City objects to roof tiles after construction

Apart from that: "What is set - is set" or, in your case, "What lies - lies" As long as no one is endangered by deviations from the development plan, it is hardly possible for a building authority to enforce a subsequent change.

No. VG Augsburg, judgment of 15.11.2017 – Au 4 K 17.708. Here, a coverage change had to be made. Also here: OVG North Rhine-Westphalia, judgment of 09.02.2000 - 7 A 2386/98 However, this concerned extreme color differences. In the second judgment, the color palette is discussed extensively, so that I see no risk of official orders in the case of the OP.

Whether it is red or brown will be decided by the building authority if in doubt, not the manufacturer's designation and not your definition.

Yes, maybe.

but unfortunately not changeable.

Yes, by lawsuit.

It says light gray and red there. Red ranges from light red to brown. Light gray only means stone gray.

The question was what exactly is stated in the development plan, and that is certainly not stated like that in the development plan. Well, the risk of a lawsuit has to be weighed. Maybe he simply didn’t like the color himself so much that he gave in without resistance.

So we have now spoken with a neighbor whose pans are also red, but like ours, rather dark red, even brownish. He apparently also received exactly this letter back then and after mentioning the manufacturer's information, they were satisfied. Covering up and simply buying new ones would not be an option anyway. The development plan only specifies one color group; it even literally says "in shades of red." In our WINE RED, I would even risk a lawsuit.

What exactly does the office write? Are you being asked to do anything?

No. VG Augsburg, judgment of 15.11.2017 – Au 4 K 17.708. Here, a change of color was necessary. Likewise here: OVG Nordrhein-Westfalen, judgment of 09.02.2000 - 7 A 2386/98 However, this was about extreme color differences. The second judgment goes extensively into the color palette, so in the case of the OP I see no risk of official orders. Yes, maybe. Yes, through a lawsuit. The question was what exactly is stated in the development plan and that is certainly not stated like that in the development plan. Well, the litigation risk has to be weighed. Maybe he himself did not like the color that much, so he submitted without resistance.

bla bla bla.

bla bla bla.

If you have nothing to say, may I quote Dieter Nuhr:

I just wanted to show you your little mindset, my dear. Something that can never and under no circumstances be in a development plan.
