KlasG4e,
I'm glad you asked.
Firstly, it's not up to the layman. It's not one of those we get to each have a "position" on. The priest is the one responsible for the Blessed Sacrament, so he (actually, his Bishop might have the final say) gets to decide which chapels are worthy to have the Blessed Sacrament reserved.
We don't have the privilege of reserving the Blessed Sacrament at our chapel. We wish!
1. The chapel needs to have enough activity/parishioners. We don't even get weekly Mass at the moment.
2. The chapel needs to be secure (locked, alarm system, etc.) I think the expression is, "The Blessed Sacrament must be behind 3 locks" including the chapel building and the tabernacle itself, which functions like a safe. Our tabernacle's lock mechanism is actually broken.
3. The chapel in question must be 100% dedicated to sacred use. Our chapel has a few shelving units for family storage (hidden behind tarps and wooden walls), and part of these shelving units are used as walls to enclose the Sacristy, confessional, etc. In other words, even if we moved 100% of our stuff out of the chapel, we wouldn't gain much, and we'd actually have to replace many walls, tables, and shelving that the chapel is currently using!
Thus we have donated over 95% of the 1200 square foot building to exclusive chapel use. But that isn't 100%.
3. We have a tabernacle as you can see in the picture, but that was only used once for Holy Week services (including Adoration on Holy Thursday) and several times to reserve the Blessed Sacrament between the Consecration and Benediction right after Mass.
I hope this answers your questions.
We started this chapel (in this location, albeit with much less equipment) back in February 2013. We've been at it ever since. We hope that eventually we'll have the parishioners and the priests in the Resistance so that we can have weekly Mass again, and someday build up to the point where we can have the Blessed Sacrament reserved. Even if that means moving to a new building someday.
