Zevachim 113A

ומתן סביב, ותנופה, והגשה. רבי יהודה אומר: אין מנחה בבמה, וכיהון, ובגדי שרת, וכלי שרת, וריח ניחוח, ומחיצה לדמים, וריחוץ ידים ורגלים.

no placement of blood around all sides of the altar in offerings for which this is required, no waving of meal offerings, and no bringing of meal offerings to the corner of the altar prior to removal of the handful. R' Yehuda says: There is no meal offering sacrificed on an altar outside the Temple. And requiring a member of the priesthood to perform the sacrificial rites, the priestly service vestments, the service vessels, the pleasing aroma to God, the partition for the blood, i.e., the red line dividing the upper and lower halves of the altar, and the priest’s washing of hands and feet before his service all do not apply to sacrifice on private altars, as the service there need not be performed by priests nor follow all the protocols of the Temple service.

אבל הזמן, הנותר והטמא ⁠– שוין בזה ובזה.

But the intent to sacrifice or partake of the offering beyond its designated time, which renders the offering piggul; the halakha of portions of the offering left over [notar] beyond the time it may be eaten; and the prohibition against eating consecrated meat while ritually impure are equal in this, a private altar, and that, a public altar.

גמ׳ מאי חוץ מגתה? אמר ריש לקיש: חוץ ממקום הבדוק לה. אמר לו רבי יוחנן: והלא כל ארץ ישראל בדוקה היא!

Talmud: The Mishnah teaches that one who burns the red heifer outside its pit is not liable for sacrificing outside the Temple courtyard. The Talmud clarifies: What is the meaning of: Outside its pit? Reish Lakish said: It means outside the place that was inspected to ensure that it is not a gravesite, which would render it impure. R' Yoḥanan said to him: But is not all of Eretz Yisrael inspected for impurity? Therefore, there is no need for the site of the burning of the red heifer to be specially inspected.
