When is a Development Application (DA) Required?
A Development Application (DA) to Mosman Council is necessary for new dwellings, dual occupancies, secondary dwellings (granny flats), townhouse developments, residential alterations or additions, small commercial projects, and changes of use for businesses such as local cafes, restaurants, or shops.
Determining whether your development requires a DA involves considering several planning documents specific to Mosman, including:
State Environmental Planning Policy (Exempt and Complying Development Codes) 2008
Mosman Local Environmental Plan 2012
Mosman Residential Development Control Plan 2012
Given Mosman's unique residential character, strong emphasis on heritage conservation, and sensitivity to issues like view preservation and tree management, it’s crucial to clearly establish your project's compliance and suitability from the outset.Planna’s Preliminary Planning Report (PPR) provides a clear assessment of relevant local planning controls, identifies potential site constraints, and evaluates development pathways—ensuring you clearly understand the feasibility and likelihood of obtaining council approval before proceeding further.
Mosman Council has a detailed and rigorous development assessment process due to strong community expectations around design quality, heritage preservation, streetscape appearance, and view protection. Once the preliminary planning assessment is completed, your next step is preparing a thorough Statement of Environmental Effects (SEE). This document explains how your proposal aligns with Mosman’s specific planning requirements, carefully addressing potential impacts on privacy, visual bulk, view sharing, heritage considerations, and landscaping.Given Mosman’s significant heritage areas and sensitive landscapes, the SEE may also need specialist inputs such as heritage assessments, arborist reports, or view impact analyses. Planna specialises in preparing detailed, site-specific SEE reports tailored precisely to Mosman Council’s planning expectations. By clearly justifying your development and demonstrating thoughtful integration within Mosman's established character, Planna ensures your DA moves efficiently through council assessment toward successful approval.
