Septic permits in Tiny Township: who issues them, what to file
Before anything gets dug in Tiny Township, a sewage system permit has to exist — and the office that issues it, the forms it wants, and the local ground rules are all knowable in one read. Here is the whole picture.
Your permit office: the Township of Tiny Building Department. Tiny administers its own Part 8 program — new systems, replacements, repairs and lot suitability all go through the township office. One call before you start saves every wrong guess that follows.

The part nobody tells you
Designers charge $800–$2,000 just for the paperwork in these quotes.
Ontario law lets you do that part yourself, on your own property. OntarioSepticDesigner.ca turns your answers into the same 26-page package the township clerk sees every day — calculations, drawings, forms, all of it.
Who reviews your application
Tiny Township reviews its own sewage system applications through the Building Department — the same office that handles your building permit, which keeps new-build files under one roof. Waterfront properties along Georgian Bay may also need conservation-area input where regulated mapping applies. If anything here has changed since publication, the Authority Finder keeps the current answer by township.
What a complete application contains
1The provincial application form and schedules — the same Part 8 paperwork every Ontario office uses
2Design worksheets — daily flow, tank size, bed sizing from your T-time
3Soil evidence — test-hole logs; most offices want the holes left open
4A scaled site plan — every setback dimensioned, reserve area shown
5The cross-section — vertical clearances proven on paper
6The fee — per the current local schedule
The full piece-by-piece breakdown lives on the permit package page — it is literally the checklist reviewers use.
The local ground: what Tiny Township lots deal with
Tiny’s shoreline concessions sit on sandy soils that perc beautifully — but high seasonal water tables near the shore push many beds up into raised designs, and tight cottage lots make setback geometry the first thing to check. Inland farm lots are generally kinder. What systems cost here, and the local soil story in full, is on our Tiny Township septic page.
The $18,950 line that never appears on a quote
A real worked example: 3-bedroom bungalow, conventional bed. Tank supplied and set, pipe, stone, fabric, one day of machine and labour, permit allowance — $13,049 with HST. The same job quoted at $32,000. The gap is design fees, markup, and labour you may not need to buy.
Two minutes on the free checker shows the numbers your own lot generates — daily flow, tank size, risk level — before anyone quotes you.
