The client and informal construction workers enter into verbal agreements without any legal enforcement for the proposed construction. This research study aimed to evaluate administration of agreement practice between clients and informal construction workers in the informal construction sector through an identification and assessment of the kind of work agreement between clients and informal construction workers present in the informal construction sector, to identify and assess source of disputes arising out of the agreements between the clients and informal construction workers in the informal construction sector and suggest possible measures so as to improve work agreement in the informal construction sector in Tanzania. Purposive non-probability sampling was used to obtain sample of the study which indicates prevalence of the population and convenient non-probability sampling to enable ease of accessing construction sites around the area. A total of 60 informal construction workers and 10 clients from Goba and Madale in Kinondoni Municipal were drawn as the sample of this study and structured and unstructured interviews were used as a means of collecting data. All findings collected were analyzed through tables and graphs. Findings revealed that work agreement in the informal sector does not include express terms which clearly describes each and every party’s duties and obligations for performance of the contract. It is simply a negotiation which involves verbal agreement on work to be performed for a certain duration of time and payment involved. The study recommended that it is best for the work agreement between the parties to be documented clearly describing each and every party’s duties and obligations for performance of the contract and legally binding for its success.
