Because you're only using inner joins, just let the sql engine determine at which step in the process it will handle your where clause.

(It will take indexes and statistics into account for that to determine its sqlplan )

select distinct

a.accountno

, a.parcelno

, p.privateflag

, p.name1

, p.name2

, a.businessname

, ad.address1

, ad.address2

, ad.city

, ad.statecode

, ad.zipcode

, ad.province

, ad.country

, ad.postalcode

from tbladdress ad

inner join tblperson p

on p.personcode = ad.personcode

inner join tblacctowneraddress o

on o.addresscode = ad.addresscode

and o.personcode = p.personcode

inner join tblacct a

on a.accountno = o.accountno

where a.acctstatuscode = 'A'

and a.accountno not like 'P%'

and p.privateflag != '1'

and o.primaryownerflag = '1'

and a.verend = '99999999999'

and p.verend = '99999999999'

and o.verend = '99999999999'

and ad.verend = '99999999999'

order by a.accountno ;
