The compliance framework

South African construction is governed by three interlocking regulatory bodies. GridLineProp's 35 years of practical experience with all three has been encoded into the biz/property/za skill domain.

SANS 10400

The technical code. Defines how structures must be designed and built. 23 parts from foundations to energy.

PlansStructuralFireEnergy

CIDB

The contractor registry. Defines who is eligible to build. Grades 1–9 with tender value limits.

GradingTendersProcurement

NHBRC

Consumer protection. Defines what warranties and inspections apply to residential construction.

Skills contributed

GridLineProp's domain expertise powers four production skills in the biz/property/za tree. Each skill encodes decades of real project experience into structured, reusable intelligence.

SANS 10400 — National Building Regulations

Production

All 23 parts of the SA building code. Plan submission requirements, occupancy classifications (A1–J4), competent person requirements, energy compliance routes, and deemed-to-satisfy vs rational design guidance.

Production

Grades 1–9 with tender value limits, 10 classes of works (CE, GB, ME, etc.), registration and upgrade process, financial sponsorship rules, procurement via the Standard for Uniformity, and the BUILD programme.

Expertise × skills map

How GridLineProp's real-world experience maps to each skill's content:

Plan submission

35 years of plans approved by City of Cape Town and City of Johannesburg municipalities. Grant's BSc Building (UCT) qualifies as a "competent person" under SANS 10400 Part A.

Energy (XA)

OFF-GRIDz advisory division — solar, energy-efficient envelope design, and reduced municipal dependency built into every home as standard, not as an afterthought.

Water systems

Greywater recycling, borehole, and rainwater harvesting systems designed into builds. Maps to SANS 10400 Parts P (drainage) and R (stormwater).

Contractors

29 years of vetting, grading, and developing contractors. Known for staff and subcontractor development — the CIDB BUILD programme philosophy in practice.

Inspections

Every GridLineProp home enrolled and inspected at all four NHBRC stages. Luxury clusters across two provinces — each unit signed off at foundation, wall plate, roof, and practical completion.

Two markets

Cape Town and Johannesburg have different municipalities, inspectors, and timelines. The skills capture both perspectives from lived experience.

NHBRC inspection track record

Every GridLineProp unit passes all four NHBRC stages. This experience directly shapes the inspection guidance in the skills.
