AI 仓库情报摘要
FR-AI / ANALYSIS为什么值得关注
该仓库首次提供了关于德语区专业管理住宅单元的真实、透明且可溯源估算，以可复现的公共数据和明确假设公开挑战了常见的约2000万套说法。
适合谁使用
- 寻求精准市场规模的房地产投资者和资产管理人
- 德国、奥地利和瑞士的住房政策分析师与城市规划者
- 瞄准德语区市场的房地产科技与管理公司
- 验证行业声明的研究人员和数据记者
典型使用场景
- 为物业管理软件与服务确定总可寻址市场的基准
- 基于实际管理单元数量而非夸大数据制定投资策略
- 为住房监管和补贴分配的政策决策提供依据
- 验证或修正第三方市场报告与行业演示
项目优势
- 每个数字均附有公开来源链接（如Zensus、Destatis、GdW、Statistik Austria、BFS等）
- 假设条件明确列出，其不确定性影响已被量化（私人房东外包比例导致±500万套波动）
- 包含无需任何假设的硬底数（约1140万套），来自直接报告的管理数据（GdW的910万、GBV的100万、瑞士机构约130万）
- 通过自动化深度研究进行独立交叉验证，25项声明中22项得到确认，3项被反驳，排除了重复计算风险
使用前须知
- 主要不确定性来源于德国私人房东外包管理比例的假设（15–35%），目前没有单一研究提供确切数字
- 商业物业层（约150万套）是基于假设的出租比例和平均单元面积的模型结果，置信度低，非普查级数据
- 公寓/住宅业主协会（WEG）的建筑管理被有意排除以避免重复计算，但若纳入可能使总数超过2000万套

How many professionally-managed homes are there in DACH?
A bottom-up, fully-sourced estimate of professionally-managed (third-party-administered) dwellings in Germany, Austria and Switzerland, plus a separate lower-confidence commercial layer.
Answer: ~15 million professionally-managed residential dwellings (central case), in a defensible range of ~11M to ~19M, on a hard ~11.4M floor that needs no assumptions at all.
Everything here is built from public statistics: Zensus 2022 / Destatis, GdW/vdw, Statistik Austria and the GBV Verbandsstatistik, and the Swiss BFS. Every figure carries its source URL. Every assumption is stated as an assumption.
I built this because I needed the number for my own work and could not find an honest version of it. The figure most often repeated in this market is ~20M. When I sourced it properly, the number came out lower, so this is the lower number, with the workings. The uncertainty section at the bottom says plainly which single assumption drives most of the error, and it is not a small one.
Corrections and better sources are welcome. Open an issue.

Residential is the census-anchored core. Commercial was added as a separate, lower-confidence modeled layer, see "Commercial Hauptobjekte" below.
Bottom line: ~15 million professionally-managed residential dwellings in DACH (central case), in a defensible range of ~11M (low) to ~19M (high). The ~20M figure commonly cited in this market sits at or above the top of the independently-sourced range, not at the centre.
Commercial adds a separate, lower-confidence ~1.5M (range ~1.0–2.5M), see the Commercial Hauptobjekte section below. It is modeled, not census-grade, and materially larger by value than by unit count. Residential + commercial → ~16.5M DACH Hauptobjekte central (range ~12–21M).
Every unit below counts dwellings (Wohnungen): apartments and (where noted) commercial Lokale. Dwellings are already the primary lettable unit, so they map to residential Hauptobjekte. Parking bays and storage (Nebenobjekte) are not in any dwelling count. Where a source lets us see the split, it confirms this: Austria's GBV reports 1,006,700 Wohnungen separately from 483,030 Garagen. We count the former, drop the
