordinated mailbox infrastructure before their first residents move in. Every project in every community gets the same compliance-first approach: confirm the requirements, do the work correctly, and build it to last through Michigan winters.

Who We Serve Across Metro Detroit
Our work reaches a range of clients throughout the region, and the scope of what each one needs varies considerably. Understanding who typically works with us helps clarify whether Mailboxes by Bob is the right fit for a given project.
Homeowners throughout Metro Detroit come to us when a mailbox post has finally given out, when an HOA notice has made a replacement non-negotiable, or when a new installation needs to be done right the first time rather than fixed six months later. A single residential mailbox is not a small job when it has to meet USPS placement requirements and satisfy an HOA with specific material and style rules. We handle the compliance side so the homeowner does not have to.
HOAs and property managers work with us on a larger scale. Cluster mailbox systems for condominium communities, subdivision street sign replacement programs, decorative sign upgrades for established neighborhoods, and repair coordination across multi-unit properties are all part of the work we do regularly. These projects require organized communication, scheduling that works around resident activity, and a finished result that holds up to the demands of shared daily use.
Builders and developers in Oakland County’s active construction market rely on us for mailbox infrastructure during new development phases. That includes working with USPS to confirm approved placement locations, sequencing installation to align with construction timelines, and making sure mail delivery is ready at move-in rather than delayed because the infrastructure was not coordinated correctly.
Our Services Throughout the Region
Every community we serve has access to the full range of Mailboxes by Bob services. The specific compliance requirements vary by municipality and HOA, but the service offering is consistent across our entire coverage area.
Mailbox Services
Our mailbox installation service covers residential curbside installs, HOA-specified replacements, and new construction coordination. Every installation is confirmed against USPS placement requirements before the post goes in the ground. For properties where the existing unit has failed or shifted, our mailbox repair service addresses post rot, concrete base failure, leaning installations, and hardware damage with a clear recommendation on whether repair or full replacement is the right call.
When full replacement is needed, our mailbox replacement service handles removal, disposal, and new installation in one coordinated project. For properties where curb appeal is a priority alongside compliance, our custom decorative mailboxes offer upgraded materials and designs that meet the same USPS and HOA standards as any standard installation.
Multi-unit properties and condominium communities throughout Metro Detroit rely on our cluster mailbox installation service for USPS Cluster Box Unit coordination, site preparation, and installed systems built to handle multi-resident daily use. For builders, our new development mailbox service manages the USPS coordination and on-site scheduling that new construction requires before mail delivery can begin.
Street Sign Services
Our street sign services cover the full range of signage needs for Metro Detroit communities, municipalities, and builders. That includes Michigan standard sign installation to MMUTCD specifications, subdivision street sign replacement for communities with aging or non-compliant signage, and decorative street sign installation for HOAs that want a custom neighborhood identity without sacrificing compliance.
Builders with active sites can rely on our temporary street sign service for fast-turnaround, properly mounted signage that keeps construction sites accessible for contractors, inspectors, and emergency services. For properties dealing with storm damage, vandalism, or general wear, our street sign repair service restores compliance quickly. We also handle custom metal signs and miscellaneous signage for applications that fall outside standard street identification.
Communities We Serve
Oakland County is home to more than 1.2 million residents across dozens of municipalities, according to the U.S. Census Bureau. We work across this region consistently, and each community in our service area comes with its own mix of governing standards, HOA activity, and property types. The pages below provide location-specific detail on the services and compliance considerations relevant to each area.
Farmington Hills is one of Metro Detroit’s most established communities with an active HOA landscape and a mix of residential and commercial development. The Farmington Hills page covers the full range of mailbox and street sign services available in the city, including subdivision sign replacement programs and HOA-compliant residential installations.
Novi is one of Oakland County’s most active development markets, with both new construction projects and well-established residential neighborhoods. The Novi page focuses on mailbox installation, repair, and replacement, with additional coverage of street sign services for subdivisions and active builder sites.
Why Compliance Matters in Every Community
The standards that govern mailbox and street sign installation are not suggestions, and they do not vary by how visible a property is or how active its HOA happens to be. USPS placement requirements apply to every curbside mailbox in the country. Michigan DOT reflectivity and sizing standards apply to every street sign on a public or private road in the state. HOA specifications are contractual obligations for every homeowner in a governed community.
Working with a vendor who understands those requirements before a project starts makes a real difference. A mailbox installed at the wrong height creates a delivery problem. A street sign installed below the required reflectivity threshold creates a safety issue and a compliance liability. A cluster mailbox system installed without USPS coordination creates a move-in delay that no builder or property manager wants to explain. Our process accounts for all of it before a single material is ordered.

The right mailbox or sign installation does not create follow-up problems. It meets the standard, looks like it belongs, and holds up year after year without needing to be revisited. That is the only kind of work we do, and it is the same regardless of which Metro Detroit community you are in or how large the project is.
