What is the modern rubrics of the Blessing of the House? Do Priests even do this anymore?
Today the emphasis in on blessing the familiy, rather than the house.
From the 2002 Directory on Popular Piety and the Liturgy at

“
Eastertide
*The Annual Blessing of Family Homes
*152. The annual blessing of families takes places in their homes during Eastertide - or at other times of the year. This pastoral practice is highly recommended to parish priests and to their assistant priests since it is greatly appreciated by the faithful and affords a precious occasion to recollect God’s constant presence among Christian families. It is also an opportunity to invite the faithful to live according to the Gospel, and to exhort parents and children to preserve and promote the mystery of being “a domestic church”.”
There is a footnote to this, which is in Latin, but which refers to the ceremony in: Book of Blessings, Liturgical Press, Minnesota, 1989, ISBN 0-8146-1875-8, page 13 “Order for the Annual Blessing of Families in Their Own Homes”, n. 68 - 89.
The ceremony is lead by a priest or deacon. The rubrics give considerable latitude regarding how it is to be celebrated:
“74 While maintaining the structure and chief elements of the rite, the celebrant should adapt the celebration to the circumstances of the place and the families involved.”
Here is the structure:
Community gathers
Greeting
Celebrant says introductory words, preparing people.
Reading, by one present or celebrant, (eg. Matthew 7:24-28).
Psalm or other song.
Intercessions, introduced by celebrant, intentions by another.
Prayer of Blessing (by celebrant, with hands outstreched).
Sprinkling of those present and the home with holy water. (Perhaps with a prayer said).
Concluding rite: prayer said by celebrant.
Preferably a song is sung to conclude the celebration.
Another blessing is “Order for the Blessing of a New Home”. A lay person can lead this. It also gives the minister scope to change the ceremony. The structure for this:
Family, relatives and friends gather.
Sign of the Cross
Greeting by minister
Minister says words of introduction
Reading, by minister or another person (eg: Luke 10:5-9)
Psalm or other song
Intercessions, introduced by minister, intentions by another.
Prayer of Blessing (If by lay minister, with hands joined. Otherwise hands outstreched).
Sprinkling of those present and the home with holy water. (Perhaps with a prayer said).
Concluding rite: prayer said by minister.
Preferably a song is sung to conclude the celebration.
(Book of Blessings, Liturgical Press, Minnesota, 1989, ISBN 0-8146-1875-8, pages 237-242, n. 660-677).
So very similar structures, but different prayers and different rules about lay ministers leading it.
