● Public sector — Planning assessment

The AI assistant for the planning permission case officer

Every day you check applications against the local plan, verify that the documents are complete and spot inconsistencies before the statutory deadline. Your AI agent connects to your case management software and prepares that analysis, file by file. Hosted in France — on local inference or an isolated resource — your planning files stay under public control. You keep the decision and the signature.

On the prior notification DP-2026-118 (extension + garden shed), check the project against the local plan and flag the missing documents.
File analysed. The extension takes the floor area to 178 m²: zone UB, projected site coverage 41% against a regulatory ceiling of 40% — an excess to check. The garden shed (9 m²) stays below the notification threshold. Missing documents: the elevations drawing (DP4) and the graphic insertion (DP6) are not in the file.

✦ In brief

In a planning authority (local council, inter-municipal body or state service), a Blue Lemon Agent agent assists the assessment of planning applications — checking against the local plan and the easements, verifying that files are complete, flagging inconsistencies. It is configured on your own local planning documents. It runs on local inference or is hosted in France: the case data is never exposed to a foreign service, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. The agent prepares the analysis; the decision and the signature remain with the competent authority. Live within a few weeks. Your public-sector staff write to it from Microsoft Teams, Slack or their email, and planning applicants reach it on WhatsApp Business, the website chat or email — with no account to create and nothing to install. Reaching the administration from the tool people already have means less non-take-up of rights and equal access to the service. These connections are included in every plan, at no extra cost, within the number of connections your level includes.

The context

Why AI matters to assessment services — and why they hesitate

Assessment periods are set by law, planning documents keep growing more complex, and applicants expect quick, even-handed treatment. But the time available is mechanically eaten up by checking documents and comparing against the rules — and the data handled belongs to the public service.

! The issue

The planning team is caught between statutory deadlines to meet (building permits, prior notifications) and an analysis load that keeps growing: the local plan, easements, the documents in the file, mandatory consultations. Yet most consumer AI solutions amount to entrusting planning case data, information about plots and applicants to a third party, often hosted outside Europe and subject to the Cloud Act.

Our answer

For a public service, AI is only of interest if it is sovereign and confidential by design. Local inference or an isolated resource hosted in France, systematic human oversight, decisions reserved to the competent authority: the time saved on pre-assessment is never paid for in lost sovereignty. The aim is not to replace the officer, but to give them back time to make their decisions safe and to guarantee equal treatment between applicants.

The decisive point

Planning data: sovereignty & compliance

A planning authority handles data that belongs to the public service and that determines rights. Here is how the architecture of our agents protects it, file by file.

Local inference

The agent can run on a machine at the service: no document from a file leaves the network, nothing passes through a cloud.

Hosting in France

Otherwise, a dedicated and isolated resource, hosted in France under French law — your data: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

Architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity for the case data: our architecture depends on a subcontracting chain and remote access documented for the configuration chosen.

One isolated resource per authority

No pooling of data: an environment strictly dedicated to your case-handling department.

Encryption & controlled access

Encryption in transit and at rest, role-based access (RBAC), strong authentication and logging.

AI Act: governed deployment

The agent is strictly in support; no automated decision on rights; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • The encryption mechanisms in transit and at rest, their components and key management are those documented for the architecture chosen.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For the most sensitive data, SecNumCloud and HDS options are available depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
Demonstration

See the agent at work

5 real situations, taken from those that come up most often. Pick one: the exchange unfolds as it would in your organisation.

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

The public body in this demonstration

Fictional public body

Portes du Vexoncé community of municipalities — shared planning assessment service for 31 municipalities

Sector
Fictional authority — shared assessment service: minor works declarations, building and development permits, planning certificates for the 31 member municipalities, which keep the decision and the signature
Headcount
6 staff in the service — 4 case officers, a head of service and an assistant who runs the front desk and filings; each officer carries about 335 files a year
Public served
46,000 residents and 31 municipalities — applicants who are most often private individuals filing one application in their lifetime
Order of magnitude
1,340 files a year — 890 minor works declarations, 310 building permits, 40 development permits, 100 operational planning certificates — and 2,900 applicant questions
Tools in place
Assessment software, online filing platform, document management system and 31 planning documents — 15 local plans, 9 municipal maps, 7 municipalities under national rules; the agent plugs into them read-only, nothing is replaced and nothing is migrated
Who decides
The case officer settles the opinion; the decision and the signature belong to the mayor of the municipality concerned; the head of service approves every go-live; the Architect of the Buildings of France gives an opinion on projects within a protection perimeter
Room for improvement
11 files became tacit approvals last year for want of an answer within the deadline, 3 of them on projects the municipality would have refused; 27 requests for missing documents went out after the first month; 46 % of files arrived incomplete; and an applicant's question waited 6 days for its answer

At Portes du Vexoncé, four case officers carry 1,340 files a year across 31 municipalities that do not share the same planning document: fifteen local plans, nine municipal maps, seven municipalities under national rules. The statutory deadline runs from the moment of filing, and it does not stop. The agent runs on local inference on a machine of the service, reads the 31 planning documents, the easements and the eight years of files without ever writing to them, and lets nothing leave without a case officer's approval. The exchanges that follow span one year, from the reading of the planning documents to the review presented to the mayors.

This public body, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real service.

Planning assessment assistant · hosted in France
I read your thirty-one planning documents and your eight years of files over the weekend — 9,840 applications assessed, 15 local plans, 9 municipal maps, 7 municipalities under national rules — and I draw from them three findings your cabinets carried without anyone ever having the time to see them.
The applicant is the person who files the application; preliminary assessment is the preparatory work that checks the project against the applicable rules, before the case officer takes a view.
The first finding, and it is the one that exposes you most: 11 files became tacit approvals last year for want of an answer within the deadlineonce the deadline stated on the receipt has passed, silence from the administration creates an authorisation: the file is not rejected, it is granted. Of those 11, 3 concerned projects the municipality has confirmed to me it would have refused. These are not badly assessed files: they are files whose due date was written nowhere but in someone's head.
The second: 27 requests for missing documents went out after the first monthyet it is within that first month that such a request has its effect on the deadline; after it, the clock keeps running on the file as it was filed. 27 times, the service asked for a document without being able to stop the clock.
The third: 3 of your written rulebooks are not up to date with the last amendment voted by the municipality — two simplified amendments and one limited revision, adopted and never carried into the document your officers open. I found the three resolutions, and I set the old article and the voted article side by side.
What I propose, and it is not a promise — it is already in place: every file in your software now carries its calculated due date, and the alert falls ten days ahead. Running last year's 1,340 files through that calculation, the 11 tacit approvals would all have been flagged between 34 and 12 days before the deadline.
What that moves, measured on your own records: the full preliminary assessment of a standard minor works declaration takes 50 minutes here — that is the reference for my three figures. It goes from 100 % to 18 % of that time: from 50 minutes to 9.
The next step, and it takes half a day: your head of service reviews the three rulebooks I have brought up to date, municipality by municipality, and the deadline alert goes live the same evening. The decision and the signature stay with each municipality's mayor — and I hand them to him ten days before the deadline, file complete and reasoned. planning-documents_31-rulebooks-3-updated.pdf31 rulebooks indexed, 3 updates found, 11 tacit approvals explained
⛓ Sourced · 31 planning documents, 8 years of the service's files, municipal resolutions register, filing receipts
Our case officers spend endless time finding what has already been decided on a plot or on a similar case. It is all in the files, and nobody knows where.
Eight years of files are indexed on their content, and a search that took twenty minutes takes forty seconds — let me show you on a real case from the service.
What I bring up when an officer opens a plot:
· Every permission granted on that plot and on the adjoining plots since 2018, with its object, its date and the outcome.
· Refusals, with their full reasoningthe most useful and the hardest document to find, because a refusal reasoned on a precise point sets the service's position for every similar file.
· Comparable files from the 31 municipalities: same zone, same nature of works, same constraint. On an extension in a development zone with an excess of ground coverage, I bring you the 34 comparable files of eight years and the outcome retained each time.
· The 14 legal challenges the service has known in eight years, with the ground the court retained in each. 9 of the 14 turned on reasoning found insufficient, never on the substance of the judgement. That is the most profitable lesson in your archives, and it was written nowhere.
What I do with it, and nobody has the time to do: I took the 9 censured statements of reasons and drew from them a six-point reasoning template, which I ran over the 212 refusals issued in eight years: 178 already met it, 34 did not — and those 34 are exactly the profile of the files that were challenged. The template is written, it fits on one page, and every draft decision I hand you now follows it.
Equal treatment, since that is what an applicant challenges first: the same file lodged in two municipalities under the same rulebook receives the same analysis, because it is the same reading that applies. Across the 34 comparable files I found 4 divergences of judgement between officersthey are handed to you as they are, with both positions and the number of files concerned, and it is the service that settles its own.
The next step I propose: that every new file arrive with its plot history and its comparables already attached. Over the trial quarter that represented 84 officer hours no longer spent searchingand an officer deciding on the service's 34 precedents rather than on memory. service-memory_plots-comparables-and-reasoning.pdf9,840 files indexed, 14 challenges analysed, six-point reasoning template
⛓ Sourced · 8 years of assessed files, permissions register, refusal decisions and their reasoning, the service's litigation files
All this assumes you read our files: plans, addresses, applicants' names, sometimes family situations. Where does that data go?
It goes nowhere. I run on local inference on a machine of the service, and no file document leaves the community's network.
Local inference means the model computes on your machine: the site plan, the applicant's name or the land registry reference never cross an outside network to be processed. If the service would rather not host a machine, the other route is an isolated resource hosted in France, dedicated to Portes du Vexoncéno pooling with another assessment service.
What that changes, point by point:
· Your file documents train no model, neither ours nor a third party's.
· I work read-only on the assessment software, the filing platform and the document management system, and the technical account through which I read has no write permissionthat is sturdier than a promise, because it is checked with one command.
· Encryption in transit and at rest, strong authentication, and role-based accessrights follow the job: the front-desk assistant opens filing schedules, not the opinions of consulted bodies. 5 roles for your 6 staff, and the log shows 0 out-of-role access since go-live.
· Hosting in France, under French law, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
· Logging: which file was analysed, when, against which article of the rulebook, and what the system produced. It is that log that will let you answer an applicant asking how their file was examined.
One thing I do in no circumstances, and I give you the route that renders the same service straight away: I take no decision on an applicant's rights. A decision producing legal effects on a person cannot rest on automated processing alone — that is a firm principle of European data protection law, and it applies particularly to a planning permission. What I do and what renders the same service: I hand over the fully reasoned draft decision, article by article, in four minutesand the case officer, then the mayor, need only read and sign. It is that signature that makes the decision challengeable before the administrative court, therefore defensible: a decision nobody had signed could be challenged by nobody, and would be worth nothing.
The figure that sums all this up: 0 file document left the service's network across the 1,340 files of the year, and processing in the EU targeted.
What I propose: that I maintain the record your data protection officer will ask for — hosting, data processed, retention periods, who accesses what. It is requested once a year and takes two days to rebuild; the first version is already written and attached. technical-framework_where-planning-files-live.pdfLocal inference, read-only, processing in the EU targeted

Our commitment

Four guarantees that matter to an assessment department

The case data never leaves the unitLocal inference or an isolated resource hosted in France; no document entrusted to a foreign third party.
Data in France, under French lawFor the case data: hosting under French law, native minimisation, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.

Human oversight & traceabilityAssessment of planning applications: monitoring, updates and logging, compliant with the requirements of the AI Act.
Frequently asked questions

Your questions, our answers

Does the agent grant the planning permission?
No. It prepares the analysis: comparison against the local plan, completeness check, flagging of inconsistencies and briefing notes. The decision and the signature remain with the competent authority. The AI agent assists, the public officer decides.
Does it adapt to our own local plan?
Yes. The agent is configured on your planning documents: the local plan rules, the zoning, the easements and the service's internal procedures. It reasons on your local rules, not on a generic reference.
What is its status under the AI Act?
Strictly a support use, with no automated decision on citizens' rights. Human oversight is systematic and every analysis is recorded. The assessment and the decision remain the work of a public officer.
Is the case data protected?
Yes. Planning case data belongs to the public service: our agents run locally at the service or are hosted in France, with the deployment objective of processing and access operated within the European Union and an architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
Does the agent guarantee equal treatment between applicants?
That is one of its contributions. By applying the same completeness check and the same comparison against the rules to every file, it reduces differences in treatment. The final decision, with its reasons, remains the officer's, who ensures fairness.
Do we have to change our case management software?
No. The agent connects to your existing tools (case management software, online filing platform, document management) and complements them, with no migration imposed. We adapt the integration to your environment.
How long does it take to deploy an agent?
A few weeks as a rule, after a free audit that identifies the most profitable use case, then a phase of design, configuration on your planning documents and testing before going live and training the officers.
Which tools can planning applicants use to reach the agent?
The ones they already have. The agent answers on WhatsApp Business, the website chat and email: an applicant has no account to create and no application to install. The documents to provide and the progress of an application can be asked about from a phone, which saves many trips to the department; the assessment and the decision stay with the case officer and the competent authority. This is a lever for access to the service — WhatsApp and the telephone reach people an online form never does, which reduces the non-take-up of rights and serves equal access. Internally, your public-sector staff talk to the agent from Microsoft Teams, Slack or their email, without switching tools. Oversight runs from a web dashboard. These connectors rely on open standards, including the MCP protocol; they are included in every plan, at no extra cost, within the number of connections your level includes. Only the fees charged by the platforms themselves — WhatsApp Business bills per conversation — are passed on at actual cost, with no margin, outside the subscription.
