The short answer is that there is 
probably, a small preference. 
The gemara (Berachot 6a) 
says: “A person’s prayer is heard only in a beit knesset, as it says: 
‘… to hear the praise and the prayer’ (Melachim I, 8:28) – at the place of the 
praise, there should be the prayer.” The Rambam (Tefilla 8:1) cites this idea 
with the addition that the prayers will not be “heard at all times” outside of 
a beit knesset. This would seem to be an important reason to daven 
specifically in a shul, and indeed the Shulchan Aruch (Orach 
Chayim 90:9) writes: “A person should try to daven in a beit 
knesset with the community.” He continues that there is also a preference 
to daven in a beit knesset even if he will be davening 
there alone (this is the subject of a machloket Rishonim - see 
Beit Yosef, OC 90). 
The question is whether all 
davening out of a beit knesset is inferior and to what extent. 
The Magen Avraham (90:15) cites, as the reason for the Shulchan Aruch’s 
recommendation, the idea of b’rov am hadrat melech (roughly, it is 
preferable to the King when there is a large group). The Pri Megadim (ad loc.) 
posits that even without the factor of b’rov am, a shul is 
always a preference, as he assumes that the preferences of a minyan and 
a shul are both called for. This is not a clear conclusion. The 
Tzelach (Berachot 6a) says that the important thing is having one’s tefilla 
heard and that this can be accomplished either by davening 
in a shul, even as an individual, or by davening 
with a minyan, even out of shul.
There is another Talmudic source 
about davening in a beit knesset. The gemara 
(Berachot 8a) says that whoever does not daven in a community’s 
shul is called a bad neighbor and is slated for exile. The 
Chida (Machazik Beracha 90:4) says that this does not apply if the person 
davens elsewhere with a minyan because the Divine Presence 
dwells wherever a minyan is praying. However, he continues to 
say that in order to receive the full positive impact, it must be in a place 
that is “set for holiness.” The definition of “set for holiness” is not always 
clear. Public vs. private ownership is not the issue (see Rama 153:7). Whether 
steps were taken to allow occasional use of the place for meals, especially when 
limited to mitzva-related eating (see complex issue in Shulchan Aruch, 
OC 151:11; Igrot Moshe OC I:45) is also probably not critical. However, using 
one’s living room for a minyan after a regular shiur or a 
daily Mincha minyan in a business’s board room does not turn these 
places into batei knesset. 
While we accepted the 
preference of davening in a beit knesset (see Mishna 
Berura 90:38; Ishei Yisrael 8:2), this is not an absolute requirement. This 
qualification is important, not only to justify one opting out due to a 
significant inconvenience, but also because other preferences can potentially 
outweigh that of davening in shul. We will mention some such 
possible cases, while warning that the particulars of a given case can make all 
the difference. 1. Davening in a place where one learns on a regular 
basis (Shulchan Aruch, OC 90:18). 2. The speed of the davening and/or 
congregants’ behavior make one’s davening noticeably “better” out of 
the beit knesset (Ishei Yisrael 8:10; see Mishna Berura 90:28; Aruch 
Hashulchan, OC 90:15). 3. One will have to daven in the shul 
without a minyan, but can make one elsewhere (Mishna Berura 
ibid.).
We are generally strong believers in 
the importance of community on various grounds. We note that Rav Kook, 
commenting on Berachot 6a, says that it is important to show that one connects 
his prayer to the matter of publicizing Hashem’s greatness and that this is done 
most profoundly in the communal setting (Ein Ayah, Berachot 1: 48,49). That 
being said, sometimes even the most communally oriented people have recourse to 
davening outside a shul.
