Required Documents for Development Application: Residential Development – New Home (Dwelling)
When seeking council approval to construct a single dwelling (house) in NSW, a detailed Development Application (DA) must be prepared to demonstrate compliance with local planning standards, environmental laws and community expectations.
Building a standalone residence requires thorough planning to address site-specific conditions, design integration with the surrounding area and adherence to safety and environmental sustainability guidelines.
Below is a breakdown of the essential documents typically needed for this type of development.

Statement of Environmental Effects (SEE)
The Statement of Environmental Effects (SEE)Â is a critical component of any DA, outlining how the proposed development will affect the local environment, community and infrastructure.
For single dwellings, the SEE should address elements such as the size, design and placement of the house on the lot, its compatibility with neighbourhood character and any measures to mitigate potential impacts like overshadowing, noise or privacy concerns.
Additionally, the SEE should discuss how the development protects local flora and fauna, particularly if the site includes mature trees or environmentally sensitive areas.
Site Analysis and Design Report
A Site Analysis and Design Report provides a detailed overview of the property’s characteristics and explains how the proposed house is designed to harmonise with its surroundings.
This report typically includes information about the site’s orientation, natural features such as slopes or vegetation and proximity to neighbouring properties.
The design section demonstrates how the dwelling complies with local planning controls, considering factors like solar access, setbacks and integration into the existing streetscape.
Survey Plan
The Survey Plan is essential for accurately defining property boundaries, topography and any easements or restrictions that may affect construction.
This document identifies the exact location and dimensions of the proposed home, ensuring compliance with boundary setbacks and local zoning laws.
Councils use the Survey Plan to verify that the placement of the new house aligns with planning requirements and avoids encroaching on neighbouring properties or easements.
Architectural Plans
Architectural Plans detail the design and layout of the proposed dwelling, including floor plans, elevations, sections and roof layouts.
These drawings provide insights into the internal and external features of the home, such as room arrangements, material choices and window placements.
Councils review these plans to ensure compliance with building codes, zoning laws and aesthetic guidelines, ensuring the design is appropriate for the local character.
Landscape Plan
The Landscape Plan demonstrates how the property’s outdoor spaces will be designed to enhance visual appeal, support environmental sustainability and provide functional green areas.
This plan should detail proposed plantings, tree retention or removal , fencing and hardscaping features like patios or pathways.
Councils use this document to assess whether the landscaping integrates with the neighbourhood and meets requirements for biodiversity and green space.

Stormwater and Drainage Management Plan
A Stormwater and Drainage Management Plan is crucial for ensuring the property effectively manages rainwater runoff.
This document outlines how water will be collected, treated and directed on-site to prevent issues like flooding or erosion.
Councils assess these plans to confirm that the development includes appropriate infrastructure, such as rainwater tanks, drainage systems or retention basins, to protect neighbouring properties and maintain water quality.
Erosion and Sediment Control Plan
An Erosion and Sediment Control Plan is often required for sites where ground disturbance will occur during construction.
This document outlines strategies to prevent soil erosion and manage sediment runoff, such as using sediment traps, silt fences, or temporary ground covers.
Councils use this plan to ensure the construction process minimises environmental impact and protects nearby properties and waterways.
Additional Reports and Requirements
In certain situations, councils may request additional documentation to address specific challenges posed by the site’s location, environmental features or design complexity.
Bushfire Attack Level (BAL) Assessment
Properties in bushfire-prone areas require a BAL Assessment to determine fire risk levels and recommend measures such as using fire-resistant materials or creating buffer zones around the dwelling.
Geotechnical Report
For sites with challenging soil conditions or significant slopes, a Geotechnical Report assesses soil stability and outlines foundation reinforcement strategies to ensure structural safety.
Arborist Report
If mature trees are located near the construction area, an Arborist Report evaluates their health and provides recommendations for preservation or removal, ensuring compliance with local tree protection rules.
Flood Risk Assessment
For properties in flood-prone areas, a Flood Risk Assessment evaluates hazards and proposes mitigation strategies, such as elevating the dwelling’s floor level or improving drainage.
Acoustic Report
Homes located near high-noise areas, like highways or railway lines, may require an Acoustic Report to identify soundproofing solutions such as insulated walls or double-glazed windows.
Heritage Impact Statement
If the property is in a heritage conservation area, a Heritage Impact Statement will assess how the proposed dwelling affects the historical and architectural significance of the site and suggest design modifications to preserve the area’s character.
Environmental Sustainability Report
Some councils may request an Environmental Sustainability Report detailing eco-friendly features of the home, such as solar panels, water-saving systems, or energy-efficient appliances. These features help align the development with broader sustainability goals.
By thoroughly preparing these documents, you can ensure your single dwelling project complies with all relevant planning controls and progresses smoothly through the approval process.
Partnering with experienced town planners can streamline the process, ensuring every detail is handled professionally and efficiently.
