All residents: Rules for living in Parkrise Flats

We all want to live comfortably and safely here, so here are a few simple rules which we think all residents should follow.

Rubbish

Rubbish collection is on Tuesdays. Please do not leave rubbish bags out before Tuesday as birds and animals can break into them and they smell.

Washing

There is a washing line for every flat in the garden next to the car park. Please only dry your washing on these lines so it does not disturb（干扰）people in the ground floor flats.

Cleaning

The main stairs are cleaned twice a week by the Association, so please try to keep them tidy and clean and do not leave furniture or bags on the stairs or in the hallways.

Lights

The main lights are on a timer and they stay on for five minutes whey you press them. Please tell the Association if any lights are not working.

Noise

Residents are asked to keep noise to a minimum. Loud music, etc. can disturb other people and the Association will get in touch with you if you make too much noise.

Safety

Make sure the main outside door is always locked and do not let anyone in to the main building unless you know who they are. Sometimes people try to get in to the main stairs and then break into flats, so do not let people in unless they are coming to see you.

Parking

Each flat has one car parking space. These are numbered and are at the back of the building. Do not use another resident's space. If you have more than one car you will have to park it on the road. Do not park where you are blocking entrances.

Problems

If you have any problems or questions, please call the Association at 0800 096 9000.
