IWAKUNI MARINE CORPS AIR STATION, Japan — No trampolines in the parking lots. Only charcoal grills with electric starters on mid-rise balconies. No waterbeds unless you can prove you’ve got insurance to cover damage they might do. No drugs or gangs, period.

Most of those always have been the regulations in Iwakuni housing — but now they’re also orders.

A new station order spelling out base housing regulations, in part replacing the old housing manual, was created here in late July. Base Order 11101.3N, or the Base Housing Order, is the first command-issued order pertaining to housing at Iwakuni MCAS.

It is designed to clarify some of the rules — many of which already were in place via the old housing manual — for living in the base’s 718 housing units, Base Housing Manager Sally Gilmour said Thursday.

In a recent base news report, Sue Kear, Iwakuni housing director, explained that the handbook and station order “will set the standard for base housing. We hope this will define everything more thoroughly and fully explain eligibility requirements.”

A station order, signed and issued by base commander Col. David Darrah, can apply to the entire community. It’s akin to an ordinance in a city or town.

“A lot of what it says in the station order was in the old manual. Now there’s just more information,” Gilmour said. “Having a station order gives it a lot more weight.”

No significant number of problems or incidents prompted the new housing order, she said. “It was just time to clarify the instructions. We don’t have a lot of problems and we’re fortunate. Knock on wood, but we are a small base and we know all our residents.”

One change is that new arrivals in Iwakuni, who before had to take whatever housing they were assigned, now can apply for either a townhouse or a tower apartment. The base doesn’t guarantee they’ll get what they request but will attempt to accommodate them if possible, housing officials said.

Other regulations in the new order include:

• Waterbeds are not allowed unless residents prove they’re insured against possible damages.• Those asking to change housing must pass a housekeeping inspection announced at least 72 hours in advance.• A servicemember, civilian employee, family member or guest may not be involved with gangs or gang-related activities, use or sell illegal drugs or be involved in violent behavior or a disturbance involving a weapon.• Individual or group garage or yard sales are limited to two two-day sales per year.

Other occupancy rules in the new order and handbook include:

• No decorations are allowed on second-floor roof porch overhangs, service porch roofs or second floor ledges of townhouses.• The Base Housing Office must be notified in writing if a unit is to be vacant seven days or more. E-mail will suffice if pertinent details about the absence and the resident’s temporary location, including a phone number, are provided.• Housing officials will consider health-related requests to install hot tubs or spas. The base’s senior medical officer must verify the request. The resident pays all costs.

No portable basketball goals or trampolines are allowed in streets or housing-area parking lots.

• Only charcoal grills with electric starters are allowed on mid-rise balconies; lighter fluid and self-lighting charcoal are prohibited.• Small satellite dishes may be installed after a request is submitted in writing. The installations must not damage buildings.• Almost all rooftops, and covered and uncovered drainage ditches, are off limits.

The air station plans to schedule housing-related “mini-town hall meetings” to go explain all the regulations in the new station order and handbook, base housing officials said.
