Permit Calendar: Lake Como, Day by Day

Why a dated calendar#

A dated calendar is the cheapest proof of execution capacity that an allocator can ask for, and almost nobody publishes one. Lake Como schemes are usually described in the language of ambition. Very few are described in protocol numbers, filing dates and opinion dates. Yet the permit file is the one document in a restoration thesis that is produced by third parties, stamped by public bodies and dated by law. It cannot be flattered.

This paper reconstructs the calendar from the statutes, not from anecdote. It covers the ordinary autorizzazione paesaggistica under Article 146 of D.Lgs 42/2004, the simplified track under DPR 31/2017, and the permesso di costruire under Article 20 of DPR 380/2001, read for a lakefront intervention in Lombardy. It names each body, the day on which its clock starts, the term the law gives it and the events that stop that clock.

The companion paper on the landscape constraint covers the stack of layers. This one covers only time. The 300-metre band under Article 142, the regional plan and the municipal regolamenti are set out there. Here the question is narrower. In what order do the bodies act, how many days does the law allow each of them, and what does the sum come to before any clock is stopped? The answer is a ceiling, and a ceiling is a useful thing to hold.

One caveat governs everything that follows. The statutory terms below are measured in the plain sense that they are written in law. The durations that projects actually take are not measured in any public dataset we could find for the lake. Wherever this paper speaks of actual duration it says industry estimate, and it says so every time. The reader should treat the theoretical calendar as the fastest lawful path and nothing more.

Day 0 to day 40: the comune#

The calendar starts at the comune, not at the Soprintendenza. In Lombardy, Regional Law 12/2005 attributes the landscape authorisation function to municipalities and unions of municipalities (Article 80) and requires the authority to set up a commissione per il paesaggio (Article 81). The application is lodged with the comune on whose territory the villa stands. Day 0 is the date the application is received, and every later term is counted from a date that the file must be able to prove.

Within 40 days of the application the comune must do two things. Under Article 146, paragraph 7, it verifies the conformity of the intervention with the landscape plan, and it sends the documentation to the Soprintendenza with a reasoned proposal. In the ordinary track the opinion of the local commission is acquired inside that window. Under the regional law that opinion is mandatory but not binding on the comune. The commission's meeting calendar therefore sits inside the 40 days, not beside them.

The completeness check is where the first clock can stop. The Soprintendenza verifies that the file meets the national documentation standard (the DPCM of 12 December 2005, as its own guidance cites it) and may ask for additions, which suspends the terms. Article 2, paragraph 7 of Law 241/1990 separately allows a term to be suspended once, for no more than 30 days, to obtain information the administration does not already hold. One well-timed request can move a whole calendar by a month.

Day 40 is the first date an allocator can check against a document. The transmission to the Soprintendenza leaves a protocol number and a date, and the applicant is informed of it. If the file shows a transmission at day 38, the comune performed to the statute. If it shows day 140, that difference is information about the comune, about the file, or about both. Asking for the date costs nothing, and the answer costs the counterparty nothing if the file is clean.

Day 40 to day 85: the Soprintendenza#

From the day the Soprintendenza receives the file, it has 45 days to issue its opinion. Article 146, paragraphs 5 and 8 set the term at forty-five days from receipt of the documents. For Lake Como the body is the territorial Soprintendenza of the Ministry of Culture for the province of Como (SABAP CO-LC). Its clock starts on receipt, not on the application date, so any gap between day 0 and the transmission is added to the calendar without appearing in the Soprintendenza's own count.

The opinion is binding, which is why this step decides the calendar. Soprintendenza guidance states that the opinion is binding as long as the municipal planning has not been adapted to the landscape plan. Whether and when each lake comune has aligned its Piano di Governo del Territorio with the regional plan is therefore a variable in the calendar. We could not verify it comune by comune, and we say so in the disclosed weaknesses below.

A negative view arrives first as a notice, not as a refusal. Where the opinion would be negative, the Soprintendenza sends the notice under Article 10-bis of Law 241/1990. The applicant has ten days to submit written observations, and the terms are suspended in the meantime. This is the point at which designs change. A scheme revised after a 10-bis notice is a scheme whose clock has partly restarted, and the file will show it as a second dated exchange.

The Soprintendenza can also stop the clock at the door. It verifies completeness and can request additions, which suspends the procedure. In the ordinary track, then, day 40 is not a promise that day 85 follows. It is the earliest date on which the 45-day count can begin, and it is the count that is easiest to interrupt. The theoretical calendar assumes a file that was complete on first submission. That is an assumption, not a base rate.

Day 85 to day 105, and what silence does#

The comune has 20 days from receipt of the opinion to decide. Article 146, paragraph 8 sets the term. With a positive opinion the authorisation follows, and Soprintendenza guidance states it is effective immediately. On the arithmetic, the ordinary track closes at day 105 (40, then 45, then 20). That is the first of the two numbers this paper carries forward.

The statute also writes the failure case. Under paragraph 9, if 60 days pass from the Soprintendenza's receipt of the documents without an opinion, the comune decides on the application anyway. On the calendar above that is day 100. The market calls this silence-assent, and the label overstates it. What the statute allows is that the comune may proceed. It does not say that the authorisation is granted.

The Consiglio di Stato has narrowed the label further. In judgment no. 2640 of 29 March 2021, as reported by a law-firm commentary, it held that the silence-assent rule of Article 17-bis of Law 241/1990 does not apply to the instruction phase of the Article 146 procedure. The comune must still carry out the full investigation and prepare the proposal. Silence does not remove the work. It changes who may decide when the co-deciding body does not speak.

Late opinions are a live legal question, and we do not resolve it. A first-instance judgment, TAR Campania no. 4406/2025, on the related Article 167 compatibility procedure, is reported to have held that an opinion issued far beyond its 90-day term lost its binding force. That is one ruling, on a different procedure, reported through a trade publication. Treat it as directional. It does not show that a lakefront comune will proceed without the opinion, and no principal should underwrite a schedule on the assumption that it will.

The clock-stoppers#

The theoretical calendar is a ceiling only if nothing stops the clock, and the law lists what can. Three mechanisms recur. A one-time suspension of up to 30 days to acquire information, under Article 2, paragraph 7 of Law 241/1990. The 10-bis notice, which gives the applicant ten days for observations and suspends the term. And, in the building permit, a one-time interruption within 30 days of filing under Article 20, paragraph 5 of DPR 380/2001.

Stacked, they move the calendar in blocks of weeks. Take the ordinary landscape track. Add one 30-day suspension for additions and one ten-day 10-bis exchange, and 105 days becomes 145 before any redesign time is counted. That figure is Victaura arithmetic on the statutory ceilings. It is an illustration of how the terms compound, not an observation of any file.

The asymmetry that matters is who holds the pen. Statutory terms bind the administration. The time an applicant needs to answer a request is the applicant's own, and on a heritage villa the answer may need archival research, structural checks and a fresh survey. The clock the law stops is the administration's. The clock that keeps running is the carrying cost of the asset, and it is borne by the principal.

A calendar with no stop in it is either an exceptional file or an incomplete one. An allocator reviewing a dated calendar should expect to see at least one suspension or exchange. A file that shows none deserves a question. It may reflect a complete first submission and a responsive comune. It may equally reflect a calendar that has been tidied for presentation. The dated protocol records, not the summary, settle which.

The short track and its limits#

DPR 31/2017 replaces 105 days with 60, but only for a closed list of small interventions. Article 11 sets a peremptory 60-day term from receipt of the application. The individual terms are short. The administration has ten days for its initial verification and a single request for documents, and the applicant has ten days to answer. The comune then has 20 days to send a reasoned proposal, the Soprintendenza has 20 days for its binding opinion and the comune has ten days to decide.

A substantial lakefront restoration will usually not qualify. As set out in the companion paper, material changes to openings, roofline or external finishes fall in the ordinary track. The simplified list is for small-scale changes to existing buildings. Which track applies is the first decision in the calendar, and Article 11 gives it to the administration on receipt. An applicant who plans on 60 days and is moved to the ordinary track has lost 45 days before day 10.

In the simplified track the local commission is optional unless regional law says otherwise. Article 11 provides that the opinion of the local landscape commissions is not mandatory in the simplified procedure, save for what regional laws provide. We did not verify the Lombardy position or how each lake comune applies it. That is a further calendar variable, and it is one that an applicant's counsel can settle in an afternoon.

The short track has a longer tail on the negative path. If the administration's evaluation is negative it says so within ten days and the applicant has 15 days to submit observations or a revised project. If the Soprintendenza denies the proposal, the applicant again has 15 days before a final decision period of 20 days. The headline 60 days is the term for a clean, positive file. It is not the term for a contested one.

After the authorisation: the building permit and the expiry clock#

The landscape authorisation is not the end of the calendar. It is the entry ticket to the second one. The authorisation is a separate act, and the building title on a protected site cannot be issued without it. The permesso di costruire then runs its own terms under Article 20 of DPR 380/2001. The responsible officer has 60 days from filing to complete the instruction and formulate a proposal, acquiring the other assents required under Article 14 and following of Law 241/1990.

The permit's decision term is 30 days, or 40 after a 10-bis notice. Paragraph 6 gives the dirigente 30 days from the proposal to adopt the final act. Paragraph 5 allows one interruption of the instruction term, within 30 days of filing, to request further documents. Paragraph 7 doubles the terms of paragraphs 3 and 5 for particularly complex projects, which moves the instruction term from 60 to 120 days. A restoration on a protected lakefront is a plausible candidate for that label, but whether a given comune applies it is a matter for the file.

Silence does not build the permit on a constrained site. Article 20 introduced silence-assent for ordinary permits, but for properties subject to landscape, heritage, environmental or hydrogeological constraints the procedure ends with an express measure. A lakefront villa inside the 300-metre band is constrained by law. The calendar therefore ends on an act, not on a date, and the paper trail is the only evidence that it has ended.

The arithmetic gives a ceiling of about 195 days before any stop, and 255 if the instruction term is doubled. That is 105 days for the authorisation plus 90 for the permit, or 105 plus 120 plus 30. The permit instruction may overlap the landscape procedure in part, since the officer acquires other assents, but the statute does not let us size that overlap. Both figures are Victaura arithmetic.

The authorisation also carries its own expiry clock. It is effective for five years under Article 146, paragraph 4. Soprintendenza guidance adds that where works start within the five years they may be completed within one year of expiry. A process that consumes 24 months on the industry estimate leaves roughly three years to begin works. Delay in the permit phase is therefore not only carrying cost. It also shortens the window in which the authorisation can be used.

Theoretical versus actual#

The gap between the theoretical calendar and the real one is the most useful number in this market, and it is not published. We looked for a measured series of landscape authorisation durations by Soprintendenza or by lake comune and did not find one. The World Bank's Doing Business series measured construction permitting, but it modelled a warehouse, not a protected villa, and it does not isolate the landscape step. Nothing we found measures what this paper needs.

What exists is practitioner experience. The companion paper places a substantial restoration of a protected lakefront villa at 12 to 24 months from application to executive title. That is an industry estimate, not an audited series. Against a 195-day ceiling it implies a multiple of roughly 1.9 to 3.7, which is Victaura arithmetic on an unaudited range. The width of the range is itself the honest finding.

The sources of the gap are structural, but their weights are unknown. Suspensions, 10-bis exchanges, commission meeting calendars, redesign after observations and the sequencing of the permit all sit between the statutory terms and the elapsed time. Some part of the 12 to 24 months may also fall before day 0, in design and informal dialogue, and no statutory count includes it. We cannot say how much. Anyone who quotes a single split is guessing.

The useful measure is therefore per file, not per market. A market average would hide the variation that matters, which is between comuni, between design languages and between counterparties. A principal can obtain a dated file from a specific operator on a specific parcel. That file is a sample of one, but it is a sample of one that is real and third-party stamped, and it is what a market series would have been built from.

Weak points, honestly disclosed#

The terms were read from consolidated reproductions and official guidance, not from the consolidated text on Normattiva. The statutory numbers come from a legal-database reproduction of Article 146 and Article 20 of DPR 380/2001, from the text of DPR 31/2017 and from Soprintendenza guidance pages. Secondary sources disagreed in one place. One trade summary gives 25 days for the Soprintendenza in the simplified track, while the decree text reproduced above gives 20. We used 20. Counsel should confirm every term against the current text.

Expiry of a term does not mean what the calendar implies. A term binds the administration, but the consequence of a missed term differs by step and is contested in case law. We did not survey the case law, and we cite two rulings only as directional. The 60-day rule in paragraph 9 lets the comune proceed. Whether an opinion arriving after 45 days is still binding is a question for lawyers, not for this table.

Comune-level variables are unverified. Whether each lake comune has aligned its planning with the regional plan, how often each commission meets, how each applies the complexity doubling and whether the commission opinion is required in the simplified track were not checked comune by comune. Each can move the calendar by weeks. The paper describes the frame, and the frame does not replace a per-comune review.

Other bodies are not modelled. Hydraulic and hydrogeological review, seismic filing, any lake-domain concession for a boathouse or jetty, and appeals to the administrative court each run their own clocks. Third-party challenges are excluded as well. The calendar covers the two central procedures only, and a real programme adds to it.

Nothing here is a statement about Victaura's own files. We do not publish internal durations, and the figures above describe the statute and reported industry experience. The law as read here is the law as we understood it in September 2026, and the terms in this area are amended often.

What the allocator should ask for#

Ask for the dated file, and ask for it in the order of the calendar. The list is short. The application protocol date. The date of transmission to the Soprintendenza. The date and content of any request for additions. The date of the opinion. Any 10-bis notice and the reply. The authorisation date. The permit filing date and the date of the final act. Each is a stamped record, and none of them requires the operator to disclose anything commercial.

Then compute three ratios from it. The first is elapsed days against statutory days at each step. The second is the number of stops. The third is the share of elapsed time that sits with the administration against the share that sits with the applicant. If delay clusters in the administration's steps, the risk is at comune level. If it clusters in the applicant's answers, the risk is in design and preparation. The two call for different judgements about the counterparty.

Price the gap, not the ceiling. The statutory 105 and 195 days are the fastest lawful path, and they are a poor input for a financing plan. A holding period that is underwritten on the observed calendar of a comparable file is defensible. One underwritten on the statute is a hope. The carrying cost of the asset runs through every day the file waits, whichever party is responsible for the wait.

A calendar does not say whether a scheme will be approved. Approval is a design question, and the calendar is a time question. A clean calendar on a modest scheme says little about a larger one. What the calendar does show is whether the operator files complete applications, answers requests promptly and knows the comune it is working in. Those are observable behaviours, and they are worth more than any description of relationships.
