Section 1
Consent, policy and location
Current development plan and policy hierarchy
What current plan documents and retained policies does the authority say form the development plan, and how should conflicts or transitions be handled?
Bristol City Council's current Local Plan page identifies the Core Strategy, Site Allocations and Development Management Policies, Bristol Central Area Plan and West of England Joint Waste Core Strategy as adopted development-plan documents.
- When this answer applies
- Identify which city-wide, central-area, waste, site-allocation, neighbourhood-plan and mapped policies apply before assessing a proposal.
Details and exceptions
- The emerging new Local Plan is not yet an adopted replacement; its weight and any later adoption must be checked at the application date.

Section 2
Neighbour amenity
Daylight, sunlight, overshadowing and overbearing impact
How does the authority assess daylight, sunlight, overshadowing and overbearing impact?
Policy DM30's supporting text says extensions should avoid harmful loss of sunlight or daylight through overshadowing and should not be overbearing or cause unacceptable overlooking or loss of privacy.
- When this answer applies
- Relevant where an alteration or extension could affect neighbouring windows, rooms or outdoor space.
Details and exceptions
- The adopted policy states an effects-based test rather than a universal 45-degree measurement; apply the current detailed householder design guide and the site's geometry and orientation.

Extensions
What does the authority say about design and dimensions for front, side, rear, single-storey and multi-storey extensions?
Policy DM30 requires extensions and alterations to respect the host building, curtilage and street scene, retain distinctive fabric, safeguard occupiers' amenity, leave usable private space and remain physically and visually subservient to the host building.
- When this answer applies
- Applies to extensions and alterations to all building types that require planning permission.
Details and exceptions
- Householder proposals should also use the council's current detailed extension guidance and any heritage or neighbourhood-plan requirements.

Residential quality and housing form
Subdivision and flat conversion
What does the authority say about subdividing dwellings or converting buildings to flats?
Policy DM2 resists subdivisions, HMOs and shared or specialist housing where activity, noise, parking, physical alterations, waste or cycle-storage effects harm residential amenity or character, or where the use would create or add to a harmful local concentration.
- When this answer applies
- Relevant to dwelling subdivisions, new or intensified HMOs, specialist student housing and other shared housing.
Details and exceptions
- The concentration assessment considers street, neighbourhood and ward evidence and the proposal must also provide a good standard of accommodation under the other plan policies.

Flooding, environment and climate
Flood risk and the sequential approach
What does the authority say about flood zones, sequential and exception tests, vulnerability, levels and resilience?
Policy BCS16 applies the sequential approach, prioritising lowest-risk sites, and requires development in flood-risk areas to be safe over its lifetime through resilient design, layout and necessary on- or off-site mitigation.
- When this answer applies
- Relevant to development in flood-risk areas and to unallocated sites requiring a sequential test under current national policy.
Details and exceptions
- The policy cites superseded national guidance; apply current national policy, current flood maps, climate allowances and the latest strategic flood-risk evidence.
Sources used
- Bristol Development Framework Core Strategy (opens in a new tab)Development plan— Policy BCS16 and paragraphs 4.16.1–4.16.8, printed pages 104–106
Drainage and sustainable drainage
What does the authority say about surface-water hierarchy, runoff, attenuation, SuDS, adoption and maintenance?
Policy BCS16 expects all development to manage surface water so flood risk is not increased elsewhere and to use sustainable drainage; the supporting text calls for the optimal site approach to be explained in a SuDS strategy within the Sustainability Statement.
- When this answer applies
- Relevant to development that changes surface-water runoff.
Details and exceptions
- Detailed runoff rates, drainage hierarchy, maintenance and adoption arrangements must use current lead-local-flood-authority and sewerage guidance.

Policies BCS17 and DM3 set geographically varied affordable-housing targets: BCS17 addresses schemes of 15 or more homes, while DM3 addresses schemes of 10 to 14 homes and allows on-site or, where impracticable, equivalent financial provision.
- When this answer applies
- Relevant to residential development reaching the policy thresholds, with tenure, size and type informed by need, site suitability and viability.
Details and exceptions
- Before relying on the plan-era thresholds or percentages, check current national policy, written ministerial statements, any current council practice note and the status of the emerging Local Plan.
- A lower or different contribution based on viability requires a full development appraisal for independent validation.

Section 106 and infrastructure contributions
What does the authority say about planning obligations, infrastructure contributions, calculation and delivery?
Policy BCS11 coordinates development and infrastructure, using planning obligations for direct mitigation and CIL for infrastructure supporting growth; obligations may be sought from development of any size where an impact requires lawful mitigation.
- When this answer applies
- Relevant where a proposal creates an infrastructure, service or facility impact that satisfies current statutory tests.
Details and exceptions
- The mechanism and amount depend on current CIL charging, section 106 law, the live infrastructure programme and the proposal's specific impacts.

Application evidence and validation
Heritage and archaeology evidence
What does the authority say about when heritage statements, impact assessments, appraisals and archaeological evidence are required?
Policy DM31 requires proposals affecting heritage assets to demonstrate a thorough, proportionate understanding of significance and the effect of change; archaeological work can require assessment, evaluation, excavation, recording, publication and curation.
- When this answer applies
- Relevant to designated and locally important heritage assets, archaeology, conservation areas, registered parks and gardens and their settings.
Details and exceptions
- The appropriate evidence depends on asset significance and impact; consult the Historic Environment Record and current national heritage policy.

- Site Allocations and Development Management Policies Local Plan (opens in a new tab)Development plan— Policy DM31 and paragraphs 2.31.1–2.31.9, printed pages 64–68
Trees, landscape, ecology and BNG evidence
What does the authority say about when tree, landscape, ecological, protected-species and biodiversity-net-gain evidence is required?
Policy DM19 requires a suitable survey and impact assessment where development is likely to affect habitats, species or nature-conservation features, with harm avoided where practicable and viable, connections retained and on-site or off-site mitigation provided where loss remains.
- When this answer applies
- Relevant to designated sites, wildlife corridors, protected or priority species and habitats, and other nature-conservation features.
Details and exceptions
- Survey timing and scope must be appropriate to the species and current legislation; mandatory biodiversity net gain is a separate current statutory requirement where applicable.

Ground and pollution evidence
What does the authority say about when contamination, stability, noise, vibration, air-quality, odour and lighting evidence is required?
Policy DM34 requires contamination to be addressed so the site is suitable for its proposed use and no unacceptable pollution risk remains; known, suspected or sensitive sites normally need at least a desk study and site walkover, with investigation, risk assessment and remediation added where indicated.
- When this answer applies
- Relevant to development on or next to potentially contaminated land, sensitive uses and proposals that could contaminate land.
Details and exceptions
- The investigation must follow a risk-based source-pathway-receptor approach and current environmental-health guidance.
