How to Calculate San Diego Partial & Selective House Demolition Cost Step-by-Step

Step 1: Base Selective House Demo Rate & San Diego Haul Index

Start by selecting a preset or entering your exact demo zone in sq ft. Across San Diego County, surgical hand & mini-machine separation averages $7.4/sq ft (with a $3,400 minimum crew & equipment mobilization floor) adjusted by the 1.14x San Diego haul & transfer index.

Base Cost = Round(Max(Sq Ft × $7.4 × Access Multiplier, $3,400) × 1.14)

Step 2: Separation Complexity Multipliers

Single-Story Wing (1.0x): Applied based on site staging, structural complexity, and San Diego equipment access.
Occupied Home Cut (1.22x): Applied based on site staging, structural complexity, and San Diego equipment access.
2nd-Story Roof-Off (1.35x): Applied based on site staging, structural complexity, and San Diego equipment access.

Step 3: Shoring & Slab Saw-Cut

Engineered post/beam support & diamond-blade concrete cut. Select between Keep Framing Slab ($0), Temp Shoring Wall (+$2.95/sf), Shore + Slab Cut (+$5.25/sf) so your estimate reflects exact subsurface and finish-grade conditions.

Step 4: SDAPCD & Dust Barrier & Weatherproof & Tie-In

San Diego compliance and dust/site controls (negative-air zip barriers & CAC asbestos survey compliance) include options for SDAPCD + ZIP Wall (+$845), Abatement + HEPA (+$2,450), HEPA Dust Zip Only (+$350). Bundling adjacent work during the same mobilization (Clean Framing Cut ($0), Weather Tarp Seal (+$695), Stucco & Roof Cut (+$1,395), MEP Safe-Off Cap (+$2,150)) eliminates paying a second transport fee.

Step 5: DSD Remodel Demo Permit & Miramar C&D Diversion Credit

Permit and utility safety options include DSD Selective Permit (+$575), Permit Routing (+$375), Under GC Permit ($0). Source-separating clean concrete aggregate, metals, and green waste for Miramar Greenery & San Diego C&D recyclers (65%+ CALGreen diversion) earns an automatic -$250 to -$850 credit ($0.32/sq ft).

San Diego Partial & Selective House Demolition Cost FAQs

1. How much does partial & selective house demolition cost in San Diego in 2026?

In San Diego County, turnkey partial & selective house demolition averages $9,365 to $11,654 for a standard 750 sq ft scope (or roughly $10.82 to $17.34+ per sq ft, subject to a $3,400 minimum mobilization floor). Final pricing depends on separation complexity, shoring & slab saw-cut, and permit/testing selections.

2. What San Diego permits or environmental clearances apply to selective house demo?

Depending on jurisdiction and scope, projects coordinate through City of San Diego Development Services (DSD, 1222 First Ave), County PDS, or local city counters, alongside mandatory USA DigAlert 811 underground marking and SDAPCD & Dust Barrier (negative-air zip barriers & CAC asbestos survey compliance).

3. How long does active on-site work take once permits and utilities are cleared?

Once utility safe-offs and required notices are complete, active Class C-21 field execution for a typical 750 sq ft project in Mission Hills or Kensington generally finishes in 1 to 4 working days, including haul-off, magnetic nail/debris sweep, and finish grade check.

4. How do you protect adjacent structures, driveways, and neighbor lots in San Diego?

We lay heavy HDPE turf and curb protection mats, perform precision wet diamond relief saw-cutting before mechanical breaking, run continuous atomized water or HEPA dust suppression, and carry full commercial general liability and workers’ compensation coverage.

5. How does San Diego's 65%+ C&D recycling credit lower my total cost?

San Diego C&D ordinances and California CALGreen Title 24 require 65%+ material diversion. By source-separating clean concrete rubble, steel/rebar, and green waste for Miramar Greenery and certified San Diego recyclers, we avoid mixed-landfill penalties and pass a -$250 to -$850 credit directly onto your estimate.
