In short and in plain language
When it is icy, people spread something on sidewalks. This can be salt or grit. Each town decides which one is allowed.
In Hildesheim, Hanover and Brunswick, sidewalks get grit or sand. Salt is only allowed in special cases there. In Hanover and Brunswick, for example, on steps.
Salt harms trees and hedges. It stays in the soil for a long time. You often see the damage only later, for example in summer.
In spring, the grit has to be swept up again. A garden firm can offer this as a separate job.
We build websites on which garden firms explain this well.
When the first frost settles on the sidewalks in November, winter service firms hear the same question as every year: will you use salt or grit? The honest answer is that neither the firm nor the client decides. The town does. There is no uniform rule at federal or state level (Umweltbundesamt). Even between Hildesheim, Hanover and Brunswick, the permitted gritting material, the width to be cleared and the date by which the grit has to come off the sidewalk in spring all differ. This article shows where these rules are set, what they mean for sidewalks, steps and driveways, and why a landscaping firm has more to offer on road salt than a pure snow clearing service: it knows the hedge along the sidewalk and the tree by the driveway, where salt damage often shows only months later. At the end, it shows how the winter service page explains all of this without giving legal advice and without a blanket statement that is no longer true in the next town.
Key takeaways
- There is no uniform rule on road salt at federal or state level (Umweltbundesamt). In Lower Saxony, a town can pass winter service to adjacent owners by bylaw, and its ordinance sets the gritting material.
- Hildesheim allows salt on sidewalks only in exceptional weather such as freezing rain, Hanover on steps and ramps, Brunswick on sidewalk steps and ramps. The service page states the rule for each town.
- Public sidewalks get grit or sand, salt at most on steps and only where local law permits it. In Hanover, the tree protection bylaw explicitly names road salt as harm to protected trees, private land included.
- Salt builds up in the soil over many years, and damage to trees and hedges often appears only with a delay, for example as brown leaf edges in early summer (Umweltbundesamt). Spreading without salt protects woody plants.
- Sweeping up grit is a spring service of its own: in Brunswick it must come off by 21 March at the latest (Straßenreinigungsverordnung Braunschweig), in Hanover it may stay until 31 March as long as it poses no slipping risk.
- The winter service page lists the gritting material per surface and per town, along with the version of the rules it was checked against, and refers to local law instead of promising salt-free or salt across the board.
No nationwide rule: local law decides
The German Environment Agency sums up the legal situation plainly: in many municipalities, private use of road salt is explicitly prohibited and subject to a fine, exceptions mostly cover steps and other critical areas, and there is no uniform regulation at federal or state level (Umweltbundesamt). For a winter service firm, this means every town in the service area is a case of its own. Clearing in five towns means working under five sets of rules, and a statement that is correct in the county town can be wrong two town signs further on.
In Lower Saxony, the basis is the state roads act. Streets within built-up areas must be cleaned, and cleaning explicitly includes clearing snow from roads and sidewalks and, in icy conditions, gritting sidewalks, pedestrian crossings and dangerous stretches of road with more than insignificant traffic (Section 52(1) NStrG). The duty initially lies with the municipalities (Section 52(2) NStrG). They can pass it on in full or in part to the owners of adjacent properties by bylaw (Section 52(4) NStrG). The type, extent and spatial scope of cleaning, on the other hand, are set by the municipality in an ordinance (Section 52(1) NStrG).
This leads to a detail that many websites get mixed up: there are usually two documents. The street cleaning bylaw says who has to clear and grit. The street cleaning ordinance says how wide, at what times and with what. In Hildesheim, for example, the bylaw passes on to owners, among other things, the removal of snow and ice from sidewalks and refers explicitly to the ordinance for type, extent and spatial scope (Straßenreinigungssatzung Hildesheim, Section 2(1)). When a service page talks about the bylaw, it usually means local law in general. Anyone who wants to check which gritting material is allowed reads the ordinance.
For service providers, the roads act contains a sentence that belongs in contract preparation: if, with the municipality's consent, someone else has taken over carrying out the cleaning for the person responsible, only that party is obliged under public law, and the municipality's consent can be revoked at any time (Section 52(4) NStrG). Read the other way round, without this consent the public-law duty stays with the owner, even if a firm clears the snow under contract. How contracts, liability and service records fit together in winter service is covered in Offering winter maintenance: contracts, duties, records. This article deals with the question that appears there only as a field in the log: which gritting material is allowed where.
Read local law with a date
Three cities, three rules: Hildesheim, Hanover, Brunswick
In Hildesheim, sidewalks must be gritted with sand or other salt-free, abrasive materials in snow and ice. Road salt is only permitted in special weather exceptions such as freezing rain, where abrasive materials cannot provide enough grip (Straßenreinigungsverordnung Hildesheim, Section 5(8)). Sidewalks narrower than 1.50 m are cleared in full, wider ones over at least 1.50 m (Straßenreinigungsverordnung Hildesheim, Section 5(2)). Clearing applies on weekdays from 7 a.m. to 10 p.m. and on Sundays and public holidays from 8 a.m. to 10 p.m. (Straßenreinigungsverordnung Hildesheim, Section 5(5)). The Hildesheim ordinance has no exception for steps. Leftover gritting material must be removed once there is no longer a risk of ice (Straßenreinigungsverordnung Hildesheim, Section 5(9)), and violations can be fined up to 5,000 euros (Straßenreinigungsverordnung Hildesheim, Section 7).
In Hanover, according to the municipal waste management association, there is a general ban on salt (aha Region Hannover). Pedestrian areas are gritted with abrasive materials over the same width as they are cleared. On steps and ramps, thawing agents such as salt or brine are permitted (Straßenreinigungsverordnung Hannover, Section 5(3)). Sidewalks must be kept clear over at least 1.50 m (Straßenreinigungsverordnung Hannover, Section 5(4)), and cleared snow is piled at least 0.30 m away from the road or bike lane (Straßenreinigungsverordnung Hannover, Section 5(6)). The ordinance lists the use of thawing agents such as salt among its administrative offenses, with fines of up to 5,000 euros (Straßenreinigungsverordnung Hannover, Section 7). Only in persistently extreme weather can the mayor allow salt on sidewalks as well in individual cases (aha Region Hannover).
Brunswick puts it most clearly: only abrasive gritting materials such as grit or sand may be used on sidewalks. Coarse materials such as crushed stone, salt, salt and sand mixtures and chemical thawing agents are not allowed. On sidewalk steps and ramps, salt is permitted to the extent required, and the mayor can allow temporary exceptions in particularly dangerous situations (Straßenreinigungsverordnung Braunschweig, Section 5(2)). Sidewalks are cleared and gritted over at least 1.20 m (Straßenreinigungsverordnung Braunschweig, Section 5(1)). Once wintry conditions are no longer expected, the grit must be removed, by the start of spring on 21 March at the latest (Straßenreinigungsverordnung Braunschweig, Section 5(2)). Here, too, fines can reach 5,000 euros (Straßenreinigungsverordnung Braunschweig, Section 6).

|---|---|---|---|
| Gritting material on sidewalks | sand or other salt-free, abrasive materials | abrasive materials | only abrasive materials such as grit or sand |

Three neighboring cities, three answers to the question about steps, two different clearing widths and three rules for grit in spring. For the winter service page, this is not a detail but the core. Anyone who writes that salt is banned across the board is wrong about steps in Hanover. Anyone who writes that steps are of course salted is wrong in Hildesheim. And anyone with further towns in the service area, for example in the district of Hildesheim or the Hanover region, checks their local law one by one, because the core city's ordinance does not apply there. How we structure websites for landscaping firms in Hildesheim, Hanover and Brunswick by town is shown on the regional pages.
Gritting by surface: sidewalk, steps, driveway
On the service page, a simple order helps: do not sort by material, sort by surface. Clients think in surfaces. The property manager has the sidewalk in front of the building, the entrance steps and the yard with the parking spaces. The private client has the sidewalk, three steps to the front door and the driveway. A different rule applies to each of these surfaces, and for some, street cleaning law does not apply at all.
The public sidewalk in front of the property is the clear case. The town's ordinance applies here, and in all three example cities abrasive materials are the rule. The German Environment Agency recommends salt-free, abrasive materials such as sand, grit or granules, recognizable in stores by the Blue Angel label, and advises using energy-intensive materials such as expanded clay only sparingly (Umweltbundesamt). Clearing comes first anyway: removing snow promptly makes additional gritting unnecessary in most cases, according to the agency, because trodden snow quickly turns into ice (Umweltbundesamt).
Steps are the contentious case. Hanover allows thawing agents on steps and ramps, Brunswick allows salt on sidewalk steps and ramps, Hildesheim allows salt only in exceptional weather. Even where salt is allowed, restraint pays off. Steps often sit right next to planting beds, and the meltwater does not run where it harms nobody but into the bed beside the stair stringer. A firm that states on its page that it uses salt on steps only where local law allows it, and even then sparingly and away from beds, answers the question before it is asked.
Driveways, yards and parking spaces on private land are the third case. The street cleaning ordinances apply to public streets, paths and squares, and in Hanover explicitly also to areas that are in fact used by public traffic (Straßenreinigungsverordnung Hannover, Section 2(1)). A freely accessible customer parking lot can therefore fall under it, a closed-off driveway is less likely to. When in doubt, the city clarifies. Where street cleaning law does not apply, the question is still not settled: in Hanover, the tree protection bylaw prohibits impairing protected trees, shrubs and hedges and explicitly lists the use of road salts as an example of such impairment. For trees, the root zone is generally the ground area under the crown (Baumschutzsatzung Hannover, Section 3(2)).
In Hanover, protection covers, among others, all deciduous trees with a trunk circumference of at least 60 cm and all conifers from 80 cm, measured 100 cm above the ground (Baumschutzsatzung Hannover, Section 2(1)). The driveway under the old linden tree is therefore no place for salt, even on private land. Firms that look after gardens with older trees in Hanover say so on their page: under the crowns of protected trees, we spread abrasive materials only. Which other rules apply to work on trees is covered in Tree protection and felling seasons.
Sidewalk in front of the property
Gritting material according to the town's ordinance, grit or sand in the three example cities. State clearing width and times per town, salt only where the ordinance explicitly allows it.
Steps and ramps
Salt only where local law permits it: in Hanover and Brunswick on steps and ramps, in Hildesheim only in exceptional weather. Sparingly and away from planting beds.
Driveway, yard, parking
Abrasive materials as the rule. Freely accessible customer parking can fall under street cleaning law, and the root zones of protected trees under the tree protection bylaw.
What salt does to a garden
For a landscaping firm, the salt ban is not just public order law but its own field of expertise. The German Environment Agency describes the use of road salt as very harmful to trees and other plants, animals, waterways, vehicles and structures, especially concrete (Umweltbundesamt). If salt reaches plants directly with splashed snow or water, it causes contact damage. Even more important is the salt that seeps into the ground: it can accumulate in roadside soils over many years, so damage to vegetation often appears only with a delay (Umweltbundesamt).
Anyone who looks after hedges along sidewalks knows what happens next. With excessive salt in the soil, important nutrients are washed out, the fine roots of trees die off and the symbiosis with soil fungi suffers. In deciduous trees, the leaf edges turn pale in early summer, the discoloration spreads toward the middle of the leaf and turns brown, followed by leaf margin necrosis and premature leaf fall (Umweltbundesamt). The closer a plant stands to the path, the more severe the damage tends to be, and avenue species such as maple, linden and horse chestnut are considered sensitive to salt (Umweltbundesamt). The hedge on the property line and the house tree next to the driveway stand exactly there.
On top of that come damages that clients rarely connect with winter. Salts attack materials, concrete structures suffer from their corrosive effect on the reinforcement, and brick structures can decompose as well (Umweltbundesamt). For pets, walking for longer on salted ground can inflame the paws (Umweltbundesamt). And on streets in built-up areas, road salt flows with the meltwater into the sewer system and, after the treatment plant, into streams or rivers (Umweltbundesamt).
The scale explains why municipalities push back. The German Environment Agency gives an annual average of roughly 1.5 million metric tons of road salt on German roads and paths over ten years, and more than four million metric tons in harsh winters; it cites a 2004 life cycle assessment as the source of these figures (Umweltbundesamt, Öko-Institut 2004). The numbers are older than they sound, but they show the scale. Sodium chloride only works down to about minus 10 °C, calcium chloride down to minus 20 °C (Umweltbundesamt). Abrasive materials, by contrast, do not thaw anything; they make the surface less slippery. For clients, this is the most understandable explanation of why grit is not a stopgap but the material that most sidewalks in the three example cities must be gritted with.
- Clear before gritting: remove snow promptly so it does not get trodden down and less gritting material is needed.
- Grit sidewalks with grit or sand, use salt only on steps and ramps and only where the town's ordinance permits it.
- Do not push snow with salt residue onto beds, hedge bases or tree pits; pile it at the edge of the sidewalk, in Hanover at least 0.30 m from the road (Straßenreinigungsverordnung Hannover, Section 5(6)).
- Keep gutters and drains clear during thaws so that meltwater runs off instead of standing in planting areas.
- In early summer, check hedges and trees along sidewalks for pale and brown leaf edges, because salt damage often appears only with a delay.
Grit in spring: the add-on service in March
Grit has one drawback that salt does not: it stays where it is. After the last frost, it lies on sidewalks, in entrances, on the lawn next to the driveway and in the paving joints. The German Environment Agency recommends sweeping up the spread grit after the snow melts and reusing it the next time it snows (Umweltbundesamt). Local law in the three example cities turns this into a duty with a deadline, and that deadline also differs from town to town.
In Brunswick, grit must be removed once wintry weather is no longer expected, by the calendar start of spring on 21 March at the latest (Straßenreinigungsverordnung Braunschweig, Section 5(2)). In Hildesheim, leftover gritting material must be removed once there is no longer a risk of ice (Straßenreinigungsverordnung Hildesheim, Section 5(9)). In Hanover, abrasive materials may stay on the surfaces until the end of the winter service season on 31 March, as long as they pose no risk such as slipping (Straßenreinigungsverordnung Hannover, Section 5(3)). The official winter service season in Hanover runs from 1 November to 31 March (aha Region Hannover).
For the firm, this is a service with a clear time window that many clients need anyway: picking up grit, sweeping the sidewalk and entrance, getting grit out of lawn edges and bed borders before the first mowing catches it, and storing the clean share dry for the next season. On the winter service page, it appears as a separate item with the note that the date follows local law. In the seasonal contract, it is an option that can be combined with the first maintenance round of the year. How such contracts are structured is shown in Offering garden maintenance contracts.

Stock grit and sand and add surface type, steps and ramps as well as trees and hedges in the gritting area to the site list.
Winter: clear, grit, record
Clear before gritting, record the material used per surface in the service log and use salt only where the ordinance permits it.
March: sweep up the grit
Pick up the grit by the town's deadline, clean lawn edges and beds and store clean grit dry for the next season.

How the winter service page explains gritting
Your own winter service page is where all of this comes together. It does not answer the gritting question with one sentence but with a small overview: surface, material, local rule. A firm that works in Hildesheim, Hanover and Brunswick lists the three rules side by side and states which version of local law it checked them against. This does not come across as petty but as knowledgeable, and it answers a question property managers ask anyway: who carries the risk if there is salt on the sidewalk in front of the building that should not be there?
Two kinds of wording do not belong on the page. The first is the generic environmental claim. Toward consumers, a generic environmental claim is not allowed if the business cannot demonstrate a recognized excellent environmental performance behind it (UWG, Annex No. 4a). An environmental claim is generic if its specification is not given clearly and prominently in the same medium (Section 2(2) No. 1 UWG). A phrase like eco-friendly winter service without an explanation next to it is therefore risky, while a concrete sentence such as we grit sidewalks without salt, using grit or sand, is a verifiable statement. Which other claims are tricky on landscaping websites is covered in Advertising with prices and claims.
The second is the blanket legal statement: road salt is banned. It is not true for steps in Hanover and Brunswick, not true for freezing rain in Hildesheim, and in Hanover and Brunswick also not when the mayor allows salt by way of exception. A concrete statement per surface and town is better, as the following overview contrasts.
| Blanket wording | Concrete on the service page (examples based on the street cleaning ordinances) |
|---|---|
| We grit in an eco-friendly way. | We grit sidewalks without salt, using grit or sand. |
| Road salt is banned. | In Hildesheim, salt on sidewalks is only allowed in weather exceptions such as freezing rain; in Hanover and Brunswick it is allowed on steps and ramps. |
| Salt on request. | We use salt only where your town's ordinance allows it, and only after your approval. |
| We keep your paths clear. | We clear the width and at the times your town requires, and record every call-out in the service log. |
| Grit will be removed. | Spring sweep: we pick up the grit by your town's deadline, in Brunswick by 21 March at the latest. |
Because the rules change at the town boundary, the service area belongs on the page with the town names written out. One line per town is enough: material on sidewalks, salt on steps yes or no, spring deadline, version checked. This helps clients and search engines alike, because someone searching for winter service with a town name finds a page that really knows their town. How location details support visibility is covered on the page about local SEO for landscapers.
The enquiry form then asks not just for the address and surface but for the points that decide the gritting material: which town the property is in, whether steps or ramps are included, whether trees or hedges stand right next to the surfaces to be gritted and whether the spring sweep is wanted. That way, the applicable rule and what belongs in the quote are clear by the first callback.
Explain, do not advise
Records and contract: documenting the material
The gritting material is a field in the service log anyway. With local law in mind, it gains weight: for each surface, the log notes what was spread, and for salt additionally on which surface and on what basis, for example steps under the town's ordinance or sidewalk under a dated temporary approval. If the city asks or a neighbor complains about salt on the sidewalk, the answer is in the log. How a complete service record is structured is described in Offering winter maintenance.
In the contract, the gritting material belongs in the service description, not in the general terms: abrasive materials as the rule, salt only on named surfaces, only where local law allows it, and not at all on request. A firm that takes over the owner's duty with the municipality's consent is solely obliged under public law (Section 52(4) NStrG) and should name this role explicitly in the contract. Whether a specific clause holds up is a question for the individual case and belongs in a legal review before the season.
The salt topic thus turns into three contract components that go beyond pure snow clearing: salt-free winter service as the basic service, the spring sweep as an option and a short plant check in early summer for hedges and trees next to the gritted surfaces. The last one suits firms that offer tree care anyway and run their own tree care website. Firms that work in their clients' gardens in winter anyway combine the visits with fruit tree pruning in winter and show both services on the same website.
When the page gets updated
Local law changes more often than people think. The Hildesheim street cleaning bylaw was last amended on 26 January 2026 (Straßenreinigungssatzung Hildesheim). The Hanover street cleaning ordinance applies in the version of 1 January 2026 and replaced the version of 11 December 2023 (Straßenreinigungsverordnung Hannover). The Brunswick ordinance carries the ninth amending ordinance of 4 November 2025 (Straßenreinigungsverordnung Braunschweig). A winter service page that is written once and then forgotten will be wrong in one place after two winters, without anyone noticing.
That is why the check belongs in the annual plan: once in September, before winter service contracts are awarded, fetch the current version for each town and compare it with the page. The seasonal plan for the website is the right place for this, together with the other content that moves to the front in autumn. If a rule changes in the middle of winter, for example through a temporary salt approval by the mayor, a short, dated note goes on the page and comes off again as soon as the approval ends.
What the page cannot do: it replaces neither reading the ordinance nor legal advice in a dispute, and it does not make any winter predictable. But it prevents a client from signing with the wrong expectations, and it shows that the firm knows the difference between sidewalk, steps and root zone. For a landscaping firm, that is an advantage a pure snow clearing service would find hard to copy.
