Self-Storage Property Condition Assessments: Roll-Up Doors, Metal Roofs, Paving, Gates and Climate Control

A self-storage facility is the simplest commercial property to describe and one of the easiest to under-report. Most of it is single-story metal buildings on slabs, hundreds of identical roll-up doors, a lot of paving, a fence and a gate. Nearly all of the value is in a handful of repetitive components, which means one defect pattern multiplied by the door or building count becomes the reserve. The E2018-24 baseline is unchanged: a walk-through survey of the ten systems in section 9.4, document review and interviews, and opinions of cost. This page covers where the emphasis goes.

What is different about self-storage

Who orders it. Acquisition buyers and bank and CMBS lenders at origination or refinance. Portfolio deals mean many small reports with the same structure, so consistency between them matters as much as any one finding.

The buildings are simple; the site is not. Drive-up buildings have almost no mechanical systems, so the site, the envelope and the doors carry the report. Water is the main risk: grading that sends water toward buildings, downspouts discharging at door thresholds and slabs set too low let water into units, which damages tenants' goods and becomes a liability, not just a repair.

Unmanned or lightly staffed operations. Many facilities run with remote monitoring, a kiosk and a part-time manager. The point of contact may know little about the roof or the paving history; the maintenance vendor or the owner's records may know more. Say who you interviewed and what was not provided. See the document request list.

Two building types on one site. Drive-up buildings and, on many sites, a climate-controlled building: often multi-story, with interior corridors, HVAC, an elevator, a sprinkler system and a fire alarm. The climate-controlled building is effectively a small commercial building and should be written up system by system like one.

The systems that drive cost

• Roll-up doors. Count them by size, and look for the patterns: uneven gaps at the slab, binding, corroded bottom tracks, dented curtains, improvised weather seals, and a mix of new and old doors that suggests repeated replacement. When many doors in a building show the same symptom, the cause is usually slab movement or drainage, not hardware. Report the cause and the door work separately.
• Roofs. Metal roofs on drive-up buildings (standing seam or through-fastened), low-slope membranes on climate-controlled buildings. The details repeat, so a bad flashing or fastener detail appears on every building. Look at ridge and eave details, fasteners, gutters and downspouts, and rust. See the roofing section.
• Slabs and drainage. Cracking patterns, joint separation, settlement at building ends, and repairs that treat symptoms. Pair every slab finding with the drainage around it. See the structural section.
• Paving. Drive aisles between buildings are usually most of the site: asphalt, concrete, or both. Record the area, cracking, patching, ponding and the seal-coat history.
• Gates, fencing and access control. Rolling or swing gates with operators, keypads, the access-control software and hardware, cameras and site lighting. Operate the gate if the POC allows.
• Climate control. Rooftop or split HVAC units, humidity control, envelope tightness and condensation. A climate-controlled building that cannot hold humidity will show corrosion and odour in units; ventilation shortfalls are often blamed on tenants. See the HVAC section.
• Electrical. Service sized for lights and a few doors often has little room for added cameras, access control or climate units; note the service size and any capacity questions.

Useful lives the reserve table uses

HUD values are the Family column of the CNA e-Tool table. The table is written for housing; where a storage component is not listed, the table's instruction is to assign it to the most closely related category, and the reserve line should say which.

Component	HUD EUL (yrs)	HUD table row	Note
Roll-up unit door	30	3.3.2.8.9	not listed; mapped to overhead door
Automatic opener, overhead door	20	3.3.2.8.10	gate operators, by mapping
Sloped metal roof	50	3.3.4.1.2
Low-slope thermoplastic membrane (TPO, vinyl)	15	3.3.4.2.4	climate-controlled buildings
Gutters and downspouts, aluminum	20	3.3.4.3.1
Asphalt pavement	25	3.2.4.1
Asphalt seal coat	5	3.2.4.2
Concrete pavement	50	3.2.4.3
Security gate, rolling gate	15	3.2.3.2
Fencing, chain-link	40	3.2.6.1
Tenant buzzer, intercom, secured entry system	20	3.6.2.9	keypads, by mapping
Package HVAC rooftop	15	3.4.3.1.11
Pole mounted lights	25	3.2.8.2.7
Paints and stains, exterior	8	3.3.2.4.5

The door, operator and keypad mappings are judgments; the reviewer can substitute the firm's own basis or the owner's replacement history. Security cameras and access-control software have no close HUD category; carry them on a stated basis or mark them engineer to provide. See the HUD table.

Table 1 or Table 2

Table 1 typically carries: active roof leaks into units; water entering units at thresholds because of grading or downspouts; roll-up doors that no longer close or lock; a gate that does not operate or has no working safety devices; trip hazards and potholes in drive aisles; failed site lighting at doors and gates; and, in the climate-controlled building, impaired sprinklers, fire alarm or an expired elevator certificate. Each states its E2018-24 test. See cost categories.

Table 2 carries seal-coat and overlay cycles for the drive aisles, roof replacement or recoating by building, roll-up doors phased across the term (a fixed share per year reads better than hundreds in one year), gate operators and access-control hardware, HVAC in the climate-controlled building, and exterior paint.

Access and sampling

Rented units are locked and belong to tenants, so the interior survey is a sample of vacant units across buildings, sizes and door types, plus corridors in the climate-controlled building. Say how many units were opened, which buildings they were in, and that rented units were not entered. The roofs of single-story buildings can often be seen from a ladder or lift; state how each roof was observed. See representative observations.

Common pitfalls

• Reporting fifty damaged doors without saying why they are damaged.
• Treating the site as parking: drive aisles are the largest paving quantity.
• Writing the climate-controlled building in one paragraph.
• Counting doors from the rent roll instead of on site.
• Missing the gate and access control, which tenants use every visit.

Writing the report

Baseline PCR drafts each section from the field notes, photographs and documents in the E2018-24 order: description with sources, observations, what the point of contact reported, what was not observed and why, then recommendations tied to Table 1 or Table 2 lines, with the unit sample stated. It computes door and paving quantities times the firm's own unit costs and leaves ratings, RUL opinions, mappings and categories for the reviewer, who edits and signs. The sample report shows the format; a storage job follows the same structure with the emphasis above.
