Based on Mobile's local building codes, you'll need a permit when:
New masonry fireplace construction always requires a building permit. The work must comply with IRC Chapter 10 (Chimneys and Fireplaces) including foundation, firebox, hearth, and chimney requirements. Chimney termination must follow the 2-10-3 rule (IRC R1003.9): 3 feet above the roof penetration, 2 feet above any building portion within 10 feet horizontally.

Gas fireplace insert installation requires both a mechanical permit (for the appliance) and a gas permit (for the gas line connection). Gas line work requires a licensed gas fitter or plumber and a pressure test per IFGC Section 406. Direct-vent models are safer (sealed combustion from outside) than B-vent atmospheric models.

Chimney rebuild or major repair requires a building permit. The work must comply with IRC Chapter 10 including flue liner requirements, termination height (2-10-3 rule), and clearance to combustibles (2 inches interior, 1 inch exterior per IRC R1003.18). Minor tuckpointing and cap replacement are typically exempt.

Required Documents for a Fireplace / Wood Stove Permit in Mobile
You'll typically need the following when applying for a fireplace / wood stove permit in Mobile:
- Building permit application — Filed by licensed contractor. Scope of work, appliance info, installation location.
- Mechanical permit application (for gas appliances and wood stoves) — Separate from building permit in most jurisdictions.
- Appliance manufacturer specifications — Installation instructions, UL listing, EPA certification (for wood stoves), BTU rating (for gas), clearance requirements. Inspectors verify compliance against these specs.
- Chimney/vent specifications — For masonry: flue size calculation, liner specs. For factory-built: vent type, diameter, routing plan, termination location.
- Site plan / elevation drawings — Required for masonry fireplaces and any work affecting exterior appearance. Shows chimney termination height and relationship to roof and other structures.
- Gas line plan (for gas appliances) — Shows gas line routing, size, connection point, and shutoff valve location. Required for gas insert installations.
Requirements may vary. Contact Build Mobile Department for the complete list of required documents.
Common Mistakes to Avoid in Mobile
Skipping the permit because 'it's just a wood stove'
Wood stove installations cause a significant portion of residential fires. The permit process ensures proper clearances, floor protection, chimney connection, and installation. Unpermitted wood stoves create insurance problems (denied fire claims), home sale problems (inspector flags it), and genuine safety risks. The $75-$250 permit is worth it.
Inadequate clearance to combustibles
The single most common wood stove installation error is insufficient clearance to walls. NFPA 211 requires 36 inches from unprotected combustible walls. Reducing that clearance requires factory-listed heat shields or proper wall protection per NFPA 211 Table 10.3.5. Not following the exact specifications causes wall overheating, which can ignite framing behind drywall — often not discovered until years later.
Wrong chimney type for the appliance
Different appliances require different chimney ratings. Wood stoves need UL 103 Type HT (high-temperature) chimneys, marked with 'Type HT' labels. Gas atmospheric appliances need Type B vent. Direct-vent gas fireplaces use co-axial sealed venting. Using the wrong type — like Type B vent on a wood stove — can cause chimney fires and structural damage.
Missing or undersized hearth extension
IRC R1001.10 specifies minimum hearth extensions: 16 inches in front and 8 inches each side for fireboxes under 6 sq ft, 20 inches in front and 12 inches each side for larger fireboxes. This protects combustible flooring from ember strikes. Inspectors specifically check this — undersized hearths fail inspection every time.
Not EPA-certified wood stove
As of May 15, 2020, all new wood stoves sold in the US must meet 2.0 g/hr particulate emissions (EPA NSPS Subpart AAA). Installing an older uncertified stove is illegal in most jurisdictions. Buying a used wood stove? Verify it's on EPA's certified database before purchasing. Uncertified stoves cannot legally be installed as residential heating appliances.
Ignoring California air district restrictions
Several California air districts ban new wood-burning fireplaces in new construction (SCAQMD Rule 445, BAAQMD Regulation 6 Rule 3, SJVAPCD Rule 4901). If you're in these districts, your options are limited to gas, pellet stoves, or certified low-emission EPA Phase 2 fireplaces. Check before planning. During 'No Burn Days,' operating any wood-burning appliance can result in fines up to $500.
DIY gas fireplace installation
Gas fireplace work requires a licensed gas fitter in virtually all states. Gas line sizing, pressure testing, and appliance connection are not DIY work. Improperly installed gas fireplaces can leak carbon monoxide into the home — silent, deadly, and invisible. Always use a licensed professional.
Not installing carbon monoxide detectors
IRC R315 (Carbon Monoxide Alarms) requires CO detectors in residences with fuel-burning appliances or attached garages. After installing any fireplace or wood stove, verify working CO detectors are in place, especially near bedrooms. Inspectors may check for these during final inspection.
Required Inspections in Mobile
Most fireplace / wood stove projects in Mobile require inspections at each construction stage:
Framing inspection (for new fireplace in a wall)
When: Before walls are closed up
Framing clearances around the fireplace unit, chimney chase framing, fire blocking, proper structural support for weight of appliance and chimney, and clearances to combustibles.
Common failures: Framing too close to unit, missing fire blocks, inadequate structural support.
Masonry fireplace inspections (multiple stages)
When: Footing, firebox complete, smoke chamber complete, chimney complete
Footing dimensions and reinforcement, firebox dimensions per IRC R1001.7, throat opening, damper location, flue liner installation and alignment, chimney construction, cap installation, 2-10-3 rule for termination height.
Common failures: Undersized firebox, improperly sized throat, flue liner gaps, chimney termination too low, hearth thickness insufficient.
Mechanical / gas inspection (for gas appliances)
When: After gas line is complete and appliance is installed
Gas line pressure test per IFGC 406 (3 psig for 10 minutes), pipe sizing for BTU load, shutoff valve location, sediment trap, proper venting type and size, clearances to combustibles, combustion air supply.
Common failures: Pressure test failure (leak), undersized gas line, wrong venting type, inadequate clearances.
Final inspection
When: After all work is complete
Appliance matches permit application, UL listing intact, clearances to combustibles meet manufacturer specs, hearth extension in place with correct dimensions, chimney termination correct, working carbon monoxide detectors nearby, doors/glass installed and operational, overall installation matches the approved plans.
Common failures: Clearances shortcuts, missing or undersized hearth extension, missing CO detectors, chimney termination too low.
Schedule inspections with Build Mobile Department at (251) 208-7696 at least 24–48 hours in advance.
Pro Tips for Fireplace / Wood Stove Permits in Mobile
- Get a CSIA-certified (Chimney Safety Institute of America) inspection before buying a house with a fireplace. Even a visually fine chimney can have cracked flue liners, creosote buildup, or structural issues that cost thousands to repair.
- For wood stoves, look for EPA 2020-certified units with cord wood testing method — these are typically cleaner-burning and more efficient than the traditional test method. Budget around $1,500-$4,000 for the stove itself, plus installation.
- Gas fireplace inserts are a popular retrofit for old wood-burning fireplaces. They're cleaner, lower maintenance, and provide reliable heat — but they cost $2,500-$8,000 installed and require gas line work. Consider whether the convenience is worth the cost over a cleaned-up wood-burning fireplace.
- Pellet stoves are a middle-ground option: EPA-certified, easier to operate than wood stoves, clean-burning, and cheaper to fuel than gas. Downsides: they require electricity (so no heat during power outages), need regular cleaning, and pellets are bulky to store.
- For California residents: check your air district's rules before planning. SCAQMD (LA basin), BAAQMD (SF Bay Area), and SJVAPCD (Central Valley) all have new wood-burning restrictions. Sacramento, San Diego, and other districts have their own rules too.
- Chimney caps are small but important: they keep rain out (prevents freeze damage to flue), keep animals out (bird nests block flue), and act as spark arrestors. A $75-$300 cap can save $1,000s in future chimney repairs.
- Annual chimney inspection is recommended — NFPA 211 specifies at least annual inspection by a qualified sweep. Costs $100-$300 and can catch problems before they become major.
- Know your home's history. If you bought a home with a fireplace but no permit records, have it inspected before using it. Unpermitted or grandfathered fireplaces may have hidden safety issues.
- Insurance carriers care about fireplaces. Notify your insurance company about any new installation — many require documentation of EPA certification and permit compliance for coverage.
- For remodels: if you're removing an unused fireplace, you still need a permit for the demolition, especially if the chimney penetrates the roof or is part of a structural wall. Improperly removed chimneys can cause roof leaks.
