Signs Your HOA Needs Remediation
Heaved or cracked concrete pads that leave CBU units unlevel or visibly tilted are the most visible indicator of structural failure. A CBU tilted more than 2° allows compartment doors to swing open under their own weight — a USPS security violation that can trigger a delivery suspension notice at the next carrier inspection. Cracking along the edge of a pad is not a cosmetic issue; it indicates differential settlement that will worsen until the pad fails structurally.
USPS rejection notices or delivery suspension threats are the most urgent signal. When USPS issues a formal notice, the property is on a documented compliance clock. The notice will specify the deficiencies — typically non-compliant hardware, failed parcel locker ratio, unlevel installation, or arrow lock failure — and a remediation deadline. The clock runs from the notice date, not from the date the board approves a contractor.
Arrow lock failures that result in extended mail suspension, corroded or damaged tenant compartments that fail to latch, and ADA complaints from residents about compartment height access are all infrastructure failure indicators, not nuisances to be managed. They are the documented record that a court would examine in an HOA liability dispute over a mail theft enabled by a failed latch, or a resident's claim that inaccessible compartments violated their ADA rights.
The Repair vs. Replace Decision
Repair is appropriate when the CBU hardware is structurally sound, the concrete pad has isolated surface damage rather than structural settlement, and the arrow lock is the only failed component. A pad with a hairline surface crack that does not indicate differential settlement can be assessed and sealed. An arrow lock cylinder worn beyond reliable operation can be flagged for USPS replacement. These are targeted repairs that a maintenance program should be catching before they become failures.
Replacement is appropriate when CBU hardware is corroded beyond refurbishment — visible structural rust, door frames that have lost structural integrity, or tenant compartments with damaged lock housings. Replacement is also appropriate when the concrete pad has heaved or settled such that re-leveling is not structurally viable. A pad that has risen 3 inches on one side from caliche heave cannot be ground flat and re-used as a CBU foundation. It must be removed, the caliche at depth addressed, and a new pad placed. Replacement is the only compliant path when USPS has issued a replacement mandate citing STD-4C non-compliance.
Do not accept a contractor recommendation without a written site assessment. A contractor who recommends full replacement without documenting the specific structural failures — or who recommends repair on a pad that has settled 2 inches — is not operating from evidence. Request a written assessment that identifies each deficiency individually and justifies the recommendation for each.
What a Remediation Project Involves
A full CBU remediation is a permitted construction project. It begins with a site assessment and written scope — the document the board uses to approve the project budget. The scope identifies which stations require demolition and replacement versus repair, specifies the new Florence 1570 Series hardware configuration for each station, and identifies any caliche or drainage conditions that require additional foundation scope.
USPS notification and coordination begins before demolition. The postmaster must be informed of the remediation timeline to arrange alternative delivery during the construction window. Failure to coordinate this results in mail delivery suspension during construction without notice to residents — a significant property management and resident relations failure. Ironpost Works manages USPS notification as part of the project scope, not as an afterthought.
Demolition covers removal of existing CBU units, removal of existing concrete pads, and site preparation. Soil remediation is performed where caliche or drainage conditions require it. Engineered concrete pads are placed, anchor bolts set and cured, and new Florence 1570 Series CBUs installed and torqued to specification. ADA verification is conducted with field measurements documented. Arrow lock coordination is initiated with USPS. Complete documentation — permits, as-built drawings, ADA verification report, USPS sign-off letter — is delivered to the HOA for their records at project close.
Getting HOA Board Approval
Most Arizona HOA boards require a written contractor scope, itemized pricing, and a minimum of two bids before approving a capital infrastructure project. The written scope must identify the specific deficiencies driving the project, the proposed remediation for each, and the compliance outcome (STD-4C compliant, ADA verified, USPS sign-off obtained). Boards that receive a vague proposal — "replace all mailboxes, $X" — are right to ask for more detail before voting.
Ironpost Works provides a written scope and itemized estimate within 48 hours of site assessment. The scope format is designed for board presentation: it identifies each station by location, describes the condition found, describes the proposed scope, and provides itemized pricing by scope element. We can present to boards directly on request — either in person at a regular board meeting or via written presentation materials the property manager can distribute. Properly documented remediation projects are typically approved in a single board meeting.
How to Evaluate Contractors
Verify the Arizona ROC license. Any contractor performing CBU installation work that involves concrete foundations must hold a valid Arizona ROC license — and the license scope must cover concrete and structural work, not just general contracting. License status and scope can be verified at the Arizona ROC website using the contractor's license number. Ask every bidder for their ROC number before accepting a proposal.
Confirm USPS coordination experience. Ask specifically whether the contractor has managed postmaster pre-installation meetings, USPS inspections, and postmaster sign-off on prior CBU projects. Request a reference from a completed HOA remediation project and ask whether USPS sign-off was obtained and whether the timeline matched what was promised. A contractor who has never managed postmaster sign-off cannot do so on your project — they will either delay the completion or leave the property without formal USPS acceptance.
Ask for a written ADA verification report from a prior project. This confirms the contractor understands the ADA measurement requirement and documents it. Ask who pulls the permit on the project and whose license it will be under. On a compliant remediation, the permit is pulled by and under the ROC-licensed contractor — not by the property manager, and not by a subcontractor working under a permit pulled by a general contractor. Ironpost Works carries the license, pulls every permit, and coordinates USPS directly with no subcontractors involved in the licensed scope.
