Building management and maintenance has gained its importance after a series of disastrous building-related incidents in Hong Kong. To facilitate the management of an apartment building, homeowners usually form an owners’ association among themselves and/or appoint an external property management agent (PMA) to manage the building on their behalf. Empirical studies found that the involvement of these bodies was conducive to a better-performing built environment, and that premium was added to better-performing properties. Yet, these studies often took the formation of owners’ association and engagement of external PMA in a building as dichotomous variables in exploratory models, and thus ignored the variations in the adopted building management practices in different buildings even with the same building management setting. Making use of the data collected from two previous research projects, a hedonic price analysis was carried out to study whether specific building management practices added value to the properties concerned. The analysis results indicated that properties in buildings with good documentations (eg keeping of as-built architectural drawings and incident records), thoughtful emergency planning (eg presence of emergency plan and regular fire drills) and property-all-risk insurance coverage were sold at a premium, ceteris paribus. Policy and practical implications then follow.
Recent literature such as Yiu (2007) and Yau (2008) has highlighted the long-lasting problem of building neglect in Hong Kong. Painful consequence of such neglect is best illustrated by the localised outbreak of the Severe Acute Respiratory Syndrome in Amoy Gardens in 2003. In spite of this lesson, building-related incidents such as tragic fires and falling building fabrics are common in the city. To sustain a healthy and safe urban environment in Hong Kong, the local government launched two public consultations on the approaches to ensure that the building stock in the territory could be properly serviced and how a building care culture could be fostered (Housing, Planning and Lands Bureau, 2004, 2005). Yet, we need to understand the root of the current predicaments in building management and maintenance before a sensible solution can be devised.
Fong (1984) attributed the building problems to the high-rise high-density development pattern adopted in Hong Kong. In multi-storey residential or apartment buildings, communal areas (eg entrance lobbies and communal corridors) and facilities (eg water supply systems and fire service installations) are co-owned by individual homeowners, and all owners are jointly responsible for the management and maintenance of these shared parts (Nield, 1990; Bailey and Robertson, 1997; Yip and Forrest, 2002). However, Bengtsson (1998, 2001) and Walters (2002), founding on the game theory and concept of transaction cost respectively, expounded residents’ participation or investment in the common good with regard to building management as unlikely.
To facilitate the coordination among individual homeowners in managing the shared parts of a building, some organisation for building management is needed. The Home Affairs Department (2001) suggested the homeowners to actively participate in the matters of building management by forming statutory owners’ associations. At the same time, the homeowners can appoint external property management agents (PMAs) to manage the building on their behalf. While there is a growing body of research examining the effects of building management on building performance (eg Ho et al., 2006, 2007) and residents’ satisfaction (Paris, 2006), little work has focused on the relationship between property management and property price.
In this light, this study aims to fill up this research gap by investigating which building management practices add value to properties in Hong Kong. By means of hedonic price analysis, the transaction data of 189 apartment buildings in Hong Kong were studied. We found that property value was enhanced by practices like keeping as-built architectural drawings and incident records, taking out property-all-risk insurance for common areas, setting out emergency plans and conducting regular fire drills. The findings in this study have far-reaching practical and policy implications.
Roles of building management bodies
The significance of property or building management to building conditions and residents’ wellbeings has been well documented. Given the design and construction are up to standard, buildings are usually of good performance when newly built. As a physical asset, a property is always subject to wear and tear (Hui, 2005). Therefore, proper maintenance and management is indispensable for keeping the building in serviceable conditions (DeCarlo, 1997; Choy, 1998; Chung, 1999). To facilitate the management of multi-storey buildings in Hong Kong, the Home Affairs Department advocated the formation of incorporated owners (IO) and the appointment of external PMAs. By virtue of the Building Management Ordinance (Chapter 344 of the Laws of Hong Kong), an IO is a legal entity set up to act legally on behalf of all owners of a multi-storey building or development. Unlike other types of owners’ or residents’ associations such as owners’ committees and mutual aid committees, the formation and operations of an IO was backed up and, at the same time, bound by the ordinance and/or deed of mutual covenant (Nield, 1990). The Building Management Ordinance confers the power to the IO to enforce the resolutions made in the general owner meetings (Home Affairs Department, 2001). Besides, IO is powered to monitor the services provided by the external PMA, and terminate the service contracts if the agent does not perform satisfactorily. On the whole, the regular meetings held by the IO provide a platform for the homeowners to air grievances, and facilitate decision making on building management issues (Kent et al., 2002).
No matter whether an owners’ association exists in an apartment building or not, homeowners can appoint an external PMA to manage the building on their behalf. The responsibilities of a PMA vary across buildings, and may include provision of security and cleansing services, and assisting homeowners in convening meetings and coordinating activities (Home Affairs Department, 2001). Besides, the external PMAs are responsible for keeping up physical conditions of buildings through preventive measures and routine maintenance. They also attend to the financial wellbeing of building management structure under their charge through fiscal planning and budget controls (Fong, 1984).
Buildings with statutory owners’ associations were found to have fewer problems and better conditions for the building (Ng, 2004; Ho et al., 2006; Wan et al., 2006). Lai and Ho (2001) argued that external PMAs, with better know-how in using legal means, can help check the problem of unauthorised building works. On the contrary, a weak-principal–strong-agent situation may occur when powers are delegated to the management committee of an owners’ association or an external PMA. Although the committee members should act on behalf of their principals (ie the homeowners), they may make decisions that are beneficial to themselves at the costs of other owners (Walters and Kent, 2000). Such kind of rent-seeking behaviour is best illustrated by the proliferation of corruption cases in building management in Hong Kong. The Independent Commission Against Corruption received 978, 822 and 972 corruption reports involving building management in 2005, 2006 and 2007, respectively (The Government of the Hong Kong Special Administrative Region, 2008). Among some 2,000 private-sector corruption reports received in 2007, 40 per cent were related to building maintenance works.
Building management and property value
There has been plenty of research dedicated to the relationship between building characteristics and property price, especially in residential properties. For example, Vandell and Lane (1989) and Chau et al. (2004) discovered that properties with better designs attracted higher values. Robinson (1946) and Jimenez (1983) found that better-conditioned properties were rewarded with higher value. Nonetheless, the association between property value and building management has not been extensively investigated. Studying 15 residential developments in Hong Kong, Hastings et al. (2006) evidenced that the presence of PMA or statutory owners’ association in a building was found to be a significant predictor of property value. Lau (2005) found that the properties managed by an external PMA had value added if that agent was certified under the ISO system.
Yet, these previous studies on the value enhancement effects of building management are not free from methodological flaws. For example, Hastings et al. (2006) took building management dichotomously in the exploratory model: using whether a statutory owners’ association was formed and whether an external PMA was engaged as proxies of building management. Likewise, Lau (2005) only concerned whether the PMA was accredited by the ISO. These dichotomous definitions are misleading because even with the same building management structure, buildings could have different building management practices in place. That means the management practices or even outputs vary across buildings so it is not precise to use the existence of one particular type of building management body as the sole indicator in building management studies. Value enhancement effects of individual management practices remain to be demonstrated because it is more insightful to know that which practices are valued by the market players and which are not.
ANALYTICAL FRAMEWORK AND METHODOLOGY
As aforementioned, there is little in literature in terms of robust and detailed studies examining which management practices add values to the managed properties. In this regard, hedonic price model was adopted in this study for the exploratory analysis. According to Rosen's (1974) seminal work, hedonic price model can extract the implicit price of property attributes from property transaction prices. As such, it can be employed to estimate the value enhancement effects of various building management practices. With the loss of generality, the price of a property (P) can be expressed as a function f(.) of the physical characteristics of the property (X), management practices executed in the building (M), location-related factors (L), the time when the property was transacted (T) and unknown parameters (ϕ), or mathematically
Since the functional form of f(.) is not known a priori, a semi-log specification with quadratic terms for continuous variables was used for estimation because this functional form has been widely supported (eg Hogarty, 1975; Bajic, 1993). The generic model in Equation (1) was thus specified as:
where α s (s=1, 2, …, 18), β w (w=1, 2, …, 11) and φ (a vector of coefficients) are coefficients to be estimated, and ɛ is the stochastic term. The variables incorporated in Equation (2) are described in Table 1.
The first set of coefficients (ie α s ) measures the marginal effects of the inborn property characteristics such as building age, floor level, floor area, development scale, distance from the mass transit system and location on property price. Regarding the locational dummies, properties situated in Quarry Bay were taken as the reference location or base. All these characteristics were controlled in the model. Besides, time dummies set on a monthly basis were used to control for the possible effect of time on the variations in property transaction price because panel data on property transactions were used and market conditions might change over time. Meanwhile, the second coefficient set (ie β w ) measures the effects of marginal effects of various building management practices on property price. A total of ten building management practices were investigated in this study.
Building management practices investigated
To facilitate building management and maintenance, documentations like keeping record plans, maintaining incident records and seeking feedbacks from the occupants on building conditions are essential. For example, a complete set of updated records or as-built drawings on architectural and building services designs is useful for future maintenance and renovation (Cheng, 1998; Home Affairs Department, 2001). It provides details of the systems used in a building, such as the capacity of its electricity supply system and the routing of its cables. This can make decision making during emergency maintenance easier. Also, record drawings are solid references for identifying unauthorised building works and other irregularities in a building.
In addition, keeping track of these incidents such as falling building fabrics, fires, and interruptions of power supply is advantageous for the homeowners and property managers of a building. A similar attitude towards the importance of incident records has been widely shared by researchers in the field of occupational safety (eg Koornneef and Hale, 1997; Hakkinen, 1999). The analyses based on these incident records provide building stakeholders with insights into the aspects of building management that warrant more attentions, and valuable information for property managers to prioritise improvement works.
As for residents’ feedbacks, they are essential for the evaluation of the work of the building management bodies. Very often, the feedbacks in residential premises are obtained systematically from occupant surveys, which provide a formal channel for occupants to give comments to management. This evaluation mechanism is important for the continuous improvement of building performance (Zimring and Reizenstein, 1980). Upon observing and addressing the comments in the surveys, the management bodies concerned can help raise the satisfactory level of occupants and the conditions of the building.
Apart from documentations, emergency preparedness is another critical aspect of building management because we need to ensure that management is able to react calmly, and all occupants are able to evacuate orderly to safety in case of an emergency (Malhotra, 1987). To enhance the emergency preparedness of the management body in a building, an emergency or contingency plan should be formulated (Carighead, 2003). An emergency plan sets out what the building management body should do in the event of an emergency, and how they should handle and recover from it (Egbuji, 1999). At the same time, residents of an apartment building should familiarise themselves with the direction and routing of the means of escape in buildings and always be prepared for a quick evacuation (Information Services Department, 1997). This issue should not be ignored because buildings designed and constructed with excellent means of escape do not guarantee that their occupants would know where the exits are located. To aid in the familiarisation, evacuation plans should be provided to occupants and/or posted in conspicuous positions in the buildings. Besides, regular fire drills are indispensable to provide training or rehearsal to occupants (Home Affairs Department, 2001).
Lastly, building management system relies on the availability of financial resources for emergencies to be effective. For instance, it is very difficult to raise or collect money from every individual homeowner for the cost of emergency repair works in common areas of a building. Therefore, the availability of sinking fund in a building reduces the response time for emergencies and unexpected circumstances, guaranteeing the future upkeep of a building. Similarly, the Home Affairs Department (2001) recommended building management bodies to take out third-party liability and property-all-risk insurances for the common parts of their buildings. The first type of insurance indemnifies the homeowners from claims for compensation and associated legal costs as a result of personal injury to or the death of a third party caused by the negligence of the insured while the second type usually covers losses or damages to the common parts or facilities of a building due to fire, storm, flood or other malicious acts. With a view to lower premiums for the insurances, the homeowners are self-motivated to keep their buildings in serviceable conditions.
Since it is widely accepted that the building management practices investigated in this study have positive impacts on the building conditions, we envisage that these practices would be positively valued by the market players. Along this line of thought, we hypothesise that all coefficients β w (w=1, 2, …, 11) should be statistically significant and positive.
The investigation of the effects of various building management practices on property price was made possible with the Building Health and Hygiene Index and Building Safety and Conditions Index research projects funded by the Research Grants Council and the University of Hong Kong. In the two projects, the details of which can be found in Wong et al. (2006) and Ho et al. (2008), apartment buildings in Hong Kong were benchmarked with reference to their health and safety performance using a tailormade assessment framework. The assessment covered different quality aspects, namely architectural design, building service provisions, external environment, operations and maintenance, and management arrangements. Therefore, information regarding the management practices in the assessed buildings is available for data analysis in this study.
In total, data of 189 apartment buildings in the Yau Tsim Mong and Eastern Districts assessed in 2004 and 2005 respectively were used for this study. There were altogether 3,057 transactions in the 189 buildings between January 2002 and December 2005. Information on the transaction prices and particulars of the transacted properties (eg age, floor level and floor area) was obtained from the Economic Property Research Centre. Descriptive statistics of the continuous variables are described in Table 2.
ANAYLSIS RESULTS AND DISCUSSION
The estimation results of the hedonic price analysis are shown in Table 3. The adjusted R-squared was about 0.74, indicating that about 74 per cent of the variations in property prices could be explained by the variations in the dependent variables. We found that all the control variables, namely AGE, FLOOR, SIZE, UNIT and MTR, had significant (at least at the 10 per cent level) non-linear effects on the transaction prices of the properties under investigation. Except for North Point, transaction prices in all districts deviated significantly with those in Quarry Bay, ceteris paribus.
As for the ten building management practices, six of them were found to significantly affect property prices. Keeping general building plans added 12.9 per cent premium to the concerned properties (significant at the 1 per cent level). Properties in buildings covered by property-all-risk insurance policies were sold at a price 3.6 per cent higher than those uncovered (significant at the 5 per cent level). Besides, 7.5 (significant at the 1 per cent level) and 2.1 per cent (significant at the 10 per cent level) of value were added to the transacted properties if incident records were documented and emergency plan was set out, respectively. Moreover, the analysis results indicate that the frequency of regular fire drills had a positive relationship with the property price (significant at the 10 per cent level), given that it exceeded 0.56 time per month. All the results above confirm with our expectations. Nevertheless, practices like provision of fire safety plan to the residents, taking out of third-party liability insurance, availability of sinking fund and regular resident surveys did not have any significant impacts on the property transaction price. Moreover, it is difficult to explain why properties in buildings with building services plans documented were generally sold at a 5 per cent discount (significant at the 1 per cent level), ceteris paribus.
Based on the empirical findings, we may conclude that not all building management practices currently adopted are positively valued by the housing market. The analysis results give practitioners insights into which management practices are valued most by the market players, helping them to formulate better business strategies. Also, if the value enhancement through the building management practices is well publicised in the society, a building care culture can be fostered by market forces. Homeowners are more willing to practice building management in their buildings with a view to the premium added to the value of their properties. On the other hand, warning signals are given to the public administrators if some management practices are considered essential by the government but were found to be insignificant determinant of property price. A gap exists between the government's aspirations and the market's valuation, and more resources should be directed to the education and promotion campaigns about the importance of these ‘undervalued’ practices. Alternatively, the government may need to think about making these practices mandatory or subsidising them.
Yet, some precautions should be taken in interpreting the relationships between property prices and building management practices. In spite of the wide varieties in the inborn characteristics of the buildings (eg age and development scale) under study, only properties in those buildings with transaction records were included in the sample. In fact, a total of 323 apartment buildings were assessed in the Building Health and Hygiene Index and Building Safety and Conditions Index projects. However, those buildings badly dilapidated had no transactions during the target study period so they were not included in the sample. In other words, potential sample selection bias may limit the generalisability of the research findings.
Although many people thought that buildings managed by owners’ associations and/or external PMAs should perform better, Walters and Kent (2000) posited the opposite because the committee members in the owners’ associations and the external PMAs tended to make decisions which were beneficial to themselves. Other than these agency problems, building management and maintenance is sometimes hindered by the inactive owners’ association (Housing, Planning and Lands Bureau, 2005). Worse still, rivalry may exist within owners’ associations (Housing, Planning and Lands Bureau, 2004) or between homeowners and external PMAs. This will only worsen rather than relieve the building management problems. In this light, simply using the formation of owners’ association and appointment of external PMA as proxies for building management in empirical analyses could generate misleading results. Against this background, we offered a preliminary study on the property-value enhancement effects of various building management practices in Hong Kong. We found that practices such as keeping as-built architectural drawings and incident records, taking out property-all-risk insurance for common areas, setting out emergency plans and conducting regular fire drills added value to properties.
The analysis results give market players, housing management practitioners and public administrators’ insights into which management practices are valued most by the market. Regardless of the valuable insights provided, this study should be regarded only a starting point for studying this research topic. Further research is recommended to explore how the levels or dimensions of building management practices affect property value. To put it another way, management practices under investigation in this study were taken as dichotomous variables so information of their dimensions was ignored. In fact, explanatory factors such as TPL and PAR can be represented or measured in some other dimensions. For instance, instead of simply considering whether insurance policies have been taken out or not, we can look into the value of insurance coverage. It is a similar situation for the sinking fund. As a result of this adjustment, we can how the value enhancement effects vary with the value of the insurance cover or sinking fund. Moreover, the value enhancement study can be extended to cover management practices such as implementation of planned maintenance and cleansing of public areas.
