Power lines, being a man-made environmental contaminant in residential
neighbourhoods, is via the regression model, incorporated into the environmental factor
considered germane in rent determination within the metropolitan and suburban parts of
Lagos. By the use of two different questionnaire surveys distributed to registered estate
surveyors and valuers (in Lagos metropolis) and residents within powerline blighted
neighbourhoods, the study unearthens the negligible effect of power lines in the
determination of rental values within metropolitan as against a nill effect in suburban
areas after collected data were subjected to regression analysis. The study recommends
prompt need of the Federal and State governments in empowering the Power Holding
Company of Nigeria (PHCN) in eliminating this negligible effect by observance of Right
of Ways (ROWs).
