Licensed Granny Flat Builders in Campbelltown — CDC, 60m², from $130K

A standard 60m² two-bedroom turnkey granny flat in Campbelltown costs $130,000–$200,000 in 2026 under SEPP (Housing) 2021 Complying Development. Custom-designed builds run $180,000–$280,000. The Campbelltown Local Infrastructure Contributions Plan (Amendment 1) 2018 charges a flat S7.11 rate — $14,177 at June 2024 CPI (quarterly-indexed, est. ~$15,200–$15,800* at May 2026). This flat rate applies whether your build costs $150,000 or $280,000 — unlike Camden’s percentage-based S7.12, it doesn’t shrink with a lower build cost. Bushfire BAL premiums apply for Eagle Vale, Glen Alpine, Kentlyn and Appin fringe lots (+$3,000–$30,000*). Flood-affected lots near Bow Bowing Creek or Leumeah Creek add elevated floor costs (+$10,000–$25,000*). Add BASIX, Sydney Water Section 73 and HBCF insurance.

The minimum lot size is 450m² under SEPP (Housing) 2021 for the CDC pathway. Campbelltown’s lot profile varies significantly. Established western suburbs (Blair Athol, Bradbury, Woodbine, Englorie Park, Ambarvale, Ruse, St Helens Park, Leumeah) typically have lots of 550m²–800m² — generally CDC-eligible where DCP 2015 Section 7.3 controls are met. Urban renewal precincts (Airds, Claymore, Blairmount) have many lots of 350m²–500m², CDC-blocked. Menangle Park growth estate lots commonly 350m²–550m² — often below SEPP threshold, requiring DA. Rural-residential lots in Appin, Kentlyn and Wedderburn typically 1,000m²+ — CDC-eligible in principle but subject to BAL assessment.

The Campbelltown Local Infrastructure Contributions Plan (Amendment 1) 2018 (effective 27 November 2023) charges a flat S7.11 rate of $14,177.34 for secondary dwellings at June 2024 CPI of 139.1 — quarterly-indexed (est. $15,200–$15,800* at May 2026). This flat-rate model means a $180,000 Campbelltown build pays the same S7.11 contribution as a $280,000 build. Secondary dwellings in Menangle Park are also charged at this flat rate under CLIPC 2018 Amendment 1 — NOT the Menangle Park Contributions Plan (confirmed in the 27 November 2023 amendment, saving $23,000–$40,000 over the Menangle Park CP rate). Confirm the current indexed rate with Campbelltown City Council at time of project lodgement.

Campbelltown (Sustainable City) DCP 2015 Section 7.3 Secondary Dwellings sets local controls above the SEPP baseline. Key requirements: (1) Secondary dwelling must be positioned behind the front building alignment of the principal dwelling — no street-fronting granny flats. (2) No internal fence separating the principal and secondary dwellings — must read as one property. (3) No subdivision (strata or Torrens title) — cannot be sold separately. (4) Site coverage of all structures must comply with R2 Low Density Residential zone standards under Campbelltown LEP 2015.* Minimum private open space per DCP Section 5.2. Properties in Airds, Claymore and Blairmount are additionally subject to the Urban Renewal Areas DCP (URADCP) under the 2012/2013 Concept Plan approvals. A Campbelltown-experienced builder should run every preliminary design against these controls before submitting for certification.

Yes — always. Pathway 1: Complying Development Certificate (CDC) — issued by a private certifier in 10–20 business days. Available where the lot meets SEPP (Housing) 2021 standards (450m²+, existing principal dwelling, no heritage overlay, BAL-29 or lower, not flood-affected, setbacks met) AND complies with Campbelltown DCP 2015 Section 7.3. Pathway 2: Development Application (DA) — lodged with Campbelltown City Council, assessed under DCP 2015 Section 7.3 and URADCP where applicable. Required where any CDC standard isn’t met: sub-450m² lot, heritage item overlay, BAL-40+, flood zone. Allow 10–18 weeks* for DA assessment at Campbelltown. Both pathways require BASIX, Sydney Water Section 73, and HBCF insurance before deposit is paid. The CLIPC 2018 Amendment 1 S7.11 flat rate (~$15,500*) applies on both pathways.

It depends on whether your property is itself heritage-listed or adjacent to a listed item. Campbelltown’s State Heritage Register items include the Queen Street Buildings Group (284–298 Queen Street, listed 2 April 1999) and the Warby Barn near the northern CBD. Glenalvon at Lithgow Street is locally heritage-listed. Over 120 individual items are in Campbelltown LEP 2015 Schedule 5. SEPP (Housing) 2021 excludes heritage-listed properties from the CDC pathway — requiring a DA through Campbelltown City Council. Development adjacent to a heritage item requires a Heritage Impact Statement under Campbelltown LEP 2015 Clause 5.10. Add $3,000–$10,000* for heritage design fees and 8–16 additional weeks for heritage advisor referral. Always confirm heritage status via a Section 10.7(2) certificate before commissioning any design work.

End-to-end timeline for a Campbelltown CDC granny flat is approximately 5–7 months: 2–4 weeks for design/BASIX/survey; 10–20 business days CDC via private certifier; then 12–16 weeks construction. For the DA pathway — sub-450m² lots in Airds, Claymore, Blairmount or Menangle Park; BAL-40+ fringe properties; flood-affected lots near Bow Bowing Creek or Leumeah Creek; or heritage-adjacent properties near Queen Street — add 10–18 weeks* for Campbelltown City Council DA assessment. Site-specific extensions: BPAD BAL assessment for Eagle Vale/Glen Alpine/Appin fringe (2–4 weeks); flood FPL survey for Bow Bowing Creek/Leumeah Creek lots (4–8 weeks); Heritage Impact Statement for Queen Street/Lithgow Street precinct (4–8 weeks); URADCP design review for Airds/Claymore urban renewal lots (4–6 weeks).

A Section 10.7(2) Planning Certificate from Campbelltown City Council costs $59–$159 and takes approximately 5 business days. It confirms: your Campbelltown LEP 2015 zone (R2, R3, R5, RU2 for rural lots); heritage item listing or HCA status (State Heritage Register items on Queen Street, Glenalvon at Lithgow Street, Schedule 5 local items); bushfire prone land classification (critical for Eagle Vale, Glen Alpine, Kentlyn, Appin fringe lots); flood classification (Bow Bowing Creek, Leumeah Creek, Georges River corridor, local overland flow); and the applicable contributions plan (CLIPC 2018 Amendment 1 for most of the LGA). Any builder quoting a Campbelltown granny flat without sighting a 10.7 certificate is working blind on BAL, flood and heritage — the three biggest site-cost risk factors in this LGA. The $59–$159 spend before commissioning design pays for itself on a $180,000+ project.

Yes — NSW law permits renting a secondary dwelling to any tenant, including non-family members, under a standard Residential Tenancy Act 2010 agreement. Typical 2-bedroom granny flat rents in Campbelltown 2560 are approximately $390–$480 per week*, varying with finish quality, parking and proximity to Campbelltown train station and Macarthur Square. A turnkey 60m² CDC build at $180,000 returning $430/week represents approximately 12.4% gross rental yield on construction cost before holding costs, vacancy and depreciation. SEPP (Housing) 2021 and Campbelltown DCP 2015 Section 7.3 both prohibit strata and Torrens title subdivision — the granny flat cannot be sold separately from the principal dwelling, and no internal fence between the dwellings is permitted. Separate utility metering is strongly recommended for tenant cost allocation.
